The Silence of Malka
Written by Jorge Zentner and Illustrated Rubén Pellejero
Winner of the Best Foreign Graphic Album award at the Angoulême Festival.
Inspired by a story told to him by his grandmother, Jorge Zentner has fashioned a tale that is ostensibly about the migration to South America of Ashkenazi Jews fleeing the pogroms in Russia at the end of the 19th Century, but is also a parable of the making of a modern society and the extent to which religion and mysticism meet.
For the family of the little red-headed Malka, trading the Russian shtetl for the Argentine pampas isn’t so easy. Even in a country eager to populate its vast territories, the immigrants discover that their new home isn’t the promised land. They encounter hostility from both man and nature, as they struggle through droughts and locusts in an attempt to cultivate the arid soil. When misery pushes them to the extreme, Malka’s uncle is visited by the prophet Elias, who advises that he create a Golem—the mythical creature fashioned from the earth and endowed with life by engraving on his body the word Emet (“Truth”)—to pose as a man and aid the immigrants. Malka is told about the Golem, provided she promises to keep the secret.
When years later the adult Malka is visited by Elias, the events of her youth force her to decide whether or not she can maintain her silence—with fate and divine justice hanging in the balance.
This sweeping and poignant story is masterfully drawn in a luminous palette by Rubén Pellejero.

CHENNAI: Encroachments on 2.4 acres of land belonging to Sri Arulmigu Somanatheeswarar temple at Kolathur were removed on Monday.
Hindu Religious and Charitable Endowments (HR&CE) officials with the help of revenue and police officials evicted two contractors of Chennai Corporation who used the land to store materials like steel bars, cement sheets and to process the materials. Also a car mechanic shop and another temporary shed were demolished using JCB excavation machines.
The land is worth Rs 25 crore in the current market rate. An official of the HR&CE department said: "The encroachers refused to vacate the land even though we showed proof including survey details and asked them to move. As they refused, we used JCBs and requested police help to evict them."
HR&CE is battling with encroachments on its lands across the city. Last year, a piece of prime land which is under the occupation of a political party's outfit on Butt Road, St Thomas Mount was evicted with police help and immediately the matter was taken to court and status quo persists now. Again this land is worth several crores and a small temple without any source of income owns the land.

Director of Teylers Museum (1983 – 2001) (B. 1940)
Since 1983, Teylers Museum has been run not only by its Foundation, but also by its own director. The first*, from 1983 to 2001, was Eric Ebbinge, who originally studied law in Amsterdam, and who also attended a visual arts course in Haarlem.
It was under his directorship that work took place on Teylers' Zegelwaarden workshops and depot, and on Hubert Jan Henket's new building in 1996. Ebbinge thus helped reinforce the Museum's identity as the Netherlands' oldest museum, to which he simultaneously added a strong contemporary dimension. With the acquisition of work by artists such as Lucassen, Waldo Bien, Helen Frik, Otto Egberts and Marlene Dumas, he also breathed new life into contemporary drawing.
*) ‘First' is not strictly accurate, as Van Marum and Van Breda both held this position, but only within their own fields of study.

This week, Eurogamer released an article detailing exactly what the NX is, according to "a number of sources". Unnamed sources, of course, but we'd assume they're trustworthy.
Whether you believe it or not, it's looking incredibly likely that the Nintendo NX is a console / handheld hybrid, has a detachable controller, and will go back to using cartridges.
Our first thought on reading these rumours - aside from absolute joy - was "I wonder what the App Army thinks of this?"
Well wonder no longer. We reached straight out to our team of mobile experts to learn exactly what they think of the rumoured Nintendo NX. Read on for their thoughts.
Hm. I like the idea of having cartridges but I feel like the NX is going to lose third party support after just a few months. Hopefully, it'll be more powerful than the PS4 / Xbone - or even the Neo / Scorpio.
Reggie Fils-Aime claimed recently that games should always come before hardware - and that's a good thing. But I remember him saying exactly the same about the Wii U and we all know what that lead to. I only have four games for the Wii U - none of which I play regularly.
I will personally not buy the NX unless it turns out to be really good.
Anyways let's just enjoy this picture of Reggie reacting to the Xbox S:
If I was going to buy it I guess I'd want it to be super portable. I always have my phone with me so I've got that to play games on. Having an extra device that only plays games would be a faff if it was bulky!
It has to be powerful enough that it isn't left in the dust when the latest Xbox and PlayStation come out, so third parties will continue to support it.
Plenty of RAM and a decent GPU would be a start - And a battery that lasts more than a few hours.
Wouldn't it be awesome if they release some real cutting edge gaming hardware that just blows everyone away? I want to see something that makes me think "I need to buy one of those".
I'm not a user of the latest Nintendo devices but I think I heard from Danny that if you lose your 3DS (or any Nintendo console), you lose the games that you've bought for it. It doesn't work that way on PSP or PS Vita.
Nintendo needs a unified system for all of their devices, otherwise it may discourage some people from buying their products.
They had me at Cartridges!
I'm struggling to see the point. A handheld for people with mobiles or a weak console for people with PS4s and Xbox Ones. It had better be cheap which it probably won't be.
I hope amiibo continue to be produced when the NX comes out, hopefully with more varied uses. Battery life is key since the default battery on the Wii U gamepad is horrible - even with energy saving configurations.
The 3DS can be used as a controller for certain games on Wii U, would love to see how they improve on that.
Continuing the Virtual Console service would be great since I get to relive classic games on my Wii U and 3DS XL. I do hope there will be some sort of connection to their mobile games lineup. That would be rather interesting to watch.
I'm personally excited about the concept. As a mobile gamer, I'm well aware of how capable mobile chipsets have become and how adept developers are at fully utilizing them. Having the ability to use your system on a big screen and mobility is the best of both worlds.
I fear though that it's going to be very challenging for Nintendo to market it. Gamers can be a pretty fickle bunch and they're known to snub their nose at hardware they perceive to be inferior. Which is a real shame because gaming should be about great gameplay not fancy graphics.

Nematic and spin-charge orders driven by hole-doping a charge-transfer insulator
Recent experimental discoveries have brought a diverse set of broken symmetry states to the center stage of research on cuprate superconductors. Here, we focus on a thematic understanding of the diverse phenomenology by exploring a strong-coupling mechanism of symmetry breaking driven by frustration of antiferromagnetic order. We achieve this through a variational study of a three-band model of the CuO plane with Kondo-type exchange couplings between doped oxygen holes and classical copper spins. Two main findings from this strong-coupling multi-band perspective are 1) that the symmetry hierarchy of spin stripe, charge stripe, intra-unit-cell nematic order and isotropic phases are all accessible microscopically within the model, 2) many symmetry-breaking patterns compete with energy differences within a few meV per Cu atom to produce a rich phase diagram. These results indicate that the diverse phenomenology of broken-symmetry states in hole-doped antiferromagnetic charge-transfer insulators may indeed arise from hole-doped frustration of antiferromagnetism.
Translational-symmetry breaking in hole-doped La-based nickelates and cuprates in the form of static spin and charge stripes has been well established for almost two decades[1, 2, 3, 4]. However, until recently, the ubiquity of such phenomena had not been clear. The recent surge of experimental discoveries reporting spin or charge order in all families of hole-doped cuprates[5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21] and even in some Fe-based superconductors  has brought the diverse phenomenology of broken-symmetry states to the forefront of study of high T superconductors. In particular there is extensive indication that intra-unit-cell (IUC) orders [15, 16, 11, 18, 19] and (short-ranged) modulations [5, 6, 8, 9, 10, 12] coexist. In this new landscape of ubiquitous and diverse forms of broken-symmetry reports, an emerging central question is whether the diverse set of phenomena share a common origin or if each phenomenon should be studied on its own.
Closely linked to the question of whether a thematic understanding of the observed phenomena is attainable is a theoretical question of whether to take the weak-coupling Fermi-surface instability perspective or to take the strong-coupling perspective. From a Fermi-surface instability perspective, the simultaneous occurrence of multiple orders requires fine tuning as one usually finds a single dominant instability in one ordering channel. For instance, it was shown that antiferromagnetic exchange interactions or short-range repulsive interactions  can drive an instability towards density modulation along an incommensurate vector with a dominantly d-form factor. Although a order with the d-form factor will be equivalent to IUC nematic order observed in various experiments[15, 16], a modulation at finite will not show net IUC nematicity, just as antiferromagnets have no net magnetization. However, from a strong coupling perspective that focuses on the influence of local antiferromagnetic correlations, multiple orders could naturally intertwine.
While it is to be expected on symmetry grounds that a nematic order will be more robust and may coexist with disordered stripes, microscopic studies so far have focused on either finite ordering of spin and charge stripe phenomena[27, 28, 29, 30, 31, 32] or IUC nematic phenomena [33, 34, 35, 36, 37, 17, 14, 38]. Moreover, since simple Hartree-Fock mean-field theories incorrectly predict insulating period-8 stripes[27, 28, 29, 30], the present theoretical understanding of the experimentally observed metallic period-4 charge stripes at doping  is dependent upon elaborate variational numerical studies[39, 40, 41, 42, 43, 31] or the scenario of Coulomb-frustrated phase separation. Our goal is to capture a wide range of spin and charge ordered states, including those experimentally observed, in a simple microscopic model that retains the strong-coupling aspect of hole-doping that enables holes to frustrate antiferromagnetic order in the “parent compound”. A successful demonstration of close energetic competition between diverse outcomes from the same root of local anti-ferromagnetic correlations would be an important step towards thematic understanding of the observed diverse phenomena.
Although it is well known that motion of doped holes will frustrate the antiferromagnetic background of the cuprate “parent compounds” , much of the work on this issue has largely focused on the one-band Hubbard model as a minimal framework to discuss this physics. Nevertheless, a host of experimental observations on cuprate superconductors (e.g., electron-hole doping asymmetry of the phase diagram and unusual broken-symmetry phases with spin and charge order [5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21] at low hole doping) strongly call for a description which explicitly retains the oxygen orbitals. Such multi-orbital models of the CuO plane, like the Emery model , are, however, even less amenable to a theoretical treatment than the one-band Hubbard model.
In this paper, we consider a simplified model which ignores the charge fluctuation on the transition metal sites and treat the spins on those sites as classical local moments that interact with doped itinerant holes living on the oxygen sites through a Kondo type coupling (see Figure 1). This is a tractable three-orbital model that retains the spatial separation between the local moments on Cu and the doped holes that predominantly go into oxygen sites. We consider several plausible spin-order patterns and exactly solve for the many-hole eigenstates associated with the spin-order patterns. This way we can access not only the lowest energy spin-hole configuration, but investigate how magnetism drives charge physics in the cuprates, study the energetic competition between a wide range of spin and charge ordered states, and gain insight into the interplay between spin and intra-unit-cell nematic orders.
Before proceeding to the model Hamiltonian and our analysis, we clarify the nature of the charge and spin order parameters that will characterize the various phases we consider in the paper. We define the IUC nematic order parameter, which measures the inequivalence of the hole density between the - and -oxygen sites within the CuO unit cell as
where and are the expectation value of the hole density at the - and - oxygen sites respectively. The charge stripe order parameter is also extracted from the hole density as the Fourier component at a finite , . Finally, spin stripe and spiral order parameters of interest are Fourier components of the spin density at a finite , where is either co-linear (stripe) or co-planar (spiral). From a symmetry perspective, any state with non-zero or for one Q (i.e., uni-directional modulation), breaks spatial rotational symmetry as well as translational symmetry. Such a phase is referred to as electronic smectic . When the modulation vector lies along the Cu-O bond direction, there will be a symmetry allowed coupling between the modulation order parameters and the IUC nematic order parameter resulting in in the presence of long range modulational order,i.e., or . Hence, a discussion of the IUC nematic order parameter for our ansatz modulational states may appear inconsequential. However, when heterogeneity and thermal fluctuations cause the experimentally observed modulational orders to be short-ranged, a microsopic understanding of how the IUC nematic order parameter can locally relate to spin and charge modulations is crucial in making contact between theory and experiments . Hence, we believe it is important to study the microscopic behavior of both order parameters even for the case of ideal long-ranged modulations.
The rest of the paper is organized as follows. In section 2 we introduce and motivate the model as well as the choice of some parameters. In section 3 we discuss the choice of spin-ordering configuration ansätze. In section 4 we discuss the charge-ordered states we obtain associated with each spin-ordering configuration. In section 5 we discuss the energy differences between different ansätze and the phase diagram. In section 6 the effect of a nearest-neighbor oxygen-oxygen interaction is analyzed. Finally, we conclude with a summary and discussion in section 7.
In this paper we restrict our attention to the Hilbert space with singly occupied Cu orbitals represented as local moments that interact antiferromagnetically. The doped holes will be assumed to go into the oxygen or orbitals. These holes couple to the local moments on Cu sites through both (spin-dependent) hopping between O sites mediated by Cu sites and spin-spin interactions. Treating the moments on the Cu sites classically, we arrive at a model Hamiltonian
where are the oxygen hole annihilation operators at oxygen site with spin , is a classical spin vector at Cu-site with , and are the Pauli matrices. The first two terms represent two hopping processes through the Cu sites, the () process with hole spin anti-parallel (parallel) to . These hopping processes amount to nearest- and next-nearest-neighbor hopping on the lattice of oxygen sites. Note that the second term in equation (2) hence introduces coupling between the motion of the holes on O-sites and the spin on the Cu sites. The third term represents direct hopping between O-sites, which amounts to nearest-neighbor hopping on the lattice of oxygen sites. The last two terms represent exchange coupling between Cu spins (the term) and between a Cu spin and the hole spin on a neighboring O site (the term).
The model Hamiltonian of equation (2) is a simplified form of a perturbative expansion in Cu-O hopping (to order ) in the large Coulomb interaction limit of the Emery model Hamiltonian for the cuprates : with
However, the actual model obtained through such perturbative expansion is still highly non-trivial as it does not allow double occupancy at oxygen sites and the spins on Cu-sites should be quantum mechanical spins. Frenkel et al studied the exact quantum ground state of such a model in the presence of a single hole in a small cluster. Despite the reduction of the Hilbert space due to the constraint of singly occupied Cu orbitals, the largest cluster they could study was a Cu-O cluster which would be too small to see the observed stripe phenomena. Such studies have been extended to larger clusters  with the aim of understanding spin polaron formation in a 3-band model. However, this exact diagonalization study is restricted to 1-hole and 2-hole states in the undoped insulator and thus cannot address doping dependent competing orders. By treating the local moments on Cu sites to be classical and relaxing the no-double-occupancy constraint on oxygen sites, we arrive at the more tractable model Hamiltonian of equation (2).
Our simple model has several features. Firstly, it is a solvable model that retains much of the microscopic details and non-trivial interactions of under-doped cuprates. The solvability of the model allows us to study a wide variety of states including incommensurate orderings. Secondly, we expect similar effective models are applicable to other doped strongly-correlated charge-transfer insulators such as the nickelates. In particular, a classical approximation of the local moment on the transition-metal ion is likely to be a better approximation in Ni given its larger moment. Finally, through spatial separation between spins and holes, the model offers a rich playground for strong-coupling-driven spin and charge orders co-existing with intra-unit-cell nematic order.
Earlier consideration of the strong-coupling limit of the Emery model by Kivelson et al.  focused on the limit of vanishing inter-oxygen site hopping. In that limit, the dynamics is strictly one-dimensional and hence the ground state is a nematic phase. Three key differences between the limit considered in Ref.  and the limit captured by our model equation (2) are that 1) we have taken to be so strong to the extent that we suppressed the charge fluctuation in the Cu sites, 2) we consider inter-oxygen hopping to be comparable to exchange interactions, and 3) we take the Cu-O exchange interaction into account. As a result, the charge dynamics in our model is strictly two dimensional. However we make the approximation of leaving out and which yields an exactly solvable model for the hole motion on a system size that can exhibit translational symmetry breaking. This approximation may not affect the conclusions qualitatively in the limit of dilute hole density.
Although the model Hamiltonian has quite a few parameters, many of them are constrained by experiments. We use a Cu-Cu exchange interaction meV, close to the value estimated for LaCuO from neutron scattering studies of the spin-wave dispersion . In order to constrain hopping strengths, we examine the dispersion of a single hole doped in an ordered Néel antiferromagnet. We can diagonalize the hole Hamiltonian assuming an out of plane spin moment on Cu atoms in an antiferromagnetic arrangement, i.e. , and obtain four dispersing bands (see A). The resulting lowest dispersion can be compared to the ARPES measurements on extremely underdoped cuprates . Although the ARPES energy distribution curves are broad, we can infer the following energy scales from the peak positions. The binding energy at is lower than that at by about meV, which corresponds to ; this fixes meV. Shen et al.  also found that the spectral peaks disperse by about eV going from the -point to . In our model, this energy difference is just ; this fixes meV. Cluster diagonalization calculations in Ref. [49, 53] indicate that is the same sign as , with . We therefore examine a range of values . The above choice of hopping parameters yields a Fermi surface consisting of hole-pockets centered at for the holes (see Fig. 1(b)), consistent with the energy minimum of a single hole in the Néel ordered antiferromagnet being centered at . We expect the antiferromagnetic Cu-O exchange interaction , which is only present at finite doping, to be stronger than the Cu-Cu exchange . Hence we explore a range of . We note that our values for the parameters in the effective Hamiltonian for doped holes differ slightly from those used in previous work [49, 53, 54] - the values we use should be viewed as effective couplings given our assumption of a classical copper spin. They also place the regime of interest in the strong coupling limit, since and are much greater than the free fermion bandwidth set by and motivate the use of a variational approach as discussed in the next and following sections.
3 Ansätze for spin-order configurations
The key mechanism by which the model Hamiltonian of equation (2) drives spin and charge order at finite doping is the frustration of antiferromagnetic order in the parent compound (i.e., zero doping). The undoped cuprate and nickelate insulators are ordered antiferromagnets, possessing long-range Néel order in planes which are stacked along the axis. The planar Néel order has a wavevector and is a collinear state with with being a unit vector. Doped oxygen holes frustrate the antiferromagnetic alignment of Cu moments driven by the Cu-Cu exchange through a strong antiferromagnetic Cu-O exchange interaction . Thus, doped holes promote a ferromagnetic arrangement of the two neighboring local Cu-moments and drive spatial symmetry breaking in the spin configuration. Interestingly, such frustration is not expected in the electron-doped cuprates, where doped electrons go onto Cu sites. This naturally explains why the Néel order is present to much higher doping in electron doped cuprates whereas the hole-doped cuprates exhibit various broken-symmetry states.
While ultimately the model equation (2) can be exactly solved by combining Monte Carlo simulation of the spin problem with the exact diagonalization of the fermion problem, we here consider two classes of spin-order configurations and solve the fermion problem within each class. This approach offers us an understanding of the parameter-space landscape. Moreover, although our understanding is limited to the set of ansatz spin patterns we consider, this approach has the advantage over the explicit solution in that it allows us to compare energetics of different candidate states. The two classes we consider are coplanar spin spirals and collinear spin stripes with different wave vector . As there is much literature on both of these candidate states we defer in-depth discussion to review articles (see e.g., [55, 56]). Rather, we discuss aspects of these states that are directly relevant to our study and the rationale for their consideration below.
(i) Coplanar spin spirals: While a doped hole promotes ferromagnetic correlations of the local moments in its vicinity, the spins far from the hole maintain their Néel correlations. Hence, in the absence of magnetic anisotropy a coplanar spiral state may be expected as a solution that interpolates between the Néel order and ferromagnetism when holes are doped into a quantum antiferromagnet as it has been argued in Ref. . However, spiral states are accompanied by translationally invariant charge distribution and they are unstable against magnetic anisotropy as well as phase separation. Further, susceptibility studies in spin-ordered cuprates are consistent with collinear order. However, the smoking-gun polarized neutron scattering experiment has not been performed to date and local spiral distortions of the spin background may be an appropriate picture in the insulating regime at low doping .
Below, we pick the spiral to lie in the plane, setting , and consider different propagation wavevectors running parallel to the Cu-O bonds (labelled Psp1, Psp2) or along the diagonal direction (Dsp), see Fig. 2, and compute their physical properties and energies. We show that within a three-orbital picture, the spin spirals with a wavevector parallel to the Cu-O bonds are naturally accompanied by a translationally invariant oxygen hole density, but with charge nematic order on the oxygen sites as has been observed in STS experiments. This opens up a possibility of disordered spiral leaving the discrete and robust nematic order as the only observable effect. Similar ideas have been perviously considered in the context of frustrated magnets .
(ii) Stripes: Two theoretical approaches discussed stripes prior to their experimental observations. The first approach was that of Hartree-Fock mean-field theory [27, 28, 29, 30] which predicted insulating (fully filled) period-8 charge stripes at doping. The other approach was built on the observation that phase separation should be expected in - models for , where ‘slow’ doped holes cluster together to avoid disrupting the Néel order of the local moments. This led to the proposal that stripe orders could emerge as periodic density modulations due to frustration of such phase separation by long-range Coulomb interactions. Following the experimental observation of metallic period-4 charge stripe at doping in La-based cuprates, theoretical efforts focused on going beyond Hartree-Fock mean-field theory to obtain the observed metallic stripe [39, 40, 41, 42, 43, 31]. A particularly convincing case was made by a density matrix renormalization group study by White and Scalapino which not only obtained the observed metallic stripe ground states at but also demonstrated that anti-phase domain walls between collinear antiferromagnetic domains attract charge stripes. This issue of charge stripe periodicity (period-4 and metallic v.s. period-8 and insulating) bears particular importance in the discussion of the role of charge stripes in superconductivity. However, most previous efforts at going beyond Hartree-Fock mean-field theory and incorporating strong-coupling physics relied on sophisticated numerics. The spatial separation of Cu-moment and doped holes in our model allows us to investigate the complex spin-charge interplay in the strong-coupling regime in a transparent manner. In our model, spin-antiphase domain walls can form upon hole-doping to relieve the frustration between the AFM order favored by Cu-Cu antiferromagnetic superexchange interactions and the ferromagnetic order favored by an antiferromagnetic Cu-O exchange.
We model the spin stripes as antiphase domain walls in the collinear antiferromagnet and consider several different uni-directional domain-wall configurations depending on the direction of periodicity as well as the period. Note that these spin stripes will be bond-centered by construction. We consider parallel stripes with wave vectors along the Cu-O bond directions as well as diagonal stripes with at 45 angle with respect to Cu-O bond direction. At fixed hole density of , different periods determine whether the stripe can support metallic transport along the stripe: period-4 parallel charge stripe (labeled , see Fig 2) will be half-filled and metallic while period-8 parallel charge stripe (labeled , see Fig 2) will be fully-filled and insulating. Similarly, one can consider metallic (labeled , see Fig 2) and insulating (labeled , see Fig 2) diagonal stripes.
4 Charge orders associated with different spin-order ansätze
For each spin-order candidate, we diagonalize the (quadratic) hole Hamiltonian and use the resulting lowest-energy many-hole wave function and the spin configuration to evaluate the total energy for the spin-charge-ordered state. The total energy for a given spin configuration at a given doping , with the number of Cu-O unit cells, is given by
where are the (energy-ordered) eigenvalues of the Hamiltonian (2) for the given configuration . In equation (5) the last term is the interaction energy due to Cu-Cu exchange (the term in equation (2)).
For the spiral configurations given by we take advantage of a closed form of the Hamiltonian equation (2) in momentum space (See A) to find the wave vector that minimizes the energy for each spiral. Fig. 3 shows the lowest-energy charge distribution for a parallel spiral (Fig. 3(a)) and a diagonal spiral (Fig. 3(b)) spin configurations. Though it is well known that spiral order of spins would not be accompanied by any charge modulation, Fig. 3(a) shows that parallel-spiral tendency drives IUC nematic charge order (for meV and meV, we find for the Cu-spin configuration in Figure 3). Note that even when the spiral order of the spins is disordered due to thermal or quantum fluctuations, the discrete symmetry breaking of IUC nematic in the charge sector can be more robust.
For the collinear stripe configurations, we consider a lattice of unit cells (2048 oxygen sites) and diagonalize the quadratic Hamiltonian of the holes only living on the oxygen site, equation (2). The resulting charge-order patterns for different trial spin configurations (see Fig. 4) clearly show that the holes are attracted to the anti-phase domain walls in the spin configurations driven by the Cu-O exchange-coupling . The kinetic terms broaden the hole distribution and favor the metallic charge stripe. It is remarkable that our simple model can readily access the spin and charge striped ground-state configuration reminiscent of those obtained in density matrix renormalization group studies of the -doped - model. Moreover, as this model incorporates the mostly-oxygen character of doped holes, the charge stripes centered at the anti-phase domain wall of the antiferromagnetic background are naturally coupled to IUC nematic. The parallel stripe configurations obtained in Fig. 4 clearly demonstrate a coupling between the (Ising) IUC nematic order and the stripe-ordering wave vector. In the sense of Ginzburg-Landau theory of order parameters, Fig. 4 demonstrates a coupling between the Ising nematic order parameter and the difference in amplitude of the charge-density wave (CDW) order parameters for CDW’s propagating along the two Cu-O bond directions at a microscopic level. The charge distribution we obtain for trial spin configurations in Figs. 3 and 4 makes it clear that any spin order with modulation vector along the Cu-O bond direction will be accompanied by IUC nematic irrespective of charge stripe order. 111On symmetry grounds, any unidirectional spin order along Cu-O bond direction breaks the point group symmetry and hence it can, in principle, couple to nematic order parameter; what is new here is an explicit microscopic realization of such a coupling. The remaining question is which of these candidate states is lowest in energy and what are the energy differences between competing states.
5 Phase diagram
While our variational study is limited by the choice of states we consider, it has the advantage of allowing the energetic comparison between different candidate states over Hartree-Fock or variational Monte Carlo studies. Surprisingly, we find the entire collection of states we consider to show close energetic competition. For the most part of the parameter space we consider (varying hopping through Cu and Cu-O exchange ) different states differ in energy only by a few meV. The close energetic competition is clear in Figure 5 which shows energy differences as a function of at fixed meV. Such close competition indicates small perturbations to our model Hamiltonian such as spin-orbit coupling or lattice anisotropies could change the phase diagram significantly.
It is well known that incorporating quantum fluctuations of spins strongly favors collinear order over coplanar or non-coplanar states [63, 64], Similarly, spin anisotropy due to weak spin-orbit coupling could also hinder coplanar spirals. We therefore present two phase diagrams here: a phase diagram that includes co-planar spiral and a phase diagram that only concerns collinear orders. Figure 6(a) shows the phase diagram that allows for co-planar spiral as a function of hopping through Cu-sites and the Cu-O exchange . We have limited the plotting range of to be a reasonable range of meV meV. Figure 6(a) shows that the lowest-energy configuration with the parameters motivated from cuprates is dominated by diagonal orders such as diagonal spiral or diagonal metallic stripe. In the limit of large (not shown), parallel spiral with IUC nematic appears before Cu spins align ferromagnetically. Figure 6(b) shows the phase diagram restricted to collinear orders. Notably metallic diagonal and parallel stripe orders appear in a substantial region of the phase diagram. The close competition between diagonal stripe order and parallel stripe order is remarkable in light of the experimentally known transition from diagonal to parallel stripe upon doping. The parallel metallic charge stripe order (PM) at is consistent with observations in La-based compounds[65, 66] as well as those in Bi-based compounds [15, 62, 5, 6].
The microscopic tie between spin-ordering patterns and charge-ordering patterns resulting from our simple model depicted in Figs. 3 and 4 hints at a microscopic mechanism of charge order without spin order at finite temperature. The spin orders under consideration require breaking of spin rotational symmetry as well as spatial translation and point-group symmetries while charge orders only break spatial symmetries. While the driving force for charge order in our model is the frustration of antiferromagnetic order upon holes entering oxygen sites, fluctuations in spin space will suppress spin order. It has been shown in the context of Fe-based superconductors that spin fluctuations in the absence of spin order () can drive nematicity. Similarly, since the cuprates are quasi-2D systems, it is quite plausible that thermal fluctuations may prevent spin order in the stripe state, while may still leave the charge order visible. This can be easily seen by the fact that the charge stripe and IUC nematic in the parallel stripe phases in Fig. 4 as well as IUC nematic in the parallel spiral phase in Fig. 3 are insensitive to the spin-orientation, so (thermal) averaging over the global spin orientation will leave these orders unaffected. Hence, charge order in Fig. 3 can onset without detectable spin order or with a lower temperature transition into a state with coexisting spin order. This would amount to a microscopic realization of a so-called “charge-driven transition” in the Landau theory study Ref. . Experimental observations of charge and/or spin order in cuprate families broadly show such preferential visibility of charge order [65, 66, 15, 62, 10, 9, 8, 5, 6].
6 Effects of inter-oxygen repulsion
As IUC nematic naturally accompanies all modulations along the Cu-O bond directions within our model, it is natural to ask what would be the effect of the inter-oxygen repulsion that was found to drive IUC nematic [38, 51]. Recently Bulut et al.  extended the mean-field study by two of us  to include the charge-density wave instability as well as IUC nematic instability. They found the d-form factor component , defined on oxygen sites using the notation of Ref.  via
where () is zero (one) on copper sites and one (zero) on oxygen sites and is zero on copper sites, one on x oriented oxygen sites and minus one on y-oriented oxygen sites, to dominate the density wave instability along the Brillouin zone diagonal. While different form-factor components of density waves are not symmetry distinct, experimental observation of the d-form factor [5, 70] hints at the importance of microscopic interactions promoting an anti-phase relation between the two oxygen sites.
As charge fluctuations on Cu-sites have been projected out in our model (), charge stripes found in our model consist only of s’- and d-form factor components. In order to study the effect of on the charge configurations associated with candidate spin configurations, we treat the term at the level of self-consistent Hartree approximation. As experiments observe IUC nematic simultaneously with short-ranged d-form factor density waves  we focused the study to the parameter space where a Cu-O bond-direction charge stripe is present in the absence of .
On symmetry grounds, , and IUC nematic order parameter can form a cubic coupling within Landau theory. Hence, we generically expect both s’- and d- form factor components to be present given the robust IUC nematicity coexisting with charge stripes in our charge-ordering patterns. For meV, meV, figure 7 shows the resulting ratio of the d- and s’- form factor components. While the density waves we obtained for the PM configuration have predominantly s’-form factor, Fig. 7 clearly shows that promotes a d-form factor for the charge stripe along the Cu-O bond direction with the wave vector consistent with the experimental observations.
To summarize, we considered a three-orbital model for underdoped cuprates, which incorporates strong-coupling physics through singly occupied Cu-sites hosting local moments and reflects the charge-transfer energy through constraining holes to live on the oxygen sites. We took a variational approach for the spin configurations and solved for many-hole states exactly for each configuration at doping. We found that the balance between the Cu-Cu exchange interaction, the kinetic energy of holes and the Kondo type coupling between the Cu spins and the spin of the holes conspire to a rich phase diagram featuring several experimentally observed phases. What is more interesting is the close energetic competition between the candidate states such as co-planar spirals, diagonal stripes and parallel stripes with different wave lengths. Within this model, any parallel order including co-planar spiral orders exhibit non-zero IUC nematic order parameter, providing a microscopic mechanism for robustness of a IUC nematic. The mechanism for nematicity considered in this paper differs from the weak-coupling fermi-surface instability driven by a so-called interaction [35, 36] or inter-oxygen repulsion  in that we focus on the strong local antiferromagnetic correlations between singly occupied Cu sites as the driving force for nematicity.
Though we studied the parameter space constrained by various experiments on the cuprates, our model can be applied to other transition metal oxides like the doped nickelates which exhibit similar spin-charge ordered states as cuprates . In the nickelates, a local moment at Ni sites may arise from the effect of strong Hund’s coupling between two electrons (or two holes) in the two orbitals, leading to an orbital singlet and a spin-triplet state. This spin-triplet nature of the local moment suppresses hopping through Ni sites which renders the system insulating at all doping () without ever exhibiting superconductivity. Antiferromagnetism is more robust in Nickelates and extends to hole concentration of before it is replaced by fully filled diagonal stripe order. Indeed, we find the diagonal insulating stripe as most favored co-linear order in the limit .
Recently, several model studies investigating the Fermi-surface instability towards formation of charge-density waves[71, 23, 72, 73, 24, 74] have found charge-density waves with predominantly d-form factor. Some theories focused on the “hot spot” regions of the Fermi surface, where antiferromagnetic scattering will be especially strong near the antiferromagnetic quantum critical point [71, 23], while others considered one-band models with d-form factor interactions[72, 73] or a three-band model. Though the prominence of the d-form factor component in the density waves appear compatible with experiments[5, 70], these models universally obtained charge-density waves with the wave vector along the Brillouin zone diagonal, i.e., diagonal stripes. This direction and the magnitude of the wave vector is at odds with experimental findings of parallel stripes. More recently, Atkinson et al  showed that the wave vector found in Ref. can be rotated to lie in the Cu-O bond direction by assuming large staggered moments which reconstruct the Fermi surface. However, experimentally it is known that antiferromagnetic fluctuations at are replaced by incommensurate magnetic peaks at temperatures well above the charge ordering temperature in inelastic neutron scattering at low energies [75, 65]. Moreover, nematic ordering which appears to be most robust in experiments, only appear as sub-dominant instability in these Fermi-surface instability studies [71, 23, 72, 73, 24, 74].
In this paper, we took a strong-coupling approach of projecting out charge fluctuation at the Cu-sites yet dealing with an exactly solvable model by ignoring quantum fluctuations of spins at the Cu-sites. In this approach, we found IUC nematic to naturally coexist with any modulation along the Cu-O direction be it co-planar spiral or collinear spin stripes. This is in contrast with weak-coupling Fermi-surface-instability approaches finding competition between order and density waves. Also, we find various experimentally observed charge-ordered states (diagonal insulating stripe, diagonal metallic stripe, parallel metallic stripe) to dominate at different parts of the physically-motivated parameter space exhibiting a close competition. The understanding of the parameter space of our model we gained from the present variational approach can guide us in the attempt for a more explicit exact solution of the model combining Monte Carlo simulations with exact diagonalization.
Before closing, we turn to the implications of our results for the experimentally observed broken symmetry states in different cuprate families (summarized in Refs. [76, 47, 77]). Although d-wave superconductivity is robust in all the cuprate families, the recent detection of charge order in YBaCuO reveals material specific differences regarding the issue of competing broken symmetry states. The La-214 family exhibits spin order at wave vector where and are spin and charge modulation wave vectors respectively, while YBaCuO with does not appear to have static spin order. BSCCO and La-214 families appear to have period-4 charge order at 1/8 doping, while YBaCuO has incommensurate order with a period close to . In BSCCO and La-214, the charge order wavevector grows with increasing hole doping while it appears to shrink in YBaCuO. Nevertheless, all cuprate families indicate incommensurate spin correlations (static or dynamic) whose wavevector grows with doping. Can such a diverse phenomena of competing orders be captured within a unified microscopic framework?
Regarding the issue of spin order, our variational study shows that within our strong coupling mechanism, a long-ranged spin stripe order with wave vector leads to a charge stripe at wave vector . On the other hand, the present study cannot address whether a charge stripe driven by local antiferromagnetic correlations would necessarily require spin order; indeed, broken lattice symmetries might be more stable against quantum and thermal fluctuations, and thus survive even if long-range spin order itself melts. For instance, it has already been shown that when charge order has a higher transition temperature, spin order may or may not occur at the level of Landau theory of coupled order parameters . Regarding the issue of the doping dependence of the ordering wave vector, our present study has only focused on one doping of . Here we found the period-4 metallic to be the lowest energy state in a part of the parameter space which is consistent with the wave vectors found in La-214 compounds and BSCCO compounds but different from the wave vector found in YBaCuO at the same doping. However, what is more significant is the finding that the simple model Hamiltonian of Equation (2) can select lowest energy states with varying wave lengths and properties depending on the microscopic parameters. Specifically, the spin correlations in YBaCuO might be more strongly dictated by the Fermi surface of the doped holes, leading to different charge ordering wavevector, which may allow one to reconcile the apparently quite different observed broken symmetries in this family of materials. In conclusion, our results support the view that despite system-specific differences, the various symmetry-breaking phenomena can be driven by same driving force of local magnetic correlations.

Appendix A Diagonalization of the hole Hamiltonian
a.1 Antiferromagnetic configuration
For the long-range Néel antiferromagnetic order, i.e., , the Hamiltonian equation (2) becomes
where the exchange term between O and Cu atoms is zero due to the zero total spin component in the direction. Opposite spin components are decoupled, therefore the hole part of the Hamiltonian can be written as with , . Note that the sum here only runs over the folded Brillouin zone. The momentum part is given by
Diagonalization of the matrices leads to the band structure for spin up and down holes, which are degenerate.
a.2 Spiral configurations
The spiral spin pattern is given by and the Hamiltonian equation (2) can again be written in closed form in momentum space as , now with , where

Proper lawn care techniques and timing can help create a better, drought-resistant lawn in an easier and more environmentally friendly way.
In the spring, it is best to mow your lawn to the height of 2.5-3 inches. Low mowing allows the sun to warm the soil which helps grass grow faster. Be sure to gradually lower the height of your grass, never cutting off more than a third of its height. Spring is a time for herbicides, not fertilizers. Fertilizing at this time promotes warm season weeds, decreases root production, and promotes diseases.
In the summer, it’s best to let your grass grow higher to 3-4 inches. This creates competition with weeds and prevents crabgrass germination. Frequent rainfall is common for Kentucky summers which provides sufficient water for lawns (overwatering your lawn is not helpful). However, if there is a drought or you notice your lawn is dry (you can see footprints), water your grass in the morning until it begins puddling.
Fall is a good time to return to low mowing your lawn. This creates a denser lawn, reduces winter and spring diseases, and makes raking leaves easier. This is the best time for applying fertilizers. Fall fertilization provides better winter color, less frequent spring mowing, fewer summer weeds, less heat stress and summer watering, and less need for chemical inputs throughout the year. Test your soil to see what nutrients it needs. Never fertilize more than is necessary or before it rains.
Extra Tips for a Healthy Lawn
- Water more deeply (not more frequently) to encourage a deeper root system.
- On sloping land, irrigate more slowly to prevent runoff.
- Adjust sprinklers so they are not watering the road or driveway.
- Install a rain barrel to catch rainwater; use the water on your lawn and garden.
- Keep grass at a height of about 3 inches. This will allow for deeper root growth and healthier grass.
- Leave your grass clippings on the lawn; they act as natural fertilizer for your grass.
- Don’t leave grass clippings on driveways, sidewalks, or streets. They will just wash into the storm drain, directly polluting local streams (this means don’t dispose of clippings in streams either)!
- Use natural or compost fertilizer on your lawn.
- Incorporate native plant species into your lawn and garden. They require fewer inputs and provide the best food and habitat for local wildlife.
- Use Integrated Pest Management rather than relying only on chemical pesticides that can be harmful to the environment, children, and pets.
- Plant a rain garden to decrease runoff from stormwater.
- Have your soil tested to determine its nutrient needs. Make fertilizer type and application decisions based on the soil test. This is a step toward becoming a green neighbor! Visit this link to learn more about the green neighbor program.
- If you are interested in hiring help for your lawn, look into choosing a Green Check company to ensure environmentally friendly practices.
The idea that a perfect yard consists of spotless, bright green grass is only a social construct. While grassy lawns do have their benefits, there are alternatives that can be even better for the environment and just as pretty too! Groundcovers, ornamental grasses, evergreen moss, native perennial beds, and even artificial turf are among the alternatives. Groundcovers, moss, and artificial turf provide an open, walkable space just like grass. While incorporating some ornamental grasses and native perennials adds height and interest. Visit Gilmour for more information about the alternatives. If you don’t want to get rid of grass entirely, even shrinking the size of your lawn provides extra benefits. If the topic of how lawns have become a social construct interests you there is lots of information about it on the internet.

E-hailing expert center Grab has affirmed its relationship with actually look at workplaces in its work to lessen petroleum product results.
In a clarification last Friday, the association said its picked carbon projects are assessed and affirmed by dependable carbon workplaces and suppliers.
This recollects the endeavor for Katingan Mentaya in Indonesia – by which carbon rating associations Sylvera and BeZero have unreservedly assessed the endeavor with “AA” and “A”.
Carbon exchanges Southeast Asia, for instance, Bursa Malaysia’s Carbon Exchange and Temasek-back Climate Impact (CIX) in Singapore have recorded the endeavor (likewise), it added.
The association was noting natural gatekeeper canine RimbaWatch, which faulted Grab for greenwashing its impact on ecological change by offering “trash” carbon offsets its purchasers.
Get clients are allowed to pay RM0.20 per ride or RM0.10 for GrabFood or GrabMart orders to adjust the spreads they cause from the ride or transport, which will used for forest area protection projects including the Katingan Mentaya.
RimbaWatch added that the assignment and its inspector, Affirmed Carbon Standard (Verra) are viewed as tricky by keen reporters, NGOs and the insightful world.
Greenpeace in like manner point by point that since the endeavor started in Central Kalimantan, it has reduced the forest area cover provoking neighborhood individuals moving and achieving land conflicts.
While yielding that there is no broad changed carbon market standard, Grab said it would prefer not to markdown carbon credits as a truly financial instrument for long stretch biological incredible.
We will continue to hold a high bar to our suppliers to ensure our picked project maintains its arranged outcome and trust the business will keep on examining the point and work significantly together towards a lower carbon future, it added.
The association similarly said they are working personally with the public power and industry assistants, as well as supporting the difference in its driver-accessories to electrical vehicles and other low-release vehicles as a part of its decarbonisation system.

Chapter 1 : Waiting in the Wings
| ||Rating: 12+||Chapter Reviews: 10|
Background: Font color:
A mighty pain to love it is,
And 'tis a pain that pain to miss;
But of all pains, the greatest pain
It is to love, but love in vain.
- Abraham Cowley
The fire was crackling merrily in the grate. I averted my gaze from it, my eyes roving around the room as my brain ticked overtime.
I was thinking of her again.
I had seen her before. She was pretty, I suppose, and older. In my opinion she was a selfish cow.
She had led him on, then chosen Diggory. There were no second chances. But he obviously didn't think that. Cho didn't really care. Not like I did. Cho had only met him last year; him, with his deep green eyes and welcoming smile. He was so brave, so loyal, so wonderful.
I had known him ever since Ron had started at Hogwarts. I knew him, inside and out. I had fought by his side, talked to him, laughed with him. But, as these things often go, I am not known as a pleasant fourth year. I am only known as Ron's little sister.
I won't disregard myself; I am not ugly. However freckles and red hair are not the most beautiful things to look upon. I doubt anyone has ever stared at him the way I do. Not that he notices.
Hermione told me to move on, that it was just a crush. I tried, honestly, I did. I have dated but most relationships end quickly. I liked lots of the boys I went around with, truly, I did, but it was nothing compared to how I feel about him. It doesn't feel like just a childish crush. It is passion, fire, burning.
Dating others only provides distraction. I have smelt Amortentia, I have inhaled the scent of him. It is all I smell, now. My family is no help either. They say young love doesn't matter. I think they are just to old to remember.
All I can rely upon is my imagination. I do have daydreams, where mostly unpleasant things happen to Cho or he swoops in and saves me. Sometimes I feel like one of those useless heroines in romance novels, waiting for him ever since first year. I was silly, then. I had no one to talk to, so I stupidly took solace in an enchanted diary. He rescued me though, and forgave me.
I have a feeling that he knew that I liked him; but probably thought it would be best to ignore it. It would of been awkward, I admit, to be dating your best friend's little sister. He probably thinks, by now, that these feelings have faded. They haven't; I have just gotten better at hiding them.
I have been spending more time with him, indirectly. The DA meetings have been interesting, though slightly sickening when he fawns over Cho. I've impressed him I think, with my knowledge of spells. I hope so, anyway. Though he was probably so transfixed by Cho with her stupid silky hair and china doll features.
I settle my gaze on the Golden Trio, laughing by the fireside. I will get him, one day. I promise myself this. Because after the petty teenage love he has for Cho fades away, I'll be there. I'll always be there. Waiting in the wings and biding my time.

Indoor plants require artificial light during those dreary days and months when there isn’t enough sunlight coming in through the windows to sustain the plants. Grow lights are the best alternative to the natural light the sun provides. Let’s quickly explore what indoor gardening is.
A Brief Guide to Indoor Gardens
Houseplants used to be one or two baskets resting on a windowsill. In recent years, the practice of indoor gardens has become immensely popular. Planting and maintaining a garden indoors is the perfect solution if you live in a climate with cold winters where the ground freezes and plants can’t survive outside.
You don’t need a huge house for an indoor garden. They can fit in the smallest apartments, as long as you have the proper equipment to care for the garden. One vital tool for ensuring your indoor plants thrive is the grow light. As the name suggests, it is a light placed directly over the plants for a certain number of hours every day to provide the plant with the nutrients it would typically get from sunlight.
|Gardinator is supported by readers. We don't want to annoy you with display ads, but we do include links to products. When you buy with our links, we may earn a commission.|
How is Artificial Light Different from Sunlight?
The light emitted by the sun includes all ends of the color spectrum, but the blue light of daylight is the optimal light for photosynthesis to occur. Photosynthesis is, of course, the method of plants absorbing the carbon dioxide produced by light and turning it into plant food, which in turn produces the oxygen we need to survive.
Light is necessary for photosynthesis to occur and there isn’t enough of it in the short winter days to keep plants healthy and growing. That’s where artificial light comes in. While artificial light isn’t an exact replica of the natural light of the sun, it is close enough to give a plant the nutrients it needs to grow and blossom indoors.
Types of Grow Lights
There are four main types of artificial light for indoor gardening – incandescent bulbs, fluorescent lights, halides, and light emitting diode (LED) lights. Here is a small breakdown of each type and how they work with indoor plants:
Incandescent lights give off more heat than light. They are typically used for vines and ferns. These lights work best when paired with the natural light in a sunny room, and the plants should be kept two-feet away from the incandescent light source to avoid cooking the plants.
Fluorescent lights are most often used with vegetables and houseplants, such as African Violets. It is the most popular type of grow light with indoor gardeners because of its versatility and low price. Fluorescent lights provide heat and light but don’t get as hot as the incandescent bulbs.
Halides are generally used to light large indoor gardens or larger plants. This is because their light is more efficient (and expensive) than the other types of grow lights. Halide lights come the closest to manufacturing all the colors on the light spectrum as the sun does. However, they still lack a significant amount of red light and are therefore used as a supplement to natural sunlight.
LED lights are a relatively new option when it comes to grow lights for indoor gardening. This type of light is a great option because it doesn’t require much power to operate and can closely simulate the light given off by the sun. LED lights are the most expensive for now because the technology is still being developed.
Features to Look for in Grow Lights
There are two features that are important to look for when choosing a grow light. The first feature is wattage. The type of grow light dictates how many watts you need in a bulb. Some grow lights, such as incandescent, come in high watts. Whereas halide bulbs are lower in wattage but have a higher distance, the light can reach.
Some of the newer models of grow lights have built-in timers that automatically shut the grow light off after a pre-set amount of time has passed. This is a great feature to have because while plants can grow in continuous light, they are shown to grow better when they have a few hours of darkness. The timers are also more efficient for your energy bill and your time. If you work outside of the home, it might not be feasible for you to be available to turn the light on and off at a certain time every day.
Plants typically need between 12 and 16 hours of light – daylight or artificial light – every day. This ensures that they have the nutrients needed to grow and bloom.

9 November 2009
New data show that the balance between the airborne and the absorbed fraction of carbon dioxide has stayed approximately constant since 1850, despite emissions of carbon dioxide having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now.
This suggests that terrestrial ecosystems and the oceans have a much greater capacity to absorb CO2 than had been previously expected.

RETURN OF THE SECAUCUS SEVEN .... If you sort of enjoyed The Big Chill, then this is the "progenitor" of what The Big Chill SHOULD have been; the original recipe. Amazingly, this special, consistently-flowing, 1979-produced film, with engaging character development, does not seem extremely "dated" today, (with a refreshing absence of cell phone scenes, overplayed drug scenes, but including those "short-shorts" on the basketball & volleyball court scenes).
The production was quite advanced in its style of filming, you are mixed into the group dynamics via the unobtrusive and intimate camera work, devoid of the typical pretext, or presentation hoopla often used to force-feed viewers with some sort pre-packaged message, music, or mood set-up. Rather, simply, it's like you are a fly on the wall, and its director John Sayles lets his characters flourish in both humor and angst in a natural flow; it's almost as if the film was done in just one masterful take. Maybe it almost was. (It would be great to find out what those actors and actresses are up to now, my guess is that they largely took up interesting roles in real life decades later, not necessarily acting.) If any you are out there and link to this site, please chime in somewhere ! Director Sayles, who played one of the characters, (I won't reveal which one) went on toward critical acclaim and success in many later directorial projects.
I was fascinated with this film as originally shown with small audience draw in theaters nationally, and I tried to obtain a video copy about ten years later, as it was such a cult film, the video cost something like $40-50 to obtain then. Now, it's back into the "attainable" range. I still love this film, it is a pleasure to own the DVD, and I will enjoy it repeatedly every few years, now.
The coolest thing is, such perfection (IMHO) in filmmaking flew almost completely under the "popular" radar when it was new. If you came of age during the 70s and experienced at least a year or so of college, and got swept up in the pre-aids relationship pleasure/angst culture, (if not the politics), you'll love this "reunion" film. (Of course the reunion occurred at the end of the 70s, of characters originally meeting in the late 60s-early 70s maelstrom. Warning, filmed in peaceful rural Vermont, so don't get your heart set on scenes or glimpses of bygone New Jersey, though the characters will remind you of friends from the NE. Have a glass of wine, darken all the windows, set your phone on vibrate and enjoy getting lost in this timeless time capsule !

A world leader offered an Easter video message over the weekend filled with affirmations directed toward the Christian church that could come off sounding a bit strange to some — only because such words don't seem to be stated in such overt ways on such public stages much at all these days.
The central theme of this leader's two-minute-and-25-second address was that his nation is "a Christian country."
So who offered the inspirational message?
British Prime Minister David Cameron.
"Easter is a time for Christians to celebrate the ultimate triumph of life over death in the resurrection of Jesus," Cameron began. "And for all of us, it's a time to reflect on the part that Christianity plays in our national life."
“The church is not just a collection of beautiful, old buildings; it is a living, active force doing great works right across our country," he continued, noting how the church helps the homeless, the addicted, the suffering and the grieving.
“Across Britain, Christians don’t just talk about ‘loving thy neighbor’, they live it out in faith schools, in prisons, in community groups," Cameron noted. "And it’s for all these reasons that we should feel proud to say, ‘This is a Christian country.’ Yes, we're a nation that embraces, welcomes and accepts all faiths and none, but we are still a Christian country."
Cameron also urged his fellow citizens to speak out about the persecution of Christians around the world.

Jarryd Hayne – a former NRL celebrity – has supposedly parted with $780,000 after falling prey in a Bitcoin rip-off. The athlete, who was slammed with a jail sentence for allegedly raping a lady, was tricked by a fellow inmate.
The scammer is presently in jail after being accused of swindling $4.6 million from household and pals in a Ponzi scheme.
Conned Even Behind Bars
As reported by Day by day Mail, the individual in command of the Bitcoin fraud was Ishan Seenar Sappideen, who met Hayne within the jail of Cooma, Australia. The previous promised a big return on funding associated to the first cryptocurrency to the ex-rugby participant and different inmates. To current himself as an knowledgeable within the discipline, he claimed he had beforehand earnt almost $300 million for shoppers.
Six fellow prisoners, together with Hayne, bit the hook and transferred over $2 million between 2020 and 2022. The funds have been despatched by individuals exterior the jail into accounts managed by Sappideen because of the lack of on-line entry within the facility.
Regardless of having a settlement that protects his six-figure funding, the whereabouts of Hayne’s funds stay unknown.
Australian regulation enforcement brokers organized the switch of Sappideen to a different correctional facility following the details about his alleged fraud.
“Earlier this 12 months, CSNSW intelligence officers grew to become conscious of allegations an inmate at Cooma Correctional Centre was trying to coerce and advise fellow inmates to make transactions on the monetary markets.
The accused inmate … has since had his safety classification reviewed to allow a better stage of supervision and fewer freedom. CSNSW refers suspected felony exercise to the Police Corrections Intelligence Unit who shares intelligence with related state and federal police,” a spokeswoman added.
Hayne, who grew to become a world rugby champion with Australia in 2013, was charged with aggravated sexual assault over a lady in Newcastle in 2019. He was not too long ago discovered responsible of two counts of sexual activity with out consent and sentenced to spend at the least three years in jail.
Different Sportsmen That Turned Victims of a Crypto Rip-off
The Brazilian soccer gamers – Gustavo Scarpa, Mayke Rocha de Oliveira, and Willian Bigode – have additionally put their names on the record of athletes lured by cryptocurrency fraudsters. They collectively misplaced greater than $5 million after investing in an alleged fraudulent agency referred to as Xland.
“I’ve all the time seen silly individuals fall sufferer to pyramid schemes and scams. Discovering myself in a scenario like that’s horrible,” Scarpa regretted.
Apparently, Bigode was rumored to have a hand within the rip-off. He denied the accusations, reminding that he’s additionally a sufferer of the scheme, dropping over $3.3 million.

Prosecutor Eric J. Smith appealed the parole release of Thomas Brandon Zeller in May, and last week the Michigan Parole Board reversed its decision to release Zeller, so that it can get an updated psychological evaluation, which will delay his parole for a year. While he was already in prison for second degree murder, Zeller was convicted of assault with intent to do great bodily harm and of assaulting a prison employee. He also received 31 misconduct violations. He has been in prison 19 years. Zeller threatened to kill a female corrections employee.
The Parole Board previously granted parole to Zeller and set a release date of June 5, 2018. Macomb County Circuit Court Judge Michael Servitto put the parole on hold, pending Smith’s appeal.
Smith raised serious concerns about the prisoner’s mental health, and the mental health treatment he received, in a brief filed with the circuit court. The prisoner thought of “killing someone” so he would not have to eat with other prisoners, failed to attend scheduled health care appointments, and has mental health issues, according to his Michigan Department of Corrections Central Office File. Smith also raised concerns about a parole condition requiring mental health treatment upon release, without an indication in the record as to when, where or even if such mental health treatment will occur, or even when an assessment will be done, if at all. The recent Parole Board decision indicates an assessment will now be done.
The circuit court appeal before Judge Servitto will likely be dismissed as “moot” now that the Parole Board is no longer releasing Zeller.
“On behalf of our deceased brother, the family thanks Prosecutor Smith for all the efforts he and his team put into the appeal. We appreciate that we were kept informed of the process, and their patience with our questions since this past April,” said a grateful family member of the victim.
Macomb County Prosecutor Eric J. Smith stated, “This case shows prisoners need appropriate mental health treatment before release. The Parole Board deserves credit for reversing this parole to do a psychological review. How can we expect this prisoner to be crime free when paroled, when he has continued to be violent while in prison?”
In 1998, the crime victim was pronounced dead from multiple fatal stab wounds to his chest area. Zeller fled the scene after arguing with him over a $200 dispute. In front of eyewitnesses, Zeller threatened to stab the victim and then did exactly that. He admitted to stabbing the victim over money. At the time of the offense, the prisoner considered himself a “skin head” and claimed affiliation with an Aryan group, which affiliation he has since renounced. Zeller was sentenced to 15 – 30 years for second degree murder. He has been in prison over 18 years.
Zeller’s next parole review date is June 4, 2019.


Apple was recently rumored to be working on the successor to the Apple iPhone SE smartphone, dubbed iPhone SE 2. The handset was supposed to debut in the span of next couple of months. Numerous reports carrying the alleged specifications of the handset have surfaced online.
These reports have suggested that the smartphone will take the same design as the iPhone SE. The only difference will be regarding its specifications. However, there won’t be a lot of difference when it comes to the smartphone’s specs either. Despite the fact that there is such little difference between the upcoming smartphone and its predecessor, a new report claims that the launch might be delayed. Apple has reportedly run into some issues with government policy, which might delay the start by a couple of months at least.
Previous reports suggested that the company might introduce the smartphone at the recent Worldwide Developers Conference, which was held in February this year. However, that didn’t turn out to be true. Other reports had stated that the firm might take the wraps off the alleged iPhone SE 2 this week, during their education-based event.
Interestingly, newer sources are now suggesting that the smartphone might be manufactured in India. However, this does not change the fact that the smartphone’s launch is delayed. It goes without saying that Apple still hasn’t confirmed the news as yet. Apple has made its plans for setting up a manufacturing unit in the country for long. They have already set up a group in Bengaluru that is functional at the moment.
As far as its specifications are concerned, the smartphone will gain its power from Apple’s latest A10 processor, the same as the one that appeared in iPhone 7 and 7 Plus. It will offer 2GB of RAM along with 32GB of inbuilt memory. There will also be a 128GB option. According to a KGI analyst, Ming-Chi Kuo had claimed that the second generation iPhone SE will be a highly incremental update with just a specification bump and minimal design changes.
