Former ou déformer: la pédagogie noire en France au XIXe siècle
Creators: name: Wallace, David Jeremy
Publisher: name: University of British Columbia
Year: 2009

description: Inspired by the work of the Swiss psychotherapist Alice Miller (For Your Own Good, 1983) on the negative effects of traditional childrearing practices in Germany, this thesis posits the existence in France of a similar tradition of "poisonous pedagogy," also founded on a set of moral principles and pedagogical techniques designed to desensitize, demoralize, and blame the child while protecting the parent/teacher. Working under the banner of Cultural Studies, I study examples of pedagogical discourse taken from a variety of cultural productions, ranging from moral treatises (lay and religious) and books on infant care (puericulture) to children's stories, primary school readers, and civics texts. Drawing on Michel Foucault's paradigms of power/knowledge and the "archeology" of knowledge, this study focusses on the various constructions of the child in nineteenth-century France. Beginning with an analysis of Jean-Jacques Rousseau's influential Emile ou de l’education (1762), this study traces the legacy of poisonous pedagogy in France during the July Monarchy, the Second Empire and the Third Republic. During the nineteenth century the discourse on children was in constant mutation, and opposing perspectives clashed throughout the century, although criticism of poisonous pedagogy became strong only in the last quarter of the century during the Third Republic. Child advocates at this time can be found in many different spheres-education, politics, medicine-but the contribution of literary writers to the discourse on children is perhaps the most dramatic of any group. The harshest criticisms of poisonous pedagogy and its concomitant construction of the child came at the end of the century in the form of two literary works: Jules Valles's L'Enfant (1879), and Jules Renard's Poil de Carotte (1894). By skillfully weaving powerful attacks on the techniques and principles of poisonous pedagogy into their texts, these two writers prefigure the pedagogical discourse of modern-day psychologists and child specialists.

description: We aim to search for the connection between the spacetime with an invariant minimum speed so-called Symmetrical Special Relativity (SSR) with Lorentz violation and the Gravitational Bose Einstein Condensate (GBEC) as the central core of a star of gravitational vacuum (gravastar), where one normally introduces a cosmological constant for representing an anti-gravity. This usual model of gravastar with an equation of state (EOS) for vacuum energy inside the core will be generalized for many modes of vacuum (dark energy star) in order to circumvent the embarrassment generated by the horizon singularity as the final stage of a gravitational collapse. In the place of the problem of a singularity of an event horizon, we introduce a phase transition between gravity and anti-gravity before reaching the Schwarzschild (divergent) radius $R_S$ for a given coexistence radius $R_{coexistence}$ slightly larger than $R_S$ and slightly smaller than the core radius $R_{core}$ of GBEC, where the metric of the repulsive sector (core of GBEC) would diverge for $r=R_{core}$, so that for such a given radius of phase coexistence $R_S

description: We investigate the effects of fuzzy measurements on spin entanglement for identical particles, both fermions and bosons. We first consider an ideal measurement apparatus and define operators that detect the symmetry of the spatial and spin part of the density matrix as a function of particle distance. Then, moving on to realistic devices that can only detect the position of the particle to within a certain spread, it was surprisingly found that the entanglement between particles increases with the broadening of detection.

In the high-energy approach analytical expressions for elastic and inelastic scattering amplitudes are obtained where all the orders in the deformation parameters are included. The multistep effect of the 2$^+$ rotational state excitation on elastic scattering is analyzed. Calculations of inelastic cross sections for the $^{17}$O ions scattered on different nuclei at about hundred Mev/nucleon are compared with experimental data, and important role of the Coulomb excitation is established.

description: We consider the transverse-momentum (q_T) distribution of generic high-mass systems (lepton pairs, vector bosons, Higgs particles, ....) produced in hadron collisions. At small q_T, we concentrate on the all-order resummation of the logarithmically-enhanced contributions in QCD perturbation theory. We elaborate on the $b$-space resummation formalism and introduce some novel features: the large logarithmic contributions are systematically exponentiated in a process-independent form and, after integration over q_T, they are constrained by perturbative unitarity to give a vanishing contribution to the total cross section. At intermediate and large q_T, resummation is consistently combined with fixed-order perturbative results, to obtain predictions with uniform theoretical accuracy over the entire range of transverse momenta. The formalism is applied to Standard Model Higgs boson production at LHC energies. We combine the most advanced perturbative information available at present for this process: resummation up to next-to-next-to-leading logarithmic accuracy and fixed-order perturbation theory up to next-to-leading order. The results show a high stability with respect to perturbative QCD uncertainties.

description: We report muon spin rotation ($μ$SR) experiments together with first-principles calculations on microscopic properties of superconductivity in the kagome superconductor LaRu$_3$Si$_2$ with $T_{\rm c}$ ${\simeq}$ 7K. We find that the calculated normal state band structure features a kagome flat band and Dirac as well as van Hove points formed by the Ru-$dz^2$ orbitals near the Fermi level. Below $T_{\rm c}$, $μ$SR reveals isotropic type-II superconductivity, which is robust against hydrostatic pressure up to 2 GPa. Intriguingly, the ratio 2$Δ/k_{\rm B}T_{\rm c}$ ${\simeq}$ 4.3 (where $Δ$ is the superconducting energy gap) is in the strong coupling limit, and $T_{\rm c}$/$λ_{eff}^{-2}$ (where $λ$ is the penetration depth) is comparable to that of high-temperature unconventional superconductors. We also find that electron-phonon coupling alone can only reproduce small fraction of $T_{\rm c}$ from calculations, which suggests other factors in enhancing $T_{\rm c}$ such as the correlation effect from the kagome flat band, the van Hove point on the kagome lattice, and high density of states from narrow kagome bands. Our experiments and calculations taken together point to strong coupling and the unconventional nature of kagome superconductivity in LaRu$_3$Si$_2$.

Linear instability of planar shear banded flow of both diffusive and non-diffusive Johnson-Segalman fluids

description: We consider the linear stability of shear banded planar Couette flow of the Johnson-Segalman fluid, with and without the addition of stress diffusion to regularise the equations. In particular, we investigate the effect of two-dimensional perturbations representing undulations along the interface between shear bands. We demonstrate analytically that, for the linear stability problem, the limit in which diffusion tends to zero is mathematically equivalent to a pure (non-diffusive) Johnson-Segalman model with a material interface between the shear bands, provided the wavelength of perturbations being considered is long relative to the (short) diffusion lengthscale. For no diffusion, we find that the flow is unstable to long waves for almost all arrangements of the two shear bands. Weak diffusion provides a small stabilising effect, rendering extremely long waves marginally stable. However, the basic long-wave instability mechanism is not affected by this, and where there would be instability as wavenumber k tends to 0 in the absence of diffusion, we observe instability for moderate to long waves even with diffusion. This paper is the first full analytical investigation into an instability first documented in the numerical study of Physical Review Letters 95 (2005) 134501 cond-mat/0501518. We discuss the relevance of this work to recent experimental observations of complex dynamics seen in shear-banded flows.

Se Serao morì poi nel 1927, troppo presto per prendere una posizione definitiva, si sa bene che a moltissimi altri scrittori essere un po’ e anche parecchio fascisti non costò per niente. E si sa pure che il loro assoggettamento era importante per il dittatore, già giornalista e (almeno nelle aspirazioni) uomo di cultura, tendente – osserva Sciascia nel Teatro della memoria – a governare l’Italia «come un redattore-capo»: attento dunque – oltre che a filtrare o snaturare le notizie – a imbrigliare le voci autorevoli, fagocitando la classe intellettuale esistente, formandone una nuova, e controllando tutti i canali di espressione, dalle accademie alla stampa, dal teatro alla produzione libraria.

description: The total organic carbon (TOC) concentration of particulate samples is a key parameter to characterize soils and sediments. To demonstrate the applicability and reliability of a modified sample preparation method for the direct measurement of TOC contents in suspended particulate samples, we analyzed five certified reference materials (CRMs) with varying TOC concentrations using a Shimadzu TOC-L CPH analyzer. Measured values were calibrated with a multi-point curve that cover the full range of the expected TOC concentrations and the results were validated using statistical values and measures. The method validation reveals that the measurements are accurate and precise for CRMs from marine and soil contexts, but show a low accuracy for the CRM containing polycyclic aromatic hydrocarbons (PAHs). This demonstrates the applicability and reliability of the modified preparation method for direct TOC determination of suspended particulate samples. Therefore, it is relevant for a broader community, beyond geosciences, and for users employing devices of other manufacturers to analyze TOC in suspended particulate samples. • Modified preparation method uses reduced sample weights and yields accurate and precise results. • Cost-efficient and environmentally friendly alternative: reduces waste by saving acid and ultrapure water. • Avoids incomplete dissolution of dolomite by heating acidified samples.

description: Models involving an interaction between the Dark Matter and the Dark Energy sectors have been proposed to alleviate the long standing Hubble constant tension. In this paper we analyze whether the constraints and potential hints obtained for these interacting models remain unchanged when using simulated Planck data. Interestingly, our simulations indicate that a dangerous fake detection for a non-zero interaction among the Dark Matter and the Dark Energy fluids could arise when dealing with current CMB Planck measurements alone. The very same hypothesis is tested against future CMB observations, finding that only cosmic variance limited polarization experiments, such as PICO or PRISM, could be able to break the existing parameter degeneracies and provide reliable cosmological constraints. This paper underlines the extreme importance of confronting the results arising from data analyses with those obtained with simulations when extracting cosmological limits within exotic cosmological scenarios.

description: Digital twins enable simulation, comprehensive analysis and predictions, as virtual representations of physical systems. They are also finding increasing interest and application in the healthcare sector, with a particular focus on digital twins of the brain. We discuss how digital twins in neuroscience enable the modeling of brain functions and pathology as they offer an in-silico approach to studying the brain and illustrating the complex relationships between brain network dynamics and related functions. To showcase the capabilities of digital twinning in neuroscience we demonstrate how the impact of brain tumors on the brain’s physical structures and functioning can be modeled in relation to the philosophical concept of plasticity. Against this technically derived backdrop, which assumes that the brain’s nonlinear behavior toward improvement and repair can be modeled and predicted based on MRI data, we further explore the philosophical insights of Catherine Malabou. Malabou emphasizes the brain’s dual capacity for adaptive and destructive plasticity. We will discuss in how far Malabou’s ideas provide a more holistic theoretical framework for understanding how digital twins can model the brain’s response to injury and pathology, embracing Malabou’s concept of both adaptive and destructive plasticity which provides a framework to address such yet incomputable aspects of neuroscience and the sometimes seemingly unfavorable dynamics of neuroplasticity helping to bridge the gap between theoretical research and clinical practice.
Galaxy Concentrations are Trimodal

description: We have analysed the distribution of inclination-corrected galaxy concentrations in the Sloan Digital Sky Survey. We find that unlike most galaxy properties, which are distributed bimodally, the distribution of concentrations is trimodal: it exhibits three distinct peaks. The newly-discovered intermediate peak, which consists of early-type spirals and lenticulars, may contain ~60% of the number density and ~50% of the luminosity density of M_r < -17 galaxies in the local universe. These galaxies are generally red and quiescent, although the distribution contains a tail of blue star-forming galaxies and also shows evidence of dust. The intermediate-type galaxies have higher apparent ellipticities than either disc or elliptical galaxies, most likely because some of the face-on intermediate types are misidentified as ellipticals. Their physical half-light radii are smaller than the radii of either the disc or elliptical galaxies, which may be evidence that they form from disc fading. The existence of a distinct peak in parameter space associated with early-type spiral galaxies and lenticulars implies that they have a distinct formation mechanism and are not simply the smooth transition between disc-dominated and spheroid-dominated galaxies.

Nanohertz gravitational waves from NEC violation in the early universe

description: We study nanohertz gravitational waves relevant to pulsar timing array experiments from quantum fluctuations in the early universe with null energy condition (NEC) violation. The NEC violation admits accelerated expansion with the scale factor $a\propto (-t)^{-p}$ ($p>0$), which gives the tensor spectral index $n_t=2/(p+1)>0$. To evade the constraint from Big Bang nucleosynthesis (BBN), we connect the NEC-violating phase to a subsequent short slow-roll inflationary phase which ends with standard reheating, and thereby reduce the high frequency part of the spectrum. An explicit model is constructed within the cubic Horndeski theory which allows for stable violation of the NEC. We present numerical examples of the background evolution having the different maximal Hubble parameters (which determine the peak amplitude of gravitational waves), the different inflationary Hubble parameters (which determine the amplitudes of high frequency gravitational waves), and different durations of the inflationary phase (which essentially determine the peak frequency of the spectrum). We display the spectra with $n_t=0.8$, $0.9$, and $0.95$ for $f\lesssim 1/{\rm yr}$, which are consistent with the recent NANOGrav result. We also check that they do not contradict the BBN constraint. We discuss how the nearly scale-invariant spectrum of curvature perturbations is produced in the NEC-violating phase.

Here we describe the rationale and initial results from a detailed spectroscopic study of three Galactic PNe undertaken with the VLT FLAMES integral-field unit spectrograph, which advances our knowledge about the small-scale physical properties, chemical abundances and velocity structure of these objects across a two-dimensional field of view, and opens up for exploration an uncharted territory in the study and modelling of PNe and photoionized nebulae in general.

description: The quasi-particle model of quark gluon plasma (QGP) is revisited here with thermodynamically consistent formalism, different from earlier studies, without the need of temperature dependent bag constant as well as other effects such as confinement effects, effective degrees of freedom etc. Our model has only one system dependent parameter and surpraisingly good fit to lattice results for gluon plasma, 2-flavor and 3-flavor QGP are obtained. The basic idea is to evaluate energy density $ε$ first from grand partition function of quasi-particle QGP and then derive all other thermodynamic functions from $ε$. Quasi-particles are assumed to have temperature dependent mass equal to plasma frequency. Energy density, pressure and speed of sound are evaluated and compared with available lattice data. We further extend the model to finite chemical potential, without any new parameters, to obtain quark density, quark susceptibility etc. and fits very well with the lattice results on 2-flavor QGP.

description: We extend and generalise the string corrections to the EM memory to the Type I superstring including spin effects. Very much as in the simpler bosonic string context, the relevant corrections are non-perturbative in $α'$, slowly decaying (as $1/R$) at large distances and modulated in retarded time $u=t-R$. For spin $N$ states in the first Regge trajectory they entail a sequence of $N$ derivatives wrt $u$ on the `parent' $N=0$ amplitude. We also briefly discuss how to include loop effects, that broaden and shift the string resonances, and how to modify our analysis for macroscopic semi-classical quasi-BPS coherent states, whose collisions may lead to detectable string memory signals in viable Type I models.

Fitting to Delta E ~ L^theta, where L is the system size, we obtain: theta = -1.54 (d=2), theta = -1.04 (d=3), theta = -0.67 (d=4) and theta = -0.37 (d=5). These results show that the lower critical dimension, d_l (the dimension where theta changes sign), is significantly higher for m=infinity than for finite m (where 2 < d_l < 3).

Proteolytic processing and membrane association of tomato ringspot nepovirus rna-1-encoded proteins
Creators: name: Wang, Aiming
Publisher: name: University of British Columbia
Year: 2009

description: Tomato ringspot nepovirus (TomRSV) encapsidates a bipartite, messenger sense RNA genome. RNA-1 is likely to encode all the viral proteins required for RNA replication. The expression and processing strategies of the RNA-1-encoded polyprotein (PI) were studied. It was found that PI is intramolecularly proteolytically processed by a virus-encoded protease at five cleavage sites to release six end products, i.e. XI, X2, NTB, VPg, Pro and Pol. All PI cleavage sites were identified. The genomic organization of TomRSV RNA-1 is distinct from that of the closely related comoviruses and of other nepoviruses. In TomRSV, two mature proteins (XI and X2) are released from the region upstream of NTB whereas only one mature protein is released from the corresponding region in all other characterized nepo- and comoviruses. Viral RNA replication is thought to be carried out by a replication complex which is secured on cellular membranes by a virus-encoded protein. To test if the NTB-VPg protein which contains a predicted trans-membrane domain is the anchor protein, association of this protein with microsomal membranes was studied in vitro. It was found that the NTB-VPg protein is an integral membrane protein and that the predicted transmembrane domain at the C-terminus of NTB is required for the membrane-association. The association of the NTB-VPg protein with microsomal membranes results in the generation of glycosylated and signal peptidase-processed proteins. The importance of these modifications for viral RNA replication needs to be elucidated. The molecular variability of the RNA-1-encoded replication-related viral proteins including VPg, Pro and Pol, and of the RNA-2-encoded coat protein among five TomRSV isolates was studied. It was found that the nucleotide sequences and the deduced amino acid sequences of RNA-1 were more conserved than those of RNA-2. Amino acid substitutions were not found in all conserved motifs identified previously in the protease and polymerase domains. Furthermore, the VPg amino acid sequence was identical in all isolates studied despite some variations at the nucleotide sequence level. The above results are discussed in light of the possible strategies for processing of the PI polyprotein and for the formation of the replication complex on cellular membranes.

description: The purpose of this note is to provide yet another example of the link between certain conformal geometries and ordinary differential equations, along the lines of the examples discussed by Nurowski in math.DG/0406400. In this particular case, I consider the equivalence problem for 3-plane fields D on 6-manifolds M that satisfy the nondegeneracy condition that D+[D,D]=TM I give a solution of the equivalence problem for such D (as Tanaka has previously), showing that it defines a so(4,3)-valued Cartan connection on a principal right H-bundle over M where H is the subgroup of SO(4,3) that stabilizes a null 3-plane in R^{4,3}. Along the way, I observe that there is associated to each such D a canonical conformal structure of split type on M, one that depends on two derivatives of the plane field D. I show how the primary curvature tensor of the Cartan connection associated to the equivalence problem for D can be interpreted as the Weyl curvature of the associated conformal structure and, moreover, show that the split conformal structures in dimension~6 that arise in this fashion are exactly the ones whose so(4,4)-valued Cartan connection admits a reduction to a spin(4,3)-connection. I also discuss how this case has features that are analogous to those of Nurowski's examples.

description: A mathematical framework is developed for the analysis of causal fermion systems in the infinite-dimensional setting. It is shown that the regular spacetime point operators form a Banach manifold endowed with a canonical Fréchet-smooth Riemannian metric. The so-called expedient differential calculus is introduced with the purpose of treating derivatives of functions on Banach spaces which are differentiable only in certain directions. A chain rule is proven for Hölder continuous functions which are differentiable on expedient subspaces. These results are made applicable to causal fermion systems by proving that the causal Lagrangian is Hölder continuous. Moreover, Hölder continuity is analyzed for the integrated causal Lagrangian.

description: Tra Otto e Novecento, lo sviluppo della critica letteraria italiana ha spesso manifestato un forte legame con l’identità nazionale e un’intensa relazione con le vicende politiche, sociali e civili del Paese. Pur tra molte differenze, da De Sanctis a Gramsci, fino ai critici militanti del secondo Novecento, il discorso sulla letteratura è stato anche un discorso sulla nazione e sulla società; il critico è stato anche un intellettuale organico, che ha visto però, nel corso dei decenni e fino a oggi, ridursi fino quasi all’esaurimento lo spazio e l’autorità necessari al proprio impegno.

description: The analysis of extremes in climate models is hindered by the lack of statistics due to the computational costs required to run simulations long enough to sample rare events. We demonstrate how rare event algorithms can improve the statistics of extreme events in state-of-the-art climate models. We study extreme warm summers and heatwaves over France and Scandinavia with CESM1.2.2 in present-day climate. The algorithm concentrates the simulations on events of importance, and shifts the probability distributions of regional temperatures such that warm summers become common. We estimate return times of extremes orders of magnitude larger than what feasible with direct sampling, and we compute statistically significant composite maps of dynamical quantities conditional on the occurence of the extremes. We show that extreme warm summers are associated to wavenumber 3 hemispheric teleconnection patterns, and that the most extreme summers are related to the succession of rare subseasonal heatwaves.

Entre femmes et jeunes filles : le roman pour adolescentes en France et au Québec
Creators: name: Di Cecco, Daniela Pamela
Publisher: name: University of British Columbia
Year: 2009

description: Novels destined for adolescents are generally aimed at a gender specific audience, the sex of the main character often determining that of the intended reader. The modern concept of adolescence is essentially based on male images of independence and restlessness, and these remain in conflict with what is still regarded as acceptable <> behaviour. Based on the premisses that both adolescence and gender are social constructs, this study aims to explore the representation and construction of female adolescence in contemporary novels for young adults in France and Quebec. My primary corpus is comprised of novels published since 1985, written by women and aimed specifically at adolescent girls. I refer to recent North American sociological and psychological studies of teenage girls to examine the relationship between the cultural context within which the novels are written and received, the literary form adopted, and the construction of a gendered identity for both author and reader. This study is divided into two parts. The first two chapters present a chronological overview of novels for adolescent girls in France and Quebec from the 193 0s to the present. In Chapter One, the novel of adolescence for adults, which preceded the first series published for young girls, provides a point of departure to examine fictional representations of adolescence. A discussion of the novel <> and the similarities between popular romance fiction and young adult series leads to a closer look at novels for adolescent girls as a branch of consumer literature. Chapter Two discusses contemporary trends in young adult fiction. Leaving behind the didactic approach that characterized earlier novels, whose main function was to prepare teenagers for their future role as responsible citizens, the contemporary novel plays a more therapeutic role, reassuring readers that they are not alone in their struggle towards adulthood. Using a corpus of about forty novels (published between 1985 and 1995), I examine publishing practices, editorial constraints and the paratext, linking the specificity of French and Quebecois novels to broader cultural differences. The second half of the thesis concentrates on a smaller sample of novels and looks at the text as a communicative tool between two generations of women. Chapter Three analyses the mother-daughter relationship in the novels, which often echoes the maternal relationship established between author and reader, and may also be reflected in the narrative structure and form. Chapter Four continues the discussion of the transmission of values from women to adolescent girls, providing an analysis of the tensions between sexuality, femininity and feminism.

description: The Innovate4Cities Conference 2021 brought together a global collection of scientists, policymakers, academics and citizen voices. The conference sought to address gaps in global knowledge and innovation, how and why to take action on climate change, and enable partnership building and collaboration while setting the stage for COP26. This report summarises the Innovate4Cities Conference 2021 and outlines key messages, whilst identifying knowledge gaps and offering areas for further research. Subsequent recommendations integrate general observations and context-specific case studies with the intention of mobilising multi-tiered climate action. The report was produced by a team of 32 students who attended the conference, rapporteured, and synthesised key messages.

description: Understanding charging mechanisms and charge retention dynamics of nanocrystal memory devices is important in optimization of device design. Capacitance spectroscopy on PECVD grown germanium nanocrystals embedded in a silicon oxide matrix was performed. Dynamic measurements of discharge dynamics are carried out. Charge decay is modelled by assuming storage of carriers in the ground states of nanocrystals and that the decay is dominated by direct tunnelling. Discharge rates are calculated using the theoretical model for different nanocrystal sizes and densities and are compared with experimental data. Experimental results agree well with the proposed model and suggest that charge is indeed stored in the quantized energy levels of the nanocrystals.

description: We present the results of direct numerical simulations of heavy particle transport in homogeneous, isotropic, fully developed turbulence, up to resolution $512^3$ ($R_λ\approx 185$). Following the trajectories of up to 120 million particles with Stokes numbers, $St$, in the range from 0.16 to 3.5 we are able to characterize in full detail the statistics of particle acceleration. We show that: ({\it i}) The root-mean-squared acceleration $a_{\rm rms}$ sharply falls off from the fluid tracer value already at quite small Stokes numbers; ({\it ii}) At a given $St$ the normalised acceleration $a_{\rm rms}/(ε^3/ν)^{1/4}$ increases with $R_λ$ consistently with the trend observed for fluid tracers; ({\it iii}) The tails of the probability density function of the normalised acceleration $a/a_{\rm rms}$ decrease with $St$. Two concurrent mechanisms lead to the above results: preferential concentration of particles, very effective at small $St$, and filtering induced by the particle response time, that takes over at larger $St$.

description: Event shapes have long been used to extract information about hadronic final states and the properties of QCD, such as particle spin and the running coupling. Recently, a family of event shapes, the angularities, has been introduced that depends on a continuous parameter. This additional parameter-dependence further extends the versatility of event shapes. It provides a handle on nonperturbative power corrections, on non-global logarithms, and on the flow of color in the final state.

description: Spinless fermions on highly frustrated lattices are characterized by a lowest single-particle band which is completely flat. Concrete realizations are provided by the sawtooth chain and the kagome lattice. For these models a real-space picture is given in terms of localized states. Furthermore, we find a finite zero-temperature entropy for a suitable choice of the chemical potential. The entropy is computed numerically at finite temperature and one observes a strong cooling effect during adiabatic changes of the chemical potential. We argue that the localized states, the associated zero-temperature entropy and thus also the large temperature variations carry over to the repulsive Hubbard model. The relation to flat-band ferromagnetism is also discussed briefly.
