description: In a homogeneous and isotropic universe with non-zero spatial curvature we consider the effects of gravitational particle production in the dynamics of the universe. We show that the dynamics of the universe in such a background is characterized by a single nonlinear differential equation which is significantly dependent on the rate of particle creation and whose solutions can be dominated by the curvature effects at early times. For different particle creation rates we apply the singularity test in order to find the analytic solutions of the background dynamics. We describe the behavior of the cosmological solutions for both open and closed universes. We also show how the effects of curvature can be produced by the presence of a second perfect fluid with an appropriate equation of state. By combining that results with the analysis of the critical points we find that our consideration can be related with the pre-inflationary era. Specifically we find that for negative spatial curvature small changes of the Milne spacetime leads to a de Sitter universe.

description: Accurate determination of the regularization parameter in inverse problems still represents an analytical challenge, owing mainly to the considerable difficulty to separate the unknown noise from the signal. We present a new approach for determining the parameter for the general-form Tikhonov regularization of linear ill-posed problems. In our approach the parameter is found by approximate minimization of the distance between the unknown noiseless data and the data reconstructed from the regularized solution. We approximate this distance by employing the Picard parameter to separate the noise from the data in the coordinate system of the generalized SVD. A simple and reliable algorithm for the estimation of the Picard parameter enables accurate implementation of the above procedure. We demonstrate the effectiveness of our method on several numerical examples. A MATLAB-based implementation of the proposed algorithms can be found at https://www.weizmann.ac.il/condmat/superc/software/

Many modifications were constructed, all based on partitions of triangles or rectangles. The fractal example of Frank and Whittaker requires 13 different types of tiles. We present an example of a single tile with fractal boundary and very simple geometric structure which has the same symmetry and spectral properties as the pinwheel triangle.

description: In Kohn-Sham electronic structure computations, wave functions have singularities at nuclear positions. Because of these singularities, plane-wave expansions give a poor approximation of the eigenfunctions. In conjunction with the use of pseudo-potentials, the PAW (projector augmented-wave) method circumvents this issue by replacing the original eigenvalue problem by a new one with the same eigenvalues but smoother eigenvectors. Here a slightly different method, called VPAW (variational PAW), is proposed and analyzed. This new method allows for a better convergence with respect to the number of plane-waves. Some numerical tests on an idealized case corroborate this efficiency.

description: In this article, a numerical analysis of the projector augmented-wave (PAW) method is presented, restricted to the case of dimension one with Dirac potentials modeling the nuclei in a periodic setting. The PAW method is widely used in electronic ab initio calculations, in conjunction with pseudopotentials. It consists in replacing the original electronic Hamiltonian $H$ by a pseudo-Hamiltonian $H^{PAW}$ via the PAW transformation acting in balls around each nuclei. Formally, the new eigenvalue problem has the same eigenvalues as $H$ and smoother eigenfunctions. In practice, the pseudo-Hamiltonian $H^{PAW}$ has to be truncated, introducing an error that is rarely analyzed. In this paper, error estimates on the lowest PAW eigenvalue are proved for the one-dimensional periodic Schrödinger operator with double Dirac potentials.

description: Ce mémoire professionnel s’inscrit dans une réflexion autour de la construction des stéréotypes de genre dans l’agencement matériel et la pratique du jeu libre dans les deux premières années du cycle 1. Bien que le jeu libre soit une activité fondamentale pour l’acquisition des gains développementaux (Bodrova & Leong, 2012), il est également un moment propice à la construction et l’émergence de stéréotypes de genre chez les élèves. Outre le jeu libre, l’espace va moduler le comportement des enfants et va contribuer au processus de construction identitaire (Direnberger & Schmoll, 2014). Dans cette recherche, nous cherchons à savoir si le jeu libre et l’agencement de la classe renforcent les stéréotypes de genre chez les élèves, en nous appuyant sur une question de recherche principale et deux sous-questions. Pour cela, nous nous basons sur des interviews d’élèves en début et en fin de semestre et sur l’observation ponctuelle en salle de classe, qui nous ont permis de réaliser que les stéréotypes de genre étaient véhiculés au travers d’interactions lors des moments de jeu. En plus des interactions, nous avons remarqué que le matériel et l’agencement de la salle de classe contribuaient également à renforcer une division sexuée des tâches et des espaces. Cette recherche permet de sensibiliser les enseignant·e·s à l’agencement de leur salle de classe et aux discours tenus par les élèves, qui mériteraient d’être discutés de manière critique avec elles·eux. Cela pour éviter que les stéréotypes deviennent des prophéties autoréalisatrices et normatives (Jacobson & Rosenthal, 1968).

description: Plants are an abundant natural source of effective antibiotic compounds. Phytomedical investigations of certain plants haven’t still been conducted. One of them is Najas minor (N. minor), an aquatic plant with confirmed allelopathy. Research conducted in this study showed the influence of water and ethyl acetate extracts of N. minor on microorganisms, in the view of chemical profiling of volatile constituents and the concentrations of total phenols, flavonoids and tannins. Antimicrobial activity was defined by determining minimum inhibitory and minimum microbicidal concentrations using microdilution method. Influence on bacterial biofilm formation was performed by tissue culture plate method. The total phenolics, flavonoids and condensed tannins were determined by Folin-Ciocalteu, aluminum chloride and butanol-HCl colorimetric methods. Chemical profiling of volatile constituents was investigated by GC and GC-MS. Water extract didn't have antimicrobial activity below 5000 µg/mL. Ethyl acetate extract has shown strong antimicrobial activity on G+ bacteria - Staphylococcus aureus PMFKGB12 and Bacillus subtilis (MIC < 78.13 µg/mL). The best antibiofilm activity was obtained on Escherichia coli ATCC25922 (BIC50 at 719 µg/mL). Water extract had higher yield. Ethyl acetate extract had a significantly greater amount of total phenolics, flavonoids and tannins. As major constituent hexahydrofarnesyl acetone was identified. The ethyl acetate extract effected only G+ bacteria, but the biofilm formation of G-bacteria was suppressed. There was a connection between those in vivo and in vitro effects against pathogenic bacterial biofilm formation. All of this points to a so far unexplored potential of N. minor.

description: This paper discusses some infinite trigonometric products which are characteristic functions of simple random walks on the real line; in fact, these define "random Riemann-$ζ$ functions," a notion which is explained. The concept of typicality for random Riemann $ζ$ functions is explained and connected to the Riemann hypothesis. Then it is shown that the distribution functions of these random walks are Schwarz functions. It is also shown that their characteristic function factors into the characteristic function of a Levy stable random variable and a subdominant fluctuating factor. As a corollary it also follows that amateur mathematician Benoit Cloitre's infinite trigonometric product $\prod_{n=1}^\infty \left[\frac23+\frac13\cos\left(\frac{x}{n^{2}}\right)\right] = e^{- C \,\sqrt{|x|} +\varepsilon(|x|)},$ with $|\varepsilon(|x|)| \leq K |x|^{1/3}$ for some $K>0$, and with $ C= \int\frac{\sinξ^2}{2+\cosξ^2}{\rm{d}}ξ;$ numerically, $C = 0.319905585... \sqrtπ$. This confirms a surmise of Benoit Cloitre. The $O\big(|x|^{1/3}\big)$ error bound is empirically found to be accurate for moderately sized $|x|$ but not for larger $|x|$. This difference $\varepsilon(|x|)$ between Cloitre's $\log \prod_{n\geq1}\left[\frac23 +\frac13\cos\left(\frac{x}{n^{2}}\right)\right]$ and its regular trend $-C\sqrt{|x|}$, although deterministic, appears to be an "empirically unpredictable" function. Our probabilistic investigation of this phenomenon connects the fluctuations to the "random Riemann-$ζ$ function with argument 2."

description: In a previous study we presented a technique to differentiate between randomly predictable and randomly unpredictable amino acid pairs. We have shown that all of 95 variants in human collagen alpha1(I) chain precursor (CA11) occurred at randomly unpredictable amino acid pairs. To study whether this is unique for the human collagen alpha1(I) chain precursor (CA11) or whether this is a more general principle we examined another human collagen precursor, the human collagen alpha1(III) chain precursor (CA13), in which 106 variants have been documented. Interestingly, all of 106 variants occurred at randomly unpredictable amino acid pairs in human CA13. In conclusion, the observation that randomly unpredictable amino acid pairs are more susceptible to variation seems to be a more general principle for human collagen chain precursor proteins.

description: All measurements are comparisons. The only physically accessible degrees of freedom (DOFs) are dimensionless ratios. The objective description of the universe as a whole thus predicts only how these ratios change collectively as one of them is changed. Here we develop a description for classical Bianchi IX cosmology implementing these relational principles. The objective evolution decouples from the volume and its expansion degree of freedom. We use the relational description to investigate both vacuum dominated and quiescent Bianchi IX cosmologies. In the vacuum dominated case the relational dynamical system predicts an infinite amount of change of the relational DOFs, in accordance with the well known chaotic behaviour of Bianchi IX. In the quiescent case the relational dynamical system evolves uniquely though the point where the decoupled scale DOFs predict the big bang/crunch. This is a non-trivial prediction of the relational description; the big bang/crunch is not the end of physics - it is instead a regular point of the relational evolution. Describing our solutions as spacetimes that satisfy Einstein's equations, we find that the relational dynamical system predicts two singular solutions of GR that are connected at the hypersurface of the singularity such that relational DOFs are continuous and the orientation of the spatial frame is inverted.

description: We explore the trap profiles of a two-dimensional atomic Fermi gas in the presence of a Rashba spin-orbit coupling and under an adiabatic rotation. We first consider a non-interacting gas and show that the competition between the effects of Rashba coupling on the local density of single-particle states and the Coriolis effects caused by rotation gives rise to a characteristic ring-shaped density profile that survives at experimentally-accessible temperatures. Furthermore, Rashba splitting of the Landau levels takes the density profiles on a ziggurat shape in the rapid-rotation limit. We then consider an interacting gas under the BCS mean-field approximation for local pairing, and study the pair-breaking mechanism that is induced by the Coriolis effects on superfluidity, where we calculate the critical rotation frequencies both for the onset of pair breaking and for the complete destruction of superfluidity in the system. In particular, by comparing the results of fully-quantum-mechanical Bogoliubov-de Gennes approach with those of semi-classical local-density approximation, we construct extensive phase diagrams for a wide-range of parameter regimes in the trap where the aforementioned competition may, e.g., favor an outer normal edge that is completely phase separated from the central superfluid core by vacuum.

description: By slight modification of the data of the Sierpinski gasket, keeping the open set condition fulfilled, we obtain self-similar sets with very dense parts, similar to fractals in nature and in random models. This is caused by a complicated structure of the open set and is revealed only under magnification. Thus the family of self-similar sets with separation condition is much richer and has higher modelling potential than usually expected. An interactive computer search for such examples and new properties for their classification are discussed.

description: Canavan disease (CD) is an autosomal recessive disorder, characterized by spongiform degeneration of the white matter of the brain. Aspartoacylase (ASPA) hydrolyses N-acetylaspartic acid to aspartate and acetate. Mutation of the gene results in enzyme deficiency to result CD. The clinical features seen in the disease are head lag, macrocephaly, hypotonia and mental retardation. More than forty five mutations have been identified in the ASPA gene. Pathophysiological abnormalities seen in CD is likely due to abnormal metabolic levels of NAA, aspartate, acetate, aspartate aminotransferase, glutamate, glutamate dehydrogenase, g-aminobutyric acid, and ketoglutarate dehydrogenase complex. These pathways are useful to understand possible therapeutical targets and pharmacological manipulations in CD.

Spontaneous orbital-selective Mott transitions and the Jahn-Teller metal of A$_3$C$_{60}$

description: The alkali-doped fullerides A$_3$C$_{60}$ are half-filled three-orbital Hubbard systems which exhibit an unconventional superconducting phase next to a Mott insulator. While the pairing is understood to arise from an effectively negative Hund coupling, the highly unusual Jahn-Teller metal near the Mott transition, featuring both localized and itinerant electrons, has not been understood. This property is consistently explained by a previously unrecognized phenomenon: the spontaneous transition of multiorbital systems with negative Hund coupling into an orbital-selective Mott state. This symmetry-broken state, which has no ordinary orbital moment, is characterized by an orbital-dependent two-body operator (the double occupancy) or an orbital-dependent kinetic energy, and may be regarded as a diagonal-order version of odd-frequency superconductivity. We propose that the recently discovered Jahn-Teller metal phase of Rb$_x$Cs$_{3-x}$C$_{60}$ is an experimental realization of this novel state of matter.

description: Statistical modelling techniques for automatic reading systems substantially rely on the availability of compact and meaningful feature representations. State-of-the-art feature extraction for offline handwriting recognition is usually based on heuristic approaches that describe either basic geometric properties or statistical distributions of raw pixel values. Working well on average, still fundamental insights into the nature of handwriting are desired. In this paper we present a novel approach for the automatic extraction of appearance-based representations of offline handwriting data. Given the framework of deep belief networks -- Restricted Boltzmann Machines -- a two-stage method for feature learning and optimization is developed. Given two standard corpora of both Arabic and Roman handwriting data it is demonstrated across script boundaries, that automatically learned features achieve recognition results comparable to state-of-the-art handcrafted features. Given these promising results the potential of feature learning for future reading systems is discussed.

description: We study the possible breakdown of quantum thermalization in a model of itinerant electrons on a one-dimensional chain without disorder, with both spin and charge degrees of freedom. The eigenstates of this model exhibit peculiar properties in the entanglement entropy, the apparent scaling of which is modified from a "volume law" to an "area law" after performing a partial, site-wise measurement on the system. These properties and others suggest that this model realizes a new, non-thermal phase of matter, known as a quantum disentangled liquid (QDL). The putative existence of this phase has striking implications for the foundations of quantum statistical mechanics.

Ground states of extended Hubbard models in the atomic limit

Subjects: subject: 510

description: The possible ground states of an extended Hubbard model in the atomic limit, augmented by an additional nearest neighbour Ising-like interaction and an external magnetic field, are rigorously determined for arbitrary values of the coupling parameters and arbitrary chemical potential. The method used requires only simple convexity arguments and the examination of all possible configurations of small clusters of lattice sites, which may be done by computer. The results are valid for all lattices ofAB type (two interpenetrating sublattices). The type of order found are ferromagnetic, antiferromagnetic, and charge density wave. Perturbation theory suggests that for finite band width there may be a state showing both a charge density wave and ferromagnetic order.

description: Given recent progress in the realization of Majorana zero modes in semiconducting nanowires with proximity-induced superconductivity, a crucial next step is to attempt an experimental demonstration of the predicted braiding statistics associated with the Majorana mode. Such a demonstration should, in principle, confirm that observed zero-bias anomalies are indeed indicative of the presence of anyonic Majorana zero modes. Moreover, such a demonstration would be a breakthrough at the level of fundamental physics: the first clear demonstration of a non-Abelian excitation. It is therefore important to clarify the expected signals of Majorana physics in the braiding context, and to differentiate these signals from those that might also arise in non-topological variants of the same system. A definitive and critical distinction between signals expected in topological (i.e. anyonic) and non-topological (i.e. trivial) situations is therefore essential for future progress in the field. In this manuscript, we carefully examine the expected signals of braiding and fusion experiments in topological and non-topological variants of the experimental nanowire systems in which Majoranas are predicted to occur. We point out situations where `trivial' and `anyonic' signatures may be similar experimentally, necessitating a certain level of caution in the interpretation of various proposed fusion and braiding experiments. We find in particular that braiding experiments consisting of full braids (two Majorana exchanges) are better at distinguishing between topological and non-topological systems than fusion experiments or experiments with an odd number of Majorana exchanges.

description: In this paper, Dirac`s equation in anisotropic Bianchi-type-I background spacetimes is treated w.r.t. orthonormal frames. By specializing to the massless spinor case and metrics with power-law scale factors and planar symmetry, an analytical expression of the approximate time evolution operator is derived. By use of this operator, all approximate spinor solutions can be generated. By construction, these solutions agree asymptotically and at early times with the exact solutions. The operator approach is also well adapted for studying the case of small deviations from conformally flat backgrounds. In particular, it can be shown that the limiting case of vanishing anisotropy renders the correct

description: Depuis quelques années, les apprentissages fondamentaux liés cycle 1 sont au cœur des préoccupations. Le Plan d’études romand, référence pour les enseignant.e.s, y a dédié un chapitre sur le sujet. De nombreuses auteures chercheuses telles que Clerc-Georgy et Duval (2020), Richard et al. (2019) Chevallier-Gaté (2014) et Marinova (2020), pour n’en citer que certaines, s’intéressent au développement des compétences socio-émotionnelles notamment par le biais du jeu de faire semblant. La place actuelle de ce jeu, au sein des classes, n’est encore que peu développée même si dans une perspective historico-culturelle, le jeu est considéré comme l’activité maîtresse de l’enfant entre 3 et 7 ans. Les bénéfices observés dans le développement des élèves ont été prouvés dans de nombreuses recherches. Dans le cadre de ce mémoire, nous avons mis en place une séquence d’enseignement sur les émotions ainsi que des moments de jeu de faire semblant dans nos classes de stages respectives. Le but étant d’observer de potentielles évolutions dans la maturité du jeu de faire semblant de nos élèves mais également une éventuelle progression dans les compétences socioémotionnelles

Analysis of signaling pathways in fibroblasts stimulated with HK1EBV cell-derived exosomes compared with those exposed to medium. The top-scoring signaling pathways were identified using Ingenuity Pathway Analysis (IPA) software (QIAGEN). The identified pathways were ranked by significance [−log (p-value)]. The number of genes that met cutoff criteria [|log2(FC)| > 0.5 and p value < 0.05] in a given signaling pathway was shown. Total RNAs were harvested 6 hours post HK1EBV cell-derived exosome (10 μg/ml) stimulation.
A security architecture for microprocessors

subject: 004

description: SAM ist eine Sicherheitsarchitektur, die aus einer Prozessorerweiterung und einem entsprechend angepassten Betriebssystem besteht. Die Prozessorerweiterung besteht primär aus einer für den Programmierer transparenten Sicherheitsschicht, die automatisch die Integrität aller geladenen Daten prüft und sämtliche Daten, die den Prozessor verlassen, verschlüsseln kann. Damit ist es selbst bei einem direkten Zugri auf den Hauptspeicher nicht möglich, ungeschützte Daten zu lesen oder zu manipulieren. Entschlüsselte Daten sind dabei nur innerhalb des Prozessors verfügbar und werden dort durch die Architektur vor unerlaubtem Zugri geschützt. Dieser Schutz schlie t auch Schutz vor privilegierten Benutzern wie Administratoren mit erweiterten Rechten ein. Weiterhin stellt SAM sicher, dass ein Programm nur auf bestimmten Prozessoren entschlüsselt werden kann und somit nur auf diesen ausführbar ist. Die Integritätssicherung wird über kryptographische Hashes erreicht. Diese ermöglichen eine überprüfung der Daten und dienen damit der Erkennung von Manipulationen. Jede vom Prozessor erkannte Manipulation führt zu einem sofortigen Programmabbruch. Somit ist sichergestellt, dass nur unmodifizierte Programme ausgeführt werden können und Manipulationen die Datensicherheit beeinträchtigen können. Der Prozessor muss verschlüsselte, gesicherte und ungesicherte (und damit auch unverschlüsselte) Speicherbereiche unterscheiden können. Bei SAM wird der Speicher dazu in einen gesicherten, einen verschlüsselten und einen ungesicherten Bereich aufgeteilt. Instruktionen, die in einem gesicherten Bereich liegen, können auf auf den gesamten Speicher zugreifen und verschlüsselte Daten werden transparent entschlüsselt. Ungesicherte Instruktionen können ebenfalls auf den gesamten Speicher zugreifen, allerdings bleiben verschlüsselte Bereiche verschlüsselt und können somit nicht analysiert werden. Das Betriebssystem basiert auf einem für SAM geringfügig angepassten Linux-Kernel. Die änderungen sind bestehen hauptsächlich aus der Anpassung hardwarenaher Funktionen des Prozessmanagements und des Multitaskings an die Sicherheitsfunktionen des Prozessors. Die Prozessorerweiterung ist als optionale Erweiterung entwickelt worden, damit normale und ungesicherte Programme parallel zu verschlüsselten Programmen ausgeführt werden können. Damit können die mit SAM gesicherten Prozessoren ebenfalls für nicht sicherheitskritische Aufgaben verwendet werden um deren Auslastung zu erhöhen. Die Umwandlung bestehender Programme in für SAM gesicherte Programme ist einfach, und erfordert nur minimale änderungen am Programmcode.
