description: Presence of lower cutoff in fiber threshold distribution may affect the failure properties of a bundle of fibers subjected to external load. We investigate this possibility both in a equal load sharing (ELS) fiber bundle model and in local load sharing (LLS) one. We show analytically that in ELS model, the critical strength gets modified due to the presence of lower cutoff and it becomes bounded by an upper limit. Although the dynamic exponents for the susceptibility and relaxation time remain unchanged, the avalanche size distribution shows a permanent deviation from the mean-fiels power law. In the LLS model, we analytically estimate the upper limit of the lower cutoff above which the bundle fails at one instant. Also the system size variation of bundle's strength and the avalanche statistics show strong dependence on the lower cutoff level.

Educational Leadership Reconceived Through the Lens of the Capability Approach of Amartya Sen and Martha Nussbaum

description: This thesis explores educational leadership reconceived through the lens of the Capability Approach as presented by Amartya Sen and Martha Nussbaum. Chapter One explains our background and our inquiry process, with our inquiry question being: How can educational leaders work with intention to motivate each staff member? Chapter Two, our literature review, first focused on analysing various theories of motivation. However, upon discovering the limitations of these theories, we found a more holistic approach in the Capability Approach (CA), which led us to focus on the importance of people, what they are able to do, to be and aspire to be, rather than in the process of simply motivating them. Chapter Three demonstrates how educational leadership, reconceived through the lens of the CA, can be used to tackle real-life scenarios in schools. Each of the six scenarios we present focuses on one of the core concepts of the CA. In exploring these concepts, we found unexpected connections to important academic scholars as they relate to core ideas we felt were important to acknowledge. These scholars’ philosophies align themselves with our interpretation of the CA. In Chapter Four, we present our six recommendations on how to effectively use the CA as an educational leader. In furthering our understanding of the CA, we observe the pressing need for educational leaders to develop empathic relationships and demonstrate support and care for staff members as educators. At the core of our research findings is the realization that educational leaders must support staff members based on their individual capabilities and functionings - which are two of the six core concepts of the CA. They must place each staff member at the forefront of decision-making. This understanding would help teachers feel noticed and valued. In Chapter Five, we reflect on what we learned from this overall experience, as expressed in the declaration of our commitments.

description: This paper develops a two gene, single fitness peak model for determining the equilibrium distribution of genotypes in a unicellular population which is capable of genetic damage repair. The first gene, denoted by $ σ_{via} $, yields a viable organism with first order growth rate constant $ k > 1 $ if it is equal to some target ``master'' sequence $ σ_{via, 0} $. The second gene, denoted by $ σ_{rep} $, yields an organism capable of genetic repair if it is equal to some target ``master'' sequence $ σ_{rep, 0} $. This model is analytically solvable in the limit of infinite sequence length, and gives an equilibrium distribution which depends on $ μ\equiv L\eps $, the product of sequence length and per base pair replication error probability, and $ \eps_r $, the probability of repair failure per base pair. The equilibrium distribution is shown to exist in one of three possible ``phases.'' In the first phase, the population is localized about the viability and repairing master sequences. As $ \eps_r $ exceeds the fraction of deleterious mutations, the population undergoes a ``repair'' catastrophe, in which the equilibrium distribution is still localized about the viability master sequence, but is spread ergodically over the sequence subspace defined by the repair gene. Below the repair catastrophe, the distribution undergoes the error catastrophe when $ μ$ exceeds $ \ln k/\eps_r $, while above the repair catastrophe, the distribution undergoes the error catastrophe when $ μ$ exceeds $ \ln k/f_{del} $, where $ f_{del} $ denotes the fraction of deleterious mutations.

description: Double-slit electron interferometers, fabricated in high mobility two-dimensional electron gas (2DEG), proved to be very powerful tools in studying coherent wave-like phenomena in mesoscopic systems. However, they suffer from small fringe visibility due to the many channels in each slit and poor sensitivity to small currents due to their open geometry. Moreover, the interferometers do not function in a high magnetic field, namely, in the quantum Hall effect (QHE) regime, since it destroys the symmetry between left and right slits. Here, we report on the fabrication and operation of a novel, single channel, two-path electron interferometer that functions in a high magnetic field. It is the first electronic analog of the well-known optical Mach-Zehnder (MZ) interferometer. Based on single edge state and closed geometry transport in the QHE regime the interferometer is highly sensitive and exhibits very high visibility (62%). However, the interference pattern decays precipitously with increasing electron temperature or energy. While we do not understand the reason for the dephasing we show, via shot noise measurement, that it is not a decoherence process that results from inelastic scattering events.

description: The nonequilibrium steady state of the one-dimensional (1D) Kardar-Parisi-Zhang (KPZ) universality class is studied in-depth by exact solutions, yet no direct experimental evidence of its characteristic statistical properties has been reported so far. This is arguably because, for an infinitely large system, infinitely long time is needed to reach such a stationary state and also to converge to the predicted universal behavior. Here we circumvent this problem in the experimental system of growing liquid-crystal turbulence, by generating an initial condition that possesses a long-range property expected for the KPZ stationary state. The resulting interface fluctuations clearly show characteristic properties of the 1D stationary KPZ interfaces, including the convergence to the Baik-Rains distribution. We also identify finite-time corrections to the KPZ scaling laws, which turn out to play a major role in the direct test of the stationary KPZ interfaces. This paves the way to explore unsolved properties of the stationary KPZ interfaces experimentally, making possible connections to nonlinear fluctuating hydrodynamics and quantum spin chains as recent studies unveiled relation to the stationary KPZ.

description: We present a deep ISO observation at 6.7 microns of the 53W002 group of galaxies and AGN at z=2.4. This approximately samples the emitted K band. The faint, blue star-forming objects are not detected, as expected from their very blue color across the emitted optical and UV. However, 53W002 itself is detected at the 3-sigma level, with an emitted V-K color appropriate for a population formed starting at z=3.6-7.0 with most likely value z=4.7. This fits with shorter-wavelength data suggesting that the more massive members of this group, which may all host AGN, began star formation earlier in deeper potential wells than the compact Lyman-alpha emission objects. Two foreground galaxies are detected, as well as several stars. One additional 6.7-micron source closely coincides with an optically faint galaxy, potentially at z=2-3. The overall source counts are consistent with other ISO deep fields.

description: One of the simplest pseudo-Hermitian models with real spectrum (viz., square-well on a real interval I of coordinates) is re-examined. A PT-symmetric complex deformation C of I is introduced and shown tractable via an innovated approach to matching conditions. The result is surprising: an arbitrarily small deformation I -> C implies a sudden collapse (i.e., the spontaneous PT-symmetry breaking) of virtually all the spectrum (i.e., up to its low-energy part).

Macroscopic boundary effects in the one-dimensional extended Bose-Hubbard model

description: We study the effect of different open boundary conditions on the insulating ground states of the one-dimensional extended Bose-Hubbard model at and near unit filling. To this end, we employ the density matrix renormalization group method with system sizes up to 250 sites. To characterize the system, various order parameters and entanglement entropies are calculated. When opposite edge potentials are added to the two ends of the chain, the inversion symmetry is explicitly broken, and the regular bulk phases appear. On the other hand, simple open boundary conditions often exhibit non-degenerate ground states with a domain wall in the middle of the chain, which induces a sign-flip of an order parameter. Such a domain wall can lead to an algebraic behavior of the off-diagonals of the single particle density matrix. We show that this algebraic behavior adds only a finite contribution to the entanglement entropy, which does not diverge as the system size increases. Therefore, it is not an indication of a superfluid phase. We confirm this picture by analytical calculations based on an effective Hamiltonian for a domain wall.

description: Transactional cloud applications such as payment, booking, reservation systems, and complex business workflows are currently being rewritten for deployment in the cloud. This migration to the cloud is happening mainly for reasons of cost and scalability. Over the years, application developers have used different migration approaches, such as microservice frameworks, actors, and stateful dataflow systems.
 The migration to the cloud has brought back data management challenges traditionally handled by database management systems. Those challenges include ensuring state consistency, maintaining durability, and managing the application lifecycle. At the same time, the shift to a distributed computing infrastructure introduced new issues, such as message delivery, task scheduling, containerization, and (auto)scaling.
 Although the data management community has made progress in developing analytical and transactional database systems, transactional cloud applications have received little attention in database research. This tutorial aims to highlight recent trends in the area and discusses open research challenges for the data management community.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.

Here, putative global minima of the potential energy have been located for these clusters for all sizes up to N<125. Although none of the usual structural forms are lowest in energy and many of the clusters have no overall order, strong structural preferences have been identified.Many of the clusters are based on distorted oblate Marks decahedra, where the distortion involves the bringing together of atoms on either side of a re-entrant groove of the Marks decahedron.

description: Gauge theory on the q-deformed two-dimensional Euclidean plane R^2_q is studied using two different approaches. We first formulate the theory using the natural algebraic structures on R^2_q, such as a covariant differential calculus, a frame of one-forms and invariant integration. We then consider a suitable star product, and introduce a natural way to implement the Seiberg-Witten map. In both approaches, gauge invariance requires a suitable ``measure'' in the action, breaking the E_q(2)-invariance. Some possibilities to avoid this conclusion using additional terms in the action are proposed.

description: We assess the most macroscopic matter-wave experiments to date as to the extent to which they probe the quantum-classical boundary by demonstrating interference of heavy molecules and cold atomic ensembles. To this end, we consider a rigorous Bayesian test protocol for a parametrized set of hypothetical modifications of quantum theory, including well-studied spontaneous collapse models, that destroy superpositions and reinstate macrorealism. The range of modification parameters ruled out by the measurement events quantifies the macroscopicity of a quantum experiment, while the shape of the posterior distribution resulting from the Bayesian update reveals how conclusive the data are at testing macrorealism. This protocol may serve as a guide for the design of future matter-wave experiments ever closer to truly macroscopic scales.

description: Το RSA είναι ένα κρυπτοσύστημα που δημιουργήθηκε το 1977. Είναι από τα πιο δημοφιλή κρυπτοσυστήματα, με ευρεία χρήση στην καθημερινότητα μας. Όμως, προκειμένου να επιτύχουν ταχεία αποκρυπτογράφηση ή για να αυξήσουν την υπολογιστική ισχύ της μηχανής αποκρυπτογράφησης, οι χρήστες του RSA επιλέγουν επισφαλείς παραμέτρους εισόδου. Έτσι, τα τελευταία χρόνια διάφοροι μελετητές ανέδειξαν διάφορους κινδύνους που προκύπτουν από την εσφαλμένη σχεδίαση του RSA και ανέπτυξαν διάφορες επιθέσεις που είναι ικανές να προσβάλλουν το RSA, βασισμένες στις επιλογές των σχεδιαστών. Στην παρούσα διπλωματική εργασία, παρουσιάζουμε την κλάση επιθέσεων στο RSA που βασίζεται στα συνεχή κλάσματα. Η αρχή για τη μελέτη της κλάσης αυτής έγινε από τον Michael J. Wiener το 1990. Από τότε και έπειτα, έχουν δημοσιευθεί πολλές εργασίες στις οποίες παρουσιάζονται επιθέσεις που εξαρτώνται από τα συνεχή κλάσματα. Στόχος μας, λοιπόν, στην παρούσα εργασία είναι να παρουσιάσουμε επιθέσεις που ανήκουν στην προαναφερθείσα κλάση, να μελετήσουμε υπό ποιες προϋποθέσεις εφαρμόζονται, το υπολογιστικό τους κόστος, αλλά και τρόπους με τους οποίους μπορούμε να τις καταπολεμήσουμε
description: RSA is a cryptosystem which was developed in 1977. It is one of the most popular cryptosystems and it is widely used in everyday life. However, entities who use RSA tend to use insecure input parameters, so as to speed up the decryption process or to increase computational power of the deciphering machine. These are some of the reasons why researchers presented some threats to RSA which are based on the choices of designers. In this present thesis, we present the continued fraction class attacks on RSA. In 1990 Michael J. Wiener was the first one who developed an attack on RSA which depends on continued fractions. After Wiener’s work, many researchers developed and published such attacks. In conclusion, the main purpose of this thesis is to present attacks of the continued fraction class, study under which conditions these attacks can be mounted, their computational cost and ways to face them

description: We study collaboration networks in terms of evolving, self-organizing bipartite graph models. We propose a model of a growing network, which combines preferential edge attachment with the bipartite structure, generic for collaboration networks. The model depends exclusively on basic properties of the network, such as the total number of collaborators and acts of collaboration, the mean size of collaborations, etc. The simplest model defined within this framework already allows us to describe many of the main topological characteristics (degree distribution, clustering coefficient, etc.) of one-mode projections of several real collaboration networks, without parameter fitting. We explain the observed dependence of the local clustering on degree and the degree--degree correlations in terms of the ``aging'' of collaborators and their physical impossibility to participate in an unlimited number of collaborations.

description: This White Paper for the CNRS IN2P3 Prospective 2020 focuses on realistic and timely situations of inflation in connection with the CMB, gravitational and particle physics, adding inter-disciplinarity and unification values within a strongly predictive physical approach. The formulation of inflation in the Ginsburg-Landau approach developed by de Vega and Sanchez [1] and by Boyanovsky, de Vega, Sanchez and Destri [2]-[4] clarifies and places inflation in the setting of the effective field theories of particle physics. In addition, it sets up a clean way to directly confront the inflationary predictions with the available and forthcoming CMB data and select a definitive model. All CMB + LSS data until now show how powerful is the Ginsburg-Landau effective theory of inflation in predicting observables in agreement with observations including the inflation energy scale and the inflaton potential, and which has much more to provide in the future. It paves the way to discoveries, new learning and understanding.

description: We argue that ferromagnetic transition metal nanoparticles with fewer than approximately 100 atoms can be described by an effective Hamiltonian with a single giant spin degree of freedom. The total spin $S$ of the effective Hamiltonian is specified by a Berry curvature Chern number that characterizes the topologically non-trivial dependence of a nanoparticle's many-electron wavefunction on magnetization orientation. The Berry curvatures and associated Chern numbers have a complex dependence on spin-orbit coupling in the nanoparticle and influence the semiclassical Landau-Liftshitz equations that describe magnetization orientation dynamics.

description: We propose to utilize density-density correlations in the image of an expanding gas cloud to probe complex many body states of trapped ultra-cold atoms. In particular we show how this technique can be used to detect superfluidity of fermionic gases and reveal broken spin symmetries in Mott-states of atoms in optical lattices. The feasibility of the method is investigated by analysis of the relevant signal to noise ratio including experimental imperfections.

description: Non-rotating black holes in three and four dimensions are shown to possess a canonical entropy obeying the Bekenstein-Hawking area law together with a leading correction (for large horizon areas) given by the logarithm of the area with a {\it universal} finite negative coefficient, provided one assumes that the quantum black hole mass spectrum has a power law relation with the quantum area spectrum found in Non-perturbative Canonical Quantum General Relativity. The thermal instability associated with asymptotically flat black holes appears in the appropriate domain for the index characterising this power law relation, where the canonical entropy (free energy) is seen to turn complex.

description: In this thesis, we refer to the fundamental definitions of the polynomial matrices, the euclidean division among them, as well as to the left generalized inverse matrix. Moreover, we mention to the multivariate systems briefly and present an algorithm for the computation of a proper internally stabilizing and denominator (pole) assigning compensator that can be calculated via a simple formula which involves an easily calculated special form of a left generalized inverse of the right numerator of matrix fraction description. We present the computation algorithm steps thoroughly along with characteristic examples. Additionally, we demonstrate the GUI implementation in MATLAB as well as the study limitations and future work. Finally, we added the MATLAB code that we created and used in Appendix

Constraints on primordial gravitational waves from the Cosmic Microwave Background

description: Searches for primordial gravitational waves have resulted in constraints in a large frequency range from a variety of sources. The standard Cosmic Microwave Background (CMB) technique is to parameterise the tensor power spectrum in terms of the tensor-to-scalar ratio, $r$, and spectral index, $n_{\rm t}$, and constrain these using measurements of the temperature and polarization power spectra. Another method, applicable to modes well inside the cosmological horizon at recombination, uses the shortwave approximation, under which gravitational waves behave as an effective neutrino species. In this paper we give model-independent CMB constraints on the energy density of gravitational waves, $Ω_\textrm{gw} h^2$, for the entire range of observable frequencies. On large scales, $f \lesssim 10^{-16}\, \text{Hz}$, we reconstruct the initial tensor power spectrum in logarithmic frequency bins, finding maximal sensitivity for scales close to the horizon size at recombination. On small scales, $f \gtrsim10^{-15}\,\mbox{Hz}$, we use the shortwave approximation, finding $Ω_\textrm{gw} h^2 < 1.7 \times10^{-6}$ for adiabatic initial conditions and $Ω_\textrm{gw} h^2 < 2.9 \times10^{-7}$ for homogeneous initial conditions (both $2σ$ upper limits). For scales close to the horizon size at recombination, we use second-order perturbation theory to calculate the back-reaction from gravitational waves, finding $Ω_\textrm{gw} h^2 < 8.4 \times10^{-7}$, in the absence of neutrino anisotropic stress and $Ω_\textrm{gw} h^2 < 8.6 \times10^{-7}$ when including neutrino anisotropic stress. These constraints are valid for $ 10^{-15}\, \text{Hz} \gtrsim f \gtrsim 3 \times 10^{-16}\, \text{Hz}$.
