description: We study ground state properties of spinless, quasi one-dimensional bosons which are confined in a harmonic trap and interact via repulsive delta-potentials. We use the exact diagonalization method to analyze the pair correlation function, as well as the density, the momentum distribution, different contributions to the energy and the population of single-particle orbitals in the whole interaction regime. In particular, we are able to trace the fascinating transition from bosonic to fermi-like behavior in characteristic features of the momentum distribution which is accessible to experiments. Our calculations yield quantitative measures for the interaction strength limiting the mean-field regime on one side and the Tonks-Girardeau regime on the other side of an intermediate regime.

description: Η παρούσα διπλωματική εργασία έχει σκοπό αφενός την μελέτη των ερμηνευτικών Σειρών στην πορεία του χρόνου, ως ερμηνευτικό εργαλείο για την μελέτη της Αγίας Γραφής και αφετέρου τον σχεδιασμό και την κατασκευή ενός διαδικτυακού εργαλείου μέσα από το οποίο θα αναβιώσει το λογοτεχνικό αυτό είδος σε ψηφιακή μορφή. Για την πραγματοποίηση του διαδικτυακού αυτού εργαλείου κατασκευάστηκε μια βάση δεδομένων μεγάλων διαστάσεων στην οποία εμπεριέχεται όλο το κείμενο της Αγίας Γραφής στην ελληνική γλώσσα, με προοπτική να περιλάβει το κείμενό της και σε άλλες γλώσσες, οργανωμένο και δομημένο σύμφωνα με τις απαιτήσεις και τους κανόνες μιας βάσης δεδομένων. Το κείμενο αυτό συνδυάστηκε με την ελληνική έκδοση Patrologia Graeca του JP Migne (Αθήνα 1985) μέσω ενός εκτενούς καταλόγου αναφορών των πατερικών κειμένων στην Βίβλο, που καταρτίσθηκε από τους καθηγητές Στέργιο Σάκκο και Παυσανία Κουτλεμάνη. Έχοντας αποτυπώσει ψηφιακά τόσο την Αγία Γραφή όσο και την Πατρολογία, καθίσταται δυνατό να δημιουργηθεί μια ψηφιακή catena, όπου ο διαδικτυακός αναγνώστης θα έχει την δυνατότητα να βλέπει για κάθε αγιογραφικό στίχο όλες τις πατερικές αναφορές σε αυτόν μαζί με το πατερικό κείμενο.
description: This dissertation aims to the study of the Catenae throughout the years as an exegetical tool of the Bible and to the design of an online tool which will revive this ancient literary genre in a digital form. For the creation of the online tool a large digital database has been built. It comprises the whole text of the Bible in Greek, with the prospect of including many more languages in the future, and the text of the Greek edition of PG by J.P Migne, organized according to the rules of a database. The two texts are conneted together through long lists of the biblical references in the patristic works, which have been compiled by the two professors of the New Testament from the Aristotle University of Thessaloniki, Stergios Sakkos and Pausanias Koutlemanis on the occasion of PG’s Athens edition (1985). This combination offers the possibility to create a digital catena which the online reader can browse and read all the relevant patristic texts annotated to every single Bible verse. Moreover, since PG is already digitally cited on the internet (http://phoenix.reltech.org/Ebind/docs/Migne/Migne.html) appropriate links have been set up in order that the full patristic text will be available to teh reader. The database has been designed with the prospect of including the patristic texts in other languages as well and with links to critical editions, like Sources Chretiennes and Corpus Christianorum.

Assessing the GABA shift hypothesis through markers for oxidative stress, neuronal activity and microglia number following early VPA exposure
Creators: name: Gifford, Janace
Publisher: name: No Publisher Supplied
Year: 2021

description: The GABA-shift hypothesis proposes that GABA agonist action is excitatory early in development and transitions to an inhibitory role later in life. The present studies assessed the GABA-shift hypothesis in three distinct ways. First, if GABA is excitatory early in life, then administration of a GABA agonist should exert excitotoxic damage mediated by oxidative stress. Accordingly, valproic acid (VPA), an indirect-acting GABA agonist, was administered early in life or to adult mice and nuclear factor erythroid 2- related factor 2 (NRF2) expression was assessed. Activation of NRF2 initiates downstream antioxidant defense mechanisms. NRF2 activation was observed only in the young (prenatal and early postnatal) VPA-treated animals compared to young saline-treated controls and adult mice treated with VPA or saline. These observations support the hypothesis that VPA exerts excitatory effects mediated by oxidative stress only in young mice. The second objective of this study was to examine cFos expression before and after the GABA shift following exposure to VPA. cFos expression is considered a measure of cell activation so, once again, its activation was expected only in the younger mice. Here we observed no strong effect of early postnatal VPA treatment on c-fos expression. Upon review of the literature it was concluded that c-Fos may not be the best measure of neuronal activation in young mice. The third objective of the present study was to examine microglia number in distinct brain areas following early VPA exposure. Microglia number was observed 24 hours following treatment with VPA or saline. There was a differential response of microglia following VPA treatment throughout development and in distinct brain areas. More microglia cells were observed in the cerebellum following VPA treatment on P7, P14 and P30. In the hippocampus, increased microglia number was observed following VPA exposure at P7 but not later time points. These studies provide evidence of neurotoxic action of VPA potentially mediated by excitotoxicity. These results elucidate the critical importance and timing of GABA development as it might relate to the effects of GABA alterations and oxidative stress during early development.

description: Motivated by current interest in disordered systems of interacting electrons, the effectiveness of the geometrically averaged density of states, $ρ_g(ω)$, as an order parameter for the Anderson transition is examined. In the context of finite-size systems we examine complications which arise from finite energy resolution. Furthermore we demonstrate that even in infinite systems a decline in $ρ_g(ω)$ with increasing disorder strength is not uniquely associated with localization.

Οι δύο εταιρίες επιλέχθηκαν ανάλογα με το επίπεδο ανάμιξης τους (υψηλό και χαμηλό) και οι αναρτήσεις τους επιλέχθηκαν ανάλογα με το επίπεδο ζήτησης της δράσης τους (διαδραστικές και στατικές).
description: This study focuses on companies and their presence on the most popular social media, Facebook. Recognizing the benefits that can be gained by a company from maintaining corporate presence on the network, this study makes an attempt to investigate the factors that can magnify the effect. As such factor, the study recognizes the consumer’s action on the company’s Facebook posts. At the same time, the study focuses on the consumer’s personality dimension of extraversion. It also studies the concepts of brand knowledge and brand loyalty. The research that has been conducted for this study, examines the concepts of consumer’s extraversion and Facebook intensity, the connection between brand knowledge and brand loyalty, and the level of action on the Facebook posts of two selected companies. The two companies were selected according to their level of involvement (high and low) and their posts were selected according to the level of calling for action (interactive and static).

description: Characterising the input-output photon-number distribution of an unknown optical quantum channel is an important task for many applications in quantum information processing. Ideally, this would require deterministic photon-number sources and photon-number-resolving detectors, but these technologies are still work-in-progress. In this work, we propose a general method to rigorously bound the input-output photon number distribution of an unknown optical channel using standard optical devices such as coherent light sources and non-photon-number-resolving detectors/homodyne detectors. To demonstrate the broad utility of our method, we consider the security analysis of practical quantum key distribution systems based on calibrated single-photon detectors and an experimental proposal to implement time-correlated single photon counting technology using homodyne detectors instead of single-photon detectors.

description: Using the new results on coherent elastic neutrino-nucleus scattering data in cesium-iodide provided by the COHERENT experiment, we determine a new measurement of the average neutron rms radius of $^{133}\text{Cs}$ and $^{127}\text{I}$. In combination with the atomic parity violation (APV) experimental result, we derive the most precise measurement of the neutron rms radii of $^{133}\text{Cs}$ and $^{127}\text{I}$, disentangling for the first time the contributions of the two nuclei. By exploiting these measurements we determine the corresponding neutron skin values for $^{133}\text{Cs}$ and $^{127}\text{I}$. These results suggest a preference for models which predict large neutron skin values, as corroborated by the only other electroweak measurements of the neutron skin of $^{208}\text{Pb}$ performed by PREX experiments. Moreover, for the first time, we obtain a data-driven APV+COHERENT measurement of the low-energy weak mixing angle with a percent uncertainty, independent of the value of the average neutron rms radius of $^{133}\text{Cs}$ and $^{127}\text{I}$, that is allowed to vary freely in the fit. The value of the low-energy weak mixing angle that we found is slightly larger than the standard model prediction.

description: In the application of autoregressive models the order of the model is often estimated using either a sequence of likelihood ratio tests, a likelihood based information criterion, or a residual based test. The properties of such procedures has been discussed extensively under the assumption that the characteristic roots of the autoregression are stationary. While non-stationary situations have also been considered the results in the literature depend on conditions to the characteristic roots. It is here shown that these methods for lag length determination can be used regardless of the assumption to the characteristic roots and also in the presence of deterministic terms. The proofs are based on methods developed by C. Z. Wei in his joint work with T. L. Lai.

description: The site frequency spectrum (SFS) is a popular summary statistic of genomic data. While the SFS of a constant-sized population undergoing neutral mutations has been extensively studied in population genetics, the rapidly growing amount of cancer genomic data has attracted interest in the spectrum of an exponentially growing population. Recent theoretical results have generally dealt with special or limiting cases, such as considering only cells with an infinite line of descent, assuming deterministic tumor growth, or taking large-time or large-population limits. In this work, we derive exact expressions for the expected SFS of a cell population that evolves according to a stochastic branching process, first for cells with an infinite line of descent and then for the total population, evaluated either at a fixed time (fixed-time spectrum) or at the stochastic time at which the population reaches a certain size (fixed-size spectrum). We find that while the rate of mutation scales the SFS of the total population linearly, the rates of cell birth and cell death change the shape of the spectrum at the small-frequency end, inducing a transition between a $1/j^2$ power-law spectrum and a $1/j$ spectrum as cell viability decreases. We show that this insight can in principle be used to estimate the ratio between the rate of cell death and cell birth, as well as the mutation rate, using the site frequency spectrum alone. Although the discussion is framed in terms of tumor dynamics, our results apply to any exponentially growing population of individuals undergoing neutral mutations.

description: We construct a two-dimensional microscopic model of interacting quantum dimers that displays an infinite number of periodic striped phases in its T=0 phase diagram. The phases form an incomplete devil's staircase and the period becomes arbitrarily large as the staircase is traversed. The Hamiltonian has purely short-range interactions, does not break any symmetries of the underlying square lattice, and is generic in that it does not involve the fine-tuning of a large number of parameters. Our model, a quantum mechanical analog of the Pokrovsky-Talapov model of fluctuating domain walls in two dimensional classical statistical mechanics, provides a mechanism by which striped phases with periods large compared to the lattice spacing can, in principle, form in frustrated quantum magnetic systems with only short-ranged interactions and no explicitly broken symmetries.

особенности преподавания
академическая мобильность

description: В статье освещены основные проблемы, возникающие при преподавании патофизиологии с сервисом перевода на английский и французский языки. Таковыми являются в первую очередь проблемы адаптации к новой образовательной, а также социально-культурной среде, различный уровень подготовки и языковых навыков и разное отношение к эксперименту над животными у студентов одной академической группы. Занятия, проводимые с сервисом перевода, являются менее информативными по сравнению с таковыми на родном языке. В связи с этим могут быть предложены следующие меры: повышение квалификации и языковых компетенций преподавателей для того, чтобы они могли преподавать на языке-посреднике, улучшение методической базы для преподавания, использование мультимедийных технологий и учебных видеофильмов.
Multiple ergodic averages in abelian groups and Khintchine type recurrence

description: Let $G$ be a countable abelian group. We study ergodic averages associated with configurations of the form $\{ag,bg,(a+b)g\}$ for some $a,b\in\mathbb{Z}$. Under some assumptions on $G$, we prove that the universal characteristic factor for these averages is a factor of a $2$-step nilpotent homogeneous space. As an application we derive a Khintchine type recurrence result. In particular, we prove that for every countable abelian group $G$, if $a,b\in\mathbb{Z}$ are such that $aG,bG,(b-a)G$ and $(a+b)G$ are of finite index in $G$, then for every $E\subset G$ and $\varepsilon>0$ the set $$\{g\in G : d(E\cap E-ag\cap E-bg\cap E-(a+b)g)\geq d(E)^4-\varepsilon\}$$ is syndetic. This generalizes previous results for $G=\mathbb{Z}$, $G=\mathbb{F}_p^ω$ and $G=\bigoplus_{p\in P}\mathbb{F}_p$ by Bergelson Host and Kra, Bergelson Tao and Ziegler and the author, respectively.

description: We employ neutron spherical polarimetry to determine the nature and population of the coexisting antiferromagnetic domains in multiferroic YMn2O5. By applying an electric field, we prove that reversing the electrical polarization results in the population inversion of two types of in-plane domains, related to each other by inversion. Our results are completely consistent with the exchange striction mechanism of ferroelectricity, and support a unified model where cycloidal ordering is induced by coupling to the main magnetic order parameter.

description: As a reflection of a terroir and a landscape, as an emblem of a region, a nation or a civilisation, wine also facilitates a connection between cultural dimensions that we are used to discriminating in our everyday representations (human/divine, human/animal, noble/common, beautiful/monstruous, natural/artificial). It is thus a vector of alterity, an invitation to go towards the other, to modify or alter one's vision of the world, to cross not only regional and national borders, but also the threshold between the profane and the sacred. It was therefore essential to combine the thoughts of wine professionals with those of researchers from many areas of the human sciences, from history to economics, linguistics, semiotics, communication sciences and literary criticism.
description: Reflet d'un terroir et d’un paysage, emblème d’une région, d’une nation ou d’une civilisation, le vin facilite aussi le rapprochement entre des dimensions culturelles que nous sommes habitués à distinguer dans nos représentations ordinaires (humain/divin, humain/animal, noble/vulgaire, beau/monstrueux, naturel/artificiel). Il est ainsi vecteur d’altérité, il invite à aller vers l’autre, à modifier ou altérer sa vision du monde, à franchir non seulement les frontières régionales et nationales, mais également le seuil séparant le profane du sacré. Il était donc indispensable d’associer les réflexions de professionnels spécialistes du vin à celles de chercheurs issus de nombreux secteurs des sciences humaines, de l’histoire à l’économie en passant par la linguistique, la sémiotique, les sciences de l’information et de la communication ou encore la critique littéraire.
Assessment of the Absorbed Dose Components of BNCT Method at the Dalat Research Reactor

Publisher: name: Zenodo
Year: 2024

description: At the Dalat Nuclear Research Reactor (DNRR) in Vietnam, some calculations and experiments of the Boron Neutron Capture Therapy (BNCT) method have been performed at horizontal channel No. 2 of the DNRR using a phantom. This research used the Monte Carlo N-Particle version 5 (MCNP5) code to simulate and calculate the distribution of absorbed dose components of the BNCT method. The collimator of horizontal neutron channel No. 2 of the DNRR was changed from cylindrical to conical to increase the flux of the neutron beam. Simultaneously, neutron crystal filters corresponding to 20 cm Si and 3 cm Bi are also employed to produce high-purity thermal neutron beams. The thermal neutron flux and absorbed dose components have been computed in a water phantom. The gamma dose from the reactor core of the DNRR can be omitted when calculating the total absorbed dose in the BNCT method.
Ground States of the SU(N) Heisenberg Model

description: The SU(N) Heisenberg model with various single-row representations is investigated by quantum Monte Carlo simulations. While the zero-temperature phase boundary agrees qualitatively with the theoretical predictions based on the 1/N expansion, some unexpected features are also observed. For N>=5 with the fundamental representation, for example, it is suggested that the ground states possess exact or approximate U(1) degeneracy. In addition, for the representation of Young tableau with more than one column, the ground state shows no valence-bond-solid order even at N greater than the threshold value.

description: We use a recently developed interpretable and unsupervised machine-learning method, the tensorial kernel support vector machine (TK-SVM), to investigate the low-temperature classical phase diagram of a generalized Heisenberg-Kitaev-$Γ$ ($J$-$K$-$Γ$) model on a honeycomb lattice. Aside from reproducing phases reported by previous quantum and classical studies, our machine finds a hitherto missed nested zigzag-stripy order and establishes the robustness of a recently identified modulated $S_3 \times Z_3$ phase, which emerges through the competition between the Kitaev and $Γ$ spin liquids, against Heisenberg interactions. The results imply that, in the restricted parameter space spanned by the three primary exchange interactions -- $J$, $K$, and $Γ$, the representative Kitaev material $α$-${\rm RuCl}_3$ lies close to the boundaries of several phases, including a simple ferromagnet, the unconventional $S_3 \times Z_3$ and nested zigzag-stripy magnets. A zigzag order is stabilized by a finite $Γ^{\prime}$ and/or $J_3$ term, whereas the four magnetic orders may compete in particular if $Γ^{\prime}$ is anti-ferromagnetic.

Purchasing power parity methods of making international comparisons
Creators: name: Hill, Robert J.
Publisher: name: University of British Columbia
Year: 2009

description: The objective of this dissertation is to improve our understanding of the various Purchasing Power Parity (PPP) methods that have been advocated in the literature on international comparisons. The first of three essays builds on the pioneering work of Van Yzeren(1987) to rationalize the literature, by constructing a taxonomy of PPP methods. In particular, the taxonomy reinterprets PPP methods in a graph theoretic context. This reinterpretation yields many useful insights. The second essay was motivated by the realization that virtually all PPP methods have the same underlying graph theoretic structure. This essay develops a new PPP method which allows the data to choose the underlying structure by using Kruskal’s “Minimum Spanning Tree” Graph Theory algorithm to chain PPPs across countries rather than imposing the structure ex ante. The Minimum Spanning Tree (MST) method may potentially dramatically simplify the procedure for constructing PPPs. The MST method also has important implications for time series comparisons. The essay concludes with an empirical comparison using 1990 OECD data between the MST method and the three most widely used PPP methods. The third essay focuses specifically on the Average Price class of PPP methods identified in the taxonomy. Average Price methods have the very desirable property of generating quantity indices that literally add up over different levels of aggregation when measured in value terms. However, it is widely claimed that Average Price methods overestimate the output shares of any outlier countries in a comparison. This is the so-called Gerschenkron effect. In spite of its significant implications, evidence for the Gerschenkron effect remains largely anecdotal. This essay explains the reasoning behind the Gerschenkron effect. As part of this explanation it is necessary to give a precise interpretation to the hitherto vague notion of an “outlier” country. Also frameworks are developed for empirically verifying and measuring the Gerschenkron effect, which are then applied to 1990 OECD data, with some surprising results.

Cascades of Failure and Extinction in Evolving Complex Systems

Publisher: name: arXiv
Year: 2006
Subjects: subject: Adaptation and Self-Organizing Systems (nlin.AO)

description: There is empirical evidence from a range of disciplines that as the connectivity of a network increases, we observe an increase in the average fitness of the system. But at the same time, there is an increase in the proportion of failure/extinction events which are extremely large. The probability of observing an extreme event remains very low, but it is markedly higher than in the system with lower degrees of connectivity. We give examples from complex systems such as outages in the US power grid, the robustness properties of cell biology networks, and trade links and the propagation of both currency crises and disease. We consider networks which are populated by agents which are heterogeneous in terms of their fitness for survival. The network evolves over time, and in each period agents take self-interested decisions to increase their fitness for survival to form alliances which increase the connectivity of the network. The network is subjected to external negative shocks both with respect to the size of the shock and the spatial impact of the shock. We examine the size/frequency distribution of extinctions and how this distribution evolves as the connectivity of the network grows. The results are robust with respect to the choice of statistical distribution of the shocks. We find that increasing the number of connections causes an increase in the average fitness of agents, yet at the same time makes the system as whole more vulnerable to catastrophic failure/extinction events on an near-global scale.
