description: Stars can either be formed in or captured by the accretion disks in Active Galactic Nuclei (AGN). These AGN stars are irradiated and subject to extreme levels of accretion, which can turn even low-mass stars into very massive ones ($M > 100 {\rm M}_\odot$) whose evolution may result in the formation of massive compact objects ($M > 10 {\rm M}_\odot$). Here we explore the spins of these AGN stars and the remnants they leave behind. We find that AGN stars rapidly spin up via accretion, eventually reaching near-critical rotation rates. They further maintain near-critical rotation even as they shed their envelopes, become compact, and undergo late stages of burning. This makes them good candidates to produce high-spin massive black holes, such as the ones seen by LIGO-Virgo in GW190521g, as well as long Gamma Ray Bursts (GRBs) and the associated chemical pollution of the AGN disk.

description: We investigate the quantization of a free particle coupled linearly to a harmonic oscillator. This system, whose classical counterpart has clearly separated regular and chaotic regions, provides an ideal framework for studying the quantization of mixed systems. We identify key signatures of the classically chaotic and regular portions in the quantum system by constructing Husimi distributions and investigating avoided level crossings of eigenvalues as functions of the strength and range of the interaction between the system's two components. We show, in particular, that the Husimi structure becomes mixed and delocalized as the classical dynamics becomes more chaotic.

Multilinguism was our thematic priority because nowadays is a political, economical, cultural and socialtoolofconsolidation, unity and solidarity between nations and sepa-rately. Moreover multilinguism , in a legal framework according to the directivities of EU, open the cultural borders, facilitating communication and helping people to inte-grate trough individual and collective projects. In addition, lifelong learning is an in-dispensable part of expanded civilized European cluster and opens wide the doors of professional achievement and generally communication ability. The projects of EU make easy learning and teaching languages and allow through the exchange of physi-cal presence to provide adequate knowledge and communication skills. Master’s thesis is divided in three sections: a) documentation source’s validity of pro-totype, b) translation of articles [two] for the multilinguism and c) measure.
Electric Quantum Oscillation in Weyl Semimetals

description: Electronic transport in Weyl semimetals is quite extraordinary due to the topological property of the chiral anomaly generating the charge pumping between two distant Weyl nodes with opposite chiralities under parallel electric and magnetic fields. Here, we develop a full nonequilibrium quantum transport theory of the chiral anomaly, based on the fact that the chiral charge pumping is essentially nothing but the Bloch oscillation. Specifically, by using the Keldysh nonequilibrium Green function method, it is shown that there is a rich structure in the chiral anomaly transport, including the negative magnetoresistance, the non-Ohmic behavior, the Esaki-Tsu peak, and finally the resonant oscillation of the DC electric current as a function of electric field, called the electric quantum oscillation. We argue that, going beyond the usual behavior of linear response, the non-Ohmic behavior observed in BiSb alloys can be regarded as a precursor to the occurrence of electric quantum oscillation, which is both topologically and energetically protected in Weyl semimetals.

description: We present new WFC3/UVIS observations of UGC 4483, the closest example of a metal-poor blue compact dwarf galaxy, with a metallicity of $Z \simeq 1/15\ Z_{\odot}$ and located at a distance of $D \simeq 3.4$ Mpc. The extremely high quality of our new data allows us to clearly resolve the multiple stellar evolutionary phases populating the color-magnitude diagram (CMD), to reach more than 4 mag deeper than the tip of the red giant branch, and to detect for the first time core He-burning stars with masses $\lesssim 2$ M$_{\odot}$, populating the red clump and possibly the horizontal branch (HB) of the galaxy. By applying the synthetic CMD method to our observations, we determine an average star formation rate over the whole Hubble time of at least $(7.01\pm0.44) \times 10^{-4}$ $\mathrm{M_{\odot}/yr}$, corresponding to a total astrated stellar mass of $(9.60\pm0.61)\times 10^6$ $\mathrm{M_{\odot}}$, 87% of which went into stars at epochs earlier than 1 Gyr ago. With our star formation history recovery method we find the best fit with a distance modulus of DM = $27.45\pm0.10$, slightly lower than previous estimates. Finally, we find strong evidence of an old ($\gtrsim 10$ Gyr) stellar population in UGC 4483 thanks to the detection of an HB phase and the identification of six candidate RR Lyrae variable stars.

Initialization Matters: Regularizing Manifold-informed Initialization for Neural Recommendation Systems

description: Proper initialization is crucial to the optimization and the generalization of neural networks. However, most existing neural recommendation systems initialize the user and item embeddings randomly. In this work, we propose a new initialization scheme for user and item embeddings called Laplacian Eigenmaps with Popularity-based Regularization for Isolated Data (LEPORID). LEPORID endows the embeddings with information regarding multi-scale neighborhood structures on the data manifold and performs adaptive regularization to compensate for high embedding variance on the tail of the data distribution. Exploiting matrix sparsity, LEPORID embeddings can be computed efficiently. We evaluate LEPORID in a wide range of neural recommendation models. In contrast to the recent surprising finding that the simple K-nearest-neighbor (KNN) method often outperforms neural recommendation systems, we show that existing neural systems initialized with LEPORID often perform on par or better than KNN. To maximize the effects of the initialization, we propose the Dual-Loss Residual Recommendation (DLR2) network, which, when initialized with LEPORID, substantially outperforms both traditional and state-of-the-art neural recommender systems.
The spin-Peierls transition beyond the adiabatic approximation

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We develop a theory of the spin-Peierls transition taking into account the three dimensional character of the phonon field. Our approach does not rely on the adiabatic or mean field treatment for the phonons. It is instead based in the exact integration of the phonon field, the exact long wavelength solution of the one chain spin problem, and then a mean field approximation for the interchain interaction. We show that the spin gap and the critical temperature are strongly reduced due to the finite frequency effects of the phonon coupling transverse to the magnetic chains. We claim that our results should be applicable to the inorganic spin-Peierls compound CuGeO$_3$. We show that the long standing discussion on absence of a soft mode in this compound can be naturally resolved within our theory.

Εξετάστηκαν οι έννοιες της διγλωσσίας, της δίγλωσσης εκπαίδευσης, της εναλλαγής κωδίκων –κυρίως ως κοινωνιογλωσσικό φαινόμενο- και της εναλλαγής κωδίκων στην παιδική ηλικία και πως αυτή συμβάλλει στην διατήρηση των «ασθενών» γλωσσών. Το διδακτικό μοντέλο προσπαθεί να εκκινήσει την Εναλλαγή Κωδίκων και, μέσα από τις δραστηριότητες που προτείνει, στοχεύει στην αποδοχή του γλωσσικού και πολιτισμικού κεφαλαίου των μαθητών και μαθητριών. Οι γλώσσες των μαθητών και μαθητριών συμπεριλαμβάνονται ως ισάξιες, ως πηγή γνώσης και ως μέρη των ταυτοτήτων των παιδιών. Τέλος περιγράφονται οι τρεις περιπτώσεις που εφαρμόστηκε το προτεινόμενο μοντέλο και τα αποτελέσματά τους.
description: The aim of this thesis is the proposal of a teaching model that uses Code-switching on the first school age. We examined the terms of bilingualism, bilingual education, code-switching- mostly as a sociolinguistic phenomenon- and code-switching in childhood and how it contributes to the maintenance of the “weak” language. The teaching proposal tries to engage Code-switching and through its activities aims to the inclusion and acceptance of students’ language and cultural background. The languages are treated as equal, as sources of knowledge and as part of the students’ identity. Lastly, we describe how the teaching proposal was utilized at three case studies and their results.

description: We present an analysis of the variations seen in the dispersion measures (DMs) of 20 millisecond pulsars observed as part of the Parkes Pulsar Timing Array project. We carry out a statistically rigorous structure function analysis for each pulsar and show that the variations seen for most pulsars are consistent with those expected for an interstellar medium characterised by a Kolmogorov turbulence spectrum. The structure functions for PSRs J1045-4509 and J1909-3744 provide the first clear evidence for a large inner scale, possibly due to ion-neutral damping. We also show the effect of the solar wind on the DMs and show that the simple models presently implemented into pulsar timing packages cannot reliably correct for this effect. For the first time we clearly show how DM variations affect pulsar timing residuals and how they can be corrected in order to obtain the highest possible timing precision. Even with our presently limited data span, the residuals (and all parameters derived from the timing) for six of our pulsars have been significantly improved by correcting for the DM variations.

A postcolonial conception of the high school multicultural literature curriculum
Creators: name: Greenlaw, James C.
Publisher: name: University of British Columbia
Year: 2009

description: Currently, in many high schools throughout Canada and the United States, English teachers have been developing literature curricula to meet the needs of their culturally diverse students. However, because in most cases these educators have not had at their disposal the interpretative techniques of such postcolonial literary theorists as Edward Said and Gayatri Spivak, they have been relying, instead, for their reading strategies upon traditional literary theories. Unfortunately, when teachers employ New Critical, archetypal, feminist, or reader-response methods of literary analysis in their reading of multicultural literature, they are often unaware of the Eurocentric biases contained within these perspectives. This lack of understanding of their theoretical frame of reference can then lead teachers to encourage their students to accept uncritically problematic representations of various cultural groups as they encounter these representations in their literary texts. Postcolonial literary theory, on the other hand, encourages students to problematize Eurocentric representations of imperialism’s Others. The advantage to students who use postcolonial reading strategies in order to become aware of the different ways in which people at the margins and centres of empire view each other is that they can thus attain higher levels of multicultural literacy by performing more sophisticated and complex interpretations of their texts than they might have done using traditional interpretative approaches. At the same time, the students’ use of postcolonial reading strategies can help them to become more effective intercultural communicators as they cross cultural borders by carrying out collaborative responses to literary texts with students whose heritage differs from their own. This project, therefore, involves a critique of existing conceptions of the high school multicultural literature curriculum by comparing their key features with those of the postcolonial conception. The principal focus of the investigation is upon how the postcolonial approach can help students to understand, more effectively than can traditional conceptions, the necessarily dynamic and heterogeneous textual representations of dominant and subaltern cultures to be found in both Eurocentric and postcolonial literary texts.

description: We study string breaking in the three dimensional SU(2) Higgs model, using values of the gauge coupling for which the confinement-like and Higgs-like regions of the phase diagram are separated just by a smooth crossover. We show that even in the presence of string breaking, the confining part of the interquark potential is well described by the Effective String Theory and that also the fine details of the effective string, like the higher order terms of the Nambu-Goto action or the boundary correction, can be precisely extracted from the fits and agree with the effective string predictions. We comment on the implications of these results for QCD simulations with dynamical quarks.

description: The present postgraduate thesis, deals with the modeling and the management of the ground-water aquifer system of Katerini (915), Greece. The area under study is analyzed extensively. Morphological, geological, hydrogeological data are presented, as well the water budget and the land use. A simulation of groundwater flow under steady state, using a finite-difference ground-water model, commonly called MODFLOW, is elaborated based on available data and information provided by previous studies and research on area under study. The model is adequately calibrated in order to be used for groundwater simulation and management in the area under study. Next, management scenarios are presented for the reduction of the seawater inflow and the achievement of smaller groundwater drawdown. Finally, a reallocation of groundwater extractions is proposed, in order to meet the water demand for the study area while avoiding the risk of seawater intrusion

description: VPIC is a general purpose Particle-in-Cell simulation code for modeling plasma phenomena such as magnetic reconnection, fusion, solar weather, and laser-plasma interaction in three dimensions using large numbers of particles. VPIC's capacity in both fidelity and scale makes it particularly well-suited for plasma research on pre-exascale and exascale platforms. In this paper we demonstrate the unique challenges involved in preparing the VPIC code for operation at exascale, outlining important optimizations to make VPIC efficient on accelerators. Specifically, we show the work undertaken in adapting VPIC to exploit the portability-enabling framework Kokkos and highlight the enhancements to VPIC's modeling capabilities to achieve performance at exascale. We assess the achieved performance-portability trade-off through a suite of studies on nine different varieties of modern pre-exascale hardware. Our performance-portability study includes weak-scaling runs on three of the top ten TOP500 supercomputers, as well as a comparison of low-level system performance of hardware from four different vendors.

description: We carry out a comprehensive theoretical and experimental study of charge injection in Poly(3-hexylthiophene) (P3HT) to determine the most likely scenario for metal-insulator transition in this system. We calculate the optical absorption frequencies corresponding to a polaron and a bipolaron lattice in P3HT. We also analyze the electronic excitations for three possible scenarios under which a first-- or a second--order metal--insulator transition can occur in doped P3HT. These theoretical scenarios are compared with data from infrared absorption spectroscopy on P3HT thin film field-effect transistors (FET). Our measurements and theoretical predictions suggest that charge-induced localized states in P3HT FETs are bipolarons and that the highest doping level achieved in our experiments approaches that required for a first-order metal--insulator transition.

description: The aim of our thesis was to highlight the most important points of the bio-works of St. Maximus Greek on the subject of monasticism. In the first chapter we presented his Christian origin and his studies in the West and his dedication to God. Then we referred to his life in the Athonian state and also we make a reference to his valuable work within the Russian Church regarding the translation and correction of the church’s books. Furthermore, we examined the spiritual environment of Russia and the reasons that led to the condemnation of the saint. In the second chapter we dealt with the teachings and letters of the saint concerning monasticism. We have thoroughly analyzed basic issues and minor issues as well that have been developed in his work. Finally, we arrived to some conclusions about the personality of the holy monk

description: We develop the Cauchy theory of the spatially homogeneous inelastic Boltzmann equation for hard spheres, for a general form of collision rate which includes in particular variable restitution coefficients depending on the kinetic energy and the relative velocity as well as the sticky particles model. We prove (local in time) non-concentration estimates in Orlicz spaces, from which we deduce weak stability and existence theorem. Strong stability together with uniqueness and instantaneous appearance of exponential moments are proved under additional smoothness assumption on the initial datum, for a restricted class of collision rates. Concerning the long-time behaviour, we give conditions for the cooling process to occur or not in finite time.

description: Urbanization is a major land use type that has considerable impacts on stream ecosystems and their species richness and abundance. Streams in urban settings are affected by multiple stressors; flow modifications, changes in nutrient concentrations, and loss of riparian vegetation. Aquatic insect richness and abundance directly reflect these alterations and can be used to assess urban impacts on streams. Odonates are important predators in aquatic environments, and they serve as links between aquatic and terrestrial environments. Unfortunately, the effects of urbanization on odonate richness and abundance in tropical islands is poorly understood. The objective of this study is to determine the effects of urbanization on stream habitat quality and associated odonate assemblages in Puerto Rico. A total of 16 streams along a rural-urban gradient in the San Juan Metropolitan area (SJMA) were characterized using the Stream Visual Assessment Protocol (SVAP) for Puerto Rico. A 100m reach of each stream was surveyed twice for 30min to assess adult odonate richness and abundance during the rainy (2018) and dry (2019) seasons. Adults were identified visually on the fly and their abundance was recorded. Odonate richness ranged from 2 to 9, and abundance from 5 to 382. The SVAP positively correlated to abundance, but not to richness. Even though adult abundance and richness were higher in the dry season, these were not found to be statistically significant. Overall, our study indicates odonate assemblages are not diverse in the SJMA and are affected by changes in stream habitat condition because of urbanization.

description: A novel class of integrable $σ$-models interpolating between exact coset conformal field theories in the IR and hyperbolic spaces in the UV is constructed. We demonstrate the relation to the asymptotic limit of $λ$-deformed models for cosets of non-compact groups. An integrable model interpolating between two spacetimes with cosmological and black hole interpretations and exact conformal field theory descriptions is also provided. In the process of our work, a new zoom-in limit, distinct from the well known non-Abelian T-duality limit, is found.

description: Potential bioactive molecules must reach the target tissue safely and serum albumin, which is a well-known major component in human blood, is an efficient transporter. Therefore, the interactions of possible bioactive species with serum albumin must be determined. In the current study, an N-heterocyclic carbene precursor and its silver complex were synthesized, characterized, and analyzed for interactions with bovine serum albumin. Stern-Volmer constant was recorded as 4.50 × 105 for Ag-NHC with a 1.255 binding number at 298 K. Also, the molecules have spontaneously interacted with bovine serum albumin with a negative ΔG value (−32.93 kJ mol−1) for the complex at 298 K. Additionally, the effects of Ca2+, Mg2+, and Zn2+ on binding properties were evaluated by fluorescence spectroscopy. The binding constant of the complex was recorded as 6.76 × 103 in the presence of Zn2+ and 5.93 × 105 without the metals. The molecules were optimized by DFT-based calculations and the details of the bindings were investigated by molecular docking methods. Ag-NHC has interacted with the IIA subdomain region of bovine serum albumin with −8.46 kcal/mol.
An alternative paradigm for conservation education: innovations in the public presentation of killer whales at the Vancouver Aquarium

Publisher: name: University of British Columbia

description: Conservation is the number one goal of modern zoos and aquaria. Public education is the primary means through which zoos and aquaria attempt to fulfill their conservation goal. Yet, nearly two decades after its initial adoption, conservation education fails to be effectively translated into practice. This thesis argues that the entertainment paradigm in which zoos and aquaria have traditionally operated is at odds with their contemporary goal of conservation education, thus continued adherence to this entertainment paradigm prevents zoos and aquaria from effectively implementing conservation education. The thesis proposes an alternative paradigm in which conservation education may be successfully achieved. Killer whales present an ideal case example through which to explore the impact of the entertainment paradigm on conservation education. Since they were first displayed in 1964, these animals have been consistently presented in a show format. Today, the Vancouver Aquarium is the only institution in the world to present killer whales outside the context of a show. This thesis uses examples from the Vancouver Aquarium to describe how innovations within an alternative paradigm resulted in the Aquarium's unique approach to killer whale interpretation and animal care, and how these innovations have been successfully implemented into the practice of conservation education in the Vancouver Aquarium's public galleries.
Synaptic plasticity of Inhibitory synapse promote synchrony in inhibitory network in presence of heterogeneity and noise

description: Recently spike timing dependent plasticity was observed in inhibitory synapse in the layer II of entorhinal cortex. The rule provides an interesting zero in the region of $Δt=t_{post}-t_{pre}=0$ and in addition the dynamic range of the rule lie in gamma frequency band. We propose a robust mechanism based on this observed synaptic plasticity rule for inhibitory synapses for two mutually coupled interneurons to phase lock in synchrony in the presence of intrisic heterogeneity in firing. We study the stability of the phase locked solution by defining a map for spike times dependent on the phase response curve for the coupled neurons. Finally we present results on robustness of synchronization in the presence of noise.

description: Σκοπός της διατριβής ήταν η παροχή χρήσιμων πληροφοριών από κλιματολογική και συνοπτική πλευρά για το φαινόμενο της ομίχλης, η παράθεση και εφαρμογή μεθοδολογιών πρόγνωσης σχηματισμού και διάλυσής της, και η ποσοτικοποίηση της κατανομής των ακυρώσεων και καθυστερήσεων των πτήσεων, ώστε να συνεισφέρουν στην καλύτερη κατανόηση του φαινομένου και στη δυνητικότητα βελτίωσης της πρόγνωσης, με όσο το δυνατόν την εύρυθμη λειτουργία του αεροδρομίου. Από την κλιματολογική μελέτη για την περίοδο 1971-2014 πρόεκυψε ότι περίπου 19 μέρες το χρόνο επικρατεί ομίχλη, κυρίως το τρίμηνο Νοεμβρίου-Ιανουαρίου (63%) και τα επεισόδια διαρκούν κατά μέσο όρο 4 ώρες. Οι ομίχλες σχηματίζονται πρωτίστως μεταξύ 6 και 8 τοπική ώρα (30,2%) και διαλύονται μεταξύ 8 και 12 τοπική ώρα με συχνότητα διάλυσης 59%. Η συνοπτική μελέτη για τη χρονική περίοδο 2001-2010 έδειξε ότι μεγαλύτερη συχνότητα εμφάνισης στο αεροδρόμιο Μακεδονία έχουν οι ομίχλες ακτινοβολίας (34%) και οι ομίχλες ελάττωσης της βάσης του νέφους (28%). Οι ομίχλες ακτινοβολίας διαρκούν περισότερο, ενώ οι ομίχλες εξάτμισης διαλύονται πολύ γρήγορα. Η νοτιοδυτική κυκλοφορία ευνοεί το σχηματισμό των επεισοδίων ομίχλης με συχνότητα 39%. Η μεθοδολογία Saunders εφαρμόστηκε και είχε καλά αποτελέσματα
description: The aim of the present thesis is to provide useful information from a climatological and synoptic point of view of the fog phenomenon, to present and apply methodologies for fog formation and dissipation forecast, and to to quantify the distribution of delay-flights and canceled-flights of the airport, so as to contribute to a better understanding of the phenomenon and to a possible improvement of the forecast. The climatological study for the period 1971-2014, showed that the average annual number of fog episodes is about 19, with the greater frequency (63%) to be encountered from November till January. Episodes last 4 hours on average. Fog is formed mainly (30,2%) between 6 and 8 local time and dissipate mainly between 8 and 12 local time with a dissipation frequency of 59%. From the synoptic study for the period 2001-2010, has emerged that types of fog at the Macedonia airport are most frequently radiation fogs and cloud base lowering fogs by 34% and 28% respectively. Radiation fogs last longer, while evaporation fogs dissipate very quickly. The southwest flow is the most favorable one with a frequency of 39%. Saunders techique was applied and had good results

The Momentum Four-Vector in the $eψ$N Formalism and the Angular Momentum Imparted to Test Particles by Gravitational Waves

description: Since gravitational waves are solutions of Einstein's field equations with a zero stress-energy tensor, the reality of these waves was questioned. To demonstrate it, the momentum imparted to test particles by such waves was evaluated. A closed form expression for this quantity was provided by Qadir and Sharif, using an extension of the pseudo-Newtonian formalism. That formalism carried with it the zero component of the momentum vector, which could not be interpreted as the energy imparted to the test particle. Sharif proposed that it may represent the angular momentum imparted to test particles by gravitational waves. In this paper it is shown that this interpretation is not valid. An alternative explanation has been provided.

description: Automated semantic segmentation and object detection are of great importance in geospatial data analysis. However, supervised machine learning systems such as convolutional neural networks require large corpora of annotated training data. Especially in the geospatial domain, such datasets are quite scarce. Within this paper, we aim to alleviate this issue by introducing a new annotated 3D dataset that is unique in three ways: i) The dataset consists of both an Unmanned Aerial Vehicle (UAV) laser scanning point cloud and a 3D textured mesh. ii) The point cloud features a mean point density of about 800 pts/sqm and the oblique imagery used for 3D mesh texturing realizes a ground sampling distance of about 2-3 cm. This enables the identification of fine-grained structures and represents the state of the art in UAV-based mapping. iii) Both data modalities will be published for a total of three epochs allowing applications such as change detection. The dataset depicts the village of Hessigheim (Germany), henceforth referred to as H3D. It is designed to promote research in the field of 3D data analysis on one hand and to evaluate and rank existing and emerging approaches for semantic segmentation of both data modalities on the other hand. Ultimately, we hope that H3D will become a widely used benchmark dataset in company with the well-established ISPRS Vaihingen 3D Semantic Labeling Challenge benchmark (V3D). The dataset can be downloaded from https://ifpwww.ifp.uni-stuttgart.de/benchmark/hessigheim/default.aspx.
