description: The rich magnetic anisotropy of compressively strained (Ga,Mn)As has attracted great interest recently. Here we discuss a sensitive method to visualize and quantify the individual components of the magnetic anisotropy using transport. A set of high resolution transport measurements is compiled into color coded resistance polar plots, which constitute a fingerprint of the symmetry components of the anisotropy. As a demonstration of the sensitivity of the method, we show that these typically reveal the presence of both the [-110] and the [010] uniaxial magnetic anisotropy component in (Ga,Mn)As layers, even when most other techniques reveal only one of these components.

description: We present a model-based real-time method to monitor a counterflow heat exchanger's thermal performance for all operating conditions. A first principle reference model that describes the reference counterflow process in an accurate manner is derived first. Real gas behavior is taken into account. Without simplifications, the respective equations must be solved in an iterative, computationally expensive manner, which prohibits their use for real-time monitoring purposes. Therefore, we propose one-step-solvable model equations, resulting in an approximate but quick model, which is able to track an important thermal property reliably. The monitoring, i.e., the online estimation of the thermal properties, is achieved via a nonlinear Kalman-Filter. Due to the low-order dynamic model formulation, the overall monitoring scheme is accompanied by an acceptable computational burden. Moreover, it is easy to deploy and to adapt in industrial practice. Monitoring results, where the reference model replaces a real process with supercritical carbon dioxide, are given and discussed herein.

description: Η παράκτια λεκάνη του Θερμαϊκού είναι η επέκταση προς τα βορειοδυτικά της υπεράκτιας λεκάνης του Θερμαϊκού, που βρίσκεται γεωγραφικά στη βόρειο Ελλάδα. Αποτελεί μία ιζηματογενή λεκάνη, όπου ιζήματα που χρονολογούνται από το Παλαιογενές μέχρι το Τεταρτογενές επικαλύπτουν παλαιότερους οφιολιθικούς σχηματισμούς και σχηματισμούς βαθιάς θάλασσας της γεωτεκτονικής ζώνης του Αξιού, που χρονολογούνται στο Μεσοζωικό. Στην εν λόγω περιοχή έχουν πραγματοποιηθεί πολυάριθμες γεωλογικές και γεωφυσικές έρευνες κατά τον προηγούμενο αιώνα, σε συνδυασμό με την όρυξη γεωτρήσεων, που έδωσαν σημαντικά αποτελέσματα σχετικά με την εξέλιξη της λεκάνης και τις πιθανές δομές αποθήκευσης υδρογοναθράκων που περιέχει. Για την πλήρη επεξεργασία των δεδομένων δυναμικού πεδίου, δηλαδή των βαρυτικών και μαγνητικών δεδομένων, αρχικά και των σεισμικών δεδομένων στη συνέχεια, ακολουθείται ένας αριθμός διαδικασιών και μεθόδων, με απώτερο σκοπό την κατασκευή μοντέλων βάθους που αναπαριστούν το πραγματικό γεωλογικό καθεστώς της περιοχής. Στην παρούσα Διατριβή, δεδομένα δυναμικών πεδίων, μαζί με σεισμικά δεδομένα και δεδομένα γεωφυσικών διαγραφιών, χρησιμοποιήθηκαν για την κατασκευή μοντέλων βάθους δύο διαστάσεων για την παράκτια λεκάνη του Θερμαϊκού, καθώς επίσης και για την επιβεβαίωση ύπαρξης γεωλογικών δομών που πιθανώς περιέχουν κοιτάσματα υδρογοναθράκων ή, διαφορετικά, μπορούν να χρησιμοποιηθούν ως υπόγειοι αποθηκευτικοί χώροι για ποσότητες φυσικού αερίου
description: The onshore Thermaikos basin is the northwestern extension of offshore Thermaikos basin, located at northern Greece. It consists a sedimentary basin, where sediments dating from Paleogene to Quaternary are overlaying the older ophiolite and deep-sea Mesozoic formations of Axios geotectonic zone. At this area, a number of geological and geophysical surveys has been realized during the previous century, along with well drilling, that gave important results concerning the basin’s evolution and the possible hydrocarbon traps it contains. For the complete processing of potential field, i.e. gravity and magnetic, data initially and seismic data afterwards, numerous procedures and methods are followed, for the purpose of constructing depth models that simulate the actual underground geologic regime. Potential field data, along with seismic and logging data, were used at this Thesis in order to construct 2-D depth models of the basin and to confirm the existence of geologic structures that could contain hydrocarbon reserves or could, otherwise, be utilized as storage for natural gas quantities

description: This paper is devoted to the computation of compact binaries composed of one black hole and one neutron star. The objects are assumed to be on exact circular orbits. Standard 3+1 decomposition of Einstein equations is performed and the conformal flatness approximation is used. The obtained system of elliptic equations is solved by means of multi-domain spectral methods. Results are compared with previous work both in the high mass ratio limit and for one neutron star with very low compactness parameter. The accuracy of the present code is shown to be greater than with previous codes. Moreover, for the first time, some sequences containing one neutron star of realistic compactness are presented and discussed.

description: Sodium-ion batteries (SIBs) have emerged as promising alternatives to lithium-ion batteries for grid energy storage and automotive applications. However, their widespread adoption necessitates improved cycling stability and energy density, largely dependent on electrode materials and electrolytes. This study investigates the compatibility and performance of the diglyme-based localized high concentration electrolyte (LHCE/G2) for SIB applications, proposing it as the electrolyte of choice for materials screening in half-cell configuration. Three layered oxide cathode materials were tested in LHCE/G2 against sodium metal counter electrodes, demonstrating significantly enhanced cycling stability compared to carbonate electrolytes. The electrochemical stability of LHCE/G2 on sodium metal was confirmed through long-term plating/stripping profiles. The findings suggest that glyme-based LHCEs offer a promising approach to evaluating high-voltage oxide cathodes, minimizing electrolyte-related degradation, and enhancing the reliability and performance of SIBs.

description: Deep Learning as a field has been successfully used to solve a plethora of complex problems, the likes of which we could not have imagined a few decades back. But as many benefits as it brings, there are still ways in which it can be used to bring harm to our society. Deep fakes have been proven to be one such problem, and now more than ever, when any individual can create a fake image or video simply using an application on the smartphone, there need to be some countermeasures, with which we can detect if the image or video is a fake or real and dispose of the problem threatening the trustworthiness of online information. Although the Deep fakes created by neural networks, may seem to be as real as a real image or video, it still leaves behind spatial and temporal traces or signatures after moderation, these signatures while being invisible to a human eye can be detected with the help of a neural network trained to specialize in Deep fake detection. In this paper, we analyze several such states of the art neural networks (MesoNet, ResNet-50, VGG-19, and Xception Net) and compare them against each other, to find an optimal solution for various scenarios like real-time deep fake detection to be deployed in online social media platforms where the classification should be made as fast as possible or for a small news agency where the classification need not be in real-time but requires utmost accuracy.

Inhomogeneous D-Wave Superconductivity and Antiferromagnetism in a Two-Dimensional Extended Hubbard Model with Nearest-Neighbor Attractive Interaction

Year: 2006
Subjects: subject: Superconductivity (cond-mat.supr-con)

description: To understand the interplay of d-wave superconductivity and antiferromagnetism, we consider a two-dimensional extended Hubbard model with nearest neighbor attractive interaction. The Hamiltonian is solved in the mean-field approximation on a finite lattice. In the impurity-free case, the minimum energy solutions show phase separation as predicted previously based on free energy argument. The phase separation tendency implies that the system can be easily rendered inhomogeneous by a small external perturbation. Explicit solutions of a model including weak impurity potentials are indeed inhomogeneous in the spin-density-wave and d-wave pairing order parameters. Relevance of the results to the inhomogeneous cuprate superconductors is discussed.

description: In order to treat all-to-all connected quadratic binary optimization problems (QUBO) with hardware quantum annealers, an embedding of the original problem is required due to the sparsity of the hardware's topology. Embedding fully-connected graphs - typically found in industrial applications - incurs a quadratic space overhead and thus a significant overhead in the time to solution. Here we investigate this embedding penalty of established planar embedding schemes such as minor embedding on a square lattice, minor embedding on a Chimera graph, and the Lechner-Hauke-Zoller scheme using simulated quantum annealing on classical hardware. Large-scale quantum Monte Carlo simulation suggest a polynomial time-to-solution overhead. Our results demonstrate that standard analog quantum annealing hardware is at a disadvantage in comparison to classical digital annealers, as well as gate-model quantum annealers and could also serve as benchmark for improvements of the standard quantum annealing protocol.

Second and foreign language programmes in France
Creators: name: Maironi, Elisabeth
Publisher: name: University of British Columbia
Year: 2008

description: Current second language programmes in elementary school in France that aim at providing instruction in regional, foreign European or immigrant languages are critically examined, not separately, as it has been done up to now, but all together and in a broader context. The historical development leading to the dominance of French, but also to the demand for instruction in other languages, is presented to explain the existence and objectives of the various programmes. The concept of language needs, often used but seldom defined, is discussed briefly, and the arguments for early language instruction are reviewed. The chronology, successes and failures of the various foreign language programmes or experiments, in particular the most recent one, are investigated using official documents and results of evaluations. The analysis reveals shortcomings in organization and teachers' training and the necessity of improving teaching methods to meet the challenges of instruction in a variety of languages at a high level of quality. For the latter purpose, methods that have been successful in other contexts are reviewed, in particular the immersion method and the self-learning method used in Canada, and the methods of the so-called European Schools. The conclusions are as follows. In order to respond to the demands of the public and the pressure of the international economic and political stiuation, French schools should be able to produce at least bilingual citizens. To this end, it is highly desirable to start foreign language instruction as early as possible. It should start at the beginning of elementary school for all children in France, and every child should continue to learn the language it has had in elementary school in secondary school. Instruction in elementary school should focus on comprehension, but after secondary school the students should be able to speak at least one foreign language. To make the instruction more efficient, a more flexible method that incorporates ideas from immersion and self-learning is proposed. Moreover, to improve organizational aspects, it is proposed that parents get the opportunity to control the programme more strictly. Eventually, these programmes should evolve after the model of the European School, which has proven very successful.

description: The dissertation analyzes in detail the cervical spinal column. Firstly describes the anatomy and physiology of the neck and then expands on the diseases and injuries of the neck, the second part explains each cervical disease separately, the symptoms and the methods of rehabilitation and treatment for each and tries to find the factors that cause the cervical diseases to suggest solutions. The third part compares scientific research and articles from authoritative medical sources that mention the causes and symptoms of cervical pain that tends to become one of the most massive and painful diseases of modern society. By comparing these studies, we draw useful conclusions that can be used by anyone to prevent and treat cervical diseases. Alternative methods of physiotherapy and rehabilitation are also being proposed along with conventional treatments such as medication, use of collars and perhaps surgical treatment in the most painful cases. So every patient can choose with their physician the method that will help most and will reduce the pain or completely eliminate its causes

description: The aim of the present thesis was the study of the Greek insurance system from the point of view of retirement and more specifically the analysis of the current situation during the dismissal or resignation of the employee due to retirement. We looked at all the types of social security schemes that exist, as well as the conditions for full or partial retirement receipt. We then presented in detail the age limits set as a reason for the termination of an employment contract, the issue of age discrimination created, but also the existence or not of objective reasons which may on a case-by-case basis justify such discrimination. We also referred in detail to the termination of the employment contract issue as a result of the completion of the retirement conditions and we were particularly concerned with the issue regarding the given compensation at both national and European level. Another issue we raised was the one concerning the compensation in the case of the re-employment of an already retired person and we presented the views of both Court- decisions and the theory. We also dealt with the voluntary exit programmes but also the issue of the protection of personal data with regard to the employer and the possibility whether or not to have access to the personal data of his employees in order to terminate their employment contract when they fulfill the conditions of retirement

Δευτερευόντως, μελετήθηκε η σχέση της ηλικίας, του ύψους και του βάρους με το αναφερόμενο εμβαδό. Με βάση τα αποτελέσματα της παρούσας μελέτης, το εμβαδό του λιπώδους σώματος της επιγονατίδας δεν συσχετίζεται με τον δείκτη μάζας σώματος, ούτε στους άνδρες αλλά ούτε και στις γυναίκες. Και στα δύο φύλα το βάρος φαίνεται να έχει σημαντική θετική συσχέτιση με το εμβαδόν του λιπώδους σώματος. Επίσης, με την πάροδο της ηλικίας στις γυναίκες το εμβαδό του λιπώδους σώματος ελαττώνεται σημαντικά. Όσον αφορά στο ύψος, και στα δύο φύλα το μεγαλύτερο ύψος συνεπάγεται και μεγαλύτερο εμβαδό του λιπώδους σώματος της επιγονατίδας
description: In the present study, the key question was whether there was any correlation between the maximal area of the infrapatellar fat pad (Hoffa’s Fat Pad) measured in the sagittal plane, with the body mass index, using magnetic resonance imaging. Secondly, the relationship of age, height and weight with the reported area was studied. Based on the results, we concluded that the area was not correlated with the body mass index in either men or women. However, there was a positive correlation between weight and the area of the infrapatellar fat pad, for both sexes. It has also been shown that the size of the infrapatellar fat pad decreases significantly, as women grow older. In terms of height, for both sexes it was found that the higher height implies a larger area of the infrapatellar fat pad

description: The paper addresses the bistability caused by spontaneous symmetry breaking bifurcation in a one-dimensional periodically corrugated nonlinear waveguide pumped by coherent light at normal incidence. The formation and the stability of the switching waves connecting the states of different symmetries are studied numerically. It is shown that the switching waves can form stable resting and moving bound states (dissipative solitons). The protocols of the creation of discussed nonlinear localized waves are suggested and verified by numerical simulations.

description: Partendo dalla testimonianza di Tacito – grazie alla quale è possibile ricostruire per grandi linee lo ‘stile economico’ dell’Alto impero – si nota come negli anni dal 16 al 33 d.C. si affermino specificità caratteristiche della società romana, quali una politica finanziaria vòlta a sanare gli scompensi strutturali dell’economia agraria, l’intensificarsi del commercio con l’Oriente (ulteriore implemento al dilagare del luxus), una res publica imperniata sul princeps e sulla nobilitas senatoria, l’incremento dell’indice demografico servile. Lo studio si propone come un contributo alla discussione sulla presunta ‘razionalità dominatrice’, che avrebbe caratterizzato i ceti dirigenti romani e sul ruolo svolto dal principe in questa complessa dinamica, in cui il suo intervento fu ideologicamente sollecitato da quei gruppi di potere che più amavano mostrarsi legati al mos maiorum. On the basis of Tacitus’ witness – thanks to which the ‘economic style’ of the High Empire can be reconstructed in broad terms – could be pointed out that, in the years 16 to 22 A.D., some basic features of the Roman society get established, including a financial policy designed to overcome structural financial problems in the agra­ri­an economy, the intensification of the trade with the Orient (further cause of spreading of luxus), a res publica rotated around princeps and senatorial nobilitas, the increase in the average of slavish population. This paper aims to contribute to the discussion on the ‘dominant rationality’ that might have characterized the ruling roman classes, and on the role played by the Prince in this complex dynamic, whose intervention was requested by those powers that liked to show themselves true to the mos maiorum.

description: The existence of the radius of marginal stability means that accretion flows around black holes invariably undergo a transition from a MHD turbulent disk-like flow to an inward plunging flow. We argue that the plunging inflow can greatly enhance the trapping of large scale magnetic field on the black hole, and therefore may increase the importance of the Blandford-Znajek (BZ) effect relative to previous estimates that ignore the plunge region. We support this hypothesis by constructing and analyzing a toy-model of the dragging and trapping of a large scale field by a black hole disk, revealing a strong dependence of this effect on the effective magnetic Prandtl number of the MHD turbulent disk. Furthermore, we show that the enhancement of the BZ effect depends on the geometric thickness of the accretion disk. This may be, at least in part, the physical underpinnings of the empirical relation between the inferred geometric thickness of a black hole disk and the presence of a radio jet.

Ως εκ τούτου καλείται να εκτονώσει διαχρονικούς προβληματισμούς και διχοστασίες του εννοιολογικού του οπλοστασίου [Ζητήματα Δόλου, Αιτιότητας και Συμμετοχής]. Στις γραμμές που ακολουθούν δεν ήταν δυνατό να δοθούν τελειωτικές απαντήσεις. Η εκτενής όμως παρουσίαση των συχνά αντίρροπων συνιστωσών του ζητήματος καθώς και των εκατέρωθεν αδιεξόδων κατέδειξε τουλάχιστο πως τέτοιες ακόμη δεν έχουν δοθεί.
description: In the present study, an attempt is made to critically approach perhaps the most complex chapter of participation, that of indirect perpetration. Through the ongoing struggle among the typical- objective [integration of indirect perpetration into the current penal system] and substantial-objective theory [theory of domination over the action], an attempt is being made to establish a more complete dogmatic foundation and at the same time to prove that even this, meets limits and difficulties. Above all, it is demonstrated that the institution of indirect perpetration is inextricably linked to almost the entire General Part of Criminal Law. Therefore, it is called upon to relieve timeless concerns and divisions of its conceptual arsenal [Issues of culpability and deceit, Causality and Participation]. In the following lines it was not possible to give final answers. However, the analytical presentation of the often contradictory components of the issue as well as the impasses on both sides showed at least that such answers have not yet been given generally.

description: The AGS equations are solved for $n{}^3\mathrm{H}$ and $p{}^3\mathrm{He}$ scattering including the Coulomb interaction. Comparison with previous work confirms the accuracy of the calculation and helps clarify a number of issues related to the $n{}^3\mathrm{H}$ total cross section at the peak of the resonance region, as well as an $A_y$ deficiency in $p{}^3\mathrm{He}$. Calculations are fully converged in terms of $NN$ partial waves and involve no uncontrolled approximations.

description: Chest radiography is a relatively cheap, widely available medical procedure that conveys key information for making diagnostic decisions. Chest X-rays are almost always used in the diagnosis of respiratory diseases such as pneumonia or the recent COVID-19. In this paper, we propose a self-supervised deep neural network that is pretrained on an unlabeled chest X-ray dataset. The learned representations are transferred to downstream task - the classification of respiratory diseases. The results obtained on four public datasets show that our approach yields competitive results without requiring large amounts of labeled training data.

Quasi-potentials in the Nonequilibrium Stationary States or a method to get explicit solutions of Hamilton-Jacobi equations

Year: 2021

description: We assume that a system at a mesoscopic scale is described by a field $ϕ(x,t)$ that evolves by a Langevin equation with a white noise whose intensity is controlled by a parameter $1/\sqrtΩ$. The system stationary state distribution in the small noise limit ($Ω\rightarrow\infty$) is of the form $P_{st}[ϕ]\simeq\exp(-ΩV_0[ϕ])$ where $V_0[ϕ]$ is called the {\it quasipotential}. $V_0$ is the unknown of a Hamilton-Jacobi equation. Therefore, $V_0$ can be written as an action computed along a path that is the solution from Hamilton's equation that typically cannot be solved explicitly. This paper presents a theoretical scheme that builds a suitable canonical transformation that permits us to do such integration by deforming the original path into a straight line. We show that this can be done when a set of conditions on the canonical transformation and the model's dynamics are fulfilled. In such cases, we can get the quasipotential algebraically. We apply the scheme to several one-dimensional nonequilibrium models as the diffusive and reaction-diffusion systems.

description: We have measured the angular dependence of ferromagnetic resonance (FMR) spectra for Fibonacci-distorted, Kagome artificial spin ice (ASI). The number of strong modes in the FMR spectra depend on the orientation of the applied DC magnetic field. In addition, discontinuities observed in the FMR field-frequency dispersion curves also depend on DC field orientation, and signal a multi-step DC magnetization reversal, which is caused by the reduced energy degeneracy of Fibonacci-distorted vertices. The results suggest the orientation of applied magnetic field and severity of Fibonacci distortion constitute control variables for FMR modes and multi-step reversal in future magnonic devices and magnetic switching systems.

description: Η παρούσα εργασία αφορά τον νοηματικό σχεδιασμό μιας έκθεσης με θέμα τον Κρητικό ζωγράφο Δομήνικο Θεοτοκόπουλο. Πιο συγκεκριμένα αναφέρεται στην οπτική Ελλήνων Λογοτεχνών του 20ου αιώνα για τον διάσημο ζωγράφο, που αναφέρθηκαν σε αυτόν μέσα από τα κείμενα τους. Η πρόταση αυτή αφορά μια περιοδική έκθεση για την αίθουσα περιοδικών εκθέσεων «Κυριάκος Κρόκος» του Μουσείου Βυζαντινού Πολιτισμού Θεσσαλονίκης. Ο χώρος του μουσείου θεωρήθηκε κατάλληλος εφόσον ο ζωγράφος είχε έντονα βυζαντινά κατάλοιπα που συνδύασε με Αναγεννησιακά στοιχεία στην ζωγραφική του. Ο σκοπός είναι να δοθεί μια καινοτόμα οπτική για τον ζωγράφο, που απασχόλησε τόσο πολύ μετά τον θάνατο του και να μπορέσει το κοινό να τον δει μέσα από τα μάτια ανθρώπων των γραμμάτων που δεν τον γνώρισαν ποτέ αλλά τον θαύμασαν έντονα.
description: This thesis presents a suggestion about an exhibition concerning Crecian painter Domenicos Theotokopoulos. In particular, this exhibition gives the prospect of Greek literature of 20th Century, which has many mentions about this famous painter. This conceptual proposal is about a temporary exhibition at the museum of byzantine culture of Thessaloniki and especially the temporary exhibition wing “Kyriakos Krokos”. This place is a great option because of Domenico’s art technique which combines parts of byzantine and renaissance art techniques. The certain goal of this exhibition is to give an innovative aspect of Domenicos, who has an effect to art even years after his death, and give to the visitors the opportunity to get to know him from the aspect of Greek litterateurs, that appreciate him strongly even though they didn’t know him personally.

description: In recent years, regional economic resilience has become a promising research field in academia. As a metaphor, regional economic resilience has witnessed a theoretical progress from an equilibrium perspective to the adaptive and evolutionary perspective. Recently, some literature has begun to discuss the spatial spillover effects of regional economic resilience. Following this vein, we compare the spatial patterns of China’s regional economic resilience with respect to a geographic network as well as an economic network. Taking the financial crisis as an example, we implement spatial Markov chains to derive the spatial transition matrices of regional economic resilience. Moreover, we use network-based methods to identify the role of network node degree on regional economic resilience. In particular, we figure out that regions with higher node degree in intercity investment networks tend to be less resilient to the global financial crisis, while they also have more significant negative spillover effects on neighbouring regions as well as investment partners. Our findings not only add to the network perspective of regional economic resilience but also offer constructive suggestions for city governors and planners.

description: Questo contributo si propone di ricostruire la vicenda editoriale de «Il Riscatto», storico periodico della sinistra messinese pubblicato a partire dalla fine dell’Ottocento. L’articolo concentra la propria attenzione sull’ultima stagione editoriale del periodico, tra gli anni ’50 e ’70 dello scorso secolo, quando «Il Riscatto» divenne un giornale d’informazione alternativa sotto la guida delle locali federazioni del Partito comunista e del Partito socialista. Le cronache de «Il Riscatto» e lo studio della sua linea editoriale offrono un punto di vista interessante per la ricostruzione delle vicende politiche, socio-economiche e culturali del territorio messinese e siciliano in quegli anni. The aim of this article is to reconstruct the history of «Il Riscatto», a remarkable newspaper published in Messina by the Left from the late 19th century. The article focuses on the last period, between the 50’s and 70’s of last century, when «Il Riscatto», became an alternative newspaper controlled by the local Communist and Socialist federations. The chronicles taken from «Il Riscatto» and the research about the editorial line, can give us an interesting point of view to recreate the local political, social, economic and cultural events in Messina and in Sicily during those years.

High-pT pi0 Production with Respect to the Reaction Plane Using the PHENIX Detector at RHIC

description: The origin of the azimuthal anisotropy in particle yields at high pT (pT > 5 GeV/c) in RHIC collisions remains an intriguing puzzle. Traditional flow and parton energy loss models have failed to completely explain the large v2 observed at high pT. Measurement of this parameter at high pT will help to gain an understanding of the interplay between flow, recombination and energy loss, and the role they play in the transition from soft to hard physics. Neutral mesons measured in the PHENIX experiment provide an ideal observable for such studies. We present recent measurements of \piz yields with respect to the reaction plane, and discuss the impact current models have on our understanding of these mechanisms.

description: The length-based approach is a heuristic for solving randomly generated equations in groups which possess a reasonably behaved length function. We describe several improvements of the previously suggested length-based algorithms, that make them applicable to Thompson's group with significant success rates. In particular, this shows that the Shpilrain-Ushakov public key cryptosystem based on Thompson's group is insecure, and suggests that no practical public key cryptosystem based on this group can be secure.
