description: Σκοπός της μελέτης είναι να αναδείξουμε την εξέχουσα προσωπικότητα και θεολογική κατάρτιση του βυζαντινού αυτοκράτορα Μανουήλ Β’ Παλαιολόγου(1391-1425μ.Χ) και της αντιισλαμικής του δράσης μέσα από τον διάλογο που είχε με ένα μωαμεθανό(Μουτερίζην) στο έργο του: «Διάλογος ὃν ἐποιήσατω μετά τινός Πέρσου, την ἀξίαν Μουτερίζη, ἐν Ἀγκύρα τῆς Γαλατίας». Αρχικά, παρουσιάζουμε την εμφάνιση της Ισλαμικής Θρησκείας και παράλληλα της Βυζαντινής αντιισλαμικής απολογητικής γραμματείας κατά τον 7ο αι. μ.Χ. Ακολούθως, εξετάζουμε την προσωπικότητα και το συγγραφικό έργο του Μανουήλ Β’ Παλαιολόγου όπως και την χειρόγραφή παράδοση του έργου του. Επιπρόσθετα, βλέπουμε τη σπουδαιότητα του έργου μέσα από τις διάφορες εκδόσεις του και από το ενδιαφέρον αρκετών ξένων και ελλήνων ερευνητών. Στη συνέχεια, παρουσιάζουμε τα περιστατικά διεξαγωγής και συγγραφής του διαλόγου με τον μωαμεθανό (Μουτερίζην). Ακόμη, μέσα από το έργο αυτό το οποίο αποτελείται από 26 διαλόγους καταφέραμε να ξεχωρίσουμε τα σημαντικότερα θέματα που απασχόλησαν τους συνομιλητές και να τα χωρίσουμε σε ενότητες. Συνεπώς, μέσα από τις ενότητες αυτές διατυπώνουμε τις θέσεις του Χριστιανισμού που έχει ως εκπρόσωπο του τον Μανουήλ Β’ Παλαιολόγο και τις θέσεις του Ισλάμ με εκπρόσωπο του τον Μωαμεθανό (Μουτερίζην). Εν κατακλείδι, διαπιστώνουμε την σπουδαιότητα του έργου «Διάλογος με Μωαμεθανό», το οποίο θα μπορούσε να αποτελέσει μια νέα βάση για ένα επικοδομοιτικό διαθρησκειακό διάλογο μεταξύ Χριστιανισμού και του Ισλάμ
description: The purpose of the study is to highlight the outstanding personality and theological training of the Byzantine emperor Manuel II Palaiologos (1391-1425μ.Χ) and his anti-Islamic action through the dialogue he had with a Muslim (Mouterisin) in the work «Dialogue with Perseus, Mouterisin, in the Anarch of Galatia». Initially, we present the appearance of the Islamic religion and the Byzantine anti-Islamic apologetic secretariat in the 7th century A.D. Next, we look at the personality and writing work of Manuel II Palaiologos as well as the handwritten tradition of his work. Additionally, we see the importance of the project through its various publications and the interest of several foreign and Greek researchers. Then we present the incidents of conducting and writing the dialogue with the Muslim (Mouterisin). Moreover, through this work, which consists of 26 dialogues, we managed to distinguish the most important issues that the interlocutors involved and to divide them into modules. Therefore, through these sections we formulate the positions of Christianity which has as its representative Manuel II Palaiologos and the positions of Islam with his representative Muslim (Muterisin). In conclusion, we note the importance of the project «Dialogue with Muslim», where it could be a new basis for a constructive interfaith dialogue between Christianity and Islam

description: We study a number of domain wall forming models where various types of defect junctions can exist. These illustrate some of the mechanisms that will determine the evolution of defect networks with junctions. Understanding these mechanisms is vital for a proper assessment of a number of cosmological scenarios: we will focus on the issue of whether or not cosmological frustrated domain wall networks can exist at all, but our results are also relevant for the dynamics of cosmic (super)strings, where junctions are expected to be ubiquitous. We also define and discuss the properties that would make up the ideal model in terms of hypothetical frustrated wall networks, and provide an explicit construction for such a model. We carry out a number of numerical simulations of the evolution of these networks, analyze and contrast their results, and discuss their implications for our no-frustration conjecture.

description: We study cluster and hypernuclei production in heavy-ion collisions at relativistic energies employing the Parton-Hadron-Quantum-Molecular-Dynamics (PHQMD) approach, a microscopic n-body transport model based on the QMD propagation of the baryonic degrees of freedom with density dependent 2-body potential interactions. All other ingredients of PHQMD, including the collision integral and the treatment of the quark-gluon plasma (QGP) phase, are adopted from the Parton-Hadron-String Dynamics (PHSD) approach. In PHQMD the cluster formation occurs dynamically, caused by the interactions. The clusters are recognized by the Minimum Spanning Tree (MST) algorithm. We present the PHQMD results for cluster and hypernuclei formation in comparison with the available experimental data at AGS, SPS, RHIC-BES and RHIC fixed target energies. We also provide predictions on cluster production for the upcoming FAIR and NICA experiments. PHQMD allows to study the time evolution of formed clusters and the origin of their production, which helps to understand how such weakly bound objects are formed and survive in the rather dense and hot environment created in heavy-ion collisions. It offers therefore an explanation of the 'ice in the fire' puzzle.

description: Coronaviruses can infect both human and animals and thus have medical and veterinary significance [1]. Bat might be the potential reservoir and source of virus in the current pandemic, SARS-CoV-2 (On 5th April 2020 [2,3], the United States Department of Agriculture’s (USDA) National Veterinary Services Laboratories screened one tiger positive for SARS-CoV-2 in the zoo at New York. Samples were obtained from this tiger and examined after many lions and tigers displayed signs of respiratory distress at the zoo [4]. According to the USDA report, a zoo employee was noticed to be responsible for the transmission of SARS-CoV-2 to the tiger. A study recently published has shown that SARS-CoV-2 uses human Angiotensin-converting enzyme 2 (ACE2) as cellular receptor during infection [5].

description: We present an ab initio study of pure and doped TiO2 in the rutile and anatase phases. The main purpose of this work is to determine the role played by different defects and different crystal structures in the appearance of magnetic order. The calculations were performed for varying impurity and vacancy concentrations in both TiO2 structures. For Co impurities the local magnetic moment remained almost independent of the concentration and distribution while for Cu this is not the case, there is magnetism for low concentrations that disappears for the higher ones. Impurity-impurity interactions in both structures favor linear ordering of them. Magnetism in un-doped samples appears for certain vacancy concentrations and structural strain.

description: In recent years, we have come to appreciate the astounding intricacy of the formation process of minerals from ions in aqueous solutions. In this context, a number of studies have revealed that nucleation in the calcium sulfate system is non-classical, involving the aggregation and reorganization of nanosized prenucleation particles. In a recent work we have shown that this particle-mediated nucleation pathway is actually imprinted in the resultant single micron-sized CaSO4 crystals. This property of CaSO4 minerals provides us with an unique opportunity to search for evidence of non-classical nucleation pathways in geological environments. In particular, we focused on the quintessential single crystals of anhydrite extracted from the Naica mine in Mexico. We elucidated the growth history from this mineral sample by mapping growth defects at different length scales. Based on these data we argue that the nano-scale misalignment of the structural sub-units observed in the initial calcium sulfate crystal seed propagate through different length-scales both in morphological, as well as strictly crystallographic aspects, eventually causing the formation of large mesostructured single crystals of anhydrite. Hence, the nanoparticle mediated nucleation mechanism introduces a 'seed of imperfection', which leads to a macroscopic single crystal, in which its fragments do not fit together at different length-scales in a self-similar manner. Consequently, anisotropic voids of various sizes are formed with very well-defined walls/edges. But, at the same time the material retains its essential single crystal nature. These findings shed new light on the longstanding concept of crystal structure.

Enhanced Non-local Power Corrections to the B->X_s+gamma Decay Rate

description: A new class of enhanced non-perturbative corrections to the inclusive B->X_s+gamma decay rate is identified, which contribute first at order Lambda/m_b in the heavy-quark expansion and cannot be described using a local operator product expansion. Instead, these effects are described in terms of hadronic matrix elements of non-local operators with component fields separated by light-like distances. They contribute to the high-energy part of the photon-energy spectrum but do not reduce to local operators when an integral over energy is taken to obtain the total inclusive decay rate. The dominant corrections depend on the flavor of the B-meson spectator quark and are described by tri-local four-quark operators. Their contribution is estimated using the vacuum insertion approximation. The corresponding uncertainty in the total decay rate is found to be at the few percent level. This new effect accounts for the leading contribution to the rate difference between B^- and B^0 mesons.

description: An in-depth understanding of the particular environment is crucial in reinforcement learning (RL). To address this challenge, the decision-making process of a mobile collaborative robotic assistant modeled by the Markov decision process (MDP) framework is studied in this paper. The optimal state-action combinations of the MDP are calculated with the non-linear Bellman optimality equations. This system of equations can be solved with relative ease by the computational power of Wolfram Mathematica, where the obtained optimal action-values point to the optimal policy. Unlike other RL algorithms, this methodology does not approximate the optimal behavior, it gives the exact, explicit solution, which provides a strong foundation for our study. With this, we offer new insights into understanding the action selection mechanisms in RL by presenting various small modifications on the very same schema that lead to different optimal policies.

description: We study the fluctuations in the distribution of zeros of zeta functions of a family of hyperelliptic curves defined over a fixed finite field, in the limit of large genus. According to the Riemann Hypothesis for curves, the zeros all lie on a circle. Their angles are uniformly distributed, so for a curve of genus g a fixed interval I will contain 2g|I| angles as the genus grows. We show that for the variance of number of angles in I is asymptotically a constant multiple of log(2g|I|) and prove a central limit theorem: The normalized fluctuations are Gaussian. These results continue to hold for shrinking intervals as long as the expected number of angles 2g|I| tends to infinity.

description: Nested sampling is an important tool for conducting Bayesian analysis in Astronomy and other fields, both for sampling complicated posterior distributions for parameter inference, and for computing marginal likelihoods for model comparison. One technical obstacle to using nested sampling in practice is the requirement (for most common implementations) that prior distributions be provided in the form of transformations from the unit hyper-cube to the target prior density. For many applications - particularly when using the posterior from one experiment as the prior for another - such a transformation is not readily available. In this letter we show that parametric bijectors trained on samples from a desired prior density provide a general-purpose method for constructing transformations from the uniform base density to a target prior, enabling the practical use of nested sampling under arbitrary priors. We demonstrate the use of trained bijectors in conjunction with nested sampling on a number of examples from cosmology.

description: A graph homomorphism between two graphs is a map from the vertex set of one graph to the vertex set of the other graph, that maps edges to edges. In this note we study the range of a uniformly chosen homomorphism from a graph G to the infinite line Z. It is shown that if the maximal degree of G is `sub-logarithmic', then the range of such a homomorphism is super-constant. Furthermore, some examples are provided, suggesting that perhaps for graphs with super-logarithmic degree, the range of a typical homomorphism is bounded. In particular, a sharp transition is shown for a specific family of graphs C_{n,k} (which is the tensor product of the n-cycle and a complete graph, with self-loops, of size k). That is, given any function psi(n) tending to infinity, the range of a typical homomorphism of C_{n,k} is super-constant for k = 2 log(n) - psi(n), and is 3 for k = 2 log(n) + psi(n).

FLAMINGOS-2 has a refractive all-spherical optical system providing 0.18-arcsecond pixels and a 6.2-arcminute circular field-of-view on a 2048x2048-pixel HAWAII-2 0.9-2.4 mm detector array. A slit/decker wheel mechanism allows the selection of up to 9 multi-object laser-machined plates or 3 long slits for spectroscopy over a 6x2-arcminute field of view, and selectable grisms provide resolutions from $\sim$ 1300 to $\sim $3000 over the entire spectrograph bandpass. FLAMINGOS-2 is also compatible with the Gemini Multi-Conjugate Adaptive Optics system, providing multi-object spectroscopic capabilities over a 3x1-arcminute field with high spatial resolution (0.09-arcsec/pixel). We review the designs of optical, mechanical, electronics, software, and On-Instrument WaveFront Sensor subsystems. We also present the current status of the project, currently in final testing in mid-2006.

description: Autism spectrum disorder is a developmental disorder characterized by significant social, communication, and behavioral challenges. Individuals diagnosed with autism, intellectual, and developmental disabilities (AUIDD) typically require long-term care and targeted treatment and teaching. Effective treatment of AUIDD relies on efficient and careful behavioral observations done by trained applied behavioral analysts (ABAs). However, this process overburdens ABAs by requiring the clinicians to collect and analyze data, identify the problem behaviors, conduct pattern analysis to categorize and predict categorical outcomes, hypothesize responsiveness to treatments, and detect the effects of treatment plans. Successful integration of digital technologies into clinical decision-making pipelines and the advancements in automated decision-making using Artificial Intelligence (AI) algorithms highlights the importance of augmenting teaching and treatments using novel algorithms and high-fidelity sensors. In this article, we present an AI-Augmented Learning and Applied Behavior Analytics (AI-ABA) platform to provide personalized treatment and learning plans to AUIDD individuals. By defining systematic experiments along with automated data collection and analysis, AI-ABA can promote self-regulative behavior using reinforcement-based augmented or virtual reality and other mobile platforms. Thus, AI-ABA could assist clinicians to focus on making precise data-driven decisions and increase the quality of individualized interventions for individuals with AUIDD.

Στην περίπτωση των βάσεων Groebner, η σύνδεση της Άλγεβρα με την Γεωμετρία έγινε εμφανής με την κατασκευή της καθολικής βάσης Groebner και της πολυεδρικής βεντάλιας Groebner.Στη συνέχεια ορίσαμε τα τορικά ιδεώδη και παρουσιάσαμε αλγορίθμους για τον υπολογισμό των βάσεων Groebner αυτών των ιδεωδών καθώς επίσης εισαγάγαμε τις έννοιες της βάσης Graver και της βάσης Hilbert.Τέλος μελετήσαμε τα πλεγματικά σύμπλοκα και τους τριγωνισμούς (κυρίως τους κανονικούς). Στη περίπτωση των τορικών ιδεωδών η σύνδεση της Άλγεβρας με την Γεωμετρία έγινε εμφανής από τους κώνους που δίνουν τις βάσεις Hilbert και από τους τριγωνισμούς με τις αντίστοιχες (δευτερεύουσες) βεντάλιες
description: The aim of the present thesis was to present the Algebra connection with Geometry through the Groebner bases and through the toric ideals. Initially we gave the definition of Groebner bases and the Buchberger algorithm to construct these bases. In the case of the Groebner bases, Algebra's connection to Geometry became apparent with the construction of the Groebner universal basis and the polyhedral Groebner fan. Then we defined the toric ideals and presented algorithms for calculating the Groebner bases of these ideals as well as introducing the concepts the Graver basis and the Hilbert basis. Finally we studied simplicial complexes and triangulations (mainly normal ones). In the case of toric ideals, Algebra's connection to Geometry became evident from cones that give the Hilbert bases and from the triangulations with the corresponding (secondary) fans

description: Let $G$ be a complex, linear algebraic group acting on an algebraic space $X$. The purpose of this paper is to prove a Riemann-Roch theorem (Theorem 5.3) which gives a description of the completion of the equivariant Grothendieck group $G_0(G,X)$ at any maximal ideal of the representation ring $R(G) \otimes \C$ in terms of equivariant cycles. The main new technique for proving this theorem is our non-abelian completion theorem (Theorem 4.3) for equivariant $K$-theory. Theorem 4.3 generalizes the classical localization theorems for diagonalizable group actions to arbitrary groups.

Πιο συγκεκριμένα, στο πρώτο κεφάλαιο επιχειρείται μια κριτική σύνοψη διαφορετικών θεωρητικών προσεγγίσεων του φανταστικού, με αφετηρία το μοντέλο που προτείνει ο Todorov στην Εισαγωγή στη φανταστική λογοτεχνία.

description: This work aims at a theoretical discussion of the concept of the fantastic, a comparative analysis of some key texts of the 19th and 20th century fantastic literature, as well as a first attempt to map a greek fantastic short story. More specifically, the first chapter attempts a critical summary of different theoretical approaches of the fantastic, starting from the model proposed by Todorov in The Fantastic: A Structural Approach to a Literary Genre. In particular, the element of the rift with a given perception of reality is investigated as a constitutive feature of the fantastic literature, while a special reference is made to the relationship between the fantastic and the short story. The second chapter examines in detail the different levels of the rift’s literary realization through a comparative reading of Edgar Allan Poe and Julio Cortázar, two writers with a deep affinity, who had a decisive influence on the evolution of the fantastic story. The last chapter of the work is an introductory scan of the fantastic in the field of modern greek literature with a brief examination of two illustrative short stories by K. P. Cavafy and K. G. Karyotakis, which broaden the dialogue between the two examined authors and design new regional streets of the fantastic literature

description: Certification of nonlocality of quantum mechanics is an important fundamental test that typically requires prolonged data collection and is only revealed in an in-depth analysis. These features are often particularly exposed in hybrid systems, such as interfaces between light and atomic ensembles. Certification of entanglement from images acquired with single-photon camera can mitigate this issue by exploiting multiplexed photon generation. Here we demonstrate this feature in a quantum memory (QM) operating in a real-time feedback mode. Through spatially-multimode spin-wave storage the QM enables operation of the real-time ghost imaging (GI) protocol. By properly preparing the spatial phase of light emitted by the atoms we enable observation of Bell-type nonlocality from a single image acquired in the far field as witnessed by the Bell parameter of $S=2.227\pm0.007>2$. Our results are an important step towards fast and efficient utilization of multimode quantum memories both in protocols and in fundamental tests.

description: We report magnetization and specific heat measurements on polycrystalline samples of BaCdVO(PO_4)_2 and show that this compound is a S=1/2 frustrated square lattice with ferromagnetic nearest-neighbor (J_1) and antiferromagnetic next-nearest-neighbor (J_2) interactions. The coupling constants J_1\simeq -3.6 K and J_2\simeq 3.2 K are determined from a fitting of the susceptibility data and confirmed by an analysis of the saturation field (H_s=4.2 T), the specific heat, and the magnetic entropy. BaCdVO(PO_4)_2 undergoes magnetic ordering at about 1 K, likely towards a columnar antiferromagnetic state. We find that BaCdVO(PO_4)_2 with the frustration ratio α=J_2/J_1\simeq -0.9 is closer to a critical (quantum spin liquid) region of the frustrated square lattice than any of the previously reported compounds. Positive curvature of the magnetization curve is observed in agreement with recent theoretical predictions for high-field properties of the frustrated square lattice close to the critical regime.

Implications of Local Friendliness violation for quantum causality

description: We provide a new formulation of the Local Friendliness no-go theorem of Bong et al [Nat. Phys. 16, 1199 (2020)] from fundamental causal principles, providing another perspective on how it puts strictly stronger bounds on quantum reality than Bell's theorem. In particular, quantum causal models have been proposed as a way to maintain a peaceful coexistence between quantum mechanics and relativistic causality, while respecting Leibniz's methodological principle. This works for Bell's theorem but does not work for the Local Friendliness no-go theorem, which considers an extended Wigner's Friend scenario. More radical conceptual renewal is required; we suggest that cleaving to Leibniz's principle requires extending relativity to events themselves.

Metal enrichment in galactic winds

description: Observations give evidences of the presence of metals in the intergalactic medium (IGM). The stars responsible for transforming hydrogen and helium into more complex atoms do not form outside the galaxies in the standard scenario of galaxy formation. Supernovae-driven winds and their associated feedback was proposed as a possible solution to explain such enrichment of the IGM. It turned out that a proper modelling of supernovae explosions within a turbulent interstellar medium (ISM) is a difficult task. Recent advances have been obtained using a multiphase approach to solve for the thermal state of the ISM, plus some additional recipes to account for the kinetic effect of supernovae on the galactic gas. We briefly describe here our implementation of supernovae feedback within the RAMSES code, and apply it to the formation and evolution of isolated galaxies of various masses and angular momenta. We have explored under what conditions a galactic wind can develop, if one considers only a quiescent mode of star formation. We have also characterized the distribution and evolution of metallicity in the gas outflow spreading in the IGM.

description: Geometric phases accompanying adiabatic quantum evolutions can be used to construct robust quantum control for quantum information processing due to their noise-resilient feature. A significant development along this line is to construct geometric gates using nonadiabatic quantum evolutions to reduce errors due to decoherence. However, it has been shown that nonadiabatic geometric gates are not necessarily more robust than dynamical ones, in contrast to an intuitive expectation. Here we experimentally investigate this issue for the case of nonadiabatic holonomic quantum computation~(NHQC) and show that conventional NHQC schemes cannot guarantee the expected robustness due to a cross coupling to the states outside the computational space. We implement a different set of constraints for gate construction in order to suppress such cross coupling to achieve an enhanced robustness. Using a superconducting quantum circuit, we demonstrate high-fidelity holonomic gates whose infidelity against quasi-static transverse errors can be suppressed up to the fourth order, instead of the second order in conventional NHQC and dynamical gates. In addition, we explicitly measure the accumulated dynamical phase due to the above mentioned cross coupling and verify that it is indeed much reduced in our NHQC scheme. We further demonstrate a protocol for constructing two-qubit NHQC gates also with an enhanced robustness.

description: Σκοπός της παρούσας μεταπτυχιακής εργασίας ήταν η πραγματοποίηση της σχολιασμένης μετάφρασης του άρθρου “Rethinking GDP” της Diane Coyle από την αγγλική στην ελληνική γλώσσα. Αρχικά, παρουσιάστηκε η μετάφραση του άρθρου από την αγγλική στην ελληνική γλώσσα, σε δυο στοιχισμένες στήλες. Έπειτα, ακολούθησε το γλωσσάρι των όρων που είχαν εξαχθεί από το άρθρο και η τεκμηρίωση των όρων. Στη συνέχεια, έγινε εκτενής αναφορά στην ορολογική έρευνα και τεκμηρίωση των όρων, με ανάλυση της ερευνητικής διαδικασίας που ακολουθήθηκε. Ακόμη, αναλύθηκαν οι χαρακτηριστικές μεταφραστικές δυσκολίες που προέκυψαν κατά τη διάρκεια της μετάφρασης, τόσο μορφοσυντακτικές όσο και λεξιλογικές - ορολογικές
description: The aim of the present Master Thesis was the annotated translation of the article “Rethinking GDP” by Diane Coyle from the English to the Greek language. Firstly, the translation of the article from the English to the Greek language was presented in two aligned columns. Then followed the glossary of the terms which had been extracted from the article and the term validation. Furthermore, there was an extensive reference to the terminological research and term validation, with an analysis of the research procedure which had been followed. In addition, the characteristic translation difficulties which arose during the translation procedure, both morphosyntactic and lexical - terminological were analysed

description: A fiducial cross section for W$γ$ production in proton-proton collisions is measured at a center-of-mass energy of 13 TeV in 137 fb$^{-1}$ of data collected using the CMS detector at the LHC. The W $\to$ e$ν$ and $μν$ decay modes are used in a maximum-likelihood fit to the lepton-photon invariant mass distribution to extract the combined cross section. The measured cross section is compared with theoretical expectations at next-to-leading order in quantum chromodynamics. In addition, 95% confidence level intervals are reported for anomalous triple-gauge couplings within the framework of effective field theory.
