description: Machine learning (ML) methods are being used in almost every conceivable area of electronic structure theory and molecular simulation. In particular, ML has become firmly established in the construction of high-dimensional interatomic potentials. Not a day goes by without another proof of principle being published on how ML methods can represent and predict quantum mechanical properties - be they observable, such as molecular polarizabilities, or not, such as atomic charges. As ML is becoming pervasive in electronic structure theory and molecular simulation, we provide an overview of how atomistic computational modeling is being transformed by the incorporation of ML approaches. From the perspective of the practitioner in the field, we assess how common workflows to predict structure, dynamics, and spectroscopy are affected by ML. Finally, we discuss how a tighter and lasting integration of ML methods with computational chemistry and materials science can be achieved and what it will mean for research practice, software development, and postgraduate training.

description: Σκοπός της παρούσας μελέτης ήταν να διερευνήσει τη σχέση της ανίας ως γνώρισμα προσωπικότητας σε φοιτητικό πληθυσμό με τους παράγοντες πρόβλεψης και τις στρατηγικές αντιμετώπισης της. Δείγμα αποτέλεσαν 400 προπτυχιακοί και μεταπτυχιακοί φοιτητές από διάφορα Πανεπιστήμια και Τμήματα της Ελλάδας. Η συμμετοχή στην έρευνα ήταν εθελοντική και έγινε με τη βοήθεια ηλεκτρονικών ερωτηματολογίων και με ερωτηματολόγια που χορηγήθηκαν σε έντυπη μορφή κατά τη διάρκεια των μαθημάτων στο Αριστοτέλειο Πανεπιστήμιο Θεσσαλονίκης. Τα εργαλεία που χρησιμοποιήθηκαν ήταν τρία ερωτηματολόγια αυτο-αναφοράς: (α) ένα ερωτηματολόγιο μέτρησης της ανίας ως γνώρισμα προσωπικότητας, (β) ένα ερωτηματολόγιο των παραγόντων που ενεργοποιούν την ανία κατά την παρακολούθηση μαθημάτων στο Πανεπιστήμιο και (γ) ένα ερωτηματολόγιο για τις στρατηγικές αντιμετώπισης της ανίας. Τα αποτελέσματα της έρευνας έδειξαν ότι οι αιτίες της ανίας όπως η αίσθηση ότι το άτομο χάνει το χρόνο του, ότι το μάθημα είναι δύσκολό ή πολύ εύκολο και ότι το μάθημα είναι βαρετό ή μονότονος ο καθηγητής, συσχετίζονται υψηλότερα με την ανία ως γνώρισμα προσωπικότητας. Η ανία ως γνώρισμα προσωπικότητας φάνηκε να συσχετίζεται υψηλότερα με τη χρήση στρατηγικών συμπεριφορικής αποφυγής σύμφωνα με τις αναφορές των φοιτητών/τριών. Ενώ συσχέτιση υπήρξε και μεταξύ των αιτιών που αναφέρουν οι φοιτητές/τριες και του είδους των στρατηγικών που χρησιμοποιούν για την αντιμετώπιση της ανίας τους. Τέλος, βρέθηκαν στατιστικώς σημαντικές διαφορές τόσο σε σχέση με το φύλο των συμμετεχόντων/ουσών όσο και με το έτος/επίπεδο των σπουδών τους
description: The aim of this study was to investigate the emotion of boredom as a personality trait, its antecedents and coping strategies in university students. The sample was 400 undergraduate and postgraduate students from several universities and departments in Greece. Three online self-reported questionnaires and questionnaires that were given in printed form during the courses at the Aristotle University of Thessaloniki were used for measuring: (a) boredom as a trait, (b) the antecedents that trigger boredom while attending University courses and (c) the boredom coping strategies. The results of the research highlighted that antecedents of boredom such as the feeling of losing time, the courses’ level of difficulty and/or interest and the teacher not being monotonous, are significantly correlated with boredom as a trait. Further, boredom as a trait correlated significantly with the use of behavioral avoidance strategies. Different coping strategies significantly correlated with specific self-reported antecedents of boredom. The gender and the year/level of studies were found to significantly differentiate students’ reports for both boredom and the antecedents and coping strategies of boredom
Black Hole Microstates and Attractor Without Supersymmetry

description: Due to the attractor mechanism, the entropy of an extremal black hole does not vary continuously as we vary the asymptotic values of various moduli fields. Using this fact we argue that the entropy of an extremal black hole in string theory, calculated for a range of values of the asymptotic moduli for which the microscopic theory is strongly coupled, should match the statistical entropy of the same system calculated for a range of values of the asymptotic moduli for which the microscopic theory is weakly coupled. This argument does not rely on supersymmetry and applies equally well to nonsupersymmetric extremal black holes. We discuss several examples which support this argument and also several caveats which could invalidate this argument.

Deficiency of Broad Line AGNs in Compact Groups of Galaxies

description: Based on a new survey of AGN activity in Compact Groups of Galaxies, we report a remarkable deficiency of Broad Line AGNs as compared to Narrow Line AGNs. The cause of such deficiency could be related to the average low luminosity of AGNs in CGs: $10^{39}$ erg s$^{-1}$. This result may imply lower accretion rates in CG AGNs, making Broad Line Regions (BLR) undetectable, or may indicate a genuine absence of BLRs. Both phenomena are consistent with gas stripping through tidal interaction and dry mergers.

description: Combining with the small-large black hole phase transition, the thermodynamic geometry has been well applied to study the microstructure for the charged AdS black hole. In this paper, we extend the geometric approach to the rotating Kerr-AdS black hole and aim to develop a general approach for the Kerr-AdS black hole. Treating the entropy and pressure as the fluctuation coordinates, we construct the Ruppeiner geometry for the Kerr-AdS black hole by making the use of the Christodoulou-Ruffini-like squared-mass formula, which is quite different from the charged case. Employing the empirical observation of the corresponding scalar curvature, we find that, for the near-extremal Kerr-AdS black hole, the repulsive interaction dominates among its microstructure. While for far-from-extremal Kerr-AdS black hole, the attractive interaction dominates. The critical phenomenon is also observed for the scalar curvature. These results uncover the characteristic microstructure of the Kerr-AdS black hole. Such general thermodynamic geometry approach is worth generalizing to other rotating AdS black holes, and more interesting microstructure is expected to be discovered.

The concept of a complete set of independent characteristic integrals underlying Darboux integrability is discussed. A close connection is found between integrals and characteristic Lie-Rinehart algebras of the system. It is proved that a system of equations is Darboux integrable if and only if its characteristic algebras in both directions are finite-dimensional.

description: We present new parametrisations of energy spectra of secondary particles, $π$-mesons, gamma-rays, electrons and neutrinos, produced in inelastic proton-proton collisions. The simple analytical approximations based on imulations of proton-proton interactions using the public available SIBYLL code, provide very good accuracy for energy distributions of secondary products in the energy range above 100 GeV. Generally, the recommended analytical formulae deviate from the simulated distributions within a few percent over a large range of $x=E_i/E_p$ - the fraction of energy of the incident proton transferred to the secondaries. Finally, we describe an approximate procedure of continuation of calculations towards low energies, down to the threshold of $π$-meson production.

description: The present dissertation, titled “Myths and stereotypes of male prostitution in contemporary greek prose”, aims to detect the ways in which male sex work is represented in contemporary literary production, and especially in the short stories “Sta tessera” (“On four”) written by Kostas Peroulis and included in the short story collection Aftomata (Automatics), and “Prasinos” (“Green”) written by Iakovos Anyfantakis and included in the short story collection Omorfi erotes (Beautiful loves). Consequently, this dissertation attempts to examine whether this representation contributes to the renewal of the discussion about prostitution and sexuality. In our attempt, we made use of Kostas Yannakopoulos’ anthropological study about homosexual culture of the two largest greek urban centers (Athens and Thessaloniki) during the decades ’50-’70, as well as the conflicting viewpoints on prostitution. In addition, into consideration were also taken the queer theory, historic details about greek gay movement and contemporary –international and greek– studies about male sex work

description: We present a detailed analysis of the dynamical response of ultra-cold bosonic atoms in a one-dimensional optical lattice subjected to a periodic modulation of the lattice depth. Following the experimental realization by Stoferle et al [Phys. Rev. Lett. 92, 130403 (2004)] we study the excitation spectrum of the system as revealed by the response of the total energy as a function of the modulation frequency Omega. By using the Time Evolving Block Decimation algorithm, we are able to simulate one-dimensional systems comparable in size to those in the experiment, with harmonic trapping and across many lattice depths ranging from the Mott-insulator to the superfluid regime. Our results produce many of the features seen in the experiment, namely a broad response in the superfluid regime, and narrow discrete resonances in the Mott-insulator regime. We identify several signatures of the superfluid-Mott insulator transition that are manifested in the spectrum as it evolves from one limit to the other.

description: Precise measurements of the spin structure functions of the proton $g_1^p(x,Q^2)$ and deuteron $g_1^d(x,Q^2)$ are presented over the kinematic range $0.0041 \leq x \leq 0.9$ and $0.18 $ GeV$^2$ $\leq Q^2 \leq 20$ GeV$^2$. The data were collected at the HERMES experiment at DESY, in deep-inelastic scattering of 27.6 GeV longitudinally polarized positrons off longitudinally polarized hydrogen and deuterium gas targets internal to the HERA storage ring. The neutron spin structure function $g_1^n$ is extracted by combining proton and deuteron data. The integrals of $g_1^{p,d}$ at $Q^2=5$ GeV$^2$ are evaluated over the measured $x$ range. Neglecting any possible contribution to the $g_1^d$ integral from the region $x \leq 0.021$, a value of $0.330 \pm 0.011\mathrm{(theo.)}\pm0.025\mathrm{(exp.)}\pm 0.028$(evol.) is obtained for the flavor-singlet axial charge $a_0$ in a leading-twist NNLO analysis.

description: It is shown that a 25(20)% difference between the decay constants $f_{D_s}(f_{B_s})$ and $f_D(f_B)$ occurs due to large differences in the pole masses of the $s$ and $d(u)$ quarks. The values $η_D =f_{D_s}/f_D\approx 1.23(15)$, recently observed in the CLEO experiment, and $η_B=f_{B_s}/f_B\approx 1.20$, obtained in unquenched lattice QCD, can be reached only if the running mass $m_s$ at low scale is $m_s(\sim 0.5 $ GeV)$= 170 - 200$ MeV. Our results follow from the analytical expression for the pseudoscalar decay constant $f_{\rm P}$ based on the path-integral representation of the meson Green's function.

description: We present the theoretical framework to efficiently solve the Jeans equations for multi-component axisymmetric stellar systems, focusing on the scaling of all quantities entering them. The models may include an arbitrary number of stellar distributions, a dark matter halo, and a central supermassive black hole; each stellar distribution is implicitly described by a two- or three-integral distribution function, and the stellar components can have different structural (density profile, flattening, mass, scale-length), dynamical (rotation, velocity dispersion anisotropy), and population (age, metallicity, initial mass function, mass-to-light ratio) properties. In order to determine the ordered rotational velocity and the azimuthal velocity dispersion fields of each component, we introduce a decomposition that can be used when the commonly adopted Satoh decomposition cannot be applied. The scheme developed is particularly suitable for a numerical implementation; we describe its realisation within our code JASMINE2, optimised to maximally exploit the scalings allowed by the Poisson and the Jeans equations, also in the post-processing procedures. As applications, we illustrate the building of three multi-component galaxy models with two distinct stellar populations, a central black hole, and a dark matter halo; we also study the solution of the Jeans equations for an exponential thick disc, and for its multi-component representation as the superposition of three Miyamoto-Nagai discs. A useful general formula for the numerical evaluation of the gravitational potential of factorised thick discs is finally given.

description: Employing simplified models in computer simulation is on the one hand often enforced by computer time limitations but on the other hand it offers insights into the molecular properties determining a given physical phenomenon. We employ this strategy to the determination of the phase behaviour of quadrupolar fluids, where we study the influence of omitting angular degrees of freedom of molecules via an effective spherically symmetric potential obtained from a perturbative expansion. Comparing the liquid-vapor coexistence curve, vapor pressure at coexistence, interfacial tension between the coexisting phases, etc., as obtained from both the models with the full quadrupolar interactions and the (approximate) isotropic interactions, we find discrepancies in the critical region to be typically (such as in the case of carbon dioxide) of the order of 4%. However, when the Lennard-Jones parameters are rescaled such that critical temperatures and critical densities of both models coincide with the experimental results, almost perfect agreement between the above-mentioned properties of both models is obtained. This result justifies the use of isotropic quadrupolar potentials. We present also a detailed comparison of our simulations with a combined integral equation/density functional approach and show that the latter provides an accurate description except for the vicinity of the critical point.

description: In this article we review the problem of reaction annihilation $A+A \rightarrow \emptyset$ on a real lattice in one dimension, where $A$ particles move ballistically in one direction with a discrete set of possible velocities. We first discuss the case of pure ballistic annihilation, that is a model in which each particle moves simultaneously at constant speed. We then review ballistic annihilation with superimposed diffusion in one dimension. This model consists of diffusing particles each of which diffuses with a fixed bias, which can be either positive or negative with probability $1/2$, and annihilate upon contact. When the initial concentration of left and right moving particles is same, the concentration $c(t)$ decays as $t^{-1/2}$ with time, for pure ballistic annihilation. However when the diffusion is superimposed decay is faster and the concentration $c(t) \sim t^{-3/4}$. We also discuss the nearest-neighbor distance distribution as well as crossover behavior.

description: The optimizations with respect to the supply chain management have far-reaching effects on enterprise development as well as people’s livelihood. By this fact, it is important to solve the order allocation problem in a real scenario. We focus on optimising a supply marketing order allocation problem (SMOAP) with various constraints from an algorithmic aspect. The SMOAP considers how to match the orders between purchasers and suppliers to maximise the platform’s benefits. We first formulate it as a constrained optimisation problem and then prove that SMOAP is NP-hard. The formulation describes a new trading mode with bundle discounts, time consistency and transportation cost in a real scenario. Based on this trading mode, satisfiability modulo theories (SMT) and constraint programming (CP) optimisers are performed to gain efficient solutions. Moreover, we further propose a tabu search (TS) with two-level perturbation mechanism, score-based heuristic and preprocessing techniques to search for promising solutions. The efficiency of our approaches is confirmed by experiments on real data instances from an electronic commerce trading platform in Jiutai district of Changchun city, Jilin province, China. Experimental results reveal that the proposed method is quite effective.

description: We provide a systematic analysis of finite-temperature magnetic properties of random alloys Fe$_x$Ni$_{1-x}$ with the face-centered-cubic structure over a broad concentration range $x$. By means of the spin-polarized relativistic Korringa-Kohn-Rostoker method we calculate the electronic structure of disordered iron-nickel alloys and discuss how a composition change affects magnetic moments of Fe and Ni and the density of states. We investigate how the Curie temperature depends on Fe concentration using conventional approaches, such as mean-field approximation or Monte Carlo simulations, and dynamic spin-fluctuation theory. Being devised to account for spin fluctuations explicitly, the latter method shows the best fit to experimental results.

Characterization of Carbonic Anhydrases in Models of Neuronal Differentiation and in the Nematode Caenorhabditis elegans

description: CA IX is a member of the carbonic anhydrase family of enzymes. It is a well known marker of hypoxia and it is involved in pH and survival regulation in hypoxic cells. The main aim of my PhD project was to identify molecular interactors of CA IX and, based on the knowledge of its ligands, to contribute to functional characterization of CA IX in neuronal cells.
A complex protein network of novel CA IX interactors has been highlighted: several proteins of the nucleo-cytoplasmatic machinery have been found to bind CA IX under hypoxic condition; many of the CA IX protein interactors belong to the family of the ARM and HEAT-repeat containing proteins. Both in normoxic and hypoxic conditions CA IX also interacts with Cullin-associated NEDD8-dissociated protein 1 (CAND1), which is a nuclear HEAT/ARM-containing protein that is involved in gene transcription and assembly of the SCF E3 ubiquitine ligase complexes.
Immunofluorescence (IF) analysis demonstrated an accumulation of CA IX in the nuclei of neuroblastoma cell lines and in neurons derived from murine ESCs. Putative NLS/NES sequences were identified in the CA IX protein sequence; IF analysis showed that they were able to affect distribution of the reporter protein GFP inside the cell.
Collectively, these data suggest that subcellular localization and functions of CA IX are more complex than previously thought. CA IX may have intracellular functions different from those already known at the plasma membrane. A nuclear function for CA IX is in fact suggested by its localization on transcribed chromatin.
Finally, the nematode Caenorhabditis elegans was used as an animal model, in order to characterize the function of two carbonic anhydrases of the worm, namely, cah-5 and cah-6, during hypoxic and anoxic stresses. Although preliminary, the observed phenotypes allow to predict fundamental roles for carbonic anhydrases in vivo.

description: Although rare, massive stars, being the main sources of ionizing radiation, chemical enrichment and mechanical energy in the Galaxy, are the most important objects of the stellar population. This review presents the many different aspects of the main tool used to study these stars, i.e. spectroscopy. The first part consists in an introduction on these objects and their physical properties (mass, wind, evolution, relation with their environment). Next, the spectral behaviour of single massive stars is investigated, in the visible as well as in the X-ray domain. Finally, the last part of this paper deals with massive binaries, especially those exhibiting a colliding wind phenomenon.

description: The mechanism of spin-phonon coupling in high-T$_C$ copper oxides is explored from band calculations on La$_{(2-x)}$Sr$_x$CuO$_4$ and HgBa$_2$CuO$_4$ systems. The LMTO band calculations, based on the local density approximation, are made for cells containing frozen phonon displacements and/or spin waves within the CuO plane. The virtual crystal approximation is used for studies of hole doped systems. The main result is that phonons are favorable for spin waves and vice-versa, and that pseudogaps appear naturally in the band structures of striped materials with strong SPC. The qualitative results are compatible with many observations showing that the properties of high-T$_C$ superconductors depend both on lattice interactions and magnetic fluctuations. The band results are used to model various properties, mainly of the normal state, such as isotope effects, pseudogaps, Fermi surface broadening, T-dependence of the pseudogap, phonon softening and some aspects of superconductivity. The possibility of perpendicular SPC is investigated, partly by the use of a nearly free electron model.

description: We present a novel framework to solve simultaneously the electroweak hierarchy problem and the strong-CP problem. A small but finite Higgs vacuum expectation value and a small $θ$-angle are selected after the QCD phase transition, without relying on the Peccei-Quinn mechanism or other traditional solutions. We predict a distinctive pattern of correlated signals at hadronic EDM, fuzzy dark matter and axion experiments.

From $ε$-entropy to KL-entropy: Analysis of minimum information complexity density estimation

description: We consider an extension of $ε$-entropy to a KL-divergence based complexity measure for randomized density estimation methods. Based on this extension, we develop a general information-theoretical inequality that measures the statistical complexity of some deterministic and randomized density estimators. Consequences of the new inequality will be presented. In particular, we show that this technique can lead to improvements of some classical results concerning the convergence of minimum description length and Bayesian posterior distributions. Moreover, we are able to derive clean finite-sample convergence bounds that are not obtainable using previous approaches.

Impact of non-Poisson activity patterns on spreading processes

description: Halting a computer or biological virus outbreak requires a detailed understanding of the timing of the interactions between susceptible and infected individuals. While current spreading models assume that users interact uniformly in time, following a Poisson process, a series of recent measurements indicate that the inter-contact time distribution is heavy tailed, corresponding to a temporally inhomogeneous bursty contact process. Here we show that the non-Poisson nature of the contact dynamics results in prevalence decay times significantly larger than predicted by the standard Poisson process based models. Our predictions are in agreement with the detailed time resolved prevalence data of computer viruses, which, according to virus bulletins, show a decay time close to a year, in contrast with the one day decay predicted by the standard Poisson process based models.

MG1-688432: A Peculiar Variable System

description: The short period variable star MG1-688432 has been discovered to exhibit occasional extremely high energy optical outbursts as high as 10^31 joules. Outbursts are typically of several hours duration. These events are often highly structured, resembling sequential associated releases of energy. Twenty years of time sequence photometry is presented, indicating a basic sinusoidal light curve of mean period 6.65d, with some phase shifting and long-term temporal trends in amplitude and mean brightness. Spectroscopy reveals a peculiar star, best resembling a K3 subgiant that has evolved off the main sequence moderately red-ward of the giant branch. Spectroscopic and radial velocity analyses indicate a binary system orbiting its barycenter with an unseen companion to the K3IV primary. This is not an eclipsing system with the inclination of the orbit precluding eclipse by the secondary. The system is at a distance of 1.5kpc and analysis of GAIA observations leads to the conclusion that the HR diagram position of MG1-688432 is established by an intrinsic feature of the system, most likely either the stellar evolutionary state of the observed star or the presence of small (non-gray) dust within the system. Two mechanisms that might give rise to the system are 1) impacts with tidally disrupted planetary debris, and 2) magnetically induced chromospheric activity. An intriguing idea that requires further investigation suggests that the unseen companion is perhaps a white dwarf star which has encountered a planet and tidally shredded it to produce a debris and dust veil that modulates the brightness of the primary.

description: In this article we consider the anisotropic Calderon problem and related inverse problems. The approach is based on limiting Carleman weights, introduced in Kenig-Sjoestrand-Uhlmann (Ann. of Math. 2007) in the Euclidean case. We characterize those Riemannian manifolds which admit limiting Carleman weights, and give a complex geometrical optics construction for a class of such manifolds. This is used to prove uniqueness results for anisotropic inverse problems, via the attenuated geodesic X-ray transform. Earlier results in dimension $n \geq 3$ were restricted to real-analytic metrics.

description: We show that an additional triplet component of the order parameter is generated in the vortex phase of the d-wave superconductor. Spatial variations of the triplet component are analyzed for a strong spin-orbit coupling. Corrections to the London equation and an unusual temperature dependence of the upper critical field, are obtained in the case of the weak spin-orbit coupling.

Emulsifiable oils
Corrugated ducts

description: Recent corrosion problems worldwide have brought increased attention to the issues of durability and corrosion resistance of post-tensioned tendons. While the overall experience in the United States has been good, there is a desire to implement further measures to ensure the adequate protection of post-tensioning systems. This thesis is part of a broad research program evaluating both temporary and long-term corrosion protection solutions. In particular, this thesis addresses the effect of emulsifiable oils used for temporary corrosion protection on bond in multi-strand post-tensioning tendons. The effect of duct type on bond behavior is also investigated. Overall findings indicate that while the force developed by oiled strands is satisfactory, the reduced adhesion between the steel and the grout results in excessive slip. Additionally, galvanized steel pipes tended to allow the grout to slip relative to the duct or the duct to slip relative to the concrete at significantly reduced loads. Corrugated ducts eliminated this slip. Of the corrugated ducts, galvanized metal ducts provided somewhat better bond performance than high density polyethylene ducts.
Thermal buckling transition of crystalline membranes in a field

description: Two dimensional crystalline membranes in isotropic embedding space exhibit a flat phase with anomalous elasticity, relevant e.g., for graphene. Here we study their thermal fluctuations in the absence of exact rotational invariance in the embedding space. An example is provided by a membrane in an orientational field, tuned to a critical buckling point by application of in-plane stresses. Through a detailed analysis, we show that the transition is in a new universality class. The self-consistent screening method predicts a second order transition, with modified anomalous elasticity exponents at criticality, while the RG suggests a weakly first order transition.
