description: The aim of this study was to investigate the psychological reactions in Ebola Virus Disease (EVD) survivors following their discharge from the MSF Ebola Treatment Center (ETC) in Sierra Leone.

Survivors have experienced a potentially traumatizing experience as inpatients. They have faced a life threatening event, have witnessed significant suffering and death (often their own family) and most have been hospitalized for a significant length of time (median length of stay 12.5 days for survivors compared to non-survivors stay of 4 days).The prevalence of post trauma responses observed in EVD survivors was found to be typical of those documented in studies of victims of more conventional traumatic events. Although the emergency context limited the scope of this study, it does for the first time demonstrate the need to consider the significant likelihood of post treatment psychological sequellae in EVD survivors.

description: The impact of momentum anisotropy on the heavy quark transport coefficients due to collisional and radiative processes in the QCD medium has been studied within the ambit of kinetic theory. Anisotropic aspects (momentum) are incorporated into the heavy quark dynamics through the non-equilibrium momentum distribution function of quarks, antiquarks, and gluons. These non-equilibrium distribution functions that encode the physics of momentum anisotropy and turbulent chromo-fields have been obtained by solving the ensemble-averaged diffusive Vlasov-Boltzmann equation. The momentum dependence of heavy quark transport coefficients in the medium is seen to be sensitive to the strength of the anisotropy for both collisional and radiative processes. In addition, the collisional and radiative energy loss of the heavy quark in the anisotropic hot QCD medium have been analyzed. The effects of anisotropy on the drag and diffusion coefficients are observed to have a visible impact on the nuclear suppression factor both at the RHIC and LHC.

description: Our previous work on quantum kinematics and coherent states over finite configuration spaces is extended: the configuration space is, as before, the cyclic group Z_n of arbitrary order n=2,3,..., but a larger group - the non-Abelian dihedral group D_n - is taken as its symmetry group. The corresponding group related coherent states are constructed and their overcompleteness proved. Our approach based on geometric symmetry can be used as a kinematic framework for matrix methods in quantum chemistry of ring molecules.

description: We present here the results relating to the ultracool regime within 100pc from the Gaia Catalogue of Nearby Stars, published as a science verification paper of the recent Gaia early data release 3. We provide updated evidence for the stellar/ substellar boundary being around L3 via the volume limited luminosity function. We estimate completeness of Gaia and show how thousands of new ultracool dwarf candidates have been selected.

description: Adult amphibians and their larvae occur in a wide range of habitats, from tree hollows, streams to permanent ponds. Extant amphibians (Lissamphibia) evolved from ancestors that inhabited lentic environments. However, some derived lineages (Neobatrachia) invaded lotic environments. This adaptive radiation to occupy lotic environments within Neobatrachia may have promoted an acceleration of body shape diversification to cope with a new hydrodynamics and hydroperiod. Here, we tested whether the rate of body shape evolution varies between ponds and streams using the multivariate Brownian Motion model. We also estimated the macroevolutionary adaptive landscape of tadpole body shape. We used geometric morphometrics along with phylogenetic comparative methods for multivariate data to measure the larval shape of 54 species from 11 families. We used an average of 10 individuals of each species between Gosner stages 34-40. We use a consensus of Jetz & Pyron 2018 phylogeny. Stream-dwelling species had a higher rate of evolution than those occurring in ponds, but this difference was not significant. However, there was a wide variation in the rates of evolution within lineages that occur in each environment. We found three adaptive peaks, two of them containing species exclusive of stream or pond, and a third ancestral regime shared by most species. In this regime, there is a wide variety of shapes and habitats, which makes the adaptive landscape difficult to interpret. Increased rates of evolution in stream tadpoles suggest greater morphological diversification in these environments due to higher selective pressures. However, the heterogeneity of evolutionary rates within lineages indicates that body shape appears to be influenced by factors other than the environment.

Effect of Redshift Distributions of Fast Radio Bursts on Cosmological Constraints

description: Nowadays, fast radio bursts (FRBs) have been a promising probe for astronomy and cosmology. However, it is not easy to identify the redshifts of FRBs to date. Thus, no sufficient actual FRBs with identified redshifts can be used to study cosmology currently. In the past years, one has to use the simulated FRBs with "known" redshifts instead. To simulate an FRB, one should randomly assign a redshift to it from a given redshift distribution. But the actual redshift distribution of FRBs is still unknown so far. Therefore, many redshift distributions have been assumed in the literature. In the present work, we study the effect of various redshift distributions on cosmological constraints, while they are treated equally. We find that different redshift distributions lead to different cosmological constraining abilities from the simulated FRBs. This result emphasizes the importance to find the actual redshift distribution of FRBs, and reminds us of the possible bias in the FRB simulations due to the redshift distributions.

Gluonic Pole Cross Sections and Single Spin Asymmetries in Hadron-Hadron Scattering

description: The gauge-links connecting the parton field operators in the hadronic matrix elements appearing in the transverse momentum dependent distribution functions give rise to T-odd effects. Due to the process-dependence of the gauge-links the T-odd distribution functions appear with different pre-factors. A consequence is that in the description of single spin asymmetries the parton distribution and fragmentation functions are convoluted with gluonic pole cross sections rather than the basic partonic cross sections. In this paper we calculate the gluonic pole cross sections encountered in single spin asymmetries in hadron-hadron scattering. The case of back-to-back pion production in polarized proton-proton scattering is worked out explicitly. It is shown how T-odd gluon distribution functions originating from gluonic pole matrix elements appear in twofold.

Αρχικά, μελετώντας τις βασικές ιδιότητες των σειρών Dirichlet εξετάζουμε την σημειακή σύγκλιση, απόλυτη σύγκλιση και ομοιόμορφη σύγκλιση των σειρών, ενώ παράλληλα ορίζουμε τις αντίστοιχες τετμημένες (τετμημένη σύγκλισης, τετμημένη απόλυτης σύγκλισης, τετμημένη ομοιόμορφης σύγκλισης), αποδεικνύοντας τύπους για τον υπολογισμό τους (τύποι Cahen-Bohr). Έπειτα, εξετάζουμε τις αναλυτικές και αλγεβρικές ιδιότητες των συναρτήσεων που ορίζονται από μια σειρά Dirichlet. Ακολούθως, μελετώντας γενικότερες ιδιότητες των σειρών Dirichlet, αποδεικνύουμε τον τύπο του Perron, την ιδιότητα του Μέσου Όρου -μία ταυτότητα τύπου Parseval- όπως επίσης, ένα θεώρημα μοναδικότητας της αναπαράστασης μιας συνάρτησης από σειρά Dirichlet. Κλείνοντας, στο τελευταίο κεφάλαιο, παραθέτουμε χώρους Hilbert σειρών Dirichlet, ανάλογων των κλασικών χώρων Hardy, Dirichlet και Bergman του μοναδιαίου δίσκου, μελετώντας τους ως προς τους σημειακούς πολλαπλασιαστές τους.
description: The aim of the thesis is to study the ordinary Dirichlet series as well as the pointwise multipliers of Hilbert spaces whose functions have a Dirichlet series representation. Initially, by studying the basic properties of the Dirichlet series, we examine the convergence, absolute convergence and uniform convergence of the series, while defining the corresponding abscissae (abscissa of convergence, abscissa absolute of convergence, abscissa of uniform convergence), proving formulas for their calculation (Cahen-Bohr formulae ). We also examine the analytical and algebraic properties of the functions defined by a Dirichlet series. Then, while studying the more general properties of the Dirichlet series, we demonstrate the Peron formula, the Mean Value property - a Parseval type identity - as well as a theorem of uniqueness of the representation of a Dirichlet series. Finally, in the last chapter of the thesis, we list Hilbert spaces of Dirichlet series, analogue to the classical Hardy, Dirichlet and Bergman spaces of the unit disk, examining their pointwise multipliers.

description: Classification is an important goal in many branches of mathematics. The idea is to describe the members of some class of mathematical objects, up to isomorphism or other important equivalence in terms of relatively simple invariants. Where this is impossible, it is useful to have concrete results saying so. In model theory and descriptive set theory, there is a large body of work, showing that certain classes of mathematical structures admit classification, while others do not. In the present paper, we describe some recent work on classification in computable structure theory.

description: We theoretically investigated the Floquet states of bilayer graphene heterostructure under the irradiation by horizontally incident circular polarized light. The in-plane and out-of-plane electric field of the light periodically perturbs the intra-layer and inter-layer hopping, respectively. For circular polarized light, the two components of the electric field has $π/2$ phase difference, so that the two types of hopping are periodically perturbed with the $π/2$ phase difference, which modify the effective inter-layer hopping. We focus on the model of bilayer graphene in the heterostructure of antiferromagnetic van der Walls spin valve. The amplitude of the irradiation can tune the band gap and topological properties of the bulk state. The spin-polarized quantum anomalous Hall phase with Chern number being one is predicted. The incident angle of the irradiation can tune the band gap and dispersion of the edge states in zigzag nanoribbons.

description: We present a density-functional theory study addressing the on-surface adsorption of oxygen at the Pd(11N) (N =3,5,7) vicinal surfaces, which exhibit (111) steps and (100) terraces of increasing width. We find the binding to be predominantly governed by the local coordination at the adsorption site. This leads to very similar bonding properties at the threefold step sites of all three vicinal surfaces, while the binding at the central fourfold hollow site in the four atomic row terrace of Pd(117) is already very little disturbed by the presence of the neighboring steps.

Universal superdiffusive modes in charged two dimensional liquids

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

description: Using a hydrodynamic approach, we show that charge diffusion in two dimensional Coulomb interacting liquids with broken momentum conservation is intrinsically anomalous. The charge relaxation is governed by an overdamped, superdiffusive plasmon mode. We demonstrate that the diffusing particles follow Lévy flight trajectories, and study the hydrodynamic collective modes under the influence of magnetic fields. The latter are shown to slow down the superdiffusive process. The results are argued to be relevant to electron liquids in solids, as well as plasmas.

description: The project we have been working on is concerned with the activity
 and evolution of exoplanet hosting stars.
 The hypothesis we were exploring is that close-in, more massive exoplanets
 may influence the rotation evolution of the host in particular,
 making the stellar host more active than expected for given age and SpT.
 To avoid the dependence on age in estimating the expected activity level,
 we only investigated planet-hosting stars that have a stellar companion,
 which we used as a reference for the expected activity level
 (assuming ofc that they formed at approx the same time and from the same interstellar cloud).
 As the activity indicator, we used the X-ray Luminosity
 which accounts for the activity of the stellar corona.
 Although the sample does not allow for a definite conclusion
 our results point us to a positive correlation between
 the activity level of the planet host and the strength of the SPI.

Τέλος, διαπιστώσαμε ότι παρά τις ασήμαντες διαφοροποιήσεις το ρουμανικό Ιερατικό μας παραδίδει την τελετουργία της θείας Λειτουργίας σύμφωνα με τα διορθοδόξως κρατούντα. Οι ελάχιστες διαφοροποιήσεις είναι ασήμαντου χαρακτήρα και δεν το διαφοροποιούν σε σχέση με τα αντίστοιχα λειτουργικά βιβλία της υπόλοιπης ορθόδοξης οικογένειας.
description: In the present study we dealt with the presentation of the history of the modern revised Hieratiko book and we have seen that constant efforts are being made to improve its content and its form. The improvements relate to issues of language and interpretation, especially those of Greek or Slavic origin on terms of Romanian origin, on the modernization of the Divine Liturgy, especially when it comes to a priestly collector. Finally, we have found that despite the insignificant variations, the Romanian Priest gives us the ritual of the Divine Liturgy according to the transcendental statutes. The least variations are insignificant and do not differentiate them from the corresponding functional books of the rest of the Orthodox family.

description: We formulate the third harmonic generation (THG) within the dynamical mean field theory (DMFT) approximation of the Hubbard model. In the limit of large dimensions, where DMFT becomes exact, the vertex corrections to current vertices are identically zero, and hence the calculation of the THG spectrum reduces to a time-ordered convolution, followd by appropriate analytic continuuation. We present the typical THG spectrum of the Hubbard model obtained by this method. Within our DMFT calculation, we observe a nontrivial approximate {\em scaling} function describing the THG spectra in all Mott insulators, independent of the gap magnitude.

description: The \emph{index set} of a computable structure $\mathcal{A}$ is the set of indices for computable copies of $\mathcal{A}$. We determine the complexity of the index sets of various mathematically interesting structures, including arbitrary finite structures, $\mathbb{Q}$-vector spaces, Archimedean real closed ordered fields, reduced Abelian $p$-groups of length less than $ω^{2}$, and models of the original Ehrenfeucht theory. The index sets for these structures all turn out to be $m$-complete $Π_{n}^{0}$, $d$-$Σ_{n}^{0}$, or $Σ_{n}^{0}$, for various $n$. In each case, the calculation involves finding an \textquotedblleft optimal\textquotedblright% \ sentence (i.e., one of simplest form) that describes the structure. The form of the sentence (computable $Π_{n}$, $d$-$Σ_{n}$, or $Σ_{n}$) yields a bound on the complexity of the index set. When we show $m$% -completeness of the index set, we know that the sentence is optimal. For some structures, the first sentence that comes to mind is not optimal, and another sentence of simpler form is shown to serve the purpose. For some of the groups, this involves Ramsey theory.
Modelling X-ray and radio emission from a flaring T-Tauri star

Radio emission

description: T-Tauri stars exhibit strong flaring activity. These flares are over-luminous in radio compared with X-rays, deviating from the well-known Gudel-Benz relation. This has been previously been interpreted by considering the flares to take place in large loops interacting with the inner radius of the accretion disk, with gyrosynchrotron emission mainly from a population of non-thermal electrons created by magnetic reconnection (Waterfall et al, Mon. Not. Roy Ast. Soc., 483, 917, 2019). We present new results of time-dependent modelling of the radio emission from a flaring T-Tauri star, using three-dimensional magnetohydrodynamic simulations combined with a model for non-thermal electrons in magnetic loops and radiative transfer modelling of the gyrosynchrotron emission (Waterfall et al, Mon. Not. Roy Ast. Soc., 496, 2715, 2020. We predict the multi-frequency (1 - 1000 GHz) time variation intensity and circular polarisation of the radio emission. We show that observations of the time varying spectrum and polarisation could place important constraints on the physical properties of the flare environment and the accretion process.

description: Since 2012 the GAPS (Global Architecture of Planetary Systems) project at the Telescopio Nazionale Galileo (TNG) involves a large part of the Italian community working on exoplanetary science. In the first five years, the project was based on radial velocity (RV) surveys with the HARPS-N@TNG spectrograph and was focused on the search and characterization of planetary systems around stars with different properties. In 2017, thanks to the integration of GIARPS (GIANO-B & HARPS-N) at the TNG, the GAPS2 project started to explore the origin and the diversity of planetary systems adopting a twofold approach: the observation of planetary atmospheres and the detection/study of planets around young stars. The current literature suggests that we should expect a large fraction of hot Jupiters around very young stars with respect to the old ones, but the available statistic is poor and based on claimed detections still not confirmed by independent investigations. The observation of planets around young objects is therefore important because it allows us to study the ongoing planet formation, helping to investigate the role played by the formation sites, the migration mechanisms, and the orbit evolution.
The consequences of hesitation: Axelrod model with intrinsic noise

description: We study the influence of hesitating agents in the Axelrod model by introducing an intrinsic noise, which is proportional to the disagreement between the interacting agents, and thus coupled to the dynamics. Our results show that, unlike the effect of the cultural drift where the noise is just controlled by an external parameter, the intrinsic noise never allows the system to reach a frozen state in the thermodynamic limit. Moreover, we show that when the intrinsic noise affects the agents' variables, the system's behaviour is also different from the case when it affects the network of their interactions.

description: We develop a method for computing the Bogoliubov transformation experienced by a confined quantum scalar field in a globally hyperbolic spacetime, due to the changes in the geometry and/or the confining boundaries. The method constructs a basis of solutions to the Klein-Gordon equation associated to each compact Cauchy hypersurface of constant time. It then provides a differential equation for the linear transformation between bases at different times. The transformation can be interpreted physically as a Bogoliubov transformation when it connects two regions in which a time symmetry allows for a Fock quantisation. This second article on the method is dedicated to spacetimes with timelike boundaries that do not remain static in any synchronous gauge. The method proves especially useful in the regime of small perturbations, where it allows one to easily make quantitative predictions on the amplitude of the resonances of the field. Therefore, it provides a crucial tool in the growing research area of confined quantum fields in table-top experiments. We prove this utility by addressing two problems in the perturbative regime: Dynamical Casimir Effect and gravitational wave resonance. We reproduce many previous results on these phenomena and find novel results in an unified way. Possible extensions of the method are indicated. We expect that our method will become standard in quantum field theory for confined fields.

description: Consider $n$ i.i.d. random vectors on $\mathbb{R}^2$, with unknown, common distribution function $F$. Under a sharpening of the extreme value condition on $F$, we derive a weighted approximation of the corresponding tail copula process. Then we construct a test to check whether the extreme value condition holds by comparing two estimators of the limiting extreme value distribution, one obtained from the tail copula process and the other obtained by first estimating the spectral measure which is then used as a building block for the limiting extreme value distribution. We derive the limiting distribution of the test statistic from the aforementioned weighted approximation. This limiting distribution contains unknown functional parameters. Therefore, we show that a version with estimated parameters converges weakly to the true limiting distribution. Based on this result, the finite sample properties of our testing procedure are investigated through a simulation study. A real data application is also presented.

description: For the first time, the reaction gamma d -> Lambda n K+ has been analyzed in order to search for the exotic pentaquark baryon Theta+(1540). The data were taken at Jefferson Lab, using the Hall-B tagged-photon beam of energy between 0.8 and 3.6 GeV and the CEBAF Large Acceptance Spectrometer (CLAS). No statistically significant structures were observed in the nK+ invariant mass distribution. The upper limit on the gamma d -> Lambda Theta+ integrated cross section has been calculated and found to be between 5 and 25 nb, depending on the production model assumed. The upper limit on the differential cross section is also reported.

description: We show that the random point measures induced by vertices in the convex hull of a Poisson sample on the unit ball, when properly scaled and centered, converge to those of a mean zero Gaussian field. We establish limiting variance and covariance asymptotics in terms of the density of the Poisson sample. Similar results hold for the point measures induced by the maximal points in a Poisson sample. The approach involves introducing a generalized spatial birth growth process allowing for cell overlap.

description: The aim of the present master thesis is the study of postcolonial theory in the example of the novel of the French speaking author A. Abdourahman Waberi “In den Vereinigten Staaten von Afrika“ and the novella of the German speaking author Jonas Lüscher “Frühling der Barbaren“. For this purpose, after an overview of the main terms regarding colonialism, we presented the fundamental theoretical approaches that constitute the core of postcolonial studies. We examined then the conceptual, narrative and stylistic devices of the books, in order to trace through this detailed literary analysis elements of postcolonial studies in them.

EV Lacertae

description: We acquired data of nearby dM3.5e star EV Lac using 5 different observatories: NASA's TESS mission, NASA's Neil Gehrels Swift Observatory ($Swift$), NASA's Neutron Interior Composition Explorer (NICER) and two ground based telescopes (University of Hawaii 2.2-m (UH88) and Las Cumbres Observatory Global Telescope (LCOGT) Network), to span a comprehensive, simultaneous wavelength coverage of flaring events. We identified 56 flares in the TESS light curve, 9 flares in the $Swift$ $UVM2$ light curve, 14 flares in the NICER X-ray light curve, and 1 flare in the LCOGT light curve. However, we did not identify flares in the $Swift$ XRT light curve or UH88 spectrum. We compare flare frequency distribution (FFD) of flares observed by TESS, NICER and $Swift$/UVOT. We find that the FFDs of TESS and NICER flares have comparable slopes, $\beta_{T}$ = -0.67$\pm$0.09 and $\beta_{N}$ = -0.64$\pm$0.19, and that the FFD of UVOT flares has a shallower slope ($\beta_{U}$ = -0.38$\pm$0.13).
