description: We study the dating market decision problem in which men and women repeatedly go out on dates and learn about each other. We consider a model for the dating market that takes into account progressive mutual learning. This model consists of a repeated game in which agents gain an uncertain payoff from being matched with a particular person on the other side of the market in each time period. Players have a list of preferred partners on the other set. The players that reach higher rank levels on the other set preferences list have also higher probability to be accepted for dating. A question can be raised, as considered in this study: Can the less appreciated players do better? Two different kinds of dating game are combined "a la Parrondo" to foster the less attractive players. Optimism seems to be highly recommendable, especially for losers.

description: We demonstrate a light-pulse atom interferometer based on the diffraction of free-falling atoms by a picosecond frequency-comb laser. More specifically, we coherently split and recombine wave packets of cold $^{87}$Rb atoms by driving stimulated Raman transitions between the $|5s~^2S_{1/2},F=1\rangle$ and $|5s~^2S_{1/2},F=2\rangle$ hyperfine states, using two trains of picosecond pulses in a counter-propagating geometry. We study the impact of the pulses length as well as of the interrogation time onto the contrast of the atom interferometer. Our experimental data are well reproduced by a numerical simulation based on an effective coupling which depends on the overlap between the pulses and the atomic cloud. These results pave the way for extending light-pulse interferometry to transitions in other spectral regions and therefore to other species, for new possibilities in metrology, sensing of gravito-inertial effects and tests of fundamental physics.

description: Quantum spin liquids (QSLs), in which spins are highly entangled, have been considered a groundwork for generating exotic superconductivity.Despite numerous efforts, superconductivity emerging from QSLs has been unrealized in actual materials due to the difficulties in stabilizing QSL states with metallic conductivity.Recently, an organic compound, $κ$-(BEDT-TTF)$_4$Hg$_{2.89}$Br$_8$, with a nearly regular triangular lattice of molecular dimers was recognized as a candidate for doped QSLs. In this study, we report an unusual superconducting phase of $κ$-(BEDT-TTF)$_4$Hg$_{2.89}$Br$_8$: unexpectedly large ratios of the upper critical field to the critical temperature $H_{\rm c2}$/$T_{\rm c}$ in fields not only parallel but also perpendicular to the two-dimensional conducting layers and a very wide region of fluctuating superconductivity above $T_{\rm c}$.Our results reveal that these peculiarities arise from strong electron correlations and possible quantum criticality unique to the doped QSL state, leading to a heavy mass of itinerant carriers and a large superconducting energy gap.

Τα ζώα χωρίστηκαν σε δυο ομάδες, την ομάδα Α(n=19) και την ομάδα Β(n=16), στις οποίες ανήκουν, αντίστοιχα, τα κυναριά με αυξημένη και εντός των φυσιολογικών ορίων τιμή της CPLI. Τα ασθενή ζώα υποβάλλονταν σε καθημερινή κλινική εξέταση. Δείγματα αίματος λαμβάνονταν με σκοπό τη διενέργεια γενικής εξέτασης αίματος και προσδιορισμός της δραστηριότητας της αμυλάσης και της λιπάσης στον ορό του αίματος (κάθε 24 ώρες), καθώς και για τη διενέργεια συνήθων βιοχημικών εξετάσεων (κάθε 48 ώρες). Ο προσδιορισμός της συγκεντρώσεως της θρυψίνης και του θρυψιγόνου (Canine Trypsin Like Immunoreactivity) και της CPLI διενεργήθηκε σε κάθε κυνάριο τρει φορές. Σε όλα τα ζώα πραγματοποιήθηκε υπερηχοτομογραφική εξέταση του παγκρέατος. Σε περίπτωση θανάτου πραγματοποιούνταν ιστοπαθολογική εξέταση ιστοτεμαχιών του παγκρέατος και του λεπτού εντέρου. Υπερλιπασαιμία εμφάνισαν τα 29/35 (83%) κυναριά. Στα 16/19 κυναριά της ομάδας Α διαπιστώθηκαν τιμές της λιπάσης που ξεπέρασαν το τριπλάσιο της ανώτερης φυσιολογικής τιμής. Τα 19/35 (54%) κυνάρια εμφάνισαν αυξημένες τιμές του CPLI. Σε 5 κυνάρια της ομάδας Α διαπιστώθηκε ενδοπεριτοναϊκή συλλογή με αυξημένη τη δραστηριότητα της λιπάσης σε αυτή. Υπερηχοτομογραφικά ευρήματα ΟΠ διαπιστώθηκαν σε 4/9 κυναριά της ομάδας Α. Ιστοπαθολογικές αλλοιώσεις παρατηρήθηκαν σε 5 κυνάρια της ομάδας Α.
description: The aim of the present study was to evaluate the prevalence of acute pancreatitis (AP), based on the CPLI assay (Canine Pancreatitis Lipase Immunoreactivity), in 35 young dogs with parvovirous enteritis (CPV-2). The dogs were divided in two groups; group A (n=19) and group b (b=16), were constisted of dogs with increased and normal cPLI valves, respectively. A complete physical examination was performed daily. Blood samples were collected for complete blood count, serum lipase and amylase determination (every 24 hours) and serum biochemistry profile (every 48 hours). Serum concentration of cTLI (Canine Trypsin Like Immunoreactivity) and cPLI were measured three times in each dog. Ultrasonography of the pancreas was performed in all days. In case of deaths biopsies from the pancreas and small intestine were obtained. Hyperlipasemia was noticed in 29/35 (83%) days. In 16/19 dogs of group A 3 times fold increase in serum lipase activity was demostrated. Serum cPLI concentration increased in 19/35 (54%) dogs. Peritoneal fluid accumulation with high lipase activity was detected in 5 dogs of group A. Ultranographic evidence of AP was revealed in 4/19 dogs of group A. Histopathologic findings of AP were revealed in 5 dogs of group A.

description: The primary research question of the PhD thesis is the analysis and appraisal of important aspects of current conservation policies in Greece. This analysis aims at identifying whether, and to which degree, these policies target and contribute to nature conservation. The common point of the three distinct objects – scientific studies of the PhD thesis is the multilevel examination of the relationship between the natural environment and development, and, more generally, of the relationship of today’s society with nature. The general theoretical context of the PhD thesis is based in the field of political ecology, while the methodological context is based on a combination of empirical evidence based on qualitative social research (in particular on a grounded theory approach) and of findings derived from the systematic study of the scientific literature (chapter 2).

description: We consider discrete quantum systems coupled to finite environments which may possibly consist of only one particle in contrast to the standard baths which usually consist of continua of oscillators, spins, etc. We find that such finite environments may, nevertheless, act as thermostats, i.e., equilibrate the system though not necessarily in the way predicted by standard open system techniques. Thus, we apply a novel technique called the Hilbert space Average Method (HAM) and verify its results numerically.

description: We investigate theoretically the superconducting state of the undoped Fe-based superconductor ThFeAsN. Using input from $ab~initio$ calculations, we solve the Fermi-surface based, multichannel Eliashberg equations for Cooper-pair formation mediated by spin and charge fluctuations, and by the electron-phonon interaction (EPI). Our results reveal that spin fluctuations alone, when coupling only hole-like with electron-like energy bands, can account for a critical temperature $T_c$ up to $\sim7.5\,\mathrm{K}$ with an $s_{\pm}$-wave superconducting gap symmetry, which is a comparatively low $T_c$ with respect to the experimental value $T_c^{\mathrm{exp}}=30\,\mathrm{K}$. Other combinations of interaction kernels (spin, charge, electron-phonon) lead to a suppression of $T_c$ due to phase frustration of the superconducting gap. We qualitatively argue that the missing ingredient to explain the gap magnitude and $T_c$ in this material is the first-order correction to the EPI vertex. In the noninteracting state this correction adopts a form supporting the $s_{\pm}$ gap symmetry, in contrast to EPI within Migdal's approximation, i.e., EPI without vertex correction, and therefore it enhances tendencies arising from spin fluctuations.

description: A geometrical description of the Heisenberg magnet (HM) equation with classical spins is given in terms of flows on the quotient space $G/H_+$ where $G$ is an infinite dimensional Lie group and $H_+$ is a subgroup of $G$. It is shown that the HM flows are induced by an action of $\mathbb{R}^2$ on $G/H_+$, and that the HM equation can be integrated by solving a Birkhoff factorization problem for $G$. For the HM flows which are Laurent polynomials in the spectral variable we derive an algebraic transformation between solutions of the nonlinear Schroedinger (NLS) and Heisenberg magnet equations. The Birkhoff factorization for $G$ is treated in terms of the geometry of the Segal-Wilson Grassmannian $Gr(H)$. The solution of the problem is given in terms of a pair of Baker functions for special subspaces of $Gr(H)$. The Baker functions are constructed explicitly for subspaces which yield multisoliton solutions of NLS and HM equations.

Entropic and trace distance based measures of non-Markovianity

description: We analyze and compare different measures for the degree of non-Markovianity in the dynamics of open quantum systems. These measures are based on the distinguishability of quantum states which is quantified, on the one hand, by the trace distance or, more generally, by the trace norm of the Helstrom matrix, and, on the other hand, by entropic quantifiers: the Jensen-Shannon divergence, the Holevo or the quantum skew divergence. We explicitly construct a qubit dynamics for which the trace norm based non-Markovianity measure is nonzero, while all the entropic measures turn out to be zero. This leads to the surprising conclusion that the non-Markovianity measure which employs the trace norm of the Helstrom matrix is strictly stronger than all entropic non-Markovianity measures.

description: Galactic and extra-galactic sources produce X-rays that are often absorbed by molecules and atoms in giant molecular clouds (GMCs), which provides valuable information about their composition and physical state. We mimic this phenomenon with a laboratory Z-pinch X-ray source, which is impinged on neutral molecular gas. The novel technique produces a soft X-ray pseudo continuum using a pulsed-current generator. The absorbing gas is injected from a 1 cm long planar gas-puff without any window or vessel along the line of sight. An X-ray spectrometer with a resolving power of $λ/Δλ\sim$420, comparable to that of astrophysical space instruments, records the absorbed spectra. This resolution clearly resolves the molecular lines from the atomic lines; therefore, motivating the search of molecular signature in astrophysical X-ray spectra. The experimental setup enables different gas compositions and column densities. K-shell spectra of CO$_2$, N$_2$ and O$_2$ reveal a plethora of absorption lines and photo-electric edges measured at molecular column densities between $\sim$10$^{16}$ cm$^{-2}$ -- 10$^{18}$ cm$^{-2}$ typical of GMCs. We find that the population of excited-states, contributing to the edge, increases with gas density.

description: We study the problem of underscreened Kondo physics in an interacting electronic system modeled by a Luttiger Liquid (LL). We find that the leading temperature dependence of thermodynamical quantities like the specific heat, spin susceptibility are Fermi Liquid like in nature. However, anomalous power law exponents are seen in the subleading terms. We also discuss possible realizations through single and double quantum dot configurations coupled to LL leads and its consequences for electronic transport. The leading low temperature transport behavior is seen to exhibit in general, non Fermi liquid LL behavior unlike the thermodynamical quantities.

description: LiDARs play a critical role in Autonomous Vehicles' (AVs) perception and their safe operations. Recent works have demonstrated that it is possible to spoof LiDAR return signals to elicit fake objects. In this work we demonstrate how the same physical capabilities can be used to mount a new, even more dangerous class of attacks, namely Object Removal Attacks (ORAs). ORAs aim to force 3D object detectors to fail. We leverage the default setting of LiDARs that record a single return signal per direction to perturb point clouds in the region of interest (RoI) of 3D objects. By injecting illegitimate points behind the target object, we effectively shift points away from the target objects' RoIs. Our initial results using a simple random point selection strategy show that the attack is effective in degrading the performance of commonly used 3D object detection models.

description: The study of the magnetic properties depending upon mechanical milling of the ferromagnetic polycrystalline TbAl_2 material is reported. The Rietveld analysis of the X-ray diffraction data reveals a decrease of the grain size down to 14 nm and -0.15 % of variation of the lattice parameter, after 300 hours of milling time. Irreversibility in the zero field cooled - field cooled (ZFC-FC) DC-susceptibility and clear peaks in the AC susceptibility between 5 and 300 K show that the long-range ferromagnetic structure is inhibited in favour of a disordered spin arrangement below 45 K. This glassy behaviour is also deduced from the variation of the irreversibility transition with the field (H^{2/3}) and frequency. The magnetization process of the bulk TbAl_2 is governed by domain wall thermal activation processes. By contrast, in the milled samples, cluster-glass properties arise as a result of cooperative interactions due to the substitutional disorder. The interactions are also influenced by the nanograin structure of the milled alloys, showing a variation of coercivity with the grain size, below the crossover between the multi- and single-domain behaviours.

description: The tradition of Hindustani Classical Music is age-old. Different forms under this music evolved out of Indian Classical Music in due course time. Raga is the core of Indian Classical Music and the prevailing Cultural tradition as well. Various Classical and Semi-classical Forms of Hindustani Classical Music such as Dhrupad, Dhamar, Khyal, Tappa, Thummri, Tarana etc. had been exercised by the Court-musicians and the Gharana Maestros since from the medieval period in northern India. Gharana, an exclusive feature or system in Hindustani Classical Music, is meant for maintaining the standard and variety. The practice of the same has also meticulously been observed among the Performers and Practitioners belonging to specified Gharanas till the twentieth century. The overall standard as well as the versatility of such music is being found gradually deteriorated in spite of the foundation of numerous institutions under the Department of Higher Education across the country as well as consistent practice and performances among the learners both from institutional and private segments.This paper intends to find the cause of the concurrent problem through proper analysis and the solution at the same time.

description: The black hole candidate X-ray transient XTE J1817-330 was observed by the Swift satellite over 160 days of its 2006 outburst with the XRT and UVOT instruments. At the start of the observations, the XRT spectra show that the 0.6-10 keV emission is dominated by an optically thick, geometrically thin accretion disk with an inner disk temperature of $\sim0.8$ keV, indicating that the source was in a high/soft state during the initial outburst phase. We tracked the source through its decline into the low/hard state with the accretion disk cooling to $\sim 0.2 \mathrm{keV}$ and the inner disk radius consistent with the innermost stable circular orbit at all times. Furthermore, the X-ray luminosity roughly follows $L_X \propto T^4$ during the decline, consistent with a geometrically stable blackbody. These results are the strongest evidence yet obtained that accretion disks do not automatically recede after a state transition, down to accretion rates as low as $0.001 L_{Edd}$. Meanwhile, the near-UV flux does not track the X-ray disk flux, and is well in excess of what is predicted if the near-UV emission is from viscous dissipation in the outer disk. The strong correlation between the hard X-ray flux and the near-UV flux, which scale as $L_X^{0.5}$, indicate that reprocessed emission is most likely the dominate contribution to the near-UV flux. We discuss our results within the context of accretion disks and the overall accretion flow geometry in accreting black holes.

We argue that the superconductivity is not phonon mediated.

description: Supercooled liquid and glassy acetyl salicylic acid was studied using dielectric spectroscopy and deuteron relaxometry in a wide temperature range. The supercooled liquid is characterized by major deviations from thermally activated behavior. In the glass the secondary relaxation exhibits the typical features of a Johari-Goldstein process. Via measurements of spin-lattice relaxation times the selectively deuterated methyl group was used as a sensitive probe of its local environments. There is a large difference in the mean activation energy in the glass with respect to that in crystalline acetyl salicylic acid. This can be understood by taking into account the broad energy barrier distribution in the glass.

description: Y{0.5}$Ca{0.5}BaCo4O7 contains kagome layers of Co ions, whose spins are strongly coupled according to a Curie-Weiss temperature of -2200 K. At low temperatures, T = 1.2 K, our diffuse neutron scattering study with polarization analysis reveals characteristic spin correlations close to a predicted two-dimensional coplanar ground state with staggered chirality. The absence of three dimensional long-range AF order proves negligible coupling between the kagome layers. The scattering intensities are consistent with high spin S=3/2 states of Co2+ in the kagome layers and low spin S=0 states for Co3+ ions at interlayer sites. Our observations agree with previous Monte Carlo simulations indicating a ground state of only short range chiral order.

description: Recently, with the advances made in continuous representation of words (word embeddings) and deep neural architectures, many research works are published in the area of relation extraction and it is very difficult to keep track of so many papers. To help future research, we present a comprehensive review of the recently published research works in relation extraction. We mostly focus on relation extraction using deep neural networks which have achieved state-of-the-art performance on publicly available datasets. In this survey, we cover sentence-level relation extraction to document-level relation extraction, pipeline-based approaches to joint extraction approaches, annotated datasets to distantly supervised datasets along with few very recent research directions such as zero-shot or few-shot relation extraction, noise mitigation in distantly supervised datasets. Regarding neural architectures, we cover convolutional models, recurrent network models, attention network models, and graph convolutional models in this survey.

description: We study entanglement generation via particle transport across a one-dimensional system described by the Bose-Hubbard Hamiltonian. We analyze how the competition between interactions and tunneling affects transport properties and the creation of entanglement in the occupation number basis. Alternatively, we propose to use spatially delocalized quantum bits, where a quantum bit is defined by the presence of a particle either in a site or in the adjacent one. Our results can serve as a guidance for future experiments to characterize entanglement of ultracold gases in one-dimensional optical lattices.

description: Congruent Procrustes analysis aims to find the best matching between two point sets through rotation, reflection and translation. We formulate the Procrustes problem for hyperbolic spaces, review the canonical definition of the center of point sets, and give a closed form solution for the optimal isometry for noise-free measurements. We also analyze the performance of the proposed method under measurement noise.

description: This report is the third deliverable of WP4 “Technology Support” of the CLARITY project, funded by the EU’s
 Horizon 2020 Programme under Grant Agreement number 730355. WP4 provides the technological
 backbone of the CLARITY climate service Information System (CSIS) by tailoring the technological background
 to project needs. For this, WP4 will integrate and adapt existing (background) tools and services that are
 necessary for realisation of the CLARITY reference scenarios (demonstration cases) and the implementation
 of the EU-GL [1] into the CLARITY climate services.
 It is an accompanying report to the technologies and software components that are adapted, extended,
 customised and deployed by WP4 and configured, assembled and integrated by WP1 to implement the
 CLARITY CSIS. It reports on the work performed in WP4 since the project start, provides links to access the
 software, tools and documentation resulting from this work and summaries the continuously updated work
 plan that takes emerging requirements from the agile co-creation process and feedback from the end users
 of the CSIS and the demonstration cases into account

description: Cyber attacks constitute a significant threat to organizations with implications ranging from economic, reputational, and legal consequences. As cybercriminals' techniques get sophisticated, information security professionals face a more significant challenge to protecting information systems. In today's interconnected realm of computer systems, each attack vector has a network dimension. The present study investigates network intrusion attempts with anomaly-based machine learning models to provide better protection than the conventional misuse-based models. Two models, namely an ensemble learning model and a convolutional neural network model, were built and implemented on a data set gathered from a real-life, institutional production environment. To demonstrate the models' reliability and validity, they were applied to the UNSW-NB15 benchmarking data set. The type of attack was limited to probing attacks to keep the scope of the study manageable. The findings revealed high accuracy rates, the CNN model being slightly more accurate.

The nature of deformation-induced dislocations in SrTiO3: Insights from atomistic simulations

description: The nature of mechanically induced dislocations in SrTiO3 at low temperatures has been a disputed matter for a long time. Here we provide a systematic overview of the existing knowledge on dislocations in stoichiometric SrTiO3 complemented by computational models of several of the proposed dislocation types. Based on atomistic simulations we reveal their structure and mobility and put our focus on the splitting into partial dislocations, because this mechanism is held responsible for the good dislocation mobility in strontium titanate. Our results reveal that dislocations with a {1-10} glide plane (types A, B, and C) show easy glide behavior due to their glide dissociated configuration. The motion of dislocations on {001} glide planes (type E), however, is prohibited due to high Peierls barriers, as is the case for the {1-1-2} glide plane (type D). For dislocations with (partial) edge character the dissociation into partials is shown to be very sensitive to the charge state of the dislocation core. Since, in turn, dislocation mobility is strongly related to the dissociation of dislocations, the macroscopic ductility may in some cases have a direct relation to the charge at the dislocation core.

description: Explosive astrophysical transients at cosmological distances can be used to place precision tests of the basic assumptions of relativity theory, such as Lorentz invariance, the photon zero-mass hypothesis, and the weak equivalence principle (WEP). Signatures of Lorentz invariance violations (LIV) include vacuum dispersion and vacuum birefringence. Sensitive searches for LIV using astrophysical sources such as gamma-ray bursts, active galactic nuclei, and pulsars are discussed. The most direct consequence of a nonzero photon rest mass is a frequency dependence in the velocity of light propagating in vacuum. A detailed representation of how to obtain a combined severe limit on the photon mass using fast radio bursts at different redshifts through the dispersion method is presented. The accuracy of the WEP has been well tested based on the Shapiro time delay of astrophysical messengers traveling through a gravitational field. Some caveats of Shapiro delay tests are discussed. In this article, we review and update the status of astrophysical tests of fundamental physics.

An application of the dressed spin of 3He for a proposed neutron electric dipole moment measurement is also discussed.

description: Typical features of glass phenomenology such as the Vogel-Fulcher law, the Kauzmann paradox and the Adam-Gibbs relationship are shown to follow from the recently discovered mapping of glasses to Ising spin glasses in a magnetic field. There seems to be sufficient universality near the glass transition temperature $T_g$ such that study of the spin glass system can provide semi-quantitative results for supercooled liquids.

description: We consider two-component fermions on the lattice in the unitarity limit. This is an idealized limit of attractive fermions where the range of the interaction is zero and the scattering length is infinite. Using Euclidean time projection, we compute the ground state energy using four computationally different but physically identical auxiliary-field methods. The best performance is obtained using a bounded continuous auxiliary field and a non-local updating algorithm called hybrid Monte Carlo. With this method we calculate results for 10 and 14 fermions at lattice volumes 4^3, 5^3, 6^3, 7^3, 8^3 and extrapolate to the continuum limit. For 10 fermions in a periodic cube, the ground state energy is 0.292(12) times the ground state energy for non-interacting fermions. For 14 fermions the ratio is 0.329(5).

description: A newly developed sharp interface model describes crack propagation by a phase transition process. We solve this free boundary problem numerically and obtain steady state solutions with a self-consistently selected propagation velocity and shape of the crack, provided that elastodynamic effects are taken into account. Also, we find a saturation of the steady state crack velocity below the Rayleigh speed, tip blunting with increasing driving force and a tip splitting instability above a critical driving force.

description: We propose a simple and direct method for generating travelling wave solutions for nonlinear integrable equations. We illustrate how nontrivial solutions for the KdV, the mKdV and the Boussinesq equations can be obtained from simple solutions of linear equations. We describe how using this method, a soliton solution of the KdV equation can yield soliton solutions for the mKdV as well as the Boussinesq equations. Similarly, starting with cnoidal solutions of the KdV equation, we can obtain the corresponding solutions for the mKdV as well as the Boussinesq equations. Simple solutions of linear equations can also lead to cnoidal solutions of nonlinear systems. Finally, we propose and solve some new families of KdV equations and show how soliton solutions are also obtained for the higher order equations of the KdV hierarchy using this method.
