description: We explore the holographic duality between string theory in backgrounds that interpolate between asymptotically linear dilaton spacetime in the UV and $AdS_3$ in the IR, and single-trace $T\bar T$ deformed CFT. In particular, we explain how the deformation of states in the boundary theory is reflected in the bulk geometry, and show that the coupling above which the deformed energy of the $SL(2,\mathbb{R})$ invariant ground state of the IR CFT becomes complex is a maximal coupling.

description: Το χρηματοπιστωτικό σύστημα έχει υποστεί ραγδαίες αλλαγές την τελευταία δεκαετία με τις αλλαγές στο θεσμικό πλαίσιο στην Ευρώπη και την Ευρωζώνη. Η δυναμική του χρηματοπιστωτικού συστήματος επηρεάζεται από το εξελισσόμενο περιβάλλον και κατευθύνει την στρατηγική των χρηματοπιστωτικών συστημάτων. Στην παρούσα εργασία παρουσιάζονται οι χρηματοοικονομικοί δείκτες από τις τράπεζες της Ελλάδας για τα έτη 2004-2014, οι οποίοι συγκρίνονται με τους αντίστοιχους δείκτες τραπεζών της Ιταλίας και της Ισπανίας, περιφερειακών χωρών της Ευρωζώνης των οποίων η οικονομία υπέστη ανάλογη ύφεση με την Ελληνική. Συγκεκριμένα, κάθε χρηματοοικονομικός δείκτης αναλύεται ποιοτικά μέσω της επισκόπησης της διαχρονικής πορείας της μέσης τιμής του για το σύνολο των τραπεζών του δείγματος κάθε χώρας. Έπειτα, χρησιμοποιείται η πολυκριτήρια μέθοδος PROMETHEE II, για την αξιολόγηση των χρηματοοικονομικών επιδόσεων των τεσσάρων ελληνικών τραπεζών που που «επέζησαν» από την κρίση, των τριών ιταλικών και τριών ισπανικών για το χρονικό διάστημα 2005-2012.  Τέλος, πραγματοιποιείται μια επιπλέον εφαρμογή της πολυκριτήριας μεθόδου για τις ελληνικές τράπεζες πριν τις μαζικές συγχωνεύσεις, δηλαδή για τα έτη 2004-2010.

Origin of the heavy elements in HD 140283. Measurement of europium abundance

description: HD 140283 is a nearby (V=7.7) subgiant metal-poor star, extensively analysed in the literature. Although many spectra have been obtained for this star, none showed a signal-to-noise (S/N) ratio high enough to enable a very accurate derivation of abundances from weak lines. The detection of europium proves that the neutron-capture elements in this star originate in the r-process, and not in the s-process, as recently claimed in the literature. Based on the OSMARCS 1D LTE atmospheric model and with a consistent approach based on the spectrum synthesis code Turbospectrum, we measured the europium lines at 4129 Å and 4205 Å, taking into account the hyperfine structure of the transitions. The spectrum, obtained with a long exposure time of seven hours at the Canada-France-Hawaii Telescope (CFHT), has a resolving power of 81000 and a S/N ratio of 800 at 4100 Å. We were able to determine the abundance A(Eu)=-2.35 dex, compatible with the value predicted for the europium from the r-process. The abundance ratio [Eu/Ba]=+0.58 dex agrees with the trend observed in metal-poor stars and is also compatible with a strong r-process contribution to the origin of the neutron-capture elements in HD 140283.

Scale dependence of the q and T parameters of the Tsallis distribution in the process of jet fragmentation

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The dependence of the $q$ and $T$ parameters of the Tsallis-distribution-shaped fragmentation function (FF) on the fragmentation scale (found to be equal to the jet mass) is calculated via the resummation of the branching process of jet fragmentation in the leading-log appriximation (LLA) in the $ϕ^3$ theory. Jet and hadron spectra in electron-positron ($e^+e^-$) annihilations with 2- and 3-jet final states are calculated using virtual leading partons. It is found that jets, produced earlier in the branching process, are more energetic, and the energy, angle and multiplicity distributions of hadrons stemming from them are broader. It is also found that replacing the LL resummation in the branching process by a single splitting provides good approximation for the jet energy distribution in 2-jet events. Furthermore, a micro-canonical statistical event generator is presented for the event-by-event calculation of hadron momenta in $e^+e^-$ annihilations.

description: We present a determination of the b-quark mass accurate through O(α_s^2) in perturbation theory and including partial contributions at O(α_s^3). Nonperturbative input comes from the calculation of the Upsilon and B_s energies in lattice QCD including the effect of u, d and s sea quarks. We use an improved NRQCD action for the b-quark. This is combined with the heavy quark energy shift in NRQCD determined using a mixed approach of high-beta simulation and automated lattice perturbation theory. Comparison with experiment enables the quark mass to be extracted: in the MS bar scheme we find m_b(m_b) = 4.166(43) GeV.

Learning unidirectional coupling using echo-state network

Year: 2023
Subjects: subject: Machine Learning (cs.LG)
subject: FOS: Computer and information sciences

description: Reservoir Computing has found many potential applications in the field of complex dynamics. In this article, we exploit the exceptional capability of the echo-state network (ESN) model to make it learn a unidirectional coupling scheme from only a few time series data of the system. We show that, once trained with a few example dynamics of a drive-response system, the machine is able to predict the response system's dynamics for any driver signal with the same coupling. Only a few time series data of an $A-B$ type drive-response system in training is sufficient for the ESN to learn the coupling scheme. After training even if we replace drive system $A$ with a different system $C$, the ESN can reproduce the dynamics of response system $B$ using the dynamics of new drive system $C$ only.
Enhancement of valley selective excitation by a linearly polarized two-color laser pulse

description: Here we proposed the valley selective excitations via a two-color (\ensuremathω + \ensuremath{2ω}) laser field, made by superimposing two linearly polarized pulses at frequencies \ensuremathω and \ensuremath{2ω}. We have studied the intensity ratio between a few-cycle pulse of \ensuremathω and \ensuremath{2ω} laser, and its enhancement factor by employing the time-dependent first-principle calculations. The valley polarization depends on the carrier envelope phases (CEPs) of pulses and the intensity ratio $I_ω/I_{2ω}$. We found that the two-color field enhances the valley polarization as much as 1.2 times larger than the single-color pulse. The maximum valley asymmetry is achieved for the intensity ratio $I_ω/I_{2ω}$ of 36 with the relative CEP of \ensuremathπ. In our previous work, we found that the asymmetric vector potential induces the valley polarization (Phys. Rev. B 105,115403 (2022)). In this work, we find that the asymmetry of the electric field modulates the valley polarization. Our two-color scheme offers a new path toward the optical control of valley pseudospins. \end{abstract}

description: Using the RAVE survey, we recently brought to light a gradient in the mean galactocentric radial velocity of stars in the extended solar neighbourhood. This gradient likely originates from non-axisymmetric perturbations of the potential, among which a perturbation by spiral arms is a possible explanation. Here, we apply the traditional density wave theory and analytically model the radial component of the two-dimensional velocity field. Provided that the radial velocity gradient is caused by relatively long-lived spiral arms that can affect stars substantially above the plane, this analytic model provides new independent estimates for the parameters of the Milky Way spiral structure. Our analysis favours a two-armed perturbation with the Sun close to the inner ultra-harmonic 4:1 resonance, with a pattern speed Ω_p=18.6^{+0.3}_{-0.2} km/s/kpc and a small amplitude A=0.55 \pm 0.02% of the background potential (14% of the background density). This model can serve as a basis for numerical simulations in three dimensions, additionally including a possible influence of the galactic bar and/or other non-axisymmetric modes.

description: We compute the spectra of flux tubes formed between a static quark antiquark pair up to a significant number of excitations and for eight symmetries of the flux tubes, up to $Δ_u$, using pure $SU(3)$ gauge lattice QCD in 3+1 dimensions. To accomplish this goal, we use a large set of appropriate operators, an anisotropic tadpole improved action, smearing techniques, and solve a generalized eigenvalue problem. Moreover, we compare our results with the Nambu-Goto string model to evaluate possible tensions which could be a signal for novel phenomena. Especially, we provide evidence for the coupling of a massive particle, say an axion, to the $Σ_g^-$, $Σ_u^-$, and $Σ_u^{-*}$ flux tube with approximate masses $ 2.25\sqrtσ$, $1.85\sqrtσ$, $3.30\sqrtσ$, respectively.

The branching fraction of the axino decay into monochromatic photons can be O(1), and constraints from continuum gamma-rays and the anti-proton flux are ameliorated. The Peccei-Quinn scale of $O(10^{13}-10^{14})$\,GeV and the R-parity violation parameter of $O(10^{-12}-10^{-11})$ are cosmologically favored.

description: We have set up a diagnostic magnet (D-Mag) laboratory for a wide range of applications in plasma physics. It consists of a superconducting magnet for field strengths of up to 5.9 T. The main purpose is to provide an experimental environment for the development of plasma diagnostics for nuclear fusion studies and the investigation of dusty plasmas in strong magnetic fields. We describe in the article the setup and operation of the D-Mag. Some applications are presented for the development of plasma diagnostics, such as neutral pressure gauges and Langmuir probes that have to be operated in strong magnetic fields. Among the examples is the test of the long-pulse capability and stability of the diagnostic pressure gauge (DPG) for the ITER device.

description: We present HST/STIS time-series spectroscopy of the central star of the "Cat's Eye" planetary nebula NGC 6543. Intensive monitoring of the UV lines over a 5.8 hour period reveals well defined details of large-scale structure in the fast wind, which are exploited to provide new constraints on the rotation rate of the central star. We derive characteristics of the line profile variability that support a physical origin due to co-rotating interaction regions (CIRs) that are rooted at the stellar surface. The recurrence time of the observed spectral signatures of the CIRs is used to estimate the rotation period of the central star and, adopting a radius between 0.3 and 0.6 \Rsun constrains the rotational velocity to the range 54 \leq v_{rot} \leq 108 \kms. The implications of these results for single star evolution are discussed based on models calculated here for low-mass stars. Our models predict a sub-surface convective layer in NGC 6543 which we argue to be causally connected to the occurrence of structure in the fast wind.

description: Electron pumps capable of delivering a current higher than 100pA with sufficient accuracy are likely to become the direct mise en pratique of the possible new quantum definition of the ampere. Furthermore, they are essential for closing the quantum metrological triangle experiment which tests for possible corrections to the quantum relations linking e and h, the electron charge and the Planck constant, to voltage, resistance and current. We present here single-island hybrid metal/semiconductor transistor pumps which combine the simplicity and efficiency of Coulomb blockade in metals with the unsurpassed performances of silicon switches. Robust and simple pumping at 650MHz and 0.5K is demonstrated. The pumped current obtained over a voltage bias range of 1.4mV corresponds to a relative deviation of 5e-4 from the calculated value, well within the 1.5e-3 uncertainty of the measurement setup. Multi-charge pumping can be performed. The simple design fully integrated in an industrial CMOS process makes it an ideal candidate for national measurement institutes to realize and share a future quantum ampere.

description: Introductory undergraduate courses in classical physics stress a perspective that can be characterized as realist; from this perspective, all physical properties of a classical system can be simultaneously specified and thus determined at all future times. Such a perspective can be problematic for introductory quantum physics students, who must develop new perspectives in order to properly interpret what it means to have knowledge of quantum systems. We document this evolution in student thinking in part through pre- and post-instruction evaluations using the Colorado Learning Attitudes about Science Survey. We further characterize variations in student epistemic and ontological commitments by examining responses to two essay questions, coupled with responses to supplemental quantum attitude statements. We find that, after instruction in modern physics, many students are still exhibiting a realist perspective in contexts where a quantum-mechanical perspective is needed. We further find that this effect can be significantly influenced by instruction, where we observe variations for courses with differing learning goals. We also note that students generally do not employ either a realist or a quantum perspective in a consistent manner.

description: The paper considers the evolution of the supernova envelopes produced by Population III stars with masses of $M_*\sim 25-200 M_\odot$ located in non-rotating protogalaxies with masses of $M\sim 10^7 M_\odot$ at redshifts $z=12$, with dark-matter density profiles in the form of modified isothermal spheres. The supernova explosion occurs in the ionization zone formed by a single parent star. The properties of the distribution of heavy elements (metals) produced by the parent star are investigated, as well as the efficiency with which they are mixed with the primordial gas in the supernova envelope. In supernovae with high energies ($E\simgt 5\times 10^{52}$ erg), an appreciable fraction of the gas can be ejected from the protogalaxy, but nearly all the heavy elements remain in the protogalaxy. In explosions with lower energies ($E\simlt 3\times 10^{52}$ erg), essentially no gas and heavy elements are lost from the protogalaxy: during the first one to threemillion years, the gas and heavy elements are actively carried from the central region of the protogalaxy ($r\sim 0.1 r_{vir}$, where $r_{vir}$ is the virial radius of the protogalaxy), but an appreciable fraction of the mass of metals subsequently returns when the hot cavity cools and the envelope collapses. Supernovae with high energies ($E\simgt 5\times 10^{52}$ erg) are characterized by a very low efficiency of mixing of metals; their heavy elements are located in the small volume occupied by the disrupted envelope (in a volume comparable with that of the entire envelope), with most of the metals remaining inside the hot, rarified cavity of the envelope.

description: In order to try and understand its origins, we present high-quality long-slit spectral observations of the counter-rotating stellar discs in the strange S0 galaxy NGC 4550. We kinematically decompose the spectra into two counter-rotating stellar components (plus a gaseous component), in order to study both their kinematics and their populations. The derived kinematics largely confirm what was known previously about the stellar discs, but trace them to larger radii with smaller errors; the fitted gaseous component allows us to trace the hydrogen emission lines for the first time, which are found to follow the same rather strange kinematics previously seen in the [OIII] line. Analysis of the populations of the two separate stellar components shows that the secondary disc has a significantly younger mean age than the primary disc, consistent with later star formation from the associated gaseous material. In addition, the secondary disc is somewhat brighter, also consistent with such additional star formation. However, these measurements cannot be self-consistently modelled by a scenario in which extra stars have been added to initially-identical counter-rotating stellar discs, which rules out Evans & Collett's (1994) elegant "separatrix-crossing" model for the formation of such massive counter-rotating discs from a single galaxy, leaving some form of unusual gas accretion history as the most likely formation mechanism.

description: Spirals in multiphoton pair production are revisited by two counter-rotating fields with time delay for different cycles in pulse. Novel findings include that for subcycle fields, the remarkable spiral structure in the momentum spectrum can be still caused by a large time delay compared to the previous study for supercycle case where it is easier to be generated by a small time delay. And also there exist a range of critical polarization values for the spirals appearance corresponding to the different cycle number. The relative phase difference between two fields causes not only severe symmetry breaking of the momentum spectra pattern and spiral, but also a significant change for the shape and the number of spiral arm. Upon the number density, it is found a more sensitive to the cycle number, in particularly, it is enhanced by more than one order of magnitude for small cycle pulse, while it is increased about few times when the time delay is small. These results provide an abundant theoretical testbed for the possible experimental observation on the multiphoton pair production in future. Meanwhile, it is applicable to regard the particles momentum signatures as a new probing to the laser field information with it from the vacuum.

description: Recent studies have shown that pseudo labels can contribute to unsupervised domain adaptation (UDA) for speaker verification. Inspired by the self-training strategies that use an existing classifier to label the unlabeled data for retraining, we propose a cluster-guided UDA framework that labels the target domain data by clustering and combines the labeled source domain data and pseudo-labeled target domain data to train a speaker embedding network. To improve the cluster quality, we train a speaker embedding network dedicated for clustering by minimizing the contrastive center loss. The goal is to reduce the distance between an embedding and its assigned cluster center while enlarging the distance between the embedding and the other cluster centers. Using VoxCeleb2 as the source domain and CN-Celeb1 as the target domain, we demonstrate that the proposed method can achieve an equal error rate (EER) of 8.10% on the CN-Celeb1 evaluation set without using any labels from the target domain. This result outperforms the supervised baseline by 39.6% and is the state-of-the-art UDA performance on this corpus.

description: The financial crisis that struck Greece in 2009 strongly affected the Greek economy and by extension the entrepreneurship. This research is focused on examining the way in which the economic crisis has affected the Greek entrepreneurship and to investigate the factors which can make a business sustainable or even profitable during a recession. The sample consists of 20 profitable businesses of all kinds of sectors apart from the banking/insurance sector and the time period of interest is 2009 to 2013. The research begins with theoretical reviews and bibliographic references and then it is followed by a financial analysis that uses financial indicators. Then, the most important elements are evaluated with the use of a factor analysis to be used in a multicriteria decision aid tool, the PROMETHEE outranking method, that contributes to the classification of the enterprises. The results of this report have proven the original idea of the research, that recession doesn’t only depress but it also creates opportunities.

description: Recent studies have implied that environmental toxins, such as mycotoxins, are risk factors for neurodegenerative diseases. To act directly as neurotoxins, mycotoxins need to penetrate or affect the integrity of the blood-brain barrier, which protects the mammalian brain from potentially harmful substances. As common food and feed contaminants of fungal origin, the interest in the potential neurotoxicity of ochratoxin A, citrinin and their metabolites has recently increased. Primary porcine brain capillary endothelial cells were used to investigate cytotoxic or barrier-weakening effects of ochratoxin A, ochratoxin α, citrinin and dihydrocitrinone. The transfer and transport properties of the mycotoxins across the barrier formed by porcine brain capillary endothelial cell monolayers were analysed using HPLC-MS/MS. High levels of Ochratoxin A caused cytotoxic and barrier-weakening effects, whereas ochratoxin α, citrinin and dihydrocitrinone showed no adverse effects up to 10 µM. Likely due to efflux transporter proteins, the transfer to the brain compartment was much slower than expected from their high lipophilicity. Due to their slow transfer across the blood-brain barrier, cerebral exposure of ochratoxin A, ochratoxin α, citrinin and dihydrocitrinone is low and neurotoxicity is likely to play a subordinate role in their toxicity at common physiological concentrations.

description: Abstract
Serverless Cloud computing expanding its domain rapidly. This is simple, efficient, light-weight, secure and ubiquitous. All Cloud players provide it with different attractive names such as Amazone branding it with AWS Lambda, Goole using Cloud Run, Ali Baba calling it Function Compute and last but not least Microsoft providing serverless cloud with name of Azure Function. Normally, function service executes the core business logic of application and host's machine policy of execution create a significant impact of overall quality of service provided by CSP (Cloud Service Provider). To produce an effective execution policy, the host machine maintains a lean balance between Cold and Hot restart. Policy efforts to reduce Cold restart but manage resources during Hot restart. In this paper, we employed a machine learning based classification methodology that segregate the functions in terms of cold and hot functions. We implemented Naïve Bayes classifier and boosting the accuracy with Kernel Density Estimation. The overall best accuracy was observed up to 94.35%.

description: Στην παρούσα διπλωματική εργασία με θέμα «Επιθεωρήσεις Ασφάλειας στην οδική μεταφορά επικίνδυνων υλικών», παρουσιάζεται αρχικά η ισχύουσα νομοθεσία που αφορά στην ασφάλεια στο οδικό δίκτυο και οι νομοθετικές απαιτήσεις των αναγνωρισμένων ομάδων - στόχων του προγράμματος. Στη συνέχεια παρατίθεται το υπάρχον σύστημα καθ’οδόν ελέγχων στην Ελλάδα καθώς και από ποιους πραγματοποιούνται οι έλεγχοι αυτοί. Γίνεται διερεύνηση των προβλημάτων που προκύπτουν από τους ανεπαρκείς και λιγοστούς καθ’οδόν ελέγχους και παρουσιάζονται προτάσεις για βελτίωση. Παρατίθεται και αναλύεται η καινοτόμος ιδέα ενός ηλεκτρονικού εργαλείου ελέγχων οχημάτων κατά τη μεταφορά επικίνδυνων εμπορευμάτων ADR, το οποίο θα μπορέσει να δώσει άλλη διάσταση στους ελέγχους αυτούς, καθιστώντας τους ταχύτερους και πληρέστερους. Τέλος, έχοντας έρθει σε επαφή με το Υπουργείο Μεταφορών της Γερμανίας μέσω του γερμανικού Προξενείου στα Χανιά, αποτυπώνεται το αποτέλεσμα της επικοινωνίας, που ως στόχο είχε την αναζήτηση ύπαρξης ενός αντίστοιχου ηλεκτρονικού εργαλείου. Πώς εκείνο λειτουργεί και από ποιους χρησιμοποιείται. Τα αποτελέσματα της έρευνας μπορούν να φανούν χρήσιμα στην καθημερινή ζωή, τόσο στους απλούς πολίτες όσο και στο έργο των οργάνων του Υπουργείου Υποδομών, Μεταφορών και Δικτύων που διενεργούν οδικούς ελέγχους για την εφαρμογή της Ευρωπαικής Συμφωνίας ADR.
description: This thesis on "Safety Inspections in the carriage of dangerous goods", originally presented the current legislations regarding the safety of the road network and the legislative requirements of recognized groups - program objectives. Then, given the existing system at roadside checks in Greece and by whom these checks are made. It investigates the problems arising from the inadequate and scarce roadside checks and presents proposals for improvement. Then, set out and discussed the innovative idea of an electronic vehicle control tool during the transport of dangerous goods ADR, which can give another dimension to those controls, making them faster and more comprehensive. Finally, having come into contact with the Ministry of Transport of Germany through the German Embassy in Chania, reflect the result of communication with the German state, in the context of the search for a corresponding electronic tool. The results of the survey may be useful in everyday life, both for citizens as well as the work of the Ministry of Infrastructure, Transport and Networks carrying out roadside checks on the implementation of the ADR.

description: Lithium-rich giant stars are rare and their existence challenges our understanding of stellar structure and evolution. We profit from the high-quality sample gathered with HARPS and UVES, in order to search for Li-rich giants and to identify the Li enrichment mechanisms responsible. We derive stellar parameters for 247 stars belonging to 32 open clusters, with 0.07 Ga < ages < 3.6 Ga. We employed the spectral synthesis technique code FASMA for the abundance analysis of 228 stars from our sample. We also determined ages, distances, and extinction using astrometry and photometry from Gaia and PARSEC isochrones to constrain their evolutionary stage. Our sample covers a wide range of stellar masses from 1 to more than 6 solar masses where the majority of the masses are above 2 solar masses. We have found 14 canonical Li-rich giant stars which have experienced the first dredge-up. This corresponds to 6% of our total sample, which is higher than what is typically found for field stars. Apart from the canonical limit, we use the maximum Li abundance of the progenitor stars as a criterion for Li enrichment. We find Li enhancement also among eight stars which have passed the first dredge up and show strong Li lines based on the fact that stars at the same evolutionary stage in the same cluster have significantly different Li abundances. We confirm that giants with higher Li abundance correspond to a higher fraction of fast-rotating giants, suggesting a connection between Li enhancement and stellar rotation as predicted by stellar models. Our Li-rich giants are found in various evolutionary stages implying that no unique Li production mechanism is responsible for Li enrichment but rather different intrinsic or external mechanisms can be simultaneously at play.
