description: Η σύμβαση πιστωτικής κάρτας του τριμερούς συστήματος έχει τρία διακριτά μέρη και αποτελείται τοιουτοτρόπως από τρεις διακριτές σχέσεις: την σχέση μεταξύ κατόχου και εκδότη πιστωτικής κάρτας, ο οποίος είναι πιστωτικό ίδρυμα, την σχέση μεταξύ του εκδότη πιστωτικής κάρτας και της συμβεβλημένης με αυτόν επιχείρησης και την σχέση του κατόχου της πιστωτικής κάρτας και της συμβεβλημένης με τον εκδότη επιχείρησης. Η παρούσα εργασία ασχολείται με την ανάλυση των σχέσεων αυτών και ειδικότερα με τη σύναψη των συμβάσεων μεταξύ των μερών, τη νομική τους φύση, τις υποχρεώσεις των μερών που προκύπτουν από αυτές, την παθολογική εξέλιξη των σχέσεων και τη λύση αυτών. Τέλος, ερευνάται το ερώτημα κατά πόσο η ανατροπή της σύμβασης του κατόχου και της συμβεβλημένης με τον εκδότη επιχείρησης μπορεί να αποτελέσει λόγο ανώμαλης εξέλιξης της σύμβασης μεταξύ εκδότη και κατόχου.
description: The contract of credit card in a tripartite system consists of three different contracting parties and thereby of three distinctive relations: the relation between the possessor and the editor of the credit card who is usually a bank, the relation between the editor of the credit card and the enterprise which has entered into an agreement with the editor and the relation between the possessor of the credit card and the enterprise which has concluded a contract with the editor. The present essay deals with the analysis of these relations and specifically with the joining of the contracts by the different parties, the legal nature of the contracts, the contractual obligations of the parties, the pathologic evolution of the relations and the legal end of them. Finally, the author tries to explain to what an extent the breach of the contractual terms between the possessor of the credit card and the enterprise which has entered into an agreement with the editor can affect the regular evolution of the contract between the possessor and the editor of the credit card.

description: In this thesis we deal with image processing, focusing on the image inpainting (or completion) problem. We define the problem and prescribe the key requirements and analyze the best algorithms that have been implemented so far. In order to deal with problems arising with heuristic algorithms implementations, we introduce Markov Random Fields Theory and consider the image completion as a discrete optimization problem. We compare and evaluate the proposed algorithms as well as we present selected of the algorithms outputs. We underline conclusions useful in practice. Finally, we present the recently developed Hays‐Efros algorithm based on semantic processing in which the completion of the “missing area” is implemented by searching contextually for nearest neighbours in an image database of millions of photographs.

description: Artificial intelligence (AI) offers a transformative approach to education, providing personalized, engaging, and efficient learning experiences. Utilizing machine learning and natural language processing, AI aids in customizing education by analyzing data, recognizing patterns, and making predictions. This leads to benefits like personalized learning, allowing students to learn at their own pace, and tools like intelligent tutoring systems and automated grading, which save educators' time.

However, integrating AI into education also presents challenges, including privacy and security concerns, trust issues, financial limitations, and potential biases in AI systems. Ethical considerations such as accessibility, transparency, and fairness are crucial. Despite these challenges, the advantages of AI in education, particularly in data-driven decision-making, are significant. This review discusses AI's role in improving and managing education, examining its impact and recent literature.

Synthesis, Structure, and Ferromagnetism of a New Oxygen Defect Pyrochlore System Lu2V2O_{7-x} (x = 0.40-0.65)

description: A new fcc oxygen defect pyrochlore structure system Lu2V2O_{7-x} with x = 0.40 to 0.65 was synthesized from the known fcc ferromagnetic semiconductor pyrochlore compound Lu2V2O7 which can be written as Lu2V2O6O' with two inequivalent oxygen sites O and O'. Rietveld x-ray diffraction refinements showed significant Lu-V antisite disorder for x >= 0.5. The lattice parameter versus x (including x = 0) shows a distinct maximum at x ~ 0.4. We propose that these observations can be explained if the oxygen defects are on the O' sublattice of the structure. The magnetic susceptibility versus temperature exhibits Curie-Weiss behavior above 150 K for all x, with a Curie constant C that increases with x as expected in an ionic model. However, the magnetization measurements also show that the (ferromagnetic) Weiss temperature theta and the ferromagnetic ordering temperature T_C both strongly decrease with increasing x instead of increasing as expected from C(x). The T_C decreases from 73 K for x = 0 to 21 K for x = 0.65. Furthermore, the saturation moment at a field of 5.5 T at 5 K is nearly independent of x, with the value expected for a fixed spin 1/2 per V. The latter three observations suggest that Lu2V2O_{7-x} may contain localized spin 1/2 vanadium moments in a metallic background that is induced by oxygen defect doping, instead of being a semiconductor as suggested by the C(x) dependence.

Synthesis and characterization of cationic latex bearing grafted chains
Creators: name: Hritcu, Doina
Publisher: name: University of British Columbia
Year: 2009

description: Cationic poly(styrene) latices bearing grafted chains were synthesized by surface initiated polymerization of N(2-methoxy-ethyl) acrylamide (MEA) on core latex. The 2-3 |j.m diameter core particles were produced by successive seeded growth polymerization using a cationic azo-derivative as initiator. The area per charged group was found by conductometric titration to be between 150 and 300 A². The core latex was covered with a shell containing poly(styrene-co-acrolein) by a seeded copolymerization procedure. The surface aldehyde concentration was determined by reaction with hydroxylamine hydrochloride and titration. The surface aldehyde groups were used as starting points for Ce(IV) redox initiated polymerization of MEA. The amount of grafted MEA was estimated indirectly from unreacted monomer concentration. The maximum tether coverage, 9.9 MEA groups/A², was obtained for an aldehyde surface concentration of 2.8 groups/A². The probable chain conformation is a dense brush with an equilibrium length from 20 to 133 A. A model latex carrying cleavable chains was synthesized by using a shell containing poly(styrene-co-hydroxy-ethyl acrylate). The procedure for producing the shell and for grafting M E A was the same as for the aldehyde latex. The density of surface hydroxyl groups was assessed by saponification of the ester bonds, followed by conductometric titration of the carboxylic residues. In all experiments competing solution polymerization of M E A occurred due to oligomer leakage from the bead. The grafted chains were characterized by quantitative size exclusion chromatography (SEC) after saponification. The molecular weight showed an unusual trimodal distribution. The surface density of the long chains was found to be between 4.4xl0⁻⁵ and 1.3xl0⁻⁴ chains/A². Short and oligomeric chains had a density of about 6xl0⁻⁴ chains/A². The probable configuration of each of these species is a mushroom, extending into solution to a maximum of 50 A. The beads carrying grafted chains were used as stationary phases for SEC of proteins. Experimental evidence for graft-mediated size exclusion, as predicted by two theoretical models, was provided, demonstrating that SEC can be performed efficiently with nonporous media.

description: In this paper we present the thermal and mechanical analysis of high-power light-emitting diodes (LEDs) with ceramic packages. Transient thermal measurements and thermo-mechanical simulation were performed to study the thermal and mechanical characteristics of ceramic packages. Thermal resistance from the junction to the ambient was decreased from 76.1 oC/W to 45.3 oC/W by replacing plastic mould to ceramic mould for LED packages. Higher level of thermo-mechanical stresses in the chip were found for LEDs with ceramic packages despite of less mismatching coefficients of thermal expansion comparing with plastic packages. The results suggest that the thermal performance of LEDs can be improved by using ceramic packages, but the mounting process of the high power LEDs with ceramic packages is critically important and should be in charge of delaminating interface layers in the packages.

Ειδικότερα, τα προβλήματα των Galileo Galilei και Fermat, αλλά και τα προβλήματα ελαχιστοποίησης αντίστασης του μεταγενέστερου Newton. αφορούσαν ένα εντελώς νέο έως τότε πεδίο, και οι τεχνικές που αναπτύχθηκαν βοήθησαν αργότερα τον Johann Bernoulli να διατυπώσει αλλά και να επιλύσει το βραχυστόχρονο πρόβλημα.

Συγκεκριμένα, οι Euler και Lagrange, αφού μελέτησαν το βραχυστόχρονο, εισήγαγαν μεθόδους ανάλυσης που αποτέλεσαν ορόσημο στη δημιουργία του λογισμού Μεταβολών.
description: The present paper addresses the contribution of the resolution of the Brachystochrone problem to the origin of the calculus of variations. The paper presents the beginning of the Brachystochrone problem, which has its roots back in ancient times, as well as the historical context of the later mathematicians. In particular, a number of problems from Galileo Galilei and Fermat, along with Newton’s problem of minimizing resistance of bodies constituted an entirely new field of mathematics for that time, and the techniques developed helped Johann Bernoulli later to define and solve the Brachystochrone problem. Furthermore, the Brachystochrone problem is defined and its solution based on Johann Bernoulli is developed. A more systematic approach to solving such problems is shown, as by then the approach involved mainly geometrical methods. In particular, Euler and Lagrange, having studied the Brachystochrone, introduced analytical methods that were a landmark in creating the calculus of variations.

description: The guiding centre dynamics of fast particles can alter the behaviour of energetic particle driven modes with chirping frequencies. In this paper, the applicability of an earlier trapped/passing locus model [H. Hezaveh et al 2017 Nucl. Fusion 57 126010] has been extended to regimes where the wave trapping region can expand and trap ambient particles. This extension allows the study of waves with up-ward and down-ward frequency chirping across the full range of energetic particle orbits. Under the adiabatic approximation, the phase-space of energetic particles is analysed by a Lagrangian contour approach where the islands are discretised using phase-space waterbags. In order to resolve the dynamics during the fast formation of phase-space islands and find an appropriate initialisation for the system, full-scale modelling is implemented using the bump-on-tail (BOT) code. In addition to investigating the evolution of chirping waves with deepening potentials in a single resonance, we choose specific pitch-angle ranges in which higher resonances can have a relatively considerable contribution to the wave-particle interaction. Hence, the model is also solved in a double-resonance scenario where we report on the significant modifications to the behaviour of the chirping waves due to the $2^{\text{nd}}$ resonance. The model presented in this paper gives a comprehensive 1D paradigm of long range frequency chirping signals observed in experiments with both up-ward and down-ward chirping and multiple resonances.

description: The effect of variations of the fundamental nuclear parameters on big-bang nucleosynthesis are modeled and discussed in detail taking into account the interrelations between the fundamental parameters arising in unified theories. Considering only \he4, strong constraints on the variation of the neutron lifetime, neutron-proton mass difference are set. These constraints are then translated into constraints on the time variation of the Yukawa couplings and the fine structure constant. Furthermore, we show that a variation of the deuterium binding energy is able to reconcile the \li7 abundance deduced from the WMAP analysis with its spectroscopically determined value while maintaining concordance with D and \he4. The analysis is strongly based on the potential model of Flambaum and Shuryak that relates the binding energy of the deuteron with the nucleon and $σ$ and $ω$ mesons masses, however, we show that an alternative approach that consists of a pion mass dependence necessarily leads to equivalent conclusions.

Dynamic complexation of solutes in capillary electrophoresis
Creators: name: Bowser, Michael T.
Publisher: name: University of British Columbia
Year: 2009

description: A general theory that describes analyte migration behavior in chromatography, electrophoresis, and ultracentrifugation is described. The theory accounts for multiple stoichiometry and multiple additive interactions through the use of individual capacity factors. The unified separation theory includes a general expression for resolution which shows that the resolution of a pair of analytes is linearly related to the ratio of the linear velocities of the two analytes. A CE separation with the presence of both 1:1 and 1:2 stoichiometry analyte-additive interactions is described using the general separation theory. The effect of the higher order interactions on the mobility of the analyte and methods for detecting deviations from the 1:1 model are discussed. Multivariate binding isotherms are used to describe the effect of multiple equilibria on analyte mobility. The effect of secondary interactions on the shapes of these curves is determined. The general theory is especially useful in describing hybrid techniques such as capillary electrochromatography. The statistical methods for estimating equilibrium constants from binding experiments are compared using Monte Carlo analyses. Simulated experiments with realistic error assumptions are used to compare the accuracy and precision of the nonlinear regression to the three linear plotting methods. The effect of the additive concentration range and the maximum response range was demonstrated. It was shown that binding constants estimated using nonlinear regression were generally more accurate and more precise than constants estimated using one of the linear transformations. The effect of experimental conditions on the precision of the binding constant estimates was shown to be related to the curvature in the binding isotherm. The solvent can have an important effect on analyte-additive interactions in CE. An assay for an oligomeric porphyrin anti-cancer drug was used as an example of nonaqueous CE separations. It was shown that the dipolar interaction between the porphyrins and a nonionic polyether surfactant (brij 35) could be used to improve separation selectivity. A group of monomeric porphyrin acids was studied to gain insight into the mechanism of the brij 35- porphyrin interaction in nonaqueous buffers. It was proposed that brij 35 interacts with the carboxyl groups on the porphyrins through dipolar interactions. It was also suggested that the orientation of porphyrin acids in the electric field might have an effect on their mobilities.

description: There are many processes that can transport gas from the galaxies to their environment and enrich the environment in this way with metals. These metal enrichment processes have a large influence on the evolution of both the galaxies and their environment. Various processes can contribute to the gas transfer: ram-pressure stripping, galactic winds, AGN outflows, galaxy-galaxy interactions and others. We review their observational evidence, corresponding simulations, their efficiencies, and their time scales as far as they are known to date. It seems that all processes can contribute to the enrichment. There is not a single process that always dominates the enrichment, because the efficiencies of the processes vary strongly with galaxy and environmental properties.

description: This paper develops a two-part finite mixture quantile regression model for semi-continuous longitudinal data. The proposed methodology allows heterogeneity sources that influence the model for the binary response variable, to influence also the distribution of the positive outcomes. As is common in the quantile regression literature, estimation and inference on the model parameters are based on the Asymmetric Laplace distribution. Maximum likelihood estimates are obtained through the EM algorithm without parametric assumptions on the random effects distribution. In addition, a penalized version of the EM algorithm is presented to tackle the problem of variable selection. The proposed statistical method is applied to the well-known RAND Health Insurance Experiment dataset which gives further insights on its empirical behavior.

description: The study of the metal enrichment of the intra-cluster and inter-galactic media (ICM and IGM) represents a direct means to reconstruct the past history of star formation, the role of feedback processes and the gas-dynamical processes which determine the evolution of the cosmic baryons. In this paper we review the approaches that have been followed so far to model the enrichment of the ICM in a cosmological context. While our presentation will be focused on the role played by hydrodynamical simulations, we will also discuss other approaches based on semi-analytical models of galaxy formation, also critically discussing pros and cons of the different methods. We will first review the concept of the model of chemical evolution to be implemented in any chemo-dynamical description. We will emphasise how the predictions of this model critically depend on the choice of the stellar initial mass function, on the stellar life-times and on the stellar yields. We will then overview the comparisons presented so far between X-ray observations of the ICM enrichment and model predictions. We will show how the most recent chemo-dynamical models are able to capture the basic features of the observed metal content of the ICM and its evolution. We will conclude by highlighting the open questions in this study and the direction of improvements for cosmological chemo-dynamical models of the next generation.

description: Interferometers with kilometer-scale arms have been built for gravitational-wave detections on the ground; ones with much longer arms are being planned for space-based detection. One fundamental motivation for long baseline interferometry is from displacement noise. In general, the longer the arm length L, the larger the motion the gravitational-wave induces on the test masses, until L becomes comparable to the gravitational wavelength. Recently, schemes have been invented, in which displacement noises can be evaded by employing differences between the influence of test-mass motions and that of gravitational waves on light propagation. However, in these schemes, such differences only becomes significant when L approaches the gravitational wavelength, and shot-noise limited sensitivity becomes worse than that of conventional configurations by a factor of at least (f L/c)^(-2), for f

description: The Mid-infrared E-ELT Thermal Infrared imager and Spectrograph (METIS) is one of the three first-light instruments selected for the European Extremely Large Telescope (ELT) and will cover the thermal infrared wavelength range, from ca. 3 - 13 microns. It will be a versatile instrument featuring diffraction-limited imaging and long-slit spectroscopy in the L/M and N bands as well as high spectral resolution (R ~ 100,000) integral field spectroscopy in the L and M bands. Its spatial resolution of 25 (70) mas in the L (N) band corresponds to a linear scale of 1 (3) parsec in nearby (10 Mpc) galaxies. For nearby AGNs, METIS forms the missing link between JWST and ground-based interferometry in both resolution and sensitivity. METIS will primarily observe continuum emission from dust at 100-800 K, but it will also be sensitive to the emission lines in this wavelength range, e.g. Brackett alpha, coronal lines like [SiIX] and [ArVI] and [AlVI], molecular lines of CO and H2O, and broad silicate emission and absorption lines. As such it is well matched to tackle several of the outstanding questions in current AGN research including "What triggers AGN activity?" and "How do AGN outflows connect to the host galaxy?". In this talk, I review METIS' instrumental capabilities with a particular focus on the prospects for AGN research.

The cluster hosts one of the largest giant radio halos which are observed in most of the merging clusters, and a candidate radio relic. Recently, three merger shock fronts were detected in this cluster, explaining its extreme temperature and complex structure. Furthermore, previous XMM-Newton and Chandra observations hinted at the presence of a shock front that is associated with the gas `bullet' crossing the main cluster in the west-ward direction, and which heated the intra-cluster medium, leading to adiabatic compression of the gas behind the 'bullet'. The goal of this paper is to report on the detection of this shock front as revealed by the temperature discontinuity in the X-ray XMM-Newton image, and the edge in the Very Large Array (VLA) radio image. We also report on the detection of a relic source in the north-eastern region of the radio halo in the KAT-7 data, confirming the presence of an extended relic in this cluster. The brightness edge in the X-rays corresponds to a shock front with a Mach number $M= 2.2\pm0.3$, at a distance of 0.2 Mpc from the cluster centre. An estimate from the luminosity jump gives $M=1.9\pm0.4$. We consider a simple explanation for the electrons at the shock front, and for the observed discrepancy between the average spectral index of the radio halo emission and that predicted by the $M=2.2$ shock which precedes the 'bullet'.

description: We perform an amplitude analysis of the decays B0->phi K^*_2(1430)0, phi K^*(892)0, and phi(K pi)^0_S-wave with a sample of about 384 million BBbar pairs recorded with the BABAR detector. The fractions of longitudinal polarization f_L of the vector-tensor and vector-vector decay modes are measured to be 0.853 +0.061-0.069 +-0.036 and 0.506 +-0.040 +-0.015, respectively. Overall, twelve parameters are measured for the vector-vector decay and seven parameters for the vector-tensor decay, including the branching fractions and parameters sensitive to CP-violation.

description: Σκοπός: Προοπτική, παρεμβατική πιλοτική μελέτη με σκοπό τη διερεύνηση της ιστοπαθολογικής και κλινικής επίδρασης αντι-VEGF παράγοντα (ρανιμπιζουμάμπης) στο πρωτοπαθές πτερύγιο σε συνάρτηση με το χρόνο.Υλικό- Μέθοδοι: Πέντε ασθενείς με πρωτοπαθές πτερύγιο υποβλήθηκαν σε μία εφάπαξ ένεση ρανιμπιζουμάμπης (δόση 0,3mg) υπό τον επιπεφυκότα και το πτερύγιο αφαιρέθηκε μετά από τρεις ημέρες, μία εβδομάδα, δύο εβδομάδες, ένα μήνα και δύο μήνες, αντίστοιχα. Φωτογραφίες του πτερυγίου λήφθηκαν αμέσως πριν από την ένεση, μία εβδομάδα μετά την ένεση και την ημέρα της χειρουργικής αφαίρεσης του πτερυγίου. Αποτελέσματα: Κανένας από τους ασθενείς δεν ανέφερε παρενέργειες από την ένεση της ρανιμπιζουμάμπης. Ωστόσο, η ρανιμπιζουμάμπη δεν είχε καμιά επίδραση στην έκταση της αγγείωσης του πτερυγίου, ανεξάρτητα από το χρονικό διάστημα που μεσολάβησε μεταξύ της ένεσης και της χειρουργικής αφαίρεσης του πτερυγίου. Επιπλέον, η ανοσοϊστοχημική εξέταση δεν κατέδειξε διαφορές στην κατανομή του VEGF-A ανάμεσα στα πτερύγια, καθώς και μεταξύ των ασθενών που υποβλήθηκαν στην ένεση και πέντε ασθενών- μαρτύρων με πρωτοπαθές πτερύγιο. Συμπέρασμα: Η χορήγηση ρανιμπιζουμάμπης υπό τον επιπεφυκότα σε μία εφάπαξ δόση των 0,3mg είναι ασφαλής, ωστόσο δεν φαίνεται να έχει επίδραση στην έκταση της αγγείωσης στο πρωτοπαθές πτερύγιο.
description: Purpose: A prospective, interventional pilot study to study the effect of ranibizumab on primary pterygium in respect of time.Methods: Five patients with primary pterygium encroaching onto the cornea received a single subconjunctival injection of ranibizumab (0.3mg) and the pterygium was removed three days, one week, two weeks, one month and two months later, respectively. Digital photographs of the pterygium were taken at the following time points: immediately prior to injection, one week after the injection and on the day of surgical removal. Results: Ranibizumab was well tolerated by all patients and no side-effects were reported. However, clinically it had no effect on the extent of pterygium, regardless of the time elapsed between injection and operation. No regression of pterygium vessels was noted in any of the patients. Immunohistochemical analysis also showed no particular differences in the staining pattern of VEGF-A among the pterygia as well as between the pterygia treated with ranibizumab and five non-treated primary pterygia serving as controls. Conclusion: Subconjunctival ranibizumab at a single dose of 0.3mg is safe but seems to have no effect on the extent of vascularization of primary pterygium.

description: Η αξιολόγηση της ποιότητας του εδάφους αποτελεί σημαντικό εργαλείο για τη σωστή διαχείριση των εδαφικών πόρων με τελικό στόχο την προστασία του περιβάλλοντος και της υγείας του ανθρώπου, των φυτών και των ζώων. Σκοπός της εργασίας ήταν η εφαρμογή ποσοτικοποιημένης μεθόδου αξιολόγησης του βαθμού υποβάθμισης ρυπασμένων περιοχών, στο πλαίσιο της Ευρωπαϊκής Θεματικής Στρατηγικής για τα εδάφη. Το πείραμα έλαβε χώρα στην περιοχή των Ταγαράδων, η οποία επλήγει τον Ιούλιο του 2006, όταν διέρρευσαν διασταλάζοντα λύματα επιβαρυμένα με ρύπους, από λιμνοδεξαμενή της παρακείμενης χωματερής. Έγινε διάνοιξη 20 φρεατίων στην περιοχή που δέχτηκε τον μεγαλύτερο όγκο διασταλάζοντων και λήψη άλλων 20 επιφανειακών δειγμάτων. Ακολούθησαν αναλύσεις στο εργαστήριο για τον έλεγχο της κατάστασης των εδαφικών δεικτών και της παρουσίας βαρέων μετάλλων στο έδαφος. Εφαρμόστηκε μεθοδολογία για την ποσοτική εκτίμηση της εδαφικής ποιότητας και με τη χρήση των Γ.Σ.Π. έγινε χωρική κατανομή της υποβάθμισης της περιοχής με βάση την τιμή της ηλεκτρικής αγωγιμότητας. Η μέθοδος που χρησιμοποιήθηκε, ανταποκρίνεται στα κριτήρια που έχει ορίσει η Θεματική Στρατηγική για τα εδάφη και συντελεί στην πρόληψη, την αποκατάσταση και τον έλεγχο της υποβάθμισης.
description: Soil quality assessment constitutes an important tool for the appropriate management of soil resources aiming at the protection of the environment and health of human, plants and animals. The objective of this work was to implement a quantitative method for assessing the degree of degradation of polluted areas under the framework of Soil Thematic Strategy. The experiment took place in a part of the agricultural area of Tagarades, Greece, which was affected by waste water spilling from the nearby sanitary landfill in July 2006. A total of 20 auger holes were opened for soil sampling and another 20 surface soil samples were taken. Soil samples were analyzed for heavy metals and basic soil properties. A method was proposed and implemented for soil quality quantitative assessment and soil degradation was mapped and zoned using GIS based on electrical conductivity. The proposed method fulfills the criteria posed by the Soil Thematic Strategy of EU and contributes to prevention, restoration and control of soil degradation.

description: Strong selection effects are present in observational samples of cataclysmic variables (CVs), complicating comparisons to theoretical predictions. The selection criteria used to define most CV samples discriminate heavily against the discovery of short-period, intrinsically faint systems. The situation can be improved by selecting CVs for the presence of emission lines. For this reason, we have constructed a homogeneous sample of CVs selected on the basis of Halpha emission. We present discovery observations of the 14 CVs and 2 additional CV candidates found in this search. The orbital periods of 11 of the new CVs were measured; all are above 3 h. There are two eclipsing systems in the sample, and one in which we observed a quasi-periodic modulation on a \sim 1000 s time-scale. We also detect the secondary star in the spectrum of one system, and measure its spectral type. Several of the new CVs have the spectroscopic appearance of nova-like variables (NLs), and a few display what may be SW Sex star behaviour. In a companion paper, we discuss the implications of this new sample for CV evolution.

description: Phase change alloys have seen widespread use from rewritable optical discs to the present day interest in their use in emerging neuromorphic computing architectures. In spite of this enormous commercial interest, the physics of carriers in these materials is still not fully understood. Here, we describe the time and space dependence of the coupling between photoexcited carriers and the lattice in both the amorphous and crystalline states of one phase change material, GeTe. We study this using a time-resolved optical technique called picosecond acoustic method to investigate the \textit{in situ} thermally assisted amorphous to crystalline phase transformation in GeTe. Our work reveals a clear evolution of the electron-phonon coupling during the phase transformation as the spectra of photoexcited acoustic phonons in the amorphous ($a$-GeTe) and crystalline ($α$-GeTe) phases are different. In particular and surprisingly, our analysis of the photoinduced acoustic pulse duration in crystalline GeTe suggests that a part of the energy deposited during the photoexcitation process takes place over a distance that clearly exceeds that defined by the pump light skin depth. In the opposite, the lattice photoexcitation process remains localized within that skin depth in the amorphous state. We then demonstrate that this is due to supersonic diffusion of photoexcited electron-hole plasma in the crystalline state. Consequently these findings prove the existence of a non-thermal transport of energy which is much faster than lattice heat diffusion.

description: X-ray emission from quasars has been detected up to redshift $z=7.5$, although only limited to a few objects at $z>6.5$. In this work, we present new Chandra observations of five $z>6.5$ quasars. By combining with archival Chandra observations of six additional $z>6.5$ quasars, we perform a systematic analysis on the X-ray properties of these earliest accreting supermassive black holes (SMBHs). We measure the black hole masses, bolometric luminosities ($L_{\rm bol}$), Eddington ratios ($λ_{\rm Edd}$), emission line properties, and infrared luminosities ($L_{\rm IR}$) of these quasars using infrared and sub-millimeter observations. Correlation analysis indicates that the X-ray bolometric correction (the factor that converts from X-ray luminosity to bolometric luminosity) decreases with increasing $L_{\rm bol}$, and that the UV/optical-to-X-ray ratio, $α_{\rm ox}$, strongly correlates with $L_{\rm 2500}$, and moderately correlates with $λ_{\rm Edd}$ and blueshift of CIV emission lines. These correlations are consistent with those found in lower-$z$ quasars, indicating quasar accretion physics does not evolve with redshift. We also find that $L_{\rm IR}$ does not correlate with $L_{\rm 2-10 keV}$ in these luminous distant quasars, suggesting that the ratio of the SMBH growth rate and their host galaxy growth rate in these early luminous quasars are different from those of local galaxies. A joint spectral analysis of the X-ray detected $z>6.5$ quasars yields an average X-ray photon index of $ Γ=2.32^{+0.31}_{-0.30}$, steeper than that of low-$z$ quasars. By comparing it with the $Γ-λ_{\rm Edd}$ relation, we conclude that the steepening of $Γ$ for quasars at $z>6.5$ is mainly driven by their higher Eddington ratios.

description: We adopt the deep learning method CASI-3D (Convolutional Approach to Structure Identification-3D) to identify protostellar outflows in molecular line spectra. We conduct magneto-hydrodynamics simulations that model forming stars that launch protostellar outflows and use these to generate synthetic observations. We apply the 3D radiation transfer code RADMC-3D to model 12CO (J=1-0) line emission from the simulated clouds. We train two CASI-3D models: ME1 is trained to predict only the position of outflows, while MF is trained to predict the fraction of the mass coming from outflows in each voxel. The two models successfully identify all 60 previously visually identified outflows in Perseus. Additionally, CASI-3D finds 20 new high-confidence outflows. All of these have coherent high-velocity structures, and 17 of them have nearby young stellar objects, while the remaining three are outside the Spitzer survey coverage. The mass, momentum and energy of individual outflows in Perseus predicted by model MF is comparable to the previous estimations. This similarity is due to a cancelation in errors: previous calculations missed outflow material with velocities comparable to the cloud velocity, however, they compensate for this by over-estimating the amount of mass at higher velocities that has contamination from non-outflow gas. We show outflows likely driven by older sources have more high-velocity gas compared to those driven by younger sources.
