description: Early-time observations of Type Ia supernovae (SNe Ia) are essential to constrain their progenitor properties. In this paper, we present high-quality light curves of 127 SNe Ia discovered by the Zwicky Transient Facility (ZTF) in 2018. We describe our method to perform forced point spread function (PSF) photometry, which can be applied to other types of extragalactic transients. With a planned cadence of six observations per night ($3g+3r$), all of the 127 SNe Ia are detected in both $g$ and $r$ band more than 10\,d (in the rest frame) prior to the epoch of $g$-band maximum light. The redshifts of these objects range from $z=0.0181$ to 0.165; the median redshift is 0.074. Among the 127 SNe, 50 are detected at least 14\,d prior to maximum light (in the rest frame), with a subset of 9 objects being detected more than 17\,d before $g$-band peak. This is the largest sample of young SNe Ia collected to date; it can be used to study the shape and color evolution of the rising light curves in unprecedented detail. We discuss six peculiar events in this sample, including one 02cx-like event ZTF18abclfee (SN\,2018crl), one Ia-CSM SN ZTF18aaykjei (SN\,2018cxk), and four objects with possible super-Chandrasekhar mass progenitors: ZTF18abhpgje (SN\,2018eul), ZTF18abdpvnd (SN\,2018dvf), ZTF18aawpcel (SN\,2018cir) and ZTF18abddmrf (SN\,2018dsx).

description: Most microscopic pedestrian navigation models use the concept of "forces" applied to the pedestrian agents to replicate the navigation environment. While the approach could provide believable results in regular situations, it does not always resemble natural pedestrian navigation behaviour in many typical settings. In our research, we proposed a novel approach using reinforcement learning for simulation of pedestrian agent path planning and collision avoidance problem. The primary focus of this approach is using human perception of the environment and danger awareness of interferences. The implementation of our model has shown that the path planned by the agent shares many similarities with a human pedestrian in several aspects such as following common walking conventions and human behaviours.
How do sound waves in a Bose-Einstein condensate move so fast?

description: Low-momentum excitations of a dilute Bose-Einstein condensate behave as phonons and move at a finite velocity v_s. Yet the atoms making up the phonon excitation each move very slowly; v_a = p/m --> 0. A simple "cartoon picture" is suggested to understand this phenomenon intuitively. It implies a relation v_s/v_a = N_ex, where N_ex is the number of excited atoms making up the phonon. This relation does indeed follow from the standard Bogoliubov theory.

Directional dependence of the Unruh effect for spatially extended detectors

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We analyse the response of a spatially extended direction-dependent local quantum system, a detector, moving on the Rindler trajectory of uniform linear acceleration in Minkowski spacetime, and coupled linearly to a quantum scalar field. We consider two spatial profiles: (i) a profile defined in the Fermi-Walker frame of an arbitrarily-accelerating trajectory, generalising the isotropic Lorentz-function profile introduced by Schlicht to include directional dependence; and (ii) a profile defined only for a Rindler trajectory, utilising the associated frame, and confined to a Rindler wedge, but again allowing arbitrary directional dependence. For (i), we find that the transition rate on a Rindler trajectory is non-thermal, and dependent on the direction, but thermality is restored in the low and high frequency regimes, with a direction-dependent temperature, and also in the regime of high acceleration compared with the detector's inverse size. For (ii), the transition rate is isotropic, and thermal in the usual Unruh temperature. We attribute the non-thermality and anisotropy found in (i) to the leaking of the Lorentz-function profile past the Rindler horizon.

The Structure of the [Zn_In - V_P] Defect Complex in Zn Doped InP

Year: 2003

description: We study the structure, the formation and binding energies and the transfer levels of the zinc-phosphorus vacancy complex [Zn_In - V_P] in Zn doped p-type InP, as a function of the charge, using plane wave ab initio DFT-LDA calculations in a 64 atom supercell. We find a binding energy of 0.39 eV for the complex, which is neutral in p-type material, the 0/-1 transfer level lying 0.50 eV above the valence band edge, all in agreement with recent positron annihilation experiments. This indicates that, whilst the formation of phosphorus vacancies (V_P) may be involved in carrier compensation in heavily Zn doped material, the formation of Zn-vacancy complexes is not. Regarding the structure: for charge states Q=+6 to -4 the Zn atom is in an sp^2 bonded DX position and electrons added/removed go to/come from the remaining dangling bonds on the triangle of In atoms. This reduces the effective vacancy volume monatonically as electrons are added to the complex, also in agreement with experiment. The reduction occurs through a combination of increased In-In bonding and increased Zn-In electrostatic attraction. In addition, for certain charge states we find complex Jahn-Teller behaviour in which up to three different structures, (with the In triangle dimerised, antidimerised or symmetric) are stable and are close to degenerate. We are able to predict and successfully explain the structural behaviour of this complex using a simple tight binding model.

Spectral statistics of multi-parametric Gaussian ensembles with chiral symmetry

description: The statistics of chiral matrix ensembles with uncorrelated but multivariate Gaussian distributed elements is intuitively expected to be driven by many parameters. Contrary to intuition, however, our theoretical analysis reveals the existence of a single parameter, a function of all ensemble parameters, which governs the dynamics of spectral statistics. The analysis not only extends the similar formulation (known as complexity parameter formulation) for the Hermitian ensembles without chirality to those with it but also reveals the underlying connection between chiral complex systems with seemingly different system conditions as well as to other complex systems e.g. multi-parametric Wishart ensembles as well as generalized Calogero Sutherland Hamiltonian (CSH).

Spiral order induced by distortion in frustrated square-lattice antiferromagnet

Year: 2003
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: In a strongly frustrated square-lattice antiferromagnet with diagonal coupling J', for J/(2J') < 1, an incommensurate spiral state with propagation vector Q = (π+/- δ, π+/- δ) near (π,π) competes closely with the Neel collinear antiferromagnetic ground state. For classical Heisenberg spins the energy of the spiral state can be lowered as it adapts to the distortion of the crystal lattice. As a result, a weak superstructural modulation such as exist in doped cuprates might stabilize an incommensurate spiral phase for some range of the parameter J/(2J') close to 1.

description: Off-nucleus active galactic nuclei (AGN) can be signposts of inspiraling supermassive black holes (SMBHs) on galactic scales, or accreting SMBHs recoiling after the coalescence of a SMBH binary or slingshot from three-body interactions. Because of the stochastic variability of AGN, the measured photocenter of an unresolved AGN-host system will display astrometric jitter that depends on the off-nucleus distance of the AGN, the total photometric variability of the system, and the AGN-host contrast. Here we use the precision astrometry from Gaia DR2 to constrain the off-nucleus population of a low-redshift (0.399% of AGN to be well-centered below 500 parsec. These results suggest that genuine off-nucleus AGN (offset by > a few hundred pc) must be rare at low redshift. Future Gaia releases of time series of photocenter and flux measurements, improved treatments for extended sources and longer baselines will further tighten these constraints, and enable a systematic full-sky search for rare off-nucleus AGN on ~ 10-1000 pc scales.

Metal-insulator transition in two-dimensional electron systems

Year: 2003

description: The interplay between strong Coulomb interactions and randomness has been a long-standing problem in condensed matter physics. According to the scaling theory of localization, in two-dimensional systems of noninteracting or weakly interacting electrons, the ever-present randomness causes the resistance to rise as the temperature is decreased, leading to an insulating ground state. However, new evidence has emerged within the past decade indicating a transition from insulating to metallic phase in two-dimensional systems of strongly interacting electrons. We review earlier experiments that demonstrate the unexpected presence of a metallic phase in two dimensions, and present an overview of recent experiments with emphasis on the anomalous magnetic properties that have been observed in the vicinity of the transition.

Στο γενικό μέρος του παρόντος πονήματος παρουσιάζονται ορισμένα γενικά στοιχεία που αφορούν τη χειρουργική των τρίτων γομφίων, όπως η συχνότητα και οι τύποι έγκλεισης, οι ενδείξεις, οι αντενδείξεις και οι επιπλοκές της εξαγωγής τους. Η μελέτη πραγματοποιήθηκε στην κλινική της Στοματικής και Γναθοπροσωπικής Χειρουργικής (ΣΓΠΧ) του Αριστοτελείου Πανεπιστημίου Θεσσαλονίκης (Α.Π.Θ.). Έγινε καταγραφή των ιστορικών των ασθενών που προσήλθαν στην κλινική, σε διάστημα δύο ετών. Η πιο συχνή αιτία προσέλευσης των ασθενών στην κλινική ήταν ο πόνος με ποσοστό 59,66%, ενώ μόλις το 5,7% των ασθενών απευθύνθηκε στην κλινική για προληπτικό έλεγχο. Η πιο συχνή αιτία εξαγωγής εγκλείστου ήταν η περιστεφανίτιδα, με ποσοστό 62,41%. Συμπερασματικά, παρατηρήθηκε ότι, ως επί το πλείστον, η εξαγωγή των τρίτων γομφίων αντιμετωπίζεται σε μεγαλύτερο ποσοστό όταν εμφανίζονται συμπτώματα, τα οποία κινητοποιούν τον ασθενή να αναζητήσει εξειδικευμένη θεραπευτική αντιμετώπιση
description: This study is a retrospective statistical analysis, which draws conclusions mainly about the reason for the arrival of patients, but also the final cause of extraction of the third molars of the upper and lower jaw. In the general part, are recorded some general characteristics that concern the third molar surgery, such as the frequency and types of impaction, indications, contraindications and also complications of their extraction. The study was performed at the Clinic of Oral and Maxillofacial Surgery (STS) of the Aristotle University of Thessaloniki (AUTh). The histories of the patients who came to the clinic over a period of two years were recorded. The most common reason for patients to come to the clinic was pain with a rate of 59.66%, while only 5.7% of patients went to the clinic for routine check-up. The most common cause of extraction was pericoronitis, with a rate of 62.41%. Second, in frequency, cause of extraction is caries, with a percentage of 14.04%. The percentages, both in the cause of attendance due to a previous unsuccessful extraction attempt and in the cause of extraction due to a previous unsuccessful attempt, appear to be the same as in the case of an emergency in which patients came to the clinic. In conclusion, it was observed that, for the most part, the extraction of the third molars is treated to a greater extent when symptoms appear, which motivate the patient to seek specialized treatment

description: We determined zirconium abundance in the atmospheres of 327 red giant branch (RGB) stars in the globular cluster 47 Tuc. The 1D LTE abundances were obtained from the archival VLT GIRAFFE spectra, using 1D hydrostatic ATLAS9 stellar model atmospheres and synthetic Zr I line profiles computed with the SYNTHE package. The average zirconium abundance determined in the sample of RGB stars, [Zr/Fe] = +0.38 +/- 0.12, agrees well with zirconium abundances obtained at this metallicity in the Galactic field stars, as well as with those observed in other Galactic globular clusters.

description: Η διεξαγωγή των διπλών εκλογών του Μαΐου 2019, ευρωπαϊκών και αυτοδιοικητικών, υπερέβη τα συνήθη χαρακτηριστικά κομματικού ανταγωνισμού και κοινωνικού ενδιαφέροντος προσομοιάζοντας το πεδίο διεξαγωγής τους σε ‘’εκλογές πρώτης τάξης’’. Η προοπτική ολοκλήρωσης του εκλογικού κύκλου της κυβέρνησης επιπρόσθετα προσέδωσε ιδιαίτερα χαρακτηριστικά ανταγωνισμού και εκλογικής κινητοποίησης. Η εκλογική κινητοποίηση, ως έκφραση πολιτικής συμμετοχής, συγκροτείται ως ατομική αναπαράσταση και τάση κομματικής επιλογής σημαντικά από την περιρρέουσα κοινωνική ατζέντα μέσα από διαύλους επικοινωνίας τυπικούς και άτυπους. Ο ρόλος της τηλεόρασης, παρά την αμφισβήτηση της κυριαρχίας της στον καθορισμό μιας δημόσιας κοινωνικής και πολιτικής ατζέντας, αποτελεί μια σημαντική παράμετρο επιρροής στη διαμόρφωση της δημόσιας ατζέντας και δεδομένης της πολιτικής συγκυρίας, συνιστά δυνητικά έναν ισχυρό πόλο επιρροής μέσα από μια πολυσήμαντη εργαλειακή διαχείριση της πληροφορίας. Η διπλωματική εργασία επικεντρώνεται ερευνητικά στην καταγραφή όψεων συγκρότησης της πολιτικής ατζέντας στους τηλεοπτικούς σταθμούς ΕΡΤ1 και ΣΚΑΪ κατά την προεκλογική περίοδο στα κεντρικά δελτία ειδήσεων και αναζήτησης πεδίων που συνιστούν μια ενεργητική διαμεσολάβηση σε ένα διεξαγόμενο πολιτικό ανταγωνισμό
description: The conduct of the double, European and local, elections in May 2019, exceeded the usual characteristics of competition between parties and social interest, with their field simulating to that of ''first order elections''. Furthermore, the prospect of completing the government's electoral cycle provided highly competitive features and remarkable electoral mobilization. Electoral mobilization, as an expression of political participation, is composed as an individual representation and a tendency of party choice, significantly affected by the current social agenda through formal and informal communication channels. The role of television, despite the questioning of its dominance in setting a public social and political agenda, is an important factor, influencing the shaping of the public agenda and, given the political situation, constitutes a powerful influence through its polysemic dehumanizing information management. The thesis, from a research perspective, focuses on the recording of aspects of the formation of the political agenda by ERT1 and SKAI television channels during the pre-election period, in the primetime newscast, and on the field search, which constitute an active mediation in an ongoing political competition

description: The objective of this paper is to examine an empirical example of how misleading inferences may be when using aggregate averages in an attempt to understand the general effects of current conditions or changes in Government farm programs. Although contiguous distributional data is not developed, the position taken in this analysis is that (1) the production structure is so diverse that general observations and information constructed from secondary ,data are often inadequate to properly evaluate the effect of agricultural programs, but (2) some central tendencies exist within the production structure so that some meaningful delineations can be made with adequate stratification. It is contended that a relevant delineations must include data pertaining to the ownership of major resources used in production and the debt structure of farm resource owners and users.

description: A first-principles-derived approach is developed to study the effects of uncompensated depolarizing electric fields on the properties of Pb(Zr,Ti)O$_3$ ultrathin films for different mechanical boundary conditions. A rich variety of ferroelectric phases and polarization patterns is found, depending on the interplay between strain and amount of screening of surface charges. Examples include triclinic phases, monoclinic states with in-plane and/or out-of-plane components of the polarization, homogeneous and inhomogeneous tetragonal states, as well as, peculiar laminar nanodomains.

description: Quality evaluation of herbal drugs requires the assessment of identity and possible adulterations, as well as the determination of the content of active principles or markers. For that, normally, different methods, using different chromatographic techniques are prescribed in the Pharmacopeia monographs. The goal of this work is to propose a new method for evaluation, based on “comprehensive high-performance thin layer chromatography (HPTLC) fingerprinting.” A single HPTLC analysis, which combines identification of Ganoderma lucidum fruiting body with a test for adulteration and quantitative determination of the content of total triterpene acids is proposed. Parameters of the HPTLC method were optimized for simplicity, and robustness. Then, 50 samples of G. lucidum fruiting body, plus samples of possible adulterating species were evaluated, proving specificity of the method for the targeted species. Triterpene acids were assayed by integrating the peaks of ganoderic acids in the fingerprint, summing their areas, and quantifying them against a single level calibration point of ganoderic acid A. The presented HPTLC method offers an economic yet powerful alternative to the current USP monograph on G. lucidum fruiting body. It combines identification and quantitative assessment in a single, low-cost test, eliminating the UHPLC assay of total triterpene acids. This way the samples’ quality can be comprehensively described.

description: We regard explanations as a blending of the input sample and the model's output and offer a few definitions that capture various desired properties of the function that generates these explanations. We study the links between these properties and between explanation-generating functions and intermediate representations of learned models and are able to show, for example, that if the activations of a given layer are consistent with an explanation, then so do all other subsequent layers. In addition, we study the intersection and union of explanations as a way to construct new explanations.
The Orbital Period of the Ultracompact Low-Mass X-Ray Binary 4U 1543--624

description: We report the discovery of the orbital period of the ultracompact low-mass X-ray binary (LMXB) 4U 1543-624 using time-resolved optical photometry taken with the 6.5-m Clay (Magellan II) telescope in Chile. The light curve in the Sloan r' band clearly shows a periodic, sinusoidal modulation at 18.2+-0.1 min with a fractional semiamplitude of 8%, which we identify as the binary period. This is the second shortest orbital period among all the known LMXBs, and it verifies the earlier suggestion of 4U 1543-624 as an ultracompact binary based on X-ray spectroscopic properties. The sinusoidal shape of the optical modulation suggests that it arises from X-ray heating of the mass donor in a relatively low-inclination binary, although it could also be a superhump oscillation in which case the orbital period is slightly shorter. If the donor is a C-O white dwarf as previously suggested, its likely mass and radius are around 0.03 M_sun and 0.03 R_sun, respectively. For conservative mass transfer onto a neutron star and driven by gravitational radiation, this implies an X-ray luminosity of 6.5X10^36 erg/s and a source distance of 7 kpc. We also discuss optical photometry of another LMXB, the candidate ultracompact binary 4U 1822-000. We detected significant optical variability on a time scale of about 90 min, but it is not yet clear whether this was due to a periodic modulation.
