The effect of stellar evolution upon Population II Contact Binaries in the Period-Color Relation. I. Equal-Mass, Marginal Contact Systems

description: Field W UMa binaries observe a well known Period-Color Relation such that systems containing more massive stars are bluer and have longer orbital periods than those systems with lower mass components. However, it has been known for a decade that metal-poor W UMa's are too blue, have too short an orbital period, or both. Correcting the observed color for the reduced line blanketing in the atmosphere of a Pop II star only accounts for part of the observed discrepancy. As others have suggested, and Rucinski (2000) show, the smaller radii of Pop II stars and the correspondingly shorter orbital periods are responsible for the remainder. In this paper I investigate the effect of evolution upon the location in the period-color plane. This paper addresses the restricted case of equal mass components in critical contact with their inner Roche lobes, but should be applicable to the more general cases to the extent that the relative sizes of stellar components are preserved with metallicity changes. The calculated metallicity-age dependent Period-Color Relations substantially agree with Rucinski & Duerbeck's (1997) empirically derived corrections to the Period-Color Relation over most of the investigated range of periods. However, our predictions deviate to a greater degree as stellar age increases since their parameterization does not include the effect of evolution.

title: Die Auswirkungen von Telearbeit auf die informellen Strukturen im Unternehmen
Creators: name: Püler, Julia
Year: 2023

description: In meiner Masterarbeit untersuche ich die Auswirkungen von Telearbeit auf die informellen Strukturen innerhalb des Unternehmens. In acht leitfadengestützten Interviews befrage ich Mitarbeiter:innen aus einem großen österreichischen Unternehmen, zu ihren Erfahrungen mit Telearbeit und den daraus resultierenden Auswirkungen auf Informationsaustausch und Interaktion mit Kolleg:innen. Die gesammelten Daten werte ich anschließend mittels qualitativer Inhaltsanalyse aus, und interpretiere die Ergebnisse in Zusammenhang mit den davor gebildeten Hypothesen. Die Ergebnisse meiner Analyse zeigen, dass Telearbeit eine deutliche Reduktion von informellen Strukturen am Arbeitsplatz bewirkt. Das Kennenlernen neuer Mitarbeiter:innen wird durch das Arbeiten von zu Hause aus erschwert und auch der informelle Kontakt zu bekannten Kolleg:innen wird durch den wegfallenden spontanen Kontakt in den Büroräumlichkeiten verringert. Gezielte Nutzung von digitalen Kommunikationskanälen – wie beispielsweise virtuelle Mittagessen über Microsoft Teams – können informelle Strukturen zwar stärken, sind jedoch kein Ersatz für persönliche Treffen.

description: Just as for non-abelian gauge theories at strong coupling, discrete lattice methods are a natural tool in the study of non-perturbative quantum gravity. They have to reflect the fact that the geometric degrees of freedom are dynamical, and that therefore also the lattice theory must be formulated in a background-independent way. After summarizing the status quo of discrete covariant lattice models for four-dimensional quantum gravity, I describe a new class of discrete gravity models whose starting point is a path integral over Lorentzian (rather than Euclidean) space-time geometries. A number of interesting and unexpected results that have been obtained for these dynamically triangulated models in two and three dimensions make discrete Lorentzian gravity a promising candidate for a non-trivial theory of quantum gravity.

description: The structural features of the interface between the cystalline and amorphous phases of Si solid are studied in simulations based on a combination of empirical interatomic potentials and a nonorthogonal tight-binding model. The tight-binding Hamiltonian was created and tested for the types of structures and distortions anticipated to occur at this interface. The simulations indicate the presence of a number of interesting features near the interface. The features that may lead to crystallization upon heating include <110> chains with some defects, most prominently dimers similar to those on the Si(001) 2x1 reconstructed free surface. Within the amorphous region order is lost over very short distances. By examining six different samples with two interfaces each, we find the energy of the amorphous-crystal interface to be 0.49 +/- 0.05 J/m^2

description: The possibility of constructing a surface exciton polariton (SEP) based sensor at room temperature is explored. The proposed SEP sensor is based on the Kretschmann-Raether configuration of conventional surface plasmon resonance (SPR) sensor, where the metal thin film was replaced by the J-aggregate cyanine dye film. The excitation of SEP results in a strong electric field at the interface of TDBC and analyte, and exponentially decaying into the analyte, which is sensitive to the refractive index variations of analyte. The sensitivity of 118.1818 $^\circ/\text{RIU}$ (140.4286 $^\circ/\text{RIU}$) was achieved for the proposed SEP sensor within the refractive index range 1.0-1.001 (1.33-1.36) of gaseous analyte (aqueous solutions), which is about 2 (3.5) times higher than that of conventional gold-based SPR sensor. The significant superiority of the SEP sensor in sensitivity revealing SEP as a new promising mechanism for sensing applications.

description: In the long-time pursuit of the solution to calculate the partition function (or free energy) of condensed matter, Monte-Carlo-based nested sampling should be the state-of-the-art method, and very recently, we established a direct integral approach that works at least four orders faster. In present work, the above two methods were applied to solid argon at temperatures up to $300$K, and the derived internal energy and pressure were compared with the molecular dynamics simulation as well as experimental measurements, showing that the calculation precision of our approach is about 10 times higher than that of the nested sampling method.

description: Introduction Ecarin clotting assay (ECA) and Russell Viper Venom Assay (RVV) are established to assess coagulation effects of Factor II inhibitor i.e. Dabigatran and Factor Xa inhibitors i.e. Rivaroxaban and Apixaban; respectively. These assays can be conducted on the ClotPro® , which is a point of care (POC) instrument that uses viscoelastometry principles to measure coagulation effects. Objective To determine the coagulation parameter values for ECA and RVV in Malaysian population and compare to the established preliminary reference ranges of ClotPro®. Methodology We recruited healthy volunteers (HV) with ECA and RVV assessment done on the ClotPro® at the Sarawak Heart Center (SHC) between August 2019 to June 2020. The parameters assessed were clotting time (CT) in seconds, clot formation time (CFT) in seconds and maximum clot firmness (MCF) in mm. The parameter values were compared to the preliminary reference ranges (PRR) established on the ClotPro® from 30 blood donors. Results A total of 63 HV were included in the study. Mean age was 25.37 ± 5.24 with a range of 20-46 years old. Discussion The ranges for both ECA and RVV coagulation parameters in our population were wider as compared to the preliminary established reference ranges reported by the manufacturer. The established reference ranges were obtained from Caucasians, which have different physical size, dietary habit, cultural and geographical influences that might affect responses in the coagulation system as compared to Asians. Conclusion As the ECA and RVV coagulation parameter values for our population did not fall into the recommended reference ranges established for the ClotPro® , our study suggested to establish the reference ranges of these parameters specific for our population.

description: This paper presents a comprehensive demonstration of the Pure Time Theory (PTT), a novel framework in which a single scalar field, T_relax(x), governs the emergence of physical laws, spacetime structure, and fundamental constants. We show that this approach explains a wide range of observational anomalies—including excesses at 28 and 95 GeV in CMS data, galactic rotation curves without dark matter, Casimir force deviations, and the spectral shape of the NANOGrav gravitational wave background—using a single scaling parameter β ≈ 1.203. All derivations are first-principles-based, and empirical predictions are matched quantitatively. The model also recovers general relativity as an emergent approximation, unifies electromagnetic and gravitational dynamics, and removes probabilistic postulates from quantum theory. Finally, philosophical implications and theological correspondences are explored, emphasizing a convergence between scientific determinism and metaphysical unity. This article invites replication and verification of its claims and challenges the fragmentation of modern physics with a unified temporal ontology.

description: Abstract

This innovative research delves at the complex dynamics of English language usage in both traditional 'Inner Circle' countries (such as the UK, USA, and Australia) and the Indonesian environment. This analysis explores the intricacies of how English words are used and understood in various linguistic contexts, providing an in-depth exploration of the subtle ways in which English adapts to varied cultural and social situations. It is based on several linguistic theories, such as Linguistic Relativity, Multilingualism, Post-Colonialism, Language Dynamics, Sociolinguistics, Cultural Identity, Globalisation, World Englishes, and Pragmatics. Within Inner Circle countries, English serves as more than just a means of communication; it functions as a cultural marker, impacting social stratification and encompassing unique phonetic characteristics and sociolinguistic elements. In contrast, English in Indonesia represents modernity and worldwide interconnectedness, blending with indigenous languages and cultural conventions. This study examines the patterns of adaptation, localization, and standardisation in both contexts, emphasising the influence of globalisation, social media, and digital communication on language usage and evolution. The results demonstrate notable disparities in the utilisation of particular English phrases in each setting, influenced by cultural subtleties and societal conventions. The study highlights the dynamic nature of language, which continuously changes and adjusts in response to cultural, social, and technological changes. It asserts that comprehending the contextual subtleties of language is vital for successful communication in multilingual environments, hence opening avenues for further investigation into linguistic landscapes, the influence of digital communication, and educational ramifications.

description: PAN is a scientific instrument suitable for deep space and interplanetary missions. It can precisely measure and monitor the flux, composition, and direction of highly penetrating particles ($> \sim$100 MeV/nucleon) in deep space, over at least one full solar cycle (~11 years). The science program of PAN is multi- and cross-disciplinary, covering cosmic ray physics, solar physics, space weather and space travel. PAN will fill an observation gap of galactic cosmic rays in the GeV region, and provide precise information of the spectrum, composition and emission time of energetic particle originated from the Sun. The precise measurement and monitoring of the energetic particles is also a unique contribution to space weather studies. PAN will map the flux and composition of penetrating particles, which cannot be shielded effectively, precisely and continuously, providing valuable input for the assessment of the related health risk, and for the development of an adequate mitigation strategy. PAN has the potential to become a standard on-board instrument for deep space human travel. PAN is based on the proven detection principle of a magnetic spectrometer, but with novel layout and detection concept. It will adopt advanced particle detection technologies and industrial processes optimized for deep space application. The device will require limited mass (~20 kg) and power (~20 W) budget. Dipole magnet sectors built from high field permanent magnet Halbach arrays, instrumented in a modular fashion with high resolution silicon strip detectors, allow to reach an energy resolution better than 10\% for nuclei from H to Fe at 1 GeV/n.

description: Schon vor 1945 war man sich seitens der Alliierten darin einig gewesen, Österreich in den Grenzen von 1937 aus dem Deutschen Reich herauszulösen und entnazifizieren zu wollen. Identitätsstiftende und redemokratisierende Maßnahmen für die Bevölkerung, welche 1933 in eine Diktatur geschlittert war, nur um 1938 in die nächste zu taumeln, waren unabdingbar. Die Suche nach einer noch nie dagewesenen österreichischen Identität musste demnach zwingend unter völliger Abnabelung von Nazideutschland erfolgen. In Moskau hatte man bereits einen Plan entworfen, wie dies mittels der Besinnung auf österreichische Glanzleistungen im politisch unverfänglichen Bereich von Kunst und Kultur gelingen sollte. Kultur- und bildungspolitische Kontexte stehen in engem Zusammenhang mit Geopolitik. Mittels Analyse zahlreicher zeitgenössischer Zeitungsartikel, einem beträchtlichen Fundus an Literatur und mehreren Stunden an Zeitzeugeninterviews hat diese Arbeit ein Destillat ergeben, das Aussagen darüber erlaubt, welche kulturpolitischen Schwerpunkte die Sowjets in Wien – auch in enger Abstimmung mit der österreichischen Bundesregierung – setzten. Beim Abnabelungsprozess ging man schließlich sogar so weit, die Frage nach der österreichischen Mitverantwortung aus der Präambel des Staatsvertrags zu streichen. So konnten Schöpfungsmythen um das Entstehen der Zweiten Republik entstehen, die – jahrzehntelang tradiert – dazu beitrugen, ein Nationalgedächtnis zu konstruieren, welches auf höchst origineller Interpretation der eigenen Vergangenheit beruht: Österreich, als erstes Hitler-Opfer und führende deutsche Kulturnation, sollte rückwärtsgewandt nach vorne in eine restaurative Zukunft blicken.

description: Charge dynamics of the two-dimensional Hubbard model is investigated. Lancz$\ddot{\rm o}$s-diagonalization results for the optical conductivity and the Drude weight of this model are presented. Near the Mott transition, large incoherence below the upper-Hubbard band is obtained together with a remarkably suppressed Drude weight in two dimensions while the clearly coherent character is shown in one dimension. The two-dimensional results are consistent with previous results from quantum Monte Carlo calculations indicating that the Mott transition in this two-dimensional model belongs to the universality class characterized by the dynamical exponent of $z=4$.

Adopting the Landau level bosonization technique developed in previous papers, we find an exact expression for the relative intensities of spectral lines. Their envelope function, governed by the interaction between the electron gas and the core hole, is reminescent of the famous Fermi edge singularity, which is recovered in the limit of a vanishing magnetic field.

description: In earlier work it was pointed out that for warped product spacetimes the conformal (geometrical moduli) excitations of the internal compactified factor spaces should be observable as massive scalar fields in the external spacetime. Here we show that these scalar fields (gravitational excitons) describe weakly interacting particles and can be considered as dark matter component. Masses of the gravexcitons are defined by the form of the effective potential of the theory and the stabilization scales of the internal space. This implies that different stabilization scales result in different types of DM. An essential role is played by the effective potential. On the one hand, its minima fix possible stabilization scales of the internal spaces; on the other hand, they provide possible values for the effective cosmological constant.

description: Advances in quantum computing require high-precision timing instrumentation, whether for photon coincidence detection, quantum entanglement verification, or quantum network synchronization.

This presentation explores the role of precision timing electronics in quantum experiments, particularly focusing on Swabian Instruments' Time Taggers. Swabian Instruments is a company based in Stuttgart, Germany, that specializes in timing electronics for applications requiring very precise time resolution measurements, including time-correlated single photon counting (TCSPC), remote synchronization protocols, and phase & frequency characterization. TCSPC experiments are crucial for breakthroughs in quantum technology, life sciences, and optical communication. Swabian Instruments is already revolutionizing the field by working with top institutions worldwide including NASA, MIT, Harvard, Cambridge, Oxford, and Max Planck Institute, amongst others.

In this talk, we will discuss some of the key applications in which the Time Taggers are used, including quantum heralded measurements, Linear Optics Quantum Information experiments, and distributed quantum network applications. We will cover some of the key challenges, such as photon timing jitter, coincidence counting, and synchronization across multiple nodes, and demonstrate how Swabian Instruments' state-of-the-art time tagging solutions can overcome these obstacles.

Dr. Mirco Kolarczik is the Head of Research & Applications at Swabian Instruments, based in the headquarters in Stuttgart, Germany. Dr. Kolarczik has a PhD in Physics from the Technical University of Berlin, and has been working at Swabian Instruments for almost 6 years.

description: A population transfer based on adiabatic evolutions in a three-state system undergoing an avoided crossing is considered. The efficiency of the process is analyzed in connection with the relevant parameters, bringing to light an important role of the phases of the coupling constants. The role of dissipation is also taken into account, focusing on external decays that can be described by effective non-Hermitian Hamiltonians. Though the population transfer turns out to be quite sensitive to the decay processes, for very large decay rates the occurrence of a Zeno-phenomenon allows for restoring a very high efficiency.

description: We present images from a space-VLBI survey using the facilities of the VLBI Space Observatory Programme (VSOP), drawing our sample from the well-studied Pearson-Readhead survey of extragalactic radio sources. Our survey has taken advantage of long space-VLBI baselines and large arrays of ground antennas, such as the Very Long Baseline Array and European VLBI Network, to obtain high resolution images of 27 active galactic nuclei, and to measure the core brightness temperatures of these sources more accurately than is possible from the ground. A detailed analysis of the source properties is given in accompanying papers. We have also performed an extensive series of simulations to investigate the errors in VSOP images caused by the relatively large holes in the (u,v) plane when sources are observed near the orbit normal direction. We find that while the nominal dynamic range (defined as the ratio of map peak to off-source error) often exceeds 1000:1, the true dynamic range (map peak to on-source error) is only about 30:1 for relatively complex core-jet sources. For sources dominated by a strong point source, this value rises to approximately 100:1. We find the true dynamic range to be a relatively weak function of the difference in position angle (PA) between the jet PA and (u,v) coverage major axis PA. For low signal-to-noise regions typically located down the jet away from the core, large errors can occur, causing spurious features in VSOP images that should be interpreted with caution.

description: We have measured the surface impedance of thick superconductors in the mixed state over a broad 2 kHz - 20 MHz frequency range. The depinning cross-over is observed; but it is much broader than expected from classical theories of pinning. A striking result is the existence of size effects which invalidate the common interpretation of the low-frequency surface inductance in terms of a single penetration depth. Instead, a two-mode description of vortex dynamics, assuming free vortex flow in the bulk and surface pinning, accounts quantitatively for the spectrum of the complex apparent penetration depth.

Difficulties in the description of Drell-Yan processes at moderate invariant mass and high transverse momentum

description: We study the Drell-Yan cross section differential with respect to the transverse momentum of the produced lepton pair. We consider data with moderate invariant mass Q of the lepton pair, between 4.5 GeV and 13.5 GeV, and similar (although slightly smaller) values of the transverse momentum q_T. We approach the problem by deriving predictions based on standard collinear factorization, which are expected to be valid toward the high-q_T end of the spectrum and to which any description of the spectrum at lower q_T using transverse-momentum dependent parton distributions ultimately needs to be matched. We find that the collinear framework predicts cross sections that in most cases are significantly below available data at high q_T. We discuss additional perturbative and possible non-perturbative effects that increase the predicted cross section, but not by a sufficient amount.

Optomechanical quadrature squeezing in the non-Markovian regime

description: Squeezing of quantum fluctuation plays an important role in fundamental quantum physics and has marked influence on ultrasensitive detection. We propose a scheme to generate and enhance the squeezing of mechanical mode by exposing the optomechanical system to a non-Markovian environment. It is shown that the effective parametric resonance term of mechanical mode can be induced due to the interaction with cavity and non-Markovian reservoir, thus resulting in quadrature squeezing of the mechanical resonator. And jointing the two kinds of interactions can enhance the squeezing effect. Comparing with the usual Markovian regime, we can obtain stronger squeezing, and significantly the squeezing can approach a low asymptotic stable value.
Comment on "Conductance fluctuations in mesoscopic normal-metal/superconductor samples"

description: Recently, Hecker et al. [Phys. Rev. Lett. 79, 1547 (1997)] experimentally studied magnetoconductance fluctuations in a mesoscopic Au wire connected to a superconducting Nb contact. They claimed to have observed an enhancement of the rms magnitude of these conductance fluctuations in the superconducting state (rms(Gns)) relative to that in the normal state (rms(Gn)) by a factor of 2.8. In this comment, we argue that the measured rms(Gns) is NOT significantly enhanced compared to rms(Gn) when we correct for the presence of an incoherent series resistance from the contacts, which is different when Nb is in the superconducting or normal state.

Observation of field induced anomalous quantum criticality in Ce0.6Y0.4NiGe2 compound

description: We report the results of our investigation of magnetization and heat capacity on a series of compounds Ce1-xYxNiGe2 (x = 0.1, 0.2 and 0.4) under the influence of external magnetic field. Our studies of the thermodynamic quantity -dM/dT on these compounds indicate that magnetic frustration persists in Ce0.9Y0.1NiGe2, as also reported for the parent compound CeNiGe2. The weak signature of this frustration is also noted in Ce0.8Y0.2NiGe2, whereas, it is suppressed in Ce0.6Y0.4NiGe2. Heat capacity studies on Ce0.9Y0.1NiGe2 and Ce0.8Y0.2NiGe2 indicate the presence of a new magnetic anomaly at high field which indicates that quantum criticality is absent in these compounds. However, for Ce0.6Y0.4NiGe2 such an anomaly is not noted. For this later compound, the magnetic field (H) and temperature (T) dependence of heat capacity and magnetization obey H/T scaling above critical fields. However, the obtained scaling critical parameter (δ) is 1.6, which is away from mean field value of 3. This deviation suggests the presence of unusual fluctuations and anomalous quantum criticality in these compounds. This unusual fluctuation may arise from disorderness induced by Y-substitution.

Small strange stars and marginally stable orbit in Newtonian theory

description: It is shown that for very rapidly rotating low mass strange stars the marginally stable orbit is located above the stellar surface. This effect is explained by the very important role of the oblateness of the rotating strange star. The comparison with some ``academic'' examples is presented. This feature is purely Newtonian in its nature and has nothing to do with relativistic marginally stable orbit. The effect is very large and cannot be treated in a perturbative way. It seems that strange stars as a very dense self-bound objects are the only possibility in Nature to represent these toy models.

description: DIRECT is a project to obtain directly the distances to two Local Group galaxies, M31 and M33, which occupy a crucial position near the bottom of the cosmological distance ladder. As the first step of the DIRECT project we have searched for detached eclipsing binaries (DEBs) and new Cepheids in the M31 and M33 galaxies with 1m-class telescopes. In this seventh paper we present a catalog of variable stars discovered in the data from the followup observations of DEB system D33J013346.2+304439.9 in field M33A [(RA,Dec)= (23.55, 30.72), J2000.0], collected with the Kitt Peak National Observatory 2.1m telescope. In our search covering an area of 108 sq. arcmin. we have found 434 variable stars: 63 eclipsing binaries, 305 Cepheids, and 66 other periodic, possible long period or non-periodic variables. Of these variables 280 are newly discovered, mainly short-period and/or faint Cepheids. Their light curves were extracted using the ISIS image subtraction package. For 85% of the variables we present light curves in standard V and B magnitudes, with the remaining 15% expressed in units of differential flux. We have discovered a population of first overtone Cepheid candidates and for eight of them we present strong arguments in favor of this interpretation. We also report on the detection of a non-linearity in the KPNO T2KA and T1KA cameras. The catalog of variables, as well as their photometry (about 7.8*10^4 BV measurements) and finding charts, is available electronically via anonymous ftp and the World Wide Web. The complete set of the CCD frames is available upon request.

description: Conventional approaches to probing axions and axion-like particles (ALPs) typically rely on a coupling to photons. However, if this coupling is extremely weak, ALPs become invisible and are effectively decoupled from the Standard Model. Here we show that such invisible axions, which are viable candidates for dark matter, can produce a stochastic gravitational wave background in the early universe. This signal is generated in models where the invisible axion couples to a dark gauge boson that experiences a tachyonic instability when the axion begins to oscillate. Incidentally, the same mechanism also widens the viable parameter space for axion dark matter. Quantum fluctuations amplified by the exponentially growing gauge boson modes source chiral gravitational waves. For axion decay constants $f \gtrsim 10^{17}$ GeV, this signal is detectable by either pulsar timing arrays or space/ground-based gravitational wave detectors for a broad range of axion masses, thus providing a new window to probe invisible axion models.
