description: In the article, we assume the two scalar nonet mesons below and above 1 GeV are all $\bar{q}q$ states, in case I, the scalar mesons below 1 GeV are the ground states, in case II, the scalar mesons above 1 GeV are the ground states. We calculate the $B-S$ form-factors by taking into account the perturbative ${\mathcal{O}}(α_s)$ corrections to the twist-2 terms using the light-cone QCD sum rules and fit the numerical values of the form-factors into the single-pole forms, which have many phenomenological applications.

description: Ultra-high energy cosmic rays can propagate diffusively in cosmic magnetic fields. When their propagation time is comparable to the age of the universe, a suppression in the flux relative to the case in the absence of magnetic fields will occur. In this work we find an approximate parametrization for this suppression for energies below $\sim$ Z EeV using several magnetic field distributions obtained from cosmological simulations of the magnetized cosmic web. We assume that the magnetic fields have a Kolmogorov power spectrum with the field strengths distributed according to these simulations. We show that, if magnetic fields are coupled to the matter distribution, low field strengths will fill most of the volume, making the suppression milder compared to the case of a constant magnetic field with strength equal to the mean value of this distribution. We also derive upper limits for this suppression to occur for some models of extragalactic magnetic fields, as a function of the coherence length of these fields.

description: Chiral symmetry breaking is ubiquitous in biological systems, from DNA to bacterial suspensions. A key unresolved problem is how chiral structures may spontaneously emerge from achiral interactions. We study a simple model of bacterial suspensions in three dimensions that effectively incorporates active motion and hydrodynamic interactions. We perform large-scale molecular dynamics simulations (up to $10^6$ particles) and describe stable (or long-lived metastable) collective states that exhibit chiral organization although the interactions are achiral. We elucidate under which conditions these chiral states will emerge and grow to large scales. We also study a related equilibrium model that clarifies the role of orientational fluctuations.

description: Understanding the interfacial electrical properties between metallic electrodes and low dimensional semiconductors is essential for both fundamental science and practical applications. Here we report the observation of thickness reduction induced crossover of electrical contact at Au/MoS2 interfaces. For MoS2 thicker than 5 layers, the contact resistivity slightly decreases with reducing MoS2 thickness. By contrast, the contact resistivity sharply increases with reducing MoS2 thickness below 5 layers, mainly governed by the quantum confinement effect. It is found that the interfacial potential barrier can be finely tailored from 0.3 to 0.6 eV by merely varying MoS2 thickness. A full evolution diagram of energy level alignment is also drawn to elucidate the thickness scaling effect. The finding of tailoring interfacial properties with channel thickness represents a useful approach controlling the metal/semiconductor interfaces which may result in conceptually innovative functionalities.

We find that the resummation effects reduce the scale uncertainty significantly and decrease the QCD NLO results by about $11\%$ in the large $p_T$ region. The finite top quark mass effects and the effects of the NNLO singular terms are also discussed.

description: We construct higher order rogue wave solutions and breather profiles for the quasi-one-dimensional Gross-Pitaevskii equation with a time-dependent interatomic interaction and external trap through the similarity transformation technique. We consider three different forms of traps, namely (i) time-independent expulsive trap, (ii) time-dependent monotonous trap and (iii) time-dependent periodic trap. Our results show that when we change a parameter appearing in the time-independent or time-dependent trap the second and third-order rogue waves transform into the first-order like rogue waves. We also analyze the density profiles of breather solutions. Here also we show that the shapes of the breathers change when we tune the strength of trap parameter. Our results may help to manage rogue waves experimentally in a BEC system.

description: We construct the simplest gravitational dual model of a superconductor on Q-lattices. We analyze the condition for the existence of a critical temperature at which the charged scalar field will condense. In contrast to the holographic superconductor on ionic lattices, the presence of Q-lattices will suppress the condensate of the scalar field and lower the critical temperature. In particular, when the Q-lattice background is dual to a deep insulating phase, the condensation would never occur for some small charges. Furthermore, we numerically compute the optical conductivity in the superconducting regime. It turns out that the presence of Q-lattice does not remove the pole in the imaginary part of the conductivity, ensuring the appearance of a delta function in the real part. We also evaluate the gap which in general depends on the charge of the scalar field as well as the Q-lattice parameters. Nevertheless, when the charge of the scalar field is relatively large and approaches the probe limit, the gap becomes universal with $ω_g \simeq 9T_c$ which is consistent with the result for conventional holographic superconductors.

Buckling of a beam extruded into highly viscous fluid

description: Inspired by microscopic paramecies which use trichocyst extrusion to propel themselves away from thermal aggressions, we propose a macroscopic experiment to study the stability of a slender beam extruded in a highly viscous fluid. Piano wires were extruded axially at constant speed in a tank filled with corn syrup. The force necessary to extrude the wire was measured to increase linearly at first until the compressive viscous force causes the wire to buckle. A numerical model, coupling a lengthening elastica formulation with resistive force theory, predicts a similar behaviour. The model is used to study the dynamics at large time when the beam is highly deformed. It is found that at large time, a large deformation regime exists in which the force necessary to extrude the beam at constant speed becomes constant and length-independent. With a proper dimensional analysis, the beam can be shown to buckle at a critical length based on the extrusion speed, the bending rigidity and the dynamic viscosity of the fluid. Hypothesising that the trichocysts of paramercies must be sized to maximise their thrust per unit volume as well as avoid buckling instabilities, we predict that their bending rigidity must be about $3\times 10^{-9}~\mathrm{N\cdot μm^2}$. The verification of this prediction is left for future work.

description: Building on the symmetry classification of disordered fermions, we give a proof of the proposal by Kitaev, and others, for a "Bott clock" topological classification of free-fermion ground states of gapped systems with symmetries. Our approach differs from previous ones in that (i) we work in the standard framework of Hermitian quantum mechanics over the complex numbers, (ii) we directly formulate a mathematical model for ground states rather than spectrally flattened Hamiltonians, and (iii) we use homotopy-theoretic tools rather than K-theory. Key to our proof is a natural transformation that squares to the standard Bott map and relates the ground state of a d-dimensional system in symmetry class s to the ground state of a (d+1)-dimensional system in symmetry class s+1. This relation gives a new vantage point on topological insulators and superconductors.

description: In this paper it is presented a manifestly covariant formulation of the Aharonov-Bohm (AB) phase difference for the magnetic AB effect . This covariant AB phase is written in terms of the Faraday 2-form F and using the decomposition of F in terms of the electric and magnetic fields as four-dimensional (4D) geometric quantities. It is shown that there is a static electric field outside a stationary solenoid with resistive conductor carrying steady current, which causes that the AB phase difference in the magnetic AB effect may be determined by the electric part of the covariant expression, i.e. by the local influence of the 4D electric field and not, as generally accepted,in terms of nonzero vector potential.

One-dimensional Dirac electrons on the surface of weak topological insulators

description: We show that a class of weak three-dimensional topological insulators feature one-dimensional Dirac electrons on their surfaces. Their hallmark is a line-like energy dispersion along certain directions of the surface Brillouin zone. These one-dimensional Dirac line degeneracies are topologically protected by a symmetry that we refer to as in-plane time-reversal invariance. We show how this invariance leads to Dirac lines in the surface spectrum of stacked Kane-Mele systems and more general models for weak three-dimensional topological insulators.

title: Irrenanstalten und Geisteskrankheiten in der österreichischen Literatur des 20. Jahrhunderts unter besonderer Bezugnahme auf die Nervenheilanstalt "Am Steinhof"
Creators: name: Schütz, Benedikta
Year: 2021

description: Die vorliegende Arbeit analysiert mit Hilfe der literaturwissenschaftlichen Methode der historischen Diskursanalyse nach Foucault, in welcher Weise das „Verrücktwerden“ und der „Wahnsinn“ in ausgewählten Werken der Autoren Joseph Roth und Thomas Bernhard literarisch verarbeitet werden. Die politischen Erfahrungen beider Autoren machen sich in ihren Beurteilungen bemerkbar: Während Roth den Untergang der Donaumonarchie als Ursache für den Übergang in den „Wahnsinn“ versteht, vermutet Bernhard die Verdrängung des Nazionalsozialismus als Auslöser des „Verrücktwerdens“. Beide Autoren sind bestrebt Normalität und Wahnsinn nicht als Gegensatz voneinander wahrzunehmen, sondern weisen vielmehr auf die Gemeinsamkeiten zwischen Gesunden und Kranken hin. Gleichzeitig untersucht die Arbeit, welche Rolle und Funktion der Nervenheilanstalt „Am Steinhof“ in den Werken Roths und Bernhards zugeschrieben wird. In ihrer Kritik an der Antipsychatrie, wird sie einerseits als Rückzugsort für hellsichtige Menschen, andererseits als Verwahrungslager für die, an der Welt gescheiteten Figuren, beschrieben.
title: Mutter-Kind-Verhaltenssynchronisation und sensomotorische Kontingenzverletzung
Creators: name: Ibrahim, Fatima
Year: 2021

description: Die vorliegende Masterarbeit beschäftigt sich mit der Thematik der Kontingenzen. Es existieren zahlreiche Studien zum Thema der Kontingenzen, allerdings gibt es nur wenige, die sich mit dem Transfereffekt von sozialer zu nicht-sozialer Domäne beschäftigt haben. Daher wurde in dieser Arbeit die Fragestellung untersucht, ob Verhaltenssynchronisation in der sozialen Domäne die Erwartungen von Kindern hinsichtlich sensomotorischer Kontingenzen vorhersagen würde. Konkret lautete die Hypothese, dass Kinder aus Mutter-Kind-Dyaden mit hoher Verhaltenssynchronisation eine stärkere Reaktion auf eine physikalische Kontingenzverletzung zeigen würden. Kinder aus Mutter-Kind-Dyaden mit hoher Verhaltenssynchronisation sollten demnach stärker auf eine manipulierte Rassel reagieren, indem sie diese häufiger oder länger schütteln bzw. schlagen würden. Dafür wurden Videoaufnahmen aus einem aktuell laufenden Projekt (coSMIC) verwendet. Mithilfe des Medians wurden zwei Gruppen (niedrige und hohe Verhaltenssynchronisation) erstellt. Für die statistische Analyse kam der t-Test für unabhängige Stichproben zur Anwendung, bei dem 36 Mutter-Kind-Dyaden analysiert wurden. Die Ergebnisse dieser Studie konnten die Hypothese nicht bestätigen. Zwar zeigte sich ein Unterschied zwischen der Gruppe mit niedriger und der Gruppe mit hoher Verhaltenssynchronisation, allerdings war dieser Unterschied statistisch nicht signifikant nachweisbar. Mögliche Erklärungen dafür werden im Diskussionsteil behandelt.

description: Most introductory quantum physics instructors would agree that transitioning students from classical to quantum thinking is an important learning goal, but may disagree on whether or how this can be accomplished. Although (and perhaps because) physicists have long debated the physical interpretation of quantum theory, many instructors choose to avoid emphasizing interpretive themes; or they discuss the views of scientists in their classrooms, but do not adequately attend to student interpretations. In this synthesis and extension of prior work, we demonstrate: (1) instructors vary in their approaches to teaching interpretive themes; (2) different instructional approaches have differential impacts on student thinking; and (3) when student interpretations go unattended, they often develop their own (sometimes scientifically undesirable) views. We introduce here a new modern physics curriculum that explicitly attends to student interpretations, and provide evidence-based arguments that doing so helps them to develop more consistent interpretations of quantum phenomena, more sophisticated views of uncertainty, and greater interest in quantum physics.

description: The MiniBooNE experiment has reported results from the analysis of $ν_e$ and $\bar ν_e$ appearance searches, which show an excess of signal-like events at low reconstructed neutrino energies, with respect to the expected background. A significant component of this background comes from photon emission induced by (anti)neutrino neutral current interactions with nucleons and nuclei. With an improved microscopic model for these reactions, we predict the number and distributions of photon events at the MiniBooNE detector. Our results are compared to the MiniBooNE in situ estimate and to other theoretical approaches. We find that, according to our model, neutral current photon emission from single-nucleon currents is insufficient to explain the events excess observed by MiniBooNE in both neutrino and antineutrino modes.

Six observations consistent with the electron neutrino being a tachyon with mass: $m_{ν_e}^2=-0.11 \pm 0.016 eV^2$

description: Six observations based on data and fits to data from a variety of areas are consistent with the hypothesis that the electron neutrino is a $m_{ν_e}^2 = -0.11 \pm 0.016 eV^2$ tachyon. The data are from areas including CMB fluctuations, gravitational lensing, cosmic ray spectra, neutrino oscillations, and $0ν$ double beta decay. For each of the six observations it is possible under explicitly stated assumptions to compute a value for $m_{ν_e}^2,$ and it is found that the six values are remarkably consistent with the above cited $ν_e$ mass $(χ^2=2.73).$ There are no known observations in clear conflict with the claimed result. Three checks are proposed to test the validity of the claim, one of which could be performed using existing data.

description: While most topic modeling algorithms model text corpora with unigrams, human interpretation often relies on inherent grouping of terms into phrases. As such, we consider the problem of discovering topical phrases of mixed lengths. Existing work either performs post processing to the inference results of unigram-based topic models, or utilizes complex n-gram-discovery topic models. These methods generally produce low-quality topical phrases or suffer from poor scalability on even moderately-sized datasets. We propose a different approach that is both computationally efficient and effective. Our solution combines a novel phrase mining framework to segment a document into single and multi-word phrases, and a new topic model that operates on the induced document partition. Our approach discovers high quality topical phrases with negligible extra cost to the bag-of-words topic model in a variety of datasets including research publication titles, abstracts, reviews, and news articles.

description: In this paper we evolve magnetized and unmagnetized circumbinary accretion disks around supermassive black hole binaries in the relativistic regime. We use a post-Newtonian expansion to construct an analytical spacetime and determine how the order of the post-Newtonian (PN) expansion affects the dynamics of the gas. We find very small differences in the late-time bulk dynamics of non-magnetized hydrodynamic evolutions between the two spacetimes down to separations of approximately $40GM/c^2$ where $M$ is the total mass of the binary. For smaller separations, the differences due to PN-order become comparable to differences caused by using initial data further from equilibrium. For magnetized gas, MHD stresses, which drives the accretion dynamics, tends to mask all higher order PN effects even at separations of $20GM/c^2$, leading to essentially the same observed electromagnetic luminosity. This implies that our calculations of the EM signal may be robust down to small binary separations. Our investigation is the first to demonstrate how the level of PN accuracy affects a circumbinary disk's evolution and informs us of the range in separation within which to trust the PN approximation for this kind of study. We also address the influence the initial conditions and binary separation have on simulation predictions.

Measurement of differential production cross-sections for a $Z$ boson in association with $b$-jets in 7 TeV proton-proton collisions with the ATLAS detector

description: Measurements of differential production cross-sections of a $Z$ boson in association with $b$-jets in $pp$ collisions at $\sqrt{s}=7$ TeV are reported. The data analysed correspond to an integrated luminosity of 4.6 fb$^{-1}$ recorded with the ATLAS detector at the Large Hadron Collider. Particle-level cross-sections are determined for events with a $Z$ boson decaying into an electron or muon pair, and containing $b$-jets. For events with at least one $b$-jet, the cross-section is presented as a function of the $Z$ boson transverse momentum and rapidity, together with the inclusive $b$-jet cross-section as a function of $b$-jet transverse momentum, rapidity and angular separations between the $b$-jet and the $Z$ boson. For events with at least two $b$-jets, the cross-section is determined as a function of the invariant mass and angular separation of the two highest transverse momentum $b$-jets, and as a function of the $Z$ boson transverse momentum and rapidity. Results are compared to leading-order and next-to-leading-order perturbative QCD calculations.

description: A continuous-variable measurement-device-independent quantum key distribution (CV-MDI QKD) protocol using squeezed states is proposed where the two legitimate partners send Gaussian-modulated squeezed states to an untrusted third party to realize the measurement. Security analysis shows that the protocol can not only defend all detector side channels, but also attain higher secret key rates than the coherent-state-based protocol. We also present a method to improve the squeezed-state CV-MDI QKD protocol by adding proper Gaussian noise to the reconciliation side. It is found that there is an optimal added noise to optimize the performance of the protocol in terms of both key rates and maximal transmission distances. The resulting protocol shows the potential of long-distance secure communication using the CV-MDI QKD protocol.

description: We compute the contribution of phonons to the thermal conductivity in the core of superfluid neutron stars. We use effective field theory techniques to extract the phonon scattering rates, written as a function of the equation of state of the system. We also calculate the phonon dispersion law beyond linear order, which depends on the gap of superfluid neutron matter. With all these ingredients, we solve the Boltzmann equation numerically using a variational approach. We find that the thermal conductivity $κ$ is dominated by combined small and large angle binary collisions. As in the color-flavor-locked superfluid, we find that our result can be well approximated by $κ\propto 1/ Δ^6$, where $Δ$ is the neutron gap, the constant of proportionality depending on the density. We further comment on the possible relevance of electron and superfluid phonon collisions in obtaining the total contribution to the thermal conductivity in the core of superfluid neutron stars.

description: Cloud computing had become the new paradigm of the future, as it is the most widely used of all the technologies which are available, allowing consumers to readily maneuver their innovative digital demands. In this study, it is revealed that consumers’ expectations are more inclined towards data security and challenges associated with it but, data storage location was not found too much of importance in consumers mind. Furthermore, terms of service agreement between consumer and cloud service provider with declaration of rights was found to be having an anchoring effect on consumer loyalty. This security level perception in consumers mind was a raised due threat created by cyber hackers, data leaks, data misuse and extortion that frequently happened now and then, these events had spurred negative security and threat perception in minds of consumers. The sample size used in the study for consumer survey is 147. The sample unit consist of consumers and employees working on cloud platforms, regular users of cloud services. Consumers are however expecting a robust security measures with more security practices and also expect more clarity in service agreements terms and conditions, as it clear from our study that 32.3% consumers tend to read those lengthy instruction manuals and also those long cloud service providers service agreements, due to which they end up with correct choices. Results confirms that addressing diverse consumer’s expectation towards security challenges positively influences consumer’s loyalty.
Convergence of discrete time Kalman filter estimate to continuous time estimate

description: This article is concerned with the convergence of the state estimate obtained from the discrete time Kalman filter to the continuous time estimate as the temporal discretization is refined. We derive convergence rate estimates for different systems, first finite dimensional and then infinite dimensional with bounded or unbounded observation operators. Finally, we derive the convergence rate in the case where the system dynamics is governed by an analytic semigroup. The proofs are based on applying the discrete time Kalman filter on a dense numerable subset of a certain time interval $[0,T]$.

description: We characterize the Mott insulating regime of a repulsively interacting Fermi gas of ultracold atoms in a three-dimensional optical lattice. We use in-situ imaging to extract the central density of the gas, and to determine its local compressibility. For intermediate to strong interactions, we observe the emergence of a plateau in the density as a function of atom number, and a reduction of the compressibility at a density of one atom per site, indicating the formation of a Mott insulator. Comparisons to state-of-the-art numerical simulations of the Hubbard model over a wide range of interactions reveal that the temperature of the gas is of the order of, or below, the tunneling energy scale. Our results hold great promise for the exploration of many-body phenomena with ultracold atoms, where the local compressibility can be a useful tool to detect signatures of different phases or phase boundaries at specific values of the filling.

description: Among the main causes of the current crisis, there is certainly a lackof adequate criteria to measure economic value, and this is linked tothe way official currency value is designed, imbued with intrinsic andanonymous economic value. Official currencies perform their functionof economic accounting only because they offer a general equivalent ofall value (Marx), i.e. because they have an abstract and internalvalue, but this prevents them from being effective instruments ofeconomic measure, making them unstable and relatively inexpressive ofany concrete value.Despite its importance in the current systemic crisis, the lack ofinstruments for measuring economic value has not warranted specialattention in prevailing alternative currency schemes. This is partlyrelated to a prevalence of approaches that limit attention to thesocial integration functions of alternative currencies and/or theexchange functions for reviving economic growth and full employment ofresources. However, in order to restore the wider emancipativepotential of alternative currencies and better address the currentsystemic crisis, we have to reconsider the economic measure problemsmainly from the viewpoint of the links between human activities andthe common conditions of existence, or life contexts, in which theflow of time has a fundamental influence.

description: Probabilistic automata constitute a versatile and elegant model for concurrent probabilistic systems. They are equipped with a compositional theory supporting abstraction, enabled by weak probabilistic bisimulation serving as the reference notion for summarising the effect of abstraction. This paper considers probabilistic automata augmented with costs. It extends the notions of weak transitions in probabilistic automata in such a way that the costs incurred along a weak transition are captured. This gives rise to cost-preserving and cost-bounding variations of weak probabilistic bisimilarity, for which we establish compositionality properties with respect to parallel composition. Furthermore, polynomial-time decision algorithms are proposed, that can be effectively used to compute reward-bounding abstractions of Markov decision processes in a compositional manner.
