description: A search for duplicity of lambda Bootis stars has been made by using the speckle camera installed at the Telescopio Nazionale Galileo. The operation mode and the reduction procedure allow one to obtain not only the separation, but also the magnitude difference between the components; the latter parameter is fundamental for determining the degree of contamination from the secondary component of a binary system and thus the importance of the veiling effect that produces absorption lines weaker than normal. Two stars, HD 38545 and HD 290492, are close binaries with values of the separation and of the magnitude difference such that only a composite spectrum can be observed. For another 15 lambda Bootis candidates, observed with negative results, the upper limits of a possible companion separation are given.

Graph test of controllability in qubit arrays: a systematic way to determine the minimum number of external controls

description: The ability to implement any desired quantum logic gate on a quantum processing unit is equivalent to evolution-operator controllability of the qubits. Conversely, controllability analysis can be used to minimize the resources, i.e. the number of external controls and qubit–qubit couplings, required for universal quantum computing. Standard controllability analysis, consisting in the construction of the dynamical Lie algebra, is, however, impractical already for a comparatively small number of qubits. Here, we show how to leverage an alternative approach, based on a graph representation of the Hamiltonian, to determine controllability of arrays of coupled qubits. We provide a complete computational framework and exemplify it for arrays of five qubits, inspired by the ibmq_quito architecture. We find that the number of controls can be reduced from five to one for complex qubit–qubit couplings and to two for standard qubit–qubit couplings.

description: Lower Ordovician brachiopod macrofaunas in Belgium (Avalonia) are seldom collected and studied due to the poor preservation of material. Here we describe a new fauna of linguliformean brachiopods from the Chevlipont Formation (lower Tremadocian) in the Brabant Massif. The fauna is of low diversity (at least three species belonging to Rosobolus?, Thysanotos, and Broeggeria have been identified) and is dominated by B. cf. salteri (Holl). Low diversity linguliformean brachiopod assemblages in a peri-Gondwanan terrane are characteristic of the lowermost Ordovician. Such assemblages are rooted in the Cambrian indicating that their geographic distribution during the early Ordovician was controlled by the radiation and dispersion of lineages surviving through the latest Cambrian–earliest Tremadocian linguliformean brachiopods taxonomic crisis. In addition we figure for the first time and comment on contemporaneous brachiopod faunas from the Stavelot-Venn Massif in SE Belgium. Finally, we present new graptolite data that enable a more precise constraint on the age for the Solwaster Member of the Jalhay Formation in the Stavelot-Venn Massif.

description: The physics behind the origin and composition of the Cosmic Microwave Background (CMB) is a well-established topic in the field of Cosmology. Literature on CMB anisotropies reveal consistency with Gaussianity, but these were conducted on full multi-frequency temperature maps. In this thesis, we utilise clustering algorithms to specifically conduct statistical analyses on the distribution of hotspots in the CMB. We describe a series of data processing and clustering methodologies conducted, with results that conclusively show that the counts-in-cells distribution of hotspots in the CMB does not follow a Poisson distribution. Rather, the distribution exhibits a much closer fit to both the Negative Binomial Distribution (NBD) and the Gravitational Quasi-Equilibrium Distribution (GQED). From this result, we conclude that structure likely existed in the early universe, from the period of the recombination Epoch, possibly opening new insights in the field of galaxy formation.

description: Daniel Glattauer’s novel Gut gegen Nordwind (2006), English translation: Love virtually (2011) is the first email-novel of German literature. The love triangle between Leo Leike, Emma and Bernhard Rothner is narrated through 785 emails. Their “computer mediated communication” gives birth to a virtual world that is separated from their ordinary lives. This virtual dimension becomes the projection screen for their identities, bodily representations and desires. It also becomes their cage as they will never meet in reality.

description: We present 13 Broad Absorption Line (BAL) quasars, including 12 new objects, which were identified in the Sloan Digital Sky Survey (SDSS) and matched within 2'' to sources in the FIRST radio survey catalog. The surface density of this sample of radio-detected BAL quasars is 4.5 +- 1.2 per 100 deg^2, i.e. approximately 4 times larger than previously found by the shallower FIRST Bright Quasar Survey (FBQS). A majority of these radio-detected BAL quasars are moderately radio-loud objects. The fraction of BAL quasars in the entire radio quasar sample, 4.8 +- 1.3 %, is comparable to the fraction of BAL quasars among the SDSS optical quasar sample (ignoring selection effects). We estimate that the true fraction of BAL quasars (mostly HiBALs) in the radio sample is 9.2 +- 2.6 % once selection effects are accounted for. We caution that the absorption troughs of 4 of the 13 radio-detected quasars considered do not strictly satisfy the standard BALnicity criterion. One or possibly two of the new radio-detected BAL quasars are of the rare ``iron LoBAL'' type. BAL quasars are generally redder than the median SDSS quasar at the same redshift.

Wir bringen heute den ersten Teil des 90-minütigen Beitrags. Der zweite folgt am 5. Februar 2025 in diesem Programm um 17:00. Mal schnell Geld verdienen, zuhause, mit dem Handy oder dem Tablet – wenn es sein muss einen fünfstelligen Eurobetrag im Monat? Selbständig arbeiten und im Luxus leben? Genau das verspricht iGenuis seinen Mitgliedern. Im Netz werben viele Influencer*innen für diese Plattform. Firmen wie iGenius operieren mit Multi-Level-Marketing, kurz MLM, in einer Art Schneeballsystem. Sie rekrutieren dabei neue Mitglieder, verlangen hohe Startgebühren für die Mitgliedschaft oder drängen ihre Mitglieder dazu, Produkte zu kaufen, die sie im Zweifel nicht weiterverkaufen können. Eine Kernproblematik, die sowohl für Schneeballsysteme, als auch für legal operierende MLM-Systeme gilt, ist die Täuschung von Mitgliedern oder Interessent*innen. Im Mittelpunkt steht die von den sogenannten Vertrieblern verbreitete Annahme, sich mithilfe der Firma ein hohes passives Einkommen aufbauen zu können. Multi-Level-Marketing arbeitet auch mit falschen oder übertriebenen Versprechen und weniger mit dem Ziel, die entsprechenden Produkte zu bewerben. Mit im Spiel ist meistens auch das berüchtigte Pyramidenmodell. Die beiden Wirtschaftswissenschaftler*innen Claudia Groß und Dirk Vriens von der Universität Radboud in den Niederlanden haben 2017 nachgewiesen, dass bei einem Unternehmenswachstum durch exponentielle Rekrutierung das Einkommen sehr ungleichmäßig verteilt ist. Lediglich jene Mitglieder, die zu Beginn ins Unternehmen eingestiegen sind, verdienen viel Geld. Die Nachzügler*innen gehen meist leer aus. Irina Lazareva hat in ihrem investigativen Feature das Geschäftsmodell von iGenius untersucht und auch mit einem Aussteiger gesprochen.

description: We consider the ensemble Kalman inversion (EKI) which has been recently introduced as an efficient, gradient-free optimisation method to estimate unknown parameters in an inverse setting. In the case of large data sets, the EKI becomes computationally infeasible as the data misfit needs to be evaluated for each particle in each iteration. Here, randomised algorithms like stochastic gradient descent have been demonstrated to successfully overcome this issue by using only a random subset of the data in each iteration, so-called subsampling techniques. Based on a recent analysis of a continuous-time representation of stochastic gradient methods, we propose, analyse, and apply subsampling-techniques within EKI. Indeed, we propose two different subsampling techniques: either every particle observes the same data subset (single subsampling) or every particle observes a different data subset (batch subsampling).
Density of Neutral Solitons in Weakly Disordered Peierls Chains

description: We study the effects of weak off-diagonal disorder on Peierls systems with a doubly degenerate ground state. We show that for these systems disorder in the electron hopping amplitudes induces a finite density of solitons in the minimal-energy lattice configuration of a single chain. These disorder-induced dimerization kinks are neutral and have spin 1/2. Using a continuum model for the Peierls chain and treating the lattice classically, we analytically calculate the average free energy and density of kinks. We compare these results to numerical calculations for a discrete model and discuss the implications of the kinks for the optical and magnetic properties of the conjugated polymer trans-polyacetylene.

Reitergeschichten. Gaito Gasdanow und das Phantom des Hugo von Hofmannsthal
Creators: name: Apostolo, Stefano

Year: 2021

description: In 1947 the Russian writer Gaito Gasdanow published The Spectre of Alexander Wolf, a novel that appears to mirror various aspects of Hugo von Hofmannsthal’s Reitergeschichte [A Cavalry Tale] (1899). Although at present it cannot be philologically proved that the Reitergeschichte directly inspired Gasdanow, several striking parallels can be drawn between the two works, such as the way the themes of war and revolution are addressed, the encounter with doppelgängers, their deaths, and how the capture of the horse ultimately deals the fatal blow to both protagonists. This article examines these aspects closely by contextualizing them within the literary output and the biographies of both authors.

description: Relaxations at nonpolar surfaces of III-V compounds result from a competition between dehybridization and charge transfer. First principles calculations for the (110) and (10$\bar{1}$0) faces of zincblende and wurtzite AlN, GaN and InN reveal an anomalous behavior as compared with ordinary III-V semiconductors. Additional calculations for GaAs and ZnO suggest close analogies with the latter. We interpret our results in terms of the larger ionicity (charge asymmetry) and bonding strength (cohesive energy) in the nitrides with respect to other III-V compounds, both essentially due to the strong valence potential and absence of $p$ core states in the lighter anion. The same interpretation applies to Zn II-VI compounds.

description: The Shor–Laflamme distribution (SLD) of a quantum state is a collection of local unitary invariants that quantify k-body correlations. We show that the SLD of graph states can be derived by solving a graph-theoretical problem. In this way, the mean and variance of the SLD are obtained as simple functions of efficiently computable graph properties. Furthermore, this formulation enables us to derive closed expressions of SLDs for some graph state families. For cluster states, we observe that the SLD is very similar to a binomial distribution, and we argue that this property is typical for graph states in general. Finally, we derive an SLD-based entanglement criterion from the purity criterion and apply it to derive meaningful noise thresholds for entanglement. Our new entanglement criterion is easy to use and also applies to the case of higher-dimensional qudits. In the bigger picture, our results foster the understanding both of quantum error-correcting codes, where a closely related notion of SLDs plays an important role, and of the geometry of quantum states, where SLDs are known as sector length distributions.

description: Spin-orbit coupling is a fundamental mechanism that connects the spin of a charge carrier with its momentum. Likewise, in the optical domain, a synthetic spin-orbit coupling is accessible, for instance, by engineering optical anisotropies in photonic materials. Both, akin, yield the possibility to create devices directly harnessing spin- and polarization as information carriers. Atomically thin layers of transition metal dichalcogenides provide a new material platform which promises intrinsic spin-valley Hall features both for free carriers, two-particle excitations (excitons), as well as for photons. In such materials, the spin of an exciton is closely linked to the high-symmetry point in reciprocal space it emerges from. Here, we demonstrate, that spin, and hence valley selective propagation is accessible in an atomically thin layer of MoSe2, which is strongly coupled to a microcavity photon mode. We engineer a wire-like device, where we can clearly trace the flow, and the helicity of exciton-polaritons expanding along a channel. By exciting a coherent superposition of K and K- tagged polaritons, we observe valley selective expansion of the polariton cloud without neither any applied external magnetic fields nor coherent Rayleigh scattering. Unlike the valley Hall effect for TMDC excitons, the observed optical valley Hall effect (OVHE) strikingly occurs on a macroscopic scale, and clearly reveals the potential for applications in spin-valley locked photonic devices.
Isotropic Transverse XY Chain with Energy- and Magnetization Currents

description: The ground-state correlations are investigated for an isotropic transverse XY chain which is constrained to carry either a current of magnetization J_M or a current of energy J_E. We find that the effect of nonzero J_M on the large-distance decay of correlations is twofold: i) oscillations are introduced and ii) the amplitude of the power law decay increases with increasing current. The effect of energy current is more complex. Generically, correlations in current carrying states are found to decay faster than in the J_E=0 states, contrary to expectations that correlations are increased by the presence of currents. However, increasing the current, one reaches a special line where the correlations become comparable to those of the J_E=0 states. On this line, the symmetry of the ground state is enhanced and the transverse magnetization vanishes. Further increase of the current destroys the extra symmetry but the transverse magnetization remains at the high-symmetry, zero value.

description: This study develops a framework and analytical model based on life-cycle assessment (LCA) for NextEnergy to evaluate the environmental and energy life cycle performance of its Microgrid Pavilion (hereafter "the microgrid"). Life cycle assessment is an analytical tool based on ISO 14040 standards that characterize the full energy and environmental consequences of a product or service system. A key aspect of the LCA for this study is the inclusion of upstream or pre-combustion processes in energy modeling. The energy and emissions resulting from all processes before a fuel is combusted or converted to electricity or heat energy (e.g. extraction, reformation, delivery) are modeled in the report.

description: We report results of molecular-dynamics simulations for a glassy polymer melt consisting of short, linear bead-spring chains. It was shown in previous work that this onset of the glassy slowing down is compatible with the predictions of the mode coupling theory. The physical process of `caging' of a monomer by its spatial neighbors leads to a distinct two step behavior in the particle mean square displacements. In this work we analyze the effects of this caging process on the Rouse description of the melt's dynamics. We show that the Rouse theory is applicable for length and time scales above the typical scales for the caging process. Futhermore, the monomer displacement is compared with simulation results for a binary Lennard-Jones mixture to point out the differences which are introduced by the connectivity of the particles.

description: In this work, we investigate the practice of patch construction in the Linux kernel development, focusing on the differences between three patching processes: (1) patches crafted entirely manually to fix bugs, (2) those that are derived from warnings of bug detection tools, and (3) those that are automatically generated based on fix patterns. With this study, we provide to the research community concrete insights on the practice of patching as well as how the development community is currently embracing research and commercial patching tools to improve productivity in repair. The result of our study shows that tool-supported patches are increasingly adopted by the developer community while manually-written patches are accepted more quickly. Patch application tools enable developers to remain committed to contributing patches to the code base. Our findings also include that, in actual development processes, patches generally implement several change operations spread over the code, even for patches fixing warnings by bug detection tools. Finally, this study has shown that there is an opportunity to directly leverage the output of bug detection tools to readily generate patches that are appropriate for fixing the problem, and that are consistent with manually-written patches.
Wien als Blickgewebe. Überlegungen zu Veza Canettis «Die Gelbe Straße»
Creators: name: Vinardell Puig, Teresa
Publisher: name: Studia austriaca
Year: 2021

description: The following article is focused on the importance of visual perception in Veza Canetti’s Die Gelbe Straße. The novelist portraits a Viennese microcosmos as a fabric in which glances are tightly interwoven, representing an urban way of life that, due to its complexity, demands sharp attention and cunning strategic behaviour from everybody. Canetti aims to challenge all the clichés which praised Vienna as an anti-modern, idyllic capital city, characterizing it as deeply rooted in history and art, and thus more humane. Her novel opposes this idealized vision of her hometown by revealing the pitiless nature of its inhabitants. The multiple ways of looking which may be detected on one street mostly reflect different forms of exerting power in society.

Spaces of Contrast. A Spatial Analysis of Franz Grillparzer’s «Der arme Spielmann»
Creators: name: Jiang, Xiaohu
Publisher: name: Studia austriaca
Year: 2021

description: Physical setting plays an important role in literary writings. After the spatial turn, scholars of literary studies also turned their eyes to the sociological significance of spatial description in literary texts. This essay presents a spatial analysis of Grillparzer’s Der arme Spielmann and argues that in this novella Grillparzer uses the contrast in space as a vital indicator of the disparity between his characters. These spatial contrasts are mainly derived from characters’ differences in terms of birth, class, wealth, education, job and so on. The difficulty of reducing those differences signifies the suffocating political atmosphere in nineteenth-century Austria.

Crosstalk between long non-coding RNAs and circadian chromatin
Creators: name: Zhu, Qiaoqiao
Publisher: name: No Publisher Supplied
Year: 2020

description: The circadian rhythm is governed by transcriptional negative feedback facilitated by oscillating histone modifications and chromatin remodeling. The circadian rhythm is entrained by external zeitgebers (light and temperature) and are conserved in Neurospora, Drosophila, zebrafish, and mammals. The clock gene frequency in Neurospora and Period2 in vertebrates have natural antisense transcripts (NATs) whose function is not understood. In this dissertation I examined the connection among the circadian clock, non-coding RNAs and heterochromatin formation on both on the genome-wide and locus-specific level using a multi-organism approach. I performed a genome-wide study, using RNA-seq and ChIP-seq to understand the role of H3 lysine 4 methyltransferase (KMT2/SET-1) and histone H3 lysine 9 methyltransferase (KMT1/DIM-5) in Neurospora to understand the role of 2 seemingly opposing modifications. Integrated analysis of RNA-seq and ChIP-seq showed crosstalk and redistributions between histone H3 lysine 4 tri-methylation (H3K4me3) and histone H3 lysine 9 tri-methylation (H3K9me3). I also examined how perturbing the expression of a diurnal lncRNA affected downstream heterochromatin formation at the telomeres. The core circadian clock controls rhythms in TERRA, a long noncoding RNA that originates from telomeres and my research shows alcohol disrupts the diurnal rhythm in TERRA and heterochromatin at the telomere, which in theory makes telomeres more susceptible to DNA damage. I also examined the Per2 NAT, Per2AS and found the diurnal rhythm in Per2AS is dependent on BMAL1. Using the ChIRP-MS, I identified Per2AS-interacting proteins. Specifically, I found hnRNP M interacts with Per2AS and hnRNP M is required to maintain the normal amplitude and period of Per2. Furthermore, I demonstrate that hnRNP M is necessary for H3K9me3 and H3K27me3 at Per2. These findings support a model where Per2AS may serve as scaffold for hnRNP M and other associated proteins that assist in heterochromatin formation at Per2. Collectively, this dissertation furthers our understanding of the circadian clock, non-coding RNAs, and circadian regulated facultative heterochromatin formation.

description: Using traversable wormholes as theoretical background, we revisit a deep question of general relativity: Does a uniformly accelerated charged particle radiate? We particularize to the recently proposed gravitational Čerenkov radiation, that happens when the spatial part of the Ricci tensor is negative. If $^{^{(3+1)}}R^i_{\phantom{i}i}< 0$, the matter threading the gravitational field violates the weak energy condition. In this case, the effective refractive index for light is bigger than 1, i.e. particles propagates, in that medium, faster than photons. This leads to a violation of the equivalence principle.

Wiener vs. Berliner Moderne. Die kompetitive “Dichterfreundschaft” zwischen Arthur Schnitzler und Richard Dehmel
Creators: name: Ilgner, Julia

description: The following article reconstructs the almost 25-year-long relationship between the two fin de siècle poets Arthur Schnitzler and Richard Dehmel. The analysis is based on the assumption that the rival “artist friendship” is determined by a constitutive generic competition. Schnitzler admired Dehmel’s genius in forms of poetry that he himself had not mastered, first and foremost lyric poetry, but otherwise regarded him critically where he himself had succeeded, namely in the genre of drama. This early resentment forms a lifelong paradigm of Schnitzler’s perception of Dehmel and prevented a sincere appreciation of Dehmel as an artistic equal.

description: We consider Dirac fermions interacting with a disordered non-Abelian vector potential. The exact solution is obtained through a special type of conformal field theory including logarithmic correlators, without resorting to the replica or supersymmetry approaches. It is shown that the proper treatment of the conformal theory leads to a different multifractal scaling behaviour than initially expected. Moreover, the previous replica solution is found to be incorrect at the level of higher correlation functions.

description: The dynamics of the $J^{PC}=0^{-+}$, $0^{++}$, and $2^{++}$ resonance contributions to the decay $J/ψ\toγX(J^{PC})\toγϕϕ$ is analysed using the data obtained by BESIII collaboration. The effective coupling constants parameterising invariant amplitudes of the transitions $J/ψ\toγX(J^{PC})$ and $X(J^{PC})\toϕϕ$ and masses of $X(J^{PC})$ resonances are found from the fits. They are used for evaluation of the branching fractions $B_{X(J^{PC})\toϕϕ}$, relative branching fractions $B_{J/ψ\toγX(J^{PC})\toγϕϕ}$, and for obtaining the photon angular distributions.

Magnetic Field Effect in Josephson tunneling between d-Wave Superconductors

description: The magnetic field effect in the Josephson tunneling between two d-wave superconductors are investigated. When the crystal orientation of one (or each) superconductor relative to the interface normal is such that midgap states exist at the interface, there is a component of the tunneling current due to the midgap states. For a junction with a flat {001}|{110} or {100}|{110} interface, this component is the predominant contribution to the current. The predicted current-field dependence differs entirely from the conventional Fraunhofer pattern, in agreement with a published measurement. This is because, apart from the Fraunhofer factor, the critical current depends on the magnetic field B through the current density also which is a linear function of B for weak B.

Constraints on the nuclear emission from the Circinus galaxy: the torus

description: In the context of the unified model of Seyfert galaxies, we use observations from the literature and a radiative transfer model to investigate the near-IR to mm emission produced by the presumed torus in the Circinus galaxy, from 2microns to 1.3mm. From the infrared SED modelling, we find that the total luminosity (L_{IR}) in this wavelength range, consists of similar contributions from the torus and starburst with a ratio of nuclear luminosity to starburst luminosity (L_{NUC}/L_{SB}) approx. 0.8. By using a similar torus model to that of NGC1068, but without the conical dust, we find an upper limit to the outer torus radius of approx. 12pc with a best fit of approx. 2pc. The upper limit torus size estimated from the radiative transfer modelling is consistent with the 16pc torus radius estimated from near-IR imaging polarimetry of Circinus.

description: The enigmatic coupling between electronic and magnetic phenomena was one of the riddles propelling the development of modern electromagnetism. Today, the fully controlled electric field evolution of ultrashort laser pulses permits the direct and ultrafast control of electronic properties of matter and is the cornerstone of light-wave electronics. In sharp contrast, because there is no first order interaction between light and spins, the magnetic properties of matter can only be affected indirectly on the much slower tens-of-femtosecond timescale in a sequence of optical excitation followed by the rearrangement of the spin structure. Here we record an orders of magnitude faster magnetic switching with sub-femtosecond response time by initiating optical excitations with near-single-cycle laser pulses in a ferromagnetic layer stack. The unfolding dynamics are tracked in real-time by a novel attosecond time-resolved magnetic circular dichroism (atto-MCD) detection scheme revealing optically induced spin and orbital momentum transfer (OISTR) in synchrony with light field driven charge relocation. In tandem with ab-initio quantum dynamical modelling, we show how this mechanism provides simultaneous control over electronic and magnetic properties that are at the heart of spintronic functionality. This first incarnation of attomagnetism observes light field coherent control of spin-dynamics in the initial non-dissipative temporal regime and paves the way towards coherent spintronic applications with Petahertz clock rates.

Testing velocity-dependent CPT-violating gravitational forces with radio pulsars

description: In the spirit of effective field theory, the Standard-Model Extension (SME) provides a comprehensive framework to systematically probe the possibility of Lorentz/CPT violation. In the pure gravity sector, operators with mass dimension larger than 4, while in general being advantageous to short-range experiments, are hard to investigate with systems of astronomical size. However, there is exception if the leading-order effects are CPT-violating and velocity-dependent. Here we study the lowest-order operators in the pure gravity sector that violate the CPT symmetry with carefully chosen relativistic binary pulsar systems. Applying the existing analytical results to the dynamics of a binary orbit, we put constraints on various coefficients for Lorentz/CPT violation with mass dimension 5. These constraints, being derived from the post-Newtonian dynamics for the first time, are complementary to those obtained from the kinematics in the propagation of gravitational waves.

The role of winding numbers in quantum Monte Carlo simulations

description: We discuss the effects of fixing the winding number in quantum Monte Carlo simulations. We present a simple geometrical argument as well as strong numerical evidence that one can obtain exact ground state results for periodic boundary conditions without changing the winding number. However, for very small systems the temperature has to be considerably lower than in simulations with fluctuating winding numbers. The relative deviation of a calculated observable from the exact ground state result typically scales as $T^γ$, where the exponent $γ$ is model and observable dependent and the prefactor decreases with increasing system size. Analytic results for a quantum rotor model further support our claim.

description: We report on three different and complementary measurements, namely magnetisation measurements, positron annihilation spectroscopy and NMR measurements, which give evidence that the formation of oxygen vacancy clusters is on the origin of the fishtail anomaly in YBa2Cu3O7-d. While in the case of YBa2Cu3O7.0 the anomaly is intrinsically absent, it can be suppressed in the optimally doped state where vacancies are present. We therefore conclude that the single vacancies or point defects can not be responsible for this anomaly but that clusters of oxygen vacancies are on its origin.
