title: Wortassoziationen: Ein interkultureller Vergleich zwischen dem Deutschen, dem Arabischen und dem Französischen
Creators: name: Ait Ramdan, Mohcine
Publisher: name: Universitäts- und Landesbibliothek Darmstadt
Year: 2023

description: Die kontrastive Semantik stellt nach wie vor erhebliche Unterschiede zwischen semantischen Merkmalen der Begriffe in verschiedenen Sprachen fest. Diese Unterschiede werden durch die lexikalische Oberfläche der Sprache nicht zum Vorschein gebracht. Mittels eines Wortassoziationsexperiments werden in dieser Untersuchung die konzeptuellen Unterschiede sowie Gemeinsamkeiten zwischen dem Deutschen, dem Arabischen und dem Französischen aufgezeigt. Das vorgestellte Experiment wurde mit 165 Arabisch-, Deutsch- und Französisch-Muttersprachlern durchgeführt. Die Probanden sollten ihre Erstreaktionen auf folgende drei Stimuli-Kategorien zeigen: 9 Adjektive, 11 Konkreta und 10 Abstrakta. Im Unterschied zu anderen psychotherapeutischen Studien, die hauptsächlich Konkreta untersuchten und keine kulturellen Differenzen aufdecken, wird in dieser Arbeit der Fokus besonders auf die Abstrakta gelegt. Um das Ausmaß der Kulturbedingtheit der Abstrakta ans Licht zu bringen, werden die hervorgerufenen Assoziationen der drei Stimuli miteinander verglichen. Die Annahme dabei ist, dass sich Abstrakta im Gegensatz zu Konkreta nicht mit sinnlich wahrnehmbaren Merkmalen beschreiben lassen und dadurch mehr Raum für kulturspezifische Interpretation aufweisen. Beispielhaft werden auch die beteiligten Metaphorisierungsprozesse von Abstrakta in den untersuchten Sprachen analysiert.
An efficient ionizer for an atomic beam of helium and a source of doubly charged helium ions.
Creators: name: Vermette, Clifford William Harvey
Publisher: name: University of British Columbia
Year: 2011

description: Part I An efficient ionizer designed for the ionization of a low intensity molecular beam has been developed. The ionizer will have an efficiency for an argon beam at room temperature and 0.8 amperes plate electron current of greater than 5.3% and for an helium 4 beam at room temperature and 0.8 amperes plate electron current of greater than 0.12%. The electron bombardment ionization occurs between two flat plates both of which are at 200 volts potential with respect to the cathode. The two plates are at a 2.5° angle to each other so that the ions once formed experience a field gradient produced by this angle which accelerates them out the open side of the ionizer 90° to the direction of the incident neutral beam. The electrons were emitted from 6, 0.030 x 0.004 inches, thoriated tungsten ribbon filaments heated by d.c. power. Successful activation of the filaments, however, was not achieved and so they were used as pure tungsten filaments. The ionizer ran at between 1900° Kelvin and 2600°Kelvin for about 8 hours without significant distortion, filament sag, or appreciable outgassing. Part II The design of a source of doubly charged helium ions was carried out to provide an helium beam of twice the terminal energy of the Van de Graafe Accelerator. The unit, to be installed in the top terminal of the Van de Graaffe, employs a radio frequency ion source followed by a double focusing magnet. The magnet has plane parallel pole pieces with a fringing field that produces focusing in a vertical plane. The unit is designed so that at 2.5 kilovolts extraction voltage a magnetic field of 3060 gauss is required to bend the He⁺⁺ through an angle of 90° and bring them to a focus at 5.8 cm. from the exit face of the magnet. The beam acceptance angle of the magnet is 10° at a source distance from the entrance face of 5 cm.

Mixing of t_{2g}-e_{g} orbitals in 4d and 5d transition metal oxides

description: Using exact diagonalization, we study the spin-orbit coupling and interaction-induced mixing between t2g and eg d-orbital states in a cubic crystalline environment, as commonly occurs in transition metal oxides. We make a direct comparison with the widely used t2g only or eg only model, depending on electronic ﬁlling. We consider all electron ﬁllings of the d-shell and compute the total magnetic moment, the spin, the occupancy of each orbital, and the eﬀective spin-orbit coupling strength (renormalized through interaction eﬀects) in terms of the bare interaction parameters, spin-orbit coupling, and crystal ﬁeld splitting, focusing on the parameter ranges relevant to 4d and 5d transition metal oxides. In various limits we provide perturbative results consistent with our numerical calculations. We ﬁnd that the t2g-eg mixing can be large, with up to 20% occupation of orbitals that are nominally “empty”, which has experimental implications for the interpretation of the branching ratio in experiments, and can impact the eﬀective local moment Hamiltonian used to study magnetic phases and magnetic excitations in transition metal oxides. Our results can aid the theoretical interpretation of experiments on these materials, which often fall in a regime of intermediate coupling with respect to electron-electron interactions.

Cross-correlations in scaling analyses of phase transitions
Creators: name: Weigel, Martin
name: Janke, Wolfhard
Publisher: name: arXiv
Year: 2008
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Thermal or finite-size scaling analyses of importance sampling Monte Carlo time series in the vicinity of phase transition points often combine different estimates for the same quantity, such as a critical exponent, with the intent to reduce statistical fluctuations. We point out that the origin of such estimates in the same time series results in often pronounced cross-correlations which are usually ignored even in high-precision studies, generically leading to significant underestimation of statistical fluctuations. We suggest to use a simple extension of the conventional analysis taking correlation effects into account, which leads to improved estimators with often substantially reduced statistical fluctuations at almost no extra cost in terms of computation time.

Creators: name: Johansson, Karmen Terlević
Publisher: name: Universitäts- und Landesbibliothek Darmstadt
Year: 2023

description: This article presents findings from an empirical study of oral production in German as a second foreign language (L3 German). It is based on the oral productions of 24 L1 Swedish pupils attending lower secondary school and compares the productions of CLIL learners to non-CLIL learners and German native speakers; its main objective is to investigate whether the CLIL approach has a positive impact on oral L3. The analyses focus on the size and frequency of the productive vocabulary as well as on the employment of communicative strategies.
Dynamic Monte Carlo radiation transfer in SPH. Radiation pressure force implementation

description: We present a new framework for radiation hydrodynamics simulations. Gas dynamics is modelled by the Smoothed Particle Hydrodynamics (SPH) method, whereas radiation transfer is simulated via a time-dependent Monte-Carlo approach that traces photon packets. As a first step in the development of the method, in this paper we consider the momentum transfer between radiation field and gas, which is important for systems where radiation pressure is high. There is no fundamental limitations on the number of radiation sources, geometry or the optical depth of the problems that can be studied with the method. However, as expected for any Monte-Carlo transfer scheme, stochastic noise presents a serious limitation. We present a number of tests that show that the errors of the method can be estimated accurately by considering Poisson noise fluctuations in the number of photon packets that SPH particles interact with per dynamical time. It is found that for a reasonable accuracy the momentum carried by photon packets must be much smaller than a typical momentum of SPH particles. We discuss numerical limitations of the code, and future steps that can be taken to improve performance and applicability of the method.

A D.C. amplifier and reference voltage supply suitable for use in a magnet current regulator
Creators: name: Edwards, Edward Murray
Publisher: name: University of British Columbia
Year: 2011

description: The requirements imposed upon a d.c. amplifier and reference voltage supply, suitable for measurement and control of signals of the order of 1 volt to an accuracy of 10 parts per million are investigated. A basic block design is proposed to achieve this goal using a transistor differential amplifier of new design and a highly regulated reference voltage supply. The detailed design procedure for these building blocks is then presented. Exact analysis of important characteristics of several relevant circuit configurations is presented. The unit under discussion was constructed and the measured performance was found to be in good agreement with the predicted performance.

description: We report significant transport critical currents firstly achieved in Sr0.6K0.4Fe2As2 wires and tapes with a Tc = 34 K, which were fabricated through an in-situ powder-in-tube process. Silver was used as a chemical addition as well as a sheath material. Transport measurements were performed by a standard four-probe resistive method. All the wire and tape samples have shown transport properties. Critical current density Jc was enhanced upon silver addition, and at 4.2 K, a best Jc of ~1200 A/cm^2 (Ic = 9 A) was achieved for 20 % silver added tapes, which is the highest in iron-based wires and tapes so far. The Jc is almost field independent between 1 T and 10 T, exhibiting a strong vortex pinning. Such a high transport critical current density is attributed to the absence of reaction layer between the silver sheath and superconducting core, as well as an improved connectivity between grains. We also identify a weak-link behavior from the creep drop of Jc at low fields and a hysteretic phenomenon. Finally, we found that compared to Fe, Ta and Nb tubes, Ag was the best sheath material for the fabrication of high-performance 122 type pnictide wires and tapes.

Extending the Theory of Time: Nonlocality and Memory Dynamics Inspired by Experimental Observations
Creators: name: Brown, Jesse
name: Fedotov, Anton
Publisher: name: Zenodo
Year: 2025

description: This work presents an extended theoretical framework for understanding the dynamics of time-dependent systems, integrating insights from recent experimental observations of nonlocal interactions and memory effects. By exploring phenomena such as reversed thermodynamic evolution and negative time delays in photon dynamics, the framework highlights the interplay between memory kernels and spatially distributed influences. The proposed mathematical models align qualitatively with experimental findings, offering new perspectives on time, energy landscapes, and probabilistic transitions. These insights pave the way for broader applications in cosmology, biology, and material science, positioning the theory as a unifying paradigm for studying complex, time-dependent behaviors.

Quantum gravity, gauge coupling constants, and the cosmological constant

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The quantization of Einstein-Maxwell theory with a cosmological constant is considered. We obtain all logarithmically divergent terms in the one-loop effective action that involve only the background electromagnetic field. This includes Lee-Wick type terms, as well as those responsible for the renormalization group behaviour of the electric charge (or fine structure constant). Of particular interest is the possible gauge condition dependence of the results, and we study this in some detail. We show that the traditional background-field method, that is equivalent to a more traditional Feynman diagram calculation, does result in gauge condition dependent results in general. One resolution of this is to use the Vilkovisky-DeWitt effective action method, and this is presented here. Quantum gravity is shown to lead to a contribution to the running charge not present when the cosmological constant vanishes. This re-opens the possibility, suggested by Robinson and Wilczek, of altering the scaling behaviour of gauge theories at high energies although our result differs. We show the possibility of an ultraviolet fixed point that is linked directly to the cosmological constant.

A new method for determining physical parameters of fundamental mode RR Lyrae stars from multicolour light curves

description: We present a new method for determining physical parameters of RRab variables exclusively from multicolour light curves. Our method is an Inverse Photometric Baade-Wesselink analysis which, using a nonlinear least squares algorithm, searches for the effective temperature (T_eff) and pulsational velocity (V_p) curves and other physical parameters that best fit the observed light curves, utilising synthetic colours and bolometric corrections from static atmosphere models. The T_eff and V_p curves are initially derived from empirical relations then they are varied by the fitting algorithm. The method yields the variations and the absolute values of the radius, the effective temperature, the visual brightness, and the luminosity of individual objects. Distance and mass are also determined. The method is tested on 9 RRab stars subjected to Baade-Wesselink analyses earlier by several authors. The physical parameters derived by our method using only the light curve data of these stars are well within their possible ranges defined by direct Baade-Wesselink and other techniques. A new empirical relation between the I_C magnitude and the pulsational velocity is also presented, which allows to construct the V_p curve of an RRab star purely from photometric observations to an accuracy of about 3.5 km/s.

description: At the Institute for Health Metrics and Evaluation, we conduct ~40 systematic reviews each year. In our general process to search > screen > extract > analyze, we found we need an intervening step: cleaning extracted data before analysis. The problem arises from a feature of our workflow: one person extracts the data, while another analyzes. Clean-up falls through the gap as we hand off data. Analysts must then spend time cleaning, though the extractor is far more familiar with the dataset. To work faster with fewer errors, we developed a stepwise cleaning checklist, then wrote code modules to fix common problems. But juggling Excel and R and a checklist still takes time and attention. To streamline further, we are developing a systematic solution: an interactive R-markdown notebook to take in parameters of the specific extraction dataset; clean and validate the data; and return a new cleaned dataset. We are testing with a recent systematic review dataset of ~2800 observations from >150 sources. This semi-automated interactive code has other benefits besides valid, upload-ready analysis data. First, a flexible, parameterized template enables faster work, easily repeated. Also, the code can reproducibly make documentation of cleaning done, or extraction history, or other reports on data, parameters, and results. And critically, an interactive notebook makes sophisticated coding accessible to data extractors, who tend to have less coding experience than research analysts.

description: We investigate the role of cooperation in wireless networks subject to a spatial degrees of freedom limitation. To address the worst case scenario, we consider a free-space line-of-sight type environment with no scattering and no fading. We identify three qualitatively different operating regimes that are determined by how the area of the network A, normalized with respect to the wavelength lambda, compares to the number of users n. In networks with sqrt{A}/lambda < sqrt{n}, the limitation in spatial degrees of freedom does not allow to achieve a capacity scaling better than sqrt{n} and this performance can be readily achieved by multi-hopping. This result has been recently shown by Franceschetti et al. However, for networks with sqrt{A}/lambda > sqrt{n}, the number of available degrees of freedom is min(n, sqrt{A}/lambda), larger that what can be achieved by multi-hopping. We show that the optimal capacity scaling in this regime is achieved by hierarchical cooperation. In particular, in networks with sqrt{A}/lambda> n, hierarchical cooperation can achieve linear scaling.

description: We have realised a 4-beam pyramidal magneto-optical trap ideally suited for future microfabrication. Three mirrors split and steer a single incoming beam into a tripod of reflected beams, allowing trapping in the four-beam overlap volume. We discuss the influence of mirror angle on cooling and trapping, finding optimum efficiency in a tetrahedral configuration. We demonstrate the technique using an ex-vacuo mirror system to illustrate the previously inaccessible supra-plane pyramid MOT configuration. Unlike standard pyramidal MOTs both the pyramid apex and its mirror angle are non-critical and our MOT offers improved molasses free from atomic shadows in the laser beams. The MOT scheme naturally extends to a 2-beam refractive version with high optical access. For quantum gas experiments, the mirror system could also be used for a stable 3D tetrahedral optical lattice.

Cosmological formation and chemical evolution of an elliptical galaxy

description: We aim at studying the effect of a cosmologically motivated gas infall law for the formation of a massive elliptical galaxy in order to understand its impact on the formation of the spheroids. We replace the empirical infall law of the model by Pipino & Matteucci with a cosmologically derived infall law for the formation of an elliptical galaxy. We constrast our predictions with observations. We also compare the obtained results with those of Pipino & Matteucci. We computed models with and without galactic winds: we found that models without wind predict a too large current SNIa rate. In particular, the cosmological model produces a current SNIa which is about ten times higher than the observed values. Moreover models without wind predict a large current SNII rate, too large even if compared with the recent GALEX data. The predicted SNII rate for the model with wind, on the other hand, is too low if compared with the star formation histories given by GALEX. Last but not least, the mean value for the [Mg/Fe] ratio in the dominant stellar population of the simulated galaxy, as predicted by the cosmological model, is too low if compared to observations. This is, a very important result indicating that the cosmological infall law is in contrast with the chemical evolution. A cosmologically derived infall law for an elliptical galaxy cannot reproduce all the chemical constraints given by the observations. The problem resides in the fact that the cosmologically derived infall law implies a slow gas accretion with consequent star formation rate active for a long period. In this situation low [Mg/Fe] ratios are produced for the dominant stellar population in a typical elliptical, at variance with observations.

description: Negative time delays—where photons appear to exit a medium earlier than expected—pose a fundamental challenge to conventional models of time and causality. While classical and quantum phase-based approaches successfully describe local time delays in dispersive and resonant media, they fail to account for the global nonlinear structure of time in interacting photon systems. In this work, we introduce a nonlinear global time framework, which extends local phase-induced delays into a self-consistent, resonance-driven temporal evolution.

Using an analytical model, we derive a generalized time function that scales with optical density, light intensity, and spectral width. Our results demonstrate that negative time delays emerge naturally as a consequence of phase shifts in nonlinear resonant environments, with an explicit dependence on Kerr-like interactions. We provide a quantitative comparison with existing theories, including Wigner delay time, dispersion-based group velocity anomalies, and superluminal wave propagation, and show that our approach offers a more comprehensive explanation of experimental observations.

This work also predicts new experimentally testable effects, such as the nonlinear scaling of global time delays with increasing photon intensity and resonant linewidth broadening. These findings have profound implications for quantum optics, ultrafast photonics, and optical communication, suggesting that time itself can be engineered as a tunable nonlinear quantity in resonant systems.

Our results pave the way for a deeper understanding of time as an emergent, nonlinear structure rather than a fixed background parameter.

description: Nachhaltigkeitsansätze getreu der Logik „Teilen statt Besitzen“ oder "Nutzen statt Besitzen" liegen voll im Trend und finden sich in vielen Bedürfnisfeldern wieder. Möbel mieten statt zu kaufen ist ein zunehmender Trend. Auch IKEA trägt den Folgen des Klimawandels, Ressourcenknappheiten und steigenden Lebenshaltungskosten im Bedürfnisfeld Wohnen Rechnung. Die vorliegende Fallstudie als sog. „Field Case“ thematisiert zum einen die Möglichkeiten und Grenzen eines innovativen Geschäftsmodells für die IKEA St. Gallen, das auf die Bereitstellung attraktiver möblierter Studieren-denwohnungen in der Ostschweiz abzielt. Zum anderen wird das für den IKEA-Konzern global interessante Tiny-House-Konzept näher unter die Lupe genommen. Der Case widmet sich als komplexes Lehr-Lern-Arrangement der Entwicklung eines Marketing-Konzepts bzw. innovativen Geschäftsmodells für IKEA und besteht aus vier Aufgabenblöcken: Analyse der Marktattraktivität für möblierte Studierendenwohnungen in St. Gallen, Markteintritt potenzieller Mitbewerber und Abwehrstrategien, Analyse und Weiterentwicklung des Geschäftsmodells für den globalen Markt incl. Controlling sowie Bedeutung und Auswahl von Kooperationspartnern. Umfangreiches Lehr-Lern-Material (Teaching Notes), eine sehr ausführliche didaktische Reflexion und zahlreiche aktuelle Quellen ermöglichen interessierten Dozierenden und Studierenden die Nutzung eines komplexen Lehr-Lern-Arrangements im Kontext des aus Nachhaltigkeitssicht bedeutsamen Bedürfnisfeld Wohnen.
Intensity fluctuations and photoelectric mixing of light beams
Creators: name: Burwell, Willis Bryan
Publisher: name: University of British Columbia
Year: 2011

description: Photoelectric mixing in a photodiode is used In this work as a statistical spectroscopic tool. A number of experiments were performed to determine the fluctuation spectrum generated by this process and the statistical properties of the light which might be deduced from the data. Due to practical limitations in attainable temperatures, blackbody sources were not able to produce an observable mixing above shot noise. Experiments were also carried out using line spectra from gas discharge lamps. The best source available was a 300 W Xenon lamp, emitting lines in the red, which under optimum conditions produced excess current fluctuations equal to 60% of shot noise. The observation of photoelectric mixing losing a gas laser source has already been reported in the literature, but the Gaussian distributed electric field model usually applied does not fit the experimental results. A new model was proposed in this thesis which considers the laser light as a narrow band of coherent light embedded in a relatively broad band of spontaneous light. Mixing between the signal and the spontaneous emission was considered to be the only observable effect due to experimental limitations. This model appeared to fit the data and gave some information about the statistical properties of the laser beam.
title: Wortakzent im Spannungsfeld von L1 und L2 : Eine empirische Untersuchung zur Akzentplatzierung in Internationalismen durch fortgeschrittene italophone DaF - Lernende

description: Der Beitrag präsentiert die Ergebnisse einer empirischen Studie zur Akzentplatzierung in deutschen Internationalismen durch fortgeschrittene italophone DaF-Lernende. Im Mittelpunkt steht die Frage, welche Faktoren eine korrekte Akzentplatzierung in der Fremdsprache Deutsch behindern bzw. begünstigen und welche Schlüsse sich daraus für die DaF-Didaktik ziehen lassen. Bei Internationalismen (z.B. dt. Analýse) besteht einerseits die Gefahr, dass die Lernenden abweichende Akzentmuster der L1-Kognaten (z.B. it. análisi) in die Zielsprache übernehmen. Andererseits kann der Erwerb prosodischer Regelmäßigkeiten der L2, insbesondere des paradigmatischen Pänultima-Akzents (Akzent auf der vorletzten Silbe flektierter Formen wie in Dialóge), korrekte Platzierungen fördern. Die Studie knüpft an die Überlegungen von Paschke (2010) an und unterzieht die dort formulierten Hypothesen einer empirischen Prüfung. Neben L1-Interferenz und Pänultima-Akzent werden die Effekte finaler SchwaSilben, lexikalischer Nachbarschaften (prosodisch kohärente oder inkohärente Wortausgänge) und der Lexemhäufigkeit analysiert. Versuchspersonen waren 26 italienische Germanistik-Studierende, die jeweils 171 Wortformen produzierten. Diese wurden aufgezeichnet, anschließend auditiv beurteilt und statistisch ausgewertet (Chi-Quadrat-Unterschiedstests, logistisches Regressionsmodell). Nach Einleitung, Darstellung der untersuchten Faktoren und Versuchsbeschreibung widmet sich der Beitrag im Hauptteil den einzelnen Hypothesen und ihrer empirischen Überprüfung. Abschließend werden die Resultate im Hinblick auf ihre didaktische Relevanz befragt.

description: Der vorliegende Beitrag hat zwei miteinander verbundene Ziele. Als Reaktion auf das häufige Plädoyer für ein stärkeres Einbeziehen des Texts und der Textlinguistik in den Fremdsprachenunterricht wird erstens eine an der Universität Bergen, Norwegen, durchgeführte Unterrichtsreihe im Bereich der kontrastiven Textlinguistik bzw. Textgrammatik vorgestellt und erörtert. Zweitens wird im Rahmen eines Pretest/Posttest/Follow-up-Test-Designs geprüft, inwieweit die Vermittlung der Vorfeld-Funktionen bei der Textvernetzung im norwegischen und im deutschen argumentativen Text dazu beiträgt, dass sich norwegische Deutschstudierende textlinguistischer Unterschiede bewusst werden und dies in ihrer Schreibpraxis umsetzen.
On the generalization of McVittie's model for an inhomogeneity in a cosmological spacetime

description: McVittie's spacetime is a spherically symmetric solution to Einstein's equation with an energy-momentum tensor of a perfect fluid. It describes the external field of a single quasi-isolated object with vanishing electric charge and angular momentum in an environment that asymptotically tends to a Friedmann--Lemaitre--Robertson--Walker universe. We critically discuss some recently proposed generalizations of this solution, in which radial matter accretion as well as heat currents are allowed. We clarify the hitherto unexplained constraints between these two generalizing aspects as being due to a geometric property, here called spatial Ricci-isotropy, which forces solutions covered by the McVittie ansatz to be rather special. We also clarify other aspects of these solutions, like whether they include geometries which are in the same conformal equivalence class as the exterior Schwarzschild solution, which leads us to contradict some of the statements in the recent literature.

description: We make a full tree level study of the signatures of anomalous gauge couplings of the Higgs boson at the CERN LHC via the semileptonic decay mode in WW scatterings. Both signals and backgrounds are studied at the hadron level for the Higgs mass in the range 115 GeV to 200 GeV. We carefully impose suitable kinematical cuts for suppressing the backgrounds. To the same sensitivity as in the pure leptonic mode, our result shows that the semileptonic mode can reduce the required integrated luminosity by a factor of 3. If the anomalous couplings in nature are actually larger than the sensitivity bounds shown in the text, the experiment can start the test for an integrated luminosity of 50 inverse fb.
