description: Grammatikfähigkeiten gelten als wichtiger Indikator einer SSES und spielen eine wesentliche Rolle beim Aufbau schriftsprachlicher Kompetenzen. Diese wiederum wirken sich auf Schullaufbahn und spätere Bildungschancen aus. Die vorliegende Arbeit beleuchtet ausgewählte Aspekte der Förderung von Grammatik in DaZ-­‐Unterricht und Logopädie. Unsere Forschungsfrage ist didaktischer Natur. Sie lautet: Wie unterstützen DaZ‐Lehrpersonen und Logopädinnen Kinder beim Grammatikerwerb des Deutschen? Im Theorieteil wird als Erstes die Vielfalt der Ansätze aufgezeigt, die in beiden Fachrichtungen – je nach theoretischen Prämissen – existieren. Anschliessend wird ein DaZ-­‐Lehrmittel aus logopädischer Sicht kommentiert. Am Ende des Theorieteils folgt eine Gegenüberstellung der Rahmenbedingungen beider Förderangebote. Der Schwerpunkt des zweiten, empirischen Teils liegt auf der qualitativen Auswertung eines Interviews mit einer DaZ‐Lehrerin und einer Logopädin. Ihre Aussagen zeigen in Bezug auf Grammatikförderung mehr Gemeinsamkeiten als Unterschiede. Sofern letztere zu einem vermehrten Austausch zwischen beiden Berufsgruppen führen, bergen eben diese Unterschiede das Potential für Synergien. Auf beiden Seiten manifestiert sich zudem ein Bedarf an Materialien zur Grammatikförderung.

description: The topological structure of complex networks has fascinated researchers for several decades, resulting in the discovery of many universal properties and reoccurring characteristics of different kinds of networks. However, much less is known today about the network dynamics: indeed, complex networks in reality are not static, but rather dynamically evolve over time. Our paper is motivated by the empirical observation that network evolution patterns seem far from random, but exhibit structure. Moreover, the specific patterns appear to depend on the network type, contradicting the existence of a "one fits it all" model. However, we still lack observables to quantify these intuitions, as well as metrics to compare graph evolutions. Such observables and metrics are needed for extrapolating or predicting evolutions, as well as for interpolating graph evolutions. To explore the many faces of graph dynamics and to quantify temporal changes, this paper suggests to build upon the concept of centrality, a measure of node importance in a network. In particular, we introduce the notion of centrality distance, a natural similarity measure for two graphs which depends on a given centrality, characterizing the graph type. Intuitively, centrality distances reflect the extent to which (non-anonymous) node roles are different or, in case of dynamic graphs, have changed over time, between two graphs. We evaluate the centrality distance approach for five evolutionary models and seven real-world social and physical networks. Our results empirically show the usefulness of centrality distances for characterizing graph dynamics compared to a null-model of random evolution, and highlight the differences between the considered scenarios. Interestingly, our approach allows us to compare the dynamics of very different networks, in terms of scale and evolution speed.

description: The stability of a single Belavin-Polyakov (BP) skyrmion in isotropic Heisenberg ferromagnet is studied. Such skyrmion is higher in energy than the uniform ferromagnetic state and is thus metastable. Starting from the lattice model in two spatial dimensions and using Maleyev-Dyson representation for spin operators, we examine the effects of magnon-magnon interaction for two quantities at $T=0$. First we discuss the self-energy corrections to magnon energy. Second we analyze the two-particle Green's function and possible bound states of two magnons. The simplicity of the model makes possible full analytic treatment of all relevant processes. We found that the magnons remain well-defined quasiparticles with a finite lifetime. The bound states of two magnons are suppressed near the skyrmion, although they are not excluded far away from it. A resonance for the magnons of dilational mode in the vicinity of BP skyrmion is also found, which leads to a redistribution of the spectral weight. We conclude that the BP skyrmion as the classical topological object is not destroyed by quantum fluctuations.

description: We consider a cyclically competing species model on a ring with global mixing at finite rate, which corresponds to the well-known Lotka-Volterra equation in the limit of infinite mixing rate. Within a perturbation analysis of the model from the infinite mixing rate, we provide analytical evidence that extinction occurs deterministically at sufficiently large but finite values of the mixing rate for any species number $N\ge3$. Further, by focusing on the cases of rather small species numbers, we discuss numerical results concerning the trajectories toward such deterministic extinction, including global bifurcations caused by changing the mixing rate.

description: Background: Atherosclerosis is the primary cause of cardiovascular diseases (CVDs), contributing to more than 33% of the annual deaths globally. Westernized dietary patterns, a high prevalence (50%) of overweight and obesity, and an increased incidence of glucose intolerance and type-2 diabetes are related to atherosclerosis. However, increased demand for functional foods has boosted the production of different foods to improve people’s life quality and decrease the CVDs’ risk. Nonetheless, functional foods targeting CVDs are scarce in the marketplace. Scope and approach: To perform a multidisciplinary and cross-sectoral approach by linking atherosclerosis bio-markers, potential bioactive compounds (e.g., phenolics), and food technology, besides scientific limitations, we propose a practical step-by-step guide to designing functional foods. First, a comprehensive and up-to-date overview of atherosclerosis is provided, focusing on the inflammation markers to counteract its onset and proression. Then, a structure-based–(SBDD) or ligand-based drug design (LBDD) approach is presented, and illustrated by the incorporation of vescalagin, a phenolic compound from jaboticaba seed, into a functional food to mitigate atherosclerosis. Key findings and conclusions: Tailored functional foods added with phenolic compounds can be designed through computational approaches predicting their bioactivity. Together with chemical analyses, mathematical models can explore a vast array of molecular mechanisms, allowing the discovery of novel bioactive compound sources. Altogether, food science/technology, nutrition, and structure- and ligand-based approaches should be combined to support the design of tailor-made functional foods/nutraceuticals to contribute to public health interventions related to atherosclerosis and other cardiometabolic diseases

description: Grid computing is intended to offer an easy and seamless access to remote resources. The scheduling task of allocating these resources automatically to user jobs is an essential part of a grid environment. This work discusses the evaluation and design of different scheduling strategies. A concept for the design process of such a scheduling system is presented. The evaluation of scheduling algorithms for single parallel machines is done by theoretical analysis and by simulation experiments. The theoretical approach by competitive analysis lead to bounds for the worst-case scenarios. As there is great interest in the scheduling performance of a real system installation, simulations have been applied for further evaluation. In addition to the theoretical analysis, the presented preemptive scheduling algorithm is also effcient in terms of makespan and average response time in a real system scenario if compared to other scheduling algorithms. In some of the examined scenarios the algorithm could outperform other common algorithms such as backfilling. Based on these results, scheduling algorithms for the grid environment have been developed. On one hand, these methods base on modifications of the examined conventional scheduling strategies for single parallel machines. On the other hand, a scheduling strategy with a market economic approach is presented. As a proof of concept a possible architecture of a scheduling environment is presented, which has been used for the evaluation of the presented algorithms. The work ends with a brief conclusion on the discussed scheduling strategies and gives an outlook on future work.
Holographic energy loss in non-relativistic backgrounds

description: In this paper, we study some aspects of energy loss in non-relativistic theories from holography. We analyze the energy lost by a rotating heavy point particle along a circle of radius $l$ with angular velocity $ω$ in theories with general dynamical exponent $z$ and hyperscaling violation exponent $θ$. It is shown that this problem provides a novel perspective on the energy loss in such theories. A general computation at zero and finite temperature is done and it is shown that how the total energy loss rate depends non-trivially on two characteristic exponents $(z,θ)$. We find that at zero temperature there is a special radius $l_c$ where the energy loss is independent of different values of $(θ,z)$. Also at zero temperature, there is a crossover between a regime in which the energy loss is dominated by the linear drag force and by the radiation because of the acceleration of the rotating particle. We find that the energy loss of the particle decreases by increasing $θ$ and $z$. We note that, unlike in the zero temperature, there is no special radius $l_c$ at finite temperature case.

description: Additive manufacturing, also known as 3D printing, is an advanced manufacturing technique that allows the fabrication of arbitrary macroscopic and microscopic objects. All 3D printing systems require large optical elements or nozzles in proximity to the built structure. This prevents their use in applications in which there is no direct access to the area where the objects have to be printed. Here, we demonstrate three-dimensional microfabrication based on two-photon polymerization (TPP) with sub diffraction-limited resolution through an ultra-thin, 50 mm long printing nozzle of 560 micrometers in diameter. Using wavefront shaping, femtosecond infrared pulses are focused and scanned through a multimode optical fiber (MMF) inside a photoresist that polymerizes via two-photon absorption. We show the construction of arbitrary 3D structures of 500 nm resolution on the other side of the fiber. To our knowledge, this is the first demonstration of microfabrication through a multimode optical fiber. Our work represents a new area which we refer to as endofabrication.

description: Die Arbeit behandelt das Verschleißverhalten von Rädern mit Polyurethanbandage, wie sie in Reibradantrieben Verwendung finden. Zu diesem Zweck wird ein Versuchsaufbau beschrieben und ein Untersuchungsablauf entwickelt. Bei den Untersuchungen wird insbesondere auf den Einfluss von Zwischenstoffen in der Kontaktfläche zwischen Rad und Gegenfläche eingegangen, dabei wird in der Kontaktfläche eine Tangentialkraft übertragen. Die folgenden Zwischenstoffe werden betrachtet:- Sand- Wasser- Sand mit Wasser- Schneid-Kühl-Emulsion (Esso Kutwell 40)- Metallspäne- Schneid-Kühl-Emulsion mit Metallspänen. Zur Kontrolle werden Untersuchungen ohne Einwirkung von Zwischenstoffen herangezogen. Die Versuche werden auf einem Rollenprüfstand durchgeführt. Das Verschleißverhalten wird mittels des Gewichtsverlustes der Prüflinge innerhalb der Versuchsdauer von 24 Stunden ermittelt. Zusätzlich wird die Oberflächenschädigung des Rades sowohl makroskopisch als auch mikroskopisch betrachtet und beurteilt. Die Prüflinge werden während der Versuche an ihrer Belastungsgrenze beansprucht. In der Auswertung der Untersuchungen wird neben des Einflusses der Zwischenstoffe auf das Verschleißverhalten auch der Einfluss von Bandagenhärte, Vorvernetzer des Polyurethans, mechanischer Beanspruchung und Schlupf betrachtet. Mit Hilfe der Untersuchungsergebnisse sollen Reibradantriebe unter der Berücksichtigung besonderer Störeinflüsse in Form von Zwischenstoffen in der Kontaktfläche verschleißoptimiert ausgelegt werden.

description: Quantization of the gravitational field may allow the existence of a decay channel of black holes into white holes with an explicit time-reversal symmetry. The definition of a meaningful decay probability for this channel is studied in spherically symmetric situations. As a first nontrivial calculation, we present the functional integration over a set of geometries using a single-variable function to interpolate between black-hole and white-hole geometries in a bounded region of spacetime. This computation gives a finite result which depends only on the Schwarzschild mass and a parameter measuring the width of the interpolating region. The associated probability distribution displays an exponential decay law on the latter parameter, with a mean lifetime inversely proportional to the Schwarzschild mass. In physical terms this would imply that matter collapsing to a black hole from a finite radius bounces back elastically and instantaneously, with negligible time delay as measured by external observers. These results invite to reconsider the ultimate nature of astrophysical black holes, providing a possible mechanism for the formation of black stars instead of proper general relativistic black holes. The existence of both this decay channel and black stars can be tested in future observations of gravitational waves.

description: Objective: The authors sought to determine whether Black sexual minority individuals were more likely than White sexual minority individuals to postpone or avoid professional mental health care (PMHC) and, if so, to identify the reasons for postponing or avoiding care. Methods: Analyses were conducted with a subsample of cisgender Black (N=78) and White (N=398) sexual minority individuals from a larger survey of U.S. adults administered via MTurk in 2020 (N=1,012). Logistic regression models were used to identify racial differences in overall postponement or avoidance of care as well as differences in the prevalence of each of nine reasons for postponing or avoiding care. Results: Black sexual minority individuals were more likely than their White counterparts to report ever postponing or avoiding PMHC (average marginal effect [AME]=13.7 percentage points, 95% CI=5.4–21.9). Black sexual minority people also were more likely than their White counterparts to cite beliefs that they should work out their problems on their own (AME=13.1 percentage points, 95% CI=1.2–24.9) or with family and friends (AME=17.5 percentage points, 95% CI=6.0–29.1) and to cite providers’ refusal to treat them (AME=17.4 percentage points, 95% CI=7.6–27.1) as reasons for postponing or avoiding care. Conclusions: Black sexual minority individuals were more likely than their White counterparts to report delaying or avoiding PMHC. Personal beliefs about managing mental health and providers’ refusal to offer treatment influenced Black sexual minority individuals’ willingness or ability to seek PMHC.

description: Voice Of the People (VOP) is a nonpartisan organization working to re-anchor our democracy in its founding principles by giving ‘We the People’ a greater and more effective voice in government. VOP champions innovative methods and technology – notably online public consultations – that enable the American people to play a role in the policymaking process and provide policymakers with a more accurate understanding of the views of their constituents. The Program for Public Conultation conducts policymaking simulations, which are an online process that puts citizens in the shoes of elected officials by simulating the process they go through in making policy decisions. Each simulation introduces a broader policy topic and then presents a series of modules that address a specific policy option that is currently under consideration in the current discourse. For each module, respondents: 1) receive a short briefing on a policy issue and the option or options for addressing it; 2) evaluate arguments for and against the policy options; and 3) finally, make their recommendation for what their elected officials should do.
description: – Large bipartisan majorities favor proposals that would prohibit the sale of US real estate and oil reserves to entities linked to foreign adversaries, including China and Russia. Three-quarters (73%) support a prohibition on the sale of property, including farmland; while 72% support a prohibition on selling oil from US oil reserves, according to an in-depth study by the Program for Public Consultation at the University of Maryland’s School of Public Policy. Concerns among Members of Congress over the US’ economic relations with its adversaries, particularly China, have been on the rise. This has been caused in part by increasing purchases of US agricultural land by Chinese companies; as well as the sale of US oil reserves to Chinese energy companies. Members of Congress and state legislatures have introduced legislation to address this issue. Rep. Gallagher, the Chairman of the House select committee on China, recently put forward a bipartisan bill which would give federal officials greater authority to block companies affiliated with foreign adversaries from acquiring certain US lands, particularly those near sensitive sites (e.g. military bases, telecommunication infrastructure.)

description: We have developed a single-shot terahertz time-domain spectrometer to perform optical-pump/terahertz-probe experiments in pulsed, high magnetic fields up to 30 T. The single-shot detection scheme for measuring a terahertz waveform incorporates a reflective echelon to create time-delayed beamlets across the intensity profile of the optical gate beam before it spatially and temporally overlaps with the terahertz radiation in a ZnTe detection crystal. After imaging the gate beam onto a camera, we can retrieve the terahertz time-domain waveform by analyzing the resulting image. To demonstrate the utility of our technique, we measured cyclotron resonance absorption of optically excited carriers in the terahertz frequency range in intrinsic silicon at high magnetic fields, with results that agree well with published values.

description: In this paper, we present an efficient Dynamic Programing framework for optimal planning and control of legged robots. First we formulate this problem as an optimal control problem for switched systems. Then we propose a multi--level optimization approach to find the optimal switching times and the optimal continuous control inputs. Through this scheme, the decomposed optimization can potentially be done more efficiently than the combined approach. Finally, we present a continuous-time constrained LQR algorithm which simultaneously optimizes the feedforward and feedback controller with $O(n)$ time-complexity. In order to validate our approach, we show the performance of our framework on a quadrupedal robot. We choose the Center of Mass dynamics and the full kinematic formulation as the switched system model where the switching times as well as the contact forces and the joint velocities are optimized for different locomotion tasks such as gap crossing, walking and trotting.

description: The formation and properties of envelope dispersive shock wave (DSW) excitations from repulsive nonlinear waves in a magnetic film are studied. Experiments involve the excitation of a spin-wave step pulse in a low-loss magnetic Y$_3$Fe$_5$O$_{12}$ thin film strip, in which the spin-wave amplitude increases rapidly, realizing the canonical Riemann problem of shock theory. Under certain conditions, the envelope of the spin-wave pulse evolves into a DSW that consists of an expanding train of nonlinear oscillations with amplitudes increasing from front to back, terminated by a black soliton. The onset of DSW self-cavitation, indicated by a point of zero power and a concomitant 180 phase jump, is observed for sufficiently large steps, indicative of the bidirectional dispersive hydrodynamic nature of the DSW. The experimental observations are interpreted with theory and simulations of the nonlinear Schrödinger equation.

Doping Rb or Cs into KMgBi can drive the transition between the two phases. The materials can also be turned into Weyl semimetals and topological insulators by explicitly or spontaneously breaking time-reversal symmetry and C$_4$ lattice symmetry respectively.

description: In this paper, we clarify the mechanisms underlying a general phenomenon present in pulse-coupled heterogeneous inhibitory networks: inhibition can induce not only suppression of the neural activity, as expected, but it can also promote neural reactivation. In particular, for globally coupled systems, the number of firing neurons monotonically reduces upon increasing the strength of inhibition (neurons' death). However, the random pruning of the connections is able to reverse the action of inhibition, i.e. in a sparse network a sufficiently strong synaptic strength can surprisingly promote, rather than depress, the activity of the neurons (neurons' rebirth). Thus the number of firing neurons reveals a minimum at some intermediate synaptic strength. We show that this minimum signals a transition from a regime dominated by the neurons with higher firing activity to a phase where all neurons are effectively sub-threshold and their irregular firing is driven by current fluctuations. We explain the origin of the transition by deriving an analytic mean field formulation of the problem able to provide the fraction of active neurons as well as the first two moments of their firing statistics. The introduction of a synaptic time scale does not modify the main aspects of the reported phenomenon. However, for sufficiently slow synapses the transition becomes dramatic, the system passes from a perfectly regular evolution to an irregular bursting dynamics. In this latter regime the model provides predictions consistent with experimental findings for a specific class of neurons, namely the medium spiny neurons in the striatum.

description: We show that one can obtain logarithmic improvements of $L^2$ geodesic restriction estimates for eigenfunctions on 3-dimensional compact Riemannian manifolds with constant negative curvature. We obtain a $(\logλ)^{-\frac12}$ gain for the $L^2$-restriction bounds, which improves the corresponding bounds of Burq, Gérard and Tzvetkov, Hu, Chen and Sogge. We achieve this by adapting the approaches developed by Chen and Sogge, Blair and Sogge, Xi and the author. We derive an explicit formula for the wave kernel on 3D hyperbolic space, which improves the kernel estimates from the Hadamard parametrix in Chen and Sogge. We prove detailed oscillatory integral estimates with fold singularities by Phong and Stein and use the Poincaré half-space model to establish bounds for various derivatives of the distance function restricted to geodesic segments on the universal cover $\mathbb{H}^3$.

description: In this article we present a theoretical construction of spacetimes with a thin shell that joins two different local cosmic string geometries. We study two types of global manifolds, one representing spacetimes with a thin shell surrounding a cosmic string or an empty region with Minkowski metric, and the other corresponding to wormholes which are not symmetric across the throat located at the shell. We analyze the stability of the static configurations under perturbations preserving the cylindrical symmetry. For both types of geometries we find that the static configurations can be stable for suitable values of the parameters.

description: Kinematic edges in the invariant mass distributions of different final state particles are typically a signal of new physics. In this work we propose a scenario wherein these edges could be utilised in discriminating between different classes of models. To this effect, we consider the resonant production of a heavy Higgs like resonance (H 1 ) as a case study. Such states are a characteristic feature of many new physics scenarios beyond the Standard Model (SM). In the event of a discovery, it is essential to identify the true nature of the underlying theory. In this work we propose a channel, $H_1 \rightarrow t_2 t$, where t_2 is a vector-like gauge singlet top-partner that decays into W b, Zt, ht. Invariant mass distributions constructed out of these final states are characterized by the presence of kinematic edges, which are unique to the topology under consideration. Further, since all the final state particles are SM states, the position in the edges of these invariant mass distributions can be used to exclusively determine the masses of the resonances. Observation of these features are meant to serve as a trigger, thereby mandating a more detailed analysis in a particular direction of parameter space. The absence of these edge like features, in the specific invariant mass distributions considered here, in minimal versions of supersymmetric models (MSSM) also serves as a harbinger of such non MSSM-like scenarios.

description: In der Astrophysik spielt Mathematik eine zentrale Rolle. Schon einfache Anwendungen Newtonscher Mechanik und die Durchdringung der dazugehörigen Mathematik machen es möglich, spektakuläre Vorhersagen über das Schicksal der Planeten und Monde in unserem Sonnensystem zu treffen. Welche Rolle die Mathematik hierbei genau spielt, warum das eine physikalische Gesetz den Ausschlag gibt und die anderen vernachlässigt werden können und wie ein(e) Astrophysiker(in) hier die Mathematik benutzt all diese Fragen sind nur zu beantworten im wirklichen Austausch mit Wissenschaftlern dieses Gebiets. Um so etwas wie authentischen Mathematikunterricht [4] zu ermöglichen, der den praktischen und didaktischen Anforderungen von Unterricht in der Schule genügt, bedarf es jedoch mehr: Wissenschaftler, Lehrer, Mathematikdidaktiker und Schüler müssen einander Einsicht und Teilnahme gewähren in die eigenen Denk- und Lernmodelle [3]. Statt um eine Einleitung in ein Thema geht es hier vielmehr um ausleitenden Unterricht, was andere Kompetenzen und Haltungen in Hinblick auf das eigene Fach erfordert.
