description: Der vorliegende Beitrag vermittelt einen Einblick in ein Forschungsprojekt, welches den Zürcher Dialekt von Jugendlichen mit Migrationshintergrund untersucht. Ausgehend vom Ansatz einer perzeptiven Varietätenlinguistik stellen wir zunächst die Frage, ob multiethno­lektales Sprechen von gleichaltrigen Jugendlichen eher kategorisch oder als Kontinuum wahrgenommen wird. Danach vergleichen wir die Ergebnisse eines Rating-Experiments mit der Ausprägung zweier linguistischer Variablen, nämlich der Dauer anlautender Frikative und dem Anteil an lexikalischen Interferenzen aus dem Standarddeutschen im verwendeten Dialektwortschatz. Dabei zeigt sich einerseits, dass die Jugendlichen in der Tat verschiedene Grade der Multiethnolektalität wahrnehmen – und zwar in Form eines Kontinuums und nicht als klar voneinander abgegrenzte Kategorien. Andererseits lassen sich in der Sprach­produktion bestimmte Muster ausmachen, die mit der perzeptiven Einordnung der Sprechenden korrelieren und als eine Art ‘Dialekttransformation’ des Zürichdeutschen charakterisiert werden können.

description: We present a first-principles study of the cross-plane thermal conductivity $κ_{\perp}$ in a wide variety of semiconductor thin films. We introduce a simple suppression model that matches variance-reduced Monte Carlo simulations with ab-initio phonon dispersions and scattering rates within $\leq 5\%$ even for anisotropic compounds. This, in turn, enables accurate $κ_{\perp}$ reconstruction from tabulated cumulative conductivity curves $κ_Σ(Λ_{\perp})$. We furthermore reveal, and explain, a distinct quasiballistic regime characterised by a fractional thickness dependence $κ_{\perp} \sim L^{2-α}$ in alloys (where $α$ is the Lévy exponent) and logarithmic dependence $κ_{\perp} \sim \ln(L)$ in single crystals. These observations culminate in the formulation of two compact parametric forms for $κ_{\perp}(L)$ that can fit the first-principles curves across the entire ballistic-diffusive range within a few percent for all investigated compounds.

description: Every randomized clinical study needs a method of allocating treatments to patients to ensure the basis for a valid statistical inference. In the literature, the susceptibility of randomization procedures to both selection and chronological bias is already well studied. However, no optimality statement is given for the selection of a randomization procedure, when both types of bias are present simultaneously. Therefore, a linked assessment criterion for the selection of an appropriate randomization procedure is presented. The linked assessment criterion is based on desirability functions. For the calculation of the optimality score of a randomization procedure the importance of the investigated types of bias is considered. Several randomization procedures are compared for the sample sizes 12, 50 and 200. Finally, a recommendation for the choice of a randomization procedure is given in the presence of both selection and chronological bias.

description: Progress in understanding the coupling between plasma instabilities in the equatorial electrojet based on a unified fluid model is reported. A deeper understanding of the linear and nonlinear evolution and the coupling of the gradient-drift and Farley-Buneman instabilities is achieved by studying the effect of different combinations of the density-gradient scale-lengths (Ln) and cross-field (E?B) drifts on the plasma turbulence. Mechanisms and channels of energy transfer are illucidated for these multiscale instabilities. Energy for the unified model is examined, including the injected, conservative redistribution (between fields and scales), and ultimate dissipation. Various physical mechanisms involved in the energetics are categorized as sources, sinks, nonlinear transfer, and coupling to show that the system satisfies the fundamental law of energy Oonservation. The physics of the nonlinear transfer terms is studied to identify their roles in producing energy cascades { the transference of energy from the dominant unstable wavenumbers and driving irregularities of different scale-lengths. The theory of two-step energy cascading to generate the 3-meter plasma irregularities in the equatorial electrojet is verified. In addition, the nonlinearity of the system allows the possibility for a reverse energy cascading, responsible for generating large-scale plasma structures at the top of the electrojet.

Measurement of the distributions of event-by-event flow harmonics in lead--lead collisions at $\sqrt{s_\it{NN}}=2.76$ TeV with the ATLAS detector at the LHC

description: The distributions of event-by-event harmonic flow coefficients v_n for n=2-4 are measured in sqrt(s_NN)=2.76 TeV Pb+Pb collisions using the ATLAS detector at the LHC. The measurements are performed using charged particles with transverse momentum pT> 0.5 GeV and in the pseudorapidity range |eta|<2.5 in a dataset of approximately 7 ub^-1 recorded in 2010. The shapes of the v_n distributions are described by a two-dimensional Gaussian function for the underlying flow vector in central collisions for v_2 and over most of the measured centrality range for v_3 and v_4. Significant deviations from this function are observed for v_2 in mid-central and peripheral collisions, and a small deviation is observed for v_3 in mid-central collisions. It is shown that the commonly used multi-particle cumulants are insensitive to the deviations for v_2. The v_n distributions are also measured independently for charged particles with 0.51 GeV. When these distributions are rescaled to the same mean values, the adjusted shapes are found to be nearly the same for these two pT ranges. The v_n distributions are compared with the eccentricity distributions from two models for the initial collision geometry: a Glauber model and a model that includes corrections to the initial geometry due to gluon saturation effects. Both models fail to describe the experimental data consistently over most of the measured centrality range.

description: It is quite relevant the extension of decoration transformation for quantum spin models since most of the real materials could be well described by Heisenberg type models. Here we propose an exact quantum decoration transformation and also showing interesting properties such as the persistence of symmetry and the symmetry breaking during this transformation. Although the proposed transformation, in principle, cannot be used to map exactly a quantum spin lattice model into another quantum spin lattice model, since the operators are non-commutative. However, it is possible the mapping in the "classical" limit, establishing an equivalence between both quantum spin lattice models. To study the validity of this approach for quantum spin lattice model, we use the Zassenhaus formula, and we verify how the correction could influence the decoration transformation. But this correction could be useless to improve the quantum decoration transformation because it involves the second-nearest-neighbor and further nearest neighbor couplings, which leads into a cumbersome task to establish the equivalence between both lattice models. This correction also gives us valuable information about its contribution, for most of the Heisenberg type models, this correction could be irrelevant at least up to the third order term of Zassenhaus formula. This transformation is applied to a finite size Heisenberg chain, comparing with the exact numerical results, our result is consistent for weak xy-anisotropy coupling. We also apply to bond-alternating Ising-Heisenberg chain model, obtaining an accurate result in the limit of the quasi-Ising chain.

Continuous Cocycle Superrigidity for Shifts and Groups with One End

description: In this article, we prove that if a finitely generated group $G$ is not torsion then a necessary and sufficient condition for every full shift over $G$ has (continuous) cocycle superrigidity is that $G$ has one end. It is a topological version of the well known Popa's measurable cocycle superrigidity theorem. For the proof of sufficient condition, we introduce a new specification property for shifts over general groups which play a similar role as malleable property in the measurable setting. This new specification property is good enough for us to extend the method using homoclinic equivalence relation that was introduced by Klaus Schmidt to study cocycle rigidity for $\mathbb{Z}^d$-shifts. Indeed, in this direction we prove this superrigidity result for more certain general systems. And for the converse, we apply Specker's characterization for ends of groups via the associated first cohomology groups to get the result. Finally, combining our results with a result of Xin Li, we have an application in continuous orbit equivalence rigidity.

description: We present a code for generating synthetic SEDs and intensity maps from Smoothed Particle Hydrodynamics simulation snapshots. The code is based on the Lucy (1999) Monte Carlo Radiative Transfer method, i.e. it follows discrete luminosity packets, emitted from external and/or embedded sources, as they propagate through a density field, and then uses their trajectories to compute the radiative equilibrium temperature of the ambient dust. The density is not mapped onto a grid, and therefore the calculation is performed at exactly the same resolution as the hydrodynamics. We present two example calculations using this method. First, we demonstrate that the code strictly adheres to Kirchhoff's law of radiation. Second, we present synthetic intensity maps and spectra of an embedded protostellar multiple system. The algorithm uses data structures that are already constructed for other purposes in modern particle codes. It is therefore relatively simple to implement.

description: We develop a Magnus formalism for periodically driven systems which provides an expansion both in the driving term and the inverse driving frequency, applicable to isolated and dissipative systems. We derive explicit formulas for a driving term with a cosine dependence on time, up to fourth order. We apply these to the steady state of a classical parametric oscillator coupled to a thermal bath, which we solve numerically for comparison. Beyond dynamical stabilization at second order, we find that the higher orders further renormalize the oscillator frequency, and additionally create a weakly renormalized effective temperature. The renormalized oscillator frequency is quantitatively accurate almost up to the parametric instability, as we confirm numerically. Additionally, a cut-off dependent term is generated, which indicates the break-down of the hierarchy of time scales of the system, as a precursor to the instability. Finally, we apply this formalism to a parametrically driven chain, as an example for the control of the dispersion of a many-body system.

description: We discuss the statistics of emission of photons by a single atom or ion illuminated by a laser beam at the frequency of quasi-resonance between two energy levels, a situation that corresponds to real experiments. We extend this to the case of two laser beams resonant with the energy differences between two excited levels and the ground state (three level atom in V-configuration). We use a novel approach of this type of problem by considering Kolmogorov equation for the probability distribution of the atomic state which takes into account first the deterministic evolution of this state under the effect of the incoming laser beam and the random emission of photons during the spontaneous decay of the excited state(s) to the ground state. This approach yields solvable equations in the two level atom case. For the three level atom case we set the problem and define clearly its frame. The results obtained are valid both in the opposite limits of rare and of frequent spontaneous decay, compared to the period of the optical Rabi oscillations due to the interaction between the resonant excitation and the atomic levels. Our theory gives access to various statistical properties of the fluorescence light, including one showing that its fluctuations in time are not invariants under time reversal. This result puts in evidence the fundamentally irreversible character of quantum measurements, represented here by the emission of photons of fluorescence.

description: We study the chemical ordering in Bi$_2$Te$_{3-x}$Se$_x$ grown by molecular beam epitaxy on Si substrates. We produce films in the full composition range from x = 0 to 3, and determine their material properties using energy dispersive X-ray spectroscopy, X-ray diffraction and Raman spectroscopy. By fitting the parameters of a kinetic growth model to these results, we obtain a consistent description of growth at a microscopic level. Our main finding is that despite the incorporation of Se in the central layer being much more probable than that of Te, the formation of a fully ordered Te-Bi-Se-Bi-Te layer is prevented by kinetic of the growth process. Indeed, the Se concentration in the central layer of Bi$_2$Te$_2$Se$_1$ reaches a maximum of only $\approx$ 75% even under ideal growth conditions. A second finding of our work is that the intensity ratio of the 0 0 12 and 0 0 6 X-ray reflections serves as an experimentally accessible quantitative measure of the degree of ordering in these films.

description: We argue that all consistent 4D quantum field theories obey a spacetime-averaged weak energy inequality $\langle T^{00} \rangle \ge -C/L^4$, where $L$ is the size of the smearing region, and $C$ is a positive constant that depends on the theory. If this condition is violated, the theory has states that are indistinguishable from states of negative total energy by any local measurement, and we expect instabilities or other inconsistencies. We apply this condition to 4D conformal field theories, and find that it places constraints on the OPE coefficients of the theory. The constraints we find are weaker than the "conformal collider" constraints of Hofman and Maldacena. We speculate that there may be theories that violate the Hofman-Maldacena bounds, but satisfy our bounds. In 3D CFTs, the only constraint we find is equivalent to the positivity of 2-point function of the energy-momentum tensor, which follows from unitarity. Our calculations are performed using momentum-space Wightman functions, which are remarkably simple functions of momenta, and may be of interest in their own right.

description: Gaberdiel and Gopakumar recently proposed that the tensionless limit of string theory on $AdS_3 \times S^3 \times T^4$ takes the form of a higher spin theory with a gauge algebra that is referred to as the higher spin square. In this note, we formulate the linearized Vasiliev-type equations which describe a matter field coupled to the higher spin square. We study the particle spectrum of this field and show that it accounts for the entire untwisted sector of the dual symmetric orbifold CFT, thereby confirming a conjecture by Gaberdiel and Gopakumar. In doing so, we pinpoint the group-theoretic data which determine the spectrum of a matter field coupled to a general higher spin algebra, which we illustrate by revisiting the theory based on the $hs[1/2]$ algebra.

description: The detection of quasars at $z>6$ unveils the presence of supermassive black holes (BHs) of a few billion solar masses. The rapid formation process of these extreme objects remains a fascinating and open issue. Such discovery implies that seed black holes must have formed early on, and grown via either rapid accretion or BH/galaxy mergers. In this theoretical review, we discuss in detail various BH seed formation mechanisms and the physical processes at play during their assembly. We discuss the three most popular BH formation scenarios, involving the (i) core-collapse of massive stars, (ii) dynamical evolution of dense nuclear star clusters, (iii) collapse of a protogalactic metal free gas cloud. This article aims at giving a broad introduction and an overview of the most advanced research in the field.

description: This is a presentation made in the frame of the course on "Culture and Identity" at Stockholm University for students at the level of French III. The lesson is about the construction of the Swiss democracy with the use of the referendum. Why is there a political consensus in Switzerland?

 Lorsqu’on se penche sur l’histoire de la construction politique de la Suisse, on remarque l’importance du principe de représentativité au sein des nouveaux cantons qui rejoignent la confédération. À l’ère contemporaine, l’adoption des droits populaires (initiative populaire, référendum) paraît essentielle dans le contexte confédéral puisqu’elle garantit une forme d’autonomie locale. Ces droits populaires caractérisent le système politique suisse et sont largement associés à sa neutralité. Non seulement la Suisse se tient également à l’extérieur de l’espace économique et européen, mais lorsqu’on se penche sur les attitudes de la population à l’égard de l’Union européenne, on constate aussi un fossé culturel entre les cantons alémaniques et les cantons romands. Le terme de Röstisgraben a été forgé pour désigner la fracture culturelle entre une Suisse plus tolérante et plus ouverte sur le monde et une autre davantage préoccupée par la préservation de sa souveraineté, la restriction de l’immigration et la limitation des interventions de l’État fédéral. Le terme de Röstisgraben provient en réalité du suisse-allemand et désigne la manière de préparer les pommes de terre («Rösti»). Les Suisses-allemands voient le Rösti comme un plat national contrairement aux Suisses francophones et latins qui valorisent la fondue ou la polenta. Derrière ce terme, pointe un conflit culturel latent entre les cantons francophones et les cantons germanophones. Le Röstisgraben correspond-il toutefois au clivage linguistique entre les cantons francophones (les cantons romands) et les cantons alémaniques (cantons germanophones)?

description: This paper presents a novel reversible data hiding (RDH) algorithm for gray-scaled images, in which the prediction-error of prediction error (PPE) of a pixel is used to carry the secret data. In the proposed method, the pixels to be embedded are firstly predicted with their neighboring pixels to obtain the corresponding prediction errors (PEs). Then, by exploiting the PEs of the neighboring pixels, the prediction of the PEs of the pixels can be determined. And, a sorting technique based on the local complexity of a pixel is used to collect the PPEs to generate an ordered PPE sequence so that, smaller PPEs will be processed first for data embedding. By reversibly shifting the PPE histogram (PPEH) with optimized parameters, the pixels corresponding to the altered PPEH bins can be finally modified to carry the secret data. Experimental results have implied that the proposed method can benefit from the prediction procedure of the PEs, sorting technique as well as parameters selection, and therefore outperform some state-of-the-art works in terms of payload-distortion performance when applied to different images.

Weighted Pushdown Systems with Indexed Weight Domains

description: The reachability analysis of weighted pushdown systems is a very powerful technique in verification and analysis of recursive programs. Each transition rule of a weighted pushdown system is associated with an element of a bounded semiring representing the weight of the rule. However, we have realized that the restriction of the boundedness is too strict and the formulation of weighted pushdown systems is not general enough for some applications. To generalize weighted pushdown systems, we first introduce the notion of stack signatures that summarize the effect of a computation of a pushdown system and formulate pushdown systems as automata over the monoid of stack signatures. We then generalize weighted pushdown systems by introducing semirings indexed by the monoid and weaken the boundedness to local boundedness.

description: The weak coupling asymptotics to order $γ$ of the ground state energy of the delta-function Fermi gas, derived heuristically in the literature, is here made rigorous. Further asymptotics are in principle computable. The analysis applies to the Gaudin integral equation a method previously used by one of the authors for the asymptotics of large Toeplitz matrices.

Rotational relaxation time as unifying time scale for polymer and fiber drag reduction

description: Using hybrid Direct Numerical Simulation with Langevin dynamics, a comparison is performed between polymer and fiber stress tensors in turbulent flow. The stress tensors are found to be similar, suggesting a common drag reducing mechanism in the onset regime for both flexible polymers and rigid fibers. Since fibers do not have an elastic backbone, this must be a viscous effect. Analysis of the viscosity tensor reveals that all terms are negligible, except the off-diagonal shear viscosity associated with rotation. Based on this analysis, we identify the rotational orientation time as the unifying time scale setting a new time criterion for drag reduction by both flexible polymers and rigid fibers.

title: Congestion in acute heart failure trials and registries: a systematic review
Creators: name: Ahmad, Faheem A.
Publisher: name: University of Glasgow
Year: 2020
Subjects: subject: Acute heart failure, congestion, pulmonary congestion.

description: Introduction: The term “congestion” is used to describe a broad range of clinical presentations. Congestion is a variably understood and assessed entity. Patients develop a mixture of central (pulmonary) and/or peripheral (non-pulmonary) symptoms of congestion. These are likely to have different pathophysiological mechanisms. The presence of subclinical congestion is an independent risk factor for early re-hospitalisation and morbidity. Novel techniques to assess congestion have been developed, but their clinical role is not yet established. Methods: I performed two systematic reviews of acute heart failure (AHF) trials and registries from Jan 1, 2001 to Dec 31, 2018 on EMBASE and MEDLINE to determine the methods and techniques used to assess and grade congestion. The search terms utilised were “acute heart failure”, “decompensated heart failure” and “hospitalized heart failure”. The minimum enrolment numbers were 180 patients for randomised trials and 2,000 patients for registries. Results: 18 major acute heart failure registries and 21 major trials were analysed. There are no standardised methods for assessing central or peripheral congestion. Acute heart failure trials preferentially recruited patients with pulmonary congestion (manifesting as dyspnoea at rest). In 6 of 8 trials with available data, this was mandatory for 100% of patients. By contrast, for large registry trials this rate ranged from 34 to 73%. Dyspnoea on exertion was a more predominant presentation (61 to 95%). With the exception of a chest X-ray, no trial or registry routinely utilised non-invasive (e.g. lung ultrasound) or invasive (e.g. right heart catheterisation) techniques to objectively and systematically quantify either congestion on recruitment or congestion on discharge. Conclusion: Congestion is variably assessed and defined. Internationally agreed definitions of the presence and severity of congestion are required. These definitions should include conventional symptoms and signs as well as newer methods of assessing congestion. Trials of treatments for central or peripheral congestion may have different inclusion criteria.

description: Algorithms and approaches for continual reinforcement learning have gained increasing attention. Much of this early progress rests on the foundations and standard practices of traditional reinforcement learning, without questioning if they are well-suited to the challenges of continual learning agents. We suggest that many core foundations of traditional RL are, in fact, antithetical to the goals of continual reinforcement learning. We enumerate four such foundations: the Markov decision process formalism, a focus on optimal policies, the expected sum of rewards as the primary evaluation metric, and episodic benchmark environments that embrace the other three foundations. Shedding such sacredly held and taught concepts is not easy. They are self-reinforcing in that each foundation depends upon and holds up the others, making it hard to rethink each in isolation. We propose an alternative set of all four foundations that are better suited to the continual learning setting. We hope to spur on others in rethinking the traditional foundations, proposing and critiquing alternatives, and developing new algorithms and approaches enabled by better-suited foundations.
