Year: 2010

description: Dieser Beitrag befasst sich mit der zunehmenden Tendenz politischer Eliten, auf die journalistische Berichterstattung und den politischen Journalismus Einfluss zu nehmen. Dabei wird gezeigt, inwieweit dadurch Handlungsspielräume im politischen Journalismus eingeschränkt werden. Untersucht werden insgesamt vier Länder, nämlich die USA, die Bundesrepublik Deutschland, Österreich und Italien. Beim diesem Vergleich stellt sich die Frage nach der Bedeutung struktureller Unterschiede angesichts der verschiedenen politischen Systeme in den untersuchten Ländern (z. B. präsidentielles vs. parlamentarische Systeme, parteien- vs. medienzentrierte Systeme). Abschließend geht es um Überlegungen zu unterschiedlichen privatrechtlich organisierten oder dualen Mediensystemen im Zusammenhang strategischer Einflussnahmen und Abwehrmaßnahmen.

description: Modern streaming services are increasingly labeling videos based on their visual or audio content. This typically augments the use of technologies such as AI and ML by allowing to use natural speech for searching by keywords and video descriptions. Prior research has successfully provided a number of solutions for speech to text, in the case of a human speech, but this article aims to investigate possible solutions to retrieve sound events based on a natural language query, and estimate how effective and accurate they are. In this study, we specifically focus on the YamNet, AlexNet, and ResNet-50 pre-trained models to automatically classify audio samples using their respective melspectrograms into a number of predefined classes. The predefined classes can represent sounds associated with actions within a video fragment. Two tests are conducted to evaluate the performance of the models on two separate problems: audio classification and intervals retrieval based on a natural language query. Results show that the benchmarked models are comparable in terms of performance, with YamNet slightly outperforming the other two models. YamNet was able to classify single fixed-size audio samples with 92.7% accuracy and 68.75% precision while its average accuracy on intervals retrieval was 71.62% and precision was 41.95%. The investigated method may be embedded into an automated event marking architecture for streaming services.

description: Jugendliche Gewaltbereitschaft wird in der medienkritischen Diskussion nicht selten auf mediale Vorbilder zurück geführt. Anhand qualitativer Daten wird zum einen gezeigt, dass das Erkennen medialer Gewalt in Sprache und Handlung bildungsabhängig ist, zum anderen, dass Jugendliche nach eigenen Angaben aus sehr unterschiedlichen Gründen zur Gewalt bereit wären – etwa, um Freunde zu verteidigen. Besonders betrachtet werden dann Jugendliche, die gern Horrorfilme anschauen. Die Untersuchung zeigt, dass die Fans von Horrorfilmen eine Rezeptionshaltung einnehmen, die zwischen Angst-Lust und Distanz oszilliert. Es interessieren hier keine identifikatorischen Aspekte, sondern Jugendliche haben Spaß an den medialen Inszenierungen des Gruseligen. Jenseits medienmoralischer Warnungen plädiert der Beitrag – unter Verweis auch auf Rezeptionstheorien der Literaturwissenschaft – dafür, distanzierten Horror-Genuss als Spielform nicht zu überbewerten und ihn auch als Ausdruck elaborierter Lese- und Medienkompetenz zu verstehen.

description: Understanding the correlation effects in unconventional topological materials, in which the fermion excitations take unusual dispersion, is an important topic in recent condensed matter physics. We study the influence of short-range four-fermion interactions on three-dimensional semi-Dirac semimetal with an unusual fermion dispersion, that is linear along two directions and quadratic along the third one. Based on renormalization group theory, we find all of 11 unstable fixed points including 5 quantum critical points, 5 bicritical points, and one tricritical point. The physical essences of the quantum critical points are determined by analyzing the susceptibility exponents for all of the source terms in particle-hole and particle-particle channels. We also verify phase diagrams of the system in the parameter space through numerically studying the flows of the four-fermion coupling parameters and behaviors of the susceptibility exponents. These results are helpful for us to understand the physical properties of candidate materials for three-dimensional semi-Dirac semimetal such as ZrTe$_{5}$.

Spectral and scattering theory for some abstract QFT Hamiltonians

Publisher: name: arXiv
Year: 2008
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: We introduce an abstract class of bosonic QFT Hamiltonians and study their spectral and scattering theories. These Hamiltonians are of the form $H=\d\G(ω)+ V$ acting on the bosonic Fock space $\G(\ch)$, where $ω$ is a massive one-particle Hamiltonian acting on $\ch$ and $V$ is a Wick polynomial $\Wick(w)$ for a kernel $w$ satisfying some decay properties at infinity. We describe the essential spectrum of $H$, prove a Mourre estimate outside a set of thresholds and prove the existence of asymptotic fields. Our main result is the {\em asymptotic completeness} of the scattering theory, which means that the CCR representations given by the asymptotic fields are of Fock type, with the asymptotic vacua equal to the bound states of $H$. As a consequence $H$ is unitarily equivalent to a collection of second quantized Hamiltonians.

description: The usage of different technologies and smart devices helps people to get medical services remotely for multiple benefits. Thus, critical and sensitive data is exchanged between a user and a doctor. When health data is transmitted over a common channel, it becomes essential to preserve various privacy and security properties in the system. Further, the number of users for remote services is increasing day-by-day exponentially, and thus, it is not adequate to deal with all users using the one server due to the verification overhead, server failure, and scalability issues. Thus, researchers proposed various authentication protocols for multi-server architecture, but most of them are vulnerable to different security attacks and require high computational resources during the implementation. To Tackle privacy and security issues using less computational resources, we propose a privacy-preserving mutual authentication and key agreement protocol for a multi-server healthcare system. We discuss the proposed scheme's security analysis and performance results to understand its security strengths and the computational resource requirement, respectively. Further, we do the comparison of security and performance results with recent relevant authentication protocols.

description: This study aims to determine the demographic, epidemiologic, and clinical characteristics of COVID-19 cases that are highly susceptible to COVID-19 infection, with longer hospitalization and at higher risk of mortality and to provide insights that may be useful to assess the vaccination priority program and allocate hospital resources. Methods that were used include descriptive statistics, nonparametric analysis, and survival analysis. Results of the study reveal that women are more susceptible to infection while men are at risk of longer hospitalization and higher mortality. Significant risk factors to COVID-19 mortality are older age, male sex, difficulty breathing, and comorbidities like hypertension and diabetes. Patients with these combined symptoms should be considered for admission to the COVID-19 facility for proper management and care. Also, there is a significant delay in the testing and diagnosis of those who died, implying that timeliness in the testing and diagnosis of patients is crucial in patient survival.

description: The accuracy of the classical heat conduction model, known as Fourier's law, is highly questioned, dealing with the micro and nanosystems and biological tissues. In other words, the results obtained from the classical equations deviate from the available experimental data. It means that the continuum heat diffusion equation is insufficient and inappropriate for modeling heat transport in these cases. There are several techniques for modeling non-Fourier heat conduction. In the present paper, we place our focus on the dual-phase-lag (DPL) approach. The DPL model, as a popular modification of Fourier's law, has already been utilized in numerous situations, such as simulating ultrafast laser heating and heat conduction in carbon nanotubes. There has been a sharp increase in research on non-Fourier heat conduction in recent years. Several studies have been performed in the fields of thermoelasticity, thermodynamics, transistor modeling, and bioheat transport. This review presents the most recent non-Fourier bioheat conduction works and the related thermodynamics background. The various mathematical tools, modeling different thermal therapies, and relevant criticisms and disputes are discussed. Finally, the novel and other possible studies are also presented to provide a better overview, and the roadmap to the future research and challenges ahead is drawn up.

description: We study higher curvature corrections to the scalar spectral index, the tensor spectral index, the tensor-to-scalar ratio, and the polarization of gravitational waves. We find that the higher curvature corrections can not be negligible in the dynamics of the scalar field, although they are energetically negligible. Indeed, it turns out that the tensor-to-scalar ratio could be enhanced and the tensor spectral index could be blue due to the Gauss-Bonnet term. We estimate the degree of circular polarization of gravitational waves generated during the slow-roll inflation. We argue that the circular polarization can be observable with the help both of the Gauss-Bonnet and parity violating terms. We also present several examples to reveal observational implications of higher curvature corrections for chaotic inflationary models.

description: Cardiac segmentation of atriums, ventricles, and myocardium in computed tomography (CT) images is an important first-line task for presymptomatic cardiovascular disease diagnosis. In several recent studies, deep learning models have shown significant breakthroughs in medical image segmentation tasks. Unlike other organs such as the lungs and liver, the cardiac organ consists of multiple substructures, i.e., ventricles, atriums, aortas, arteries, veins, and myocardium. These cardiac substructures are proximate to each other and have indiscernible boundaries (i.e., homogeneous intensity values), making it difficult for the segmentation network focus on the boundaries between the substructures. In this paper, to improve the segmentation accuracy between proximate organs, we introduce a novel model to exploit shape and boundary-aware features. We primarily propose a shape-aware attention module, that exploits distance regression, which can guide the model to focus on the edges between substructures so that it can outperform the conventional contour-based attention method. In the experiments, we used the Multi-Modality Whole Heart Segmentation dataset that has 20 CT cardiac images for training and validation, and 40 CT cardiac images for testing. The experimental results show that the proposed network produces more accurate results than state-of-the-art networks by improving the Dice similarity coefficient score by 4.97%. Our proposed shape-aware contour attention mechanism demonstrates that distance transformation and boundary features improve the actual attention map to strengthen the responses in the boundary area. Moreover, our proposed method significantly reduces the false-positive responses of the final output, resulting in accurate segmentation.

description: By defining a spatially varying replica overlap parameter for a supercooled liquid referenced to an ensemble of fiducial liquid state configurations we explicitly construct a constrained replica free energy functional that maps directly onto an Ising Hamiltonian with both random fields and random interactions whose statistics depend on liquid structure. Renormalization group results for random magnets when combined with these statistics for the Lennard-Jones glass suggest that discontinuous replica symmetry breaking would occur if a liquid with short range interactions could be equilibrated at a sufficiently low temperature where its mean field configurational entropy would vanish, even though the system strictly retains a finite configurational entropy.
Cold plasma treatment of seeds: deciphering the role of contact surfaces through multiple exposures, randomizing and stirring

Year: 2021
Subjects: subject: Plasma Physics (physics.plasm-ph)

description: Cold plasma technologies are an efficient approach to improve the germination properties of seeds, especially in a stacking configuration within a dielectric barrier device. In such dry atmospheric plasma priming process, we show that a He-N2 plasma treatment of 20 min can reduce the median germination time of lentil seeds from 1420 min to 1145 minutes, ie a gain in vigor of 275 min (or +19.4 %). Considering that this result depends on the plasma-seed interaction and therefore on the contact surfaces between the seeds and the plasma, a topographic modeling of a 100 seeds-stack is performed in the dielectric barrier device. This model drives to the distinction between the seed-seed contact surfaces (276 contacts standing for a total area of 230.6 mm2) and the seed-wall contact surfaces (134 contacts standing for a total area of 105.9 mm2). After a single plasma treatment, the outer envelope of each seed is 92% exposed to plasma: a value high enough to support the relevance of the plasma process but which also opens the way to process optimizations. In this outlook, we propose to replace the single 20-minute plasma treatment by a "plasma sequence", ie a succession of shorter plasma treatments whose total duration remains 20 min. Between two successive plasma treatments, the seeds can follow either a trapping procedure (seeds in same positions and orientations) or a randomizing procedure (seeds in same positions but reoriented) or a stirring procedure (seeds vigorously shaken). A sequence of 10 plasma treatments (upon 2 min) separated by short stirring procedures leads to a gain in vigor as high as 405 min vs 275 min for a single plasma treatment of 20 min. We propose to understand these results by correlating the gain in vigor with the water uptake of the seeds and the wettability state of their coating.

CaFe2As2 crystalizes in the ThCr2Si2 structure with lattice parameters a = 3.907(4) A and c = 11.69(2) A. Magnetic susceptibility, resistivity, and heat capacity all show a first order phase transition at T_0 171 K. The magnetic susceptibility is nearly isotropic from 2 K to 350 K. The heat capacity data gives a Sommerfeld coefficient of 8.2 +- 0.3 mJ/molK2, and does not reveal any evidence for the presence of high frequency (> 300 K) optical phonon modes. The Hall coefficient is negative below the transition indicating dominant n-type carriers.

description: Quantum simulation represents the most promising quantum application to demonstrate quantum advantage on near-term noisy intermediate-scale quantum (NISQ) computers, yet available quantum simulation algorithms are prone to errors and thus difficult to be realized. Herein, we propose a novel scheme to utilize intrinsic gate errors of NISQ devices to enable controllable simulation of open quantum system dynamics without ancillary qubits or explicit bath engineering, thus turning unwanted quantum noises into useful quantum resources. Specifically, we simulate energy transfer process in a photosynthetic dimer system on IBM-Q cloud. By employing designed decoherence-inducing gates, we show that quantum dissipative dynamics can be simulated efficiently across coherent-to-incoherent regimes with results comparable to those of the numerically-exact classical method. Moreover, we demonstrate a calibration routine that enables consistent and predictive simulations of open-quantum system dynamics in the intermediate coupling regime. This work provides a new direction for quantum advantage in the NISQ era.

description: Four different finite element level-set (FE-LS) formulations are compared for the modeling of grain growth in the context of polycrystalline structures and, moreover, two of them are presented for the first time using anisotropic grain boundary (GB) energy and mobility. Mean values and distributions are compared using the four formulations. First, we present the strong and weak formulations for the different models and the crystallographic parameters used at the mesoscopic scale. Second, some Grim Reaper analytical cases are presented and compared with the simulation results, here the evolutions of individual multiple junctions are followed. Additionally, large scale simulations are presented. Anisotropic GB energy and mobility are respectively defined as functions of the misorientation/inclination and disorientation. The evolution of the disorientation distribution function (DDF) is computed and its evolution is in accordance with prior works. We found that the formulation called "Anisotropic" is the more physical one but it could be replaced at the mesoscopic scale by an Isotropic formulation for simple microstructures presenting an initial Mackenzie-type DDF.

description: We present a method for the direct extraction of rational contributions to one-loop scattering amplitudes, missed by standard four-dimensional unitarity techniques. We use generalised unitarity in $D=4-2\e$ dimensions to write the loop amplitudes in terms of products of massive tree amplitudes. We find that the rational terms in $4-2\e$ dimensions can be determined from quadruple, triple and double cuts without the need for independent pentagon contributions using a massive integral basis. The additional mass-dependent integral coefficients may then be extracted from the large mass limit which can be performed analytically or numerically. We check the method by computing the rational parts of all gluon helicity amplitudes with up to six external legs. We also present a simple application to amplitudes with external massless fermions.

Artificial Horizon. Blind Flight in the History of Virtual Reality
Creators: name: Roberts, Ivy
Publisher: name: International Journal on Stereo & Immersive Media
Year: 2022

description: Histories of virtual reality (VR) usually place its origins in computing. But this can be pushed back even further by considering early experiments in flight, principally in the endeavour to fly by instrument, that took place in the late 1920s and throughout the 1930s. This essay positions blind flight in the history of virtual reality and other immersive media in order to understand what sensory deprivation has to do with proprioception. Deprived of visual and aural senses, pilots were taught to reorient their perception of space using the artificial horizon as their guide. This essay uses the metaphor of the artificial horizon to discuss the relationship between sensory deprivation and sensory overload, both of which disturb the internal process that makes proprioception possible. Applying the method of media archeology places this study among others that have sought to historicise contemporary immersive media in unique ways, often with unexpected outcomes.

description: Algebraic hyperbolicity serves as a bridge between differential geometry and algebraic geometry. Generally, it is difficult to show that a given projective variety is algebraically hyperbolic. However, it was established recently that a very general surface of degree at least five in projective space is algebraically hyperbolic. We are interested in generalizing the study of surfaces in projective space to surfaces in smooth projective toric threefolds with Picard rank 2 or 3. Following Kleinschmidt and Batyrev, we explore the combinatorial description of smooth projective toric threefolds with Picard rank 2 and 3. We then use Haase and Ilten's method of finding algebraically hyperbolic surfaces in toric threefolds. As a result, we determine many algebraically hyperbolic surfaces in each of these varieties.

description: We consider $n\times n$ real symmetric and Hermitian Wigner random matrices $n^{-1/2}W$ with independent (modulo symmetry condition) entries and the (null) sample covariance matrices $n^{-1}X^*X$ with independent entries of $m\times n$ matrix $X$. Assuming first that the 4th cumulant (excess) $κ_4$ of entries of $W$ and $X$ is zero and that their 4th moments satisfy a Lindeberg type condition, we prove that linear statistics of eigenvalues of the above matrices satisfy the central limit theorem (CLT) as $n\to\infty$, $m\to\infty$, $m/n\to c\in[0,\infty)$ with the same variance as for Gaussian matrices if the test functions of statistics are smooth enough (essentially of the class $\mathbf{C}^5$). This is done by using a simple ``interpolation trick'' from the known results for the Gaussian matrices and the integration by parts, presented in the form of certain differentiation formulas. Then, by using a more elaborated version of the techniques, we prove the CLT in the case of nonzero excess of entries again for essentially $\mathbb{C}^5$ test function. Here the variance of statistics contains an additional term proportional to $κ_4$. The proofs of all limit theorems follow essentially the same scheme.

of IT with International Migration (IM) and Foreign Direct Investments (FDI). In both cases the procedure used is to first approach the problem in a multiple-networks
perspective and than deepen the analysis by using ad hoc econometrics techniques. With respect to IM, a general positive correlation with IT is highlighted and
product categories for which this effect is stronger are identified and cross-checked with previous classifications. Next, employing spatial econometric techniques and
proposing a new way to define country neighbors based on the most intense IM flows, direct/indirect network effects are studied and a stronger competitive effect of
third country migrants is identified for a specific product class. In the case of FDI, first correlations between the two networks are identified, highlighting how
they can be mostly explained by countries economic/demographic size and geographical distance. Then, using the Heckman selection model with a gravity equation,
(non-linear) components arising from distance, position in the Global Supply Chain and presence of Regional Trade Agreements are studied. Finally, it is shown
how IT and FDI correlation changes with sectors: they are complements in manufacturing, but substitutes in services.

description: Nonlinear topological photonic and phononic systems have recently aroused intense interests in exploring new phenomena that have no counterparts in electronic systems. The squeezed bosonic interaction in these systems is particularly interesting, because it can modify the vacuum fluctuations of topological states, drive them into instabilities, and lead to topological parametric lasers. However, these phenomena remain experimentally elusive because of limited nonlinearities in most existing topological bosonic systems. Here, we experimentally realized topological parametric lasers based on nonlinear nanoelectromechanical Dirac-vortex cavities with strong squeezed interaction. Specifically, we parametrically drove the Dirac-vortex cavities to provide phase-sensitive amplification for topological phonons, and observed phonon lasing above the threshold. Additionally, we confirmed that the lasing frequency is robust against fabrication disorders and that the free spectral range defies the universal inverse scaling law with increased cavity size, which benefit the realization of large-area single-mode lasers. Our results represent an important advance in experimental investigations of topological physics with large bosonic nonlinearities and parametric gain.
Downsizing revised: Star formation timescales for elliptical galaxies with an environment-dependent IMF and number of SNIa

description: Previous studies of the stellar mean metallicity and [Mg/Fe] values of massive elliptical (E)~galaxies suggest that their stars were formed in a very short timescale which cannot be reconciled with estimates from stellar population synthesis (SPS) studies and with hierarchical-assembly. Applying the previously developed chemical evolution code, GalIMF, which allows an environment-dependent stellar initial mass function (IMF) to be applied in the integrated galaxy initial mass function (IGIMF) theory instead of an invariant canonical IMF, the star formation timescales (SFT) of E galaxies are re-evaluated. The code's uniqueness lies in it allowing the galaxy-wide IMF and associated chemical enrichment to evolve as the physical conditions in the galaxy change. The calculated SFTs become consistent with the independent SPS results if the number of type Ia supernovae (SNIa) per unit stellar mass increases for more massive E~galaxies. This is a natural outcome of galaxies with higher star-formation rates producing more massive star clusters, spawning a larger number of SNIa progenitors per star. The calculations show E~galaxies with a stellar mass $\approx 10^{9.5} M_\odot$ to have had the longest mean SFTs of $\approx2\,$Gyr. The bulk of more massive E~galaxies were formed faster (SFT$\,\approx 1\,$Gyr) leading to domination by M~dwarf stars and larger dynamical mass-to-light ratios as observed, while lower-mass galaxies tend to lose their gas supply more easily due to their shallower potential and therefore also have similarly-short mean SFTs. This work achieves, for the first time, consistency of the SFTs for early-type galaxies between chemical-enrichment and SPS modelling and leads to an improved understanding of how the star formation environment may affect the total number of SNIa per unit stellar mass formed.

Some physico-chemical characteristics of dietary fiber

description: Particle size distribution, chemical composition, water binding and water holding capacities, microstructure, and Theological properties of dietary fiber residues of American Association of Cereal Chemists certified food grade wheat bran, apple mesocarp and pomace, cabbage and carrot (edible portion) were determined. The semiauto-mated Tecator FiberTec system and the extraction techniques of D.A.T. Southgate and of P.J. Van Soest were used for digestion and collection of dietary fiber residues. The ability of various fiber residues, of different size ranges, to interact with water was assessed by two methods. Water holding capacity was estimated as the amount of water remaining within a hydrated sample subjected to compaction by a standard centrifugation technique. This method closely resembles conditions in the body, but is an inaccurate technique, since supernatant water is not easily separated from the sample. A new method, called filtrafugation, was developed to obtain information on water binding which Mas defined as the amount of water adhering to the fiber particle when water is allowed to drain from the sample during centrifugation. The amounts of water remaining with the fiber in centrifugation and filtrafugation tests differed significantly for each fiber source, the difference being the water held within the fiber matrix interstices. Although the fruit and vegetable fiber sources had greater water binding and holding capacities on a dried weight basis, wheat bran held and bound more water on a fresh weight basis because of higher fiber content and percent dry matter. Scanning electron microscopy of the different fiber sources and their fiber residues confirmed the progressively erosive action of the solvent extraction treatments and elucidated subsequent differences in water binding and holding capacities. Since bran is a senescent and lignified plant tissue, in vitro digestion changed the particle appearance, but the structural matrix, and the water binding and holding capacities were maintained throughout. Micrographs of the fruit and vegetable fiber sources and the fiber residues confirmed that the initial structures were able to bind and hold large amounts of water but with digestion the delicate structures were totally disrupted, thus providing a weak compact matrix characterized by low water binding and holding capacities. Dispersions of the fiber residues were evaluated viscometrically at human body temperature in order to elucidate their behavior in fluid systems. When aqueous dispersions were prepared at low concentrations the solid materials gradually settled except for the apple pomace dispersions. Steady shear flow behavior studies using 60% w/w sucrose solution as the continuous phase revealed large viscosity increases at higher concentrations of the dietary fiber residue.

description: We report on the calculation of NNLO corrections to the 3-jet cross section and related event shape distributions in electron-positron annihilation. The corrections are sizable for all variables, however the magnitude of the corrections is substantially different for different observables. We observe that inclusion of the NNLO corrections yields a considerably better agreement between theory and experimental data both in shape and normalization of the event shape distributions in the region where the perturbative result is expected to hold. A new extraction of $α_{s}$ using the event shape variables up to NNLO yields a considerably better consistency between the observables indicating a stabilization of the perturbative corrections at this order.

description: In a variety of contexts, involving execution of software or hardware manipulating sensitive data, one would like that public observables
do not leak information that should be kept secret. Since it is practically impossible to avoid leakage entirely, there is a growing interest in the quantitative
aspects of information flow analysis. This is also related to privacy, that is to protection of sensitive information concerning individuals. In this context, we
first study methods to measure the average amount of leakage due to system execution, quantifying the possibility of inferring the secret information from observables.
We assume an attacker that can make a single guess after observing a certain number of independent executions of the program. We study the asymptotic behaviour of
information leakage and the dichotomy between protection of the whole secret and of a property of the secret. An average measure of leakage may not be adequate
when privacy of individuals is at stake. To study this issue, we introduce a strong semantic notion of security, that expresses absence of any privacy breach above
a given level of seriousness, irrespective of any background information. We then analyze this notion according to two dimensions: worst vs. average case, single vs. repeated
observations, and clarify its relation to differential privacy. Finally, motivated by the complexity of exact computation of quantitative information leakage,
we study statistical approaches to its estimation, when only a black-box access to the system is provided, and little is known about the input generation mechanism.
