title: Psychische Krankheiten als gesellschaftliches Konstrukt - Entwicklungen, Tendenzen und Strategien ihrer Darstellung im Film nach 2000
Creators: name: Markovic, Melanie
Year: 2017

description: Das Thema der Dissertation beschäftigt sich mit der Fragestellung inwieweit psychische Erkrankungen ein gesellschaftliches Konstrukt sind, ob der Film als eigenes System wahrgenommen werden kann und ob eine Filmanalyse anhand von Leitdifferenzen möglich ist. Folgende Fragestellungen wurden behandelt: Wie konstruiert die Gesellschaft psychische Erkrankung und wie ist der Umgang damit? Welcher gesellschaftlich relevante Diskurs ergibt sich daraus? Wie kann die Systemtheorie und der Konstruktivismus die audio-visuelle Kommunikationsmöglichkeit als Grundlage für ein neues Forschungsfeld nutzbar machen? Und kann die Systemtheorie und Filmwissenschaft auf das Phänomen Film angewendet werden? Ziel der entwickelten Methode ist eine Systemische Filmanalyse zu schaffen, die es ermöglichen sozial konstruierte Wirklichkeiten zu untersuchen. Hier gilt es einen Unterschied zu schaffen zur klassischen Filmanalyse, die den Film nicht anhand von Ästhetik und Gestaltung untersucht, sondern anhand von Systemen und dessen Leitdifferenzen. In der vorliegenden Arbeit ist es gelungen einen Prototyp zu einer andersartigen, neuen Filmanalyse zu erschaffen, nämlich die einer Systemischen Filmanalyse.
description: The topic of the dissertation deals with the extent to which mental disorders are a social construct, whether the film can be perceived as a separate system, and whether film analysis is possible on the basis of lead differences. The following questions were dealt with: How does society construct mental illness and how is it treated? What is the relevant social discourse? How can system theory and constructivism make the audio-visual communication possible as a basis for a new field of research? And can system theory and film science be applied to the film phenomenon? The aim of the developed method is to create a systemic film analysis, which allows to investigate socially constructed realities. Here we have to create a difference to the classical film analysis, which does not examine the film by means of aesthetics and design, but by systems and its lead differences. In this work we have succeeded in creating a prototype for a different, new film analysis, namely a Systemic Film Analysis.

description: Objective: Improving geographical access remains a key issue in determining the sufficiency of regional medical resources during health policy design. However, patient choices can be the result of the complex interactivity of various factors. The aim of this study is to propose a deep neural network approach to model the complex decision of patient choice in travel distance to access care, which is an important indicator for policymaking in allocating resources. Method: We used the 4-year nationwide insurance data of Taiwan and accumulated the possible features discussed in earlier literature. This study proposes the use of a convolutional neural network (CNN)-based framework to make predictions. The model performance was tested against other machine learning methods. The proposed framework was further interpreted using Integrated Gradients (IG) to analyze the feature weights. Results: We successfully demonstrated the effectiveness of using a CNN-based framework to predict the travel distance of patients, achieving an accuracy of 0.968, AUC of 0.969, sensitivity of 0.960, and specificity of 0.989. The CNN-based framework outperformed all other methods. In this research, the IG weights are potentially explainable; however, the relationship does not correspond to known indicators in public health, similar to common consensus. Conclusions: Our results demonstrate the feasibility of the deep learning-based travel distance prediction model. It has the potential to guide policymaking in resource allocation.

description: We carry out a population study of magnetized radio filaments in the Galactic center using MeerKAT data by focusing on the spacing between the filaments that are grouped. The morphology of a sample of 43 groupings containing 174 magnetized radio filaments are presented. Many grouped filaments show harp-like, fragmented cometary tail-like, or loop-like structures in contrast to many straight filaments running mainly perpendicular to the Galactic plane. There are many striking examples of a single filament splitting into two prongs at a junction, suggestive of a flow of plasma along the filaments. Spatial variations in spectral index, brightness, bending and sharpening along the filaments indicate that they are evolving on a 10^{5-6}-year time scale. The mean spacings between parallel filaments in a given grouping peaks at $\sim16''$. We argue by modeling that the filaments in a grouping all lie on the same plane and that the groupings are isotropically oriented in 3D space. One candidate for the origin of filamentation is interaction with an obstacle, which could be a compact radio source, before a filament splits and bends into multiple filaments. In this picture, the obstacle or sets the length scale of the separation between the filaments. Another possibility is synchrotron cooling instability occurring in cometary tails formed as a result of the interaction of cosmic-ray driven Galactic center outflow with obstacles such as stellar winds. In this picture, the mean spacing and the mean width of the filaments are expected to be a fraction of a parsec, consistent with observed spacing.

description: We consider several well-known f(R) cosmological models and constrain their parameters, namely the deviation parameter b and the cosmological parameters Ω_m and h. We first obtain analytical approximations for the Hubble rate H(z) and the luminosity distance d_L(z) in terms of these parameters, and then test these against the observational expansion rate derived from cosmic chronometers and the distance modulus in the HII galaxy Hubble diagram, obtained in a model-independent way using Gaussian Processes (GP). We first optimize the models based solely on the cosmic chronometers and then repeat this process with a joint analysis using both the cosmic chronometers and HII galaxies.

Linearity: galaxy formation encounters an unanticipated empirical relation

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Measurements from galaxies spanning a broad range of morphology reveal a linear scaling of enclosed dark to luminous mass that is not anticipated by standard galaxy formation cosmology. The linear scaling is found to extend from the inner galactic region to the outermost data point. Uncertainties in the linear relation are narrow, with rms = 0.31 and σ = 0.31. It is unclear what would produce this linearity of enclosed dark to luminous mass. Baryonic processes are challenged to account for the linear scaling, and no dark matter candidate possesses a property that would result in a linear relation. The linear scaling may indicate new dark matter candidates, or an astrophysical process beyond the standard galaxy formation theory.

description: Objectivos: Estudar a prevalência, factores de risco, evolução clínica e abordagem terapêutica da sífilis congénita em recém-nascidos (RN) de risco, nascidos numa maternidade de referência com apoio perinatal diferenciado.

Método: Realizou-se um estudo transversal para cálculo de prevalência à nascença de sífilis congénita, entre Janeiro de 1993 e Dezembro de 2004, através de recolha de dados registados nos processos clínicos das mães e respectivos RN. De acordo com os critérios definidos pelo Centers for Disease Control and Prevention (CDC) em 1989, os RN filhos de mãe com VDRL e/ou TPHA positivo foram divididos em três grupos de risco.

Resultados: Foram identificados 467 recém-nascidos, verificando-se que a prevalência de risco de sífilis congénita à nascença se tem mantido ao longo dos anos (5,6‰). Amaioria dos recém-nascidos (65%) enquadra-se no grupo de maior risco. Dezanove RN (4%) apresentaram sífilis congénita sintomática no nascimento, a maioria pertencente ao grupo de maior risco. Outros factores de risco encontrados foram a gravidez não-vigiada, em 30% das mães, toxicodependência em 9%, coinfecção por vírus da hepatite B em 5%, por vírus da hepatite C em 4,7% e por vírus de imunodeficiência humana em 3,4% dos casos. Em alguns casos existia mais do que um factor de risco associado.

Conclusões: Verificou-se que a prevalência de risco de sífilis congénita não sofreu grandes variações ao longo dos doze anos, pelo que a sífilis continua a constituir um problema de Saúde Pública em Portugal, com custos económicos e sociais.

description: In terrestrial laboratory with existing accelerators, the maximum multinucleon system produced so far is limited to that with total nucleon number being less than the sum of two colliding nuclei. Such situation may hinder our studies on the properties of nuclear many-body system. Here a way of producing large multinucleon system via multi-nucleus collision device Collider Plus in terrestrial laboratory is proposed. It is shown that large chunk of nucleonic matter can be produced through nuclear ternary fusion reactions at lower beam energies and also large block of dense matter can be formed via ternary collisions of heavy nuclei at intermediate energies. These investigations may shed lights on the studies of the synthesis of superheavy elements and the properties of bulk superdense nuclear matter.

description: We study the parameter space of magnetically charged AdS$_2\times\mathbb{WCP}^{1}_{[n_-,n_+]}$ solutions in 4d U$(1)^4$ gauged STU supergravity. We show that both \emph{twist} and \emph{anti-twist} solutions are realised and give constraints for their existence in terms of the magnetic charges of the solution. We provide infinite families of both classes of solution in terms of their magnetic charges and weights of the orbifold. As a byproduct of our analysis we obtain a closed form expression for the free-energy of the 4-charge magnetic solution in terms of the magnetic charges and weights $n_{\pm}$. We also show that the AdS$_2$ solution is the near-horizon of an asymptotically AdS$_4$ black hole which can be found in the literature.

description: Parameter adaptation, that is the capability to automatically adjust an algorithm's hyperparameters depending on the problem being faced, is one of the main trends in evolutionary computation applied to numerical optimization. While several handcrafted adaptation policies have been proposed over the years to address this problem, only few attempts have been done so far at applying machine learning to learn such policies. Here, we introduce a general-purpose framework for performing parameter adaptation in continuous-domain metaheuristics based on state-of-the-art reinforcement learning algorithms. We demonstrate the applicability of this framework on two algorithms, namely Covariance Matrix Adaptation Evolution Strategies (CMA-ES) and Differential Evolution (DE), for which we learn, respectively, adaptation policies for the step-size (for CMA-ES), and the scale factor and crossover rate (for DE). We train these policies on a set of 46 benchmark functions at different dimensionalities, with various inputs to the policies, in two settings: one policy per function, and one global policy for all functions. Compared, respectively, to the Cumulative Step-size Adaptation (CSA) policy and to two well-known adaptive DE variants (iDE and jDE), our policies are able to produce competitive results in the majority of cases, especially in the case of DE.

description: As if it has become a consensus that the slope of the granular heap is straight, and from that, an angle of repose is defined. However, closer inspection shows that the slopes are not truly straight, instead, more often they have convex shapes, although with small convexity. Similar curvature is observed on the sand dunes' surfaces. We derive equations together with experiments on 10 types of granular materials to show that, in general, the slope of the granular heap is convex while the straight slope is a critical state that rarely occurs. The angle of repose is allowed to vary within a narrow range around a critical value. If the angle of repose is slightly greater (smaller) than the critical value, the slope is convex (concave). The model also answers why the surfaces of granular heaps, including sand dunes, are more often convex rather than concave or straight, and advocate the simultaneous estimation of the coefficient of friction on the grain and the type of packing in the heap. The results might open new understandings related to granular material properties as well as sand transport and geological records in several deserts.

description: Several hundred gamma-ray burst (GRB) redshifts have been determined to date. One of the other important properties-besides the distance-of the GRBs is the duration of the burst. In this paper, we analyse these two important quantities of the phenomena. In this paper, we map the two-dimensional distribution and explore some suspicious areas. As it is well known that the short GRBs are closer than the others, we search for parts in the Universe where the GRB duration is different from the others. We also analyse whether there are any ranges in the duration where the redshifts differ. We find some suspicious areas, however, no other significant region was found than the short GRB region.

description: Cells can withstand hostile environmental conditions manifest as large mechanical forces such as pressure gradients and/or shear stresses by dynamically changing their shape. Such conditions are realized in the Schlemm's canal of the eye where endothelial cells that cover the inner vessel wall are subjected to the hydrodynamic pressure gradients exerted by the aqueous humor outflow. These cells form fluid-filled dynamic outpouchings of their basal membrane called \textit{giant vacuoles}. The inverse of giant vacuoles are reminiscent of cellular blebs, extracellular cytoplasmic protrusions triggered by local temporary disruption of the contractile actomyosin cortex. Inverse blebbing has been first observed experimentally during sprouting angiogenesis, but its underlying physical mechanisms are poorly understood. Here, we identify giant vacuole formation as inverse blebbing and formulate a biophysical model of this process. Our model elucidates how cell membrane mechanical properties affect the morphology and dynamics of giant vacuoles and predicts coarsening akin to Ostwald ripening between multiple invaginating vacuoles. Our results are in qualitative agreement with observations from the formation of giant vacuoles during perfusion experiments. Our model not only elucidates the biophysical mechanisms driving inverse blebbing and giant vacuole dynamics, but also identifies universal features of the cellular response to pressure loads that are relevant to many experimental contexts.
The mathematics of burger flipping

description: What is the most effective way to grill food? Timing is everything, since only one surface is exposed to heat at a given time. Should we flip only once, or many times? We present a simple model of cooking by flipping, and some interesting observations emerge. The rate of cooking depends on the spectrum of a linear operator, and on the fixed point of a map. If the system has symmetric thermal properties, the rate of cooking becomes independent of the sequence of flips, as long as the last point to be cooked is the midpoint. After numerical optimization, the flipping intervals become roughly equal in duration as their number is increased, though the final interval is significantly longer. We find that the optimal improvement in cooking time, given an arbitrary number of flips, is about 29% over a single flip. This toy problem has some characteristics reminiscent of turbulent thermal convection, such as a uniform average interior temperature with boundary layers.

description: Most general-purpose classification methods, such as support-vector machine (SVM) and random forest (RF), fail to account for an unusual characteristic of astronomical data: known measurement error uncertainties. In astronomical data, this information is often given in the data but discarded because popular machine learning classifiers cannot incorporate it. We propose a simulation-based approach that incorporates heteroscedastic measurement error into existing classification method to better quantify uncertainty in classification. The proposed method first simulates perturbed realizations of the data from a Bayesian posterior predictive distribution of a Gaussian measurement error model. Then, a chosen classifier is fit to each simulation. The variation across the simulations naturally reflects the uncertainty propagated from the measurement errors in both labeled and unlabeled data sets. We demonstrate the use of this approach via two numerical studies. The first is a thorough simulation study applying the proposed procedure to SVM and RF, which are well-known hard and soft classifiers, respectively. The second study is a realistic classification problem of identifying high-$z$ $(2.9 \leq z \leq 5.1)$ quasar candidates from photometric data. The data are from merged catalogs of the Sloan Digital Sky Survey, the $Spitzer$ IRAC Equatorial Survey, and the $Spitzer$-HETDEX Exploratory Large-Area Survey. The proposed approach reveals that out of 11,847 high-$z$ quasar candidates identified by a random forest without incorporating measurement error, 3,146 are potential misclassifications with measurement error. Additionally, out of $1.85$ million objects not identified as high-$z$ quasars without measurement error, 936 can be considered new candidates with measurement error.

description: Due to the recent groundbreaking developmentsof nanotechnologies,it became possible to create intrinsically quantum systems able to serve as high-directional antennas in THz, infrared and optical ranges. Actually, the quantum antennas,as devices shaping light on thelevel of single quanta,havealreadybecomethe key elements in nanooptics and nanoelectronics. The quantum antennas are actively researched for possible implementations in quantum communications, quantum imaging and sensing,andenergy harvesting. However, the design and optimization of these emitting/receivingdevices arestill rather undevelopedin comparisonwith the well-known methods for conventional radio-frequency antennas. This review provides a discussion of the recent achievements in the concept of the quantum antenna as an open quantum systememitting via interaction with a photonic reservoir. We focuson bridging the gap between quantum antennas and their macroscopic classical analogues. We also discuss the ways of quantum-antennaimplementation for different configurations basedon such materials, as plasmonic metals, carbon nanotubes, and semiconductor quantum dots.

Loop induced $h \rightarrow γγ, Zγ, gg $ decays in 3-Higgs doublet models

description: In this paper, we analyze the loop induced decays of neutral Higgs boson $ h $ into pairs of photons, gluons, and Z$ γ$ in 3-Higgs Doublet Models (3HDMs), where all the doublets have non-zero vacuum expectation values. In the 3HDM, there are contributions to these decays from loops of charged scalars $ H^{\pm}_{1,2} $ that are not present in the Standard Model. We find an enhancement in the channel $ h\rightarrow Zγ$ with respect to the Standard Model prediction in some parameter region while respecting constraints from the measurements of $ h\rightarrow γγ$ at the LHC. The charged Higgs bosons $ H^{\pm}_{1,2} $ lead to the enhancement of $ Zγ$ decay mode in some part of the parameter space of the 3HDM. Then, we discuss the correlations between the decay modes $ h\rightarrow Zγ$ and $ h\rightarrow γγ$. Moreover, we study Type-I and Type-Z of 3HDMs and find that these types of 3HDMs can be distinguished via only the gluonic decays, since the contributions of the $ H^{\pm}_{1,2} $ loops are dominant to those of fermion loops. We also investigate the effects of the model parameters on these loop induced decays. As an interesting phenomenological consequence, the 3HDM is dominantly governed by the parameters: two ratios of vacuum expectation values (VEVs); $ \tanγ,~\tanβ$ and the mixing angles of the CP-even Higgs bosons, $ α_{1,2}~ \text{and}~θ$.

description: Cyberbullying (CBB) is an emerging social concern that has harmful effects on the life satisfaction of students and their relatives. This study aimed to examine how family function, resilience, and anxiety mediate the link between childhood maltreatment (CM) and CBB victimization/perpetration among Iranian students. We conducted a cross-sectional study in March 2022 with 403 students (75 males, 328 females) aged 18 to 50. Participants completed an online questionnaire encompassing the Child Abuse Self-Report Scale, Cyberbullying and Online Aggression Scale, Connor-Davidson Resilience Scale, Family Assessment Device (FAD), and State-Trait Anxiety Inventory (STAI). We found that CM correlated with CBB victimization/perpetration. The mediation analysis showed that family function fully mediates the relationship between CM and CBB victimization/perpetration. Also, poor family function could raise anxiety and the risk of CBB victimization/perpetration. Moreover, the reduced family function might harm individuals’ resilience, and lower resilience might increase the likelihood of becoming a victim of CBB through anxiety mediation. Overall, our research underscores the family's pivotal role in ensuring cyber safety and preventing CBB involvement of its members, and it should be considered in intervention programs.

Latest Long-baseline 3-flavor Neutrino Oscillation Results from the NOvA Experiment
Creators: name: Sutton, Andrew
Publisher: name: Zenodo
Year: 2022

description: NOvA is a long-baseline neutrino experiment based at the Fermi National Accelerator Laboratory, USA. Utilizing two functionally-identical tracking calorimeters placed 809 km apart, NOvA observes the appearance of electron (anti)neutrinos and the disappearance of muon (anti)neutrinos in the muon (anti)neutrino-dominated NuMI beam. By observing these neutrino oscillations along with their antineutrino counterparts, NOvA is probing outstanding questions in neutrino physics including the neutrino mass ordering, leptonic CP violation parameterized by the phase δCP, the larger neutrino mass splitting Δm232, and the mixing angle θ23. Here, we present the most recent 3-flavor neutrino oscillation results from NOvA, which include about 50% more neutrino-mode data, improved reconstruction algorithms, and a new simulation.

description: The famous scientist Hermann von Helmholtz was born 200 years ago. Many complex physical wave phenomena in engineering can effectively be described using one or a set of equations named after him: the Helmholtz equation. Although this has been known for a long time from a theoretical point of view, the actual numerical implementation has often been hindered by divergence free and/or curl free constraints. There is further a need for a numerical method that is accurate, reliable and takes into account radiation conditions at infinity. The classical boundary element method (BEM) satisfies the last condition, yet one has to deal with singularities in the implementation. We review here how a recently developed singularity-free three-dimensional (3D) boundary element framework with superior accuracy can be used to tackle such problems only using one or a few Helmholtz equations with higher order (quadratic) elements which can tackle complex curved shapes. Examples are given for acoustics (a Helmholtz resonator among others) and electromagnetic scattering.

description: We formally map the problem of sampling from an unknown distribution with a density in $\mathbb{R}^d$ to the problem of learning and sampling a smoother density in $\mathbb{R}^{Md}$ obtained by convolution with a fixed factorial kernel: the new density is referred to as M-density and the kernel as multimeasurement noise model (MNM). The M-density in $\mathbb{R}^{Md}$ is smoother than the original density in $\mathbb{R}^d$, easier to learn and sample from, yet for large $M$ the two problems are mathematically equivalent since clean data can be estimated exactly given a multimeasurement noisy observation using the Bayes estimator. To formulate the problem, we derive the Bayes estimator for Poisson and Gaussian MNMs in closed form in terms of the unnormalized M-density. This leads to a simple least-squares objective for learning parametric energy and score functions. We present various parametrization schemes of interest including one in which studying Gaussian M-densities directly leads to multidenoising autoencoders--this is the first theoretical connection made between denoising autoencoders and empirical Bayes in the literature. Samples in $\mathbb{R}^d$ are obtained by walk-jump sampling (Saremi & Hyvarinen, 2019) via underdamped Langevin MCMC (walk) to sample from M-density and the multimeasurement Bayes estimation (jump). We study permutation invariant Gaussian M-densities on MNIST, CIFAR-10, and FFHQ-256 datasets, and demonstrate the effectiveness of this framework for realizing fast-mixing stable Markov chains in high dimensions.

description: Infotaxis is a popular search algorithm designed to track a source of odor in a turbulent environment using information provided by odor detections. To exemplify its capabilities, the source-tracking task was framed as a partially observable Markov decision process consisting in finding, as fast as possible, a stationary target hidden in a 2D grid using stochastic partial observations of the target location. Here we provide an extended review of infotaxis, together with a toolkit for devising better strategies. We first characterize the performance of infotaxis in domains from 1D to 4D. Our results show that, while being suboptimal, infotaxis is reliable (the probability of not reaching the source approaches zero), efficient (the mean search time scales as expected for the optimal strategy), and safe (the tail of the distribution of search times decays faster than any power law, though subexponentially). We then present three possible ways of beating infotaxis, all inspired by methods used in artificial intelligence: tree search, heuristic approximation of the value function, and deep reinforcement learning. The latter is able to find, without any prior human knowledge, the (near) optimal strategy. Altogether, our results provide evidence that the margin of improvement of infotaxis toward the optimal strategy gets smaller as the dimensionality increases.
