description: Data driven approaches for decision making applied to automated driving require appropriate generalization strategies, to ensure applicability to the world's variability. Current approaches either do not generalize well beyond the training data or are not capable to consider a variable number of traffic participants. Therefore we propose an invariant environment representation from the perspective of the ego vehicle. The representation encodes all necessary information for safe decision making. To assess the generalization capabilities of the novel environment representation, we train our agents on a small subset of scenarios and evaluate on the entire diverse set of scenarios. Here we show that the agents are capable to generalize successfully to unseen scenarios, due to the abstraction. In addition we present a simple occlusion model that enables our agents to navigate intersections with occlusions without a significant change in performance.

description: Mini-Mental State Examination (MMSE) is used as a diagnostic test for dementia to screen a patient’s cognitive assessment and disease severity. However, these examinations are often inaccurate and unreliable either due to human error or due to patients’ physical disability to correctly interpret the questions as well as motor deficit. Erroneous data may lead to a wrong assessment of a specific patient. Therefore, other clinical factors (e.g., gender and comorbidities) existing in electronic health records, can also play a significant role, while reporting her examination results. This work considers various clinical attributes of dementia patients to accurately determine their cognitive status in terms of the Mini-Mental State Examination (MMSE) Score. We employ machine learning models to calibrate MMSE score and classify the correctness of diagnosis among patients, in order to assist clinicians in a better understanding of the progression of cognitive impairment and subsequent treatment. For this purpose, we utilize a curated real-world ageing study data. A random forest prediction model is employed to estimate the Mini-Mental State Examination score, related to the diagnostic classification of patients.This model uses various clinical attributes to provide accurate MMSE predictions, succeeding in correcting an important percentage of cases that contain previously identified miscalculated scores in our dataset. Furthermore, we provide an effective classification mechanism for automatically identifying patient episodes with inaccurate MMSE values with high confidence. These tools can be combined to assist clinicians in automatically finding episodes within patient medical records where the MMSE score is probably miscalculated and estimating what the correct value should be. This provides valuable support in the decision making process for diagnosing potential dementia patients. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

description: The effects of partial substitution of dysprosium in Tb0.2Dy0.8Co2 by terbium and gadolinium on the structure and magnetic properties have been studied. Two compositions, Tb0.3Dy0.7Co2 and Tb0.2Dy0.7Gd0.1Co2 have been synthesized. Their crystal structure, in contrast to the structure of the original compound, has both tetragonal distortions and rhombohedral distortions at lower temperatures. Anomalies of magnetostriction and magnetocaloric effect near the observed magnetic phase transitions have been studied. The sign-alternating temperature dependences of the longitudinal and transverse magnetostrictions associated with various types of crystal structure distortions of the alloys are revealed.

description: The green alga {\it Chlamydomonas} swims with synchronized beating of its two flagella, and is experimentally observed to exhibit run-and-tumble behaviour similar to bacteria. Recently we studied a simple hydrodynamic three-sphere model of {\it Chlamydomonas} with a phase dependent driving force which can produce run-and-tumble behaviour when intrinsic noise is added, due to the non-linear mechanics of the system. Here, we consider the noiseless case and explore numerically the parameter space in the driving force profiles, which determine whether or not the synchronized state evolves from a given initial condition, as well as the stability of the synchronized state. We find that phase dependent forcing, or a beat pattern, is necessary for stable synchronization in the geometry we work with.

description: We prepared a powder sample of edwardsite Cd2Cu3(SO4)2(OH)6 4H2O, which is a new candidate compound for the spin-1/2 kagome antiferromagnet, and studied its magnetic properties by magnetic susceptibility and heat capacity measurements. Edwardsite has a deformed kagome lattice with an average antiferromagnetic interaction of 51 K between nearby spins and shows an antiferromagnetic order accompanied by a small ferromagnetic moment below 4.3 K. The weak ferromagnetism is likely due to spin canting caused by sizable Dzyaloshinsky-Moriya interactions, which may stabilize the long-range magnetic order instead of a spin-liquid state expected for the kagome antiferromagnet.

description: It is well-known that a quantum of light (photon) has a zero mass in vacuum. Entering into a medium the photon creates a quasiparticle (polariton, plasmon, surface-phonon, surface-plasmon polariton, etc.) whose rest mass is generally not zero. In this letter, devoted to the memory of Mark Stockman, we evaluate the rest mass of light-induced surface-plasmon polaritons (SPPs) and discuss an idea that collisions of two massive SPP quasiparticles can result in changes of their frequencies according to the energy and momentum conservation laws. © 2021 Nikolai B.

description: We study the time evolution of an incompressible fluid with axial symmetry without swirl, assuming initial data such that the initial vorticity is very concentrated inside $N$ small disjoint rings of thickness $\varepsilon$ and vorticity mass of the order of $|\log\varepsilon|^{ -1}$. When $\varepsilon \to 0$ we show that the motion of each vortex ring converges to a simple translation with constant speed (depending on the single ring) along the symmetry axis. We obtain a sharp localization of the vorticity support at time $t$ in the radial direction, whereas we state only a concentration property in the axial direction. This is obtained for arbitrary (but fixed) intervals of time. This study is the completion of a previous paper arXiv:1904.04785 [math-ph], where a sharp localization of the vorticity support was obtained both along the radial and axial directions, but the convergence for $\varepsilon\to 0$ worked only for short times.

EKT Platform

description: EKT project developed an advanced e-learning system for in-school teaching practice (in-school placement) by integrating, adapting and improving different existent open source tools (some of them provided by technological partners), as well as designing some new features to provide support for communication, reflection and follow-up for students, teachers and mentors.
 Today there are a number of e-learning tools that provide several generic educational services such as communication, documents repository, e-Portfolios, agendas, etc. but there are not specific platforms that support the process of future teachers in-school placement, taking into account a tailored response to the needs of all the participant agents in the process.
 The complexity of this task meant the identification of the most appropriate features and tools and their adaptation to create a unified platform, providing a seamless connection and exchange of information between tools to provide an informative dashboard for teachers and students, meeting the methodological requirements and the needs for improvement detected
 in teaching practices. The challenge was also to make interoperable technological tools provided by both private companies and opensource developments and articulate them around a versatile system of tools and digital resources for training in student teacher’s practice. This report describes the process of developing the EKT e-learning platform and its architecture and functionalities. It also includes demo access so that it can be tested and links to download the source code of the EKT platform. it is therefore a report describing a collective creation.

 The EKT technological platform is the result of an interdisciplinary work carried out by the technological partners of the consortium on the basis of the needs analysis carried out in (WP2) and the educational and technological framework defined in (WP3: Educational and technological framework for development of professional competences in in-school placement (Final version). Its development has been defined by a Design-Based Research process piloted by USC and CESGA with two iterations in two academic years and in 5 European Initial Teacher Education institutions.

 This EKT platform, together with the EKT educational and technological framework finally integrate the EKT elearning system for internships and constitute an innovative proposal for initial teacher training.

description: The cross sections of the $^{130}$Sn(n,$γ$)$^{131}$Sn and $^{132}$Sn(n,$γ$)$^{133}$Sn reactions are calculated in the direct capture model at low energies below 1.5\,MeV. Using recent data from (d,p) transfer experiments on $^{130}$Sn and $^{132}$Sn, it is possible to avoid global input parameters with their inherent uncertainties and to determine all input to the direct capture model by local adjustments. The calculated direct capture cross sections of $^{130}$Sn and $^{132}$Sn are almost identical and have uncertainties of less than a factor of two. The stellar reaction rates $N_A < σv >$ show a slight increase with temperature. Finally an estimate for the influence of low-lying resonances to the stellar reaction rates is given.

description: In this article, we report the results of comparative studies of photoelectrochemical behavior of the binary CdS/TiO2 and WO3/TiO2 and ternary CdS/WO3/TiO2 heterostructures based on titania nanotube and planar structures. Physical–chemical characterization by XRD, XPS, and electron microscopy methods together with electrochemical impedance spectroscopy measurements confirm a successful formation of heterostructured electrodes, both nanotube-based and planar. The results of photoelectrochemical studies of the heterostructures demonstrate a significant difference in their behavior depending on the structure geometry and the character of the formed heterojunctions. It is concluded that nanotube-based heterostructure electrodes can be characterized by a stochastic set of different heterojunctions while planar systems demonstrate well-ordered heterojunctions with a strictly defined electron transfer direction. Particularly, we demonstrate the possibility of the realization of Z-scheme of photoexcitation and charge separation in ternary planar systems under visible light irradiation.

description: Data literacy has been defined as “the ability to read, work with, analyze and argue with data”. The United Nations has highlighted a growing risk of inequality for people excluded from the new world of data by lack of education, language, poverty, and discrimination and has called for the development of data literacy at all levels of society. Responses to data are shaped by personal, social and cultural influences, as well as by trust in the source. The arts can play an important role in regulating our responses to information and increasing accessibility, engagement and sense-making of data. However, to our knowledge, to date, there has been no comprehensive review of publications on the role of the arts in the context of data literacy. This paper presents a protocol and a methodological framework to perform a scoping review to identify and map the available evidence for the role of the arts in enhancing data literacy. The review aims to provide an overview of research over the past twenty years to develop a clearer understanding of (a) which art forms are represented in the literature (b) which population groups and settings are identified (c) and the rationale for using the arts to enhance data literacy.

description: Several critical issues, such as the shuttling effect and the sluggish reaction kinetics, exist in the design of high-performance lithium–sulfur (Li-S) batteries. Here, it is reported that nitrogen doping can simultaneously and significantly improve both the immobilization and catalyzation effects of Co9S8 nanoparticles in Li-S batteries. Combining the theoretical calculations with experimental investigations, it is revealed that nitrogen atoms can increase the binding energies between LiPSs and Co9S8, and as well as alleviate the sluggish kinetics of Li-S chemistry in the Li2S6 cathode. The same effects are also observed when adding N-Co9S8 nanoparticles into the commercial Li2S cathode (which has various intrinsic advantages, but unfortunately a high overpotential). A remarkable improvement in the battery performances in both cases is observed. The work brings heteroatom-doped Co9S8 to the attention of designing high-performance Li-S batteries. A fundamental understanding of the inhibition of LiPSs shuttle and the catalytic effect of Li2S in the newly developed system may encourage more effort along this interesting direction. © 2020 The Authors.

description: Seit der Markteinführung der zielverfolgenden Tachymeter Anfang der 90iger Jahre und der etwa gleichzeitigen Verfügbarkeit von GPS- bzw. GNSS-Empfängern haben sich die geodätischen und geotechnischen Monitoringanwendungen stetig weiterentwickelt. Neben den kommerziellen Systemen der bekannten Hersteller existieren verschiedene Soft- und Hardwarelösungen einzelner Büros, Organisationen und Hochschulen. Heutzutage werden verstärkt geodätische und geotechnische Low-cost-Sensoren und -Komponenten für permanente Überwachungsaufgaben verwendet. In Kombination mit kleinen Micro-Controllern und Micro-Prozessoren (z.B. dem Raspberry Pi oder die verschiedenen Typen der Arduino-Boards) ergeben sich individuelle Möglichkeiten in der Ingenieurvermessung und Geotechnik. Modular vernetzte Sensoren in unterschiedlichen Netzwerken, meist als Geosensornetzwerke bezeichnet (Heunecke et al., 2013), arbeiten dabei mit geringen Ressourcen optimal abgestimmt zusammen. Dabei kann eine große Anzahl von Subsystemen in einem zentralen Mess-, Steuer- und Auswertesystem für individuellen Anforderungen zusammengestellt werden. Dieser Beitrag stellt einen holistischen Ansatz für flexible und kostengünstige Anwendungen zur automatisierten Überwachung von technischen Anlagen und Bauwerken nach Vorgaben des Bauingenieurwesens sowie die Durchführung von Überwachungsprojekten in den verschiedenen Bereichen der Geowissenschaften dar. Zusätzlich werden verschiedene Implementierungen mit einzelnen Sensoren mit individueller Konfiguration des gesamten Geosensornetzwerkes erläutert. Der Schwerpunkt des Beitrags liegt neben den geodätischen Komponenten wie Tachymetrie, Low-Cost-GNSS, Neigungssensoren und Nivellement in der Verwendung der geotechnischen Sensoren und deren Echtzeitverarbeitung mit dem Raspberry Pi und dem Arduino Uno.

description: Zusammenfassung

1.  Seit Mitte der 1990er Jahre steigen die Löhne in Deutschland deutlich langsamer als in anderen europäischen Ländern. Die Verbesserung der preislichen Wettbewerbsfähigkeit der deutschen Industrie in Verbindung mit hoher Innovationsdynamik hat die deutschen Exporte explodieren lassen.
2.  Gleichzeitig stagnierte die Binnennachfrage – bei den niedrigen Einkommensgruppen waren Rückgänge der Reallöhne, zum Teil sogar der Nominallöhne zu verzeichnen.
3. Deutschland hat mit seinen Exportüberschüssen und der Vernachlässigung seiner Binnennachfrage zu den Ungleichgewichten in Europa beigetragen. Mit seiner Politik der Lohnzurückhaltung zwingt es andere Länder in einen Lohnsenkungswettbewerb, der allgemein sinkende Wachstumsraten und anhaltende Stagnation befürchten lässt.
4. Deutschland muss mehr für seine Binnennachfrage tun. Mehr Kaufkraft für die Beschäftigten stärkt nicht nur gut den sozialen Zusammenhalt, damit werden auch die Importe angekurbelt und die anderen Euro-Länder bei ihren Konsolidierungsbemühungen entlastet.
5. Ein Politikwechsel von der Lohnzurückhaltung zu einer langfristigen, wieder am Verteilungsspielraum orientierten Lohnpolitik kann ohne staatliche Unterstützung und neue Instrumente der Lohnpolitik nicht gelingen.
6. Das deutsche Tarifsystem braucht mindestens drei neue Gehhilfen, um wieder auf die Beine zu kommen: einen allgemeinen Mindestlohn – wie in den meisten Nachbarländern längst eingeführt; die Vereinfachung der Allgemeinverbindlichkeitserklärung von Tarifverträgen; neue Regelungen für Leiharbeit und Minijobs, um den Missbrauch dieser „Instrumente“ zur Absenkung des Lohnniveaus in den Betrieben zu verhindern.

These possibilities imply differences not only in the spectral energy distribution (SED) but also in the variability signatures, especially in the X- and $γ$-ray regime. Thus, the temporal behavior of each leptohadronic scenario can be used to probe the particle population responsible for the high-energy emission as it can give extra information not available by spectral fits. In the present work we apply these ideas to the non-thermal emission of Mrk 421. We focus on the observations of March 2001, since during that period Mrk 421 showed multiple flares that have been observed in detail both in X-rays and $γ$-rays. First, we obtain pre-flaring fits to the SED using the different types of leptohadronic scenarios. Then, we introduce random-walk type, small-amplitude variations on the injection compactness or on the maximum energy of radiating particles and follow the subsequent response of the radiated photon spectrum. For each leptohadronic scenario, we calculate the X-ray and $γ$-ray fluxes and investigate their possible correlation. Whenever the `input' variations lead, apart from flux variability, also to spectral variability, we present the resulting relations between the spectral index and the flux, both in X-rays and $γ$-rays. We find that proton synchrotron models are favoured energetically but require fine tuning between electron and proton parameters to reproduce the observed quadratic behaviour between X-rays and TeV $γ-$rays. On the other hand, models based on pion-decay can reproduce this behaviour in a much more natural way.

description: This dissertation brings together four articles that have been written over a several years and use a range of quantitative data and methods to explore questions about the determinants and effects of social exclusion. An overarching conceptual framework is also formulated in an outline paper. The individual articles are placed in this framework and the contents are reflected upon. For this purpose, the current state of research is consulted in each case in order to obtain an updated assessment of the relevance of the research question and the methods used. The individual contributions draw on different theoretical considerations, which predominantly refer to stress-theoretical approaches, which in turn are to be made fruitful for the analysis of feelings of belonging or exclusion and their consequences for psychological well-being. The work can therefore contribute to analytical-empirical research on exclusion.

description: Die Entwicklung der Vegetationsstruktur und des Blütenangebots von Blühstreifen ist im jahreszeitlichen Verlauf bisher wenig erforscht. Dieses Wissen ist aber entscheidend, auch um faunistische Untersuchungsergebnisse interpretieren zu können. Eines der Ziele des Forschungsvorhabens „Nutzungsorientierte Ausgleichsmaßnahmen bei der Biogasproduktion“ war es daher, charakteristische Merkmale verschiedener Blühstreifentypen herauszuarbeiten, um dann in Verbindung mit floristischen und faunistischen Untersuchungen Empfehlungen zur Anlage von Blühstreifen abzuleiten. Dazu wurden auf sechs unterschiedlichen Blühstreifentypen Vegetationsstruktur und floristische Merkmale über verschiedene Jahreszeiten zwischen 2012 und 2014 erfasst. Als Referenzflächen wurden zudem vier Saumtypen untersucht. Vor allem im ersten Standjahr weisen Blühstreifen ein wesentlich höheres Blütenangebot als die Säume auf. Ferner kann durch die Anlage von Blühstreifen die Strukturvielfalt erhöht werden, insbesondere wenn sie einen gewissen Offenbodenanteil aufweisen. Die Vegetation auf Blühstreifen unterschiedlicher Standzeiten entwickelt sich zeitlich versetzt, und die verschiedenen Altersstadien ergänzen sich im jahreszeitlichen Verlauf. Das gute Auflaufen der Blühmischung im 1. Standjahr ist auch für die Ausprägung im Folgejahr wichtig. In einem Landschaftsausschnitt sollte deshalb ein Mosaik unterschiedlich alter Blühstreifen geschaffen werden, so dass ein optimales Verhältnis der verschiedenen Strukturen und Blütenangebote über das gesamte Jahr vorhanden ist.

description: Software systems are becoming increasingly complex. Their ubiquitous presence makes users more dependent on their correctness in many aspects of daily life. As a result, there is a growing need to make software systems and their decisions more comprehensible, with more transparency in software-based decision making. Transparency is therefore becoming increasingly important as a non-functional requirement. However, the abstract quality aspect of transparency needs to be better understood and related to mechanisms that can foster it. The integration of explanations into software has often been discussed as a solution to mitigate system opacity. Yet, an important first step is to understand user requirements in terms of explainable software behavior: Are users really interested in software transparency and are explanations considered an appropriate way to achieve it? We conducted a survey with 107 end users to assess their opinion on the current level of transparency in software systems and what they consider to be the main advantages and disadvantages of embedded explanations. We assess the relationship between explanations and transparency and analyze its potential impact on software quality. As explainability has become an important issue, researchers and professionals have been discussing how to deal with it in practice. While there are differences of opinion on the need for built-in explanations, understanding this concept and its impact on software is a key step for requirements engineering. Based on our research results and on the study of existing literature, we offer recommendations for the elicitation and analysis of explainability and discuss strategies for the practice. © 2020, The Author(s).

description: A distant-neighbor quantum-mechanical method is used to study the nonlinear optical wave mixing in graphene nanoflakes (GNFs), including sum- and difference-frequency generation, as well as four-wave mixing. Our analysis shows that molecular-scale GNFs support quantum plasmons in the visible spectrum region, and significant enhancement of nonlinear optical wave mixing is achieved. Specifically, the second- and third-order wave-mixing polarizabilities of GNFs are dramatically enhanced, provided that one (or more) of the input or output frequencies coincide with a quantum plasmon resonance. Moreover, by embedding a cavity into hexagonal GNFs, we show that one can break the structural inversion symmetry and enable otherwise forbidden second-order wave mixing, which is found to be enhanced by the quantum plasmon resonance too. This study reveals that the molecular-sized graphene could be used in the quantum regime for nanoscale nonlinear optical devices and ultrasensitive molecular sensors.

description: Die Ableitung und Modellierung von vertikalen Landbewegungen an der deutschen Nord- und Ostseeküste hat u.a. das Ziel, den Einfluss der Landsenkung bzw. –hebung an der Küste von scheinbaren Pegelanstiegen trennen zu können. Für die Berechnung eines großräumigen landseitigen Bewegungsmodells ist es zunächst erforderlich die Höhenänderungen über längere Zeiträume aus GNSS- und Radarinterferometrie-Beobachtungen zu bestimmen. Im Rahmen dieses Beitrages werden die Berechnungsschritte und erste vorläufige Ergebnisse für die Höhenänderungen an den GNSS-Stationen für den Zeitraum von 2010 bis 2016, sowie Zeitreihen aus der PS-Interferometrie der Sentinel-1 Satelliten für die Jahre 2014 bis 2018 vorgestellt.

description: A recent global fit to the CMSSM incorporating current constraints on supersymmetry, including missing transverse energy searches at the LHC, BR(B_s to mu+ mu-) and the direct XENON100 search for dark matter, favours points towards the end of the stau-neutralino (stau_1- chi) coannihilation strip with relatively large m_1/2 and 10 < tan beta < 40 and points in the H/A rapid-annihilation funnel with tan beta ~ 50. The coannihilation points typically have m_stau_1-m_chi < 5 GeV, and a significant fraction, including the most-favoured point, has m_stau_1-m_chi < m_tau. In such a case, the stau_1 lifetime would be so long that the stau_1 would be detectable as a long-lived massive charged particle that may decay inside or outside the apparatus. We show that CMSSM scenarios close to the tip of the coannihilation strip for tan beta < 40 are already excluded by LHC searches for massive charged particles, and discuss the prospects for their detection in the CMS and ATLAS detectors via time-of-flight measurements, anomalous heavy ionization or decays into one or more soft charged particles.

description: Gout is an inherited and common inflammatory arthritic disease. Many researchers will identify polymorphic loci of gout susceptibility by conducting genome-wide association studies (GWAS). In the present study, the enrichment analysis and chromosomal distribution were performed using predicted polymorphic loci associated with gout risk. The polymorphic loci associated to gout were obtained from the GWAS database. Overall, this database contains 64,806 gout patients and 2,856,174 controls. Gene ontology functional annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed by using the Enrichr online server. A total of 110 common polymorphic protein-coding loci associated with gout risk were identified and included in the analysis. The results of the KEGG analysis showed that the gout-associated loci were mainly related to ABC transporters, endocrine and other factor-regulated calcium reabsorption, and gastric acid secretion pathways. The gene ontology analysis showed that the biological processes of the gout-associated loci were vascular transport, transport across the blood-brain barrier, positive regulation of transporter activity, and positive regulation of transcription by RNA polymerase II. The top cellular component was the external side of the apical plasma membrane. Statistical analysis revealed that the human chromosome segments 1q22, 4p16.1, 6p21.1-p21.2, 11q13.1-q13.2, 12q13.11-q13.3, and 12q24.1 had significantly bearing higher numbers of gout susceptibility loci.

description: A Newtonian model of non-conductive, charged, perfect fluid tori orbiting in combined spherical gravitational and dipolar magnetic fields is presented and stationary, axisymmetric toroidal structures are analyzed. Matter in such tori exhibits a purely circulatory motion and the resulting convection carries charges into permanent rotation around the symmetry axis. As a main result, we demonstrate the possible existence of off-equatorial charged tori and equatorial tori with cusps enabling outflows of matter from the torus also in the Newtonian regime. These phenomena represent qualitatively a new consequence of the interplay between gravity and electromagnetism. From an astrophysical point of view, our investigation can provide insight into processes that determine the vertical structure of dusty tori surrounding accretion disks.
