description: Lehrende in der Informatik werden trotz aller Aufgeschlossenheit ggü. Gender- und Diversity-Themen von der in diesem Fachbereich präsenten männlich konnotierten Fachkultur, unreflektierten Machtverhältnissen, fachspezifischen Verhaltensmustern und vorherrschenden geschlechtsspezifischen Normen- und Wertesystemen beeinflusst. Diese inhärenten gesellschaftlichen Strukturen erschweren eine gleichberechtigte Teilhabe aller Geschlechter am Informatikunterricht. Eine weitere Rolle spielen die in der jeweiligen Fachkultur herrschenden (männlichen) Selbstverständnisse und die im Sinne des „Doing Gender“ hergestellten Geschlechterordnungen. Bath fordert in diesem Kontext eine Auseinandersetzung nicht nur mit Frauen in MINT, sondern v. a. mit Gender Studies in MINT im Sinne der „Gender Science“. Sie schlägt u. a. eine „Reflektion des eigenen Anteils an binären Geschlechterkonstruktionen“ in MINT vor. An dieser Stelle setzen wir mit unserem Workshop an. Mit dem an das Identitätenlotto2 angelehnten Spiel soll unter Berücksichtigung der Vorerfahrungen der Teilnehmenden zunächst ein Perspektivwechsel vollzogen werden. Anhand expl. Fallbeispiele werden wir Perspektiven anderer Identitäten betrachten und uns mit eigenen Vorurteilen, Zuschreibungen und Handlungsmustern konfrontieren und unser Unterrichtsverhalten reflektieren. Dazu werden im Workshop folgende Fragen in Bezug auf die betrachteten Identitäten gestellt: Welches genderspezifische Selbstverständnis herrscht in der Fachkultur der Informatik? Welche Expert*innen repräsentieren auf welcher Grundlage die Fachkultur und welche Ein- und Ausschlüsse sind damit verbunden? Wie werden Hierarchien, Gleichberechtigung und Teilhabe gestaltet? Welche Mitgestaltungsmöglichkeiten haben Lernende? Aus dieser Reflexion sollen anschließend konstruktive Lösungsansätze entwickelt werden, die in einem gendersensitiven Informatikunterricht angewandt werden können.

description: The scalar Yukawa model, in which a complex scalar field interact via a real scalar field, is reduced by using covariant Green functions. It is shown that exact few-particle eigenstates of the truncated QFT Hamiltonian can be obtained in the Feshbach-Villars formulation if an unorthodox "empty" vacuum state is used. Analytic solutions for the two-body case are obtained for massless chion exchange in 3+1 dimensions and for massive chion exchange in 1+1 dimensions. Comparison is made to ladder Bethe-Salpeter, Feynman-Schwinger and quasipotential results for massive chion exchange in 3+1. Equations for the three-body case are also obtained.

description: We present a geometric setting for the differential Galois theory of $G$-invariant connections with parameters. As an application of some classical results on differential algebraic groups and Lie algebra bundles, we see that the Galois group of a connection with parameters with simple structural group $G$ is determined by its isomonodromic deformations. This allows us to compute the Galois groups with parameters of the general Fuchsian special linear system and of Gauss hypergeometric equation.

Fragilities of Liquids Predicted from the Random First Order Transition Theory of Glasses

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)

description: A microscopically motivated theory of glassy dynamics based on an underlying random first order transition is developed to explain the magnitude of free energy barriers for glassy relaxation. A variety of empirical correlations embodied in the concept of liquid "fragility" are shown to be quantitatively explained by such a model. The near universality of a Lindemann ratio characterizing the maximal amplitude of thermal vibrations within an amorphous minimum explains the variation of fragility with a liquid's configurational heat capacity density. Furthermore the numerical prefactor of this correlation is well approximated by the microscopic calculation. The size of heterogeneous reconfiguring regions in a viscous liquid is inferred and the correlation of nonexponentiality of relaxation with fragility is qualitatively explained. Thus the wide variety of kinetic behavior in liquids of quite disparate chemical nature reflects quantitative rather than qualitative differences in their energy landscapes.

description: With multiple crowd gatherings of millions of people every year in events ranging from pilgrimages to protests, concerts to marathons, and festivals to funerals; visual crowd analysis is emerging as a new frontier in computer vision. In particular, counting in highly dense crowds is a challenging problem with far-reaching applicability in crowd safety and management, as well as gauging political significance of protests and demonstrations. In this paper, we propose a novel approach that simultaneously solves the problems of counting, density map estimation and localization of people in a given dense crowd image. Our formulation is based on an important observation that the three problems are inherently related to each other making the loss function for optimizing a deep CNN decomposable. Since localization requires high-quality images and annotations, we introduce UCF-QNRF dataset that overcomes the shortcomings of previous datasets, and contains 1.25 million humans manually marked with dot annotations. Finally, we present evaluation measures and comparison with recent deep CNN networks, including those developed specifically for crowd counting. Our approach significantly outperforms state-of-the-art on the new dataset, which is the most challenging dataset with the largest number of crowd annotations in the most diverse set of scenes.

description: Many universities take measures to reduce the number of students dropping out. To support students’ advisors better becomes crucial. Besides their knowledge that they acquire through experience, which is a very important human factor in that process, advisors usually know very little about how students get along in their studies. In this paper, we present preliminary work to support advisors better when meeting students. The current investigation includes two main parts called “overview” and “typical completing behaviours”. The overview part contains visualizations giving general information about how students manage the degree as well as information contrasting students who complete the degree and students who drop out. Typical completing behaviours are obtained through clustering. In this work, data from 2276 students have been analysed.
Performance of cryogenic microbolometers and calorimeters with on-chip coolers

description: Astronomical observations of cosmic sources in the far-infrared and X-ray bands require extreme sensitivity. The most sensitive detectors are cryogenic bolometers and calorimeters operating typically at about 100 mK. The last stage of cooling (from 300 mK to 100 mK) often poses significant difficulties in space-borne experiments, both in system complexity and reliability. We address the possibility of using refrigeration based on normal metal/insulator/superconductor (NIS) tunnel junctions as the last stage cooler for cryogenic thermal detectors. We compare two possible schemes: the direct cooling of the electron gas of the detector with the aid of NIS tunnel junctions and the indirect cooling method, when the detector lattice is cooled by the refrigerating system, while the electron gas temperature is decreased by electron-phonon interaction. The latter method is found to allow at least an order of magnitude improvement in detector noise equivalent power, when compared to the direct electron cooling.

description: 360-degree videos offer new features to extend video-based learning scenarios. In combination with virtual reality (VR) displays such as full-feature or cardboard displays the use of 360-degree video can further support the feeling of immersion and provide more degrees of freedom to look around. This paper presents preliminary results from an interpretive case study (n=16) evaluating the use of 360-degree videos for video reflection of teacher training sessions in a business education context. In two courses students were offered to record their teaching sessions with a 360-degree video camera in order to reflect on their teaching performance. The process of video reflection consisted of watching the video multiple times and answering specific questions on didactics, content and performance. For this case study participants could explore three viewing experiences, a head-mounted display, a cardboard viewer and a web-based player. Based on their experiences made, they were interviewed focusing on the usefulness for video-based self- reflection. Preliminary results show that 360-degree videos are embraced positively and perceived more useful than regular video for reflection. However, challenges were identified for the scalability and usability of 360-degree video content.

description: In this paper we formulate the theory of tunneling into general Abelian fractional quantum Hall edge states. In contrast to the simple Laughlin states, a number of charge transfer processes must be accounted for. Nonetheless, it is possible to identify a unique value corresponding to dissipationless transport as the asymptotic large-$V$ conductance through a tunneling junction, and find fixed points (CFT boundary conditions) corresponding to this value. The symmetries of a given edge tunneling problem determine the appropriate boundary condition, and the boundary condition determines the strong-coupling operator content and current noise.

description: We study the dynamics of a quantum system $Γ$ with an environment $Ξ$ made of $N$ elementary quantum components. We aim at answering the following questions: can the evolution of $Γ$ be characterized by some general features when $N$ becomes very large, regardless of the specific form of its interaction with each and every component of $Ξ$? In other terms: should we expect all quantum systems with a macroscopic environment to undergo a somehow similar evolution? And if yes, of what type? In order to answer these questions we use well established results from large-$N$ quantum field theories, particularly referring to the conditions ensuring a large-$N$ quantum model to be effectively described by a classical theory. We demonstrate that the fulfillment of these conditions, when properly imported into the framework of the open quantum systems dynamics, guarantees that the evolution of $Γ$ is always of the same type of that expected if $Ξ$ were a measuring apparatus, no matter the details of the actual interaction. On the other hand, such details are found to determine the specific basis w.r.t. which $Γ$ undergoes the decoherence dictated by the dynamical description of the quantum measurement process. This result wears two hats: on the one hand it clarifies the physical origin of the formal statement that, under certain conditions, any channel from $ρ_Γ$ to $ρ_Ξ$ takes the form of a measure-and-prepare map, as recently shown in Ref. [1]; on the other hand, it formalizes the qualitative argument that the reason why we do not observe state superpositions is the continual measurement performed by the environment.

Cavity optomechanics offers the ideal system to achieve this by combing high precision optical measurements with mechanical oscillators. However, mechanical quantumness can only be established if the behaviour is incompatible with any classical description of an oscillator. After explicitly considering classical and hybrid quantum-classical descriptions of an optomechanical system, we rule out squeezing of the optical field as such a witness by showing it is also predicted without quantizing the mechanical oscillator.

description: We show NP-hardness of a generalized quadratic programming problem, which we called Unconstrained N-ary Quadratic Programming (UNQP). This problem has recently become practically relevant in the context of novel memristor-based neuromorphic microchip designs, where solving the UNQP is a key operation for on-chip training of the neural network implemented on the chip. UNQP is the problem of finding a vector $\mathbf{v} \in S^N$ which minimizes $\mathbf{v}^T\,Q\,\mathbf{v} +\mathbf{v}^T \mathbf{c} $, where $S = \{s_1, \ldots, s_n\} \subset \mathbb{Z}$ is a given set of eligible parameters for $\mathbf{v}$, $Q \in \mathbb{Z}^{N \times N}$ is positive semi-definite, and $\mathbf{c} \in \mathbb{Z}^{N}$. In memristor-based neuromorphic hardware, $S$ is physically given by a finite (and small) number of possible memristor states. The proof of NP-hardness is by reduction from the Unconstrained Binary Quadratic Programming problem, which is a special case of UNQP where $S = \{0, 1\}$ and which is known to be NP-hard.

description: After introducing essential, qualitative concepts and results, we discuss the application of Dyson-Schwinger equations to QCD at finite T and mu. We summarise the calculation of the critical exponents of two-light-flavour QCD using the chiral and thermal susceptibilities; and an algebraic model that elucidates the origin of an anticorrelation between the mu- and T-dependence of a range of meson properties. That model also provides an algebraic understanding of why the finite-T behaviour of bulk thermodynamic properties is mirrored in their mu-dependence, and why meson masses decrease with mu even though f_pi and - increase. The possibility of diquark condensation is canvassed. Its realisation is uncertain because it is contingent upon an assumption about the quark-quark scattering kernel that is demonstrably false in some applications; e.g., it predicts the existence of coloured diquarks in the strong interaction spectrum, which are not observed.

description: We analyse the orbital kinematics of the Milky Way (MW) satellite system utilizing the latest systemic proper motions for 38 satellites based on data from Gaia Data Release 2. Combining these data with distance and line-of-sight velocity measurements from the literature, we use a likelihood method to model the velocity anisotropy, $β$, as a function of Galactocentric distance and compare the MW satellite system with those of simulated MW-mass haloes from the APOSTLE and Auriga simulation suites. The anisotropy profile for the MW satellite system increases from $β\sim -2$ at $r\sim20$ kpc to $β\sim 0.5$ at $r\sim200$ kpc, indicating that satellites closer to the Galactic centre have tangentially-biased motions while those farther out have radially-biased motions. The motions of satellites around APOSTLE host galaxies are nearly isotropic at all radii, while the $β(r)$ profiles for satellite systems in the Auriga suite, whose host galaxies are substantially more massive in baryons than those in APOSTLE, are more consistent with that of the MW satellite system. This shape of the $β(r)$ profile may be attributed to the central stellar disc preferentially destroying satellites on radial orbits, or intrinsic processes from the formation of the Milky Way system.

description: Alle Lehrpersonen benötigen – unabhängig von ihren konkreten Fächern – angesichts einer von Informatik durchdrungenen Welt einen Zugang zu allgemeinbildenden Elementen der Informatik. An der Bergischen Universität Wuppertal werden seit 2009 regelmäßig Veranstaltungen durchgeführt, die dieser Anforderung Rechnung tragen. Befragungen und Rückmeldungen der Studierenden sowie der Lehrenden aus der mehrjährigen Durchführung der Veranstaltung legten nahe, dass eine für alle Lehramtsstudierenden adäquate Optimierung der Veranstaltung möglich ist. Daraus ergibt sich als eine zu untersuchende Hypothese: Das bestehende Lehrangebot muss – hinsichtlich der intendierten Kompetenzen für die Studierenden – als nicht vollständig befriedigend bezeichnet werden. Durch die Rekonfiguration der Veranstaltung werden Möglichkeiten zur Qualitätsverbesserung des Lehrangebots diskutiert. Die Umgesetzung wird prozessbegleitend untersucht, um gegebenenfalls zeitnah zu intervenieren. Durch qualitative Forschungselemente konnten studentische Belange inhaltlicher und organisatorischer Art auf die Hypothese bezogen werden und diese in erster Näherung bestätigen. Die Hinzunahme zweier informatikfachwissenschaftlicher und fachdidaktischer Perspektiven gewährleistet die Triangulation des konzeptuellen Reformprozesses. Das entwickelte Konzept einer allgemeinbildenden Informatikveranstaltung für alle Lehramtsstudierenden berücksichtigt eine verstärkte Verzahnung von Theorie und Praxis, inhaltliche Modularität und konkreten Berufs- bzw. Lebensweltbezug.

description: We observed room-temperature intersubband transitions at 1.26 microns in n-doped type-II In$_{0.3}$Ga$_{0.7}$As/AlAs strained quantum wells. An improved tight-binding model was used to optimize the structure parameters in order to obtain the shortest wavelength intersubband transition ever achieved in a semiconductor system. The corresponding transitions occur between the first confined electronic levels of the well following mid-infrared optical pumping of electrons from the barrier X-valley into the well ground state.

description: The density matrix of a non-relativistic quantum system, divided into $N$ sub-systems, is rewritten in terms of the set of all partitioned density matrices for the system. For the case where the different sub-systems are distinguishable, we derive a hierarchy of equations of motion linking the dynamics of all the partitioned density matrices, analogous to the "Schwinger-Dyson" hierarchy in quantum field theory. The special case of a set of $N$ coupled spin-$1/2$ "qubits" is worked out in detail. The equations are then rewritten in terms of a set of "entanglement correlators", which comprise all the possible correlation functions for the system - this case is worked out for coupled spin systems. The equations of motion for these correlators can be written in terms of a first-order differential equation for an entanglement correlator supervector.

description: On-line chemical characterization of real-world particle emissions from 13 transit buses was performed using a chemical ionization mass spectrometer (CIMS) equipped with a filter inlet for gases and aerosols (FIGAERO). In addition to the fresh emissions the emissions were artificially aged using a potential aerosol mass reactor (Go:PAM). The buses studied were running on different fuel types (diesel, compressed natural gas, and rapeseed methyl ester) and exhaust after-treatment systems (selective catalytic reduction (SCR), exhaust gas recirculation (EGR), and a three-way catalyst). When evaluating emissions from passing exhaust plumes using the FIGAERO ToF-CIMS, two technical features were highlighted from this work, the use of high mass calibrants and the factor enhancement method to be able to filter important compounds from mass spectra including hundreds of species. Here, acetate was used as the reagent ion to enable detection of highly oxygenated species in the exhaust particle emissions with potential high toxicity and/or secondary organic aerosol formation (SOA) potential. The acetate ionization scheme accounted for 4% to 46% of the total emitted particulate mass through identification of 61 species in the spectra. For aged emission the various fuel types provided overlapping species that could explain up to 19% of the aged emissions. This is hypothesized to come from the oxidation of engine lubrication oil, thus a common source for various fuels which was further supported by laboratory measurements. Specific markers from the SCR technology, such as urea oxidation products and further byproducts from hydrolysis were identified and attributed to reactions of isocyanic acid.

description: We use the Fermi-LAT gamma-ray observatory to search for gamma-ray emission from four nearby, debris disk-hosting main sequence stars: $τ$ Ceti, $ε$ Eridani, Fomalhaut, and Vega. For three stars ($τ$ Ceti, Fomalhaut, and Vega), we establish upper limits that are consistent with theoretical expectations. For $ε$ Eridani, we find a possible spatially coincident source with a soft energy spectrum of $dN/dE \sim E^{-3.6}$. However, at this stage we are unable to rule out that this emission is due to a more extended feature in the diffuse background. In the interpretation that the emission is due to $ε$ Eridani, the $> 100$ MeV gamma-ray luminosity is $\sim 10^{27}$ erg/s $\simeq 3\times 10^{-7}$ L$_\odot$, which is $\sim 10^{10}$ times the gamma-ray luminosity from the disk of the quiet Sun. We find $\lesssim 2 σ$ evidence of source variability over a $\sim 7$ year timescale. In the interpretation that the gamma-ray emission from $ε$ Eridani itself, we consider two possible models: 1) cosmic-ray collisions with solid bodies in the debris disk which extends out $\sim$60 AU from the host star, and 2) emission from the stellar activity. For the former model, assuming a total disk mass consistent with infrared measurements, we find that the size distribution of bodies is steeper than expected for a collisional cascade state. If confirmed as being associated with $ε$ Eridani, this would be the first indication of gamma-ray emission from the vicinity of a main sequence star other than the Sun.

description: We use a phase space description to (re)derive a first order form of the Born-Infeld action for D-branes. This derivation also makes it possible to consider the limit where the tension of the D-brane goes to zero. We find that in this limit, which can be considered to be the strong coupling limit of the fundamental string theory, the world-volume of the D-brane generically splits into a collection of tensile strings.
