subject: Schule

description: Virtual Reality (VR) wird zunehmend als vielversprechendes Instrument zur Förderung der Inklusion in der Schulbildung betrachtet [Sc23, Pa17]. Das Didaktische Modell für Inklusives Lehren und Lernen (DiMiLL) [Fr19] wird als theoretischer Rahmen genutzt, um die Wirksamkeit von VR bei der Förderung von Partizipation, Kommunikation, Reflexion und Kooperation in exemplarischen Anwendungen aus der Literatur zu untersuchen. Die Analyse der Literatur zeigt, dass VR ein großes Potenzial hat, inklusive Bildung zu unterstützen, aber auch Herausforderungen hinsichtlich der technischen Umsetzung und der notwendigen Kompetenzen von Lehrkräften und Lernenden mit sich bringt. Ausgehend von den identifizierten Inklusionsaspekten und der Fragestellung nach Umsatzbarkeitskonzepten diskutiert der Beitrag die Notwendigkeit, systematisch grundlegende Gestaltungsprinzipien für inklusionsorientierte VR-Anwendungen im schulischen Kontext zu entwickeln.

description: In this paper, we discuss the impact of neutrino phenomenology and related cosmology on an $A_{4}\otimes Z_{8}$ symmetric $ν$2HDM along with an addition of a new particle, i.e. a gauge singlet(S). The additional particle is a sterile neutrino which is considered to be a probable dark matter candidate in our work. With the choice of sterile neutrino mass in keV range we evaluate the active-DM mixing angle, decay rate and relic abundance considering various cosmological constraints. Simultaneously, a detailed analysis on baryogenesis and neutrinoless double beta decay is also carried out for low scale right-handed neutrino masses. We have considered various bounds from experiments such as Lyman-$α$, X-ray observation, Planck data and KamLAND-Zen limit to validate the model w.r.t the phenomena studied in it.

description: We report resistivity and upper critical field B_c2(T) data for disordered (As deficient) LaO_0.9F_0.1FeAs_1-delta in a wide temperature and high field range up to 60 T. These samples exhibit a slightly enhanced superconducting transition at T_c = 28.5 K and a significantly enlarged slope dB_c2/dT = -5.4 T/K near T_c which contrasts with a flattening of B_c2(T) starting near 23 K above 30 T. The latter evidences Pauli limiting behaviour (PLB) with B_c2(0) approximately 63 T. We compare our results with B_c2(T)-data from the literature for clean and disordered samples. Whereas clean samples show almost no PLB for fields below 60 to 70 T, the hitherto unexplained pronounced flattening of B_c2(T) for applied fields H II ab observed for several disordered closely related systems is interpreted also as a manifestation of PLB. Consequences are discussed in terms of disorder effects within the frames of (un)conventional superconductivity, respectively.

description: Many energetic gamma-ray pulsars discovered by Fermi are promising candidates
for optical follow-ups. We present the results of the first deep optical
observations of the two Vela-like Fermi pulsars PSR J1357-6429 and PSR
J1048-5832 performed with the VLT. However, they have not been detected down to
V~27 and V~27.6, respectively (3 sigma). These upper limits suggest an
efficiency in converting spin-down power into optical luminosity < 7x10d-7 and
<6x10d-6, respectively, lower than the Crab pulsar and, possibly, more
compatible with the spin-down age of these two pulsars.

description: The T980 crystal collimation experiment is underway at the Tevatron to
determine if this technique could increase 980 GeV beam-halo collimation
efficiency at high-energy hadron colliders such as the Tevatron and the LHC.
T980 also studies various crystal types and parameters. The setup has been
substantially enhanced during the Summer 2009 shutdown by installing a new
O-shaped crystal in the horizontal goniometer, as well as adding a vertical
goniometer with two alternating crystals (O-shaped and multi-strip) and
additional beam diagnostics. First measurements with the new system are quite
encouraging, with channeled and volume-reflected beams observed on the
secondary collimators as predicted. Investigation of crystal collimation
efficiencies with crystals in volume reflection and channeling modes are
described in comparison with an amorphous primary collimator. Results on the
system performance are presented for the end-of-store studies and for entire
collider stores. The first investigation of colliding beam collimation
simultaneously using crystals in both the vertical and horizontal plane has
been made in the regime with horizontally channeled and vertically
volume-reflected beams. Planning is underway for significant hardware
improvements during the FY10 summer shutdown and for dedicated studies during
the final year of Tevatron operation and also for a "post-collider beam physics
running" period.
Carbon monoxide reduction of aqueous silver acetate
Creators: name: McAndrew, Robert Thomson
Publisher: name: University of British Columbia
Year: 2011

description: The kinetics of the carbon monoxide reduction of silver perchlorate in sodium acetate - acetic acid buffered aqueous solution were studied between 60 and 110°C by following the pressure decrease in a closed system. The reduction occurs homogeneously in the liquid phase by two parallel reaction paths, one of which is independent of pH. The second path is favoured by increased pH and has both an acetate-independent and an acetate-dependent component. The observed kinetics are consistent with the formation of intermediate complexes by the insertion of a carbon monoxide molecule between a silver ion and a co-ordinated oxygen-donating base (e.g. OAc[superscript -], H₂O) according to the following mechanism: [Chemical formulae omitted] Silver-acetate complexes are about a factor of three more reactive than hydrated silver ions in the pH-dependent reaction. This enhanced reactivity is attributed to stabilization by the basic acetate anion of the proton released in the reduction process. The effect of increased pH on the reduction rate is much greater than the specific effects associated with silver-acetate complexing.
Liquid crystal cells with "dirty" substrates

description: We explore liquid crystal order in a cell with a "dirty" substrate imposing a random surface pinning. Modeling such systems by a random-field xy-model with surface heterogeneity, we find that orientational order in the three-dimensional system is marginally unstable to such surface pinning. We compute the Larkin length scale, and the corresponding surface and bulk distortions. On longer scales we calculate correlation functions using the functional renormalization group and matching methods, finding a universal logarithmic and double-logarithmic roughness in two and three dimensions, respectively. For a finite thickness cell, we explore the interplay of homogeneous-heterogeneous substrate pair and detail crossovers as a function of disorder strength and cell thickness.

N$^3$LO Spin-Orbit Interaction via the EFT of Spinning Gravitating Objects

description: We present the derivation of the third subleading order (N$^3$LO) spin-orbit interaction at the state of the art of post-Newtonian (PN) gravity via the EFT of spinning objects. The present sector contains the largest and most elaborate collection of Feynman graphs ever tackled to date in sectors with spin, and in all PN sectors up to third subleading order. Our computations are carried out via advanced multi-loop methods. Their most demanding aspect is the imperative transition to a generic dimension across the whole derivation, due to the emergence of dimensional-regularization poles across all loop orders as of the N$^3$LO sectors. At this high order of sectors with spin, it is also critical to extend the formal procedure for the reduction of higher-order time derivatives of spin variables beyond linear order for the first time. This gives rise to a new unique contribution at the present sector. The full interaction potential in Lagrangian form and the general Hamiltonian are provided here for the first time. The consequent gravitational-wave (GW) gauge-invariant observables are also derived, including relations among the binding energy, angular momentum, and emitted frequency. Complete agreement is found between our results, and the binding energy of GW sources, and also with the extrapolated scattering angle in the scattering problem, derived via traditional GR. In contrast with the latter derivation, our framework is free-standing and generic, and has provided theory and results, which have been critical to establish the state of the art, and to push the precision frontier for the measurement of GWs.

description: We discuss the gravitational lensing of neutrinos by astrophysical objects. Unlike pho-tons, neutrinos can cross a stellar core; as a result, the lens quality improves. We also estimate the depletion of the neutrino flux after crossing a massive object and the signal amplification expected. While Uranians alone would benefit from this effect in the Sun, similar effects could be considered for binary systems.

description: Active and personalized learning requires that teachers can remix a wide variety of sources into new learning resources, which in turn may be customized by students. While this is well-supported for paper-oriented resources, multimodal, interactive learning resources for digital use, called explorables, are much more difficult to author and remix. In this paper, we derive a set of requirements for a system to author such explorables from a workshop-based study. We further present a first prototype of such a system, called “WebWriter”.

description: Supermassive black hole mass estimates are derived for 1743 galaxies from the Millennium Galaxy Catalogue using the recently revised empirical relation between supermassive black hole mass and the luminosity of the host spheroid. The MGC spheroid luminosities are based on $R^{1/n}$-bulge plus exponential-disc decompositions. The majority of black hole masses reside between $10^6 M_{\odot}$ and an upper limit of $2\times10^9 M_{\odot}$. Using previously determined space density weights, we derive the SMBH mass function which we fit with a Schechter-like function. Integrating the black hole mass function over $10^6< M_{bh}/ M_{\odot} < 10^{10}$ gives a supermassive black hole mass density of ($3.8 \pm 0.6) \times 10^5 h^{3}_{70} M_{\odot}$ Mpc$^{-3}$ for early-type galaxies and ($0.96 \pm 0.2) \times10^5 h^{3}_{70} M_{\odot}$ Mpc$^{-3}$ for late-type galaxies. The errors are estimated from Monte Carlo simulations which include the uncertainties in the $M_{bh}$--$L$ relation, the luminosity of the host spheroid and the intrinsic scatter of the $M_{bh}$--$L$ relation. Assuming supermassive black holes form via baryonic accretion we find that ($0.008\pm0.002) h_{70}^{3}$ per cent of the Universe's baryons are currently locked up in supermassive black holes. This result is consistent with our previous estimate based on the $M_{bh}$--$n$ (S{é}rsic index) relation.

description: Bildungstechnologische Systeme, die in zeitlich begrenzten Projekten, konkreten Lehr-veranstaltungen oder individuellen Qualifikationsvorhaben entwickelt werden, sind nicht immer für den universellen Einsatz geeignet. Soll der Einsatz dennoch deutlich über den ursprünglichen Anwendungsbereich hinaus skaliert werden, sind daher möglicherweise grundlegende Änderungen an der Software notwendig. Anhand von Erfahrungen aus der Entwicklung des E-Assessment-Systems JACK diskutiert der Beitrag, wie die systematische Umsetzung von Modularität in der fachlichen Architektur und dem Systemdesign die Skalierbarkeit eines Systems verbessern kann.

description: A transversal in an $n \times n$ latin square is a collection of $n$ entries not repeating any row, column, or symbol. Kwan showed that almost every $n \times n$ latin square has $\bigl((1 + o(1)) n / e^2\bigr)^n$ transversals as $n \to \infty$. Using a loose variant of the circle method we sharpen this to $(e^{-1/2} + o(1)) n!^2 / n^n$. Our method works for all latin squares satisfying a certain quasirandomness condition, which includes both random latin squares with high probability as well as multiplication tables of quasirandom groups.

description: Der Workshop des Arbeitskreises Open Science zielte darauf ab, gemeinsam mit der Fachcommunity mögliche Verfahren zur Begutachtung von Forschungsdaten (inklusive Software) aus dem Kontext Bildungstechnologien zu erörtern. Dazu gehören sowohl die Entwicklung realistischer und nachvollziehbarer Anforderung an die Publikation von Forschungsdaten, als auch Review Richtlinien für zukünftige DELFI Programmkomitees. Weiterhin war es das Ziel, die Vor- und Nachteile neuer Publikationsformate gegeneinander abzuwiegen und zu diskutieren. Methodisch wurde im Workshop vor allem die Diskussion mit den Teilnehmenden angestrebt, sodass die Umsetzbarkeit neuer Anforderungen im Fokus blieb. In dem vorliegenden Beitrag werden die Ergebnisse des halbtägigen Workshops zusammengefasst.

description: Using different experimental techniques combined with density functional based theoretical methods we have explored the formation of interface-stabilized manganese oxide structures grown on Pd(100) at (sub)monolayer coverage. Amongst the multitude of phases experimentally observed we focus our attention on four structures which can be classified into two distinct regimes, characterized by different building blocks. Two oxygen-rich phases are described in terms of MnO(111)-like O-Mn-O trilayers, whereas the other two have a lower oxygen content and are based on a MnO(100)-like monolayer structure. The excellent agreement between calculated and experimental scanning tunneling microscopy images and vibrational electron energy loss spectra allows for a detailed atomic description of the explored models.

description: Wie finden neue, spannende und zugleich herausfordernde Technologien, wie die virtuelle Realität, den Weg in die Hochschullehre? Dieser Beitrag beschreibt ein interdisziplinäres Projekt, das sich genau dieser Frage stellt. Unser Ziel ist es, das Periodensystem der Elemente als einen Verbund virtueller Umgebungen abzubilden, in denen jedes Element seinen eigenen Raum hat. Für jedes Element soll eine eigene Lernumgebung gestaltet werden, die mit Informationen zu den Elementen angereichert ist (z.B. bei Stickstoff die Bildung von Stickoxiden im Autoverkehr oder die Herstellung von Düngemitteln). Dieser Beitrag beschreibt unseren iterativen Ansatz und die Optimierung eines bestehenden ersten Prototyps. Ein iterativer Optimierungsprozess (im Sinne von Design Science Research) trägt dazu bei, dass i) Lernende eine möglichst effektive und positive Erfahrung machen und ii) Lehrende für zukünftige Projekte von den Erfahrungen profitieren und diese auf andere Kontexte übertragen können. Wir präsentieren die Ergebnisse einer Studie mit 40 Beobachtungen, die Lernräume vergleicht, die mit der Mozilla Hubs Plattform erstellt wurden. Die neu gestaltete Lernräume wurden insbesondere unter Berücksichtigung der Prinzipien der Theorie des multimedialen Lernens konzipiert. Die Ergebnisse legen nahe, dass sich durch die Anwendung der Prinzipien der Theorie des multimedialen Lernens der wahrgenommene Lernerfolg signifikant verbessern lässt. Wir möchten den Workshop nutzen, um eine Zusammenarbeit zwischen deutschen Hochschulen zu diskutieren, die eine eigene DSGVO-konforme Mozilla Hubs Instanz hosten und entsprechende Expertise aufbauen.
Cooperative Spectrum Sensing based on the Limiting Eigenvalue Ratio Distribution in Wishart Matrices

description: Recent advances in random matrix theory have spurred the adoption of eigenvalue-based detection techniques for cooperative spectrum sensing in cognitive radio. Most of such techniques use the ratio between the largest and the smallest eigenvalues of the received signal covariance matrix to infer the presence or absence of the primary signal. The results derived so far in this field are based on asymptotical assumptions, due to the difficulties in characterizing the exact distribution of the eigenvalues ratio. By exploiting a recent result on the limiting distribution of the smallest eigenvalue in complex Wishart matrices, in this paper we derive an expression for the limiting eigenvalue ratio distribution, which turns out to be much more accurate than the previous approximations also in the non-asymptotical region. This result is then straightforwardly applied to calculate the decision threshold as a function of a target probability of false alarm. Numerical simulations show that the proposed detection rule provides a substantial performance improvement compared to the other eigenvalue-based algorithms.

description: Im Fokus des Papiers steht die Untersuchung der von greenpeace entwickelten XR-Lernanwendung “Der Artenvielfalt auf der Spur” mit Fokus auf der Umgebung des Amazonas-Regenwaldes. Die Aussagen von acht Fokusgruppen mit Schüler:innen der siebten bis neunten Klasse deutscher Schulen wurden qualitativ ausgewertet. Die Ergebnisse zeigen, dass die Schüler:innen bedeutsam ihr Wissen zu Biodiversität anreichern konnten. Ferner gaben die Schüler:innen an, sich im Nachgang mit assoziierten Inhalten (z.B. Arten- und Klimaschutz) auseinandergesetzt und eigene Verhaltensweisen reflektiert zu haben. In allen Fokusgruppen wurde deutlich, dass die Lernanwendung sowohl die Einstellungs- als auch die Verhaltensebene positiv beeinflussen konnte. Insgesamt wurde die Lernanwendung von den Schüler:innen positiv bewertet, was sie auf die erlebten Lernprozesse wie physische und soziale Präsenz und der Verarbeitung von audio-visuellen Reizen zurückführten.
Anxiety and masculinity-femininity
Creators: name: Pruesse, Manfred Gebhard
Publisher: name: University of British Columbia

description: The primary purpose of the study was to investigate the relationship between anxiety and masculinity-femininity in order to clarify some of the causes of the sex differences found in anxiety. A secondary purpose was to investigate the overt and covert aspects of anxiety in feminine males and masculine females. The sample was composed of 33 male and 38 female university students enrolled in a second year summer school course in psychology. The IPAT Anxiety Scale and the MMPI Mf Scale were administered, in that order, during a regular classroom period. The relationship between the two sets of scores was examined. The 15 most feminine males and the 15 most masculine males were compared with respect to their overt and covert anxiety scores. The same was done with the female subjects. A correlation of 0.26, significant at the 0.01% level, was obtained between the anxiety scores and the Mf scores. Feminine males were overtly and covertly significantly more anxious than masculine males. Feminine females were overtly significantly more anxious than masculine females. However, feminine and masculine females scored approximately equally on the covert anxiety scale. It was concluded that anxiety is associated with femininity. The suggestion was made that it may be some aspect of the female sex role, as delineated by society, that accounts for the higher anxiety in feminine people.

description: Velocity dispersion measurements are presented for luminous GCs in NGC 5128 derived from high-res. UVES spectra. The measurements are made with the pPXF code that parametrically recovers line-of-sight velocity dispersions. Combining the measured velocity dispersions with surface photometry and structural parameter data from HST enables both dynamical masses and M/L ratios to be derived. The fundamental plane relations of these clusters are investigated in order to fill the apparent gap between the relations of Local Group GCs and more massive early-type galaxies. It is found that the properties of these massive stellar systems match those of nuclear clusters in dwarf elliptical galaxies and UCDs better than those of Local Group GCs, and that all objects share similarly old (>8 Gyr) ages, suggesting a possible link between the formation and evolution of dE,Ns, UCDs and massive GCs. We find a very steep correlation between dynamical (M/L) ratio and dynamical mass of the form (M/L)_dyn ~ M_dyn^(0.24+/-0.02) above M_dyn = 2x10^6 Msol. Formation scenarios are investigated with a chemical abundance analysis using absorption line strengths calibrated to the Lick/IDS index system. The results lend support to two scenarios contained within a single general formation scheme. Old, massive, super-solar [alpha/Fe] systems are formed on short (<100 Myr) timescales through the merging of single-collapse GCs which themselves are formed within single, giant molecular clouds. More intermediate- and old-aged (~3-10 Gyr), solar- to sub-solar [alpha/Fe] systems are formed on much longer (~Gyr) timescales through the stripping of dE,Ns in the 10^13-10^15 Msol potential wells of massive galaxies and galaxy clusters.

description: We have performed detailed x-ray scattering measurements on single crystals of the spin-Peierls compound TiOBr in order to study the critical properties of the transition between the incommensurate spin-Peierls state and the paramagnetic state at Tc2 ~ 48 K. We have determined a value of the critical exponent beta which is consistent with the conventional 3D universality classes, in contrast with earlier results reported for TiOBr and TiOCl. Using a simple power law fit function we demonstrate that the asymptotic critical regime in TiOBr is quite narrow, and obtain a value of beta_{asy} = 0.32 +/- 0.03 in the asymptotic limit. A power law fit function which includes the first order correction-to-scaling confluent singularity term can be used to account for data outside the asymptotic regime, yielding a more robust value of beta_{avg} = 0.39 +/- 0.05. We observe no evidence of commensurate fluctuations above Tc1 in TiOBr, unlike its isostructural sister compound TiOCl. In addition, we find that the incommensurate structure between Tc1 and Tc2 is shifted in Q-space relative to the commensurate structure below Tc1.

description: We investigate signal propagation in a quantum field simulator of the Klein-Gordon model realized by two strongly coupled parallel one-dimensional quasi-condensates. By measuring local phononic fields after a quench, we observe the propagation of correlations along sharp light-cone fronts. If the local atomic density is inhomogeneous, these propagation fronts are curved. For sharp edges, the propagation fronts are reflected at the system's boundaries. By extracting the space-dependent variation of the front velocity from the data, we find agreement with theoretical predictions based on curved geodesics of an inhomogeneous metric. This work extends the range of quantum simulations of non-equilibrium field dynamics in general spacetime metrics.

Non-parametric Deprojection of Surface Brightness Profiles of Galaxies in Generalised Geometries

description: We present a new Bayesian non-parametric deprojection algorithm DOPING (Deprojection of Observed Photometry using and INverse Gambit), that is designed to extract 3-D luminosity density distributions $ρ$ from observed surface brightness maps $I$, in generalised geometries, while taking into account changes in intrinsic shape with radius, using a penalised likelihood approach and an MCMC optimiser. We provide the most likely solution to the integral equation that represents deprojection of the measured $I$ to $ρ$. In order to keep the solution modular, we choose to express $ρ$ as a function of the line-of-sight (LOS) coordinate $z$. We calculate the extent of the system along the ${\bf z}$-axis, for a given point on the image that lies within an identified isophotal annulus. The extent along the LOS is binned and density is held a constant over each such $z$-bin. The code begins with a seed density and at the beginning of an iterative step, the trial $ρ$ is updated. Comparison of the projection of the current choice of $ρ$ and the observed $I$ defines the likelihood function (which is supplemented by Laplacian regularisation), the maximal region of which is sought by the optimiser (Metropolis Hastings). The algorithm is successfully tested on a set of test galaxies, the morphology of which ranges from an elliptical galaxy with varying eccentricity to an infinitesimally thin disk galaxy marked by an abruptly varying eccentricity profile. Applications are made to faint dwarf elliptical galaxy Ic~3019 and another dwarf elliptical that is characterised by a central spheroidal nuclear component superimposed upon a more extended flattened component. The result of deprojection of the X-ray image of triaxial cluster A1413 is also presented.

description: Wie können wir Richtlinien für vertrauenswürdige und ethische KI-Nutzung in der Bildung für die Praxis ausarbeiten und einsetzen? Dieses akute und viel besprochene Thema war die Ausgangsfrage des Workshops bei der DELFI-Tagung 2023. In diesem Artikel wird zunächst der aktuelle Hintergrund des Themas erörtert, der auch im Mittelpunkt der thematischen Einführung stand. Anschließend werden Konzeption, Verlauf und Ergebnisse des Workshops hier präsentiert. Dabei haben nach der Einführung und unter der Anleitung und Moderation von Christian M. Stracke 20 Teilnehmende intensiv diskutiert, welche Bedingungen für eine vertrauenswürdige und ethische Nutzung von Künstlicher Intelligenz (KI) in der Bildung gegeben sein sollten und müssen. Als zentrales Ergebnis lässt sich konstatieren, dass die intensiven Austausche und Diskussionen im Workshop die Erkenntnisse und Erfahrungen zu KI bei den Teilnehmenden erhöhten. Der Artikel endet mit einem Ausblick über die fünf Hauptbedingungen der ethischen KI- Nutzung, die als Basis für eine digitale Kompetenzentwicklung zu KI und vor allem für weiteren Forschungen zu ethischen Fragestellungen in der Beziehung von KI und Bildung genutzt werden können.
