description: Im Fach Mathematik ist die Transition von der Schule zur Hochschule insbesondere durch einen Übergang von der Sprache im Mathematikunterricht hin zur mathematischen Sprache an der Hochschule gekennzeichnet. Während in der Schulmathematik oftmals (umgangssprachliche) Umschreibungen genügen, wird von den Studierenden an der Universität eine korrekte und präzise Verwendung der mathematischen Sprache gefordert, d. h. sie werden neben neuen sprachlichen Elementen auch mit neuen Normen zur Verwendung der mathematischen Sprache konfrontiert (Reiss & Nagel, 2017). Dabei zeigen Untersuchungen, dass dies viele Studierende gerade zu Beginn ihres Mathematikstudiums vor Probleme stellt, weshalb Clark und Lovric (2008, S. 29) auch von einem „shock of passage from informal to formal language“ sprechen und die mathematische Sprache auch als „gatekeeper“ gesehen werden kann, um Zugang zur mathematischen Community zu erhalten (u. a. Guedet, 2008). Ziel unseres im khdm verankerten Forschungsprojektes ist es deshalb, den Transitionsprozess hinsichtlich der mathematischen Sprache genauer zu untersuchen und insbesondere den Fragen nachzugehen, welche konkreten sprachlichen Schwierigkeiten sich für Studierende ergeben und wie sich diese im ersten Studienjahr entwickeln. In diesem Beitrag soll der Fokus dabei auf Schwierigkeiten von Studienanfänger*innen im Fach Mathematik beim schriftlichen Gebrauch der mathematischen Sprache liegen.

description: Recent developments in the categorical foundations of universal algebra have given fresh impetus to an understanding of the lambda calculus coming from categorical logic: an interpretation is a semi-closed algebraic theory. Scott's representation theorem is then completely natural and leads to precise theorems showing the essential equivalence with more familiar notions. Simple abstract proofs of fundamental results in the semantics of the lambda calculus are given.

description: We study two-color QCD with two flavors of Wilson fermion as a function of quark chemical potential mu and temperature T. We find evidence of a superfluid phase at intermediate mu and low T where the quark number density and diquark condensate are both very well described by a Fermi sphere of nearly-free quarks disrupted by a BCS condensate. Our results suggest that the quark contribution to the energy density is negative (and balanced by a positive gauge contribution), although this result is highly sensitive to details of the energy renormalisation. We also find evidence that the chiral condensate in this region vanishes in the massless limit. This region gives way to a region of deconfined quark matter at higher T and mu, with the deconfinement temperature, determined from the renormalised Polyakov loop, decreasing only very slowly with increasing chemical potential. The quark number susceptibility chi_q does not exhibit any qualitative change at the deconfinement transition. We argue that this is because chi_q is not an appropriate measure of deconfinement for 2-color QCD at high density.

description: We extend the lowest-order matching of tree-level matrix elements with parton showers to give a complete description at the next higher perturbative accuracy in alpha_s at both small and large jet resolutions, which has not been achieved so far. This requires the combination of the higher-order resummation of large Sudakov logarithms at small values of the jet resolution variable with the full next-to-leading order (NLO) matrix-element corrections at large values. As a by-product this combination naturally leads to a smooth connection of the NLO calculations for different jet multiplicities. In this paper, we focus on the general construction of our method and discuss its application to e+e and pp collisions. We present first results of the implementation in the GENEVA Monte Carlo framework, where we employ N-jettiness as the jet resolution variable, combining its next-to-next-to-leading logarithmic resummation with fully exclusive NLO matrix elements, and PYTHIA8 as the backend for further parton showering and hadronization. For hadronic collisions, we take Drell-Yan production as an example to apply our construction. For e+e- -> jets, taking alpha_s(mZ) = 0.1135 from fits to LEP thrust data, together with the PYTHIA8 hadronization model, we obtain good agreement with LEP data for a variety of 2-jet observables.

The theory of Pratityasamutpada and the theory of causality prove the reason for the deterioration in the quality of the environment is the excessive materialistic tendency of man. On this basis, let's accept the point of change in human attitude towards nature. The principle of causality of Buddhist philosophy is the cornerstone of environmental protection.

description: We present a calculation of two-point correlation functions of the stress-energy tensor in the strongly-coupled, confining gauge theory which is holographically dual to the AdS soliton geometry. The fact that the AdS soliton smoothly caps off at a certain point along the holographic direction, ensures that these correlators are dominated by quasinormal mode contributions and thus show an exponential decay in position space. In order to study such a field theory on a curved spacetime, we foliate the six-dimensional AdS soliton with a Schwarzschild black hole. Via gauge/gravity duality, this new geometry describes a confining field theory with supersymmetry breaking boundary conditions on a non-dynamical Schwarzschild black hole background. We also calculate stress-energy correlators for this setting, thus demonstrating exponentially damped heat transport. This analysis is valid in the confined phase. We model a deconfinement transition by explicitly demonstrating a classical instability of Gregory-Laflamme-type of this bulk spacetime.

description: We analyze the stable isomorphism type of polynomial rings on degree 1 generators as modules over the sub-algebra A(1) = of the mod 2 Steenrod algebra. Since their augmentation ideals are Q_1-local, we do this by studying the Q_i-local subcategories and the associated Margolis localizations. The periodicity exhibited by such modules reduces the calculation to one that is finite. We show that these are the only localizations which preserve tensor products, by first computing the Picard groups of these subcategories and using them to determine all idempotents in the stable category of bounded-below A(1)-modules. We show that the Picard groups of the whole category are detected in the local Picard groups, and show that every bounded-below A(1) -module is uniquely expressible as an extension of a Q_0-local module by a Q_1-local module, up to stable equivalence. Applications include correct, complete proofs of Ossa's theorem, applications to Powell's work describing connective K-theory of classifying spaces of elementary abelian groups in functorial terms, and Ault's work on the hit problem.

The induced gravitational collapse scenario proposes a binary progenitor to explain the time-sequence in GRBs-SNe. We show the existence of a common behavior of the late decay of the X-ray afterglow emission of this subclass of GRBs, pointing to a common physical mechanism of their late emission, consistent with the IGC picture.

description: The pi-Lambda-N - pi-Sigma-N coupled-channel system with quantum numbers (Y,I,JP) = (1,3/2,2+) is studied in a relativistic three-body model, using two-body separable interactions in the dominant p-wave pion-baryon and 3S1 YN channels. Three-body equations are solved in the complex energy plane to search for quasibound-state and resonance poles, producing a robust narrow pi-Lambda-N resonance about 10 - 20 MeV below the pi-Sigma-N threshold. Viewed as a dibaryon, it is a 5S2 quasibound state consisting of Sigma(1385)-N and Delta(1232)-Y components. Comparison is made between the present relativistic model calculation and a previous, outdated nonrelativistic calculation which resulted in a pi-Lambda-N bound state. Effects of adding a Kbar-N-N channel are studied and found insignificant. Possible production and decay reactions of this (Y,I,JP)=(1,3/2,2+) dibaryon are discussed.

description: Logistic Gaussian process (LGP) priors provide a flexible alternative for modelling unknown densities. The smoothness properties of the density estimates can be controlled through the prior covariance structure of the LGP, but the challenge is the analytically intractable inference. In this paper, we present approximate Bayesian inference for LGP density estimation in a grid using Laplace's method to integrate over the non-Gaussian posterior distribution of latent function values and to determine the covariance function parameters with type-II maximum a posteriori (MAP) estimation. We demonstrate that Laplace's method with MAP is sufficiently fast for practical interactive visualisation of 1D and 2D densities. Our experiments with simulated and real 1D data sets show that the estimation accuracy is close to a Markov chain Monte Carlo approximation and state-of-the-art hierarchical infinite Gaussian mixture models. We also construct a reduced-rank approximation to speed up the computations for dense 2D grids, and demonstrate density regression with the proposed Laplace approach.

description: The ARCADE 2 collaboration has reported a significant excess in the isotropic radio background, whose homogeneity cannot be reconciled with clustered sources. This suggests a cosmological origin prior to structure formation. We investigate several potential mechanisms and show that injection of relativistic electrons through late decays of a metastable particle can give rise to the observed excess radio spectrum through synchrotron emission. However, constraints from the cosmic microwave background (CMB) anisotropy, on injection of charged particles and on the primordial magnetic field, present a challenge. The simplest scenario is with a >~ 9 GeV particle decaying into e+e- at a redshift of z ~ 5, in a magnetic field of ~ 5 microgauss, which exceeds the CMB B-field constraints, unless the field was generated after decoupling. Decays into exotic millicharged particles can alleviate this tension, if they emit synchroton radiation in conjunction with a sufficiently large background magnetic field of a dark U(1)' gauge field.

description: OBJECTIVE: To compare rates and trends of HIV diagnoses among Indigenous peoples in Canada (First Nations, Métis, Inuit, and other non-specified), Australia (Aboriginal and Torres Strait Islanders), the USA (American Indian, Alaska Native, Native Hawaiian, and Other Pacific Islanders), and New Zealand (Māori). DESIGN: We employed publicly available surveillance data from 2009 to 2017 to estimate the rate per 100 000 of HIV diagnoses. Estimated annual percentage change (EAPC) in diagnosis rates was calculated using Poisson regression. SETTING: The four countries have passive population-based HIV surveillance programs. PARTICIPANTS: Population estimates from respective census programs were used as rate denominators. MAIN OUTCOME MEASURES: Estimated annual HIV diagnosis rate per 100 000 and EAPC were calculated for total Indigenous peoples, women, and men. RESULTS: As of 2017, rates of HIV were highest in Canada (16.22, 95% confidence interval (CI): 14.30--18.33) and lowest in New Zealand (1.36, 95% CI: 0.65--2.50). Australia had a rate of 3.81 (95% CI: 2.59--5.40) and the USA 3.22 (95% CI: 2.85--3.63). HIV diagnosis rates among the total Indigenous population decreased in Canada (-7.92 EAPC, 95% CI: -9.34 to -6.49) and in the USA (-4.25 EAPC, 95% CI: -5.75 to -2.73) but increased in Australia (5.10 EAPC, 95% CI: 0.39--10.08). No significant trends over time were observed in New Zealand (2.23 EAPC, 95% CI: -4.48 to 9.47). CONCLUSION: Despite limitations to conducting cross-national comparisons, there are substantial differences in HIV diagnosis rates in these four countries that may be reflective of divergent national policies and systems that affect the health status of Indigenous peoples.
Small-N Collisional Dynamics: Pushing Into the Realm of Not-So-Small-N

description: In this paper, we study small-N gravitational dynamics involving up to six objects. We perform a large suite of numerical scattering experiments involving single, binary, and triple stars. This is done using the FEWBODY numerical scattering code, which we have upgraded to treat encounters involving triple stars. We focus on outcomes that result in direct physical collisions between stars, within the low angular momentum and high absolute orbital energy regime. The dependence of the collision probability on the number of objects involved in the interaction, N, is found for fixed total energy and angular momentum. Our results are consistent with a collision probability that increases approximately as N^2. Interestingly, this is also what is expected from the mean free path approximation in the limit of very large N. A more thorough exploration of parameter space will be required in future studies to fully explore this potentially intriguing connection. This study is meant as a first step in an on-going effort to extend our understanding of small-N collisional dynamics beyond the three- and four-body problems and into the realm of larger-N.

Many-body properties of quasi-one dimensional Boson gas across a narrow CIR

description: We study strong interaction effects in a one-dimensional (1D) Boson gas across a narrow confinement induced resonance (CIR). In contrast to the zero range potential, the 1D two-body interaction in the narrow CIR can be written as a polynomial of derivative $δ$-function interaction on many-body level. Using the asymptotic Bethe ansatz, we find that the low energy physics of this many-body problem is described by the Tomonaga-Luttinger liquid where the Luttinger parameters are essentially modified by an effective finite range parameter $v$. This parameter drastically alters quantum criticality and universal thermodynamics of the gas. In particular, it drives the Tonks-Girardeau (TG) gas from non-mutual Fermi statistics to mutual statistics or to a more exclusive super TG gas. This novel feature is further discussed in terms of the breathing mode which is experimentally measurable.

description: 75As NMR measurements were performed as a function of temperature and doping in (Eu1-xKx)Fe2As2 (x=0,0.38,0.5,0.7) samples. The large Eu2+ moments and their fluctuations are found to dominate the 75As NMR properties. The 75As nuclei close to the Eu2+ moments likely have a very short spin-spin relaxation time (T2) and are wiped out of our measurement window. The 75As nuclei relatively far from Eu2+ moments are probed in this study. Increasing the Eu content progressively decreases the signal intensity with no signal found for the full-Eu sample (x=0). The large 75As NMR linewidth arises from an inhomogeneous magnetic environment around them. The spin lattice relaxation rate (1/T1) for x=0.5 and 0.7 samples is nearly independent of temperature above 100K and results from a coupling to paramagnetic fluctuations of the Eu2+ moments. The behavior of 1/T1 at lower temperatures has contributions from the antiferromagnetic fluctuations of the Eu2+ moments as also the fluctuations intrinsic to the FeAs planes and from superconductivity.

Existence of a weak solution to a nonlinear fluid-structure interaction problem modeling the flow of an incompressible, viscous fluid in a cylinder with deformable walls

description: We study a nonlinear, unsteady, moving boundary, fluid-structure interaction (FSI) problem arising in modeling blood flow through elastic and viscoelastic arteries. The fluid flow, which is driven by the time-dependent pressure data, is governed by 2D incompressible Navier-Stokes equations, while the elastodynamics of the cylindrical wall is modeled by the 1D cylindrical Koiter shell model. Two cases are considered: the linearly viscoelastic and the linearly elastic Koiter shell. The fluid and structure are fully coupled (2-way coupling) via the kinematic and dynamic lateral boundary conditions describing continuity of velocity (the no-slip condition), and balance of contact forces at the fluid-structure interface. We prove existence of weak solutions to the two FSI problems (the viscoelastic and the elastic case) as long as the cylinder radius is greater than zero. The proof is based on a novel semi-discrete, operator splitting numerical scheme, known as the kinematically coupled scheme, introduced in \cite{GioSun} to solve the underlying FSI problems. The backbone of the kinematically coupled scheme is the well-known Marchuk-Yanenko scheme, also known as the Lie splitting scheme. We effectively prove convergence of that numerical scheme to a solution of the corresponding FSI problem.

description: We study the evolution of quantum fluctuations in the Glasma created immediately after the collision of heavy nuclei. It is shown how the presence of instabilities leads to an enhancement of non-linear interactions among initially small fluctuations. The non-linear dynamics leads to an enhanced growth of fluctuations in a large momentum region exceeding by far the originally unstable band. We investigate the dependence on the coupling constant at weak coupling using classical statistical lattice simulations for SU(2) gauge theory and show how these non-linearities can be analytically understood within the framework of two-particle irreducible (2PI) effective action techniques. The dependence on the coupling constant is only logarithmic in accordance with analytic expectations. Concerning the isotropization of bulk quantities, our results indicate that the system exhibits an order-one anisotropy on parametrically large time scales. Despite this fact, we find that gauge invariant pressure correlation functions seem to exhibit a power law behavior characteristic for wave turbulence.

description: The LHCb Collaboration has recently observed two narrow baryon resonances with beauty. Their masses and decay modes look consistent with the quark model orbitally excited states Lambda_b(5912) and Lambda*_b(5920), with quantum numbers J^P=1/2^- and 3/2^-, respectively. We predict the existence of these states within a unitarized meson-baryon coupled-channel dynamical model, which implements heavy-quark spin symmetry. Masses, quantum numbers and couplings of these resonances to the different meson-baryon channels are obtained. We find that the resonances Lambda^0_b(5912) and Lambda^0_b(5920) are heavy-quark spin symmetry partners, which naturally explains their approximate mass degeneracy. Corresponding bottom-strange baryon resonances are predicted at Xi_b(6035.4) (J^P=1/2^-) and Xi_b(6043.3) (J^P=3/2^-). The two Lambda_b and two Xi_b resonances complete a multiplet of SU(3)-flavor times heavy-quark spin symmetry.

description: This report summarizes the February 15 - March 5, 2012 cruise on the NOAA Ship Ronald H. Brown involving full-water-column CTD, lowered ADCP, and shipboard ADCP profiles conducted within the Florida Straits and east of Abaco Island, Bahamas. At each station, a package consisting of a Seabird Electronics Model 9/11+ CTD O2 system, an RDI 150 kHz Workhorse Lowered Acoustic Doppler Current Proler, a RDI 300 kHz Workhorse Lowered Acoustic Doppler Current Profiler, and 24 10-liter Niskin bottles, was to be lowered to the bottom. This report includes a description of the calibrations procedures and profiles of pressure, salinity (conductivity), temperature, and dissolved oxygen concentration. Water samples were also collected at various depths and analyzed for salinity and oxygen concentration to aid with CTD calibration. A total of 59 CTD-O2/LADCP stations were occupied and PIES data was downloaded from 5 sites. Mooring operations include recovery and redeployment of four tall moorings with a mixture of microcats and current meters, and five short moorings including a short upward looking ADCP mooring, a 400 m mooring with microcats and current meters, and three bottom landers instrumented with bottom pressure recorders. As part of NOAA contribution to the Global Surface Drifter Program, 15 surface velocity drifters equipped with sea-surface temperature sensors were deployed. A total of 48 XBTs were deployed in 24 simultaneous deployments (for Lockheed Martin/Sippican instrument development testing). Nine stations in the Florida Straits along 27N were occupied with 10-minute neuston net tows (in collaboration with John Lamkin, Southeast Fisheries Science Center)

Subjects: DFNS 2023

description: In der Bundesverwaltung liegt eine Vielzahl von Informationen zu sozialen, wirtschaftlichen und umweltbezogenen Themen vor. Politik, Wirtschaft und Gesellschaft sind zunehmend interessiert an kleinräumigen Auswertungen dieser Daten. Um Daten mit unterschiedlichen räumlichen Bezugseinheiten gemeinsam nutzen zu können, wird eine einheitliche Grundeinheit benötigt, auf die alle Inhalte bezogen werden können. Aus diesem Grund wurde im Projekt Gitterzellendatenbank das INSPIRE 100-Meter-Gitter als Bezugseinheit genutzt. So wurden beispielsweise Informationen zu Erreichbarkeiten von Schulen, Kindertages-einrichtungen und Einrichtungen der Gesundheitsversorgung mit dem 100-Meter-Gitter verschnitten. Die Erreichbarkeit bestimmter Einrichtungen spielt unter anderem beim Thema „Gleichwertige Lebensverhältnisse in Stadt und Land“ eine große Rolle. Mit der Gitterzellendatenbank werden Erreichbarkeiten zu verschiedenen Zielen für Fußgänger und für PKW berechnet. Das beantwortet Fragen wie „Wie viele Schulen kann ich innerhalb von zehn Minuten zu Fuß oder mit dem Auto erreichen?“ Im Projekt wurden die verschiedenen Prozessschritte der Berechnung weitestgehend automatisiert: Vom Hochladen der Point of Interest (POI), über die Berechnung der Erreichbarkeiten, bis zum Download der Ergebnisse und Bereitstellung der Metadaten. Zudem wurden Eingabemasken für die Berechnung der benötigten Parameter erstellt. Außerdem wurden die Gitterzellendatenbank und ihre Prozesse in die IT-Infrastruktur des Bundesamtes für Kartographie und Geodäsie (BKG) und des Statistischen Bundesamtes integriert. Das BKG hat initial für 15 POI-Themen Erreichbarkeiten berechnet und somit eine umfangreiche Datengrundlage zum Thema Erreichbarkeitsanalysen für die Bundesverwaltung geschaffen. Die Daten sind als Comma seperated values (CSV) und z. T. als Web Map Service (WMS) im Dienstleistungszentrum des BKG verfügbar. Das BKG plant, die Erreichbarkeiten jährlich zu aktualisieren. Die entwickelte Software wird unter der European Public License V1.2 offen zur Verfügung gestellt. Das Projekt wurde unter dem Call ESTAT-2020-PA8-S-E-GEOS von der Europäischen Statistikbehörde (Eurostat) gefördert. Das Statistische Bundesamt übernahm die Projektleitung, das BKG hat die Entwicklungsarbeiten übernommen und das Thünen-Institut begleitete die Entwicklung wissenschaftlich.

description: Physicists are engaged in vigorous debate on the nature of the quantum critical points (QCP) governing the low-temperature properties of heavy-fermion (HF) metals. Recent experimental observations of the much-studied compound YbRh2Si2 in the regime of vanishing temperature incisively probe the nature of its magnetic-field-tuned QCP. The jumps revealed both in the residual resistivity rho_0 and the Hall resistivity R_H, along with violation of the Wiedemann-Franz law, provide vital clues to the origin of such non-Fermi-liquid behavior. The empirical facts point unambiguously to association of the observed QCP with a fermion-condensation phase transition. Based on this insight, the resistivities rho_0 and R_H are predicted to show jumps at the crossing of the QCP produced by application of a magnetic field, with attendant violation of the Wiedemann-Franz law. It is further demonstrated that experimentally identifiable multiple energy scales are related to the scaling behavior of the effective mass of the quasiparticles responsible for the low-temperature properties of such HF metals.

The nuclear electric polarizability of 6He

description: We present an estimate of the nuclear electric polarizability of the 6He halo nucleus based on six-body microscopic calculations. Wave functions are obtained from semi-realistic two-body interactions using the hyperspherical harmonics expansion method. The polarizability is calculated as a sum rule of the dipole response function using the Lanczos algorithm and also by integrating the photo-absorption cross section calculated via the Lorentz integral transform method. We obtain alpha_E=1.00(14) fm^3, which is much smaller than the published value 1.99(40) fm^3 extracted from experimental data. This points towards a potential disagreement between microscopic theories and experimental observations.

Hot accretion flow in black hole binaries: a link connecting X-rays to the infrared

description: Multiwavelength observations of Galactic black hole transients have opened a new path to understanding the physics of the innermost parts of the accretion flows. While the processes giving rise to their X-ray continuum have been studied extensively, the emission in the optical and infrared (OIR) energy bands was less investigated and remains poorly understood. The standard accretion disc, which may contribute to the flux at these wavelengths, is not capable of explaining a number of observables: the infrared excesses, fast OIR variability and a complicated correlation with the X-rays. It was suggested that these energy bands are dominated by the jet emission, however, this scenario does not work in a number of cases. We propose here an alternative, namely that most of the OIR emission is produced by the extended hot accretion flow. In this scenario, the OIR bands are dominated by the synchrotron radiation from the non-thermal electrons. An additional contribution is expected from the outer irradiated part of the accretion disc heated by the X-rays. We discuss properties of the model and compare them to the data. We show that the hot-flow scenario is consistent with many of the observed spectral data, at the same time naturally explaining X-ray timing properties, fast OIR variability and its correlation with the X-rays.

description: Analytical formulas for some useful three-particles integrals are derived. Many of these integrals include Bessel and/or trigonometric functions of one and two interparticle (relative) coordinates $r_{32}, r_{31}$ and $r_{21}$. The formulas obtained in such an analysis allow us to consider three-particle integrals of more complicated functions of relative/perimetric coordinates. In many actual problems such three-particle integrals can be found in matrix elements of the Hamiltonian and other operators.
