description: Wenn Fachwissenschaft und Fachdidaktik gemeinsam tagen, dann lohnt es sich, nach Anknüpfungspunkten zwischen den beiden Disziplinen zu suchen. Ein solcher Anknüpfungspunkt ist der Transfer von Anwendungen aus der aktuellen mathematischen Forschung in den Unterricht und in die Lehrerausbildung. Es gibt zahlreiche moderne Anwendungen der Mathematik, die auf Schulniveau erarbeitet werden können, und die helfen, einen mathematischen Blick auf die Welt zu schulen. Gleichzeitig vermitteln moderne Anwendungen, dass die Mathematik eine lebendige Wissenschaft ist, die im Alltag äußerst präsent ist.

Spatiotemporal Structure of Aeolian Particle Transport on Flat Surface

description: We conduct numerical simulations based on a model of blowing snow to reveal the long-term properties and equilibrium state of aeolian particle transport from $10^{-5} \hspace{0.5 ex} \mathrm{m}$ to $10 \hspace{0.5 ex} \mathrm{m}$ above the flat surface. The numerical results are as follows. (i) Time-series data of particle transport are divided into development, relaxation, and equilibrium phases, which are formed by rapid wind response below $10 \hspace{0.5 ex} \mathrm{cm}$ and gradual wind response above $10 \hspace{0.5 ex} \mathrm{cm}$. (ii) The particle transport rate at equilibrium is expressed as a power function of friction velocity, and the index of 2.35 implies that most particles are transported by saltation. (iii) The friction velocity below $100 \hspace{0.5 ex} μ\mathrm{m}$ remains roughly constant and lower than the fluid threshold at equilibrium. (iv) The mean particle speed above $300 \hspace{0.5 ex} μ\mathrm{m}$ is less than the wind speed, whereas that below $300 \hspace{0.5 ex} μ\mathrm{m}$ exceeds the wind speed because of descending particles. (v) The particle diameter increases with height in the saltation layer, and the relationship is expressed as a power function. Through comparisons with the previously reported random-flight model, we find a crucial problem that empirical splash functions cannot reproduce particle dynamics at a relatively high wind speed.

description: The DeVill project, initiated by the Austrian Society for Medieval and Modern Archaeology, aims to digitise its extensive archive of deserted medieval villages (DMVs), previously managed and significantly contributed to by Kurt Bors, and to make it online accessible. Since its inception in the early 1970s, the archive has grown to encompass a wealth of information, including literature, written sources, cartographic materials, and archaeological findings, primarily about the Federal States of Lower Austria, Burgenland, and Styria. The digitisation effort, catalysed by the challenges of accessing the physical archive and spurred by a grant funded by the state of Austria and the EU, utilises OpenAtlas with a backend structured around CIDOC-CRM to facilitate interdisciplinary research and public engagement. DeVill aims to provide comprehensive online access to these resources, offering detailed site views, digital terrain models, and an interactive map of DMVs, thereby enhancing both academic research and local historical interest.

String Theory - From Physics to Metaphysics

description: Currently, string theory represents the only advanced approach to a unification of all interactions, including gravity. In spite of the more than thirty years of its existence, the sequence of metamorphosis it ran through, and the ever more increasing number of involved physicists, until now, it did not make any empirically testable predictions. Because there are no empirical data incompatible with the quantum field theoretical standard model of elementary particle physics and with general relativity, the only motivations for string theory rest in the mutual incompatibility of the standard model and of general relativity as well as in the metaphysics of the unification program of physics, aimed at a final unified theory of all interactions including gravity. But actually, it is completely unknown which physically interpretable principles could form the basis of string theory. At the moment, ''string theory'' is no theory at all, but rather a labyrinthic structure of mathematical procedures and intuitions which get their justification from the fact that they, at least formally, reproduce general relativity and the standard model of elementary particle physics as low energy approximations. However, there are now strong indications that string theory does not only reproduce the dynamics and symmetries of our standard model, but a plethora of different scenarios with different low energy nomologies and symmetries. String theory seems to describe not only our world, but an immense landscape of possible worlds. So far, all attempts to find a selection principle which could be motivated intratheoretically remained without success. So, recently the idea that the low energy nomology of our world, and therefore also the observable phenomenology, could be the result of an anthropic selection from a vast arena of nomologically different scenarios entered string theory. Although multiverse scenarios and anthropic selection are not only motivated by string theory, but lead also to a possible explanation for the fine tuning of the universe, they are concepts which transcend the framework defined by the epistemological and methodological rules which conventionally form the basis of physics as an empirical science.

description: We theoretically investigate excitons in MoS$_2$ monolayers in an applied in-plane electric field. Tight-binding and Bethe-Salpeter equation calculations predict a quadratic Stark shift, of the order of a few meV for fields of 10 V/$μ$m, in the linear absorption spectra. The spectral weight of the main exciton peaks decreases by a few percent with an increasing electric field due to the exciton field ionization into free carriers as reflected in the exciton wave functions. Subpicosecond exciton decay lifetimes at fields of a few tens of V/$μ$m could be utilized in solar energy harvesting and photodetection. We find simple scaling relations of the exciton binding, radius, and oscillator strength with the dielectric environment and an electric field, which provides a path to engineering the MoS$_2$ electro-optical response.

description: We construct two functors from the submodule category of a self-injective representation-finite algebra $Λ$ to the module category of the stable Auslander algebra of $Λ$. These functors factor through the module category of the Auslander algebra of $Λ$. Moreover they induce equivalences from the quotient categories of the submodule category modulo their respective kernels and said kernels have finitely many indecomposable objects up to isomorphism. Their construction uses a recollement of the module category of the Auslander algebra induced by an idempotent and this recollement determines a characteristic tilting and cotilting module. If $Λ$ is taken to be a Nakayama algebra, then said tilting and cotilting module is a characteristic tilting module of a quasi-hereditary structure on the Auslander algebra. We prove that the self-injective Nakayama algebras are the only algebras with this property.

description: A dense forest of slender bright fibrils near a small solar active region is seen in high-quality narrowband Ca II H images from the SuFI instrument onboard the Sunrise balloon-borne solar observatory. The orientation of these slender Ca II H fibrils (SCF) overlaps with the magnetic field configuration in the low solar chromosphere derived by magnetostatic extrapolation of the photospheric field observed with Sunrise/IMaX and SDO/HMI. In addition, many observed SCFs are qualitatively aligned with small-scale loops computed from a novel inversion approach based on best-fit numerical MHD simulation. Such loops are organized in canopy-like arches over quiet areas that differ in height depending on the field strength near their roots.

Applying polynomial filtering to mass preconditioned Hybrid Monte Carlo

description: The use of mass preconditioning or Hasenbusch filtering in modern Hybrid Monte Carlo simulations is common. At light quark masses, multiple filters (three or more) are typically used to reduce the cost of generating dynamical gauge fields; however, the task of tuning a large number of Hasenbusch mass terms is non-trivial. The use of short polynomial approximations to the inverse has been shown to provide an effective UV filter for HMC simulations. In this work we investigate the application of polynomial filtering to the mass preconditioned Hybrid Monte Carlo algorithm as a means of introducing many time scales into the molecular dynamics integration with a simplified parameter tuning process. A generalized multi-scale integration scheme that permits arbitrary step- sizes and can be applied to Omelyan-style integrators is also introduced. We find that polynomial-filtered mass-preconditioning (PF-MP) performs as well as or better than standard mass preconditioning, with significantly less fine tuning required.

Year: 2023

description: District Heating (DH) systems are one of the most energy efficient heating systems in urban environments, with proven reliability within many decades already. Due to the complexity and size of these energy infrastructures, serving large areas up to thousands dwellings, they need to be understood from a systemic perspective. Dimensions such as engineering (design, operation & maintenance), urban planning, regulations, and stakeholder relations need to be considered in the decarbonization process of these infrastructures, with the aim to decrease the temperature of operation and to increase the share of renewable energy sources and waste heat. This contribution presents the outcomes from relevant DH deployment and retrofit activities within h2020 projects RELaTED and ATELIER.

Revisiting Church Down: experimental reconstructions at Butser Ancient Farm

description: Medieval Settlement Research, 39, 98-104
description: The Mid Saxon settlement at Church Down, Hampshire, is one of the most significant sites of its type; the excavations have never, however, been the subject of a complete published report. Two experimental houses have been constructed at Butser Ancient Farm, Hampshire, each based upon specific archaeology from Church Down. As part of the process, available literature on Church Down was reviewed, which revealed the limited extent of the published material. This paper provides a fresh evaluation of the Church Down settlement through a synthesis of the published papers, updated with material from more recent evaluations of the archaeology and landscape in the environs. It includes an overview of the excavation and site character, an examination of the archaeology on which the Butser buildings are based, and details the interpretation of the archaeology as experimental structures.

description: Gene regulatory network inference is a systems biology approach which predicts interactions between genes with the help of high-throughput data. In this review, we present current and updated network inference methods focusing on novel techniques for data acquisition, network inference assessment, network inference for interacting species and the integration of prior knowledge. After the advance of Next-Generation-Sequencing of cDNAs derived from RNA samples (RNA-Seq) we discuss in detail its application to network inference. Furthermore, we present progress for large-scale or even full-genomic network inference as well as for small-scale condensed network inference and review advances in the evaluation of network inference methods by crowdsourcing. Finally, we reflect the current availability of data and prior knowledge sources and give an outlook for the inference of gene regulatory networks that reflect interacting species, in particular pathogen-host interactions.

description: Dark matter (DM) halos have long been known to be triaxial, but in studies of possible annihilation and decay signals they are often treated as approximately spherical. In this work, we examine the asymmetry of potential indirect detection signals of DM annihilation and decay, exploiting the large statistics of the hydrodynamic simulation Illustris. We carefully investigate the effects of the baryons on the sphericity of annihilation and decay signals for both the case where the observer is at 8.5 kpc from the center of the halo (exemplified in the case of Milky Way-like halos), and for an observer situated well outside the halo. In the case of Galactic signals, we find that both annihilation and decay signals are expected to be quite symmetric, with axis ratios very different from 1 occurring rarely. In the case of extragalactic signals, while decay signals are still preferentially spherical, the axis ratio for annihilation signals has a much flatter distribution, with elongated profiles appearing frequently. Many of these elongated profiles are due to large subhalos and/or recent mergers. Comparing to gamma-ray emission from the Milky Way and X-ray maps of clusters, we find that the gamma-ray background appears less spherical/more elongated than the expected DM signal from the large majority of halos, and the Galactic gamma ray excess appears very spherical, while the X- ray data would be difficult to distinguish from a DM signal by elongation/sphericity measurements alone.

description: The dynamic behavior of powdered materials such as granular silica (sand), technical ceramics, and porous geological substances has importance to a variety of engineering applications. Structural seismic coupling, planetary science, earth penetration mechanics, and the performance of ceramic armors are just some of application areas. Although the mechanical behaviors of sand and other granular ceramics have been studied extensively for several decades, the dynamic behavior over a range of strain rates and pressures of such materials remains poorly understood. This paper describes how instrumented electromagnetic tube compression driven by capacitive discharge can be used to measure compaction of porous materials at moderate pressures and controlled strain rates. The technique relies on electromagnetically crushing a powder-filled conductive tube. By measuring the current as a function of time and the tube displacement through Photon Doppler Velocimetry (PDV) sufficient data can be obtained to reveal the behavior of the porous material. The method will be described in detail and example data will be shown for compaction of silica sand.
Bulk Locality and Entanglement Swapping in AdS/CFT

description: Localized bulk excitations in AdS/CFT are produced by operators which modify the pattern of entanglement in the boundary state. We show that simple models--consisting of entanglement swapping operators acting on a qubit system or a free field theory--capture qualitative features of gravitational backreaction and reproduce predictions of the Ryu-Takayanagi formula. These entanglement swapping operators naturally admit multiple representations associated with different degrees of freedom, thereby reproducing the code subspace structure emphasized by Almheiri, Dong, and Harlow. We also show that the boundary Reeh-Schlieder theorem implies that equivalence of certain operators on a code subspace necessarily breaks down when non-perturbative effects are taken into account (as is expected based on bulk arguments).

description: We study the dynamic critical phenomena near the possible high-density QCD critical point inside the superfluid phase of nuclear and quark matter. We find that this critical point belongs to a new dynamic universality class beyond the conventional classification by Hohenberg and Halperin. We show that the speed of the superfluid phonon vanishes at the critical point and that the dynamic critical index is $z \approx 2$.

description: In this work we combine two structuring methods for the production of nanostructures. For this purpose a new collaboration was launched between the TU Dortmund and the company Raith GmbH, supplier of nanofabrication tools. The first method is the fabrication of nanometer sized pits on graphite which was performed in our group before. These pits were used to produce metal clusters with a narrow size distribution. The second method is the fabrication of predefined structures with a beam of focused gallium ions. With this almost any pattern can be structured on any sample. The tool used here for this purpose is a new development of Raith (Raith ‘ionLiNE’). Within this thesis the applicability of this method was tested and new applications were found. The fabrication of nanostructures with feature sizes smaller than 50 nm is presented. These nano-structures were then used for the controlled growth of metal clusters, e.g. a pattern of single lead clusters with 100 nm pitch. New and special properties of the metal clusters (silver and lead) were observed. Another topic in this work is the structuring of graphite layers, called graphene. In the last years the interest in this material arose particularly because of its special electronic properties. It will be shown that we are able to produce corresponding structures with our method. The structures are mainly investigated with a low temperature ultra high vacuum scanning tunneling microscope (STM). The experiments are combined with Monte Carlo simulations for a better understanding of the results.
Karma in the community

description: In the face of pervasive information and communication technologies (ICT), we must refine understanding of our values and the concept of ‘property’ as a fundamental form of stored value. This series of papers extends the concept of karma in the face of collectives with networked communications and automata. We conclude that we have entered a situation beyond privacy, where to protect the ‘right’ to conscious thought itself, governance and regulation of automation and global properties of community networks become essential. One paper describes a model that represents the ancient concept of karma in the context of modern neuroscience and psychology, supporting the view that karma is fundamentally a property of each individual. A sister paper extends the model of karma in the face of modern automation and communication to identify a new form, ‘WE-karma’, that depends on the nature of the collective, rather than that of individuals or their local interactions. Using this framework, we argue that individuals must adopt automation to balance the asymmetry by supplementing their innate capacity for mental simulation with external simulations. This scenario naturally gives rise to the question:
 How does governance encourage and support their fulfilling this aim?

description: Are national technology and innovation policies becoming obsolete under the conditions of an increasing internationalization of science, technologies and industry? The paper supports the argument that despite globalization and Europeanization, national technology and innovation policies remain the most important and effective level of governance in this area of policy. The argument will be elaborated in four steps: firstly, the paper presents a brief overview of the discussions and controversy concerning the future governance of technology and innovation policies. Secondly, the effects of changing general conditions on national policies are discussed, especially the policy implications of the development of new technologies, of the internationalization of industry and of the growing importance of public discourses. Thirdly, the relations between the national and the European level of governance are analyzed and an answer is given to the question why there has not been a significant shift of competencies and resources from the national to the European level until now. Against this background and with a special view regarding the German case, the paper finally analyses strategic reorientations, new elements and instruments of the national technology and innovation policy and discusses their impact on science, industry, and society.

description: The present study was undertaken to investigate the hepatoprotective effect of pantothenic acid on CCl4-induced liver damage. Male Wistar rats were orally treated with pantothenic acid (0.005, 0.01, 0.025, 0.05 and 0.1 g/kg) daily, with administration of CCl4 (1 mL/kg, 50 % CCl4 in olive oil) twice a week for 28 days. The effect of pantothenic acid on serum markers (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and gamma-glutamyltransferase)was measured in CCl4-induced hepatotoxicity in rat. Further, the effects on enzymatic antioxidant (superoxide dismutase) were estimated in the liver samples. CCl4 challenge not only elevated the serum marker enzyme activities but also suppressed hepatic antioxidative defense system including superoxide dismutase. The biochemical observations were supplemented with histopathological examination of rat liver sections. Histopathological examination of livers showed that pantothenic acid reduced fatty degeneration, cytoplasmic vacuolization and necrosis in CCl4-treated rats. Therefore, pantothenic acid may be an effective hepatoprotective agent and viable candidate for treating hepatic disorders and other oxidative stress-related diseases.

description: The substitutability of inputs to health production in hospitals has recently become an issue in Germany. New regulations concerning the renumeration of hospitals set incentives to reduce patients’ length of stay and, in turn, to operate less care-intensive. Based on data at the individual hospital level from Germany, covering the years 2006 to 2008, we test whether substitutability of inputs and its change over time exhibits heterogeneity across different types of ownership. If found in the data, this may point at differently owned hospitals adapting differently to the new regulations. In order to avoid relying on input prices as regressors, which exhibit only very limited variation across hospitals, we pursue a price-free empirical approach by calculating technical elasticities of substitution from the multiplier representation of data envelopment analysis. The empirical analysis yields pronounces ownership-specific heterogeneity in the technical elasticity of substitution between physicians and nurses indicating that non-profit hospitals operate particularly ‘physician-intensive’. Yet, this pattern is stable over the considered period.
