description: Most real world processes are heavily influenced by environmental factors, which are referred to as the context of a process. Thus, the consideration of context is proposed within the research strand of Business Process Modeling. Most existing context-aware modeling approaches con-sider context only in terms of static information like, for instance, the location where a process is performed. However, context information like the weather could change during the conduction of a process, which we will denote as non-static context information. In order to increase the flexibility concerning environmental influences in general and especially context-related events of context-aware processes, we present an approach for the automated planning of context-aware process models that considers static and non-static context information. We therefore propose an extended state transition system in order to represent context information in terms of context variables and consider process exogenous changes of these context variables through context signals and receive context actions. Further, to ensure a correct, complete and time effi-cient construction of context-aware process models, a planning approach is used to support modelers by means of an algorithm. To demonstrate the feasibility of our approach we mathe-matically evaluated the algorithm and applied it to real world processes.

description: We discuss an electronic interferometer recently measured by Yamamoto et al. This "flying quantum bit" experiment showed quantum oscillations between electronic trajectories of two tunnel-coupled wires connected via an Aharanov-Bohm ring. We present a simple scattering model as well as a numerical microscopic model to describe this experiment. In addition, we present new experimental data to which we confront our numerical results. While our analytical model provides basic concepts for designing the flying qubit device, we find that our numerical simulations allow to reproduce detailed features of the transport measurements such as in-phase and anti-phase oscillations of the two output currents as well as a smooth phase shift when sweeping a side gate. Furthermore, we find remarkable resemblance for the magneto conductance oscillations in both conductance and visibility between simulations and experiments within a specific parameter range.

description: We present an overview of the quantitative theory of single-copy entanglement in finite-dimensional quantum systems. In particular we emphasize the point of view that different entanglement measures quantify different types of resources which leads to a natural interdependence of entanglement classification and quantification. Apart from the theoretical basis, we outline various methods for obtaining quantitative results on arbitrary mixed states.

description: A new data-based charge exchange model of GEANT4 dedicated to the $^{9}$Be(p,n)$^{9}$B reaction is developed by taking the ENDF/B-VII.1 differential cross-section data as input. Our model yields results that are in good agreement with the experimental neutron yield spectrum data obtained for proton beams of energy $(20\sim35)$ MeV. In particular, in contrast to all the considered GEANT4 hadronic models, the peak structure resulting from the discrete neutrons generated by the charge-exchange reaction is observed to be accurately reproduced in our model.

description: We study the Sharma-Parthasarathy stochastic two-body problem introduced by N. Sharma and H. Parthasarathy in \cite{sharma}. In particular, we focus on the preservation of some fundamental features of the classical two-body problem like the Hamiltonian structure and first integrals in the stochastic case. Numerical simulations are performed which illustrate the dynamical behaviour of the osculating elements as the semi-major axis, the eccentricity and the pericenter. We also derive a stochastic version of Gauss's equations in the planar case.

description: Identical particles and entanglement are both fundamental components of quantum mechanics. However, when identical particles are condensed in a single spatial mode, the standard notions of entanglement, based on clearly identifiable subsystems, break down. This has led many to conclude that such systems have limited value for quantum information tasks, compared to distinguishable particle systems. To the contrary, we show that any entanglement formally appearing amongst the identical particles, including entanglement due purely to symmetrization, can be extracted into an entangled state of independent modes, which can then be applied to any task. In fact, the entanglement of the mode system is in one-to-one correspondence with the entanglement between the inaccessible identical particles. This settles the long-standing debate about the resource capabilities of such states, in particular spin-squeezed states of Bose-Einstein condensates, while also revealing a new perspective on how and when entanglement is generated in passive optical networks. Our results thus reveal new fundamental connections between entanglement, squeezing, and indistinguishability.

title: Die Anfänge der Militär-Sanitäts-Statistik in der Habsburgermonarchie ab 1870
Creators: name: Zeilinger, Reinhard
Year: 2023

description: In dieser Arbeit werden mehrere historische Entwicklungen der Militär-Sanitäts-Statistik und von Infektionskrankheiten im Zusammenhang mit Sanitäts- und Medizinentwicklung im 19. Jahrhundert nachgezeichnet. Diese Entwicklung wird dargestellt anhand der Anfangsjahre der militär-statistischen Jahrbücher, die eine jährlich wiederkehrende Darstellungen der Rekrutierungs- und Krankheitszahlen des Österreich-ungarischen Heeres von 1870 bis 1912 bieten. Bei näherer Betrachtung des Begriffs Statistik im 19. Jahrhundert zeigt sich, dass die heute gebräuchliche, mathematische Bedeutung damals noch nicht gegeben war. Was waren die Grundlagen und Datenquellen der Anwendung der Statistik in Administration und Medizin? In der damaligen Zeit stechen insbesondere die Infektionskrankheiten hervor. Es wurde ein neues Verständnis für die Übertragungswege und wirksamen Behandlungen gelegt. Wie entwickelte sich das zivile und militärische Sanitätswesen in der zweiten Hälfte des 19. Jahrhundert speziell in Österreich-Ungarn? Hinsichtlich der Inhalte der Jahrbücher stellen sich die Fragen: Welche Daten wurden dargestellt? Wie wurden die Daten zuverlässig erfasst und kumuliert? Das Material der Jahrbücher ist zu umfassend, um über den gesamten Zeitraum im Detail dargestellt zu werden. Daher werden die Anfangsjahre und Facetten ausgewählter Krankheiten und Aspekte herausgriffen: Erfassung der Infektionskrankheiten, Malaria, Tod, Selbstmorde und Selbstverstümmelungen, Geschlechtskrankheiten, hydrometrische Messungen und die Rolle der Frauen werden exemplarisch dargestellt. Die Beantwortung der Fragen erfolgt über die Rezeption der Ergebnisse in statistischen und ärztlichen Fachzeitschriften der damaligen Zeit. Dem werden zivile Entwicklungen in Österreich gegenübergestellt. Ebenso erfolgt eine Verortung der Aktivitäten Österreichs im europäischen Kontext. Eine weiterführende Forschung könnte das soziale Umfeld ins Auge fassen und die Gesundheit der gesellschaftlichen Gruppen Aristokratie, Bürgertum, Arbeiter, Bauern und die Bedingungen für deren Erkrankungen herausarbeiten.

description: A Lie system is a system of first-order ordinary differential equations describing the integral curves of a $t$-dependent vector field taking values in a finite-dimensional real Lie algebra of vector fields: a so-called Vessiot-Guldberg Lie algebra. We suggest the definition of a particular class of Lie systems, the $k$-symplectic Lie systems, admitting a Vessiot-Guldberg Lie algebra of Hamiltonian vector fields with respect to the presymplectic forms of a $k$-symplectic structure. We devise new $k$-symplectic geometric methods to study their superposition rules, time independent constants of motion and general properties. Our results are illustrated by examples of physical and mathematical interest. As a byproduct, we find a new interesting setting of application of the $k$-symplectic geometry: systems of first-order ordinary differential equations.

Survival probability of an edge Majorana in a 1-D p-wave superconducting chain under sudden quenching of parameters

description: We consider the temporal evolution of a zero energy edge Majorana of a spinless $p$-wave superconducting chain following a sudden change of a parameter of the Hamiltonian. Starting from one of the topological phases that has an edge Majorana, the system is suddenly driven to the other topological phase or to the (topologically) trivial phases and also to the quantum critical points (QCPs) separating these phases. The survival probability of the initial edge Majorana as a function of time is studied following the quench. Interestingly when the chain is quenched to the QCP, we find a nearly perfect oscillations of the survival probability, indicating that the Majorana travels back and forth between two ends, with a time period that scales with the system size. We also generalize to the situation when there is a next-nearest-neighbor hopping in superconducting chain and there resulting in a pair of edge Majorana at the each end of the chain in the topological phase. We show that the frequency of oscillation of the survival probability gets doubled in this case. We also perform an instantaneous quenching the Hamiltonian (with two Majorana modes at each end of the chain) to an another Hamiltonian which has only one Majorana mode in equilibrium; the MSP shows oscillations as a function of time with a noticeable decay in the amplitude. On the other hand for a quenching which is reverse to the previous one, the MSP decays rapidly and stays close to zero with fluctuations in amplitude.

description: Several studies show that the use of landmarks is crucial for pedestrian navigations systems. Furthermore, there are well-defined landmark features like its visual salience. However, the assessment and the selection of landmarks especially in large scale indoor environments is rarely examined. We conducted a user study in the university of Regensburg and assessed the visual attraction of objects with an eye tracker. Our finndings show that functional landmarks like doors and stairs are most likely to be looked at and named as a landmark. Moreover, we could prove that measuring visual salience only is not suffcient to identify landmarks with regard to the use in a pedestrian navigation system.
title: Gesundheitsbezogene Lebensqualität bei (Nicht-) Hundehalter*innen

description: In immer mehr Studien werden die Auswirkungen, die ein Hund auf seine*n Halter*in haben kann, diskutiert. Während einige Wissenschafter*innen behaupten, dass Hunde eine Verbesserung der Lebensqualität mit sich bringen, legen andere Studien keinen oder sogar einen negativen Effekt der Haustiere dar. Um diesem Widerspruch nachzugehen, wurde in der vor-liegenden Arbeit die Lebensqualität von Hundehalter*innen mit jener von Nicht-Hundehalter*innen verglichen. Anhand Fragen des WHOQOL-BREFs zur Erfassung von Lebensqualität sowie zusätzlich eigens erstellten hundespezifischen Fragen wurden im Zeit-raum Juni/Juli 2022 N=141 Personen sowohl online und an Universitäten, als auch an öffentlichen Plätzen rekrutiert und gebeten den Online-Fragebogen auf der Plattform SoSciSurvey auszufüllen. Die Ergebnisse verweisen auf eine signifikant bessere psychische Lebensqualität bei Hundehalter*innen, jedoch nur geringfügige Unterschiede in den Domänen physische, soziale, globale sowie umweltbezogene Lebensqualität. Nicht zuletzt scheinen auch Faktoren wie die Wohnsituation mit einer unmittelbar verfügbaren Grünfläche oder Balkon eine positive Auswirkung auf einzelne Bereiche der gesundheitsbezogenen Lebensqualität von Menschen zu haben.
description: Increasingly more studies are arguing about the effects a dog can have on its owner. While many scientists claim that dogs can cause an improvement in the quality of life, other studies show no or even negative effects of pets. In order to investigate this contradiction, the follow-ing work compared the quality of life of dog owners with the quality of life of non-dog own-ers. Based on the questionnaire WHO-QOL BREF for measuring quality of life as well as a self made questionnaire with dog-specific questions, N=141 people were recruited, partly online and partly at universities or in public places, to fill out the online questionnaire on the platform SoSciSurvey in June/July of 2022. The results indicate a significantly better psychological quality of life in dog owners, but only minor differences in the domains of physical, social, global and environmental quality of life. Last but not least, factors such as the housing situation with directly available green space or balcony also seem to have a positive effect on certain aspects of people’s health related quality of life.

description: Splines constitute an interesting way to flexibly estimate a nonlinear relationship between several covariates and a response variable using linear regression techniques. The popularity of splines is due to their easy application and hence the low computational costs since their basis functions can be added to the regression model like usual covariates. As long as no inequality constraints and penalties are imposed on the estimation, the degrees of freedom of the model estimation can be determined straightforwardly as the number of estimated parameters. This paper derives a formula for computing the hat matrix of a penalized and inequality constrained splines estimator. Its trace gives the degrees of freedom of the model estimation which are necessary for the calculation of several information criteria that can be used e.g. for specifying the parameters for the spline or for model selection.

subject: 810 Englische Literatur Amerikas

description: This article explores T.C. Boyle’s thirteenth novel When the Killing’s Done (2011) in regard to its representation of ecological crisis and the ensuing environmental activism. In particular, it argues that the distinctly urban background and way of life of the two main protagonists, National Park Service staff member Alma Boyd Takesue and radical eco-hipster Dave LaJoy, foster environmental imaginations of the California Channel Islands that underestimate the centuries-long agricultural uses of the islands and romanticize the islands’ ecosystems as pristine ‘wilderness.’ While this perception in the tradition of the ‘American cult of wilderness’ prompts Alma and the National Park Service to reestablish a historical state of the islands’ ecosystems through the calculated extermination of invasive species, eco-activist Dave fiercely fights for the right of every non-human animal to live. Ultimately, the novel deconstructs both these endeavors to biodiversity and animal rights as highly flawed and environmentally as well as ethically inconsistent.

description: Many machine learning models exist for battery management systems to utilize. Few have been shown to work. This work focuses on gathering data from cycling battery packs and sending this data directly to machine learning models built off robust datasets for applying the resulting predicted values and outputs directly on top of real-time systems. A parasitic sensor network was created composed of a main microcontroller, a host CPU, and various sensors including resistance temperature detection devices (RTDs), a voltage measurement circuit, current measurement circuit, and an accelerometer/gyroscope. The resulting network was integrated parasitically with a 4-cell 18650 SONY VTC6 battery pack, then tested both on-ground and in-flight with a commercial quadcopter. Real-time data for the battery pack with four cells in series was gathered. This real-time data stream was then integrated with data-driven neural network algorithms trained on various 18650 datasets and a real physical model to finalize the “AI BMS”. Using the power of non-linear models to infer battery health impacts not normally considered in battery management systems, the “AI BMS” was able to use low-fidelity real-time data in conjunction with a powerful multi-faceted model to make predictive decisions about battery health characteristics on top of normal system operations.

description: Presented on 15 February 2023 at the Research Software Engineering in Data and AI workshop hosted by The Alan Turing Institute and The University of Warwick (15-17 February 2023). The recording of this talk can be streamed on YouTube. Abstract Researchers often need to analyse sensitive data in order to answer important questions for health, government and society. Balancing the need to protect individual privacy and commercial confidentiality with the need to ensure that reliable insights can be made using sensitive data is challenging, and Trusted Research Environments (TREs) that provide secure analysis environments for working with sensitive data are a key part of striking this balance. The Alan Turing Institute has recently open-sourced its Data Safe Haven, a secure, scalable, reproducibly deployable, cloud-based TRE that we have been using for the last 4 years to support our researchers in working safely and productively with sensitive data. By openly publishing the code and documentation required to deploy, configure and manage a Data Safe Haven instance, we make it easier for others to deploy their own Trusted Research Environments, reducing the effort required to support their researchers in working safely with sensitive data. We've also been working closely with the wider community to better align work in this area, initially on the development of the information governance principals and design choices for our Data Safe Haven, which we published in 2019. More recently, we've been working closely with the DARE UK programme to define common requirements for Trusted Research Environments and have co-founded the RSE TRE Community, bringing together those who are developing and deploying TREs to more closely co-ordinate our work. In this talk we will give an overview of the Turing's Data Safe Haven and the information governance and design principals behind it, as well as the work we have been doing with the wider community to develop a common set of TRE requirements and to co-ordinate across organisations on the development, deployment and management of TREs.

description: Chiral topological insulator (AIII-class) with Landau levels is constructed based on the Nambu 3-algebraic geometry. We clarify the geometric origin of the chiral symmetry of the AIII-class topological insulator in the context of non-commutative geometry of 4D quantum Hall effect. The many-body groundstate wavefunction is explicitly derived as a $(l,l,l-1)$ Laughlin-Halperin type wavefunction with unique $K$-matrix structure. Fundamental excitation is identified with anyonic string-like object with fractional charge ${1}/({1+2(l-1)^2})$. The Hall effect of the chiral topological insulators turns out be a color version of Hall effect, which exhibits a dual property of the Hall and spin-Hall effects.

description: We develop ambitwistor string theories for 4 dimensions to obtain new formulae for tree-level gauge and gravity amplitudes with arbitrary amounts of supersymmetry. Ambitwistor space is the space of complex null geodesics in complexified Minkowski space, and in contrast to earlier ambitwistor strings, we use twistors rather than vectors to represent this space. Although superficially similar to the original twistor string theories of Witten, Berkovits and Skinner, these theories differ in the assignment of worldsheet spins of the fields, rely on both twistor and dual twistor representatives for the vertex operators, and use the ambitwistor procedure for calculating correlation functions. Our models are much more flexible, no longer requiring maximal supersymmetry, and the resulting formulae for amplitudes are simpler, having substantially reduced moduli. These are supported on the solutions to the scattering equations refined according to MHV degree and can be checked by comparison with corresponding formulae of Witten and of Cachazo and Skinner.

description: The energy spectrum of graphene sheet with a single barrier structure having a time periodic oscillating height and subjected to magnetic field is analyzed. The corresponding transmission is studied as function of the obtained energy and the potential parameters. Quantum interference within the oscillating barrier has an important effect on quasiparticles tunneling. In particular the time-periodic electromagnetic field generates additional sidebands at energies ε+ l\hbar ω(l=0,\pm 1, \cdots) in the transmission probability originating from the photon absorption or emission within the oscillating barrier. Due to numerical difficulties in truncating the resulting coupled channel equations we limited ourselves to low quantum channels, i.e. l=0,\pm 1.

title: Veränderung der Schüler*innenvorstellungen zur Evolutionstheorie im Verlauf der Sekundarstufe 1 und 2
Creators: name: Lindner, Magdalena
Year: 2023

description: Mit dem Ziel, die Veränderungen der Schüler*innenvorstellungen zur Evolution in der gesamten Sekundarstufe zu erheben, wurde eine quantitative Befragung durchgeführt. Hierfür wurde ein Fragebogen aus den von der Literatur zur Verfügung gestellten Items zusammengestellt. Die Ergebnisse zeigen einen fachlichen Wissenszuwachs mit steigender Schulstufe, jedoch nicht im befriedigenden Maße. Der gleichzeitig nur geringe Rückgang der anderen Alltagsvorstellungen zeigt, dass parallele Wissensstände seitens der Schüler*innen existieren. Außerdem deutet das festgestellte inkonsistente Antwortverhalten auf fehlende inhaltliche Verknüpfungen hin. Aus diesem Grund sind eine Überarbeitung und Weiterentwicklung des österreichischen Curriculums für die nahe Zukunft wünschenswert.

description: We perform a detail study of higher dimensional quantum Hall effects and A-class topological insulators with emphasis on their relations to non-commutative geometry. There are two different formulations of non-commutative geometry for higher dimensional fuzzy spheres; the ordinary commutator formulation and quantum Nambu bracket formulation. Corresponding to these formulations, we introduce two kinds of monopole gauge fields; non-abelian gauge field and antisymmetric tensor gauge field, which respectively realize the non-commutative geometry of fuzzy sphere in the lowest Landau level. We establish connection between the two types of monopole gauge fields through Chern-Simons term, and derive explicit form of tensor monopole gauge fields with higher string-like singularity. The connection between two types of monopole is applied to generalize the concept of flux attachment in quantum Hall effect to A-class topological insulator. We propose tensor type Chern-Simons theory as the effective field theory for membranes in A-class topological insulators. Membranes turn out to be fractionally charged objects and the phase entanglement mediated by tensor gauge field transforms the membrane statistics to be anyonic. The index theorem supports the dimensional hierarchy of A-class topological insulator. Analogies to D-brane physics of string theory are discussed too.

Nambu-Goldstone bosons and the Higgs mechanism without Lorentz invariance: Analysis based on constrained-system theory

description: First, we develop the counting rule for Nambu-Goldstone bosons to the system including two-time derivative terms. In this case, the type-II Nambu-Goldstone bosons may appear along with the massive Nambu-Goldstone ones. The number of the bosons is not reduced in contrast to the system without two-time derivative terms. We also investigate the reduction of the degrees of freedom from the perspective of the Dirac-Bergmann theory of constraints and reproduce the counting rule for Nambu-Goldstone bosons without Lorentz invariance. Then, we construct the generic Higgs model and study a Higgs phenomenon with these Nambu-Goldstone bosons on the basis of the Dirac-Bergmann theory. We show that the gauge fields in this system absorb all of the Nambu-Goldstone bosons such as the type-I, type-II and massive ones.

Nature of Roberge-Weiss transition end points for heavy quarks in $N_f=2$ lattice QCD with Wilson fermions

description: The phase structure of QCD with imaginary chemical potential provides information on the phase diagram of QCD with real chemical potential. With imaginary chemical potential $iμ_I=iπT$, previous studies show that the Roberge-Weiss (RW) transition end points are triple points at both large and small quark masses, and second order transition points at intermediate quark masses. The triple and second order end points are separated by two tricritical ones. We present simulations with $ N_f=2 $ Wilson fermions to investigate the nature of RW transition end points. The simulations are carried out at 8 values of the hopping parameter $κ$ ranging from 0.020 to 0.140 on different lattice volumes. The Binder cumulant, susceptibility and reweighted distribution of the imaginary part of Polyakov loop are employed to determine the nature of RW transition end points. The simulations show that the two tricritical points are within the range $0.070-0.080$ and $0.120-0.140$, respectively.

Alternating knots with unknotting number one
Creators: name: McCoy, Duncan
Publisher: name: arXiv
Year: 2013
Subjects: subject: Geometric Topology (math.GT)
subject: FOS: Mathematics

description: We prove that if an alternating knot has unknotting number one, then there exists an unknotting crossing in any alternating diagram. This is done by showing that the obstruction to unknotting number one developed by Greene in his work on alternating 3-braid knots is sufficient to identify all unknotting number one alternating knots. As a consequence, we also get a converse to the Montesinos trick: an alternating knot has unknotting number one if its branched double cover arises as half-integer surgery on a knot in $S^3$. We also reprove a characterisation of almost-alternating diagrams of the unknot originally due to Tsukamoto.
description: 38 pages, 15 figures. This a significant revision of the first version. A proof of Tsukamoto's work on almost-alternating diagrams of the unknot is now included. There is also an additional formulation of the main theorem which makes precise the signs of the unknotting crossings and the resulting half-integer surgeries. Some comments on potential further questions have also been added

EEG-to-fMRI Neuroimaging Cross Modal Synthesis in Python

description: Electroencepholography (EEG) and functional magnetic resonance imaging (fMRI) are two ways of recording brain activity; the former provides good time resolution but poor spatial resolution, while the converse is true for the latter. Recently, deep neural network models have been developed that can synthesize fMRI activity from EEG signals, and vice versa. Because these generative models simulate data, they make it easier for neuroscientists to test ideas about how EEG and fMRI signals relate to each other, and what both signals tell us about how the brain controls behavior. To make it easier for researchers to access these models, and to standardize how they are used, we developed a Python package, EEG-to-fMRI, which provides cross modal neuroimaging synthesis functionalities. This is the first open source software enabling neuroimaging synthesis. Our main focus is for this package to help neuroscience, machine learning, and health care communities. This study gives an in-depth description of this package, along with the theoretical foundations and respective results.

description: We present the first ab initio construction of valence-space Hamiltonians for medium-mass nuclei based on chiral two- and three-nucleon interactions using the in-medium similarity renormalization group. When applied to the oxygen isotopes, we find experimental ground-state energies are well reproduced, including the flat trend beyond the drip line at 24O. Similarly, natural-parity spectra in 21,22,23,24O are in agreement with experiment, and we present predictions for excited states in 25,26O. The results exhibit a weak dependence on the harmonic-oscillator basis parameter and reproduce spectroscopy within the standard sd valence space.
