description: Disordered lattice spin systems are crucial in both theoretical and applied physics. However, understanding their properties poses significant challenges for Monte Carlo simulations. In this work, we investigate the two-dimensional random-bond Ising model using the recently proposed Tensor Network Monte Carlo (TNMC) method. This method generates biased samples from conditional probabilities computed via tensor network contractions and corrects the bias using the Metropolis scheme. Consequently, the proposals provided by tensor networks function as block updates for Monte Carlo simulations. Through extensive numerical experiments, we demonstrate that TNMC simulations can be performed on lattices as large as $1024\times 1024$ spins with moderate computational resources, a substantial increase from the previous maximum size of $64\times 64$ in MCMC. Notably, we observe an almost complete absence of critical slowing down, enabling the efficient collection of unbiased samples and averaging over a large number of random realizations of bond disorders. We successfully pinpoint the multi-critical point along the Nishimori line with significant precision and accurately determined the bulk and surface critical exponents. Our findings suggest that TNMC is a highly efficient algorithm for exploring disordered and frustrated systems in two dimensions.

description: Despite impressive advancements of industrial collaborative robots, their potential remains largely untapped due to the difficulty in balancing human safety and comfort with fast production constraints. To help address this challenge, we present PRO-MIND, a novel human-in-the-loop framework that leverages valuable data about the human co-worker to optimise robot trajectories. By estimating human attention and mental effort, our method dynamically adjusts safety zones and enables on-the-fly alterations of the robot path to enhance human comfort and optimal stopping conditions. Moreover, we formulate a multi-objective optimisation to adapt the robot's trajectory execution time and smoothness based on the current human psycho-physical stress, estimated from heart rate variability and frantic movements. These adaptations exploit the properties of B-spline curves to preserve continuity and smoothness, which are crucial factors in improving motion predictability and comfort. Evaluation in two realistic case studies showcases the framework's ability to restrain the operators' workload and stress and to ensure their safety while enhancing human-robot productivity. Further strengths of PRO-MIND include its adaptability to each individual's specific needs and sensitivity to variations in attention, mental effort, and stress during task execution.

description: This paper provides a new admissibility criterion for choosing physically relevant weak solutions of the equations of Lagrangian and continuum mechanics when non-uniqueness of solutions to the initial value problem occurs. The criterion is motivated by the classical least action principle but is now applied to initial value problems which exhibit non-unique solutions. Examples are provided to Lagrangian mechanics and the Euler equations of barotropic fluid mechanics. In particular, we show the least action admissibility principle prefers the classical two shock solution to the Riemann initial value problem to certain solutions generated by convex integration. On the other hand, Dafermos's entropy criterion prefers convex integration solutions to the two shock solutions. Furthermore, when the pressure is given by $p(ρ)=ρ^2$, we show that the two shock solution is always preferred whenever the convex integration solutions are defined for the same initial data.

description: Der gegenwärtige Konsolidierungsprozess in Afghanistan soll neben staatlichen Strukturen und einer freien Marktwirtschaft auch eine Zivilgesellschaft aufbauen, sowie eine funktionierende Demokratie schaffen. Nach dem Regime Change soll also ein Nation-Building stattfinden. Der Versuch der Internationalen Gemeinschaft den Krieg mittels Intervention zu beenden, hat jedoch geradewegs in dessen weitere Eskalation gemündet. Das Forschungsinteresse der Diplomarbeit liegt in der Herausarbeitung jener Faktoren, die einer friedvollen Konstituierung des politischen Systems entgegen stehen. Der Schwerpunkt der Arbeit liegt beim Demokratisierungsprozess, da die staatliche Ebene alleine nie einigende Wirkung erzielte. In Afghanistan war der Staat zu keiner Zeit als oberstes Organisationsprinzip anerkannt. Es haben sich keine staatlichen und nationalen Strukturen im Sinne der Staatstrias Staatsvolk, Staatsgebiet und Staatsgewalt herausgebildet. Seit 1978 erodiert das bislang wenig Vorhandene aufgrund des Kriegs und des damit verbundenen wirtschaftlichen Verfalls. In der Diplomarbeit konnte gezeigt werden, dass sich die bereits in der afghanischen Geschichte als konfliktverschärfend ausgemachten Momente nicht geändert haben. Vielmehr stärkt das neue zentralistische politische System genau jene Akteure und Strukturen, die durch die Intervention und den anschließenden Konstituierungsprozess eliminiert werden hätten sollen. Ein föderales System könnte die in Afghanistan vorherrschenden Partikularinteressen friedlicher kanalisieren.

description: [Introduction] Everyone wants to live a good life. But how exactly should we define "well-being," the concept of living a good life? Traditionally, philosophy offers us three competing accounts (e.g. Kagan, 1998; Daly, 2017). First, there’s hedonism, which defines well-being in terms of an individual’s experienced happiness. Second, there’s desire satisfaction theory, which maintains that well-being is related to the extent to which your desires, actual or ideal, end up being fulfilled. And, finally, there is objective list theory, which contends that well-being depends on the extent to which your life possesses objectively good qualities, which might, for example, include things like friendship, achievement, autonomy, knowledge, and happiness.

description: Implementing Deep Neural Networks (DNNs) on resource-constrained edge devices is a challenging task that requires tailored hardware accelerator architectures and a clear understanding of their performance characteristics when executing the intended AI workload. To facilitate this, we present an automated generation approach for fast performance models to accurately estimate the latency of a DNN mapped onto systematically modeled and concisely described accelerator architectures. Using our accelerator architecture description method, we modeled representative DNN accelerators such as Gemmini, UltraTrail, Plasticine-derived, and a parameterizable systolic array. Together with DNN mappings for those modeled architectures, we perform a combined DNN/hardware dependency graph analysis, which enables us, in the best case, to evaluate only 154 loop kernel iterations to estimate the performance for 4.19 billion instructions achieving a significant speedup. We outperform regression and analytical models in terms of mean absolute percentage error (MAPE) compared to simulation results, while being several magnitudes faster than an RTL simulation.

description: Racial and ethnic disparities in COVID-19 risk are well-documented; however, few studies in older adults have examined multiple factors related to COVID-19 exposure, concerns, and behaviors or conducted race- and ethnicity- stratified analyses. The Women’s Health Initiative (WHI) provides a unique opportunity to address those gaps.We conducted a secondary analysis of WHI data from a supplemental survey of 48,492 older adults (mean age 84 years). In multivariable-adjusted modified Poisson regression analyses, we examined predisposing factors and COVID-19 exposure risk, concerns, and behaviors. We hypothesized that women from minoritized racial or ethnic groups, compared to Non-Hispanic White women, would be more likely to report: exposure to COVID-19, a family or friend dying from COVID-19, difficulty getting routine medical care or deciding to forego care to avoid COVID-19 exposure, and having concerns about the COVID-19 pandemic.Asian women and Non-Hispanic Black/African American women had a higher risk of being somewhat/very concerned about risk of getting COVID 19 compared to Non-Hispanic White women and each were significantly more likely than Non-Hispanic White women to report forgoing medical care to avoid COVID-19 exposure. However, Asian women were 35% less likely than Non-Hispanic White women to report difficulty getting routine medical care since March 2020 (aRR 0.65; 95% CI 0.57, 0.75).We documented COVID-related racial and ethnic disparities in COVID-19 exposure risk, concerns, and care-related behaviors that disfavored minoritized racial and ethnic groups, particularly Non-Hispanic Black/African American women.

description: In the present work we explore nonclassical effects in the phase space of two superposed kitten states induced by photon addition and subtraction operations applied in different sequences. We investigate two scenarios: In the first, photon addition is applied to the state, followed by photon subtraction, while in the second, the order of operations is reversed. We demonstrate that applying multiphoton operations to the state results in notable nearly isotropic sub-Planck structures, with the characteristics of these structures being influenced by the photon addition and subtraction. Increasing the number of added photons compresses the sub-Planck structures in both cases. Photon subtraction, however, has the opposite effect on the sub-Planck structures in the first case and no effect in the second. Furthermore, we observe that the optimal choices of multiphoton operations lead to improved isotropy of sub-Planck structures in our cases. The presence of the sub-Planck structures in our states leads to improved sensitivity to displacements, exceeding the standard quantum limit, as verified across all the depicted scenarios.

SOIL-BIODEGRADABLE MULCH IN A DOUBLE CROPPED STRAWBERRY AND LETTUCE SYSTEM AND IMPLICATIONS ON SPLASH DISPERSAL OF BOTRYTIS CINEREA
Creators: name: Wang, Xuechun
Publisher: name: Washington State University
Year: 2023

description: Plastic mulch can promote yield of strawberry (Fragaraia × ananassa Duch.) and lettuce (Lactuca sativa L.) with soil-biodegradable mulch (BDM) providing opportunities to reduce plastic waste generation. However, BDM is a relatively new technology with limited studies in double-cropped systems. Mulch impacts on fungal pathogens dispersed through rain splash is also unknown. The objective of the first experiment was to compare nondegradable plastic mulches [polyethylene (PE) film and “weedmat”, a woven PE-mulch] and BDM to bare ground cultivation in a strawberry-lettuce double cropped system in maritime Pacific Northwest (PNW). A split-plot randomized complete block design experiment was conducted from May 2020 through Sept. 2021 with mulch treatment as the main factor and double cropping rotation scheme as the split-plot factor. BDM performed similarly to PE in terms of soil temperature and moisture modification, weed suppression, and promotion of crop growth and yield despite high levels of deterioration. Crop performance was reduced in the bare ground treatment due to the absence of soil temperature and moisture enhancements as well as weed suppression effects provided by mulching. The objective of the second experiment was to assess the potential impact BDM has on splash dispersal of asexual spores (conidia) of Botrytis cinerea, which causes gray mold disease in strawberry. Splash dispersal pattern of BDM were compared to PE and weedmat using a fabricated rain simulator in a screenhouse. Mulch permeability, surface characteristics, and splash dynamics were also characterized. Splashed conidia on weedmat was unpredictable and less consistent due to the woven, physical structure and semi-permeable characteristics. Total conidia counts were greater for BDM than PE and splash dynamics data confirmed this. In conclusion, double cropping with BDM is a promising practice for diversified production systems but could contribute to greater incidence of gray mold and other fungal diseases dependent on rain dispersal due to enhanced splash dispersal.

description: Excerpts from the report: The volume of U.S. agricultural exports has been trending upward since 1950. U.S. agricultural exports in 1965 represented 23 percent of the value of all U.S. exports. Wheat accounted for more than a sixth of the value of agricultural exports from the United States in 1965; while corn and soybeans jointly accounted for nearly a fourth. Together, these 3 products made up more than two-fifths of the total value of U.S. agricultural exports and nearly a tenth of the value of all U.S. exports in this period. More than two-fifths of the volume of all wheat and more than half of all corn moving in world trade during 1963-65 originated in the United States. The long-term outlook for voyage charter rates is favorable to U.S. exporters. Although European, Asian, and possibly African demand for U.S. farm products probably will increase, foreign flag rates may fall. Causing this fall will be an influx of shipping tonnage now under construction in foreign shipyards. While it is very unlikely that much grain will move in the newly constructed vessels, their entry into the market is likely to increase the total supply of shipping sufficiently to bring about downward pressure on ocean freight rates for grain.

description: In wideband systems operating at mmWave frequencies, intelligent reflecting surfaces (IRSs) equipped with many passive elements can compensate for channel propagation losses. Then, a phenomenon known as the beam-split (B-SP) occurs in which the phase shifters at the IRS elements fail to beamform at a desired user equipment (UE) over the total allotted bandwidth (BW). Although B-SP is usually seen as an impairment, in this paper, we take an optimistic view and exploit the B-SP effect to enhance the system performance via an orthogonal frequency division multiple access (OFDMA). We argue that due to the B-SP, when an IRS is tuned to beamform at a particular angle on one frequency, it also forms beams in different directions on other frequencies. Then, by opportunistically scheduling different UEs on different subcarriers (SCs), we show that, almost surely, the optimal array gain that scales quadratically in the number of IRS elements can be achieved on all SCs in the system. We derive the achievable throughput of the proposed scheme and deduce that the system also enjoys additional multi-user diversity benefits on top of the optimal beamforming gain over the full BW. Finally, we verify our findings via numerical simulations.

description: We study the production of hypothetical vector particles, dark photons $γ^\prime$, with masses in the range 0.4--1.8 GeV via inelastic proton bremsstrahlung. We further develop the approach of arXiv:2409.11089 and refs. [2-3], where for the first time we considered the contributions to the cross section that are associated with the Pauli form factor in $ppγ^\prime$ vertex and obtained new splitting functions. We demonstrate numerically the importance of these corrections to full inelastic proton bremsstrahlung cross section and refine the sensitivity of the ongoing and future fixed-target experiments T2K, DUNE and SHiP to the parameters of dark photon model. A dedicated experiment on measurements of the proton electromagnetic form factors in the time-like region below the proton-antiproton threshold, like those suggested in PANDA at FAIR, would help to obtain the robust predictions for the dark photon production by a proton beam at fixed target.

description: This article examines management and coworker reactions to employee anger expressions that violate salient emotion display norms, for example, deviant anger, and explores whether these reactions can promote subsequent positive change at work. Full-time US employees volunteered information about workplace anger expressions they personally witnessed and felt ‘went too far’. Using open-ended survey questions, we identified three categories of deviant anger (physical acts, intense verbal displays, and inappropriate communication), as well as various formal and informal sanctioning and supportive responses initiated by organizational observers. Additional data collection and generalized linear modeling analysis revealed that when coworkers and management responded supportively to the angry employee (rather than with sanctions or doing nothing), favorable change occurred, improving the problematic situation. Implications for future research, management practices, and employee socialization are discussed.

description: Die vorliegende Studie versucht, das WiSK Klassenprojekt (Wiener soziales Kompetenztraining) durch die Anwesenheit eines ausgebildeten Therapiehundes zu modifizieren und die Wirksamkeit dieses Trainings zu überprüfen. Dafür werden die Grundprinzipien des etablierten WiSK Programms mit den positiven Wirkungen der tiergestützten Intervention kombiniert. Die Untersuchungsziele sind mittels Versuchgruppen-Kontroll-Design mit Messwiederholung überprüft worden. Die Stichprobe hat sich aus 76 Schülerinnen und Schülern der Sekundarstufe I im Alter von 10 bis 14 Jahren zusammengesetzt. Drei Interventionsgruppen haben am WiSK Klassenprojekt teilgenommen - eine Gruppe ist von einer Psychologin mit Therapiehund (N=20) betreut worden, eine von Psychologinnen (N=20) und eine von Lehrerinnen und Lehrern (N=20). Die Kontrollgruppe (N= 16) hat an keinem Training teilgenommen. Die summative Evaluation zeigt, dass die Kombination beider Interventionsformen (WiSK-Klassenprojekt und tiergestützte Interventionen) zu einer Verbesserung des sozial kompetenten Verhaltens (z.B. Steigerung der Empathie) und zum Teil zu einer Reduktion aggressiver Verhaltensweisen (Reduktion aggressiver Handlungen) beiträgt. Darüber hinaus kommt es zu einer Steigerung des Wohlbefindens der Schülerinnen und Schüler und zu einer Verbesserung des Klassenklimas. Die Wirksamkeit des Trainings kann jedoch nicht nur auf die Anwesenheit bzw. die Aktivitäten mit dem Therapiehund zurückgeführt werden, vielmehr zeigt sich ein klarer Teameffekt durch das Therapiebegleithunde-Team.
description: This study tries to enhance the Viennese Social Competence Training (ViSC) by working with a trained therapy-dog and evaluate the effectiveness of the training. Therefore, it combines basic principles of the ViSC and of animal-assisted interventions. The aims were reviewed by an intervention and control group design with pre- and post- test. The sample consists of 76 students aged between 10 and 14. Three classes participated in the program, one accompanied by a psychologist and a therapy-dog (N=20), one by psychologists (N=20) and one by teachers (N=20). The control group did not participate (N= 16) in a training program. The summative evaluation shows an increase of social competence (for example the increase of empathy and responsibility) and a reduction of aggressive behaviour by combining both interventions (ViSC classproject and animal-assisted interventions). Furthermore, children’s well-being increased and class climate improved. Results shown were based on a team effect (therapy dog and his trainer) and not only on the presence of the dog.

description: We study the implications of relaxing the requirement for ultralight axions to account for all dark matter in the Universe by examining mixed dark matter (MDM) cosmologies with axion fractions $f \leq 0.3$ within the fuzzy dark matter (FDM) window $10^{-25}$ eV $\lesssim m \lesssim 10^{-23}$ eV. Our simulations, using a new MDM gravity solver implemented in AxiREPO, capture wave dynamics across various scales with high accuracy down to redshifts $z\approx 1$. We identify halos with Rockstar using the CDM component and find good agreement of inferred halo mass functions (HMFs) and concentration-mass relations with theoretical models across redshifts $z=1-10$. This justifies our halo finder approach a posteriori as well as the assumptions underlying the MDM halo model AxionHMcode. Using the inferred axion halo mass-cold halo mass relation $M_{\text{a}}(M_{\text{c}})$ and calibrating a generalised smoothing parameter $α$ to our MDM simulations, we present a new version of AxionHMcode. The code exhibits excellent agreement with simulations on scales $k< 20 \ h$ cMpc$^{-1}$ at redshifts $z=1-3.5$ for $f\leq 0.1$ around the fiducial axion mass $m = 10^{-24.5}$ eV $ = 3.16\times 10^{-25}$ eV, with maximum deviations remaining below 10%. For axion fractions $f\leq 0.3$, the model maintains accuracy with deviations under 20% at redshifts $z\approx 1$ and scales $k< 10 \ h$ cMpc$^{-1}$, though deviations can reach up to 30% for higher redshifts when $f=0.3$. Reducing the run-time for a single evaluation of AxionHMcode to below $1$ minute, these results highlight the potential of AxionHMcode to provide a robust framework for parameter sampling across MDM cosmologies in Bayesian constraint and forecast analyses.

description: A team of multiple robots seamlessly and safely working in human-filled public environments requires adaptive task allocation and socially-aware navigation that account for dynamic human behavior. Current approaches struggle with highly dynamic pedestrian movement and the need for flexible task allocation. We propose Hyper-SAMARL, a hypergraph-based system for multi-robot task allocation and socially-aware navigation, leveraging multi-agent reinforcement learning (MARL). Hyper-SAMARL models the environmental dynamics between robots, humans, and points of interest (POIs) using a hypergraph, enabling adaptive task assignment and socially-compliant navigation through a hypergraph diffusion mechanism. Our framework, trained with MARL, effectively captures interactions between robots and humans, adapting tasks based on real-time changes in human activity. Experimental results demonstrate that Hyper-SAMARL outperforms baseline models in terms of social navigation, task completion efficiency, and adaptability in various simulated scenarios.

description: A memory consistency model specifies the allowed behaviors of shared memory concurrent programs. At the language level, these models are known to have a non-trivial impact on the safety of program optimizations, limiting the ability to rearrange/refactor code without introducing new behaviors. Existing programming language memory models try to address this by permitting more (relaxed/weak) concurrent behaviors but are still unable to allow all the desired optimizations. A core problem is that weaker consistency models may also render optimizations unsafe, a conclusion that goes against the intuition of them allowing more behaviors. This exposes an open problem of the compositional interaction between memory consistency semantics and optimizations: which parts of the semantics correspond to allowing/disallowing which set of optimizations is unclear. In this work, we establish a formal foundation suitable enough to understand this compositional nature, decomposing optimizations into a finite set of elementary effects on program execution traces, over which aspects of safety can be assessed. We use this decomposition to identify a desirable compositional property (complete) that would guarantee the safety of optimizations from one memory model to another. We showcase its practicality by proving such a property between Sequential Consistency (SC) and $SC_{RR}$, the latter allowing independent read-read reordering over $SC$. Our work potentially paves way to a new design methodology of programming-language memory models, one that places emphasis on the optimizations desired to be performed.
title: Die Bedeutung einer beruflichen Umschulungsmaßnahme im Lebenslauf von Frauen mit Behinderungen im Erwachsenenalter
Creators: name: Watzke, Anna Maria

description: Die vorliegende Forschungsarbeit geht der Frage nach, welche Bedeutung eine berufliche Umschulungsmaßnahme im Lebenslauf von Frauen mit Behinderung im Erwachsenenalter hat. Aufgrund des Eintritts einer Krankheit oder eines Unfalls, ist es den Frauen nicht möglich, ihren erlernten Erstberuf oder ihre berufliche Tätigkeit weiter auszuüben. Zur Beantwortung der Forschungsfrage wurden sechs Interviews mit Frauen geführt, welche an einer beruflichen Umschulungsmaßnahme im Beruflichen Bildungs- und Rehabilitationszentrum (BBRZ) Wien teilnehmen, um dort eine Ausbildung mit Lehrabschluss zu absolvieren. Um die berufliche Lebensgeschichte der Frauen erfassen zu können, wurden die Interviews in Anlehnung an das narrative Interview nach Schütze (1983) geführt. Die Auswertung erfolgte anhand einer Themenanalyse nach Froschauer/Lueger 2003. Es wurde eruiert, welche berufliche Lebensgeschichte die Frauen vorweisen und welche Gründe bestehen, dass sie an der Maßnahme teilnehmen. Im Weiteren wurde eruiert, ob die Umschulungsmaßnahme eine neue Chance in ihrem Leben darstellt, ob sie mit der Maßnahme zufrieden sind, welche Erwartungen sie nach Absolvierung der Maßnahme haben und wie sich ihr Lebenslauf seit dem Besuch der Maßnahme verändert hat. Die Forschungsarbeit zeigt auf, dass sich die Teilnahme an einer Umschulungsmaßnahme im Lebenslauf der Frauen als sehr bedeutsam erweist.

description: This thesis explores what is made possible by bringing Deleuze and Guattari’s assemblage theory into conversation with policy mobilities and Pacific research for the study of education development policy. Empirically, the research focuses on a particular policy assemblage, referred to in the thesis as Pacific regional education development policy (PREDP). The research takes as an entry point the becomings of the Pacific Regional Education Framework 2018-2030 (PacREF), and explores the flows, forces and intensities that produce regional institutional and intergovernmental cooperation on education policy and service delivery across the so-called developing island nations of the Pacific Ocean. The research explores what different ways of thinking about and engaging with PREDP are possible if we ask not what PREDP is nor how effective is it, but instead why PREDP has become in the way that it has, how is it sustained through encounters with the potential to destabilise it, and what capacities does it make possible. The research data has been generated from conversations with 30 policy actors and the analysis of relevant policy documents. By attending to the mutual presupposition of molar and molecular tendencies generated through PREDP, and embracing the both/and thinking of Pacific research, the research demonstrates how PREDP functions to make competing desires consistent. The research argues that PREDP can be experienced as both regional and national, local and global, an artefact of donor imposition and of decolonial resistance. The research re-problematises what are arguably staid dialectics of power/resistance, global/local, dependence/independence and generality/context. It reconceptualises these in terms of becomings of responsibility, interdependence and responsiveness. In so doing, the research makes significant contributions to Comparative and International Education and Critical Policy Studies literature, offering different ways of thinking-doing education policy research that might open-up new lines of flight for educational futures.

description: Excerpts from the report Highlights: Accounting data and operational information relative to 1964-65 were collected from 133 public cotton storage facilities. These participating plants were selected randomly to represent principal areas and types of facility. The sample included 73 interior or port compresses and 60 warehouses. The total capacity of sample plants was about 30 percent of that of all plants approved for storing cotton loaned or owned by the Commodity Credit Corporation (CCC). Two types of costs were developed for each of the principal services performed by each participating plant: (1) Average total cost which includes the expenditures of firms on an accrual basis, plus standardized allowances for depreciation and interest on capital based on original acquisition cost; and (2) average out-of-pocket cost which excludes allowances for depreciation and interest on investment. Also shown for each area are estimates of (1) long-run competitive rates, based on the total replacement cost including depreciation and interest on capital for marginal firms operating at 85 percent of capacity; and (2) short-run competitive rates, based on the out-of-pocket cost of marginal firms

description: We compute the two-loop four-point MHV form factor of the stress-tensor supermultiplet in planar ${\cal N}=4$ super Yang-Mills (SYM). This form factor is analogous to the Higgs plus four-gluon amplitudes in the heavy-top limit of QCD when translated to the ${\cal N}=4$ SYM context. We obtain the full $D$-dimensional integrands up to two loops via unitarity-cut methods. Subsequently, we utilize IBP reduction to express the result in terms of a set of uniformly transcendental basis integrals, incorporating the two-loop non-planar five-point one-mass integrals recently given by Abreu et al. [PRL 132 (2024) 14]. We obtain the two-loop finite remainder in the functional form in terms of the pentagon functions. The symbol of our remainder confirms the bootstrap results reported by Dixon et al. [PRL 130 (2023) 11]. We perform various non-trivial checks of our results, including the triple-collinear limit, which recovers the two-loop six-gluon remainder. We also show that the form factor has a directional dual conformal symmetry at the integrand level. Our results are expected to shed further light on the study of antipodal dualities and the computation of Higgs plus four-parton amplitudes in QCD.

title: Regeneration der Skelettmuskulatur durch Stammzellen
Creators: name: Hopfgartner, Barbara
Year: 2010

description: Die Magisterarbeit konzentriert sich auf die Grundlagenbiologie von Stamm- und Vorläuferzellen, speziell in der Skelettmuskulatur. Der Skelettmuskel ist reich an Muskelstammzellen und Vorläuferzellen, den Satellitenzellen, welche unter der Basallamina der Muskelfasern lokalisiert sind. Satellitenzellen werden vor allem bei einer Schädigung des Skelettmuskels aktiviert. In weiterer Folge proliferieren und differenzieren sie in neue Muskelfasern. Somit liegen die Hauptaufgaben der Satellitenzellen im postnatalen Muskelwachstum, Reparatur und Aufrechterhaltung von Skelettmuskulatur. Aufgrund des enormen Potentials der Satellitenzellen in der Regeneration von Skelettmuskulatur, ist das Interesse an der Stamm- und Vorläuferzellen vermittelten Regeneration in der Sportmedizin in den letzten Jahren stark gestiegen. Neue Methoden werden angewendet um den Einfluss von körperlicher Belastung auf die Stamm- und Vorläuferzellen vermittelte muskuloskeletale Regeneration zu untersuchen. Es sind genügend Studien vorhanden, die besagen, dass vor allem Krafttraining, aber auch Ausdauertraining, einen Einfluss auf den Satellitenpool haben. Gezielte körperliche Belastung beeinflusst die Aktivierung, Proliferation und Differenzierung der Satellitenzellen. Dies sind wichtige Mechanismen für die Muskeladaptation, welche Reparatur, Regeneration und Hypertrophie beinhaltet. Über die letzten Jahre kam es zu einem Anstieg an Sportverletzungen. Sportverletzungen betreffen für gewöhnlicher Weise Gewebe, die einer limitierenden Heilungsfähigkeit unterliegen. In den letzten Jahren kam es zu einer Verbesserung der Behandlungen von Sportverletzungen, jedoch gibt es bis heute noch keine optimale Strategien für die Behandlung von Sportverletzungen betreffend der Muskel, der Bänder und der Sehnen. Neue molekulare Zugänge fokussieren sich auf die Behandlung solcher Verletzungen. Diese Techniken gehören dem Tissue engineering an. Die Behandlung mit Wachstumsfaktoren stimulieren und beschleunigen den Heilungsprozess. Zelltherapie und Gentherapie sind ebenfalls vielversprechend.

description: Perovskite oxides hetero-structures are host to a large number of interesting phenomena such as ferroelectricity and 2D-superconductivity. Ferroelectric perovskite oxides have been of significant interest due to their possible use in MOSFETs and FRAM. SrHfO$_3$ (SHO) is a perovskite oxide with pseudo-cubic lattice parameter of 4.1 $\mathring{A}$ that previous DFT calculations suggest can be stabilized in a ferroelectric P4mm phase, similar to STO, when stabilized with sufficient compressive strain. Additionally, it is insulating, possesses a large band gap, and a high dielectric constant, making it an ideal candidate for oxide electronic devices. In this work, SHO films were grown by hybrid molecular beam epitaxy with a tetrakis(ethylmethylamino)hafnium(IV) source on GdScO$_3$ and TbScO$_3$ substrates. Equilibrium and strained SHO phases were characterized using X-ray diffraction, X-ray absorption spectroscopy, and scanning transmission electron microscopy to determine the perovskite phase of the strained films, with the results compared to density functional theory models of phase stability versus strain. Contrary to past reports, we find that compressively-strained SrHfO$_3$ undergoes octahedral tilt distortions and most likely takes on the I4/mcm phase with the a$^0$a$^0$c$^-$ tilt pattern.

description: Navigating in human-filled public spaces is a critical challenge for deploying autonomous robots in real-world environments. This paper introduces NaviDIFF, a novel Hamiltonian-constrained socially-aware navigation framework designed to address the complexities of human-robot interaction and socially-aware path planning. NaviDIFF integrates a port-Hamiltonian framework to model dynamic physical interactions and a diffusion model to manage uncertainty in human-robot cooperation. The framework leverages a spatial-temporal transformer to capture social and temporal dependencies, enabling more accurate spatial-temporal environmental dynamics understanding and port-Hamiltonian physical interactive process construction. Additionally, reinforcement learning from human feedback is employed to fine-tune robot policies, ensuring adaptation to human preferences and social norms. Extensive experiments demonstrate that NaviDIFF outperforms state-of-the-art methods in social navigation tasks, offering improved stability, efficiency, and adaptability.

Quantitative Polymerase Chain Reaction (qPCR) is a molecular method commonly used to detect and quantify bacterial DNA on food but is limited by its inability to distinguish between live and dead cell DNA. To overcome this obstacle, propidium monoazide (PMA) alone or with deoxycholate (DC) was used to prevent dead cell detection in qPCR. qPCR methods were used to detect strains of Escherichia coli O157, which can cause infection in humans with an infectious dose of less than 10 cells. A 5 strain E. coli O157:H7 cocktail was inoculated onto beef steaks and treated with interventions used in meat facilities (lactic acid (5%), peroxyacetic acid (200 ppm) or hot water (80 °C for 10 s)). Treatment of PMA or PMA + DC was applied to samples followed by DNA extraction and quantification in qPCR. RNA was also quantified in addition to conventional plating. For lactic acid intervention, qPCR DNA quantification of E. coli O157:H7 yielded 6.59 ± 0.21 and 6.30 ± 0.11 log gene copy #/cm 2 for control and lactic acid samples, respectively and after treatment with PMA or PMA + DC this was further reduced to 6.31 ± 0.21 and 5.58 ± 0.38, respectively. This trend was also observed for peroxyacetic acid and hot water interventions. In comparison, RNA quantification yielded 7.65 ± 0.13 and 7.02 ± 0.38 log reverse transcript/cm 2 for rRNA control and lactic acid samples, respectively, and for plating (LB), 7.51 ± 0.06 and 6.86 ± 0.32 log CFU/cm 2 , respectively. Our research determined that treatment of PMA + DC in conjunction with qPCR prevented dead cell DNA detection. However, it also killed cells injured from intervention that may have otherwise recovered. RNA quantification was more laborious and results had higher variability. Overall, quantification with conventional plating proved to be the most robust and reliable method for live EHEC detection on beef.
