description: In this article a new high order accurate cell-centered Arbitrary-Lagrangian-Eulerian (ALE) Godunov-type finite volume method with time-accurate local time stepping (LTS) is presented. The method is by construction locally and globally conservative. The scheme is based on a one-step predictor-corrector methodology in space-time and uses three main building blocks: First, a high order piecewise polynomial WENO reconstruction, to obtain a high order data representation in space from the known cell averages of the underlying finite volume scheme. Second, a high order space-time Galerkin predictor step based on a weak formulation of the governing PDE on moving control volumes. Third, a high order one-step finite volume scheme, based directly on the integral formulation of the conservation law in space-time. The algorithm being entirely based on space-time control volumes naturally allows for hanging nodes also in time, hence in this framework the implementation of a consistent and conservative time-accurate LTS becomes very natural and simple. The method is validated on some classical shock tube problems for the Euler equations of compressible gasdynamics and the magnetohydrodynamics equations (MHD). The performance of the new scheme is compared with a classical high order ALE finite volume scheme based on global time stepping. To the knowledge of the author, this is the first high order accurate Lagrangian finite volume method ever presented together with a conservative and time-accurate local time stepping feature.

description: We experimentally investigate shear thickening in dense granular suspensions under oscillatory shear. Directly imaging the suspension-air interface, we observe dilation beyond a critical strain $γ_c$ and the end of shear thickening as the maximum confining stress is reached and the contact line moves. Analyzing the shear profile, we extract the viscosity contributions due to hydrodynamics $η_μ$, dilation $η_c$ and sedimentation $η_g$. While $η_g$ governs the shear thinning regime, $η_μ$ and $η_c$ together determine the shear thickening behavior. As the suspending liquid's viscosity varies from 10 to 1000 cst, $η_μ$ is found to compete with $η_c$ and soften the discontinuous nature of shear thickening.

description: In this paper, we provide an intuitive viewing to simplify the Siamese-based trackers by converting the tracking task to a classification. Under this viewing, we perform an in-depth analysis for them through visual simulations and real tracking examples, and find that the failure cases in some challenging situations can be regarded as the issue of missing decisive samples in offline training. Since the samples in the initial (first) frame contain rich sequence-specific information, we can regard them as the decisive samples to represent the whole sequence. To quickly adapt the base model to new scenes, a compact latent network is presented via fully using these decisive samples. Specifically, we present a statistics-based compact latent feature for fast adjustment by efficiently extracting the sequence-specific information. Furthermore, a new diverse sample mining strategy is designed for training to further improve the discrimination ability of the proposed compact latent network. Finally, a conditional updating strategy is proposed to efficiently update the basic models to handle scene variation during the tracking phase. To evaluate the generalization ability and effectiveness and of our method, we apply it to adjust three classical Siamese-based trackers, namely SiamRPN++, SiamFC, and SiamBAN. Extensive experimental results on six recent datasets demonstrate that all three adjusted trackers obtain the superior performance in terms of the accuracy, while having high running speed.

description: Phosphine is a dangerous gas commonly used in fumigations throughout the world. Grain that has not fully released the phosphine it absorbed during fumigation may continue to desorb phosphine into the headspace of a storage structure. U.S. OSHA standards for handling phosphine state the acceptable limit at 0.3 ppm. If this limit is exceeded grain handling may become dangerous. It is important to understand the process of phosphine venting and desorption in order to ensure safe handling of fumigated grain in silos and during shipments. In order to achieve this, the venting and release of phosphine was studied on location in a well-sealed grain silo in Lake Grace, Western Australia, to serve as a set of data for verification of a computational model. This situation was then modeled using a 3D finite element model and compared to the real world results. Results were calculated using two fumigant desorption models based on previous literature, a reversed sorption model and an air-grain equilibrium model. Simulations reproduced accurate trends of desorption but did not accurately reproduce the quantity of fumigant, with a 55.5% error for the model based on reversed sorption equations and 86.3% error for the air-grain equilibrium based model. For both models, simulations were conducted to compare the effectiveness of existing grain venting regulations at producing grain that is within safe handling limits. These results highlight the necessity for continued desorption research and the importance of following venting guidelines.

description: The discovery of a 126 GeV Higgs like scalar at the LHC along with the non observation of the supersymmetric particles, has in turn lead to constraining various supersymmetric models through the Higgs data. We here consider the case of both MSSM, as well its extension containing an additional chiral singlet superfield, NMSSM. We concentrate on the case where we identify the second lightest Higgs boson as the 126 GeV state discovered at the CERN LHC and consider the invisible decays of the low mass Higgs bosons in both MSSM and NMSSM. We find that in case of the MSSM with universal boundary conditions at the GUT scale, it is not possible to have light neutralinos leading to the decay channel $H\rightarrow \tildeχ_1^0 \tildeχ_1^0$. The invisible decay mode is allowed in case of certain $SO(10)$ and $E_6$ grand unified models with large representations and nonuniversal gaugino masses at the GUT scale. In case of the NMSSM, for the parameter space considered it is possible to have the invisible decay channel with universal gaugino masses at the GUT scale. We furthermore consider the most general case, with $M_1$ and $M_2$ as independent parameters for both MSSM and NMSSM. We isolate the regions in parameter space in both cases, where the second lightest Higgs boson has a mass of 126 GeV and then concentrate on the invisible decay of Higgs to lighter neutralinos. The other non-standard decay mode of the Higgs is also considered in detail. The invisible Higgs branching ratio being constrained by the LHC results, we find that in this case with the second lightest Higgs being the 126 GeV state, more data from the LHC is required to constrain the neutralino parameter space, compared to the case when the lightest Higgs boson is the 126 GeV state.

description: We show that the number of distinct topological states associated to a given knotted defect, $L$, in a nematic liquid crystal is equal to the determinant of the link $L$. We give an interpretation of these states, demonstrate how they may be identified in experiments and describe the consequences for material behaviour and interactions between multiple knots. We show that stable knots can be created in a bulk cholesteric and illustrate the topology by classifying a simulated Hopf link. In addition we give a topological heuristic for the resolution of strand crossings in defect coarsening processes which allows us to distinguish topological classes of a given link and to make predictions about defect crossings in nematic liquid crystals.

Towards the baseline of health research infrastructure: the development of the Self Research Network Netherlands (ZONN)
Creators: name: Remmers, Gaston
Publisher: name: Zenodo
Year: 2023

description: In the Netherlands, the health care system is thought to operate at different levels or lines of care. The first line of care is the general physician, the second one links to local and regional hospitals and paramedic services, the third one is embodied by the specialized academic hospitals and carecenters. Yet, increasingly, the 'zero' line of care is recognized, which is the citizen that takes care of his/her own health. Especially in the wake of healthy lifestyle management, the 'zero-line of care' is becoming more and more important.
In analogy of this, in this poster we present the 'zero line of health research'. We argue that the observational and experimental capacities of citizens constitute the baseline of health research. Their research efforts lead to functional solutions for the involved citizens and to hypothesis that entail health value for others but need further exploration. Internationally, these are known under labels such as Do-it-Yourself medicine (Wexler, 2022) or Personal Science (Wolf and Groot, 2020).
Yet, the baseline of health research is organized in a very fragmented way. There is hardly general accessible infrastructure available regarding methodology, ethics, funding, publications or data-infrastructure (Transitieteam GROZ, 2019). At the same time, this type of research tends to have little profile among either research or health professionals. Lots of potentially rich citizen science in the health domain hence remains unused. 
The poster outlines the birth of the 'Self Research Network Netherlands' (known in Dutch under the acronym of ZONN, from ZelfOnderzoek Netwerk Nederland, or ZONN). It details the learnings of different patients communities in encounters with the current health research regime, and their considerations to start building an infrastructure on their own terms. The first lines of action comprise a) an online course for patients/citizens on how to conduct self research (Personal Science); b) the identification, evaluation and development of 'workplaces for self research' and c) a dialogue model for patients and patientgroups to reflect on 'why would I /we engage in self research'.

description: Current induced domain wall (DW) motion has been investigated in a 600-nm wide nanowire using multilayer film with a structure of Ta(5 nm)/Pd(5 nm)/[CoFe(0.4 nm)/Pd(1.2 nm)]$_{15}$/Ta(5 nm)in terms of anomalous Hall effect measurements. It is found that motion of DWs can be driven by a current density as low as 1.44$\times$10$^{11}$ A.m$^{-2}$. The effect of the Oersted field ($H_{Oe}$) and spin transfer torque field ($H_{ST}$), which are considered as effective fields for DW motion, has been quantitatively separated from the dependence of depinning fields on the current. The results show that the motion of the walls was essentially dominated by the non-adiabaticity with a high non-adiabatic factor $β$ up to 0.4.

description: In this concept note, produced in the framework of BRIDGES' "Migration Narratives in Political Debate and Policy-making" (Work Package 7), we develop a conceptual and methodological framework for the analysis of how different narratives shape, and are deployed in, political debate and policymaking. In the first part, we set out the features and functions of narratives in public political debate and policy-making, highlighting the complex interplay between media and political narratives and narratives in more technocratic policy venues. Based on existing literature, we argue that narratives in different political and policy-making arenas are governed by different logics and, therefore, will engender different discursive styles ('lay/populist' versus 'technocratic'). In the second part, we analyse how political and policy actors respond to different narratives, setting out a four-way typology of government strategies for responding to (especially populist) narratives: embracing, adapting, rejecting, or ignoring (decoupling). Finally, in part three, we develop a unique method for empirically identifying these strategies.

description: Based on the solution of the stochastic Landau-Lifshitz-Gilbert equation discretized for a ferromagnetic chain subject to a uniform temperature gradient, we present a detailed numerical study of the spin dynamics with a focus particularly on finite-size effects. We calculate and analyze the net longitudinal spin current for various temperature gradients, chain lengths, and external static magnetic fields. In addition, we model an interface formed by a nonuniformly magnetized finite-size ferromagnetic insulator and a normal metal and inspect the effects of enhanced Gilbert damping on the formation of the space-dependent spin current within the chain. A particular aim of this study is the inspection of the spin Seebeck effect beyond the linear response regime. We find that within our model the microscopic mechanism of the spin Seebeck current is the magnon accumulation effect quantified in terms of the exchange spin torque. According to our results, this effect drives the spin Seebeck current even in the absence of a deviation between the magnon and phonon temperature profiles. Our theoretical findings are in line with the recently observed experimental results by M. Agrawal et al., Phys. Rev. Lett. 111, 107204 (2013).

description: We use topological summaries based on Betti curves to characterize the large-scale spatial distribution of simulated dark matter haloes and galaxies. Using the IllustrisTNG and CAMELS-SAM simulations, we show that the topology of the galaxy distribution is significantly different from the topology of the dark matter halo distribution. Further, there are significant differences between the distributions of star-forming and quiescent galaxies. These topological differences are broadly consistent across all simulations, while at the same time there are noticeable differences when comparing between different models. Finally, using the CAMELS-SAM simulations, we show that the topology of the quiescent galaxies in particular depends strongly on the amount of supernova feedback. These results suggest that topological summary statistics could be used to help better understand the processes of galaxy formation and evolution.

description: We report on deep observations of the extended TeV gamma-ray source MGRO J1908+06 made with the VERITAS very high energy (VHE) gamma-ray observatory. Previously, the TeV emission has been attributed to the pulsar wind nebula (PWN) of the Fermi-LAT pulsar PSR J1907+0602. We detect MGRO J1908+06 at a significance level of 14 standard deviations (14 sigma) and measure a photon index of 2.20 +/- 0.10_stat +/- 0.20_sys. The TeV emission is extended, covering the region near PSR J1907+0602 and also extending towards SNR G40.5--0.5. When fitted with a 2-dimensional Gaussian, the intrinsic extension has a standard deviation of sigma_src = 0.44 +/- 0.02 degrees. In contrast to other TeV PWNe of similar age in which the TeV spectrum softens with distance from the pulsar, the TeV spectrum measured near the pulsar location is consistent with that measured at a position near the rim of G40.5--0.5, 0.33 degrees away.

Temporal Variations And Spectral Properties of Be/X-ray Pulsar GRO J1008-57 Studied by INTEGRAL

description: Spin period variations and hard X-ray spectral properties of Be/X-ray pulsar GRO J1008-57 are studied with INTEGRAL observations. The pulsation periods at 93.66 s in 2004 and at 93.73 s in 2009 are determined. Pulse profiles of GRO J1008-57 during outbursts are energy dependent: double-peak profile in soft bands of 3-7 keV and single-peak profile in hard X-rays above 7 keV. GRO J1008-57 has undergone a spin-down trend from 1993-2009 with a rate of 4.1x10^-5 s day^-1, and might transfer into a spin-up trend after 2009. The spectra from 3-100 keV of GRO J1008-57 during outbursts are fitted with photon index of 1.4 and cutoff energies of 23-29 keV. We find a relatively soft spectrum in early phase of the 2009 outburst with cutoff energy 13 keV. Above a hard X-ray flux of 10^-9 erg cm^-2 s^-1, the spectra of GRO J1008-57 during outbursts need an enhanced hydrogen absorption of column density 6x10^22 cm^-2. The observed dip-like pulse profile of GRO J1008-57 in soft X-ray bands should be caused by this intrinsic absorption. Around the outburst peaks, a possible cyclotron resonance scattering feature at 74 keV is detected in the spectra of GRO J1008-57, making the source as the neutron star of highest magnetic field (6.6x10^12 G) in known accreting X-ray pulsars. Two modulations periods at 124.38 and 248.78 days are found using RXTE/ASM light curves of GRO J1008-57. Two flare peaks appearing in the folded light curve have different spectral properties. The normal outburst lasting 0.1 orbital phase has a hard spectrum and cannot be detected below 3 keV. The second flare lasting ten days shows a very soft spectrum without significant detections above 5 keV. Lack of soft X-ray emissions in outbursts should be caused by the enhanced hydrogen absorption near the periastron passage. Soft spectral origins in the second flares still need further detailed studies with soft X-ray spectroscopies.

description: Dwarf galaxies and globular clusters may contain intermediate mass black holes ($10^{3}$ to $10^{5}$ solar masses) in their cores. Estimates of ~$10^{3}$ neutron stars in the central parsec of the Galaxy and similar numbers in small elliptical galaxies and globular clusters along with an estimated high probability of ms-pulsar formation in those environments has led many workers to propose the use of ms-pulsar timing to measure the mass and spin of intermediate mass black holes. Models of pulsar motion around a rotating black hole generally assume geodesic motion of a "test" particle in the Kerr metric. These approaches account for well-known effects like de Sitter precession and the Lense-Thirring effect but they do not account for the non-linear effect of the pulsar's stress-energy tensor on the space-time metric. Here we model the motion of a pulsar near a black hole with the Mathisson-Papapetrou-Dixon (MPD) equations. Numerical integration of the MPD equations for black holes of mass 2 X $10^{6}$, $10^{5}$ and $10^{3}$ solar masses shows that the pulsar will not remain in an orbital plane with motion vertical to the plane being largest relative to the orbit's radial dimensions for the lower mass black holes. The pulsar's out of plane motion will lead to timing variations that are up to ~10 microseconds different from those predicted by planar orbit models. Such variations might be detectable in long term observations of millisecond pulsars. If pulsar signals are used to measure the mass and spin of intermediate mass black holes on the basis of dynamical models of the received pulsar signal then the out of plane motion of the pulsar should be part of that model.

Abstract:This lecture covers key aspects and trends in electric vehicle (EV) battery charging, focusing on requirements, state-of-the-art, and new developments in power electronics technologies. Starting from low-to-medium power EV chargers, two-stage conversion systems are common, including a Power Factor Corrector (PFC) rectifier followed by a DC-DC converter. These chargers can be integrated into vehicles (on-board) or located at EV charging stations (off-board), with galvanic isolation for safety. Fast DC chargers, primarily unidirectional (grid-to-vehicle), prioritize quick recharging times but need to consider grid capacity with the rise of high-power chargers near cities. Future charging infrastructures will cater to higher power demands, especially for heavy-duty electric vehicles, necessitating new investments. Innovations such as direct MV AC grid connections and the use of multilevel cascaded H-bridge circuits with medium frequency transformers will be crucial. Public battery chargers will benefit from multiport, flexible, and intelligent designs using multiplexing techniques to optimize power utilization. These systems should also incorporate energy storage to manage power demand, reduce costs, and participate in ancillary service markets, enhancing profitability. Wireless power EV chargers require further R&D for efficient circuit solutions, safety measures, and power quality management. Addressing these topics, such as foreign object detection and optimal transformer coil design, remains crucial for developing high-power wireless chargers and overcoming associated challenges.
Decomposition by Approximation with Pulse Waves Allowing Further Research on Sources of Voltage Fluctuations

description: Voltage fluctuations are common disturbances in power grids. Initially, it is necessary to selectively identify individual sources of voltage fluctuations to take actions to minimize the effects of voltage fluctuations. Selective identification of disturbing loads is possible by using a signal chain consisting of demodulation, decomposition, and assessment of the propagation of component signals. The accuracy of such an approach is closely related to the applied decomposition method. The paper presents a new method for decomposition by approximation with pulse waves. The proposed method allows for an correct identification of selected parameters, that is, the frequency of changes in the operating state of individual sources of voltage fluctuations and the amplitude of voltage changes caused by them. The article presents results from numerical simulation studies and laboratory experimental studies, based on which the estimation errors of the indicated parameters were determined by the proposed decomposition method and other empirical decomposition methods available in the literature. The real states that occur in power grids were recreated in the research. The metrological interpretation of the results obtained from the numerical simulation and experimental research is discussed.

Non-analytic behavior of the Casimir force across a Lifshitz transition in a spin-orbit coupled material

description: We propose the Casimir effect as a general method to observe Lifshitz transitions in electron systems. The concept is demonstrated with a planar spin-orbit coupled semiconductor in a magnetic field. We calculate the Casimir force between two such semiconductors and between the semiconductor and a metal as a function of the Zeeman splitting in the semiconductor. The Zeeman field causes a Fermi pocket in the semiconductor to form or collapse by tuning the system through a topological Lifshitz transition. We find that the Casimir force experiences a kink at the transition point and noticeably different behaviors on either side of the transition. The simplest experimental realization of the proposed effect would involve a metal-coated sphere suspended from a micro-cantilever above a thin layer of InSb (or another semiconductor with large $g$-factor). Numerical estimates are provided and indicate that the effect is well within experimental reach.

description: Cloud gaming services and remote play offer a wide range of advantages but can inherent a considerable delay between input and action also known as latency. Previous work indicates that deep learning algorithms such as artificial neural networks (ANN) are able to compensate for latency. As high latency in video games significantly reduces player performance and game experience, this work investigates if latency can be compensated using ANNs within a live first-person action game. We developed a 3D video game and coupled it with the prediction of an ANN. We trained our network on data of 24 participants who played the game in a first study. We evaluated our system in a second user study with 96 participants. To simulate latency in cloud game streaming services, we added 180 ms latency to the game by buffering user inputs. In the study we predicted latency values of 60 ms, 120 ms and 180 ms. Our results show that players achieve significantly higher scores, substantially more hits per shot and associate the game significantly stronger with a positive affect when supported by our ANN. This work illustrates that high latency systems, such as game streaming services, benefit from utilizing a predictive system.

description: We develop a first-principle generalised density of state method for studying numerically quantum field theories with a complex action. As a proof of concept, we show that with our approach we can solve numerically the strong sign problem of the $Z_3$ spin model at finite density. Our results are confirmed by standard simulations of the theory dual to the considered model, which is free from a sign problem. Our method opens new perspectives on ab initio simulations of cold dense quantum systems, and in particular of Yang-Mills theories with matter at finite densities, for which Monte Carlo based importance sampling are unable to produce sufficiently accurate results.
