Exact Charge-Conserving Scatter-Gather Algorithm for Particle-in-Cell Simulations on Unstructured Grids: A Geometric Perspective

description: We describe a charge-conserving scatter-gather algorithm for particle-in-cell simulations on unstructured grids. Charge conservation is obtained from first principles, i.e., without the need for any post-processing or correction steps. This algorithm recovers, at a fundamental level, the scatter-gather algorithms presented recently by Campos-Pinto et al. [1] (to first-order) and by Squire et al. [2], but it is derived here in a streamlined fashion from a geometric viewpoint. Some ingredients reflecting this viewpoint are (1) the use of (discrete) differential forms of various degrees to represent fields, currents, and charged particles and provide localization rules for the degrees of freedom thereof on the various grid elements (nodes, edges, facets), (2) use of Whitney forms as basic interpolants from discrete differential forms to continuum space, and (3) use of a Galerkin formula for the discrete Hodge star operators (i.e., "mass matrices" incorporating the metric datum of the grid) applicable to generally irregular, unstructured grids. The expressions obtained for the scatter charges and scatter currents are very concise and do not involve numerical quadrature rules. Appropriate fractional areas within each grid element are identified that represent scatter charges and scatter currents within the element, and a simple geometric representation for the (exact) charge conservation mechanism is obtained by such identification. The field update is based on the coupled first-order Maxwell's curl equations to avoid spurious modes with secular growth (otherwise present in formulations that discretize the second-order wave equation). Examples are provided to verify preservation of discrete Gauss' law for all times.

Search for patterns by combining cosmic-ray energy and arrival directions at the Pierre Auger Observatory

Publisher: name: arXiv
Year: 2014
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with $E \geq 6 \cdot 10^{19}$ eV by analyzing cosmic rays with energies above $E = 5 \cdot 10^{18}$ eV arriving within an angular separation of approximately $15°$. We characterize the energy distributions inside these regions by two independent methods, one searching for angular dependence of energy-energy correlations and one searching for collimation of energy along the local system of principal axes of the energy distribution. No significant patterns are found with this analysis. The comparison of these measurements with astrophysical scenarios can therefore be used to obtain constraints on related model parameters such as strength of cosmic-ray deflection and density of point sources.

description: A Teichmüller curve is an algebraic and isometric immersion of an algebraic curve into the moduli space of Riemann surfaces. We give the first explicit algebraic models of Teichmüller curves of positive genus. Our methods are based on the study of certain Hilbert modular forms and the use of Ahlfors's variational formula to identify eigenforms for real multiplication on genus two Jacobians. We also present evidence that Teichmüller curves admit a rich arithmetic geometry by exhibiting examples with small primes of bad reduction and notable divisors supported at their cusps.

description: The aim of this article is to establish the notion of bundle-type quasitoric manifolds and provide two classification results on them: (1) ($\mathbb{C}P^2\sharp\mathbb{C}P^2$)-bundle type quasitoric manifolds are weakly equivariantly homeomorphic if their cohomology rings are isomorphic, and (2) quasitoric manifolds over $I^3$ are homeomorphic if their cohomology rings are isomorphic. In the latter case, there are only four quasitoric manifolds up to weakly equivariant homeomorphism which are not bundle-type.

description: Unknown nonlinear dynamics often limit the tracking performance of feedforward control. The aim of this paper is to develop a feedforward control framework that can compensate these unknown nonlinear dynamics using universal function approximators. The feedforward controller is parametrized as a parallel combination of a physics-based model and a neural network, where both share the same linear autoregressive (AR) dynamics. This parametrization allows for efficient output-error optimization through Sanathanan-Koerner (SK) iterations. Within each SK-iteration, the output of the neural network is penalized in the subspace of the physics-based model through orthogonal projection-based regularization, such that the neural network captures only the unmodelled dynamics, resulting in interpretable models.

However, inspired by an attention to diverse forms of relationality in various traditions in the social sciences and humanities, including (but not limited) to process philosophy, this presentation explores the more varied potential of processing in open access publishing. Its particular focus is OA books, examining the way in which the soon to be launched Open Book Collective is an OA infrastructure that puts relations into play that extend far beyond the often increasingly tenuous relations that can connect a scholar to their academic products.

description: We consider simple stochastic climate models, described by slowly time-dependent Langevin equations. We show that when the noise intensity is not too large, these systems can spend substantial amounts of time in metastable equilibrium, instead of adiabatically following the stationary distribution of the frozen system. This behaviour can be characterized by describing the location of typical paths, and bounding the probability of atypical paths. We illustrate this approach by giving a quantitative description of phenomena associated with bistability, for three famous examples of simple climate models: Stochastic resonance in an energy balance model describing Ice Ages, hysteresis in a box model for the Atlantic thermohaline circulation, and bifurcation delay in the case of the Lorenz model for Rayleigh-Bénard convection.

We describe a group invariant, the involution graph, and we characterize the involution graphs of right-angled Coxeter groups. We use this characterization to describe a process for constructing candidate right-angled Coxeter presentations for a given group or proving that one cannot exist. We provide some first applications. In addition, we provide an elementary proof of rigidity of the defining graph for a right-angled Coxeter group. We also recover a result stating that if the defining graph contains no SILs, then Aut^0(W) is a right-angled Coxeter group.

We determine the full region of $(p,q)$ to admit global existence of small solutions, at least for spatial dimensions $n=2, 3$. Moreover, for many $(p,q)$ when there is no global existence, we obtain sharp lower bound of the lifespan, which is of the same order as the upper bound of the lifespan.

Stability analysis of chaotic systems from data

description: The prediction of the temporal dynamics of chaotic systems is challenging because infinitesimal perturbations grow exponentially. The analysis of the dynamics of infinitesimal perturbations is the subject of stability analysis. In stability analysis, we linearize the equations of the dynamical system around a reference point, and compute the properties of the tangent space (i.e., the Jacobian). The main goal of this paper is to propose a method that learns the Jacobian, thus, the stability properties, from observables (data). First, we propose the Echo State Network (ESN) with the Recycle Validation as a tool to accurately infer the chaotic dynamics from data. Second, we mathematically derive the Jacobian of the Echo State Network, which provides the evolution of infinitesimal perturbations. Third, we analyse the stability properties of the Jacobian inferred from the ESN, and compare them with the benchmark results obtained by linearizing the equations. The ESN correctly infers the nonlinear solution, and its tangent space with negligible numerical errors. In detail, (i) the long-term statistics of the chaotic state; (ii) the covariant Lyapunov vectors; (ii) the Lyapunov spectrum; (iii) the finite-time Lyapunov exponents; (iv) and the angles between the stable, neutral, and unstable splittings of the tangent space (the degree of hyperbolicity of the attractor). This work opens up new opportunities for the computation of stability properties of nonlinear systems from data, instead of equations.

description: The recent global re-emergence of Xylella fastidiosa (Xf) has been associated to infections on several new host species and in particular to severe infections on olive trees, reported both in Europe and southern America. Although, initial report of Xf infections on olives, caused by strains of the subsp. multiplex, from California were associated to erratic appearance of olive leaf scorching or branch desiccation, severe phenomena of decline and extensive desiccations have been repeatedly reported associated to strains of the subspecies pauca in Italy, Brazil and Argentina. Furthermore, biological and molecular studies on olives belonging to different cultivars and infected with isolates of the subsp. pauca identified cultivars with differential susceptibility and traits of resistance. In this work, we used the strain CO33 taxonomically related to subsp. sandyi, to infect olive plants of the cultivar Cellina di Nardò and Leccino, previously characterized as susceptible and resistant, respectively. Twelve months after inoculation, Xf CO33 induced twig desiccations limitedly to the inoculated plants of the cv Cellina di Nardò. Indeed, the symptomless plants of the cv Leccino harbored lower bacterial populations than cv Cellina di Nardò. Transcriptome profiling of the xylem tissues showed that Xf is sensed by plants of both cultivars with high numbers of differentially expressed genes. Among transcripts showing the highest up regulation in cv Leccino are Leucine Rich Receptor like kinases, already identified in the transcriptomes of trees infected with Xf subsp. pauca. Conversely, tissues from symptomatic plants of Cellina di Nardò display a typical defense reaction with pathogenesis related proteins among major up regulated genes. Besides extending the data on the susceptibility of olives to Xf strains of a different subspecies, the data confirm the resistance of the cv Leccino to this pathogen, supporting evidence that different mechanisms of host-pathogen interactions exist in susceptible and resistant olive cultivars.
Majorana bound states from exceptional points in non-topological superconductors

description: Recent experimental efforts towards the detection of Majorana bound states have focused on creating the conditions for topological superconductivity. Here we demonstrate an alternative route, which achieves fully localised zero-energy Majorana bound states when a topologically trivial superconductor is strongly coupled to a helical normal region. Such a junction can be experimentally realised by e.g. proximitizing a finite section of a nanowire with spin-orbit coupling, and combining electrostatic depletion and a Zeeman field to drive the non-proximitized (normal) portion into a helical phase. Majorana zero modes emerge in such an open system without fine-tuning as a result of charge-conjugation symmetry, and can be ultimately linked to the existence of `exceptional points' (EPs) in parameter space, where two quasibound Andreev levels bifurcate into two quasibound Majorana zero modes. After the EP, one of the latter becomes non-decaying as the junction approaches perfect Andreev reflection, thus resulting in a Majorana dark state (MDS) localised at the NS junction. We show that MDSs exhibit the full range of properties associated to conventional closed-system Majorana bound states (zero-energy, self-conjugation, $4π$-Josephson effect and non-Abelian braiding statistics), while not requiring topological superconductivity.

title: Entwicklung eines Prototyps für die bodengebundene Temperaturmessung an der Mesopause mit einem Räumlich-Heterodynen Interferometer

description: This thesis deals with the development of a new generation of GRound based Infrared P-branch Spectrometers (GRIPS). Those devices are commonly used for the observation of mesopause temperatures by evaluating the nightly emissions of the OH-layer in about 87 km altitude. Yet, due to fundamental limitations of widely used grating spectrometers regarding optical throughput and spectral resolution, a prototype based on the technique of so called Spatial Heterodyne Interferometers (SHI) was developed, built and tested. The experimental verification included tests using a specialized light source and field measurements of actual atmospheric emissions. The experimental results show good accordance with prior simulations. Spectral resolution and fringe frequencies agreed well with the design values. Furthermore, the atmospheric measurements show statistical uncertainties at least comparable to present instruments, although the visibility of the interference fringes was impaired by a misalignment of the SHI that was only detected after the field tests. It is argued that a rebuild of the SHI can raise the efficiency by at least one order of magnitude. An actual rebuild and a full characterization of the improved prototype had to be rescheduled due to the COVID-19 pandemic and could not be included into this thesis.

description: Event-based image representations are fundamentally different to traditional dense images. This poses a challenge to apply current state-of-the-art models for object detection as they are designed for dense images. In this work we evaluate the YOLO object detection model on event data. To this end we replace dense-convolution layers by either sparse convolutions or asynchronous sparse convolutions which enables direct processing of event-based images and compare the performance and runtime to feeding event-histograms into dense-convolutions. Here, hyper-parameters are shared across all variants to isolate the effect sparse-representation has on detection performance. At this, we show that current sparse-convolution implementations cannot translate their theoretical lower computation requirements into an improved runtime.
A lazy approach to on-line bipartite matching

description: We present a new approach, called a lazy matching, to the problem of on-line matching on bipartite graphs. Imagine that one side of a graph is given and the vertices of the other side are arriving on-line. Originally, incoming vertex is either irrevocably matched to an another element or stays forever unmatched. A lazy algorithm is allowed to match a new vertex to a group of elements (possibly empty) and afterwords, forced against next vertices, may give up parts of the group. The restriction is that all the time each element is in at most one group. We present an optimal lazy algorithm (deterministic) and prove that its competitive ratio equals $1-π/\cosh(\frac{\sqrt{3}}{2}π)\approx 0.588$. The lazy approach allows us to break the barrier of $1/2$, which is the best competitive ratio that can be guaranteed by any deterministic algorithm in the classical on-line matching.

description: Abstract: The study aims to ascertain the prevalence and distribution of non-communicable diseases (NCDs) among Nigerian public service employees, the use of the National Health Insurance Scheme (NHIS) by those with NCDs, the factors that influence NHIS use, and the satisfaction of NCD patients with NHIS services. 350 civil officials from several ministries, departments, and parastatals in Abuja, Nigeria, were polled using a structured questionnaire to learn about their demographics, clinical information, NHIS service usage, and level of satisfaction. According to the study, 53.3% of individuals had NCDs, with hypertension being the most common (with 30.0%) of them. Only 16.0% of participants utilized NHIS services, with NHIS utilization being significantly higher among those aged ≤ 25 years and single individuals. Satisfaction with NHIS services was poor, with the lowest rating for the reliability of the health insurance scheme's service delivery in providing promised services (2.25 out of 5). The findings suggest a need for strategies to improve NHIS utilization and service delivery, especially among individuals with NCDs.

description: Weakly bound molecules have physical properties without atomic analogues, even as the bond length approaches dissociation. In particular, the internal symmetries of homonuclear diatomic molecules result in formation of two-body superradiant and subradiant excited states. While superradiance has been demonstrated in a variety of systems, subradiance is more elusive due to the inherently weak interaction with the environment. Here we characterize the properties of deeply subradiant molecular states with intrinsic quality factors exceeding $10^{13}$ via precise optical spectroscopy with the longest molecule-light coherent interaction times to date. We find that two competing effects limit the lifetimes of the subradiant molecules, with different asymptotic behaviors. The first is radiative decay via weak magnetic-dipole and electric-quadrupole interactions. We prove that its rate increases quadratically with the bond length, confirming quantum mechanical predictions. The second is nonradiative decay through weak gyroscopic predissociation, with a rate proportional to the vibrational mode spacing and sensitive to short-range physics. This work bridges the gap between atomic and molecular metrology based on lattice-clock techniques, yielding new understanding of long-range interatomic interactions and placing ultracold molecules at the forefront of precision measurements.

description: The Hubbard model is an important tool to understand the electrical properties of various materials. More specifically, on the honeycomb lattice it is used to describe graphene predicting a quantum phase transition from a semimetal to a Mott insulating state. In this work two different numerical techniques are presented that have been employed for simulations of the Hubbard model: The Hybrid Monte Carlo algorithm on the one hand allowed us to simulate unprecedentedly large lattices, whereas Tensor Networks can be used to completely avoid the sign problem. Respective strengths and weaknesses of the methods are discussed.

On the stability of thin-shell wormholes

description: A thin-shell wormhole is theoretically constructible by surgically grafting together two Schwarzschild spacetimes using the so-called cut-and-paste technique. By describing such a wormhole as the limiting case of a spherical shell, it is shown that the structure must be unstable to linearized radial perturbations. Some earlier studies by the author et al. have shown, however, that under certain conditions, thin-shell wormholes can be stable.

Photon splitting corrections to soft-photon resummation

description: In this paper we present an algorithm to add photon-splitting corrections to the Yennie-Frautschi-Suura-style soft-photon resummation available in the Sherpa Monte-Carlo event generator. Photon-splitting corrections enter at NNLO in QED and, as these effects are not incorporated in the standard QED FSR resummations, their size is larger than the pure hard photon-emission corrections at the same order. We introduce different lepton dressing strategies which incorporate further leptons and hadrons in addition to the customary photons, and discuss their sensitivity to dressing parameters such as the cone size. Finally, we quantify the effects of photon splittings into charged fermions and scalars under different such dressing strategies on $Z\to e^+e^-$ decays and find effects of up to 1% for suitably inclusive dressing strategies independent of the dressing cone size, and up to 9% if only photons are used in the dressing procedure with large dressing cones.

description: This is a revision of the online November 2021 Brighton thrombosis with thrombocytopenia syndrome (TTS) case definition and a new Brighton Collaboration case definition for vaccine-induced immune thrombocytopenia and thrombosis (VITT). These case definitions are intended for use in clinical trials and post-licensure pharmacovigilance activities to facilitate safety data comparability across multiple settings. They are not intended to guide clinical management.

The case definitions were developed by a group of subject matter and Brighton Collaboration process experts as part of the Coalition for Epidemic Preparedness Innovations (CEPI)-funded Safety Platform for Evaluation of vACcines (SPEAC).

The case definitions, each with defined levels of diagnostic certainty, are based on relevant published evidence and expert consensus and are accompanied by specific guidelines for TTS and VITT data collection and analysis. The document underwent peer review by a reference group of vaccine safety stakeholders and haematology experts to ensure case definition useability, applicability and scientific integrity.

description: Anthracnose leaf spot and ripe rot disease, caused by Colletotrichum gloeosporioides in India, is of economic importance. The objective of the investigation was to isolate and characterise bacterial antagonists from the grape berry surface. Nine bacteria out of the 46 that were isolated significantly inhibited C. gloeosporioides in a dual culture assay. Six of these nine microorganisms demonstrated pathogen inhibition by producing extracellular volatile and non-volatile compounds. Bacteria SB5, SB13, and SB15 were chosen for the polyhouse experiment because they demonstrated the best disease control in a detached leaf assay. At 1 × 106 CFU/ml of bacterial concentration, both curative and preventive trials showed significant disease inhibition. Based on morphological and molecular characterisation the bacteria were identified as Bacillus species. All three strains could be effectively used for the biological control of C. gloeosporioides.
