description: Data-parallel particle advection algorithms contain multiple controls that affect their execution characteristics and performance, in particular how often to communicate and how much work to perform between communications. Unfortunately, the optimal settings for these controls vary based on workload, and, further, it is not easy to devise straight-forward heuristics that automate calculation of these settings. To solve this problem, we investigate a machine learning-based autotuning approach for optimizing data-parallel particle advection. During a pre-processing step, we train multiple machine learning techniques using a corpus of performance data that includes results across a variety of workloads and control settings. The best performing of these techniques is then used to form an oracle, i.e., a module that can determine good algorithm control settings for a given workload immediately before execution begins. To evaluate this approach, we assessed the ability of seven machine learning models to capture particle advection performance behavior and then ran experiments for 108 particle advection workloads on 64 GPUs of a supercomputer. Our findings show that our machine learning-based oracle achieves good speedups relative to the available gains.

Do electrons change their c-axis kinetic energy upon entering the superconducting state?

Publisher: name: arXiv

Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The interlayer tunneling mechanism of the cuprate high temperature superconductors involves a conversion of the confinement kinetic energy of the electrons perpendicular to the CuO-planes ($c$-axis) in the normal state to the pair binding energy in the superconducting state. This mechanism is discussed and the arguments are presented from the point of view of general principles. It is shown that recent measurements of the $c$-axis properties support the idea that the electrons substantially lower their $c$-axis kinetic energy upon entering the superconducting state, a change that is nearly impossible in any conventional mechanism. The proper use of a $c$-axis conductivity sum rule is shown to resolve puzzles involving the penetration depth and the optical measurements.

description: We study the family of piecewise linear differential systems in the plane with two pieces separated by a cubic curve. Our main result is that 7 is a lower bound for the Hilbert number of this family. In order to get our main result, we develop the Melnikov functions for a class of nonsmooth differential systems, which generalizes, up to order 2, some previous results in the literature. Whereas the first order Melnikov function for the nonsmooth case remains the same as for the smooth one (i.e. the first order averaged function) the second order Melnikov function for the nonsmooth case is different from the smooth one (i.e. the second order averaged function). We show that, in this case, a new term depending on the jump of discontinuity and on the geometry of the switching manifold is added to the second order averaged function.

description: In situ computation of Lagrangian flow maps to enable post hoc time-varying vector field analysis has recently become an active area of research. However, the current literature is largely limited to theoretical settings and lacks a solution to address scalability of the technique in distributed memory. To improve scalability, we propose and evaluate the benefits and limitations of a simple, yet novel, performance optimization. Our proposed optimization is a communication-free model resulting in local Lagrangian flow maps, requiring no message passing or synchronization between processes, intrinsically improving scalability, and thereby reducing overall execution time and alleviating the encumbrance placed on simulation codes from communication overheads. To evaluate our approach, we computed Lagrangian flow maps for four time-varying simulation vector fields and investigated how execution time and reconstruction accuracy are impacted by the number of GPUs per compute node, the total number of compute nodes, particles per rank, and storage intervals. Our study consisted of experiments computing Lagrangian flow maps with up to 67M particle trajectories over 500 cycles and used as many as 2048 GPUs across 512 compute nodes. In all, our study contributes an evaluation of a communication-free model as well as a scalability study of computing distributed Lagrangian flow maps at scale using in situ infrastructure on a modern supercomputer.

description: Data-parallel programming (DPP) has attracted considerable interest from the visualization community, fostering major software initiatives such as VTK-m. However, there has been relatively little recent investigation of data-parallel APIs in higherlevel languages such as Python, which could help developers sidestep the need for low-level application programming in C++ and CUDA. Moreover, machine learning frameworks exposing data-parallel primitives, such as PyTorch and TensorFlow, have exploded in popularity, making them attractive platforms for parallel visualization and data analysis. In this work, we benchmark data-parallel primitives in PyTorch, and investigate its application to GPU volume rendering using two distinct DPP formulations: a parallel scan and reduce over the entire volume, and repeated application of data-parallel operators to an array of rays. We find that most relevant DPP primitives exhibit performance similar to a native CUDA library. However, our volume rendering implementation reveals that PyTorch is limited in expressiveness when compared to other DPP APIs. Furthermore, while render times are sufficient for an early ''proof of concept'', memory usage acutely limits scalability.

description: Shape-morphing structures based on pressure actuation promise efficiency gains and performance improvements in aeronautics, but require complex three-dimensional geometries. The compliance of these morphing structures originates from local areas of reduced wall thickness. However, the required high wall thickness ratios are challenging for integral fabrication from high-performance fiber-reinforced plastics, which are demanded to achieve high load-bearing capacity. This study investigates different woven flexure hinges made from a hybrid yarn of glass fibers and the polyamide PA6 for application in pressure-actuated cellular structures. The flexure hinges are mechanically characterized under pure axial and pure bending loading in a tensile and a column bending test method specifically derived for flexure hinges. The specimen quality is further assessed by permeability testing, optical microscopy, and thermogravimetric analysis. This study shows that the stiffness of anisotropic flexure hinges can be determined in simple mechanical tests without the need for complex modeling of reinforcing fibers or consideration of manufacturing-specific effects. The mechanical properties of a double-layer hinge configuration are superior to those of a single-layer configuration, whereas integrating additively manufactured PA6 inlays into the woven preform offers an effective approach for achieving high wall thickness ratios. The most promising hinge configuration is selected for the integral fabrication of the aeronautical morphing structure, which consists of multiple pressurized cells.

description: We study the perturbative dynamics of an infinite gravitating Nambu-Goto string within the general-relativistic perturbation framework. We develop the gauge invariant metric perturbation on a spacetime containing a self-gravitating straight string with a finite thickness and solve the linearized Einstein equation. In the thin string case, we show that the string does not emit gravitational waves by its free oscillation in the first order with respect to its oscillation amplitude, nevertheless the string actually bends when the incidental gravitational waves go through it.

Linear combinations of these condensates correspond to the d- and g-wave pairings. Microwave electric field applied in the ab-plane induces Josephson transitions between the condensates. Dependence of the absorption upon direction, amplitude and frequency of the external microwave field is calculated. Results of the calculation are compared with the observed recently novel non-linear phenomena in microwave absorption of $YBaCu_2O_{7-δ}$ single crystals.

description: A reliable sense-and-avoid system is critical to enabling safe autonomous operation of unmanned aircraft. Existing sense-and-avoid methods often require specialized sensors that are too large or power intensive for use on small unmanned vehicles. This paper presents a method to estimate object distances based on visual image sequences, allowing for the use of low-cost, on-board monocular cameras as simple collision avoidance sensors. We present a deep recurrent convolutional neural network and training method to generate depth maps from video sequences. Our network is trained using simulated camera and depth data generated with Microsoft's AirSim simulator. Empirically, we show that our model achieves superior performance compared to models generated using prior methods.We further demonstrate that the method can be used for sense-and-avoid of obstacles in simulation.

description: As a fundamental and challenging problem in computer vision, hand pose estimation aims to estimate the hand joint locations from depth images. Typically, the problem is modeled as learning a mapping function from images to hand joint coordinates in a data-driven manner. In this paper, we propose Context-Aware Deep Spatio-Temporal Network (CADSTN), a novel method to jointly model the spatio-temporal properties for hand pose estimation. Our proposed network is able to learn the representations of the spatial information and the temporal structure from the image sequences. Moreover, by adopting adaptive fusion method, the model is capable of dynamically weighting different predictions to lay emphasis on sufficient context. Our method is examined on two common benchmarks, the experimental results demonstrate that our proposed approach achieves the best or the second-best performance with state-of-the-art methods and runs in 60fps.

description: The topological nature of the disorder of glasses and supercooled liquids strongly affects their high-frequency dynamics. In order to understand its main features, we analytically studied a simple topologically disordered model, where the particles oscillate around randomly distributed centers, interacting through a generic pair potential. We present results of a resummation of the perturbative expansion in the inverse particle density for the dynamic structure factor and density of states. This gives accurate results for the range of densities found in real systems.

description: Building on a significant amount of current research that examines the idea of platform-portable parallel code across different types of processor families, this work focuses on two sets of related questions. First, using a performance analysis methodology that leverages multiple metrics including hardware performance counters and elapsed time on both CPU and GPU platforms, we examine the performance differences that arise when using two common platform portable parallel programming approaches, namely OpenMP and VTK-m, for a stencil-based computation, which serves as a proxy for many different types of computations in visualization and analytics. Second, we explore the performance differences that result when using coarserand finer-grained parallelism approaches that are afforded by both OpenMP and VTK-m.

description: In this work, we present Unity Point-Cloud Interactive Core, a novel interactive point cloud rendering pipeline for the Unity Development Platform. The goal of the proposed pipeline is to expedite the development process for point cloud applications by encapsulating the rendering process as a standalone component, while maintaining flexibility through an implementable interface. The proposed pipeline allows for rendering arbitrarily large point clouds with improved performance and visual quality. First, a novel dynamic batching scheme is proposed to address the adaptive point sizing problem for level-of-detail (LOD) point cloud structures. Then, an approximate rendering algorithm is proposed to reduce overdraw by minimizing the overall number of fragment operations through an intermediate occlusion culling pass. For the purpose of analysis, the visual quality of renderings is quantified and measured by comparing against a high-quality baseline. In the experiments, the proposed pipeline maintains above 90 FPS for a 20 million point budget while achieving greater than 90% visual quality during interaction when rendering a point-cloud with more than 20 billion points.

The Coulomb gap in the I(V) curves can be expressed as a simple function of the capacitances in the series. Furthermore, the magnitude of the differential conductivity at current onset is calculated in terms of the model. The results are discussed with respect to the number of junctions.

description: In the current discussions on combining work and family life, the idea of shorter working hours for fathers is becoming ever more popular. Although the proportion of part-time working men has somewhat increased in the last few years, parttime employment has been largely studied for women and mothers. Much less is known about men’s, and particularly fathers’, part-time employment. This study seeks to fill this gap by analysing part-time work among fathers in Germany, Sweden, Ireland, and the Netherlands using data from the European Labour Force Survey (LFS) from the year 2014. We show that fathers’ lower earning capacity within couples is not associated with a higher probability of working part-time in any of the four countries. Irrespective of the occupational status differences within couples, fathers in Germany and Ireland with three or more children are more likely to work part-time than fathers with fewer children; moreover, in both countries, married fathers are less likely to work part-time than unmarried fathers. While fathers of small children in the Netherlands are more likely to work part-time if they have a lower occupational status than their female partners, these fathers are less likely to work part-time in Ireland. Zusammenfassung In der aktuellen Debatte um eine verbesserte Vereinbarkeit von Familie und Beruf geht es zunehmend auch um kürzere Arbeitszeiten von Vätern. Trotz eines leichten Anstiegs teilzeitarbeitender Männer in den letzten Jahren hat sich die sozialwissenschaftliche Forschung bislang vornehmlich mit Teilzeitarbeit von Frauen beschäftigt. Erkenntnisse darüber, unter welchen Bedingungen Männer, insbesondere Väter, Teilzeit arbeiten, gibt es kaum. Unsere Studie will zur Schließung dieser Forschungslücke mittels einer Analyse von Individualdaten der Europäischen Arbeitskräfteerhebung (EU AKE) für Deutschland, Schweden, Irland und die Niederlande aus dem Jahr 2014 beitragen. Wir können zeigen, dass Väter, die gleiche oder geringere Verdienstmöglichkeiten als ihre Partnerinnen haben, in keinem der Länder mit einer höheren Wahrscheinlichkeit Teilzeit arbeiten als Väter mit höheren Verdienstmöglichkeiten. Ungeachtet beruflicher Statusunterschiede innerhalb der Paarbeziehung arbeiten Väter mit drei oder mehr Kindern in Deutschland und Irland eher in Teilzeit; außerdem arbeiten verheiratete Väter in beiden Ländern seltener in Teilzeit als unverheiratete. Während in den Niederlanden Väter mit geringeren Verdienstmöglichkeiten als ihre Partnerinnen häufiger in Teilzeit arbeiten, wenn ein kleines Kind zu versorgen ist, arbeiten diese Väter in Irland seltener in Teilzeit.

description: The so-called \textit{China crisis}, well documented in \textit{History of the IAU} by Adriaan Blaauw and in \textit{Under the Same Starry Sky: History of the IAU} by Chengqi Fu and Shuhua Ye, refers to the withdrawal in 1960 of the People's Republic of China (PRC) from the Union. The crisis stemmed from the admission by the IAU, amidst strong protest from PRC and some other member countries, of the Republic of China (ROC) to the Union, creating the so-called `\textit{Two Chinas}' -- or `\textit{One China, one Taiwan}' problem. The crisis directly led to the absence of mainland Chinese astronomers from the stage of international collaborations and exchanges, and was only solved two decades later. The solution, accepted by all the parties involved, is that China is to have two adhering organizations, with mainland China astronomers represented by the Chinese Astronomical Society located in Nanjing (China Nanjing) and China Taiwan astronomers represented by the Academia Sinica located in Taipei (China Taipei). The denominations `\textit{China Nanjing}' and `\textit{China Taipei}' represent the IAU official resolution and should be used in all IAU events. The China crisis, probably the most serious one in IAU history, was a painful lesson in the 100-year development of the Union. Yet, with its eventual solution, the Union has emerged stronger, upholding its spirit of promoting astronomical development through international collaboration of astronomers from all regions and countries, regardless of the political systems, religion, ethnicity, gender or level of astronomical development.

description: We have proposed and demonstrated a fast and robust method of population transfer between two quantum states using a quadratically chirped laser source. Incorporating the Jaynes-Cummings in a full quantum description of the interaction, and numerically solving the time-dependent Schrödinger equation, transition probabilities have been obtained and the condition of the adiabatic passage is investigated. In this scheme, a laser source has been swept quadratically in time for arbitrarily engineering the transition probabilities. The results show that complete and robust population transfer could be selectively achieved by appropriate adjusting of the laser chirping parameter, the center frequency and the coupling strength which the time of the complete transition could be drastically decreased compared to linearly traditional chirped laser. Furthermore, another feature of using the quadratically chirped laser is the stimulation of intermediate transitions under the nonadiabatic passage.

description: We present numerical hydrodynamical evolutions of rapidly rotating relativistic stars, using an axisymmetric, nonlinear relativistic hydrodynamics code. We use four different high-resolution shock-capturing (HRSC) finite-difference schemes (based on approximate Riemann solvers) and compare their accuracy in preserving uniformly rotating stationary initial configurations in long-term evolutions. Among these four schemes, we find that the third-order PPM scheme is superior in maintaining the initial rotation law in long-term evolutions, especially near the surface of the star. It is further shown that HRSC schemes are suitable for the evolution of perturbed neutron stars and for the accurate identification (via Fourier transforms) of normal modes of oscillation. This is demonstrated for radial and quadrupolar pulsations in the nonrotating limit, where we find good agreement with frequencies obtained with a linear perturbation code. The code can be used for studying small-amplitude or nonlinear pulsations of differentially rotating neutron stars, while our present results serve as testbed computations for three-dimensional general-relativistic evolution codes.

description: Many fathers would like to work less, but they do not reduce their working hours. Studies on the role of workplace organizations for work-family balance point to adverse working conditions as a major obstacle. Quantitative studies, however, are still rare due to the lack of data resources. This paper uses an AID:A add-on survey of 878 parenting couples from 2015 to study the relationships between cultural and structural workplace conditions and fathers’ working times. We differentiate between part-time work, contractual and actual working hours. The results show a robust relationship between fathers’ inclination to work reduced hours and the extent to which formal, universal and transparent policies exist in their workplaces. Perceptions of a strong ideal-worker norm and a supportive culture of temporary replacement are particularly relevant for whether fathers manage to comply with their contractual working hours. Surprisingly, fathers tend to have longer contractual hours, the more they feel supported by their supervisors. The results also indicate that cultural workplace conditions that support shorter working hours of fathers can be found in many economic sectors and companies of different sizes. Zusammenfassung Viele Väter wünschen sich kürzere Arbeitszeiten, setzen diesen Wunsch jedoch nicht um. Studien zur Rolle von Arbeitsorganisationen für die Vereinbarkeit von Familie und Beruf lassen ungünstige betriebliche Rahmenbedingungen als einen wichtigen Hinderungsgrund vermuten. Quantitative Studien stehen mangels Datengrundlage jedoch bislang weitgehend aus. Basierend auf einer AID:A-Zusatzbefragung von 878 Elternpaaren aus dem Jahr 2015 untersucht dieser Beitrag Zusammenhänge zwischen betriebskulturellen und -strukturellen Faktoren und den Arbeitszeiten von Vätern. Dabei differenzieren wir zwischen Teilzeitarbeit, vertraglichen und tatsächlichen Arbeitszeiten. Die Ergebnisse zeigen einen robusten Zusammenhang zwischen dem Ausmaß an formellen, allgemeingültigen und transparenten Regelungen im Betrieb und kürzeren Arbeitszeiten von Vätern. Verfügbarkeits- und Vertretungskulturen sind offenbar besonders dafür relevant, ob vertragliche Arbeitszeiten auch eingehalten werden. Überraschend haben Väter umso längere vertragliche Arbeitszeiten, je stärker sie sich von ihren Vorgesetzten unterstützt fühlen. Die Ergebnisse weisen auch darauf hin, dass günstige kulturelle Rahmenbedingungen für kürzere Arbeitszeiten von Vätern in vielen Branchen und Betrieben unterschiedlicher Größe möglich sind.

description: The social understanding of fatherhood is currently changing. This transition becomes visible not only in cultural concepts of ‘active’ fatherhood but also in new policies and an increasing number of work organizations that address fathers in their offers to reconcile family and a career. In real life, though, employees are still expected to be constantly available and to consent to career norms that reproduce hegemonic masculinities. This is a strong indicator of organizational norms that limit fathers’ capabilities to get involved in the family. In our paper, we argue that hidden rules in organizational culture may counteract official organizational policies of family friendliness. We ask how organizational contexts influence fathers’ sense of entitlement and to what extend these factors are gendered. In our argumentation, we refer to case studies of seven work organizations of different economic sectors. Zusammenfassung Das Verständnis von Vaterschaft hat in den letzten Jahren einen Wandel erfahren, der sich u.a. in veränderten Leitbildern aktiver Vaterschaft und entsprechenden politischen Maßnahmen äußert. Viele Arbeitsorganisationen weiten ihre Vereinbarkeitsprogramme auf Väter aus. Organisationskulturen enthalten jedoch immer noch latente Verfügbarkeitserwartungen und an traditionellen hegemonialen Männlichkeiten orientierte Karrierenormen, die sich negativ auf die Verwirklichung aktiver Vaterschaft auswirken. Wir nehmen an, dass verborgene Regeln im Unternehmensalltag wirksam sind, die offiziellen Unternehmenspolitiken zuwider laufen (können). Unser Beitrag fragt danach, in welcher Weise Organisationskulturen das Anspruchsbewusstsein von Vätern beeinflussen und wie diese Faktoren mit Geschlechternormen interagieren. Empirische Grundlage sind sieben Unternehmensfallstudien aus unterschiedlichen Wirtschaftsbereichen.

description: We present a GPU-based technique for efficient selection in interactive visualizations of large particle datasets. In particular, we address multiple attributes attached to particles, such as pressure, density, or surface tension. Unfortunately, such intermediate attributes are often available only during the simulation run. They are either not accessible during visualization or have to be saved as additional information along with the usual simulation data. The latter increases the size of the dataset significantly, and the required variables may not be known in advance. Therefore, we choose to compute intermediate attributes on the fly. In this way, we are even able to obtain attributes that were not calculated by the simulation but may be relevant for data analysis or debugging. We present an interactive selection technique designed for such attributes. It leverages spatial regions of the selection to efficiently compute attributes only where needed. This lazy evaluation also works for intelligent and data-driven selection, extending the region to include neighboring particles. Our technique is evaluated by measurements of performance scalability and case studies for typical usage examples.
