description: Shape2SAS is a web application that allows researchers and students to build intuition and understanding of small-angle scattering. It is available at https://somo.chem.utk.edu/shape2sas. The user defines a model of arbitrary shape by combining geometrical subunits, and Shape2SAS then calculates and displays the scattering intensity, the pair distance distribution as well as a visualization of the user-defined shape. Simulated data with realistic noise are also generated. We demonstrate how Shape2SAS can calculate and display the different scattering patterns for various geometrical shapes, such as spheres and cylinders. We also demonstrate how the effect of structure factors can be visualized. Finally, we show how multi-contrast particles can readily be generated, and how the calculated scattering may be used to validate and visualize analytical models generated in analysis software for fitting small-angle scattering data.

description: Active magnetic bearings are used in a number of applications but their disadvantage is the high asynchronous error due to sensor noise amplification. In this paper a new radial position sensor for active magnetic bearings (AMB) based on linear optical encoders is presented. A commercial encoder scanning head faces a round scale with concentric, coplanar lines on its face. Because such a scale is not readily available, it is made by high precision micro machining and different options are compared. In experiments a measurement noise of 3.5 nm at 10 kHz bandwidth is achieved. In addition, a magnetic bearing is built to demonstrate the sensor in closed-loop.

description: В статье рассмотрены актуальные аспекты правового регулирования вопросов, связанных с организацией детского отдыха. В качестве базовой формы организации детского отдыха и проведения оздоровительных мероприятий рассмотрен детский лагерь. Данная форма может осуществлять организацию детского отдыха в различных режимах, однако отмечается наличие общих нормативных требований к педагогическому и медико-социальному сопровождению работы с детьми. На основании панорамного анализа требований к организации детского отдыха сделан вывод о фрагментарном и разрозненном характере правового регулирования в данной сфере. Правовые нормы, регламентирующую организацию детского отдыха, имеют различную отраслевую принадлежность. При этом отмечается факт консолидации специализированных правовых норм в данной области преимущественно на подзаконном уровне. Также в статье делается вывод о наличии некоторой рассогласованности в понимании содержания используемых в законодательстве дефиниций, а также ошибочной трактовке статуса лагеря как обособленного юридического лица. Сделан вывод о том, что присутствие правовых норм, регламентирующих организацию детского отдыха, в различных ведомственных актах снижает эффективность правового регулирования в данной сфере, что может негативным образом сказываться на обеспечении безопасности и здоровья детей. Конструктивным направлением развития правового регулирования в области организации детского отдыха и оздоровления предлагается рассматривать разработку и принятие специализированного законодательного акта на федеральном уровне, посредством которого была бы осуществлена консолидация правовых норм различной отраслевой принадлежности.
Real-Time Viewport-Aware Optical Flow Estimation in 360-degree Videos for Visually-Induced Motion Sickness Mitigation

description: Visually-induced motion sickness (VIMS), a side effect of perceived motion caused by visual stimulation, is a major obstacle to the widespread use of Virtual Reality (VR). Along with scene object information, visual stimulation can be primarily indicated by optical flow, which characterizes the motion pattern, such as the intensity and direction of the moving image. We estimated the real time optical flow in 360-degree videos targeted at immersive user interactive visualization based on the user's current viewport. The proposed method allows the estimation of customized visual flow for each experience of dynamic 360-degree videos and is an improvement over previous methods that consider a single optical flow value for the entire equirectangular frame. We applied our method to modulate the opacity of granulated rest frames (GRFs), a technique consisting of visual noise-like randomly distributed visual references that are stable to the user's body during immersive pre-recorded 360-degree video experience. We report the results of a pilot one-session between-subject study with 18 participants, where users watched a 2-minute high-intensity 360-degree video. The results show that our proposed method successfully estimates optical flow, with pilot data showing that GRFs combined with real-time optical flow estimation may improve user comfort when watching 360-degree videos. However, more data are needed for statistically significant results.

description: The viscosity of an optical fibre over 1000 to 1150 °C is studied by inscribing an optical fibre Bragg grating that can withstand temperatures up to 1200 °C and monitoring fibre elongation under load through the Bragg wavelength shift. This optical interrogation offers high accuracy and reliability compared to direct measurements of elongation, particularly at lower temperatures, thus avoiding significant experimental error. An excellent Arrhenius fit is obtained from which an activation energy for viscous flow of Ea = 450 kJ/mol is extracted; addition of an additional temperature dependent pre-exponential does not change this value. This value is less than that idealised by some literature but consistent with other literature. The log plot of viscosity is overall found to be consistent with that reported in the literature for silica measurements on rod and beams, but substantially higher to past work reported for optical fibres. The discrepancy from an idealised activation energy Ea ~ 700 kJ/mol may be explained by noting the higher fictive temperature of the fibre. On the other hand, past optical fibre results obtained by beam bending with much lower values leave questions regarding the method of viscosity measurement and the time taken for structural equilibration. We note that because regenerated gratings already involve post-annealing to stabilise their operation at higher temperature, the structures are much more relaxed compared to normal fibres. This work highlights the need to stabilize components for operation in harsh environments before their application, despite some mechanical compromise. Given the increasing expectation of all-optical waveguide technologies operating above 1000 °C, the need to study the behaviour of glass over the long term brings added significance to the basic understanding of glass in this regime.

description: We show that the optimal packing of hard spheres in an infinitely long cylinder yields structures characterised by a screw symmetry. Each packing can be assembled by stacking a basic unit cell ad infinitum along the length of the cylinder with each subsequent unit cell rotated by the same twist angle with respect to the previous one. In this paper we quantitatively describe the nature of this screw operation for all such packings in the range 1 <= D/d <= 2.715 and also briefly discuss their helicity.

description: EuCd$_2$As$_2$ is now widely accepted as a topological semimetal in which a Weyl phase is induced by an external magnetic field. We challenge this view through firm experimental evidence using a combination of electronic transport, optical spectroscopy and excited-state photoemission spectroscopy. We show that the EuCd$_2$As$_2$ is in fact a semiconductor with a gap of 0.77 eV. We show that the externally applied magnetic field has a profound impact on the electronic band structure of this system. This is manifested by a huge decrease of the observed band gap, as large as 125~meV at 2~T, and consequently, by a giant redshift of the interband absorption edge. However, the semiconductor nature of the material remains preserved. EuCd$_2$As$_2$ is therefore a magnetic semiconductor rather than a Dirac or Weyl semimetal, as suggested by {\em ab initio} computations carried out within the local spin-density approximation.

description: In this work, we present a method to extract the skeleton of a self-occluded tree canopy by estimating the unobserved structures of the tree. A tree skeleton compactly describes the topological structure and contains useful information such as branch geometry, positions and hierarchy. This can be critical to planning contact interactions for agricultural manipulation, yet is difficult to gain due to occlusion by leaves, fruits and other branches. Our method uses an instance segmentation network to detect visible trunk, branches, and twigs. Then, based on the observed tree structures, we build a custom 3D likelihood map in the form of an occupancy grid to hypothesize on the presence of occluded skeletons through a series of minimum cost path searches. We show that our method outperforms baseline methods in highly occluded scenes, demonstrated through a set of experiments on a synthetic tree dataset. Qualitative results are also presented on a real tree dataset collected from the field.

description: Вопрос финансирования футбольных клубов в России встал наиболее остро после пандемии коронавируса и последовавших ограничений в 2020-2021 годах, а также санкций Союза европейских футбольных ассоциаций (далее – УЕФА) по отношению к российскому футболу, наложенных в начале 2022 года (отстранение от соревнований и дозволение футболистам в одностороннем порядке приостанавливать действующие контракты с клубами Российской премьер-лиги (далее-РПЛ)). Многие российские клубы столкнулись с огромными финансовыми трудностями, а некоторые и вовсе стали банкротами. Связано это во многом с существующей системой финансирования профессионального футбола в РФ, а точнее её зависимости от государственного бюджета. На сегодняшний день большинство клубов в России государственные или принадлежат госкорпорациям, многие из них убыточные и не способствуют развитию футбола в России. При этом какие-либо шаги в направлении привлечение частного бизнеса в футбольную сферу, который способен за счет создания конкуренции ускорить прогресс российского футбола, не предпринимаются. В данной статье рассмотрена существующая система финансирования футбольных профессиональных клубов в России, выделены её плюсы и минусы, а также сделаны аргументированные предложения по реформированию данной системы с целью повышения её эффективности, основанные на зарубежной практике, мнении ученых и личного видения авторов. При написании настоящей работы были использованы общенаучные методы познания, такие как обобщение, анализ, синтез, сравнение. Также применялись специальные методы познания, такие как сравнительно-правовой и логический. Применение перечисленных методов в совокупности позволило осуществить подробный анализ финансовой системы российского футбола и определить перспективы его развития.

description: EMV Simulation ist ein sehr anspruchsvolles, wertvolles und mächtiges Werkzeug für EMV Spezialisten. Wenn dieses Werkzeug nicht nur für einzelne individuelle Analysen, sondern auch als fester Bestandteil bei der Produktentwicklung komplexer Systeme verwendet werden soll, bedarf es einer Vielzahl an Voraussetzungen und Befähigungen. Dieser Fachartikel behandelt Fragestellungen und Lösungen, wie die EMV Simulation in den Entwicklungsprozess von Kraftfahrzeugen erfolgreich integriert werden kann. Es wird diskutiert, warum die EMV Systemsimulation im Vergleich zur etablierten Crash Berechnung bei der Demokratisierung nicht mithalten kann. Anschließend wird der operative Simulationsprozess beschrieben, welcher sich aus der Datenbeschaffung, Modellierung, Berechnung und Auswertung zusammensetzt. Damit der Prozess funktionieren kann, werden Befähigungen benötigt. Zu den Befähigungen gehört ein professionelles Datenmanagement System, eine durchgängige Toolkette, abgestimmte synchronisierte Projektpläne des Gesamtsystems, fest definierte Simulationslastfälle und eine durchgängige Verifikations- und Validierungsstrategie. Wenn der Prozess definiert und die Befähigungen sichergestellt sind, kann der Aufwand dem Nutzen gegenübergestellt werden, um den neuen Prozess zu bewerten.

description: In dieser Arbeit wurde eine Feldsimulationsmethode vorgestellt, um die Impedanz von Traktionsbatterien bei hohen Frequenzen zu bestimmen. Bei der Methode wird die Batteriezelle als 3D-Modell konstruiert, wobei ihre innere Struktur aus Mischelektroden mit Elektrolyten und Separator als homogenes festes Material modelliert wird. Nach der Definition der elektrischen Eigenschaften dieses Materials, kann die Simulation die Impedanz der komplexen Zelle liefern. Zum Bilden eines HV-Batteriesystems, werden mehrere Simulationsmodellzellen in Reihe geschaltet. Das Verfahren war in der Lage, genaue Ergebnisse für Batteriezellen und deren Netzwerke zu liefern. Mit dieser Methode konnten die asymmetrische Impedanz und die Gegentaktimpedanz der Traktionsbatterie bestimmt werden. Die Ergebnisse wurden von 20 kHz bis 110MHz für Einzelzellen und bis 5MHz für die Traktionsbatterie verglichen. Es wurde eine gute Übereinstimmung zwischen Simulationen und Messungen erzielt. Mit dieser Methode ist es möglich, das EMV-Verhalten von Batterien zu beobachten und vorherzusagen.

description: Цифровизация экономических процессов в России выводит проблематику правового регулирования энергетики на новый уровень. Перед правовой наукой стоит технологический вызов, связанный с необходимостью внедрения новых технологий и правового регулирования их использования в гражданском обороте. Особенное место данная проблема занимает в сегменте регенеративной энергетики, где правовой режим генерирующих объектов определяется через призму подзаконных актов, а не энергетического законодательства. Целью статьи является анализ особенностей правового режима генерирующих объектов, функционирующих на основе возобновляемых источников энергии. Достоверность полученных результатов обеспечивается теоретическим анализом научной литературы, анализом нормативно-правовых актов, сравнительным анализом, анализом отечественного и зарубежного опыта. Научная новина заключается в раскрытии специфики правового режима генерирующих объектов, использующих регенеративные источники энергии. Автор пришел к выводу о том, что функциональная модель правового режима следует определять как фрагментарную, которая распространяется на частноправовые и публичные правоотношения. По большинству аспектов правовой режим генерирующих объектов регулируется подзаконными актами министерств и ведомств, устанавливающих организационные процедуры, определяющие порядок функционирования таких объектов. Основные проблемы создают нормы, определяющие порядок экономической поддержки генерирующих объектов.

description: Recent advances in deep learning have improved the performance of many Natural Language Processing (NLP) tasks such as translation, question-answering, and text classification. However, this improvement comes at the expense of model explainability. Black-box models make it difficult to understand the internals of a system and the process it takes to arrive at an output. Numerical (LIME, Shapley) and visualization (saliency heatmap) explainability techniques are helpful; however, they are insufficient because they require specialized knowledge. These factors led rationalization to emerge as a more accessible explainable technique in NLP. Rationalization justifies a model's output by providing a natural language explanation (rationale). Recent improvements in natural language generation have made rationalization an attractive technique because it is intuitive, human-comprehensible, and accessible to non-technical users. Since rationalization is a relatively new field, it is disorganized. As the first survey, rationalization literature in NLP from 2007-2022 is analyzed. This survey presents available methods, explainable evaluations, code, and datasets used across various NLP tasks that use rationalization. Further, a new subfield in Explainable AI (XAI), namely, Rational AI (RAI), is introduced to advance the current state of rationalization. A discussion on observed insights, challenges, and future directions is provided to point to promising research opportunities.

Privacy-Aware Load Balancing in Fog Networks: A Reinforcement Learning Approach

Publisher: name: arXiv
Year: 2023
Subjects: subject: Distributed, Parallel, and Cluster Computing (cs.DC)

description: In this paper, we propose a load balancing algorithm based on Reinforcement Learning (RL) to optimize the performance of Fog Computing for real-time IoT applications. The algorithm aims to minimize the waiting delay of IoT workloads in dynamic environments with unpredictable traffic demands, using intelligent workload distribution. Unlike previous studies, our solution does not require load and resource information from Fog nodes to preserve the privacy of service providers, who may wish to hide such information to prevent competitors from calculating better pricing strategies. The proposed algorithm is evaluated on a Discrete-event Simulator (DES) to mimic practical deployment in real environments, and its generalization ability is tested on simulations longer than what it was trained on. Our results show that our proposed approach outperforms baseline load balancing methods under different workload generation rates, while ensuring the privacy of Fog service providers. Furthermore, the environment representation we proposed for the RL agent demonstrates better performance compared to the commonly used representations for RL solutions in the literature, which compromise privacy.

Clinically indicated replacement versus routine replacement of peripheral intravenous catheters: a quality improvement project comparing phlebitis rates
Creators: name: Galluzzo, Karen
Publisher: name: No Publisher Supplied
Year: 2023

description: PURPOSE: Peripheral intravenous catheter insertion is the most common invasive procedure for hospital inpatients. Guidelines developed by the CDC are outdated and recommend PIVs be changed every 3 days. This DNP project aims to determine if implementing a QI project allowing PIVs to remain in-situ until no longer clinically viable will increase phlebitis rates.METHODOLOGY: A hospital-wide QI project was initiated in a NJ hospital. Recruitment involved use of the EMR, sampling 30 patients pre and post-implementation for a retrospective chart review. The evaluation focused on phlebitis scores, comparing those left in-situ both less and more than 96 hours. Information on the policy change was disseminated using an email practice flash and flyers were posted in each clinical unit. Infection prevention rounded to reinforce the change, and orientation of new hires incorporated the change into their training. Factors for exclusion were age less than 18 years, diagnosis of sepsis, catheters placed in the field, and vesicant infusate.RESULTS: The rates of phlebitis for PIVs allowed to remain in-situ until no longer clinically viable did not increase after implementation of the QI project but is inconclusive due to a lack of data points in the nursing documentation. 95% of the charts did not have a documented reason for removing the line before 30 days. 20% had no removal date or time listed. 40% had vesicants infusing, but 100% did not have the infusing medication linked to the line it was running through.IMPLICATIONS FOR PRACTICE: The recommendation for routine replacement of PIVs should be reevaluated, considering the increased compliance of nursing sterile technique and the innovations of PIV materials, while also noting the additional cost and discomfort for the patient. A limitation of the study is that although phlebitis scores were listed as zero, the reason for early line removal was not documented. Another limitation of the data collection was the inability to accurately incorporate the project’s exclusion criteria, due to a lack of line linking. These limitations will positively impact the importance of nursing documentation, PIV assessment skills, the need for advanced ultrasound-guided lines, and IV fluid site line linking.

description: By means of N-body simulations, we show that radial migration in galaxy disks, induced by bar and spiral arms, leads to significant azimuthal variations in the metallicity distribution of old stars at a given distance from the galaxy center. Metals do not show an axisymmetric distribution during phases of strong migration. Azimuthal variations are visible during the whole phase of strong bar phase, and tend to disappear as the effect of radial migration diminishes, together with a reduction in the bar strength. These results suggest that the presence of inhomogeneities in the metallicity distribution of old stars in a galaxy disk can be a probe of ongoing strong migration. Such signatures may be detected in the Milky Way by Gaia (and complementary spectroscopic data), as well as in external galaxies, by IFU surveys like CALIFA and ATLAS3D. Mixing - defined as the tendency toward a homogeneous, azimuthally symmetric, stellar distribution in the disk - and migration turns out to be two distinct processes, the effects of mixing starting to be visible when strong migration is over.

description: The central parsec of the Milky Way is a very special region of our Galaxy; it contains the supermassive black hole associated with Sgr A* as well as a significant number of early-type stars and a complex structure of streamers of neutral and ionized gas, within two parsecs from the centre, representing a unique laboratory. We report the identification of a high velocity compact nebular filament 2.2 arcsec south of Sgr A*. The structure extends over ~1 arcsec and presents a strong velocity gradient of ~200 km s^{-1} arcsec^{-1}. The peak of maximum emission, seen in [Fe III] and He I lines, is located at dα = +0.20 +/- 0.06 arcsec and dδ = -2.20 +/- 0.06 arcsec with respect to Sgr A*. This position is near the star IRS 33N. The velocity at the emission peak is Vr = -267 km s^{-1}. The filament has a position angle of PA = 115{\degr} +/- 10{\degr}, similar to that of the Bar and of the Eastern Arm at that position. The peak position is located 0.7 arcsec north of the binary X-ray and radio transient CXOGX J174540.0-290031, a low-mass X-ray binary with an orbital period of 7.9 hr. The [Fe III] line emission is strong in the filament and its vicinity. These lines are probably produced by shock heating but we cannot exclude some X-ray photoionization from the low-mass X-ray binary. Although we cannot rule out the idea of a compact nebular jet, we interpret this filament as a possible shock between the Northern and the Eastern Arm or between the Northern Arm and the mini-spiral "Bar".

description: В статье автор делает вывод о том, что в российских работах по конституционному праву зарубежных стран происхождение термина «собственность» в иностранных языках не исследуется. Однако, как будет показано далее, для правильного понимания ряда аспектов конституционного регулирования собственности в зарубежных странах этот вопрос далеко не маловажен. В работах на европейских языках происхождение термина иногда рассматривается, но применительно к языку носителя. Однако в силу общности латинских источников происхождения для носителей наиболее распространенных европейских языков этого достаточно.

description: Milling of ferrous metals is usually performed by applying cemented carbide tools due to their high hardness, temperature and wear resistance. Recently, ceramic tool materials have been on the rise and enhanced the efficiency in machining. As ceramics are brittle-hard materials, tool manufacturing requires a sound knowledge in order to meet the tool requirements such as sharp cutting edges and wear resistance. In this study, milling tools made of the high performance ceramic SiAlON were compared to tools made from cemented carbide. For both tool materials, the influence of a prepared cutting edge was investigated. Both the tool manufacturing process and the cutting edge preparation processes are presented, followed by the application of those tools within milling experiments. In order to evaluate the efficiency of both tool types, the cutting forces and the cumulative process energy demand were analyzed. Additionally, surface roughness of the machined workpieces and tool wear were examined. It was found that the ceramic tools, although process forces were higher than for cemented carbide tools, exhibited by far lower energy consumption, less tool wear and finally generated lower surface roughness. © 2020, The Author(s).

description: The observation of magnetic ordering in atomically thin CrI$_3$ and Cr$_2$Ge$_2$Te$_6$ monolayers has aroused intense interest in condensed matter physics and material science. Studies of van de Waals two-dimensional (2D) magnetic materials are of both fundamental importance and application interest. In particular, exciton-enhanced magneto-optical properties revealed in CrI$_3$ and CrBr$_3$ monolayers have expanded the understanding of exciton physics in 2D materials. Unlike CrI$_3$ and CrBr$_3$ with out-of-plane magnetization, CrSBr has an in-plane magnetic moment, therefore, providing a good opportunity to study the magnetic linear dichroism and high-order magneto-optical effects. Here, based on the many-body perturbation method within density-functional theory, we have studied quasiparticle electronic structure, exciton, and optical properties in CrSBr monolayer. Strongly bounded exciton has been identified with the first bright exciton located at 1.35 eV, in good agreement with an experiment of photoluminescence (Nat. Mater. \textbf{20}, 1657 (2021)). Strong contrast in the optical absorption is found between the electric fields lying along the in-plane two orthogonal directions. In accordance with a typical and realistic experimental setup, we show that the rotation angle of linear polarized light, either reflected or transmitted, could be comparable with those revealed in black phosphorene. Such large linear dichroism arises mainly from anisotropic in-plane crystal structure. The magnetic contribution from the off-diagonal component of dielectric function to the linear dichroism in CrSBr is negligible. Our findings not only have revealed excitonic effect on the optical and magneto-optical properties in 2D ferromagnet CrSBr, but also have shown its potential applications in 2D optics and optoelectronics.

A three-dimensional atomistic kinetic Monte Carlo study of dynamic solute-interface interaction

description: A three-dimensional atomistic Kinetic Monte Carlo model was developed and used to study the interaction between mobile solutes and a migrating interface. While the model was developed with a simplified energetic and topological description, it was also constructed to capture, in the absence of solute, the Burke-Turnbull model for interface migration and, in the presence of solutes, solute segregation to different types of interface sites. After parameterizing the model, simulations were performed to study the relationship between average interface velocity and imposed driving pressure for varying solute concentration and solute diffusivity. While the effect of solute concentration on solute drag pressure was found to be consistent with classical solute drag models, the effect of solute diffusivity was found to give a response not captured by either continuum or previously reported two-dimensional atomistic models. The dependence of maximum drag pressure on solute diffusivity was observed and attributed to the coupling between the structure of a migrating interface and the ability for solute to remain segregated to the interface.

description: We study the problem of online learning and online regret minimization when samples are drawn from a general unknown non-stationary process. We introduce the concept of a dynamic changing process with cost $K$, where the conditional marginals of the process can vary arbitrarily, but that the number of different conditional marginals is bounded by $K$ over $T$ rounds. For such processes we prove a tight (upto $\sqrt{\log T}$ factor) bound $O(\sqrt{KT\cdot\mathsf{VC}(\mathcal{H})\log T})$ for the expected worst case regret of any finite VC-dimensional class $\mathcal{H}$ under absolute loss (i.e., the expected miss-classification loss). We then improve this bound for general mixable losses, by establishing a tight (up to $\log^3 T$ factor) regret bound $O(K\cdot\mathsf{VC}(\mathcal{H})\log^3 T)$. We extend these results to general smooth adversary processes with unknown reference measure by showing a sub-linear regret bound for $1$-dimensional threshold functions under a general bounded convex loss. Our results can be viewed as a first step towards regret analysis with non-stationary samples in the distribution blind (universal) regime. This also brings a new viewpoint that shifts the study of complexity of the hypothesis classes to the study of the complexity of processes generating data.
