A Novikov equation describing pseudo‐spherical surfaces, its pseudo‐potentials, and local isometric immersions

We show that an equation discovered in V. Novikov [Generalizations of the Camassa–Holm equation, J Phys A: Math Theor. 2009; 42: paper 342002] describes pseudo‐spherical surfaces and is geometrically integrable. From the geometric structure of the equation we obtain an infinite hierarchy of conservation laws. The problem of local isometric immersions is also considered.
Three-dimensional analytical subthreshold models for bulk MOSFETs

Three-dimensional device-physics-based analytical models are developed for subthreshold conduction in uniformly doped small geometry (i.e., simultaneously short channel and narrow width) bulk MOSFETs, for various isolation schemes. Inverse-narrow width effects, where the threshold voltage decreases with decreasing channel width, are predicted by the model for trench isolated MOSFETs. For LOGOS isolated MOSFETs, conventional narrow width effects, where the threshold voltage increases due to decreasing channel width, are predicted. The narrow width effects are found to be comparable to the short channel effects in the absence of significant applied drain biases. However, for larger drain biases, the short channel effects outweigh the narrow width effects due to the weaker potential perturbation at the device width edges compared to the drain end. Unlike the threshold voltage, the subthreshold swing of the device is found to increase with reduced device dimensions regardless of the isolation scheme since both conventional and inverse narrow width effects result in weaker control of the surface potential by the gate.
EVALUATION OF SHEAR STRENGTH IN COHESIVE SOILS WITH SPECIAL REFERENCE TO SWEDISH PRACTICE AND EXPERIENCE

The paper describes how the Swedish Geotechnical Institute (SGI) currently proceeds in the evaluation of shear strength in cohesive soils. Information is given on how different test results and empirical experience can be weighted and combined to give the best possible estimation of the shear strength properties in cohesive soils. The procedure described has evolved during the continuing work at SGI as research results and practical experience from the Institute as well as others have been obtained and taken into consideration.
IMPACT OF COVID-19 PANDEMIC ON RESIDENCY TRAINING FOR FAMILY MEDICINE ACADEMY TRAINEES, EASTERN PROVINCE, KINGDOM OF SAUDI ARABIA

: Objectives: The family medicine residency program in the eastern province of Saudi Arabia has tried to give trainees the utmost support for coping with the COVID-19 pandemic; however, due to a national need for first responders and the high risk of exposure, training methods and working hours have been drastically changed. This study aimed to assess the impact of those changes. Methods : A cross-sectional study was conducted among residents at the Family Medicine Academy in the E1 Health Cluster in Eastern Province (FMA-EP). All family medicine residents were invited to participate. A self-administered questionnaire was sent out on online platforms. The survey comprised 30 items that measured the impact of the pandemic on residency training. All statistical analyses were performed using SPSS version 21. Results : A total of 126 residents were recruited, 49 (38.9%) were junior residents, and 77 (61.1%) were senior residents. Overall satisfaction with virtual training methods was 68.3%. Approximately 72.2% of trainees did not receive on-site training for the correct use of personal protective equipment (PPE) (p=0.022). Positive impacts were noted for academic requirements completion and submission (p<0.001) and mentorship (p=0.019). Conclusion : The impact of COVID-19 among FMA-EP trainees was evident in this study. However, the trainees were satisfied with virtual training methods. A lag in education and learning is predictable during any pandemic; therefore, embracing smart learning methods is crucial.
Understanding internet routing anomalies and building robust transport layer protocols

As the Internet grows and routing complexity increases, network-level instabilities are becoming more and more common. End-to-end communications are especially susceptible to service disruptions, while diagnosing and mitigating these disruptions are extremely challenging. In this dissertation, we design and build systems for diagnosing routing anomalies and improving robustness of end-to-end communications. The first piece of this work describes PlanetSeer, a novel distributed system for diagnosing routing anomalies. PlanetSeer passively monitors traffic in wide-area services, such as Content Distribution Networks (CDNs) or Peer-to-Peer (P2P) systems, to detect anomalous behavior. It then coordinates active probes from multiple vantage points to confirm the anomaly, characterize it, and determine its scope. There are several advantages of this approach: first, we obtain more complete and finer-grained views of routing anomalies since the wide-area nodes provide geographically-diverse vantage points. Second, we incur limited additional measurement cost since most active probes are initiated when passive monitoring detects oddities. Third, we detect anomalies at a much higher rate than other researchers have reported since the wide-area services provide large volumes of traffic to sample. Through extensive experimental study in the wide-area network, we demonstrate that PlanetSeer is an effective system for both gaining a better understanding about routing anomalies and for providing optimization opportunities for the host service. To improve the robustness of end-to-end communications during performance anomalies, we design mTCP, a novel transport layer protocol that can minimize the impact of anomalies using redundant paths. mTCP separates the congestion control for each path so that it can not only obtain higher throughput but also be more robust to path failures. mTCP can quickly react to failures, and the recovery process normally takes only several seconds. We integrate a shared congestion detection mechanism into mTCP that allows us to suppress paths with shared congestion. This helps alleviate the aggressiveness of mTCP. We also propose a heuristic to find disjoint paths between pairs of nodes. This can minimize the chance of concurrent failures and shared congestion. We implement mTCP on top of an overlay network and evaluate it using both emulations and experiments in the wide-area network.
Single and combined effects of air, road and rail traffic noise on sleep

INTRODUCTION: It is a well known fact that noise annoyance depends on the traffic mode. Much less is known about differences in physiological effects, especially on combined effects. Therefore, we investigated the effects of air (AI), road (RO) and rail (RA) traffic noise on sleep in the AIRORA study. METHODS: 72 subjects (40 ± 13 years, 32 male) were polysomnographically investigated during 11 consecutive nights in the laboratory. Electrophysiological signals included EEG, EOG, EMG, EKG, respiratory movements and finger pulse amplitude. Cortisol and noradrenalin were measured in nocturnal urine samples. Each traffic mode consisted of five noise categories (maximum SPL 45, 50, 55, 60 and 65 dBA) with 8 different noise events, i.e. 40 noise events in total. Therefore, between 40 and 120 noise events were realistically played back during single (AI, RO, RA, RORO), double (AIRO, AIRA, RORA) and triple (AIRORA) exposure nights. The design was complemented with a noise-free control night and carefully balanced. RESULTS: Annoyance due to aircraft noise was stronger compared to both rail and road traffic noise. However, according to multvariable random subject effect logistic regression models, awakening probability increased in the order AI, RO, RA (AI<RO, AI<RA, both p<0.0001; RO<RA, p=0.513). Cumulative effects in double and triple exposure nights were both lower (S1, SWS) and higher (Wake, REM) compared to expectations based on single exposure nights. Nocturnal traffic noise exposure had no influence on stress hormone excretion rates. CONCLUSIONS: Traffic modes differ in their noise effects on sleep. Field studies are needed to validate our results.
Modelling of a transmission tower for lightning-surge analysis

Modelling of transmission towers is an essential part of the travelling-wave analysis of lightning surges in overhead power transmission lines. In this paper, an equivalent distributed constant line model of a transmission tower is developed. The model consists of three parts: main legs; bracings; and crossarms. The surge impedance of each part is expressed by the functions of their dimensions and geometry. This tower model is applied to a 500 kV transmission tower whose surge performance characteristics are measured. It is found that the tower voltage wave shapes, calculated from this model, closely agree with the measured ones. This proves that the authors' proposed tower model simulates well the surge performances of actual transmission towers.
Applicability of shredded tire chips as a lightweight retaining wall backfill in seismic regions

Using shredded tires as an alternative backfill material for retaining walls is an effective method for recycling a common and abundant waste material. In this paper, the engineering properties of the shredded tire from various sources were compiled. Retaining walls were designed for static and seismic conditions using the average properties following load and resistance factor design (LRFD) method and compared with that of conventional granular material. The performance of retaining wall backfilled with shredded tires was then investigated by applying design earthquake acceleration-time histories using advanced finite element software and compared with that of sand backfill. Results show that the shredded tire backfill significantly reduces the wall tip deflection and maximum shear force and bending moment along the wall.
New consistent model for ferrite permeability tensor with arbitrary magnetization state

Partially magnetized ferrites play an important role in a large class of microwave devices. For instance, when the optimal design of circulators, which operate with ferrite in the low magnetic field region, and other ferrite devices (phase shifters, isolators, etc.) are considered, permeability tensor is required for arbitrary magnetization. The existing models do not simultaneously provide all tensor components, and their validity domain is limited. The proposed model provides integral expressions for all permeability tensor components, which can be treated numerically without difficulties. The physical nature of the model enforces the causal aspect that is required when numerical time-domain methods (such as finite-difference time domain (FDTD), transmission-line matrix (TLM), time-domain finite-element method (TDFEM), etc.) are used. Finally, the comparison with measurements or specific cases, which can be treated by available models, demonstrates the validity of the proposed approach.
Tailoring high-temperature stability and electrical conductivity of high entropy lanthanum manganite for solid oxide fuel cell cathodes

High entropy perovskite oxides (HEPOs) have been proposed to serve as improved cathode materials for solid oxide fuel cells (SOFCs); however, the larger compositional design space introduced by HEPOs urges for a better understanding of the correlation among the composition, phase stability and resulting properties for HEPO cathodes. In this work, a series of LaMnO3 based HEPOs (HEALMOs) were designed systematically to investigate the effect of A site high entropy composition on the structure and thermochemical/ electrical properties of the HEALMO materials. The results show that the high entropy effect manifests itself on top of the conventional doping effect. First of all, neither Goldschmidt’s tolerance factor nor the cation size difference can be used simply to predict the formation ability of single-phase HEALMOs. Meanwhile, HEALMOs may adopt higher crystallography symmetry with much higher cation size differences and at Goldschmidt’s tolerance factor values deviated more largely from 1. Secondly, while high-temperature stability including both resistance to elemental segregation and chemical compatibility with 8YSZ is affected by the A site cation size difference in a similar way as for conventional perovskite oxides, HEALMOs show much enhanced stability at larger A site cation size differences. Finally, high entropy contributes to the maintenance of electrical conductivity in the high temperature range. The optimum HEALMO with the composition of (La0.2Nd0.2Sm0.2Ca0.2Sr0.2)MnO3 exhibits the combination of excellent high-temperature stability and good electrical conductivity, highlighting its great potential as a promising cathode material for SOFCs.
Fish as A Source of Micronutrients In Preventing The Risk of Pre-Eclampsia In Pregnant Women

Introduction: Pre-eclampsia is a pregnancy complication that is still a contributor to maternal and fetal deaths. Pre-eclampsia can be prevented by adopting a healthy lifestyle, which includes the fulfillment of nutritional needs during pregnancy. Fish can be a source of micronutrients for pregnant women to prevent pre-eclampsia. Methods: The research design used was correlational with a cross-sectional approach. This study aims to analyze the consumption of fish-based nutrition as a source of adequate micronutrients in preventing pre-eclampsia in pregnant women. Data were obtained through questionnaires, structured interviews with a retrospective approach about fish consumption patterns during pregnancy. The sample used was 116 pregnant women in the third semester of the basic service in Jember Regency. Sampling was carried out with a questionnaire prepared by the researcher by modifying the FFQ (food frequency questioner) questionnaire in the last three months, in addition to observation/examination was also carried out to see the condition of the mother's pregnancy, structured interviews, and documentary studies for pre-eclampsia diagnosis. Data analysis was carried out by quantitative analysis using chi-square. Results : The results showed that there was a relationship between fish-based nutrition consumption and the incidence of pre-eclampsia. P-value 0.014 with OR 2.69 and 95% CI 1.208-5.634. Micronutrient deficiency is the cause of the increasing cases of pre-eclampsia during pregnancy. Conclusion: Support from all parties is needed so that pregnant women can consume fish that are safe and still hygienic and healthy in supporting their pregnancy.
Multimedia assisted instruction in upper level engineering courses

The central idea in an engineering biotechnology course is to treat, within a single course, all significant scientific and engineering issues that encompass converting genes, the starting material, to a final product that is manufactured for the market place. In the authors' view, it is important to tell the whole story in a single course with sufficient depth so that the relevancy and significance of the emerging area of biotechnology can be communicated effectively. To assist them in covering a broad topic area, they resorted to binding the topic thematically and also developed self-standing multimedia lectures which are distributed on a CD-ROM.
Anti-inflammatory agents other than corticosteroid in SARs-CoV-2 pneumonia

The SARs-CoV-2 results in hyperinflammation among infected patients. This condition leads to serious organ injury, especially in the lungs. Therefore, the main treatment option, in addition to anti-viral agents, is the administration of corticosteroids. However, in many cases, inadequate response to corticosteroids has been observed—other anti-inflammatory agents, such as interleukin-6 inhibitor, kinase inhibitor, etc., play an essential role in reducing this severe complication.
An empirical study of hybrid inspection systems and allocation of inspection functions

With the demand for zero-defect products and the requirement of shorter lead-time production, designs of inspection systems have changed from using sampling inspection and human inspectors to 100% inspection and automated inspection systems. Unfortunately, automated inspection systems usually cannot meet the required performance without some human intervention. The objectives of this research are to demonstrate the feasibility of hybrid inspection systems, to compare these systems with the unaided human system and unaided automated inspection systems, and to develop a framework to allocate humans and computers in an inspection system in order to achieve the best system performance. This research found that a hybrid inspection system had better performance than either human inspection or entirely automated inspection systems. A proposed function allocation procedure was found to be feasible.
Modern library technologies for data storage, retrieval and use

as well as to the already great wealth of most of the Internet. There can be problems, however, due to screen size and operating system that can restrict access to some of this content. Libraries must ensure that their content is not only usable by these devices, but also appealing so that users want to access the content and are able to do so, regardless of the device they use. Libraries have a choice of how to present their content for mobile devices, but whether to opt for mobile accessible websites or apps is up to each library to decide. Mobile library services is a compilation of papers on library mobile projects, from app creation to responsive web design, mobile devices and strategies. It documents the experiences of academic, public and a special library in their expansion of service into mobile accessibility. The projects include catalogues, citations, databases, discovery and more. Each chapter provides good overview information on the project discussed, ranging from its rationale, through resourcing and onto creation and then promotion, use and evaluation. The projects included cover a wide range of options and a variety of library types and needs. They are detailed without being overwhelming and provide more than enough information to understand the nature of the project and its conclusion. All the papers have been written by people directly involved in each project. Helpful supporting information in the form of screen shots, flow charts and more helps to give a clear picture of what was done. Although each project included was ultimately successful, the papers include issues and problems that arose during the process and outline the solutions considered and implemented. Many also present the lessons they learned and their future directions. For those considering such a project, it is well worth investing in this title in order to learn from the experiences of others. Librarians are very good at sharing solid, useful information, which is again apparent in the collection of papers in Mobile library services.
Hybrid Approach to the Study of Inter-Organization High Performance Teams

AbstractAs construction projects increase in scale and complexity, a major challenge is to ensure the effective transfer of relevant information to the right entities to make decisions, manage conflict, and solve challenges, which will allow organizations to achieve the goals of the project. Project teams whose members have the necessary attitudes, competencies, and skills to overcome this challenge are often termed high performing teams (HPTs). Building on recent studies about HPTs, this paper proposes a hybrid methodology that uses network theory and the jobs-to-be-done framework for the study of teams that aspire to develop high performance. Social network analysis (SNA) provides a reactive approach to the study of team connectivity and hierarchical leadership patterns and is complemented by the jobs-to-be-done framework that focuses on the drivers of the behavior of the various project organizations. The paper demonstrates these concepts by analyzing the characteristics of HPTs through a case study on.
Social environment shapes female settlement decisions in a solitary carnivore

Abstract How and where a female selects an area to settle and breed is of central importance in dispersal and population ecology as it governs range expansion and gene flow. Social structure and organization have been shown to influence settlement decisions, but its importance in the settlement of large, solitary mammals is largely unknown. We investigate how the identity of overlapping conspecifics on the landscape, acquired during the maternal care period, influences the selection of settlement home ranges in a non-territorial, solitary mammal using location data of 56 female brown bears (Ursus arctos). We used a resource selection function to determine whether females’ settlement behavior was influenced by the presence of their mother, related females, familiar females, and female population density. Hunting may remove mothers and result in socio-spatial changes before settlement. We compared overlap between settling females and their mother’s concurrent or most recent home ranges to examine the settling female’s response to the absence or presence of her mother on the landscape. We found that females selected settlement home ranges that overlapped their mother’s home range, familiar females, that is, those they had previously overlapped with, and areas with higher density than their natal ranges. However, they did not select areas overlapping related females. We also found that when mothers were removed from the landscape, female offspring selected settlement home ranges with greater overlap of their mother’s range, compared with mothers who were alive. Our results suggest that females are acquiring and using information about their social environment when making settlement decisions.
