Trust in FPGA-accelerated Cloud Computing

Platforms combining Central Processing Systems (CPUs) with Field Programmable Gate Arrays (FPGAs) have become popular, as they promise high performance with energy efficiency. This is the result of the combination of FPGA accelerators tuned to the application, with the CPU providing the programming flexibility. Unfortunately, the security of these new platforms has received little attention: The classic software security assumption that hardware is immutable no longer holds. It is expected that attack surfaces will expand and threats will evolve, hence the trust models, and security solutions should be prepared. The attacker model should be enhanced and consider the following three basic entities as the source of threats: applications run by users, accelerators designed by third-party developers, and the cloud service providers enabling the computation on their platforms. In our work, we review current trust models and existing security assumptions and point out their shortcomings. We survey existing research that target secure remote FPGA configuration, the protection of intellectual property, and secure shared use of FPGAs. When combined, these are the foundations to build a solution for secure use of FPGAs in the cloud. In addition to analysing the existing research, we provide discussions on how to improve it and disclose various concerns that have not been addressed yet.
DEM Void Filling Based on Context Attention Generation Model

The digital elevation model (DEM) generates a digital simulation of ground terrain in a certain range with the usage of 3D point cloud data. It is an important source of spatial modeling information. Due to various reasons, however, the generated DEM has data holes. Based on the algorithm of deep learning, this paper aims to train a deep generation model (DGM) to complete the DEM void filling task. A certain amount of DEM data and a randomly generated mask are taken as network inputs, along which the reconstruction loss and generative adversarial network (GAN) loss are used to assist network training, so as to perceive the overall known elevation information, in combination with the contextual attention layer, and generate data with reliability to fill the void areas. The experimental results have managed to show that this method has good feature expression and reconstruction accuracy in DEM void filling, which has been proven to be better than that illustrated by the traditional interpolation method.
Longitudinal examination of weight-for-length and developmental screening results in infancy and toddlerhood

ABSTRACT The current study examined whether high infant weight-for-recumbent-length (WFL) percentile (i.e., ≥ 85th percentile) at 6 months of age longitudinally related to motor skills, problem solving, and personal/social outcomes on a developmental screener (Ages and Stages Questionnaire-3) at 9 months and 18 months of age. Data were extracted from the medical record at a primary care clinic serving primarily low income and racial minority infants (n = 538). WFL category at 6 months was not related to developmental screener outcomes at 9 or 18 months in both unadjusted analyses and adjusted analyses controlling for relevant covariates.
Prevalence of Hepatitis B Virus and Hepatitis C Virus Among Blood Donors in Nekemte Blood Bank, Western Oromia, Ethiopia: Retrospective 5 Years Study

Background Hepatitis B virus and hepatitis C virus are the greatest threats to blood safety for the recipient. This study aimed to determine the seroprevalence and trends of HBV and HCV infections among blood donors over a period of 5 years at Nekemte blood bank, Ethiopia. Methods A retrospective study was conducted from January 2015 to December 2019 at Nekemte blood bank. The recorded blood donors’ history and laboratory tests were reviewed by data collectors analyzed with Statistical Package for the Social Sciences version 20 software. A p-value of less than 0.005 was considered statistically significant. Results A total of 17,810 consecutive blood donors were screened between January 2015 and December 2019. The seroprevalence of HBV and HCV was 3.06% and 0.64%, respectively. The prevalence of HBV was significantly associated with male (AOR: 2.51; 95% CI: 1.17, 2.91), unmarried (AOR: 2.81; 95% CI: 1.79, 2.51) and rural (AOR: 2.11; 95% CI: 1.17, 3.05) blood donors. The prevalence of HCV was significantly associated with blood donor those were male (AOR: 3.01; 95% CI: 1.17, 3.91), within 45–65 years of age (AOR: 3.56: 95% CI: 1.14, 3.99) and unmarried (AOR: 3.14; 95% CI: 1.65, 3.96). Conclusion The current study shows the prevalence of hepatitis B virus was higher among study participants. However, the prevalence of HCV was low compared to the study conducted in other countries in Africa, a substantial percentage of the blood donors harbor HCV infections. Therefore, it is recommended to increase awareness of people (particularly on unmarried, male and rural resident) on modes of transmission and prevention of infection could help in reducing the burden of both HBV and HCV.
Swearing in The Wolf of Wall Street: A Pragmatic Study

Although swearing is considered as an offensive act, it frequently occurs in movies which represent an instance of everyday conversation. It is the use of language to express a spectrum of emotions such as anger, frustration and annoyance. It also infuses intimacy, solidarity and jocularity. The present study tries to explore swearing from a pragmatic perspective taking the context in which it occurs into account. It also investigates its pragmatic functions, the reasons underlie the use of swear words and the different categories of swearing used in Martin Scorsese’s The Wolf of Wall Street. Besides, the study aims at developing an eclectic model to be used for data analysis.
Lake Morphometry and River Network Controls on Evasion of Terrestrially Sourced Headwater CO2

Lakes are central components of the inland water system distinct from, yet inextricably connected to, river networks. Currently, existing network‐scale biogeochemistry research, although robust, typically treats each of these components separately or reductively. Here, we incorporate lake morphometry into a fully connected stream/lake network for the Connecticut River watershed and model potential evasion of terrestrially sourced headwater CO2 as transported through the network, ignoring in‐stream production. We found that approximately 25%–30% of total potential soil CO2 evasion occurs in lakes, and percent evasion is inversely related to streamflow. A lake's ability to evade CO2 is controlled by residence time and size: most lakes with residence time over 7 days or surface area greater than 0.004 km2 evade functionally all terrestrial CO2 entering from upstream, precluding further downstream transport. We conclude that lakes are important for soil CO2 degassing and that this coupled river/lake approach is promising for CO2 studies henceforth.
Método de estimação de velocidade e posição rotórica da máquina BLDC a partir de uma estrutura PSD+PLL

This work presents a sensorless control strategy for the BLDC machine based on a PSD+PLL (positive sequence detector + phase-locked loop) approach. Due to the non-sinusoidal characteristic of the back-emf, conventional model-based methods can result in errors when estimating the speed and position of the BLDC machine in vector control. To avoid this, the back-emf waveform will be initially reconstructed using a Luenberger observer on the stationary reference frame. A positive sequence detector (PSD) with a frequency adapter will be used in the observed back-emf, making it possible to obtain the fundamental frequency component and eliminating the harmonic components of the back-emf. A phase-locked loop (PLL) adjusted by a PI controller will be used in the positive sequence components to estimate the position and speed of the machine. Simulation results will demonstrate that the estimation of position and speed through positive sequence components presents superiority when compared to the quantities obtained directly by the real back-emf. Resumo: Este trabalho apresenta uma estratégia de controle sensorless para a máquina BLDC baseado em uma abordagem PSD+PLL (positive sequence detector + phase-locked loop). Devido a caracteŕıstica não-senoidal da força contra-eletromotriz (FCEM), métodos convencionais baseados em modelo podem resultar em erros na estimação de velocidade e posição da máquina BLDC no acionamento vetorial. Para contornar este problema, a forma de onda da FCEM inicialmente será reconstrúıda utilizando um observador de Luenberger em eixos estacionários. A seguir, um detector de sequência positiva (PSD) com adaptador de frequência será utilizado nas forças contra-eletromotrizes observadas, possibilitando a obtenção da componente de frequência fundamental e eliminando as componentes harmônicas da FCEM. Uma malha de captura de fase (PLL) realimentada cujo mecanismo de ajuste é um controlador PI será empregada nas componentes de sequência positiva para estimar a posição e velocidade da máquina. Resultados de simulação demonstram que a estimação da posição e velocidade através das componentes de sequência positiva apresenta superioridade quando comparada às grandezas obtidas diretamente pelas forças contra-eletromotrizes reais da máquina.
Impact of Quasi‐Idealized Future Land Cover Scenarios at High Latitudes in Complex Terrain

Afforestation is gaining popularity as a climate mitigation policy in many countries, including high latitude regions such as Norway. However, the impacts of afforestation on local‐to‐regional climate is poorly understood. This study uses the Weather Research and Forecasting model to investigate the biogeophysical impacts of different forestry scenarios on the local‐to‐regional climate of Norway. The forestry scenarios considered are the conversion of open spaces to either evergreen forest by active afforestation or to mixed forest by natural succession. Results show both forestry scenarios lead to additional warming of surface temperatures in winter and spring (between 1.0°C and 1.5°C) and cooling in summer (between −1.6°C and −1.3°C). A temperature decomposition analysis shows that the warming in winter and spring is driven by surface albedo changes while summer cooling is driven by changes in sensible heat fluxes for afforestation and surface albedo for natural succession. Maximum 2 m air temperature increases considerably in spring in both forestry scenarios (∼0.8°C to 1.0°C). Analysis of precipitation, multiple climate indices and extremes, reveal little or no response to the different forestry scenarios. The largest societally relevant response to the forestry scenarios is the partial mitigation of the reduction in snow days expected from global warming by 10–20 days. This suggests that implementing current afforestation policies for climate mitigation in Norway may adversely exacerbate some effects of global warming locally while mitigating others. As such, the impacts of afforestation on the local‐to‐regional climate at high latitudes are complex and cannot support or dismiss afforestation as a climate mitigation policy.
Biocompatiblibility analysis of the decellularized bovine pericardium

The decellularized bovine pericardium and its potential use as a natural scaffold is a promising approach in the field of tissue engineering and regenerative medicine. The reaction of the host toward decellularized scaffolds depends on their biocompatibility, which should be satisfied being before applied in clinical use. Purpose: to evaluate the biocompatibility of the extracellular matrices, which were decellularized by trypsin enzyme and anionic sodium dodecyl sulfate (SDS) detergent. Material and methods. Pericardial sacs were acquired from 12-18 months’ age bulls. Tissue decellularization was performed by using 0.25 % Trypsin solution and 1 % ionic SDS for group I and 0.1 % SDS for group II samples. The implantation was performed on Wistar rats. The tissue samples were stained with hematoxylin & eosin, Congo red and Masson's Trichrome for histological analysis. Results. In group 1 in 3 months after subcutaneous implantation in rats we noticed the inflammation in surrounding tissue and degradation of the implant. Under the same conditions in animals of group 2 implant replacement with growing immature connective tissue was noted. Bio-implant of this group did not degrade, moreover it's integrated to the tissues of experimental rats. Conclusion. Our results showed that decellularized bovine pericardium by 0.1 % SDS can become an alternative material for tissue engineering and has the potential for further use in human surgery.
Thermocapillary motion of a solid cylinder near a liquid–gas interface

The motion of a solid, infinitely long cylinder perpendicular to a convective liquid–gas interface due to thermocapillarity is investigated via an analytical model. If the cylinder temperature differs from the bulk temperature, a temperature gradient exists along the liquid–gas interface. This results in surface tension gradients at the liquid–gas interface, causing fluid flow around the particle, which induces propulsion. For small particles and, thus, small Peclet and Reynolds numbers, the steady-state equations for temperature and flow fields are solved exactly using two-dimensional bipolar cylindrical coordinates. The velocity of the cylinder as a function of separation distance from the liquid–gas interface is determined for the case of a constant temperature or a constant heat flux on the surface of the cylinder. A larger temperature gradient at the liquid–gas interface in the latter system leads to a larger cylinder velocity and a higher propulsion efficiency. The thermocapillary effect results in larger force on a cylinder than forces arising from other self-propulsion mechanisms.
TO MEASURE SATISFACTION OF TOURISTS VISITING THE WORLD HERITAGE SITE OF AJANTA CAVES

To create effective marketing strategies for Heritage Destination in the tourism industry, an in depth knowledge of tourists is crucial. The aim of this study is to measure tourist satisfaction of the highly trafficked destination of the World Heritage Site of Ajanta Caves in Aurangabad (Maharashtra, India). Primary data was collected from 100 tourists (foreign & domestic tourists) visited Ajanta caves in the month of January 2020 using questionnaire. Data Analysis was done by using independent sample t-test and descriptive statistics. The findings of the study suggested that tourists were strongly satisfied with the appealing monument, facilities at the monument, scenic beauty of Ajanta caves and conservation of the monument. On the contrary tourists were let down with the accessibility & connectivity. It was also observed that there is no significant difference between satisfaction of foreign tourists and domestic tourists. Further researcher has come up with the suggestions for the destination planners and promoters to improve tourists footfall at the destination.
Effective Treatment of NSCLC with Surgery After Nivolumab Combined with Chemotherapy: A Case Report and Brief Review of the Literature

Introduction Immuno checkpoint inhibitors (ICIs) including anti-PD-L1 antibody have shown certain therapeutic effects on various cancer types. Here, we reported a case of the patient with resectable non-small cell lung cancer (NSCLC) showing a complete response to nivolumab combined with chemotherapy. Patient Information A 66-year-old male was diagnosed with stage IIIA large cell lung cancer, cT2N2M0, who was considered impossible to have a tumor resection due to his right hilar node enlargement. The diameter of the neoplasms was 22mm, and the patient wanted to get the chance of surgery. Light of all, surgery was the only radical treatment option and therefore planned. Interventions After administering 2 cycles of nivolumab combined with paclitaxel and cisplatin, the second chest computed tomography (CT) after the first scanning revealed the tumor apparent shrinking and vascular compression was disappeared than before. We performed a right upper lobectomy and mediastinal lymph node dissection. Pathologically, we confirmed no large cell lung cancer cells in the resected lung specimen. Outcomes The follow-up showing that patient remains alive without recurrence to these days. Conclusion This case report may provide a clue to the future development of induction therapy using nivolumab and surgery. The combined treatment of nivolumab and chemotherapy is likely to be considered as an optional management of resectable NSCLC.
The Impact of COPD Exacerbations in the Year Following Pulmonary Rehabilitation: Secondary Analysis of a Randomised Controlled Trial

Background Pulmonary rehabilitation is an effective treatment for people with chronic obstructive pulmonary disease (COPD), but its benefits are poorly maintained. The aim of this study was to evaluate the impact of COPD exacerbations in the year following pulmonary rehabilitation on outcomes at 12 months. Methods This was a secondary analysis from a trial of home versus hospital-based rehabilitation in COPD, with 12 months of follow-up. Moderate and severe exacerbations were identified using administrative data (prescriptions) and hospital records (admissions) respectively. The impact of exacerbations at 12 months following pulmonary rehabilitation was evaluated for quality of life (Chronic Respiratory Questionnaire, CRQ), dyspnea (modified Medical Research Council, mMRC), exercise capacity (6-minute walk distance, 6MWD) and objectively measured physical activity (moderate-to-vigorous physical activity, MVPA). Results A total of 166 participants were included, with mean age (SD) 69 (9) years and forced expiratory volume in one second (FEV1) 49 (19)% predicted. Moderate exacerbations occurred in 68% and severe exacerbations in 34% of participants. Experiencing a severe exacerbation was an independent predictor of worse 12-month outcomes for CRQ (total, fatigue and emotional function domains), mMRC, 6MWD and MVPA (all p<0.05). Participants who completed pulmonary rehabilitation were less likely to have a severe exacerbation (29% vs 48%, p=0.02). Severe exacerbations were more likely in those with worse baseline CRQ total (odds ratio 0.97, 95% CI 0.95 to 0.99) and FEV1%predicted (0.98, 95% CI 0.96 to 0.99). Conclusion Severe exacerbations occur frequently following pulmonary rehabilitation and predict worse 12-month outcomes. Strategies to maintain the benefits of pulmonary rehabilitation should address exacerbation prevention and management.
Germination-enhancing and zinc-sparing roles for selenium in broccoli

Large areas of China have soils low in both available selenium (Se) and zinc (Zn). In order to investigate whether Se supplied as either selenate or selenite can increase germination and growth compared with low-Se controls we used broccoli, an important vegetable with anticancer effects, especially when biofortified with Se. Broccoli was grown under both Zn adequacy and Zn deficiency to determine whether interactions between these minerals affect plant growth. Selenite and selenate at a wide range of doses increased the speed and extent of germination. Both inorganic Se forms increased early root and shoot growth at low concentrations, with selenite having a stronger effect than selenate. A sand culture trial showed a similar growth increase due to low-dose Se under Zn deficiency but not under Zn adequacy. Conversely, at high Se levels, the results provided evidence from biomass, water use, photosynthesis and gas exchange that broccoli growth was inhibited at high Se levels, with selenite being more toxic than selenate. In this broccoli trial, the two Se forms were equally effective in increasing leaf Se concentration, whereas in most plants selenite is largely converted to organic Se forms and stored in the roots. This study suggests that Se, supplied either as selenate or selenite, may improve germination and growth in broccoli, especially on Zn-deficient soils. Field trials conducted on soils which are very low in both plant-available Se and Zn are needed.
Effects of fire on ground‐dwelling arthropods in a shrub‐dominated grassland

Abstract Arthropods are abundant and diverse animals in many terrestrial food webs. In western Oklahoma, some shrublands are interspersed with discrete, dense thickets of tall, woody vegetation, known as mottes. Some of these shrublands are managed with prescribed burning. The goal of this study was to examine whether prescribed burning interacted with habitat type (i.e., shrubland versus mottes) to affect ground‐dwelling arthropod communities. Arthropods were collected in pitfall traps at four sampling locations in relation to mottes; in the center of mottes, and three plot location in shrublands; 1 m, 15 m, and 50 m away from the edge of the motte. There were three treatment levels for burning: one year postburn (burned in dormant months of 2017), two years postburn (burned in dormant months of 2016), and unburned (burned in dormant season of 2014 and prior). There were no significant interactions between prescribed burning and habitat type. Mottes had a different community of arthropods compared with the surrounding shrubland. Mottes also had lower overall abundance, but a higher diversity of arthropods. In terms of fires, arthropod communities one year after burning were different from those two or more years after burning. There was no effect of burning on overall arthropod abundance, but plots that were one year since burning had significantly lower diversity compared with plots that were two or more years postburn. The results of this study suggest that both fire and mottes can independently facilitate heterogeneity in arthropod communities, but they do not appear to interact with one another.
Composição centesimal do fruto, extrato concentrado e da farinha da uva-do-japão

Hovenia dulcis, whose popular name is Japanese grape, belongs to the family Rhamnaceae, native of China, Japan and Korea, is widely distributed in southern Brazil. Rich in sugar and with good acceptance for human consumption it can be consumed fresh or processed. There are no literature reports of its use in food products. The aim of this study was to determine the chemical composition of the Japanese grape fruit, concentrated extract and flour. The contents for moisture (54.08, 52.44 e 19.08g 100g-1), ash (2.16, 4.09 e 4.48g 100g-1), protein (3.74, 2.77 e 5.73g 100g-1), ethereal extract (1.42, 0.37 e 1.82g 100g-1), dietary fiber (12.56, 3.33 and 25.62g 100g-1) and total sugars (19.46, 37.34 and 42.53g 100g-1) were obtained for the fruit, concentrated extract and flour, respectively. Quantification by liquid chromatography confirmed that the content of reducing sugars (fructose, 6.15g 100g-1 and glucose, 6.57g 100g-1) is higher than the non-reducing sugars content in fruit (sucrose, 3.56g 100g-1). Calories resulted in values of 105.56, 165.14 and 216.09kcal 100g-1 for fruit, concentrated extract and flour, respectively. The flour is rich in sugars and has a high content of dietary fiber being able to be used as an alternative ingredient in bakery products. Sensory analysis of the concentrated extract revealed an acceptability rate of 82% among the judges, showing good potential for jams' production.
After an initial period of anticoagulation, are IVC filters better than no IVC filters in preventing recurrent pulmonary embolism?

In patients who can be treated with anticoagulation, inferior vena cava (IVC) filters offer little-to-no help in preventing recurrent pulmonary embolism (PE) and may increase the risk of deep vein thrombosis (SOR: B, based on inconsistent randomized controlled trials). Guidelines do not recommend IVC filters for use in patients who are adequately anticoagulated; however, clinicians might consider IVC filters for patients at high-risk for PE when anticoagulants are contraindicated or when a PE occurs in spite of adequate anticoagulation (SOR: C, expert opinion).
