Nonplanar Overlapped Inductors Applied to Domestic Induction Heating Appliances

Domestic induction heating appliances are evolving from surfaces with three to five fixed cooking areas to flexible cooking zones. These are able to adapt to a number of vessels of any size and shape by using multiple coils. Some state-of-the-art induction systems make use of overlapped inductors in two layers, which combine the high efficiency of large inductors with the high flexibility of small adjacent coils. The main drawback of this concept is the unequal distance between different coils and the vessel, which implies that each coil presents a different impedance depending on its layer. This paper presents an induction system conformed by nonplanar inductors. These inductors are designed in such a way that they can be assembled in overlapping structures, while preserving equivalence among them, i.e., they all present the same impedance. This paper includes the finite-element method modeling of the nonplanar coil, an analysis on the an experimental verification.
Over-Triage in Casevac Categorisation is Common in Hong Kong

Objective To review the categorisation of patients who were transferred out from out-lying islands to urban hospitals utilising casualty evacuation (CASEVAC), and to search for possible patient characteristics which might have contributed to mis-categorisation during the ‘non-flying’ hours. Methods The medical records of 459 patients, who were transferred out in the year 2009 were reviewed. Correctness of categorisation was determined by 2 independent assessors according to the CASEVAC guidelines. The rates of mis-categorisation between ‘clinic hours’ and ‘AED hours’, and that between the ‘flying’ and ‘non-flying’ hours, were compared. The patients' demographic data and their presenting symptoms were collected and analysed using logistic regression models to identify factors contributing to mis-categorisation. Results The mis-categorisation rate was 60.1%. Among them, all were over-categorised. The over-categorisation rates between ‘clinic hours’ and ‘AED hours’, and between ‘flying’ and ‘non-flying’ hours, were not significantly different (p=0.07 and 0.09, respectively). Abnormal pulse rate was significantly associated with over-categorisation (p<0.01). Patients at extremes of age and psychiatric/drunk patients were significantly less likely to be over-categorised (p<0.05 and p<0.01, respectively). There was 20% disagreement between the two assessors when applying the existing CASEVACs guidelines (kappa score 0.58 or ‘moderate agreement’). Conclusions Over-triage in CASEVAC categorisation is common irrespective of the time of day. Revision of the current CASEVAC guidelines is recommended. (Hong Kong j.emerg.med. 2013; 20:327-336)
Synthesis of Tungsten carbide nanoparticles in different dielectric through µ-EDM

ABSTRACT This article focuses on the morphology, shape, and size of NPs which are crucial steps in nanotechnology. The production of tungsten carbide (WC) nanoparticles and tool wear rate under different voltage and duty factors have been studied in two different dielectrics, i.e., EDM oil and kerosene. It has been seen that the generation of NPs and tool wear rate increases with an increase in voltage at a constant duty factor. The maximum amount of generated NPs was obtained at a duty factor of 20%, and voltage 40 V are 0.1013 gm and 0.0447 gm in EDM oil and kerosene, respectively. The higher value of tool wear rate was observed at duty factor 20%, and voltage 40 V are 0.000278 gm/min and 0.000192 gm/min in EDM oil and kerosene, respectively. The production of NPs is more, and the formation of carbide is less with using EDM oil as compared to kerosene. Field emission scanning electron microscopy (FESEM) image depicts that tungsten carbide nanoparticles are spherical, and carbon is in uneven shapes. Energy-dispersive X-ray spectroscopy (EDX) results reveal that the produced nanoparticles contain tungsten (W), Carbon (C), and Oxygen (O) in both dielectrics.
Lossless, broadband monolithic microwave active inductors

Lossless, broadband microwave active inductors are proposed for general-purpose use in microwave circuits. These active inductors operate in a wide frequency range with very low series resistance. They are composed of a common-source cascode FET and a feedback FET which is a common-gate FET or a common-gate cascode FET. The loss can be less than 1/8 the loss of the previously proposed active inductor. The inductance value can be controlled by the external control voltage. The configuration and performance of these devices are described. <<ETX>>
Graph Neural Networks Extract High-Resolution Cultivated Land Maps From Sentinel-2 Image Series

Maintaining farm sustainability through optimizing the agricultural management practices helps build more planet-friendly environment. The emerging satellite missions can acquire multispectral and hyperspectral imagery which captures more detailed spectral information concerning the scanned area, hence allows us to benefit from subtle spectral features during the analysis process in agricultural applications. We introduce an approach for extracting 2.5-m cultivated land maps from 10-m Sentinel-2 (S-2) multispectral image (MSI) series which benefits from a compact graph convolutional neural network. The experiments indicate that our models not only outperform classical and deep machine learning techniques through delivering higher quality segmentation maps, but also dramatically reduce the memory footprint when compared to U-Nets (almost 8k trainable parameters of our models, with up to 31-M parameters of U-Nets). Such memory frugality is pivotal in the missions which allow us to uplink a model to the artificial intelligence (AI)-powered satellite once it is in orbit, as sending large nets is impossible due to the time constraints.
Risk and protective factors for posttraumatic stress and posttraumatic growth in parents of children with intellectual and developmental disorders

ABSTRACT Background: Parents of children with intellectual and developmental disorders often experience potentially traumatic events while caring for their children. Heightened posttraumatic stress (PTS) and posttraumatic growth (PTG) have been found in this population. Objective: We aimed to explore risk and protective factors for their PTS and PTG. Method: A cross-sectional study was conducted with 385 parents (average age M = 43.14 years, SD = 7.40; 95.3% mothers). Results: Parenting trauma showed an adverse effect on developing PTS (beta = 0.25, p < .01) and a positive role in promoting PTG (beta = 0.16, p < .01). Social support was protective in its correlation with lower levels of PTS (beta = −0.12, p < .01) and higher levels of PTG (beta = 0.22, p < .01). Barriers to care were associated with increased PTS (beta = 0.23, p < .01), but unrelated to PTG (beta = .01, p = .855). Negative parenting showed a significant, but small, correlation with more severe PTS (beta = 0.11, p < .05), and was unrelated to PTG (beta = −0.09, p = .065). Conclusions: Our study increases the understanding of posttraumatic reactions in parents, predominantly mothers, of children with IDD and identified parenting-related trauma, social support, and barriers to mental health care as predictive factors of the reactions. More research is needed to confirm and validate the effects of the discussed factors. Although causation can not be inferred, prompt and adequate screening and therapeutic resources should be provided to those mothers who were exposed to multiple stressful caregiving events and had limited healthcare access and less support from their spouses, peers, and caregiving partners. HIGHLIGHTS Parents of a child with Intellectual and Developmental Disorders with parenting trauma had higher posttraumatic stress (PTS) and posttraumatic growth (PTG). Social support was related to lower PTS and higher PTG. Barriers to care were related to higher PTS but unrelated to PTG.
Cytoplasmically localized tRNA-derived fragments inhibit translation in Drosophila S2 cells

Transfer ribonucleic acids (tRNAs) serve not only as amino acid carriers during translation but also as a template for the biogenesis of short fragments that can regulate gene expression. Despite recent progress in the function of tRNA-derived fragments (tRFs), their intracellular localization, protein partners, and role in regulating translation are not well understood. We used synthetic tRFs to investigate their localization and function in Drosophila S2 cells. Under our experimental setting, all synthetic tRFs tested were localized at distinct sites within the cytoplasm in a similar manner in Drosophila S2 cells. Cytoplasmically-localized tRFs were positioned in close proximity to GW182 and XRN1 proteins. Functionally, tRFs, which slightly suppressed proliferation in S2 cells, inhibited translation without any major shift in the polysome profile. These results suggest that 5′-tRFs are cytoplasmically-localized and regulate gene expression through inhibition of translation in Drosophila.
Uniform Rate Setting and the Deposit Channel

Banks do not completely pass-through changes in short-term market rates to depositors. The deposit channel of monetary policy proposes that banks choose the rate of pass-through across their branches based on local deposit market concentration, which consequently affects bank deposit and loan growth. We document the widespread use of uniform deposit rate setting policies by US commercial banks and the nearly universal use of these policies by the largest banks. By definition, uniform rate setting policies ignore local market concentration and therefore the deposit channel cannot operate in these branches. We demonstrate that the early empirical evidence supporting the deposit channel requires excluding branches that are part of centralized rate setting networks, representing 85% of all commercial bank branches. Consistent with varying local demand conditions causing the empirical relationships in branchlevel deposit growth predicted by the deposit channel, we find that these empirical relationships are equally reliable in the set of "rate network" branches as in the full sample of branches, despite the deposit channel being inoperable among network branches. Additionally, we show that several reliable relationships in the cross section of banks do not aggregate because of the extreme bank size distribution and the differential behavior of small and large banks. *We thank Darrell Duffie, Robin Greenwood, Mark Egan, Stefan Nagel, Amit Seru, Jonathan Wallen for helpful comments and discussions. †Begenau: Stanford GSB and NBER and CEPR.

Modeling and simulation of electro-hydraulic telescopic elevator system controlled by programmable logic controller

Traditional hydraulic cylinders are widely used in industry as load lifting tools. There is difficulty in employing these cylinders in narrow installation space like building elevators as well as they require a long working stroke, so solving this problem requires using the telescopic hydraulic cylinder instead. This cylinder is a unique hydraulic cylinder design that uses a sequence of decreasing diameters to create a long operating stroke in a compact-retracted form. In this work, the Auto Station software is used to build a telescopic hydraulic cylinder model that includes hydraulic elements such as double-acting hydraulic telescopic cylinders, pump, valves, pipeline, and filter, as well as electrical parts such as programmable logic controller (PLC), push-bottoms, and position sensors. The proposed model is operated by a PLC controller and has three floors with an overall height of around 300 cm for lifting a 100 kg payload. The accuracy and validity of this model in lifting big weights were demonstrated by the analytical findings of characteristic curves for cylinder position and velocity. This model can be used a basic reference to analyze and construct hydraulic cylinders with any number of stages. The findings of simulations reveal that a quick change in pressure due to phase change causes multi-phase vibration.
Implementation of online classes during national school closure due to COVID‐19 and mental health symptoms of adolescents: A cross‐sectional survey of 5000 students

Abstract Aim Online classes were implemented in numerous schools during the school closure due to COVID‐19. The present study examined the relationship between online classes during national school closure and mental health symptoms after the reopening of schools. Methods We conducted a cross‐sectional survey from October 1 to November 7, 2020 using an anonymous self‐reported questionnaire to evaluate 21 junior and senior high schools in the Saitama prefecture of Japan. Out of the 5538 students who were recruited, 5000 agreed to participate. The relationship between the implementation of online classes and mental health symptoms (emotional symptoms, psychotic experience [PE], and smartphone addiction) was evaluated using mixed‐effect logistic regression models, while controlling for individual and class‐level covariates (e.g., gender, grades). Results Implementation of online classes was reported by 78.2% of classroom teachers, and it was associated with lower rates of emotional symptoms (OR = 0.79, 95% CI = 0.63–0.99, p = 0.040) and smartphone addiction (OR = 0.79, 95% CI = 0.65–0.96, p = 0.020), but not related to PE (OR = 0.91, 95% CI = 0.61–1.36, p = 0.637). Conclusions Implementing online classes during the national school closure might have had a potential protective effect for adolescents' mental health symptoms (especially emotional symptoms and smartphone addiction) after the reopening of schools during the ongoing COVID‐19 pandemic.
How can we Make you Stay? Identifying Motivating Factors to Volunteer Retention in Non-Profit Organizations

Many non-profit organizations depend on volunteers to provide services to their clients thus helping to alleviate some of the costs and financial burdens non-profits face. A volunteer’s motivation and satisfaction drivers are varied thus making the task of attracting and retaining volunteers a difficult one. Since volunteers are a vital part of any non-profit and volunteer supported organization, retention initiatives are crucial to the organization’s success. The aim of this study is to examine the impact of organizational support, group integration, empowerment and participation efficacy on volunteer satisfaction and retention. Over 100 volunteers, from a Central Florida organization, were surveyed to: 1) measure their motivating factors and satisfaction with various aspects of their volunteer experience and 2) measure their intentions to remain as a volunteer. The results of the hierarchical multiple regression suggest that participation efficacy and organizational support are significant predictors to intent to remain with the organization.
Frailty and Aging in HIV— Status Post 13 Years of National Awareness

The People aged 50 years and above comprise over 50% of people living with HIV (PLWH) in the US. Despite the advances made with antiretroviral therapy in increasing their life span, PLWH are plagued with non-AIDS associated conditions which increase their risk for morbidity and mortality. Frailty, a decline in physical and functional reserve, is one of the manifestations of aging, has a prevalence of 5–30%, and occurs up to 2 decades earlier in people aging with HIV (PAWH). The majority of providers for PAWH have minimal experience with the concept of gerontology, frailty, and aging. Hence, there is a gap in clinicians’ knowledge on how to address frailty and aging in PAWH. This review will focus on the clinical interventions that mitigate frailty and aging in PAWH as well as highlight areas of investigation towards achieving these mediations. Beyond the identification of the roles of exercise and nutrition, more studies are needed on the pragmatic approach to apply these resources to routine care. There should be continued reinforcement of the proven strategy of combination antiretroviral therapy as well as treatment of co-infections and age-appropriate health and cancer screening in PAWH.
ARL4C Regulates the Progression of Clear Cell Renal Cell Carcinoma by Affecting the Wnt/β-Catenin Signaling Pathway

Purpose To investigate the expression of the ADP-ribosylation factor (ARF)-like proteins (ARLs) and ARL4C in clear cell renal cell carcinoma (ccRCC) based on bioinformatics analysis and experimentally determine the effect and mechanism of ARL4C on cellular properties involved in ccRCC progression. Methods After downloading the data of cancer patients from the TCGA database, we used various bioinformatics analysis websites and methods to analyze the expression and function of ARLs and ARL4C. The differential expression of ARL4C in clinical renal cancer tissues versus adjacent normal tissues was further verified using immunohistochemistry and real-time quantitative reverse-transcription (qRT-PCR). qRT-PCR was used to explore the expression of ARL4C mRNA in normal renal cells versus different ccRCC cell lines, and the protein expression of ARL4C was further verified using western blotting. CCK-8, colony formation, and EdU assays were used to determine the effect of ARL4C knockdown on ccRCC cell proliferation. We also used wound healing and Transwell assays to analyze the changes in ccRCC cell migration and invasion following ARL4C knockdown. Finally, we used western blotting to probe the molecular mode of action of ARL4C in ccRCC cells after exposure to Wnt signaling pathway agonists. Results Biological function analysis showed that methylation of ARL4C and changes in immune cell infiltration and targeted drug sensitivity caused by altered ARL4C expression affected the prognosis of ccRCC. Further bioinformatics analysis suggested that the expression of ARL4C mRNA was increased in ccRCC, and this was associated with a poor prognosis in ccRCC patients. Increased expression of ARL4C was further verified using qRT-PCR and western blotting of human ccRCC tissue samples. Downregulation of ARL4C significantly inhibited the proliferation, migration, and invasion of ccRCC cells, and activation of the Wnt/β-catenin pathway promoted the expression of ARL4C. As an essential downstream effector of the Wnt signaling pathway, ARL4C increased the expression of cyclin D1 and c-myc, thereby increasing the ability of the cells to undergo epithelial-mesenchymal transition (EMT) and ccRCC progression. Conclusions As a critical factor in the Wnt/β-catenin pathway, ARL4C regulates EMT and progression in ccRCC.
Contrast-Enhanced Computed Tomography–Based Radiogenomics Analysis for Predicting Prognosis in Gastric Cancer

Objective The aim of this study is to identify prognostic imaging biomarkers and create a radiogenomics nomogram to predict overall survival (OS) in gastric cancer (GC). Material RNA sequencing data from 407 patients with GC and contrast-enhanced computed tomography (CECT) imaging data from 46 patients obtained from The Cancer Genome Atlas (TCGA) and The Cancer Imaging Archive (TCIA) were utilized to identify radiogenomics biomarkers. A total of 392 patients with CECT images from the Nanfang Hospital database were obtained to create and validate a radiogenomics nomogram based on the biomarkers. Methods The prognostic imaging features that correlated with the prognostic gene modules (selected by weighted gene coexpression network analysis) were identified as imaging biomarkers. A nomogram that integrated the radiomics score and clinicopathological factors was created and validated in the Nanfang Hospital database. Nomogram discrimination, calibration, and clinical usefulness were evaluated. Results Three prognostic imaging biomarkers were identified and had a strong correlation with four prognostic gene modules (P < 0.05, FDR < 0.05). The radiogenomics nomogram (AUC = 0.838) resulted in better performance of the survival prediction than that of the TNM staging system (AUC = 0.765, P = 0.011; Delong et al.). In addition, the radiogenomics nomogram exhibited good discrimination, calibration, and clinical usefulness in both the training and validation cohorts. Conclusions The novel prognostic radiogenomics nomogram that was constructed achieved excellent correlation with prognosis in both the training and validation cohort of Nanfang Hospital patients with GC. It is anticipated that this work may assist in clinical preferential treatment decisions and promote the process of precision theranostics in the future.
Effects of β-glucan from S. cerevisiae on the expression of Casp9, Ccna2 and Sod1 genes in MCF-7 cells

β-Glucans (βG) are polysaccharides widely distributed in nature with chemopreventive properties. The aim of this study was to investigate the effects of βG and the combined treatment with doxorubicin (Dox) on cell viability and mRNA levels of genes involved in cell cycle, apoptosis and antioxidant response. βG was not cytotoxic. The mRNA levels of CCNA2 of cells exposed to β-glucan was upregulated and the exposure to Dox decreased the expression, while the combination led to an upregulation. Modulation of mRNA levels of CASP9 suggest that βG could inhibit promotion and progression steps of carcinogenesis, eliminating neoplastic cells. The upregulation of CCNA2 gene in combined treatment could be occurred due to ability of βG in restoring the cell cycle distribution pattern after treatment with Dox. The upregulation of SOD1 suggests that βG can enhance the intracellular antioxidant defense, reducing the levels of superoxide dismutase induced by Dox. This response could reduce oxidative damage and attenuate tissue damage during chemotherapeutic treatment. Our data suggest that the drug combination may be less effective in killing tumor cells than the treatment with Dox alone. Thus, future studies should carefully consider this effect on indication of βG during chemotherapy
