Characterization of the Quality Factor in Spiral Coil Designs for High-Frequency Wireless Power Transfer Systems using Machine Learning

This paper presents a machine learning-based char-acterization of the quality (Q) factor in spiral coil designs for wireless power transfer systems operating at MHz frequencies. Due to skin and proximity effects, at such frequencies, it is challenging to estimate the Q factor of the coupling coils, which is a critical parameter to determine the system's efficiency. A three-dimensional (3D) electromagnetic (EM) simulator allows us to precisely analyze the performance of different coil structures. However, the long processing time in the simulator is a bottleneck for quickly optimizing the coil design. To overcome this issue, we here propose a design method with a feed-forward neural network (FNN) to predict the parameters of the spiral coil. The FNN leverages the data set collected via the 3D quasi-static EM field simulator to train a predictor using the stochastic gradient descent algorithm. After optimization, the FNN model estimates the Q factor of the spiral coil without any delay. The proposed algorithm shows an accuracy larger than 96% under an arbitrary structure. Moreover, the proposed coil design method significantly reduces the computation time and hence, the analysis complexity.

Histological Severity of Cirrhosis Influences Surgical Outcomes of Hepatocellular Carcinoma After Curative Hepatectomy

Background Hepatocellular carcinoma (HCC) is frequently associated with cirrhosis. The present study investigated the impact of histological severity of cirrhosis on surgical outcomes for HCC and further developed novel nomograms to predict postoperative recurrence and survival. Methods A total of 1524 consecutive patients undergoing curative hepatectomy for HCC between 1999 and 2015 were retrospectively studied. Cirrhotic severity was histologically staged according to the Laennec staging system. Short- and long-term outcomes were investigated. Recurrence-free survival (RFS) and overall survival (OS) predictive nomograms were constructed based on the results of multivariate analysis. The predictive accuracy of the nomograms was measured by the concordance index (C-index) and calibration. Results Patients in the severe cirrhosis group had significantly higher morbidity and mortality rates than patients in the no, mild, and moderate cirrhosis groups. The 5-year RFS and OS rates were 36.8% and 64.5%, respectively, in the no cirrhosis group, compared to 34.8% and 60.4% in the mild cirrhosis group, 17.3% and 43.4% in the moderate cirrhosis group, and 6.1% and 20.1% in the severe cirrhosis group. Long-term survival outcomes were significantly worse as cirrhotic severity was increased. The C-index was 0.727 for the RFS nomogram and 0.746 for the OS nomogram. Calibration curves showed good agreement between actual observations and nomogram predictions. The 2 nomograms had a superior discriminatory ability to predict RFS and OS compared to other staging systems. Conclusion Histological severity of cirrhosis significantly affected surgical outcomes in HCC patients undergoing curative hepatectomy. The novel nomograms, including histological severity of cirrhosis, showed an accurate prediction of postoperative recurrence and survival.
RANKED RECALL: EFFICIENT CLASSIFICATION BY EFFICIENT LEARNING OF INDICES THAT RANK

Efficient learning and categorization in the face of myriad categories and instances is an important challenge. We investigate algorithms that efficiently learn sparse but accurate category indices. An index is a weighted bipartite graph mapping features to categories. Given an instance, the index retrieves, scores, and ranks a set of candidate categories. The ranking or the scores can then be used for category assignment. We compare index learning against other classification approaches, including one-versus-rest and top-down classification using support vector machines. We find that the indexing approach is highly advantageous in terms of space and time efficiency, at both training and classification times, while retaining competitive accuracy. On problems with hundreds of thousands of instances and thousands of categories, the index is learned in minutes, while other methods can take orders of magnitude longer. Part of this research was performed while the author was at Yahoo! Research.
Examining Skills and Abilities During the Pandemic – Psychology Students’ and Examiners’ Perceptions of a Digital OSCE

Finding valid and reliable ways to assess complex clinical skills within psychology is a challenge. Recently, there have been some examples of applying Objective Structured Clinical Examinations (OSCEs) in psychology for making such assessments. The aim of this study was to examine students’ and examiners’ perceptions of a digital OSCE in psychology regarding quality and students’ feelings about the OSCE. Participants were 51 students enrolled in the Programme for Master of Science in Clinical Psychology during two semesters and nine examiners assessing each OSCE occasion, at Umeå University, Sweden. Web-based questionnaires were used for data collection. Psychometric analyses indicated that the subscales in the student questionnaire had adequate or close to adequate levels of item and scale reliability. Both students and examiners felt that the digital OSCE was realistic, valid and well-aligned with professional practice. Although students perceived the digital OSCE as stressful, the results showed that they were focused and concentrated and found the OSCE to be a positive learning experience, implying that the stress did not affect performance to any significant extent. Based on the examiners’ experiences, it can be concluded that there are both advantages and disadvantages which need to be considered when planning future digital OSCEs.
Working as an ECE Professional During Covid-19 in Austria: Demands and Resources Profiles and Their Relations With Exhaustion and Work Engagement

The current study explores patterns of intraindividual demands and resources of ECE professionals in Austria during covid-19 by adopting a person-centred analytic approach. Latent Profile Analyses reveal three distinct subgroups (high demands/low resources vs. moderate demands/high resources vs. high demands/moderate resources). Results show that individuals assigned to the subgroup, which is characterized by moderate demands and high resources are less exhausted and show higher work engagement, than individuals assigned to the other subgroups. Individuals classified in the high demands and moderate resources are also less exhausted and more engaged than the individuals in the high demands and low resources group.

Unified Approach to Fractional Calculus Images Involving the Pathway Transform of Extended 
 k
 -Gamma Function and Applications

A path way model is concerned with the rules of swapping among different classes of functions. Such model is significant to fit a parametric class of distributions for new data. Based on a such model, the path way or P δ transform is of binomial type and contains a family of different transforms. Taking inspiration from these facts, present research is concerned with the computation of new fractional calculus images involving the extended k -gamma function. The non-integer kinetic equations containing the extended k -gamma function is solved by using pathway transform as well as validated with the earlier obtained results. P δ transform of Dirac delta function is obtained which proved useful to achieve the purpose. As customary, the results for the frequently used Laplace transform can be recovered by taking δ ⟶ 1 in the definition of P δ transform. Important new identities involving the Fox-Wright function are obtained and used to simplify the results. It is remarkable that the several new and novel results involving the classical gamma function became possible by using this approach.
Effectiveness of Chinese Native Culture Education for Improving Undergraduate Nursing Students' Transcultural Self-Efficacy

Aim The aim of this study is to evaluate the impact of Chinese native culture education based on Chinese native culture on the intercultural competence of undergraduate nursing students. Method A quasi-experimental design with pretest and posttest was used. We recruited nursing students from 4 classes of the School of Nursing in our hospital in 2016 as research subjects. Undergraduate nursing students (n = 79) who completed one semester of education in indigenous Chinese culture completed a demographic questionnaire and the transcultural self-efficacy tool (TSET). Chinese native culture education is the topics related to nursing, consistent with the culture of Chinese patients under the background of Chinese native culture, including the dietary habits, taboos, religions, values, particularly Chinese medicine, and specific diseases. The control group (n = 91) was students who did not participate in Chinese native culture education and completed the instrument during the same time frame. Result Students who participated in Chinese native cultural education significantly improved their transcultural self-efficacy in three dimensions: cognition, emotion, and practice. Compared with the control group, the students in the cultural education group had higher change scores in three sizes of transcultural self-efficacy. Conclusion When strengthening cultural education for undergraduate nursing students, adding content related to Chinese native culture can improve their transcultural self-efficacy and meet the growing cultural needs of patients.
Illicit Substance Use and the COVID-19 Pandemic in the United States: A Scoping Review and Characterization of Research Evidence in Unprecedented Times

We carried out a scoping review to characterize the primary quantitative evidence addressing changes in key individual/structural determinants of substance use risks and health outcomes over the first two waves of the COVID-19 pandemic in the United States (US). We systematically queried the LitCovid database for US-only studies without date restrictions (up to 6 August 2021). We extracted quantitative data from articles addressing changes in: (a) illicit substance use frequency/contexts/behaviors, (b) illicit drug market dynamics, (c) access to treatment and harm reduction services, and (d) illicit substance use-related health outcomes/harms. The majority of 37 selected articles were conducted within metropolitan locations and leveraged historical timeseries medical records data. Limited available evidence supported changes in frequency/behaviors/contexts of substance use. Few studies point to increases in fentanyl and reductions in heroin availability. Policy-driven interventions to lower drug use treatment thresholds conferred increased access within localized settings but did not seem to significantly prevent broader disruptions nationwide. Substance use-related emergency medical services’ presentations and fatal overdose data showed a worsening situation. Improved study designs/data sources, backed by enhanced routine monitoring of illicit substance use trends, are needed to characterize substance use-related risks and inform effective responses during public health emergencies.
Age Evolution of Lipid Accretion Rate in Boars Selected for Lean Meat and Duroc Barrows

Simple Summary Fat deposition profile and fatty acid biosynthesis in adipose tissues are two relevant metabolic processes for breeding companies as the fat content of meat relates to its technological, organoleptic, and nutritional quality. Age, breed, and sex have a great impact on fat metabolism. Therefore, in the present experiment, a labeled saturated fatty acid was added to the diet of pigs belonging to three different producing types during two growth phases, to define the rate of its incorporation into body fat. In addition, the activity of the enzyme stearoyl-CoA desaturase, which promotes the conversion of some saturated fatty acids into monounsaturated, was analyzed. In the growing phase, direct incorporation of fat from diet was higher than biosynthesis in most adipose tissues, whereas in the fattening phase it was higher only in the liver, revealing the changing roles of organs in fat metabolism with age. The leaner pigs also obtained a higher fat incorporation, denoting higher reliance on dietary fatty acids for fat deposition; overall, real stearoyl-CoA desaturase activity was higher in the fattening phase. Abstract Fatty acid (FA) deposition in growing–fattening pigs is mainly based on endogenous lipid synthesis, but also direct FA incorporation from the diet. To evaluate the direct fat incorporation rates and the endogenous desaturation action of the stearoyl-CoA desaturase (SCD) enzyme, a deuterium (D)-labeled saturated FA (d35-C18:0) was added to the diet. Sixteen three-way (3W) crossbred boars, and thirty-two purebred Duroc barrows homozygous for the SCD single nucleotide polymorphism rs80912566 (16 CC/16 TT), were used. Half of the animals of each genotype belonged to the growing and fattening phases. The fractional incorporation rate (FIR) of dietary fat in growing pigs was generally higher in adipose tissues, whereas in fattening pigs it was higher in the liver. Duroc pigs exhibited lower FIRs than 3W pigs, suggesting lower rates of endogenous synthesis by 3W pigs. Real fractional unsaturation rates (FURs) increased with age by the higher FIRs in 3W pigs and the de novo synthesis pathway in Duroc genotypes. Moreover, pigs carrying the SCD_T allele showed more enhanced oleic acid biosynthesis than Duroc CC pigs. In conclusion, suitable feeding protocols should be designed for each pig type to optimize production traits, considering that the metabolic pathway of FA for its deposition may differ.
Retinopathy of Prematurity in the University of Calabar Teaching Hospital, Calabar, Nigeria: An Early Report of a Screening Service

Background: Retinopathy of prematurity (ROP) is an important cause of childhood blindness worldwide. This blindness is avoidable through regular screening of preterm infants and prompt intervention for those with the condition. Aims/Objectives: This study aimed to determine the pattern of presentation of ROP and the risk factors for its development among preterm infants in the Neonatal Unit of the University of Calabar Teaching Hospital, Calabar, Nigeria. Design of Study: This study is a prospective, longitudinal study. Settings: The study was carried out in the Special Care Baby Unit, Sick Baby Unit, and Neonatal Clinic of the Department of Paediatrics and Child Health, University of Calabar Teaching Hospital, Calabar, Nigeria. Materials and Methods: All preterm infants whose mothers had given informed consent to participate were enrolled. Ocular examination was performed by a trained ophthalmologist. ROP was staged and documented using the revised version of the International Classification of ROP. Data were entered into a questionnaire and analysed using IBM SPSS version 22. Results: Of the 53 neonates recruited into the study, ROP was detected in 11 (21%) neonates, of which 9 (82%) had stage 1 disease, 2 (18%) had stage 2, and none had stage 3. ROP was more common in females, 7 (63.6%), than their male counterparts 4 (36.4%). ROP was higher among those with gestational age (GA) ≤30 weeks [9 (81.8%)] when compared with those with GA >30 weeks [2 (18.2%)] (P = 0.016). Other risk factors for ROP assessed by this study were found not to be significantly associated with the occurrence of ROP. Conclusion: ROP was present in 21% of the neonates, and the majority had stage 1 disease. This finding emphasizes the need for screening of all preterm neonates for ROP in order to forestall avoidable blindness which could result from this condition.
Association Between Serum Albumin Level and Microvascular Complications of Type 2 Diabetes Mellitus

Objective To analyze the associations between serum albumin (sALB) level and diabetic microvascular complications, including diabetic retinopathy (DR) and diabetic kidney disease (DKD), in patients with type 2 diabetes mellitus (T2DM). Methods This retrospective study included 951 hospitalized patients with T2DM who had completed screening for DR and DKD during hospitalization. Patients were divided into three groups according to sALB tertiles. Multivariate logistic regression analysis was used to assess the association of sALB with microvascular complications. Results The prevalence of DR, DKD and macroalbuminuria increased with decreasing sALB levels. Multivariate logistic regression analysis showed that lower levels of sALB (Q1) were associated with higher risk of DR (odds ratio [OR]: 1.59, 95% confidence interval [CI]: 1.12–2.26), DKD (OR: 3.00, 95% CI: 2.04–4.41) and macroalbuminuria (OR: 9.76, 95% CI: 4.62–20.63) compared with higher levels of sALB (Q3) after adjustment for other risk factors. After stratification by sex and age, the effect of lower levels of sALB (Q1) on DR incidence was more obvious in patients with male (OR: 1.60, 95% CI: 1.00–2.56), and aged<65 years (OR: 1.74, 95% CI: 1.14–2.65) (P < 0.05 for all); the effect of lower levels of sALB (Q1) on the incidence of DKD was significant in both males (OR: 3.78, 95% CI: 2.26–6.32) and females (OR: 2.35, 95% CI: 1.26–4.35) (P < 0.05 for all), while only the age <65 years (OR: 3.46, 95% CI: 2.16–5.53) was significant in the age subgroup (P < 0.001). Conclusion Decreased sALB levels may be an independent risk indicator of DR and DKD in patients with T2DM, and significantly associated with DKD progression. For DR screening, special attention should be paid to men aged <65 years, while screening for DKD should pay attention to people <65 years old.
Computational design of yeast synthetic gene circuits

I this work we firstly proposed lateral-flow assay combined with primer extension (PEXT) and gold nanoparticles to SNP genotyping of tmigd1 gene in Tsaiya duck which has advantages of easy operation, cost effective and time saving. The gold nanoparticles were tailed with thiol-(dT)30 using salt-aging method at 25 oC and used as label of lateral-flow assay. The lateral-flow device is mainly composed of test and control zone on the nitrocellulose membrane containing streptavidin and d(A)30, respectively. When the specific SNP exists, the corresponding primers can be extended, and then the reaction product will be able to be captured by streptavidin in the test zone due to the introduction of biotin-dUTP into the reaction product during PEXT. Gold nanoparticles will hybridize with reaction product to make it become visible. Here we reported the optimized parameters of Mg2+ in PEXT reaction and streptavidin on membranes to detect the signal specificity. In addition, it is found that increasing amount of PCR product and PEXT reaction cycle number result in the increase of the signal intensity without observable change of signal specificity.
Evolution of the Electronic and Optical Properties of Meta-Stable Allotropic Forms of 2D Tellurium for Increasing Number of Layers

In this work, ab initio Density Functional Theory calculations are performed to investigate the evolution of the electronic and optical properties of 2D Tellurium—called Tellurene—for three different allotropic forms (α-, β- and γ-phase), as a function of the number of layers. We estimate the exciton binding energies and radii of the studied systems, using a 2D analytical model. Our results point out that these quantities are strongly dependent on the allotropic form, as well as on the number of layers. Remarkably, we show that the adopted method is suitable for reliably predicting, also in the case of Tellurene, the exciton binding energy, without the need of computationally demanding calculations, possibly suggesting interesting insights into the features of the system. Finally, we inspect the nature of the mechanisms ruling the interaction of neighbouring Tellurium atoms helical chains (characteristic of the bulk and α-phase crystal structures). We show that the interaction between helical chains is strong and cannot be explained by solely considering the van der Waals interaction.
