Layered polytetrafluoroethylene (PTFE) films of large area, composed a porous PTFE core and two compact cover layers, which are commercially available, were internally charged by application corona discharge. The internal charges, probably reside on the inner surfaces make piezoelectric. Initial quasi-static piezoelectric d33 coefficients in range 1000‐2700pCN −1 . After 1500min annealing treatment at temperatures 90 ◦ C, 120 C 150 stabilize typically reach about 75%, 40% 25% their initial...
Low cost, large area, lightweight, stretchable piezoelectric films, based on space-charge electret with a foam structure (i.e., ferroelectrets or piezoelectrets), have been fabricated by using commercially available irradiation cross-linked poly(propylene) (IXPP) sheets. Piezoelectric d33 coefficients are as high 100 pC · N−1. The performance in such IXPP films is well preserved for repeated strains of less than 10%. frequency independent the range from 2 to Hz. Such new class materials may...
Using premier Language Environment Analysis technology to measure and analyze the home language environment, this observational study aims describe environment child ability, drawing on empirical data from 77 households with children aged 18-24 months rural China. The results show large variation in measures of early similar other Chinese samples. Results also demonstrate significant correlations between age maternal employment father's educational attainment adult-child conversations...
This study aims to identify the associations between teacher mental health and student health. Cross-sectional data were collected from 127,877 students aged 9–20 years 2,759 teachers across 31 provinces in China. The of assessed by well-being (life satisfaction positive health), psychological distress (depression anxiety). Controlling for demographic variables, multilevel regression analyses suggest that higher was linked lower depression; depression correlated with life anxiety not any...
Abstract Background A rich language environment is an important element of a nurturing home environment. Despite their proven importance, vocabulary and conversation have been shown to vary widely across households—even within the same socio-economic class. One significant gap in existing literature its nearly exclusive geographic focus on Western developed settings, with little attention given poorer communities lower/middle income countries. The purpose this study was empirically...
Excitonic intraband absorption is used to probe excitonic dynamics in monolayer transition metal dichalcogenides.
In response to the COVID-19 epidemic, many education systems have relied on distance learning and educational technologies an unprecedented degree. However, rigorous empirical research impacts under these conditions is still scarce. We present first large-scale, quantitative evidence detailing how school closures affected in China. The data set includes households teachers of 4,360 rural urban primary students. find that although majority students engaged education, encountered difficulties...
Purpose: This mixed-methods study examined how differences in parental time, knowledge, and economic constraints, as well community socioeconomic contexts, may contribute to home language environment child ability outcomes between peri-urban rural households China. Method: We conducted an explanatory sequential analysis using data from 158 children aged 18–24 months among with low status (SES) southwestern Audio recordings were collected each household analyzed the Language ENvironment...
Objective. The aims of this study were to examine the effects prophylactic heparin treatment during taurocholate-induced pancreatitis in rats and its impact on serum VEGF levels local contents within pancreas. Methods. Severe acute (SAP) was induced by injecting 4% sodium taurocholate into pancreatic duct. Heparin at a dose 150 IU/kg s.c. administered 30 min before operation. sacrificed 1 h, 3 6 h 12 (n = 5 per time point) after onset pancreatitis. severity pancreatitis, evaluated with...
Abstract In low‐ and middle‐income countries, urbanization has spurred the expansion of peri‐urban communities, or urban communities formerly rural residents with low socioeconomic status. The growth these offers researchers an opportunity to measure associations between level home language environment (HLE) among otherwise similar populations. Data were collected in 2019 using Language Environment Analysis observational assessment technology from 158 households Han Chinese children (92...

Research suggests that elements of the family environment may have significant associations with cognitive and language development outcomes. Less is known, however, about in peri-urban China, where rates delay children aged 0-3 years are as high 51% 54%, respectively. Using data collected from 81 households toddlers 18-24 months Southwestern this study examines between stimulating parenting practices, home environment, parental self-efficacy, development. The results indicate practices was...
The Eddy Dissipation Concept (EDC), as a promising flame prediction model, is reviewed comprehensively. Instead of strong modifications the standard EDC constants to fit experiments, modification method based on fuel jet Reynolds number presented in this work and used predict simple nonpremixed syngas Sandia Flame CHN-B piloted CH4/air partially premixed D. Compared with predictions show two flames are properly reproduced modified constants. Some over-predictions might be attributed...
The objective of the current study is to examine impact an in-school computer-assisted learning (CAL) intervention on math achievement rural students in Taiwan, including a marginalized subgroup called Xinzhumin, and factors associated with this impact. In order achieve this, we conducted cluster randomized controlled trial involving 1,840 fourth- fifth-grade at 95 schools four relatively poor counties municipalities Taiwan during spring semester 2019. While Intention-To-Treat (ITT) analysis...
