Hybrid Algorithms of Nonexpansive Semigroups for Variational Inequalities

Two hybrid algorithms for the variational inequalities over the common fixed points set of nonexpansive semigroups are presented. Strong convergence results of these two hybrid algorithms have been obtained in Hilbert spaces. The results improve and extend some corresponding results in the literature

Complexing agent study via computational chemistry for environmentally friendly silver electrodeposition and the application of a silver deposit

In this paper, we introduce a new environmentally friendly silver electroplating bath, employing 5,5-dimethylhydantoin (DMH) and nicotinic acid (NA) as complexing agents, based on the prediction of computational chemistry. An excellent silver electrodeposit with properties suitable for application in electronics packaging was obtained from the newly developed silver electroplating bath, and the electroplating bath is simple and stable. Moreover, the silver(i)-complexes in this bath possessed good complex stability. As a consequence, mirror-bright silver electrodeposits on copper substrates with excellent leveling capability, smooth and compact morphologies, high purity and conductivity, as well as excellent welding property could be realized by adopting this unique bath. Based on the performances of the plating bath and silver deposit, the introduced silver plating bath is a promising candidate for silver electrodeposition applied in microelectronics to replace the conventional cyanide silver electroplating baths.

Construction of Life-Cycle Simulation Framework of Chronic Diseases and Their Comorbidities Based on Population Cohort

Life-cycle population follow-up data collection is time-consuming and often takes decades. General cohort data studies collect short-to-medium-term data from populations of different age groups. The purpose of constructing a life-cycle simulation method is to find an efficient and reliable way to achieve the way to characterize life-cycle disease metastasis from these short-to-medium-term data. In this paper, we have presented our effort at construction of a full lifetime population cohort simulation framework. The design aim is to generate a comprehensive understanding of the disease transition for full lifetime when we only have short-or-medium term population cohort data. We have conducted several groups of experiments to show the effectiveness of our method

Bimetallic Cu/Pt Oxygen Reduction Reaction Catalyst for Fuel Cells Cathode Materials

The oxygen reduction reaction (ORR) is a key process for the operation of fuel cells. To accelerate the sluggish kinetics of ORR, a wide range of catalysts have been proposed and tested. In this work, a nano-dispersed copper-impregnated platinum catalyst prepared by electrodeposition of platinum on a poly[Cu(Salen)] template followed by polymer destruction is described. In addition to the high activity of the thus prepared catalyst in the oxygen reduction reaction surpassing that of both polycrystalline platinum catalyst and the commercial carbon-platinum catalyst (“E-TEK”), it showed remarkable tolerance to the presence of methanol in solution

An Examination of the Behavioral Correlates of Subtypes of Nonsocial Play Among Chinese Preschoolers

This study examined via teacher reports the behavioral correlates of different forms of nonsocial play among Chinese preschoolers, as well as potential gender differences in the linkages in a sample of preschoolers (249 boys, 257 girls) from two cities in mainland China. Measurement models estimated with two-group confirmatory factor analyses yielded invariant factor structures for boys and girls for each of the behavioral measures assessed. Results showed that, for boys and girls, solitary-passive play was negatively associated with prosocial behavior, assertiveness, and teacher delights, and positively related to venting, nonconformance, distractible behavior, fearfulness, depression, and automanipulation. Solitary-passive play was also positively correlated with victimization for girls only. Solitary-active play was negatively associated with prosocial behavior, assertiveness, and teacher delights, and positively related to physical aggression, victimization, venting, nonconformance, distractible behavior, fearfulness, depression, and automanipulation for boys and girls. Reticence, for boys and girls, was negatively correlated with prosocial behavior, assertiveness, and teacher delights, as well as positively related to venting, nonconformance, distractible behavior, fearfulness, depression, and automanipulation

Disability-adjusted life years associated with population ageing in China, 1990-2017

Abstract Background The Chinese population has aged significantly in the last few decades. Comprehensive health losses including both fatal and non-fatal health outcomes associated with ageing in China have not been detailed. Methods Based on freely accessible disability adjusted life years (DALYs) estimated by the Global Burden of Diseases (GBD) 2017, we adopted a robust decomposition method that ascribes changes in DALYs in any given country across two time points to changes resulting from three sources: population size, age structure, and age-specific DALYs rate per 100,000 population. Using the method, we calculated DALYs associated with population ageing in China from 1990 to 2017 and examined the counteraction between the effects of DALYs rate change and population ageing. This method extends previous work through attributing the change in DALYs to the three sources. Results Population ageing was associated with 92.8 million DALYs between 1990 and 2017 in China, of which 65.8% (61.1 million) were years of life lost (YLLs). Males had comparatively more DALYs associated with population ageing than females in the study period. The five leading causes of DALYs associated with population ageing between 1990 and 2017 were stroke (23.6 million), chronic obstructive pulmonary disease (COPD) (18.3 million), ischemic heart disease (13.0 million), tracheal, bronchus, and lung cancer (6.1 million) and liver cancer (5.0 million). Between 1990 and 2017, changes in DALYs associated with age-specific DALY rate reductions far exceeded those related to population ageing (− 196.2 million versus 92.8 million); 57.5% (− 112.8 million) of DALYs were caused by decreases in rates attributed to 84 modifiable risk factors. Conclusion Population ageing was associated with growing health loss in China from 1990 to 2017. Despite the recent progress in alleviating health loss associated with population ageing, the government should encourage scientific research on effective and affordable prevention and control strategies and should consider investment in resources to implement strategies nationwide to address the future challenge of population ageing

Template-Free Electrochemical Preparation of Hexagonal CuSn Prism-Structural Electrode for Lithium-Ion Batteries

A hexagonal prism CuSn alloy was prepared at room temperature from 1-ethyl-3-methylimidazolium dicyanamide ([Emim][DCA]) by the direct template-free electrodeposition method with different concentrations of Cu(I) and Sn(II) at a low current density of 0.04 A dm−2. Moreover, the electrodeposition time was also investigated, and the results indicated that the composition of the CuSn alloy became complex and the structure turned unstable with expanding time. The cycling performance of the hexagonal prism-structural CuSn electrode was investigated, with the first discharge capacity of 345 mAh g−1 and a discharge capacity of about 210 mAh g−1 after 10 cycles
