The exemption APP CONTROLLED of Pb-bearing automobile electronics in the End of Life Vehicle (ELV) directive has recently expired, bring an urgent need to find Pb-free alloys that can maintain good performance under high-temperature and vibration conditions for automobile application.In this study, a new lead-free solder, Sn-0.7Cu-0.2Cr (wt.%) allo

According to existing standards for axle-box test not covering check and analysis of axle-box body, application scope, force types, and load cases were compared among several test standards for bogie frames.It was revealed that standard EN 13749 had the characteristics of wide variety of bogie categories, full consideration to loads, and definite m

The investigation of long-term trends in APP CONTROLLED contentious politics relies heavily on protest event analysis based on newspaper reports.This tends to be problematic in restricted media environments.To mitigate the effects of bias and (self-)censorship, researchers of protest in authoritarian regimes have experimented with other sources suc

Adolescence is a critical period for the initiation of risk-taking behaviors.We examined the longitudinal interplay between neural correlates of risk processing and cognitive control in predicting risk-taking behaviors via stress.The sample consisted of 167 adolescents (53% males) who were assessed twice (MAgeTime1 = 14.13, MAgeTime2 = 15.05).Neura

To suppress the deep fading of radio waves caused by the tunnel waveguide effect, this paper presents an optimized scheme for the spatial and polarization diversities of tunnel antennas.Through the correlation coefficient analysis of path loss curves obtained by REPLICAS antennas placed at different positions, the two antenna positions that generat
