Article Synopsis
  • Geophysical mass flows in mountain regions pose risks to health and safety, but the dynamics of granular flow, especially involving different grain types, remain poorly understood.
  • This study examined how small spherical grains, such as glass beads, affect the movement of larger stones in mixed granular flows made up of materials like quartz gravel and angular stone.
  • Findings showed that while small spherical grains generally decrease certain deposition distances for larger stones, they also increase the likelihood of extreme motion, suggesting a complex interaction that enhances mobility in granular mixtures.

The genomes of different human beings are similar. There are only a relatively small number of genetic differences between people. The genetic differences between people are very worthy of study.

Incident angle of saltating particles plays a very important role in aeolian events. In this paper, the incident angles of sand particles near the sand bed were measured in wind tunnel. It reveals that the incident angles range widely from 0° to 180° and thereby the means of angles are larger than published data.

Micro RNAs are small, non-coding RNA molecules that regulate gene expression via either translational inhibition or mRNA degredation. Enhancer of zeste homolog 2 (EZH2)-mediated hypertrophic signaling is a major regulatory response to hypertrophic stimuli. In this study, we constructed AAC rat models and PE-induced hypertrophic cardiomyocytes.

Background: Sexual and reproductive health among adolescents have become increasingly important and aroused international concerns. In this study, we investigate sexual knowledge, attitudes, sexual behaviors, the unwanted pregnancy and the abortion rate and to explore related determinants among college students in Beijing.

Methods: This study is based on a cross-sectional survey of college students' knowledge, attitudes and behavior.
