Selenium antimony sulfide (Sb2(S,Se)3) is an attractive photovoltaic absorber material owing to its suitable band gap, large absorption coefficient, and photoelectric properties. Chemical bath–deposited cadmium sulfide (CBD-CdS) is the most widely used buffer layer material for Sb2(S,Se)3...

Quantitative understanding of human movement behaviors would provide helpful insights into the mechanisms of many socioeconomic phenomena. In this paper, we investigate human mobility patterns through analyzing taxi-trace datasets collected from five metropolitan cities in two countries. We...
