With the world-wide development of 2019 novel coronavirus, although WHO has officially announced disease as COVID-19, one controversial term - "Chinese Virus" is still being used by a great number people. In meantime, global online media coverage about COVID-19-related racial attacks increases steadily, most which are anti-Chinese or anti-Asian. As this pandemic becomes increasingly severe, more people start to talk it on social platforms such Twitter. When they refer there mainly two ways:...

Abstract Virtual reality (VR) has been proved as a promising tool for industrial design, but the traditional VR interface of first-person perspective (1PP) is not efficient to support assemblability assessment in narrow assembly spaces. In this paper, we proposed multi-perspectives (MPI) which integrates 1PP and third-person (3PP) using handheld world-in-miniature (WIM). The MPI allows users simulate operations natural manner similar 1PP, while providing with an overview status through WIM...

Collins conjecture is examined in the dissociating molecules of ${\mathrm{H}}_{2}$ and ${\mathrm{N}}_{2}$, proportionality between correlation energy entropy exists region close to equilibrium bond length. Similar also kinetic entropy. On other hand, potential difference expands over a larger nuclear distance. The result suggests method estimate from eigenvalue spectrum 2-matrix discussed.
