Bidirectional flow of two-dimensional dusty plasma under asymmetric periodic substrates driven by unbiased external excitations

Collective transport properties of a one-dimensional (1D) asymmetric periodic substrate modulated two-dimensional (2D) dusty plasma driven by an unbiased sinusoidal excitation force are investigated using Langevin dynamical simulations.It is discovered that by changing the amplitude and frequency of the unbiased sinusoidal external excitations, as

Sequence determinants of human-cell entry identified in ACE2-independent bat sarbecoviruses: A combined laboratory and computational network science approach

Summary: Background: The sarbecovirus subgenus of betacoronaviruses is widely distributed throughout bats and other mammals globally and includes human pathogens, SARS-CoV and SARS-CoV-2.The most studied sarbecoviruses use the host protein, ACE2, to infect cells.Curiously, the majority of sarbecoviruses identified to date do not use ACE2 and cannot
