The reverse stop-signal model for CTLA4 function

Cytotoxic T-lymphocyte antigen 4 (CTLA4) is a co-receptor expressed by activated, memory T cells and regulatory T cells 1,2,3,4,5,6. It is a homodimer that can bind to the homodimeric ligands CD80 ...

2-D Hydrodynamic Simulation of TeraFETs Beyond the Gradual-Channel Approximation for Transient, Large-Signal, or Ultrahigh-Frequency Simulations

Abstract: In the past decade, detection of THz radiation by plasma-wave-assisted mixing in antenna-coupled field-effect transistors (TeraFETs)—implemented in various semiconductor material systems (Si ...
