A CMOS Wideband Linear Current Attenuator with Electronically Variable Gain [PDF]
, 1993 A CMOS highly linear current attenuator is described. The circuit is suited for both differential and single input currents. The current gain is electronically variable between -1 and +1 by means of two controlling currents.

Attenuation by Targeting the B- and T-Cell Attenuator [PDF]
Transplantation, 2011 BTLA is a member of the immunoglobulin family thought to serve as a negative costimulatory molecule on activated T cells. Several recent studies, including the one published in this issue by del Rio and colleagues, have used BTLA-deficient mice and/or anti-BTLA antibodies to investigate the role of BTLA in regulating graft versus host reaction (GvHR ...

Superior Resilience of Non-Gaussian Entanglement against Local Gaussian Noises
Entropy, 2022 Entanglement distribution task encounters a problem of how the initial entangled state should be prepared in order to remain entangled the longest possible time when subjected to local noises. In the realm of continuous-variable states and local Gaussian
