Digitally controlled pulse-level discriminator operates over wide voltage range

Low power drain discriminator circuit generates an output pulse when an input pulse exceeds a discrete digitally controlled threshold voltage. The discriminator operates over a wide linear or nonlinear range of threshold levels. It uses several amplifier stages ahead of a fixed-reference threshold detector

Switching circuits with fast response and low power drain

New logic circuits have response times no longer than 10 nanoseconds and drain only milliwatts of power. The family includes AND and NAND gates and forms the basis of all logic functions. The basic circuits are used in various types of digital-data-processing systems

Passive synchronized spike generator with high input impedance and low output impedance and capacitor power supply Patent

Pulse generator for synchronizing or resetting electronic signals without requiring separate external sourc

Synchronized pulse generator needs no external power

Simple circuit with high input and low output impedance generates a fast rise-time pulse synchronized with an input pulse of slower rise and fall times. Circuit requires no external power

Caught Off Center: Rethinking the Requirements for Antibody Affinity Maturation

Antibody affinity maturation involves selective survival of high affinity B cells and is thought to require the germinal center (GC) microenvironment. In this issue of Immunity, Di Niro et al. (2015) challenge this view, showing that low affinity B cells initiate Salmonella responses and affinity mature outside of GCs

Unraveling the Warp and Weft of B Cell Fate

Two recent Immunity articles (Enzler et al., 2006; Sasaki et al., 2006) probe the roles of Nuclear Factor κ-B (NF-κB) pathways in survival and differentiation mediated by B cell activation factor of the TNF family (BAFF)
