Intrinsic Immune Mechanisms Restricting Human Cytomegalovirus Replication
Viruses, 2021 Cellular restriction factors (RFs) act as important constitutive innate immune barriers against viruses. In 2006, the promyelocytic leukemia protein was described as the first RF against human cytomegalovirus (HCMV) infection which is antagonized by the ...

Transmission and group delay of microring coupled-resonator optical waveguides [PDF]
, 2006 We measured the transmission and group delay of microring coupled-resonator optical waveguides (CROWs). The CROWs consisted of 12 weakly coupled, microring resonators fabricated in optical polymers (PMMA on Cytop).
