Abstract: The total ionizing dose analysis of CMOS-based NAND and NOR logic gate is presented. In the normal operating conditions, universal logic gates function as expected. However, exposure to ...

Abstract: The time delay of digital signals propagating through CMOS gates is unavoidably subject to some timing jitter, which imposes a lower limit on circuit jitter performance. Some of the jitter ...

Indirubin is the active ingredient of Danggui Longhui Wan, a mixture of plants that is used in traditional Chinese medicine to treat chronic diseases. Here we identify indirubin and its analogues as ...

Biliverdin IXβ reductase (BVR-B) catalyzes the pyridine nucleotide-dependent production of bilirubin-IXβ, the major heme catabolite during early fetal development. BVR-B displays a preference for ...
