A case of autoimmune hemolytic anemia (AIHA) in a young child is described. The hemolysis was resistant to steroid therapy but responded to splenectomy and intravenous immunoglobulin. The autoantibody was shown to be anti-Sc1 by both serologic and immunoblotting techniques. This seems to be the first report of an autoanti-Sc1 detected by immunoblotting and the first example of AIHA in a child caused by autoanti-Sc1.
As device technologies are shrinking, developing new techniques for fault isolation and defect localization is becoming a crucial challenge. In this paper, we have shown that by using memory and logic BIST diagnostic techniques, we are able to isolate the defect to two suspected nets. Thirdparty electronic design automation (EDA) tools were used for both MBIST and LBIST hardware implementation and for running diagnostics on the failing part. Using experienced and sophisticated failure analysis support, we were able to confirm with confidence that the stuck-at zero type of defect was caused by a signal line short at metal-5 to the ground line at metal-6.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
