With the goal of making exclusive-OR formulations of switching functions more readily available to designers for implementation in L S I and VLSI technologies, we introduce the concept of an exclusive-OR space in which an exclusive-OR normal form is deJined to correspond to the conventional disjunctive normal form. A geometrical representation of(More)
Postoperative chylous ascites is a rare complication of aortic aneurysmectomy. Although increasing numbers of abdominal aortic aneurysms are being resected annually, there have been only eight previously reported cases of chylous ascites after this operation. This article describes the ninth case of postoperative chylous ascites after abdominal aortic(More)
After a discussion of the reasons for choosing to implement logic in array form. a detailed description of the nature of array logic is given. Topics specifically discussed include general array structures and implementation, influence of decoder partitioning, design of logic arrays, output phase, " split " variables, feedback in logic arrays, and(More)
Compression of the left renal vein (LRV) between the superior mesenteric artery and the aorta has been termed the nutcracker syndrome. Although often asymptomatic, this syndrome may result in varicocele, ovarian vein syndrome, and rarely LRV hypertension, pelviureteral varices, hematuria, and flank pain. Previous surgical approaches have included(More)
Several electrooptic digital light deflection techniques have been proposed. The maximum number of resolvable deflection positions for all methods is determined, essentially, by economic reasons, the tolerable amount of background light, and aberrations. In this paper, three different types of deflection methods (split angle, total internal reflection,(More)
The spontaneous expulsion of lipoma per rectum is an extremely rare phenomenon. The present case report describes this event in a patient with lower abdominal pain and bleeding per rectum leading to exploratory laparotomy. At surgery, a large intussuscepting ulcerated submucosal lipoma remnant was identified in the transverse colon. This unusual(More)
Percutaneous transluminal laser angioplasty is a new method for treating atherosclerotic disease previously not amenable to routine percutaneous transluminal angioplasty techniques. Our results compared favorably with other clinical trials. Patient selection criteria include lesions in the superficial femoral or popliteal system not capable of being treated(More)
