A computer program for routing interconnections on a two-sided printed circuit board with a regular pattern of lines, pins (terminals), and vias (feed-through holes) is described. In this program, each interconnection is given a planned routing—typically, down from the upper pin, through a via, and horizontally to the lower pin. From the top, a(More)
Our studies show that the induction of a chronic inflammatory lesion in the left hind legs of mice by administration of 5000 rad produced distinct abnormalities of the hematopoietic system. A peripheral neutrophilia accompanied reduced numbers of total nucleated cells, stem cells, stromal cells, erythroblasts, and lymphocytes in the unirradiated femoral(More)

A typical cache accesses a block, then returns a selected word. In a pack computer design, the cache accesses and returns a block to the computer. The computer selects the word from the block and also retains blocks for reuse. The retained blocks constitute a software cache.Separate block wide caches for instructions, read data, and write data provide(More)
The wide channel design approach integrates vector and general purpose computing. Wide word accesses to a cache move several instructions per access or a few operands per access, thereby allowing a slower and somewhat larger cache. Channel commands control the movement of wide words in wide channels. Wide channels load data, vectors, instructions, and(More)
Ratings of student clinical performance were analyzed to determine consistency of supervisor and coordinator judgements of the same students as they progressed through medical school and on into the internship. The results suggested that students were consistently and progressively rated higher.
The purpose of this study was to test a theory of affective learning and to develop a data-gathering instrument for evaluation of affective learning. Two primary areas of affective learning were conceptualized for study: coping with feelings about professional knowledge and coping with feelings about the necessity for development of professional attitudes(More)
