Laws of Large Numbers for Random Linear
The computational solution of large scale linear programming problems contains various difficulties. One of the difficulties is to ensure numerical stability. There is another difficulty of a different nature, namely the original data, contains errors as well. In this paper, we show that the effect of the random errors in the original data has a diminishing tendency for the optimal value as the...
متن کاملSome impressions of Sungei Buloh Leper Hospital under Japanese occupation.
The Conference was, ·at this time, a peculiarly appropriate one. It met at a stage in which many of our ideas about the disease are in the melting pot. It represented the resumption, after the preoccupations of a world war, of international linkage against leprosy.

For the last forty years, the vestry of St Mary's Church, Melton Mowbray, has been home to a remarkable, yet little known, piece of medieval sculpture known locally as the "leper head" and linked by tradition to the nearby hospital foundation at Burton Lazars. Doubts have been cast on this over the years by both professional and amateur historians, who have alleged that the distinctive features...
متن کاملThymic emigration revisited
Conventional alphabeta T cell precursors undergo positive selection in the thymic cortex. When this is successful, they migrate to the medulla and are exposed to tissue-specific antigens (TSA) for purposes of central tolerance, and they undergo maturation to become functionally responsive T cells. It is commonly understood that thymocytes spend up to 2 wk in the medulla undergoing these final m...
متن کاملChemorepulsion and thymocyte emigration.
The possibility that chemorepulsion, or cell migration away from a stimulus, plays a role in the immune system is exciting from both clinical and cellbiological viewpoints. For the clinician, what could be a more satisfying way to treat a cell-mediated immune disease than local application of a chemorepellent? For the cell biologist, eukaryotic cell chemorepulsion represents a novel behavior to...
