The 1921 census gives 102,513 as the number of lepers in India, but mentions that this is short of the real number, as only conspicuous sufferers from this disease were likely to be enumerated by the untrained people who gathered the statistics. Recently, an estimate was made by the sanitation staff of a certain town in India that there were only six lepers in a certain ward of the town. Immedi...

This paper describes a new Image Based Rendering technique aimed at increasing the realism of textured cylindrical surfaces by adding 3D details and enhancing the depth conceived by the viewer. Cylindrical relief texture mapping extends the existing work on planar relief textures by using cylinders as warp surfaces. After mapping the planar relief texture to a reference cylinder, cylindrical wa...

Bacterial responses to decreasing osmolality involve mechanosensitive channels. The crystal structure has been determined of the small conductance mechanosensitive channel (MscS) from Escherichia coli, providing new insights into mechanical and voltage sensing by this and other channel proteins.

This paper generalizes Markov Random Field (MRF) stereo methods to the generation of surface relief (height) fields rather than disparity or depth maps. This generalization enables the reconstruction of complete object models using the same algorithms that have been previously used to compute depth maps in binocular stereo. In contrast to traditional dense stereo where the parametrization is im...

How traffic congestion is evaluated can significantly affect transport planning decisions. This report describes various factors that affect congestion cost estimates and the evaluation of potential congestion reduction strategies, including analysis scope, baseline speeds, travel time valuation, accident and emission impact analysis, induced travel analysis, and consideration of co-benefits. I...

1 Mohacsi PJ,Thompson JF, Nicholson JK, Tiller DJ. Patients’ attitudes to xenotransplantation. Lancet 1997; 349: 1031. In the absence of a political solution, we believe that there are only two ethical alternatives. Preferably, more autonomy should be granted to the refugees and aid should be targeted towards restoring their livelihoods. Such a change would probably involve dividing the camps i...

By S. D. S. GREVAL LIEUTENANT-COLONEL, late I.M.S. Scrolof/ist. to the Government of India, School of Tropical Medicine, Calcutta The following is a typical case. After a deed of violence and a domestic tragedy the victim and family are much more concerned about the revenge than the relief. Precious hours which if availed of in seeking medical relief can save the life of the victim are spent in...
