In nearest larger value (NLV) problems, we are given an array A[1..n] of numbers, and need to preprocess A to answer queries of the following form: given any index i ∈ [1, n], return a “nearest” index j such that A[j] > A[i]. We consider the variant where the values in A are distinct, and we wish to return an index j such that A[j] > A[i] and |j − i| is minimized, the nondirectional NLV (NNLV) ...

A patient with active giant cell arteritis developed paraparesis and dissociated sensory loss due to infarction in the anterior spinal artery territory at the level of T12. Three days later fatal basilar artery thrombosis occurred. No occlusive lesion was found to explain the anterior spinal artery syndrome but this was associated with active arteritis. Alternative possibilities are that thromb...

The problem of planning the layout of containers on board supply vessels can be reformulated as the problem of packing a given set of rectangles into a larger rectangle, subject to constraints. A method combining the use of guillotine cuts with forward checking is proposed, and compared to standard forward checking on finite domains. The initial results show that the method has potential for im...

Blood vessel walls are built and maintained by 2 interdependent cell types, endothelial cells and mural cells. Signals exchanged between these 2 cell types control the formation, maturation, remodeling, and function of microvascular networks. Mural cells are either pericytes in the microvasculature or smooth muscle cells (SMCs) in larger vessels. Interactions between endothelial cells and mural...

The tissues of five patients who died following 4-31 months of continuous oral triparanol therapy have been analyzed for sterol content by gas-liquid chromatographic techniques. Desmosterol was present in variable amounts in all tissues examined, with the exception of nervous tissue, but in none of the tissues did desmosterol constitute a larger fraction of total sterols than that observed in t...

Mechanism of coronary spasm was examined regarding endothelium-related relaxation and contraction produced by smooth muscle cells of spastic vessels isolated from Gottingen miniature pigs. In these pigs, coronary artery spasm was documented angiographically in vivo three months after endothelial denudation, and spastic and control segments of the coronary artery were suspended in organ chambers...

Innervation of the coronary vessels is initiated before the 30 mm. stage of development. All the main branches of the coronary arteries are formed and in their definitive positions by the 40 mm. stage. Two plexuses have been shown for all the larger vessels after the 120 mm. stage. There are coarse-fibre and fine-fibre plexuses, situated at different levels in the tunica adventitia. Ganglion ce...

We have measured the effects of barium-induced cardiac contraction on the intramyocardial blood volume content of all vessels and have independently measured the blood volume content of vessels with a diameter greater than 100 ,um in rat myocardium. Measurements of total intramyocardial blood volume were made by using [1251]albumin as a plasma marker and technetium-99m as a red blood cell marke...
