is paper examines the nature of rst-mover advantages in the deployment of spatially differentiated surface transport networks. A number of factors explaining the existence of rst-mover advantages have been identi ed in the literature; however, the questions of whether these factors exist in spatial networks, and of how they play out with true capital immobility have remained unanswered. By exam...

Power training programs have proved to be effective in improving components of physical fitness such as speed. According to the concept of training specificity, it was postulated that exercises must attempt to closely mimic the demands of the respective activity. When transferring this idea to speed development, the purpose of the present study was to examine the effects of resisted sprint (RST...

The Test Template Framework (TTF) is a formal, abstract model of testing, used to derive a hierarchy of test information, including test inputs and outputs, from a model-based formal speciication. In this paper we propose two modiications to the framework: rst, that testing information derived from state components be factored out from operation-speciic information, and second, that focusing on...

Auricular flutter was first described by McWilliam in 1887 (Mackenzie, 1925) as a result of experimental stimulation. Ritchie (1905) obtained graphic records from the jugular vein, and Jolly and Ritchie (1908) (Mackenzie, loc. cit.) took electrocardiographic tracings from one of Ritchie's cases of auricular flutter. Mackenzie looking back through his old records found cases of auricular flutter...

After spinal cord injury, enzymatic digestion of chondroitin sulfate proteoglycans promotes axonal regeneration of central nervous system neurons across the lesion scar. We examined whether chondroitinase ABC (ChABC) promotes the axonal regeneration of rubrospinal tract (RST) neurons following injury to the spinal cord. The effect of a GSK-3beta inhibitor, lithium chloride (LiCl), on the regene...

Splatting is an object-order volume rendering algorithm that produces images of high quality, and several optimization techniques have been proposed. This paper presents new techniques that accelerate splatting algorithms by exploiting both object-space and image-space coherence. In particular, we propose two visibility test methods suitable for octree-based splatting. The rst method, based on ...
