Anisotropic mesh adaptation is studied for linear finite element solution of 3D anisotropic diffusion problems. The M-uniform mesh approach is used, where an anisotropic adaptive mesh is generated as a uniform one in the metric specified by a tensor. In addition to mesh adaptation, preservation of the maximum principle is also studied. Four different metric tensors are investigated: one is the ...

BACKGROUND Socket preservation after tooth extraction is one of the indications of bone grafting to enhance preorthodontic condition. The aim of this study is to determine the effects of socket preservation on the immediate tooth movement, alveolar ridge height preservation and orthodontic root resorption. MATERIALS AND METHODS In a split-mouth technique, twelve sites in three dogs were inves...

The Piedmont enjoys a highly regarded reputation for its historic sites and its world-class preservation practices. The well-preserved homes of presidents and extraordinary examples of architecture, known worldwide, dominate our landscape. We see daily the many ways in which preservation work enriches the lives of people who live in, work in, and visit our community. Numerous residents in the P...

Slow feature analysis (SFA) is an unsupervised-learning algorithm that extracts slowly varying features from a multi-dimensional time series. A supervised extension to SFA for classification and regression is graph-based SFA (GSFA). GSFA is based on the preservation of similarities, which are specified by a graph structure derived from the labels. It has been shown that hierarchical GSFA (HGSFA...

Involuntary movements share much of the motor control circuitry used for voluntary movement, yet the two can be easily distinguished. The Kohnstamm phenomenon (where a sustained, hard push produces subsequent involuntary arm raising) is a useful experimental model for exploring differences between voluntary and involuntary movement. Both central and peripheral accounts have been proposed, but l...

Hurdle technology is a method of ensuring that food products will be safe for consumption and extending their shelf life. It also ensures that pathogens in food products will be eliminated. Hurdle technology is used in food industry for the gentle but effective preservation of foods. The shelf life, sensory and nutritional quality of foods are based on applications of combined preservative fact...

THE REDUCTION in metabolic rate effected by hypothermia constitutes the central tenet of traditional organ preservation. The antithesis of this approach is to provide for metabolic demand during normothermic preservation. This latter strategy has two potential benefits. First, if metabolic requirements are met during preservation, then longer preservation with better posttransplant function may...
