Dead-end elimination (DEE) is a powerful theorem for selecting optimal protein side-chain orientations from a large set of discrete conformations. The present work describes a new approach to dead-end elimination that effectively splits conformational space into partitions to more efficiently eliminate dead-ending rotamers. Split DEE makes it possible to complete protein design calculations tha...

Three-point bend (TPB) and wedge splitting (WS) tests have been conducted on three different concretes and the specific fracture energy GF determined on the basis of the concept of local fracture energy. The latter is influenced by the free back surface of a notched test specimen, as explained by Hu and Wittmann. Tests on three or four specimen sizes with four notch to depth ratios confirm the ...

Neuroepithelial (NE) cells, the primary stem and progenitor cells of the vertebrate central nervous system, are highly polarized and elongated. They retain a basal process extending to the basal lamina, while undergoing mitosis at the apical side of the ventricular zone. By studying NE cells in the embryonic mouse, chick and zebrafish central nervous system using confocal microscopy, electron m...

Eucalyptus pellita F. Muell. is currently the predominant tree species deployed for plantation establishment in some parts of Borneo, particularly Sabah state, Malaysia. Its low disease susceptibility, good growth and form, desirable wood properties make E. suitable development wet tropical regions south-east Asia. In spite many positive traits, practical field observations indicate that suscep...

Thispaper presents a method of simultaneous localization and mapping (SLAM) in indoor environment using extended Kalman filter (EKF) with the straight line segments as the adopted geometrical feature. By using conventional two dimensional laser range finder (LRF) as the main sensor, robot finds a number of points scanned from the surrounding environment.Split-and-Merge is one of the mostpopular...

a field study was conducted to determine the integration of split n fertilization and herbicide application on weed management and wheat (triticum aestivum l.) yield in shiraz, iran, in 2005/2006 and 2006/2007 growing seasons. the experimental design was split plot with four replications. main factors consisted of n timing and splitting, and sub plots included iodosulfuron–methyl–sodium plus me...

Preharvest fruit drop is a significant physiological problem that affects numerous commercially apple varieties, including ‘Gala.’ AVG and 1-MCP are two plant growth regulators commonly used to reduce by reducing ethylene synthesis perception, respectively. To optimize yield market acceptance, complete investigation of impacts on quality ‘Gala’ apples required. In this study, four trials were c...

for solving large sparse non-hermitian positive definite linear equations, bai et al. proposed the hermitian and skew-hermitian splitting methods (hss). they recently generalized this technique to the normal and skew-hermitian splitting methods (nss). in this paper, we present an accelerated normal and skew-hermitian splitting methods (anss) which involve two parameters for the nss iteration. w...
