This paper describes a new semi-global method for SFS (Shape-from-Shading) using graph cuts. The new algorithm combines the local method proposed by Lee and Rosenfeld [I] and the global inethod using energy minimization technique. By employing a new global energy minimization formulatioK the convedconcave ambiguity problcm of the Lee and Rosenfeld method can be resolved efficiently. A new combi...

Balanced structure and parameter search is critical to evolutionary design with genetic programming (GP). Structure Fitness Sharing (SFS), based on a structure labeling technique, is proposed to maintain the structural diversity of a population and combat premature convergence of structures. SFS achieves balanced structure and parameter search by applying fitness sharing to each unique structur...

SFS (secure file system) is a global file system designed to be secure against all active and passive network attacks, provide a single namespace across all machines in the world, and avoid any form of centralized control. Using SFS, any unprivileged user can access any file server in the world securely and with no prior arrangement on the part of system administrators. New file servers are imm...

Presented here is an analysis of the effects of soil-foundation-structure interaction (SFSI) on seismic response of highway bridges. Of particular importance is the issue of input motions, their scaling and application to the SFS models. The analysis presented in this paper addresses the influence of inelastic behavior of both the soil and the structural components during seismic response evalu...

ARAP2 is a protein that contains both ArfGAP and RhoGAP domains. We found that it is a phosphatidylinositol (3,4,5)-trisphosphate-dependent Arf6 GAP that binds RhoA-GTP but lacks RhoGAP activity. In agreement with the hypothesis that ARAP2 mediates effects of RhoA, endogenous ARAP2 associated with focal adhesions (FAs) and reduction of ARAP2 expression, by RNAi, resulted in fewer FAs and actin ...

Dynamic remodelling of actin stress fibres (SFs) allows non-muscle cells to adapt to applied forces such as uniaxial cell shortening. However, the mechanism underlying rapid and selective disassembly of SFs oriented in the direction of shortening remains to be elucidated. Here, we investigated how myosin crossbridge cycling induced by MgATP is associated with SF disassembly. Moderate concentrat...

Aberrant profiles of pre-mRNA splicing are frequently observed in cancer. At the molecular level, an altered profile results from a complex interplay between chromatin modifications, the transcriptional elongation rate of RNA polymerase, and effective binding of the spliceosome to the generated transcripts. Key players in this interplay are regulatory splicing factors (SFs) that bind to gene-sp...

OBJECTIVE To determine the validity and reliability of the 13-figure images scale (13-CS) and Standard Figural Stimuli (SFS) for the evaluation of body images in adolescent students from Bucaramanga. METHODS A probabilistic sample with 189 students was evaluated with the two scales. Two weeks later, the valuation together with the size, weight, percentage of body fat, SCOFF questionnaire and ...

Designing the new microstructure is an effective way to accelerate the biomedical application of magnesium (Mg) alloys. In this study, a novel Mg-8Er-1Zn alloy with profuse nano-spaced basal plane stacking faults (SFs) was prepared by combined processes of direct-chill semi-continuous casting, heat-treatment and hot-extrusion. The formation of SFs made the alloy possess outstanding comprehensiv...
