BACKGROUND The purpose of this survey was to confirm the prevalence and adverse profiles of fatty liver disease among different ethnic public servants in Urumqi of Xinjiang. METHODS The cross-sectional study were implemented among serving and retired public servants who participated in the annual physical check-up including abdominal ultrasonography from April 2012 to April 2013 at the health...

Large strains, anisotropy of mechanical properties of materials and Coulomb friction in contact regions are some properties in the analysis of deep drawing process. In this research, the effects of different parameters such as anisotropy coefficient, work hardening exponent and friction coefficient on deep drawing process of drawing quality steel are studied. For this purpose, the finite elemen...

Flavodoxins, which exist widely in microorganisms, have been found in various pathways with multiple physiological functions. The flavodoxin (Fld) containing the cofactor flavin mononucleotide (FMN) from sulfur-reducing bacteria Desulfovibrio gigas (D. gigas) is a short-chain enzyme that comprises 146 residues with a molecular mass of 15 kDa and plays important roles in the electron-transfer c...

Flavodoxin (Fld) has been demonstrated to bind to ferredoxin- NADP(+) reductase A (FprA) in Pseudomonas putida. Two residues (Phe(256), Lys(259)) of FprA are likely to be important for interacting with Fld based on homology modeling. Sitedirected mutagenesis and pH-dependent enzyme kinetics were performed to further examine the role of these residues. The catalytic efficiencies of FprA-Ala(259)...

A class of image-matrix-based feature extraction algorithms has been discussed earlier. The correspondence argues that 2-D principal component analysis and Fisher linear discriminant (FLD) are equivalent to block-based PCA and FLD. In this correspondence, we point out that this statement is not rigorous.

This paper presents a new algorithm for feature generation, which is approximately derived based on geometrical interpretation of the Fisher linear discriminant analysis. In a field of pattern recognition or signal processing, the principal component analysis (PCA) is often used for data compression and feature extraction. Furthermore, iterative learning algorithms for obtaining eigenvectors ha...

BACKGROUND Several studies have evaluated accuracy of intraoral scanners (IOS), but data is lacking regarding variations between IOS systems in the depiction of the critical finish line and the finish line accuracy. The aim of this study was to analyze the level of finish line distinctness (FLD), and finish line accuracy (FLA), in 7 intraoral scanners (IOS) and one conventional impression (IMPR...

forming limit curves are used as a parameter in finite element analysis to control the material's level of formability. in this research, forming limit diagram (fld) of ss304l sheet was obtained by abaqusfinite element software. in practice, the experimental determination of a forming limit curve is a very time-consuming procedure which requires special and expensive equipment. forming limit di...

The deadline assignment problem arises in distributed systems where each subtask composing a distributed task must receive a local deadline such that the task end-to-end deadline is met. It also arises in multi-hop networks where the maximum sojourn time of a flow on each visited node must be bounded by a local deadline that allows the flow end-to-end deadline to be met. We first formalize the ...
