BACKGROUND Chitinases are prevalent in life and are found in species including archaea, bacteria, fungi, plants, and animals. They break down chitin, which is the second most abundant carbohydrate in nature after cellulose. Hence, they are important for maintaining a balance between carbon and nitrogen trapped as insoluble chitin in biomass. Chitinases are(More)
This paper describes the speech and audio codec that has been submitted to ITU-T by Huawei and ETRI as a candidate for the up-coming super-wideband and stereo extensions of Rec. G.729.1 and G.718. The core codec in the current implementation is G.729.1 and the encoded frequency range is increased from 7 kHz to 14 kHz. Therefore, the maximum bit rate is(More)
This paper introduces a novel and highly efficient realization of a spherical vector quantizer (SVQ), the " Gosset Low Complexity Vector Quantizer " (GLCVQ). The GLCVQ codebook is composed of vectors that are located on spherical shells of the Gosset lattice E8. A high encoding efficiency is achieved by representing the spherical vector codebook as(More)
Tight control of cell-cycle progression is critical for T-lymphocytes to function properly. Slfn1 (Schlafen1) has been reported to play an important role in the establishment and maintenance of quiescence in T-lymphocytes. However, how Slfn1 accomplishes this critical function remains poorly understood. In the present study, we show that nuclear(More)
Multi-scale segmentation is an essential step toward higher level image processing in remote sensing. This paper presents a new multi-scale segmentation method based on Statistical Region Merging (SRM) for initial segmentation and Minimum Heterogeneity Rule (MHR) for merging objects where high resolution (HR) QuickBird imageries are used. It synthesized the(More)
Remote sensing images fusion can not only improve the spatial resolution for the original multispectral image, but also preserve the spectral information to a certain degree. In order to find out the fusion algorithm which is suited for QuickBird images fusion, four simple fusion algorithms, Multiplication (MLT), Modified Brovey (MB), High-Pass Filter (HPF)(More)
Creatine kinase catalyzes the reversible transfer of the N-phosphoryl group from phosphocreatine to ADP to generate ATP and plays a key role in highly energy-demanding processes such as muscle contraction and flagellar motility; however, its role in signal transduction (which frequently involves ATP-consuming phosphorylation) and consequent cell-fate(More)
Amyloid accumulation in the brain of Alzheimer's patients results from altered processing of the 39- to 43-amino acid amyloid β protein (Aβ). The mechanisms for the elevated amyloid (Aβ(1-42)) are considered to be over-expression of the amyloid precursor protein (APP), enhanced cleavage of APP to Aβ, and decreased clearance of Aβ from the central nervous(More)
To advance our understanding of the protein folding process, we use stopped-flow far-ultraviolet (far-UV) circular dichroism and quenched-flow hydrogen–deuterium exchange coupled with nuclear magnetic resonance (NMR) spectroscopy to monitor the formation of hydrogen-bonded secondary structure in the C-terminal domain of the Fas-associated death domain(More)
OBJECTIVES The aim of this study was to identify serum proteins with differential concentrations between hepatocellular carcinoma (HCC) patients and HBsAg asymptomatic carriers among individuals infected with hepatitis B virus (HBV) with basal core promoter (BCP) double mutations (A1762T, G1764A). METHODS iTRAQ and liquid chromatography-tandem mass(More)
