The dynamic actin cytoskeleton is important for a myriad of cellular functions, including intracellular transport, cell division, and cell shape. An important regulator of actin polymerization is the actin-related protein2/3 (Arp2/3) complex, which nucleates the polymerization of new actin filaments. In animals, Scar/WAVE family members activate Arp2/3(More)
After evaluating performances of the directional median (DM) filter and the adaptive switching median (ASWM) filter, we propose an adaptive median filter for restoring images by using local texture information in images. It contains two steps: 1) identifying noise pixels; 2) estimating the values of the noise pixels. Firstly, a double-layer window is(More)
—Expansion of query keywords based on semantic relations is an effective approach to improve the performance of information retrieval. Traditional methods of query expansion did not adequately make use of semantic relations between query keywords. In this paper, a novel approach for query expansion is presented. The main idea of the approach is to construct(More)
Salinity in soils is among the major constraints of agricultural and forestry productivity worldwide. To investigate the basis of salt tolerance in Salix matsudana Koidz (Chinese willow), comparative proteomes of 1.5-month-old cuttings were analyzed using two-dimensional gel electrophoresis (2-DE). Proteins were extracted from roots of plants grown under(More)
NetFlow is a popular technology in network management nowadays. It supports administrators to get various performance metrics. But metric values estimated from NetFlow records may inaccurate in some circumstance. This paper aims at studying the errors of utilized bandwidth measured by NetFlow. At first, packet streams with a specific format were collected(More)
MicroRNAs are small and non-coding RNA molecules with the master role in regulation of gene expression at post-transcriptional/translational levels. Many methods have been developed for microRNA loss-of-function study, such as antisense inhibitors and sponges; however, the robustness, specificity, and stability of these traditional strategies are not highly(More)
Internet flows characteristics are important reference for network behaviors research. However, there are few latest related studies and comparative analysis on different networks is especially rare. Based on traffic traces from CAIDA and CERNET, this paper presents a detailed and comprehensive comparison on Internet flows characteristics, including the(More)
BACKGROUND Nucleoside analogues are recommended as antiviral treatments for patients with hepatitis B virus (HBV)-associated liver failure. Clinical data comparing entecavir (ETV) and lamivudine (LAM) are inconsistent in this setting. OBJECTIVES To compare the efficacy and safety of ETV and LAM in patients with chronic hepatitis B (CHB)-associated liver(More)
