We examine the large deformation elastic response of the spectrin network in a human red blood cell (RBC) on the basis of molecular-level constitutive laws. These formulations are shown to be consistent with the predictions of continuum level models for the hyperelastic deformation of RBC, and are compared with recent experimental studies of whole-cell(More)
A water-soluble neutral polysaccharide (GLP-F1-1) was isolated from the fruiting bodies of Ganoderma lucidum by DEAE Sepharose Fast Flow and Sephacryl S-500 High Resolution Chromatography. The neutral polysaccharide had an average molecular weight (Mw) of approximately 2.5×10(6) kDa. GC analysis showed that this polysaccharide was mainly composed of glucose(More)
In this paper, a novel method is proposed to identify plant species by using the two- dimensional multifractal detrended fluctuation analysis (2D MF-DFA). Our method involves calculating a set of multifractal parameters that characterize the texture features of each plant leaf image. An index, I 0, that characterizes the relation of the intra-species(More)
Interferometric synthetic aperture radar (SAR) filtering is a crucial processing step in topography reconstruction and deformation measurement. The high-resolution interferograms over vegetation or urban areas are heterogeneous, which will violate the local stationarity assumption and make it difficult to obtain a large number of independent and identically(More)
Response surface methodology was employed to optimize the conditions for alkaline extraction of polysaccharides from Ganoderma lucidum. The results indicated that the optimum conditions were an extraction temperature of 60.1 degrees C, an extraction time of 77.3 min, a sodium hydroxide (NaOH) concentration of 5.1% and a substrate/liquid ratio of 1:21.4.(More)
Products rich in 1,3-dibehenoyl-2-oleoyl glycerol (BOB) triglyceride (TAG) were produced by enzymatic interesterification of high oleic acid sunflower oil (HOSO) and behenic acid methyl ester (BME) by 1,3-regiospecific lipase Lipozyme RM IM in a solvent-free system. The impact factors of enzyme load, substrate molar ratio of BME to HOSO (BME/HOSO), reaction(More)
A series of Au/alpha-Fe2O3 catalysts promoted with ZrO2 and Nb2O5 were prepared by parallel co-precipitation method. Detailed characterizations were conducted by techniques including UV-Vis-DRS, XPS, TEM and XRF. Results indicated that the enrichment of Au, ZrO2 and Nb2O5 on the surface induced by the strong interaction between ZrO2 and Nb2O5 kept the(More)
Phase unwrapping, a process of recovering the real phase from ambiguous one, is one of key techniques for interferometric synthetic aperture radar (InSAR) data processing. The larger interferograms make the phase unwrapping to be a more challenging task. A novel fast phase unwrapping method is proposed in this paper which is very effective in dealing with(More)
For Au-ceria catalysts prepared by deposition-precipitation method, the catalytic performance of water gas shift reaction was studied with different La loadings. In the complete doping range, ceria retains with its cubic fluorite structures. XRD, HRTEM and UV-Vis-DRS, studies showed that La doping can improve the activity of Au-ceria catalyst by stabilizing(More)
