Abstract:High-amylose cereal starch has a great benefit on human health through its resistant starch (RS) content. Enzyme hydrolysis of native starch is very helpful in understanding the structure of starch granules and utilizing them. In this paper, native starch granules were isolated from a transgenic rice line (TRS) enriched with amylose and RS and hydrolyzed by α-amylase. Structural properties of hydrolyzed TRS starches were studied by X-ray powder diffraction, Fourier transform infrared, and differential scanning calorimetry. The A-type polymorph of TRS C-type starch was hydrolyzed faster than the B-type polymorph, but the crystallinity did not significantly change during enzyme hydrolysis. The degree of order in the external region of starch granule increased with increasing enzyme hydrolysis time. The amylose content decreased at first and then went back up during enzyme hydrolysis. The hydrolyzed starches exhibited increased onset and peak gelatinization temperatures and decreased gelatinization enthalpy on hydrolysis. These results suggested that the B-type polymorph and high amylose that formed the double helices and amylose-lipid complex increased the resistance to BAA hydrolysis. Furthermore, the spectrum results of RS from TRS native starch digested by pancreatic α-amylase and amyloglucosidase also supported the above conclusion. © 2011 American Chemical Society.

Abstract:A rapid synchronous spectrofluorimetric method was first developed for the simultaneous determination of folic acid and riboflavin in nutrimental beverages. Folic acid could be detected by using H2O2 plus Cu(II) as oxidation system to produce pterine-6-carboxylic acid, which had strong fluorescence in aqueous solution, and riboflavin itself was obviously fluorescent. Various operational parameters were thoroughly discussed in terms of their effects on the fluorescence signals, including instrumental parameters, concentration of the oxidation system, and pH. Under optimum conditions, the calibration curves were linear in the ranges of 100-250 μg/L for folic acid and 1-250 μg/L for riboflavin, and the detection limits were 2.0 and 0.014 μg/L, respectively. In addition, this method was applied to the determination of folic acid and riboflavin in nutrimental beverages with satisfactory results. © 2011 American Chemical Society.

Abstract:With increasing of the Web pages, more and more ads for a variety of web text content appeared. Many scholars dedicated to recommendation system ads based contextual text. However, images, audio, video, etc. are also widely used in Web pages and other online systems due to extensive use of multimedia, to recommend ads for multimedia data are becoming trends in the future. In this paper, we recommend advertisements by utilizing a variety of vector features of track during online music operation. Specifically, our algorithm contains three parts in a principled approach: First, we linked tracks to ads by creating an optimal objective function D; Secondly, we created a algorithm model including features of tracks and ads; Finally, we found out ads based on model by estimating the relevance between different space as accurately as possible. Experimental results show that recommended method is effective and can be applied to online ads system. © 2011 Binary Information Press December, 2011.

Abstract:A thermally responsive polymer, termed as P(IPAAm-AM-BisAM), was prepared by the copolymerization of N-isopropyl acrylamide, acrylamide, and N,N′-methylenebisacrylamide. At room temperature this polymer was dissolved in water to form a low viscous solution so that it could be loaded in a capillary easily. When a high voltage was applied on the capillary, the polymer was stimulated by the Joule heat and transferred from a liquid state into a solid state, acting as a sieving matrix for the separation of proteins according to their molecular weights. The logarithm values of the molecular weights of the proteins correlated linearly with the migration times. This capillary gel electrophoresis of proteins was carried out using a conventional instrument. Using such a copolymer, we can easily realize high-speed, high-efficiency and reproducible capillary gel electrophoresis for proteins without any instrumental rebuilding or investment. © 2011 The Royal Society of Chemistry.

Abstract:Marginal Fisher analysis (MFA) is a representative margin-based learning algorithm for face recognition. A major problem in MFA is how to select appropriate parameters, k1 and k2, to construct the respective intrinsic and penalty graphs. In this paper, we propose a novel method called nearest-neighbor (NN) classifier motivated marginal discriminant projections (NN-MDP). Motivated by the NN classifier, NN-MDP seeks a few projection vectors to prevent data samples from being wrongly categorized. Like MFA, NN-MDP can characterize the compactness and separability of samples simultaneously. Moreover, in contrast to MFA, NN-MDP can actively construct the intrinsic graph and penalty graph without unknown parameters. Experimental results on the ORL, Yale, and FERET face databases show that NN-MDP not only avoids the intractability, and high expense of neighborhood parameter selection, but is also more applicable to face recognition with NN classifier than other methods. © 2011 Higher Education Press and Springer-Verlag Berlin Heidelberg.

Abstract:This paper formulated the spectrum allocation problem as a duopoly market with vertical differentiation in cognitive radio environment. The vertical differentiation showed the not fully substitutability of similar channels. It used static Cournot game model to acquire demand functions. On the basis it presented dynamic Cournot game model to compute the stable region and equilibrium. After determining the convergence condition of stable state, we conducted the simulation. The results show when the speed adjustment parameter is a smaller value and in the stable region, game is smooth and achieves the ultimate Nash equilibrium in a short time. The profit of primary user is more related to channel quality instead of spectrum allocation amount. Because of the not fully substitutability and marginal cost, the primary user who lends too much spectrum could not improve its profit even decrease it sometimes. © 2011 Binary Information Press December, 2011.

Abstract:The model selection for the chamber structure of large-scale navigation lock has a great influence on the quantities of chamber. This paper combines with an actual engineering to analysis the chamber structure of navigation lock with the help of 3D finite element. The analysis result shows that the chamber structure with double-hinges bottom board can reduce the thickness and reinforcement quantity of center inner bottom plating, bending moment of center inner bottom bottom plate is smaller than other times, because the chamber wall can't transfer bending moment to center inner bottom plate with the role of hinges. The chamber structure with monolithic bottom board which is pointed construction joints also can reduce reinforcement quantity and engineering investment by decreasing span moment of center inner bottom plate, considering the weights of chamber wall and back fill has effects on the preloading of foundation in internal force analysis of the chamber structure. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

Abstract:A streptavidin functionalized capillary immune microreactor was designed for highly efficient flow-through chemiluminescent (CL) immunoassay. The functionalized capillary could be used as both a support for highly efficient immobilization of antibody and a flow cell for flow-through immunoassay. The functionalized inner wall and the capture process were characterized using scanning electron microscopy. Compared to conventional packed tube or thin-layer cell immunoreactor, the proposed microreactor showed remarkable properties such as lower cost, simpler fabrication, better practicality and wider dynamic range for fast CL immunoassay with good reproducibility and stability. Using α-fetoprotein as model analyte, the highly efficient CL flow-through immunoassay system showed a linear range of 3 orders of magnitude from 0.5 to 200ngmL-1 and a low detection limit of 0.1ngmL-1. The capillary immune microreactor could make up the shortcoming of conventional CL immunoreactors and provided a promising alternative for highly efficient flow-injection immunoassay. © 2011 Elsevier B.V.
