    Abstract: Biclustering is one of the important techniques for gene expression data analysis. A bicluster is a set of genes coherently expressed for a set of biological conditions. Various biclustering algorithms have been proposed to find biclusters of different types. However, most of them are not efficient. We propose a novel algorithm MRCluster to mine constant row biclusters from real-valued dataset. MRCluster uses Apriori property and several novel pruning techniques to mine biclusters efficiently. We compare our algorithm with a recent approach RAP, and experimental results show that MRCluster is much more efficient than RAP in mining biclusters with constant rows from real-valued gene expression data.

    Nonlinear Periodic Oscillations of Micro-Voids in a Class of Incompressible Hyper-Elastic Spheres
    Trans Tech Publications, Ltd. ; 2011

    Abstract: The problem of radially symmetric motion is examined for a pre-existing micro-void in the interior of a sphere under a suddenly applied outer surface tensile load, where the sphere is composed of a homogeneous incompressible hyper-elastic material. Through qualitatively analyzing the second-order ordinary differential equation that describes the motion of the pre-existing micro-void with time, some interesting conclusions are proposed. For any given values of surface tensile loads, it is proved that the motion of the pre-existing micro-void with time presents a nonlinear periodic oscillation, however, in certain cases, the oscillation amplitude increases discontinuously with the increasing values of surface tensile loads. Finally, based on the known transversely isotropic incompressible Gent-Thomas material model as an example, numerical simulations are carried out.

    A 600V-Class Partial SOI LDMOS with Step-Doped Drift Region

    In: Advanced Materials Research, Trans Tech Publications, Ltd., Vol. 1096 ( 2015-4), p. 514-519
    Abstract: A 600V-class lateral double-diffused metal-oxide-semiconductor (LDMOS) field-effect transistor with step-doped drift region (SDD) in partial silicon-on-insulator (PSOI) is introduced to improve breakdown voltage (BV) and reduce on-resistance (Ron). The step-doped method induces an electric field peak in the surface of the device, which can reduce the surface field in the device and adjust the doping accommodation in the drift region. The adjusted drift region can allow higher doping concentration under the drain end which results in higher breakdown voltage, and accommodate more impurity atoms as a whole which provides more electrons to support higher current and thus reduce on-resistance.

    Abstract: Sour pickled cabbage is a traditional Chinese food, which was made with fresh vegetables such as cabbage. Because of its naturally fermentation, a lot of lactic acid bacteria are riched in it. However, the traditional naturally fermented sour pickled cabbage were home-made in China, because of the difference of raw material, processing, formula and other factors, the flavor, nutrition and safety of them varied significantly, in order to investigate the influencing factors affected the flavor, quality and security of the naturally fermented sour pickled cabbage, and discuss the relationship between chemical composition and the flavor, quality and security, the acidity, total sugar, nitrite, protein and sodium chloride levels of 5 naturally fermented sour pickled vegetables by means of acid-base titration method, the direct titration, the hydrochloric acid naphthalene ethylenediamine kieldahl method, the indirect precipitation titration method respectively. The results were showed as follow, the acidity were between 0.283% and 0.891%, the total sugar content were between 3.96% to 4.37%, the nitrate content were 0.167 g/kg to 0.267 g/kg, the protein content were between 0.0169% and 0.0218%, the sodium chloride content were between 0.412% and 0.447% respectively.

    Wear Process and Analysis of Lubrication Failure about Sputtering MoS〈sub〉2〈/sub〉 Composite Solid Films Applied to Spacecraft

    Abstract: The solid MoS 2 composite films which were doped with Sb 2 O 3 were investigated by means of UMT-2 tribometer. The worn surface morphology of balls and discs during different worn phases were measured on a high resolution microscope. The main chemical elements S,Mo in the worn surface were analyzed with PHI-5720 XPS. The worn areas of discs during different worn phases were measured with the aid of a nano scratch meter(CSM,Switzerland) .The results showed that the MoS 2 /Sb 2 O 3 composite films had better oxidation resistance properties and longer wear-life(6.5×10 5 r).The model of contact between the ball and its counterpart (steel disc) was converted into flat contact during the wear test. The MoS 2 transferred from discs to the surface of the balls helped to contribute their longer wear-life. Continually accumulated wear at the interface between balls and their respective counterpart discs resulted in their lubrication failure, and the accompanying oxidation of MoS 2 occurring partially accelerated lubrication failure of the solid MoS 2 composite lubrication films.

    LDPC Codes with the Layered LLR-BP Algorithm for 3GPP

    In: Applied Mechanics and Materials, Trans Tech Publications, Ltd., Vol. 462-463 ( 2013-11), p. 720-723
    Abstract: We propose a layered log-likelihood-ratio-based belief propagation(LLR-BP)algorithm for Low Density Parity Check (LDPC)codes. In the conventional decoding algorithm, the process of decoding would be terminated when it reaches the maximum iterative number or the near-convergence is achieved. The proposed algorithm is based on the variable node information quantification and stop updating criterion thought. By dividing the absolute value of the variable node to different layers, a part of the check nodes stop the iteration before reaching the maximum iterative number to save iterative time. From the simulation results, we know that the improved decoding algorithm successively achieves lower computation complexity than the conventional one .And the layered LLR-BP algorithm is a better scheme for LDPC codes.

    In: Advanced Materials Research, Trans Tech Publications, Ltd., Vol. 1048 ( 2014-10), p. 378-382
    Abstract: Hydrogenated amorphous carbon (a-C:H) films were prepared by microwave plasma chemical vapor deposition (MW-PCVD) technique with a mixture of acetylene and hydrogen. The morphology of three-phase a-C:H films, such as graphite-like, diamond-like and polymer-like were modulated by microwave power, deposition pressure, and flow ratios. Meanwhile, annealing does not seem to change the surface morphology or the film structure. The phase transitions are not found during the different annealing temperatures, showing that a-C:H films have a good thermal stability.

    Abstract: Genetic diversity analysis and population structure can estimate genetic variation of diverse materials, and can be used in germplasm management and varietal protection. In this study, the genetic diversity and population structure for tobacco germplasm (78 cultivated tobacco accessions in China) were analyzed by using 28 SSR markers. A total of 127 alleles were detected with an average of 4.5 per locus in 78 accessions, while PIC values ranged from 0.19 to 0.89 with an average of 0.63 per marker. Based on genetic similarity, most of sun-cured and flue-cured tobacco accessions were clustered into group A and group B, respectively. A model-based structure analysis for these accessions detected two subpopulations, which were generally coincident with the clustering analysis and showed the genetic similarities were relative high for these accessions. These results revealed narrow genetic diversity for the tobacco germplasm in China.
