Algebraically explicit analytical solutions of unsteady conduction with variable thermal properties in cylindrical coordinate

The analytical solutions of unsteady heat conduction with variable thermal properties(thermal conductivity,density and specific heat are functions of temperature or coordinates)are meaningful in theory.In addition,they are very useful to the computational heat conduction to check the numerical solutions and to develop numerical schemes,grid generation methods and so forth.Such solutions in rectangular coordinates have been derived by the authors.Some other solutions for 1-D and 2-D axisymmetrical heat conduction in cylin drical coordinates are given in this paper to promote the heat conduction theory and to develop the relative computational heat conduction.     

Boundary Integral Equations and A Posteriori Error Estimates

Adaptive methods have been rapidly developed and applied in many fields of scientific and engineering computing, Reliable and efficient a posteriori error estimates play key roles for both adaptive finite element and boundary element methods. The aim of this paper is to develop a posteriori error estimates for boundary element methods. The standard a posteriori error estimates for boundary element methods are obtained from the classical boundary integral equations. This paper presents hyper-singular a posteriori error estimates based on the hyper-singular integral equations, Three kinds of residuals are used as the estimates for boundary element errors. The theoretical analysis and numerical examples show that the hypersingular residuals are good a posteriori error indicators in many adaptive boundary element computations.     

An improved simple power attack against Camellia’s key schedule

This paper presents an improved simple power attack against the key schedule of Camellia. While the original attack required an exact determination of the Hamming weight of intermediate data values based on power measurements, in this paper, two types of the simple power attack are presented and shown to be tolerant of errors that might occur in the Hamming weight determinations. In practical applications of the attack, such errors are likely to occur due to noise and distortion in the power measurements and their mapping to the Hamming weights of the data. To resist these attacks, the required design rationale of key schedules and several practical countermeasures are suggested.

Structural Research on Embedment of a Bare Deflated Spiral Case

Complete bearing spiral case has not been applied to large power stations in China so far. The proposal of applying complete bearing spiral case necessitates an analysis of the reliability of the spiral case structure and the security of units under various working conditions. In combination with practice of a project, this paper presents a three-dimensional nonlinear finite element static analysis of the concrete using a concrete smeared crack model by means of the well-known finite element method （FEM） software ABAQUS. The stress distribution of the spiral case and reinforcing bars, the range of damages in surrounding concrete, and the displacement of structure are quantified. The computational results indicate that the embedment method ensures the structure＇s safety in strength. At the same time, the result shows that this embedment is a kind of preponderant method for embedment in aspects of economy and technique of construction, and the application of this embedment method to the hydropower station is feasible provided that some proper engineering measures are taken to constrain the width of the concrete in accord with the code＇s requirements. The paper proves the security and reliability of the structural design of spiral case in hydropower station accordingly.

Multiplex detection of KRAS and BRAF mutations using cationic conjugated polymers

The mutation detections of KRAS and BRAF genes are of significant importance to predict the responses to anti-cancer therapy and develop new drugs. In this paper, we developed a multi-step fluorescence resonance energy transfer (FRET) assay for multiplex detection of KRAS and BRAF mutations using cationic conjugated polymers (CCP). The newly established detection system could detect as low as 2% mutant DNAs in DNA admixtures. By triggering the emission intensity change of CCP and the dyes labeled in the DNA, four possible statuses (three mutations and one wildtype) can be differentiated in one extension reaction. The detection efficiency of this new method in clinical molecular diagnosis was validated by determining KRAS and BRAF mutations of 51 formalin-fixed paraffin-embedded (FFPE) ovary tissue samples. Furthermore, the result of the CCP-based multi-step FRET assay can be directly visualized under UV light so that no expensive instruments and technical expertise are needed. Thus, the assay provides a sensitive, reliable, cost-effective and simple method for the detection of disease-related gene mutations.     

Approach in high precision topic-specific resource discovery on the web

The Internet presents numerous sources of useful information nowadays. However, these resources are drowning under the dynamic Web, so accurate finding userspecific information is very difficult. In this paper we discuss a Semantic Graph Web Search (SGWS) algorithm in topicspecific resource discovery on the Web. This method combines the use of hyperlinks, characteristics of Web graph and semantic term weights. We implement the algorithm to find Chinese medical information from the Internet. Our study showed that it has better precision than traditional IR (Information Retrieval) methods and traditional search engines.
