摘要：
We explore the entanglement dynamics of two qubits embedded in one-dimensional (1D) and three-dimensional (3D) photonic crystals. Our 1D results show sudden death and sudden birth of the entanglement, restricted by the initial coherence and the population in the excited state as well as the detuning. The results for the 3D crystal show entanglement death but no birth. We also discuss the entanglement of N qubits in the aforementioned photonic crystals.
摘要：
In order to develop the software industry, it needs many high quality software engineers. As a result, how to cultivate high-level programmers has become a challenge to the department of computer science in Chinese universities. In this paper, the requirements of software industry are analyzed. Some new methods and suggestions to the design of programming course group are presented. Before teaching language courses, we should make students understand how to solute practical problem. This is the key idea of this paper.
摘要：
An unconditionally stable (US) wave equation (WE) perfectly matched layer (PML) absorbing boundary condition is implemented for two-dimensional (2-D) open region finite-difference time-domain (FDTD) simulation by virtue of weighted Laguerre polynomial expansion. This novel PML preserves unconditional stability as well as comparative accuracy to the original wave equation PML (WEPML). Numerical examples are included to verify high accuracy and efficiency of the proposed algorithm. (C) 2009 Wiley Periodicals, Inc.

摘要：
Using the documentation, questionnaire, Delphi Method, mathematical statistics, logical analysis and so on, this paper developed the measuring list from the teaching evaluation in the practical course of physical education for three types who are leaders, teachers and students. Through the trial assessment and experimental verification, the reliability and validity for the measurement and assessment are identified.
摘要：
The quantitative dependence of quark-gluon plasma (QGP)-formation probability ( PQGP) on the centrality of Au−Au collisions is studied using a bond percolation model. The PQGP versus the maximum distance Smax for a bond to form is calculated from the model for various nuclei and the PQGP at different centralities of Au−Au collisions for the given Smax are obtained therefrom. The experimental data of the nuclear modification factor RAA(pT) for the most central Au−Au collisions at sNN=200 and 130 GeV are utilized to transform Smax to sNN. The PQGP for different centralities of Au−Au collisions at these two energies are thus obtained, which is useful for correctly understanding the centrality dependence of the experimental data.

摘要：
Low back pain continues to be one of the most prevalent problems in health care today,which has caused disability, presented a heavy economic burden for society and influenced the life quality of patients. Clinicians must develop a more logical rationale for treatment.Only then can our efforts assist in curtailing the low back pain.The Individual diagnosis and treatment should be highlighted and exercise therapy for low back pain must be paid much attention in the clinic practice. The "two match" models must be closely followed.That is,matching the classification system of Low Back Pain to appropriate exercise mode.meanwhile,matching the physical fitness of patients to their exercise intensity, duration, frequency and exercise cautions.On that basis,the individual exercise therapy model for low back pain will be established,which will be featured as highly targeted and individualized.

摘要：
With the development of society, the impact of lifestyle on health playing an increasingly important role. This research is dedicated to conclude a comprehensive assessment of condition of constitution of 3786 heads of Government Organizations and Enterprises in Hubei province by means of implementation of constitution tests. Moreover, it investigates their lifestyles like smoking habit, sleep hours and quality as well as exercise among others, on the basis of which we try to have an insight of relationship between them. The aim of this research is to provide some effective measures by which Government Organizations and Enterprises could better their heads' constitution condition and to offer a scientific guide to instruct them to exercise and improve their lifestyle. This research finally indicates that the constitution condition of 3786 heads of Government Organization and Enterprises in Hubei province is obviously associated with their lifestyles like smoking habit, sleep hours and quality, daily walking hours, the frequency of exercise, general assessing result of constitution condition, BMI, WHR are closely associated with lifestyles.
摘要：
The particular noise in MRI is not only lower the quality of image but also making de-noising more difficultly. The multiwavelet with the orthogonality and symmetry decomposes the image more precisely and denoise better than wavelet. After decomposing the image using multiwavelet, A method combining threshold-selecting function with semi-soft thresholding is proposed to reduce the noise in MRI. The simulation results shows that the method is superior to others.
