Algorithms are tentatively modified by adding refraction effect due to inhomogeneous media. Robust Capon beam-forming (RCB) algorithm is used for confocal procession. A frequently-used three-dimensional (3-D) hemispherical breast model is selected. Electrical parameters of breast tissues are modeled by a multi-pole Cole-Cole model in order to consider frequency-dependent property. Finite-difference time-domain (FDTD) method is used to simulate wave propagation in breast with illumination of an ultra-wide band (UWB) plane wave source. In a numerical application, two spherical 3 mm-radius tumors are added into breast to test performance of original CMI method and modified version. It shows that there is improvement on computational precision with slight increase in computational complexity. © 2017, Editorial Board of Chinese Journal of Computational. All right reserved.

The change rule for 186 sets of the consumer price index (CPI) from 2000 to 2015 in China can be described using the channel principle. A channel is similar to a road map. Chebyshev's principle of optimal approximation states that at the center of the CPI function, all CPI data comprise a channel with a maximum safety range to minimize the positive or negative maximum error that serves as the boundary. When the endpoint data are assumed as the maximum weight based on zero error data, the CPI will not suddenly change in the near future or will change with an error that is less than the positive or negative maximum error within the channel. Therefore, the extension of the channel can forecast future changes in the CPI and the fluctuation range. This study introduces the basic principle and method, applicable scope, judging rules, and specific algorithm of the CPI channel. Many examples of data processing illustrate that a simple and direct-viewing linear channel can be easily calculated and has a wide application scope. The examples also verify that CPI changes in the near future are basically predictable and controllable.

In this paper, the human capital Gini coefficient of China's 30 provinces from 2006 to 2012 was calculated and compared using annual cross-sectional data of and the per capita GDP correlation inspection. Results show that the human capital Gini coefficient of each region is relatively high, and the interregional gap in human capita is manifested by its distributed structure. Human capital inequality and human capital level were found to be negatively correlated. By continuously improving the regional average years of schooling, the human capital Gini coefficient gradually decreased, although the human capital inequality in the three regional gaps did not change. The Gini coefficient of human capital and regional economic development are also negatively correlated. A shift in the former can cause significant changes in the per capita GDP, thereby making the regional human capital inequality gap the cause of the gaps in regional economy. On this basis, economic growth policy choice should not only focus on the stock of human capital but improving the distribution of human capital structure as well.

In this paper, we first present a relaxed gradient based iterative (RGI) algorithm for solving matrix equations A1XB1=F1 and A2XB2=F2. The idea is from (Niu et al., 2011; Xie and Ma, 2016) in which efficient algorithms were developed for solving the Sylvester matrix equations. Then the RGI algorithm is extended to solve the generalized linear matrix equations of the form AiXBi=Fi,(i=1,2,...,N). For any initial value, it is proved that the iterative solution converges to their true solution under some appropriate assumptions. Finally, a numerical example is given to illustrate that the introduced iterative algorithm is more efficient than gradient based maximal convergence rate iterative (GI) algorithm of Ding et al. (2010) in speed, elapsed time and iterative steps. © 2017 Elsevier Ltd.

In this Letter, we realized an enhanced optical rotation of the zero-order transmitted light through a silver film with an array of perforated S-shaped holes. Different from the previous studies, this effect results from the contribution of both the localized surface plasmons and surface plasmon polaritons (SPPs). The rotation angle can be modulated with the thickness due to the phase retardation of the SPPs when tunneling to the emitted surface. With a sample thickness 245 nm, a near-complete cross-polarization conversion (90 optical rotation) can be achieved, representing a major advance in performance compared to the previously reported planar chiral structures. © 2013 American Physical Society.

BiOI sensitized nano-Bi2WO6 photocatalysts with different BiOI contents were successfully synthesized by a facile deposition method at room temperature, and characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) high-resolution transmission electron microscopy (HR-TEM), photoluminescence (PL) spectra, UV-vis diffuse reflection spectroscopy (UV-vis DRS) and Brunauer-Emmett-Teller (BET) surface area measurements. The photocatalytic activity of BiOI/Bi2WO6 was evaluated by the photo-degradation of Reactive Brilliant Red (X-3B) in suspended solution and toluene in gas phase. It has been shown that the BiOI/Bi2WO6 catalysts exhibit a coexistence of both tetragonal BiOI and orthorhombic Bi2WO6 phases. With increasing BiOI content, the absorption intensity of BiOI/Bi2WO 6 catalysts increases in the 380-600 nm region and the absorption edge shifts significantly to longer wavelengths as compared to pure Bi 2WO6. The 13.2% BiOI/Bi2WO6 catalyst exhibits obviously higher UV and visible light photocatalytic activities than commercial P25, pure Bi2WO6 and BiOI, for the photodegradation of toluene and X-3B. The remarkably enhanced photocatalytic activities can be attributed to the fact that the proper BiOI sensitized nano-Bi2WO6 increase its BET surface area, decrease band-gap energy, enhance absorption in the 380-600 nm region and inhibit the recombination of photo-induced carriers. © 2012 Elsevier B.V.

This paper studies numerically the temperature reached by atomic force microscope tips illuminated by femtosecond laser pulses, in which the laser focusing dependence of tip heating is investigated in detail and the laser heating effects on different tips are discussed too. The results show that tip heating can be significantly reduced if the femtosecond laser is focused tightly on the tip apex. © 2010 EDP Sciences.

The basic helix–loop–helix (bHLH) transcription factors are one of the largest families of gene regulatory proteins and play crucial roles in genetic, developmental and physiological processes in eukaryotes. Here, we conducted a survey of the Sus scrofa genome and identified 109 putative bHLH transcription factor members belonging to super-groups A, B, C, D, E, and F, respectively, while four members were orphan genes. We identified 6 most significantly enriched KEGG pathways and 116 most significant GO annotation categories. Further comprehensive surveys in human genome and other 12 medical databases identified 72 significantly enriched biological pathways with these 113 pig bHLH transcription factors. From the functional protein association network analysis 93 hub proteins were identified and 55 hub proteins created a tight network or a functional module within their protein families. Especially, there were 20 hub proteins found highly connected in the functional interaction network. The present study deepens our understanding and provided insights into the evolution and functional aspects of animal bHLH proteins and should serve as a solid foundation for further for analyses of specific bHLH transcription factors in the pig and other mammals. © 2015, Springer-Verlag Berlin Heidelberg.

In this paper, we investigate the global exponential stability of fuzzy cellular neural networks with time-varying delays in the leakage terms and reaction-diffusion terms. By constructing a novel Lyapunov functional and applying inequality technique, we obtain some new sufficient conditions for the existence, uniqueness and global exponential stability of the equilibrium solution. Moreover, an numerical example is provided to demonstrate the feasibility of our method. © 2014 Elsevier B.V.
