摘要：
In high-power laser system such as Petawatt lasers, the laser beam can be intense enough to result in saturation of nonlinear refraction index of medium. We present an analytical and simulative investigation of hot image formation in an intense laser beam through a saturable nonlinear medium slab based on Fresnel-Kirchhoff diffraction integral and the standard split-step Fourier method. The analytical results are found in agreement with the simulative ones. It is shown that, hot images can still form in an intense laser beam through a saturable nonlinear medium slab, additionally, the saturable nonlinearity does not change the location of hot images, while may decrease the intensity of hot images, i.e., the intensity of hot images decreases with the saturation light intensity lowering, and can stop to increase with the intensity of the incident laser beam heightening due to saturation of nonlinearity. Moreover, variations of intensity of hot images with the obscuration type and the slab thickness are discussed.

摘要：
Reviewing the history of the development of the industrial revolution,it can be seen every economic crisis had brought the major reshuffle of the industrial structure, and eliminated a number of backward industries and businesses, and gave birth to a number of new industries and enterprises. This paper has studied the order parameter control mechanism about the low-carbon symbiotic evolution of enterprise value network in the "post-crisis era ", On the one hand it further reveals the micro-running mechanism of enterprise value network, on the other hand it provides a theoretical decision-making basis for enterprises and government to ensure low-carbon symbiotic evolution of enterprise value network in the "post-crisis era ".

摘要：
In this paper, we present an approach to recognizing characters in surface mount technology (SMT) product. Firstly, we capture the SMT characters image by a camera. Some feature information which can represent the SMT product character images is extracted.

Spin Hall effect of light;vector beam;spin accumulation
摘要：
We report the demonstration of intrinsic spin Hall effect (SHE) of cylindrical vector beam. Employing a fan-shaped aperture to block part of the vector beam, the intrinsic vortex phases are no longer continuous in the azimuthal direction, and results in the spin accumulation at the opposite edges of the light beam. Due to the inherent nature of the phase and independency of light-matter interaction, the observed SHE is intrinsic. Modulating the topological charge of the vector beam, the spin-dependent splitting can be enhanced and the direction of spin accumulation is switchable.

The operators take in sense of the local fractional operators. The obtained results show the fractal behaviors of heat transfer with non-differentiability.
摘要：
In this paper, we investigate the oscillation of second-order half-linear neutral dynamic equations with distributed deviating arguments. By using the generalized Riccati transformation and the inequality technique, we establish some new oscillatory criteria for all solutions to second-order half-linear neutral dynamic equations being oscillatory on the time scale .

The paper presents a new algorithm for calculating the Assignment Problem. The algorithm based on multi-criteria decision of the PAO (Prioritized Aggregation Operators) principle, which s generate the personnel sorting by using different tasks of the Assignment Problem as the criterion of the PAO. According to the sorting results of personnel, assign task to each individual. This method is simple, and only needs a little calculation without any mathematical modeling. The calculation results show that the algorithm is consistent with Hungary algorithm.
摘要：
In this paper, a compressing and reconstruction method for a noise video based on Compressed Sensing (CS) theory is proposed. At first, the CS theory is presented. Then the noise video is estimated from noisy measurement by solving the convex minimization problem. The video recovery algorithms based on gradient-based method is used to compressing and reconstructing the noise signal. And a compressive sensing algorithm with gradient-based method is proposed. At last, the performance of the proposed approach is shown and compared with some conventional algorithms. Our method can obtain best results in terms of peak signal noise ratio (PSNR) than those achieved by common methods with only a little runtime.

摘要：
In this paper, the high-energy magnetic excitations in cuprate superconductors are studied based on the kinetic energy driven superconducting mechanism. The spin self-energy is evaluated explicitly in terms of the collective charge carrier modes in the particle–hole and particle–particle channels, and employed to calculate the dynamical spin structure factor. Our results show the existence of damped but well-defined dispersive spin excitations in the whole doping phase diagram. In particular, the charge carrier doping has a more modest effect on the high-energy spin excitations, and then the high-energy magnetic excitations retain roughly constant energy as a function of doping, with spectral weights and dispersion relations comparable to those found in the parent compound.

Value network embedding choice of strategic emerging enterprises;Cognitive dissonance;Loss of business performance
摘要：
Under the background of "Internet +", strategic emerging enterprises must make themselves embedded in the enterprise value network to gain sustainable and healthy development, but it is difficult for decision maker to make the embedded choice effective. From the perspective of "cognitive dissonance" and "non-economics", this article analyzed the reasons why the value network embedded option induced the loss of business performance in strategic emerging enterprises and the countermeasures to reduce loss, so as to provide theoretical support and method guidance for reducing the loss.

摘要：
Mono-modified beta-cyclodextrins ligands, L-1 (6-mono-(N-aminoethyl)amino-beta-cyclodextrin) and L-2 (6-mono-(N-(pyridin-2-yl)ethylamino)-beta-cyclodextrin), and their platinum(II) complexes, 1 ([Pt(L-1)Cl-2]center dot 8H(2)O) and 2 ([Pt(L-2)Cl-2]center dot 4H(2)O), were successfully synthesized. As revealed by UV-Vis and CD spectroscopic studies, both complexes mainly adopt a non-intercalative mode with DNA. The interaction between platinum complex 1 and DNA was obviously observed in agarose Gel Electrophoresis. Meanwhile, two ligands L-1, L-2 and platinum complex 2 have no obvious interaction with DNA. The difference interaction between complexes 1, 2 and DNA should be ascribed to their different structures.
摘要：
The properties of fractional Fourier transform of anomalous vortex beams are studied. A new type of analytical expression of fractional Fourier transform for anomolous vortex beams is obtained. The properties of anomolous vortex beams on different fractional Fourier transform planes with different parameters are illustrated. The results show that the anomolous vortex beams always has a doughnut profile, the distribution of intensity on different fractional Fourier transform planes highly depends on the fractional order and the beam parameters, such as the beam order and the topological charge.
