A scheme of probabilistic teleportation was proposed. In this scheme, we took a six-qubit nonmaximally cluster state as the quantum channel to teleport an unknown three-qubit entangled state. Based on Bob’s three times Bell state measurement (BSM) results, the receiver Bob can by introducing an auxiliary particle and the appropriate transformation to reconstruct the initial state with a certain probability. We found that, the successful transmission probability depend on the absolute value of coefficients of two of six particle cluster state minimum. © 2014, Springer Science+Business Media New York.

The computation of image segmentation has become more complicated with the increasing number of thresholds, and the option and application of the thresholds in image thresholding fields have become an NP problem at the same time. The paper puts forward the modified discrete grey wolf optimizer algorithm (MDGWO), which improves on the optimal solution updating mechanism of the search agent by the weights. Taking Kapurs entropy as the optimized function and based on the discreteness of threshold in image segmentation, the paper firstly discretizes the grey wolf optimizer (GWO) and then proposes a new attack strategy by using the weight coefficient to replace the search formula for optimal solution used in the original algorithm. The experimental results show that MDGWO can search out the optimal thresholds efficiently and precisely, which are very close to the result examined by exhaustive searches. In comparison with the electromagnetism optimization (EMO), the differential evolution (DE), the Artifical Bee Colony (ABC), and the classical GWO, it is concluded that MDGWO has advantages over the latter four in terms of image segmentation quality and objective function values and their stability.

Based on adaptive control and Lyapunov stability theory, a novel adaptive Generalized Combination Complex Synchronization (GCCS) scheme is proposed for nonidentical hyperchaotic complex systems with unknown parameters. Firstly, the definition of GCCS is presented, and synchronization of drive-response systems is transformed to the zero solution analysis of the error dynamical system. Secondly, a nonlinear feedback controller and parameter update laws are theoretically designed, wherein error feedback gains are introduced to control synchronization speed. Finally, GCCS among the hyperchaotic complex Lorenz system, complex Chen system, and complex Lü system is carried out to verify the correctness and effectiveness of the proposed scheme by numerical simulation. © 2016, Science Press.

The aim of this paper is to introduce and investigate a novel complex Lorenz system with a flux-controlled memristor, and to realize its synchronization. The system has an infinite number of stable and unstable equilibrium points, and can generate abundant dynamical behaviors with different parameters and initial conditions, such as limit cycle, torus, chaos, transient phenomena, etc., which are explored by means of time-domain waveforms, phase portraits, bifurcation diagrams, and Lyapunov exponents. Furthermore, an active controller is designed to achieve modified projective synchronization (MPS) of this system based on Lyapunov stability theory. The corresponding numerical simulations agree well with the theoretical analysis, and demonstrate that the response system is asymptotically synchronized with the drive system within a short time. © 2015 by the authors.

In this paper, generalized synchronization (GS) is extended from real space to complex space, resulting in a new synchronization scheme, complex generalized synchronization (CGS). Based on Lyapunov stability theory, an adaptive controller and parameter update laws are designed to realize CGS and parameter identification of two nonidentical chaotic (hyperchaotic) complex systems with respect to a given complex map vector. This scheme is applied to synchronize a memristor-based hyperchaotic complex Lü system and a memristor-based chaotic complex Lorenz system, a chaotic complex Chen system and a memristorbased chaotic complex Lorenz system, as well as a memristor-based hyperchaotic complex Lü system and a chaotic complex Lü system with fully unknown parameters. The corresponding numerical simulations illustrate the feasibility and effectiveness of the proposed scheme. © 2016 Wang et al.

S5 0716+714 is a well-studied BL Lac object in the sky. Verifying the existence of correlations among the flux variations in different bands serves as an important tool to investigate the emission processes. To examine the possible existence of a lag between variations in different optical bands on this source, we employ a discrete correlation function analysis on the light curves. In order to obtain statistically meaningful values for the cross-correlation time lags and their related uncertainties, we perform Monte Carlo simulations called 'flux redistribution/random subset selection'. Our analysis confirms that the variations in different optical light curves are strongly correlated. The time lags show a hint of the variations in high frequency band leading those in low frequency band of the order of a few minutes. © Astronomical Society of Australia 2010.

Imidazole is a fundamental building unit possessing a conjugated five-membered ring system with two N-donor coordination sites. The parent imidazole nucleus can be derivatized to three types of compounds at the 1-, 2-, or 4-positions, generating 1, 2, or 4-imidazole-containing ligands, or can be endowed with other functional groups to form multi-functional ligands. Imidazole and its derivatives have been widely employed as excellent candidates for targeted metal-organic frameworks (MOFs) in the domain of coordination chemistry. Moreover, recent reports show a boom in exploratory synthesis using imidazole derivatives to construct novel MOFs due to their distinct characteristics. In consideration of the rapidly growing research on imidazole ligands, herein, we would like to highlight the recent advances in the rational design of MOFs based on imidazole derivatives from our and other research groups; we would also like to provide new insights into the rational design of organic tectons and the construction of these advanced crystalline materials with desirable properties and functionalities. © 2016 The Royal Society of Chemistry.

In this paper, the dynamics of tripartite entanglement via π-tangle in independent non-Markovian environments is investigated. The results indicate that the π-tangle vanishes periodically as decoherence time increases with a damping of its revival amplitude due to the memory of the non-Markovian environments. In addition, we present a scheme to protect entanglement of W state from non-Markovian environments by means of the quantum partially collapsing measurements. It is worth mentioning that our scheme is a successful protection for the tripartite quantum system and the effect is better for the larger measurement strength, while the stronger decoherence suppression induces smaller success probability. © 2016, Springer Science+Business Media New York.

The food industry is more and more in need of importing and absorption new technologies. Focusing on all the possible issues of contradiction and difficulty to improve the digestion and absorption of novel manufacturing technology, a set of customized dynamic quantitative evaluation models were put forward that made it easy to model and supervise the usages, digestion and absorption of novel manufacturing technology in food enterprises. According to the proposed set of evaluation models, anyone could comprehensively analyze the food enterprises' technology import, digestion and absorption and even re-innovation capabilities from many aspects. The models and strategy discussed here are highly operable and objectively profitable to insure the dynamic evaluation of the digestion and absorption of technology imported in food enterprises. © Maxwell Scientific Organization, 2015.

In Seleskovitch's interpretive theory of translation, the construct of sense is the core of the triangular process of translation. Taking this as a starting point, the present paper argues that the construct of sense is only part of the truth of the reality in translation. The translator in a translation not only constructs sense at the stimulus of the source text, but also makes meaning for the readers in the target language, using the target text as a stimulus. Thus the process of translation is divided into two steps: the construct of sense and the make of meaning. © 2015 IEEE.
