Nowadays the modular multiplications in many kinds of smartcards are utilized Montgomery's algorithm modular multiplier, so traditional SPA to RSA becomes invalid. An improved attack method is proposed based on SPA which just depends on the fact that there exist some subtle differences in each loop during the operation of cd mod n. At same time, compared with the traditional SPA, it doesn't need to select the clear text or some known message. Using this method, attacks can easy to discover the mode of RSA implementation and extract the bits of decryption key just based on a few collected traces. From the real attack test on several main kinds of smartcard, the private keys of RSA stored inside can be analyzed successfully.

Remote state preparation is increasingly becoming attractive in recent years, people have already started theoretical and experimental research, and have made valuable research results. Recently, a scheme for probabilistic remote preparation of a general two-qubit state was proposed （Wang Z Y in Quantum Inf Process. 11：1585, 2012））. In this paper, we present a modified scheme for probabilistic remote preparation of a general two-qubit state. To complete the scheme, the new and feasible complete orthogonal basis vectors have been introduced. Compared with the previous schemes, the advantage of our schemes is that the total success probability of remote state preparation will be greatly improved. The probability of success regarding this scheme is calculated in both general and particular cases. The results show that the success probability of remote state preparation can be improved a little. However, in certain special cases, the success probability of preparation can be greatly improved. In special cases, the success probability of preparation can be improved to 1. The security analysis of the scheme is provided in details.

Processor specialization has become the development trend of modern processor industry. It is quite possible that this will still be the main-stream in the next decades of semiconductor era. As the diversity of heterogeneous systems grows, organizing computation efficiently on systems with multiple kinds of heterogeneous processors is a challenging problem and will be a normality. In this paper, we analyze some state-of-the-art task scheduling algorithms of heterogeneous computing systems and propose a Degree of Node First (DONF) algorithm for task scheduling of fine-grained parallel programs on heterogeneous systems. The major innovations of DONF include: 1) simplifying task priority calculation for directed acyclic graph (DAG) based fine-grained parallel programs which not only reduces the complexity of task selection but also enables the algorithm to solve the scheduling problem for dynamic DAGs;2) building a novel communication model in the processor selection phase that makes the task scheduling much more efficient. They are achieved by exploring finegrained parallelism via a dataflow program execution model, and validated through experimental results with a selected set of benchmarks. The results on synthesized and real-world application DAGs show a very good performance. The proposed DONF algorithm significantly outperforms all the evaluated state-of-the-art heuristic algorithms in terms of scheduling length ratio (SLR) and efficiency.

The physical stability of solid-liquid fuel is a factor that needs to be considered for fuel product practicability for storage and transportation. To determine the Influence of liquid bridge force on physical stability, two detection devices were designed. The laws obtained from microscopic experiments are used to verify the physical stability of fuel under different component ratios. The liquid bridge force is found to increase with the droplet volume. Multiliquid bridges above one critical saturation can generate significant resultant forces compared to single-liquid bridges of the same volume. There exist four states of solid-liquid mixed fuel with increasing liquid saturation rate. The liquid bridge force between the solid and liquid plays a dominant role in the physical stability of the first three states. There may be two stages involved in the stratification process for state 4 fuel, and the liquid viscosity is another factor that cannot be ignored. In the process of selecting a fuel ratio, a larger liquid bridge force between the components can be obtained by properly improving the wetting effect so that the fuel shows better physical stability.

Proline plays an important role in regulating synaptic neurotransmission in both mammalian and insect nervous systems. The full-length complementary DNA sequences encoding the proline transporter gene （CsProT） and its alternative spliced transcript （CsProT-ST） were cloned from the striped stem borer （SSB）, Chilo suppressalis, one of the most important rice pests in Asia. The comparison of amino acid sequences showed that CsProT is highly similar to the proline transporter isolated from Manduca sexta （MasProT）. The developmental changes of the relative messenger RNA expression levels of CsProT and CsProT-ST genes were examined in SSB. The expression level of CsProT-ST is much higher than that of CsProT in all developmental periods, suggesting that the Y-end spliced variant is the major transcript instead of CsProT. The highest ex- pression level of both genes in the pupal stage means that proline may be involved in some unclear functions in the metamorphosis from pupa to adulthood.

Circulating tumor cells(CTCs),recognized as intermediaries between primary and distant lesions,are key to understanding the mechanisms of cancer *** the dissemination of tumor cells in the circulatory system is a spatially and temporally dynamic process,CTCs can logically be assumed to be a population of cells displaying both spatial and temporal heterogeneity^(1).Prior studies have revealed substantial temporal heterogeneity in CTC phenotypes during anti-cancer treatments^(2,3).However,current knowledge of CTCs is derived mostly from peripheral venous blood;thus,only a snapshot of the entire circulatory process has been determined,and much more remains to be understood.
