As one of the most significant characteristics of human cell, subcellular localization plays a critical role for understanding specific functions of mammalian proteins. In this study, we developed a novel computational protocol for predicting protein subcellular locations from microscope cell images in human reproductive tissues. Experiments are performed on a benchmark dataset consisting of 7 major subcellular classes in human reproductive tissues collected from Human Protein Atlas database. We first separated protein and DNA staining in the images with both linear and nonnegative matrix factorization separation methods;then we extracted protein multi-view texture features including wavelet haralick and local binary patterns;finally based on the selected important feature subset achieved by feature selection technique, we constructed ensemble classifier based on support vector machines for predictions. Our experimental results show that 84% accuracy can be achieved through current system, and when only considering the most confident classifications, the accuracy can rise to 98%. © Springer-Verlag 2013.

Improving the maximum transmission distance of four-state continuous-variable quantum key distribution by using a noiseless linear amplifier

引用

Physical Review A 2013年第6期87卷 062311-062311页

作者： Bingjie Xu Chunming Tang Hui Chen Wenzheng Zhang Fuchen Zhu Science and Technology on Security Communication Laboratory 610041 Cheng Du China Institute of Southwestern Communication 610041 Cheng Du China School of Mathematics and Information China West Normal University 637002 Nanchong China

A modified four-state CVQKD protocol is proposed to increase the maximum transmission distance and tolerable excess noise in the presence of Gaussian lossy and noisy channel by using a noiseless linear amplifier (NLA). An ideal NLA with gain g can increase the maximum admission losses by 20log10g dB. Further, the imperfections in a practical NLA, such as the finite detection efficiency and imperfect single-photon source, are included in consideration.

The major challenge in area stereo matching algorithms is to find appropriate window size and shape. Phase congruency is robust to noise and can reflects the gray changes. With these benefits, the paper first detects image and determines pixels characteristics according to phase congruency. Then, different window will be used to matching according to different feature pixels. After using cost function which combined with non-parametric measure and gray value, the final disparity map will be obtained. The result of experiment indicates that the algorithm can generates more accurate disparity map. © (2013) Trans Tech Publications, Switzerland.

Procedia Computer science 2013年 17卷 523-529页

作者： Kefu Xu Wenke Cui Yue Hu Li Guo Institute of Information Engineering Chinese Academy of Sciences National Engineering Laboratory for Information Security Technologies Beijing 100093 China School of Computer & Communication Engineering University of Science & Technology Beijing Beijing 100083 China

Approximate string matching is one of the most important technologies in the field of computer science, and it is widely used in network security, computational biology, information retrieval, spelling correction and other areas. In these areas, there are huge amounts of data need to be addressed in time. So it requires a high- performance string matching algorithm. At the same time, with the introduction of Compute Unified Device Architecture (CUDA), the general-purpose computing of Graphic Processing Unit (GPU) extended to more applications. This paper proposed a bit-parallel multiple approximate string match algorithm, and developed a GPU implementation which achieved speedups about 28 relative to a single-thread CPU code.

This paper addresses the power con- trol problems of Cognitive Radio （CR） trader transmission power and interference tempera- ture constraints. First, we propose the interfer- ence constraint which ensures that the Quality of Service （QoS） standards for primary users is considered and a non-cooperative game power control model. Based on the proposed model, we developed a logical utility function based on the Signal-to-Interference-Noise Ratio （S/NR） and a novel algorithm network power control. that is suitable for CR Then, the existence and uniqueness of the Nash Equilibrium （NE） in our utility function are proved by the principle of game theory and the corresponding optimi- zations. Compared to traditional algorithms, the proposed one could converge to an NE in 3-5 iterative operations by setting an appropriate pricing factor. Finally, simulation results ver- ified the stability and superiority of the novel algorithm in flat-fading channel environments.

Traditionally, sea cucumber production relies heavily on human labors which results in low production efficiency and inability to meet the demands of a rapidly growing market. To address this problem, this paper brings the idea of cyber physical systems (CPS) into aquatic areas. This paper provide a detailed analysis of the theory and characteristics of CPS along with its practical significance, and construct a physical information fusion system for sea cucumber production. The system is designed according to the CPS architecture, which includes the environmental monitoring subsystem, the information processing and transmission subsystem, the process control subsystem and the remote control center. In accordance with the characteristics of interaction between physics and information, this paper models and verifies the physical process by using the theory of automata, which ensures the reliability of the overall system. The deployment of the main parts of the system has been completed. The observation data indicates that, the system can be used to effectively monitor sea cucumber production. The system also has good scalability. Through in-depth cooperation with experts in the field, we believe it can be extended to be used in many other applications in water environment. © 2013 ISCAS.

Cryptographic approaches are vulnerable to impersonation attacks when nodes become compromised. Meanwhile, trust-based judgment and confirmation of cluster heads in WSN imposes higher communication cost. Trust management and authentication on cluster heads in WSN are essential in research on the mechanisms of secure data aggregation at present. In this paper, an energy attenuation model is adopted to describe event sensing in a kind of WSNs. Approximate evaluation on distance between occurring event and nodes within a cluster is achieved in case the location of the event is not known. Distribution properties of data points with clustering characteristics based on fitting curve construction are theoretically analyzed. In addition, the mechanism on trust authentication on cluster heads is also refined. Experimental results show that the proposed mechanism has much better performance on fitting accuracy and malicious CH recognition than previous works. © 2013 ISCAS.

Unified and Complete Point Addition Formula for Elliptic Curves

引用

电子学报(英文版) 2012年第2期21卷 345-349页

作者： ZHANG Lijun WANG Kunpeng WANG Hong Science and Technology on Communication Security Laboratory Chengdu 610041 China State Key Laboratory of Information Security GUCAS Beijing 100049 China

As is well known, the unified point addition formula is useful for resisting side channel attacks in elliptic curve cryptography. Furthermore, if the unified formula is complete, which means it is valid for any two points, then there are no exceptional cases to be described particularly. This feature is especially preferable for elegant codes of elliptic crypto-algorithms. Therefore, the unified and also complete point addition formula can provide the advantage for good security and convenient implementation. In this paper, we exploit sufficient and necessary condition for the existence of unified and complete point addition formula on several known elliptic curve models such as Weierstrass cu- bics, Jacobi quartics, Edwards curves, etc.. Moreover, we study another form of elliptic curves called Selmer curves. For practical application, we finally give some numerical examples of cryptographic secure Selmer curves.

Bacteriorhodopsin (bR) is a light-sensitive protein which has a proton-pump function, and is found in the cell membrane of Halobacterium salinarum inhabiting the salt lake. Optical excitation of bR at an electrode-electrolyte interface generates differential photocurrents while an incident light is turned on and off. This unique functional response is similar to that seen in retinal neurons. This paper describes the fabrication and evaluation of the dip-coated bR thin films, photocurrent characteristics, and biomimetic artificial retinas with the bR thin films.
