Structure alignment could help to find shape similarities between proteins and guide structure classification and fold recognition. Common substructure detection and extraction are especially important, for which could guide the biologist to discover binding site or active site. We represent each segment of alpha-carbon backbone by using dihedral angles and curve moment invariants. Then, local and global structure alignment could be performed by iterative closest point algorithm. Maximum common substructures between a pair of proteins or within a protein could be found. Active sites also could be detected by the proposed algorithm.
Power consumption in scan-based testing is a major concern nowadays. In this paper, we present a new X-filling technique to reduce both shift power and capture power during scan tests, namely LSC-filling. The basic id...

Field programmable gate arrays (FPGAs) are widely used in building systems-on-Programmable-Chips (SOPCs) since they contain plenty of reconfigurable heterogeneous resources providing the facility to implement various intellectual property cores. However, with the shrinking device feature size and the increasing die area, nowadays FPGAs can be deeply affected by the errors induced by electromigration and radiation, which results in challenges of building reliable SOPCs. In this paper, a SOPC implementing a smart 1553B bus node is presented to investigate the challenges and illustrate a feasible approach for building a complex system aimed at high reliability and low recovery latency on a commercial FPGA. First, a general reliability model, the DomainPartition (DP) model, is introduced to formulate the SOPCs which contain multiple alternative configurations proving the fault recovery capability. The assignment of the alternative configurations for maximizing the reliability is then determined according to a first-order optimal solution under the DP framework. Finally, the blind reconfiguration technique is used to reduce the recovery latency. The experiments based on a Monte Carlo simulation approach are carried out to evaluate the reliability and the latency. The obtained results show that higher reliability is attainable with less overhead than the generic triple-modular redundancy method.
This paper proposes a novel method to optimizing H.264 decoding on multi-core processors by exploiting color component level parallelism. Compared with sequential decoding and macro-block level parallelism, the propos...
