A class of deterministic interleavers for turbo codes (TCs) based on permutation polynomials over /spl Zopf//sub N/ is introduced. The main characteristic of this class of interleavers is that they can be algebraically designed to fit a given component code. Moreover, since the interleaver can be generated by a few simple computations, storage of the(More)
In recent years, a lot of efforts have been made in conformational epitope prediction as antigen proteins usually bind antibodies with an assembly of sequentially discontinuous and structurally compact surface residues. Currently, only a few methods for spatial epitope prediction are available with focus on single residue propensity scales or continual(More)
Shadows, the common phenomena in most outdoor scenes, bring many problems in image processing and computer vision. In this paper, we present a novel method focusing on extracting shadows from a single outdoor image. The proposed tricolor attenuation model (TAM) that describe the attenuation relationship between shadow and its nonshadow background is derived(More)
Detection of the visual salient regions is a challenging and significant problem in computer vision. In this paper, we propose a boundary based prior map and a soft-segmentation based convex hull to improve the saliency detection. First, we present to utilize the boundary information to obtain the coarse prior map. Then a convex hull improved by(More)
Keywords: Line-of-sight guidance Ship path following Model predictive control a b s t r a c t This paper presents a model predictive control (MPC) for a way-point tracking of underactuated surface vessels with input constraints. A three-degree-of-freedom dynamic model of surface vessels has been used for the controller design. In order for the control(More)
In this paper, we propose a Connective-driven Dependency Tree (CDT) scheme to represent the discourse rhetorical structure in Chinese language, with elementary discourse units as leaf nodes and connectives as non-leaf nodes, largely motivated by the Penn Discourse Treebank and the Rhetorical Structure Theory. In particular, connectives are employed to(More)
Laccases are strong oxidizing enzymes that oxidize chlorinated phenols, synthetic dyes, pesticides, polycyclic aromatic hydrocarbons as well as a very wide range of other compounds with high redox potential. Based on the bias of genetic codons between fungus and yeast, we synthesized a laccase gene GlLCCI, originated from Ganoderma lucidum using optimized(More)
—Content Distribution Networks have been attracted a great deal of attraction in recent years. Replica placement problems (RPPs) as one of the key technologies in the Content Distribution Networks have been widely studied. In this paper, we propose an optimization model with server storage capacity constraints for the RPPs. Furthermore, part of the(More)
ZigBee is the new standard that has been developed for low cost, low data rate and low power consumption wireless network. And mesh is a type of network architecture. This paper provides a brief overview of the available IEEE 802.15.4 topologies, and then delvesing the mesh topology, describing its advances, disadvantages and application, and presents a(More)
UNLABELLED First-generation EGFR tyrosine kinase inhibitors (EGFR TKI) provide significant clinical benefit in patients with advanced EGFR-mutant (EGFRm(+)) non-small cell lung cancer (NSCLC). Patients ultimately develop disease progression, often driven by acquisition of a second T790M EGFR TKI resistance mutation. AZD9291 is a novel oral, potent, and(More)
