Polyploidization has provided much genetic variation for plant adaptive evolution, but the mechanisms by which the molecular evolution of polyploid genomes establishes genetic architecture underlying species differentiation are unclear. Brassica is an ideal model to increase knowledge of polyploid evolution. Here we describe a draft genome sequence of(More)
Species in the ascomycete fungal genus Cordyceps have been proposed to be the teleomorphs of Metarhizium species. The latter have been widely used as insect biocontrol agents. Cordyceps species are highly prized for use in traditional Chinese medicines, but the genes responsible for biosynthesis of bioactive components, insect pathogenicity and the control(More)
We introduce a plasmonic waveguide system, based on a plasmonic analogue of electromagnetically induced transparency, which supports a subwavelength slow-light mode, and exhibits a small group velocity dispersion. The system consists of a periodic array of two metal-dielectric-metal (MDM) stub resonators side-coupled to a MDM waveguide. Decreasing the(More)
Transfer printing is an exceptionally sophisticated approach to assembly and micro-/ nanofabrication that relies on a soft, elastomeric 'stamp' to transfer solid, micro-/ nanoscale materials or device components from one substrate to another, in a large-scale, parallel fashion. The most critical control parameter in transfer printing is the strength of(More)
AIM To obtain the information of ligand-receptor binding between the S protein of SARS-CoV and CD13, identify the possible interacting domains or motifs related to binding sites, and provide clues for studying the functions of SARS proteins and designing anti-SARS drugs and vaccines. METHODS On the basis of comparative genomics, the homology search,(More)
A reconstruction theory for intensity diffraction tomography (I-DT) has been proposed that permits reconstruction of a weakly scattering object without explicit knowledge of phase information. We investigate the I-DT reconstruction problem assuming an incident (paraxial) spherical wave and scanning geometries that employ fixed source-to-object distances.(More)
We review some of the recent research activities on plasmonic devices based on metal-dielectric-metal (MDM) stub resonators for manipulating light at the nanoscale. We first introduce slow-light subwavelength plasmonic waveguides based on plasmonic analogues of periodically loaded transmission lines and electromagnetically induced transparency. In both(More)
3-n-Butylphthalide (NBP) is a compound extracted from Chinese celery and is used as an anti-hypertensive herbal medicine for treating stroke patients. The aim of this study is to demonstrate the effects and mechanisms of this compound through in vitro and in vivo experiments. Culture experiments were performed by adding hydrogen peroxide (H2O2) to SH-SY5Y(More)
A software obfuscator transforms a program into another executable one with the same functionality but unreadable code implementation. This paper presents an algorithm of multi-stage software ob-fuscation method using improved virtual machine techniques. The key idea is to iteratively obfuscate a program for many times in using different interpretations. An(More)
