In order to prolong the lifetime of wireless video sensor networks (WVSNs), many methods for visual target tracking are proposed to reduce the energy cost of batterypowered video sensor nodes. Focus on reducing the amounts of image data for computation and communication, this paper presents an energy-efficient method for distributed target tracking inWVSNs. The major Contributions of the propo…
A new root-lesion nematode was isolated from sugarcane (Saccharum sinensis Roxb.) in Guangxi Zhuang Autonomous Region, China. Morphology and molecular analyses of rRNA small subunit (SSU), D2D3 expansion domains of large subunit (LSU D2D3) and internal transcribed spacer (ITS) confirmed that this nematode is different from other previously described root-lesion nematodes. Herein it is described…
Purpose – The purpose of this paper is to examine the recent recession in the USA and its impact on libraries. It illustrates how libraries are coping with the fiscal constraints and challenges this economic climate imposes. It seeks to provide timely feedback and best practices from librarians and administrators (mostly academic) regarding measures they are taking and their plans for the …
Background and Aims The cell cycle is controlled by cyclin-dependent kinases (CDKs), and CDK inhibitors are major regulators of their activities. The ICK/KRP family of CDK inhibitors has been reported in several plants, with seven members in arabidopsis; however, the phylogenetic relationship among members in different species is unknown. Also, there is a need to understand how these genes and …
Abstract Asymmetric capacitors composed of carbon electrodes with different pore size distributions (PSD) were constructed in order to study the fundamental relationship between the PSD of positive and negative carbon electrodes and the performance of electric double layer capacitors. The performance of asymmetric capacitors in a non-aqueous electrolyte solution (TEMA·BF4/PC) was found to be …

Abstract. We present a novel method for the fabrication of immobilized polyoxometalate catalysts that directly use a self-assembled polyoxometalate solution without isolation and purification. Specifically, self-assembled [WZn3(ZnW9O34)2]12− catalyst can be selectively immobilized into layered double hydroxides in the presence of undesired anions. The material thus obtained demonstrates h…
Abstract. In order to develop a catalyst with high activity and stability for catalytic wet air oxidation of pollutant dyes at room condition, a new polyoxometalate Zn1.5PMo12O40 with nanotube structure was prepared using biological template. The structure and morphology were characterized using infrared (IR) spectra, UV–vis diffuse reflectance spectra (DR-UV–vis), elemental analyses, X…
Abstract Questions: How can we understand the limitations to plant growth at high altitudes? Our aimwas to test the hypotheses that for alpine grasslands along a large altitudinal gradient in semi-arid regions, plant growth is mainly limited by drought at low altitudes but by low temperature at high altitudes, resulting in a unimodal pattern of biomass and productivity associated with an opti…
Mycobacterium tuberculosis (MTB) infection remains a serious infectious disease worldwide, causing 8.8 million new infections and 1.45 million deaths in 2010. The emergence of drug-resistant strains of MTB poses a significant threat to the control of the disease globally. Multidrugresistant MTB (MDR-TB), defined as being resistant to at least rifampicin (RMP) and isoniazid (INH), and extensivel…
Aims.Understanding the response of farmland weed community assembly to fertilization is important for designing better nutrient management strategies in integrated farmland ecological systems. Many studies have focused on weed characteristics, mainly crop–weed competition responses to fertilization or weed communities alone.However, weed community assembly in association with crop growth is p…
