Subspecies differentiation of Chinese white-toothed shrew (Crocidura rapax) is controversial. In order to clarify the molecular phylogeographic pattern of C. rapax and provide further molecular biological evidence for taxonomy, this study analyzed the Cyt b gene sequences of C. rapax (20 samples) collected from Guizhou Province in China together with Cyt b gene sequences of C. rapax (19 samples) downloaded from GenBank. The phylogenetic tree was divided into three main clades: C. r. rapax, C. vorax, and C. rapax kurodai. The C. r. rapax is divided into Guizhou, Yunnan, southeast Sichuan lineage and central and west Sichuan lineage. The results of genetic distance showed that the greatest genetic distance was between central and west Sichuan lineage of C. r. rapax and C. r. kurodai (0. 1181), followed by between Guizhou, Yunnan, southeast Sichuan lineage of C. r. rapax and C. r. kurodai (0. 1174). The genetic distance between two lineages of C. r. rapax is 0. 0195. A similar geographical patterns was also observed in the median-joining network analysis. The results of median-joining network are consistent with the results of phylogenetic relationships and genetic distance, supporting the view that the sample from Taiwan is a separate species, namely, C. tadae. The C. rapax have no subspecies differentiation in China, and can be divided into Guizhou, Yunnan, southeast Sichuan lineage and central and west Sichuan lineage. Twenty-three haplotypes were found in the 32 samples of C. rapax, and the nucleotide polymorphism was 0. 01285. The analysis of population history suggested that C. rapax has experienced population expansion recently, but it is not a single dramatic expansion. [ABSTRACT FROM AUTHOR]

In order to obtain the ideal electric energy from the photovoltaic grid-connected power generation system, a new H6 topology was designed based on the full-bridge circuit, it could effectively suppress the common mode leakage current. At the same time, QPR grid-connected current control strategy was proposed to solve the problem of steady-state error in traditional PI control and overcome the insufficiency of PR control in the interference of small deviation of grid current in fundamental frequency. In Matlab/Simulink platform, a QPR control simulation model based on the new H6 inverter bridge was established. The experiments prove the accuracy and practicability of the new topology and control strategy proposed, and the design has good engineering value in practical application. [ABSTRACT FROM AUTHOR]

Observational experiment of aircraft wake vortex is the basis of studying the evolution behavior of aircraft wake vortex. Disturbed by the effects of atmospheric environment, the exact observation of aircraft wake vortex in cruising and approaching is challenging. In this paper, the laboratory wake observation method including the wind tunnel and towing tank experiment, and the in-site observation method using laser radar and microwave radar equipment has been discussed. The wind tunnel experiment is able to capture the roll-up, development, fall out of the aircraft wake vortex as well as vortices merging (including merging among the wing tip vortex, flap vortex, horizontal tailplane vortex, jet-flow, etc.), while the towing tank experiment can well capture the evolution behavior of aircraft wake vortex in the extended near field and mid field.In addition, the in-situ observational experiment can well capture the process of evolutionary dissipation of aircraft wake vortices in the atmospheric environment, so it can be served as an important reference for studying the effect of different atmospheric environment on the evolution process of aircraft wake vortices, and further for establishing the dynamic separation standard of aircraft wake vortex.

High mobility group protein B1 (HMGB1) is a highly conserved nuclear and non histone proteins, cell, which is caused by the damage or passive release of apoptotic and necrotic cells, as well as the pathogenic factors and active secretions. It can be released into the extra-cellular space during necrosis of all eukaryotic cells. Besides, more and more evidences have shown that the extracellular HMGB1 may be a very potential underlying inflammatory mediator. It has been reported that HMGB1 could serve as an important inflammatory cytokine through binding with its specific receptors. HMGB1 has effect on the inflammation, and the progression of atherosclerotic lesions. Therefore, HMGB1 may be a therapeutic target for the clinical management of coronary artery inflammatory diseases. [ABSTRACT FROM AUTHOR]
