Invasive plants affect the composition of native habitats,often triggering the loss of biodiversity(Kuebbing et al.,2014,2016;Wang et al.,2021a,2021b).Hence,understanding the mechanisms that underlie successful biological invasion has become a major issue in invasion *** invasion of one habitat by two or more invasive plants is referred to as co-invasion(Sheppard,2019;Wang et al.,2020,2022;Wei et al.,2020a).The invasional meltdown hypothesis posits that the successful colonization of one invasive plant can create a favorable environment for the successful colonization of a second invasive plant(Simberloff,2006;Green et al.,2011;Kuebbing et al.,2016;Braga et al.,2017).

micro-electro-mechanical system （MEMS） device has the advantages of both electronic system and mechanical system. With the development of MEMS devices for satellite, it is possible to establish much lighter and smaller nanosatellites with higher performance and longer lifecyele. The power consumption of MEMS devices is usually much lower than that of traditional devices, which will greatly reduce the consumption of power. For its small size and simple architecture, MEMS devices can be easily integrated together and achieve redundancy. Launched on April 18, 2004, NS - 1 is a nanosatellite for science exploration and MEMS devices test. A mass of science data and images were acquired during its running. NS - 1 weights less than 25 kg. It consists of several MEMS devices, including one miniature inertial measurement unit（MIMU） , three micro complementary metal oxide semiconductor （CMOS）cameras, one sun sensor, three momentum wheels, and one micro magnetic sensor. By applying micro components based on MEMS technology, NS - 1 has made success in the experiments of integrative design, manufacture, and MEMS devices integration. In this paper, some MEMS devices for nanosatellite and picosatellite are introduced, which have been tested on NS -1 nanosatellite or on the ground.

Background The organization and recanalization of thrombi is a dynamic and complex process. The aim of this research was to study the cotherapeutic effect of stem cell transplantation and gene transfection on chronic venous thrombosis. Methods We constructed a recombinant adenoviral vector carrying the vascular endothelial growth factor 165 （VEGF165） gene by using the pAdEasy system, which was subsequently identified and amplified. Simultaneously, endothelial progenitor cells （EPCs） were isolated from rat bone marrow using Ficoll, cultured in EBM-2MV medium, and identified. Then, the cells were transfected with the recombinant Ad-VEGF165. The EPCs were labeled with 1 ,1＇-dioctadecyl-3,3,3＇,3＇-tetramethylindocarbocyanine （Dil） before transplantation. A rat model of chronic vein thrombosis was developed by partial ligation of the inferior vena cava. The rats were randomly divided into 4 groups （n=25, each）： A, Ad-VEGF165/EPC-transplantation group received 1 ml （10^6） of Ad-VEGF165/EPCs; B, EPC-transplantation group received 1 ml （10^6） of EPCs; C, Ad/EPC-transplantation group received 1 ml （10^6） of Ad/EPCs; D, control group received 1 ml of the transplantation medium. The thrombi and adjacent caval walls were harvested 28 days after transplantation; real-time quantitative polymerase chain reaction was used to detect the expression level of vascular endothelial growth factor （VEGF） mRNA; and western blotting was used to measure changes in VEGF protein expression. Hematoxylin-eosin staining and immunohistochemical staining were performed to detect recanalization. Neovascularization was detected by immunohistochemical staining using the antibody for von Willebrand factor （vWF）, which is a component of endothelial *** capillary density was quantitatively determined by counting the capillaries under a high-power microscope. Results The Ad-VEGF165 was constructed, and bone-marrow-derived EPCs were cultivated and successfully identified. We determined the optimum tran

[ Objective] To explore the effects of FSH （ Follicle-stimulating hormone）, seasons and treatment frequency on super-ovulation in donor goats and to provide necessary data for research about embryo transfer and embryo biotechnology in Yangzhou area. [ Method] Two FSH dosages （240 and 300 I U）, two seasons （April- June and October- December）, and two treatment frequencies （one or two times） were used to induce super-ovulation in goats. [ Result] Both average ovulation point and number of transferable embryos were significantly different between the goats given 240 IU FSH and those given 300 lU FSH （average ovulation point, 10.12 vs 15.55; number of transferable embryos, 8.82 vs 13.15） at the 0.05 level. Both average ovulation point and number of transferable embryos were also significantly different between April -June and October- December （ average ovulation point, 9.05 vs 15.55; number of transferable embryos, 7.05 vs 13.15） at the 0.05 level. Super-ovulation effect was not significantly different between the two treatment frequencies. [ Conduslonl The FSH dosages and seasons have significant impact on super-ovu- lation, but repeat super-ovulation does not have the same impact.

利用群论理论研究16种多环芳烃(polycyclic aromatic hydrocarbons,PAHs)分子振动规律,并对PAHs指纹区特征拉曼峰进行偏振去噪,减少非特征拉曼峰对特征拉曼峰的干扰,增强16种PAHs之间的拉曼辨识度。群论分析发现16种PAHs分别属于Cs,C2v,C2h,D2h点群,四个点群中的A′,A1,Ag,Ag类对称振动属于全对称振动,其余对称振动为非全对称振动,其中全对称振动均具有拉曼活性。Gaussian 09杂化密度泛函理论计算与群论分析相结合,发现16种PAHs全对称振动分布拉曼位移全区域,涵盖16种PAHs基团振动模式;全对称振动产生的波动性小,具有一定的抗外部环境干扰能力,稳定性相对较高,并且其产生的拉曼峰更强。根据全对称振动具有代表性、稳定性、显著性的特征,本文将16种PAHs的全对称振动作为特征拉曼振动。此外,研究发现,拉曼偏振效应与振动模对称性直接相关,拉曼光谱的偏振效应具有增强PAHs特征拉曼峰、降低PAHs非特征峰强度的作用。16种PAHs通过拉曼光谱的偏振效应选择性调节作用后,PAHs特征拉曼峰信噪比可提高6.52%~182%,说明利用拉曼偏振效应去除非特征拉曼峰的作用显著,可有效降低特征峰的噪声干扰。因此,所建立的基于群论的PAHs分子拉曼偏振去噪方法可以改善其拉曼光谱信号质量,提高PAHs同步拉曼光谱分析效率,为实现16种PAHs同步拉曼光谱检测提供了理论依据。
