Objectives: In 2015, the Mw 7.8 earthquake in Nepal caused landslides and seriously impacted Nepal and its surrounding areas. Methods: In this paper, the Sindhupalchowk area, which is close to the epicenter of the earthquake, is selected as the study area. First, based on the L-band ALOS-2 and C-band Sentinel-1A synthetic aperture radar data, the detection and identification of post-earthquake landslides are carried out by using stacking-InSAR(interferometric synthetic aperture radar) technology. Second, the two-dimensional time series deformation characteristics of a typical landslide are obtained by combining the ascending and descending orbit data and multi-dimensional small baseline subset-InSAR technology. Results: Combined with optical images, 14 hidden points of landslide are delineated. The main deformation of the typical landslide occurs in the horizontal east-west direction, and the maximum deformation rate is −69 mm/a. Conclusions: By analyzing the trend and periodic term deformation signals in time series of the typical landslide, it is found that the earthquake has a significant acceleration effect on the landslide movement, and the increase of rainfall makes the landslide displacement show a periodic change from August to November every year. This paper can provide a reference for post-earthquake landslide monitoring re⁃ search. [ABSTRACT FROM AUTHOR]

Destructive disasters can cause enormous harm and losses, and due to a lack of information for a certain period of time after the disaster, it is extremely detrimental to understanding the disaster situation and disaster relief. In order to obtain timely collapse and damage information of buildings, roads, bridges, reservoirs and other important ground objects in disaster areas, a method for automatically identifying and annotating the differences in remote sensing images before and after disasters has been proposed. Firstly, Gaussian noise was removed from time-series remote sensing images using block matching 3D (BM3D) method, and then image registration was performed using scale invariant feature transform (SIFT) method. The edge information of important ground objects in different areas was obtained by using Wv_Canny edge detection method for difference images. Finally, the important ground objects that have changed were identified and annotated. The experimental results of remote sensing image were compared according to the change area of the building, the correct rate is 78% ~ 79%, the false detection rate is 21% ~ 22%, and there is no missed detection rate. Simulation experiment and actual remote sensing image processing show that the proposed method can effectively identify and mark the difference areas of important ground objects such as buildings, which is conducive to timely understanding and rescue of destructive ground objects after disaster.

目的：探讨多层螺旋CT（MSCT）增强扫描在胃癌术前TNM分期评估中的价值。方法对78例胃癌患者行MSCT三期增强扫描，以胃癌切除术后病理检查为金标准，对比分析MSCT增强扫描评估胃癌TNM分期的准确性。结果 MSCT增强扫描与术后病理检查一致性较高，T1～T4分期诊断符合率为83．3％；N0～N3诊断符合率为84．6％；M0～M1分期诊断符合率为91．0％。结论 MSCT增强扫描对评估胃癌术前TNM分期有较高的准确性，对胃癌治疗方案的选择有指导作用。 [ABSTRACT FROM AUTHOR]

The active components of Lepidium apetalum, cardiac glycosides have been well studied both chemically and pharmacologically, but little is known about the cardiac glycosides biosynthesis pathway. Using cultivated seedlings as material, the transcriptome data of Lepidium apetalum, designing specific primers and using PCR method, an open reading frame (ORF) of key enzyme 2-C-methylerythritol-4-phosphate cytidylyltransferase (MCT) gene which involved in MEP pathway was isolated and named as LaMCT (GenBank accession no. KT832554). The sequence analysis and prokaryotic expression were also performed. Sequence analysis showed that LaMCT has an ORF of 912 bp, which encoded a protein of 304 amino acid residues. Subcelluar localization and conserved domain analysis indicated that LaMCT protein located in chloroplast had no signal peptide and transmembrane domain, but had a isoprenoid synthase conserved domain. Phylogenetic analysis revealed that LaMCT protein showed the highest homology, 94% similarity, with MCT protein from Arabidopsis thaliana. Through the construction of pET-32a-LaMCT vector, the recombinant LaMCT protein was successfully expressed in Escherichia coli BL21 (DE3) cells. Finally, the recombinant LaMCT protein was purified through Ni2+ affinity chromatography. The LaMCT gene was cloned from L. apetalum, and the stable prokaryotic expression system of pET-32a-LaMCT was constructed. This study will provide some basic information for the further antibody preparation of LaMCT protein and would be helpful in functional research of LaMCT gene involved in cardiac glycosides biosynthesis pathway.

Aiming at the problem of waste of weapon resources in traditional weapon target assignment (WTA)，and to realize the maximum benefit of target and network attacks and the minimum consumption of weapons, we establish a multi-objective WTA model, which takes the damage probability constraint into consideration. We improve the standard quantum immune clonal multi-objective optimization algorithm (QICMOA)，introduce the chaos mechanism, and repair the infeasible solutions. We also make improvement for the search strategy and diversity maintaining strategy and design an improved QICMOA. Simulation experiments verify the correctness of the model and the superiority of the algorithm. Compared with the traditional QICMOA, the performance of the new algorithm is improved by 23% on average. [ABSTRACT FROM AUTHOR]
