coral transplantation is considered as one of the major tools to increase coral abundance for degraded coral *** investigate the effects of various methods and coral species in transplantation, coral fragments（n=902） of five coral species were transplanted by four methods at Luhuitou, the Sanya Bay, Hainan Province, china, where the reef has been over-exploited and is still threatened by human activities and natural disasters. Ten months after the transplant, the average survivorship of the transplanted corals was 45.5%. Methodologies had different effects on the transplanted corals, but none of them was efficacious for all coral species. Methodology could not change the decreasing trend for Montipora foliosa and Acropora hyacinthus, although it did slow down their decline. All transplants of A. hyacinthus and M. foliosa had high mortalities and significant decrease on survival area, while Porites andrewsi and Galaxea fascicularis had lower mortalities and partial mortalities. Only one method had significant effect on increasing survival area of G. fascicularis, same as P. andrewsi. Out of the five transplanted coral species, Pocillopora damicornis was the only species that had living tissue area increase in all applied methods, while the others had decreased live tissue area in one or more methods. The results of this study suggested that performing coral transplantation in a highly threatened area was not efficient unless the threats were diminished or erased. Moreover, proper species selection for coral transplantation is crucial, especially in a disturbed environment. Methodology, although having limited effects on improving results of coral transplantation, cannot compensate the maladjustment of vulnerable species to the stresses on the Luhuitou Reef. coral transplantation on Luhuitou Reef should not be performed unless the stresses are under controlled,and corals with good tolerance to the environment should be considered first.

Acute epiploic appendagitis at the tip of the appendix mimicking acute appendicitis: A rare case report with literature review

引用

World Journal of Gastrointestinal Surgery 2019年第8期11卷 342-347页

作者： Kai huang Abdul Waheed william Juan Subhasis Misra cristiano Alpendre Stephen Jones Brandon Regional Hospital HCA West Florida Division/USF Consortium

BAcKGROUND Acute epiploic appendagitis of the appendix (AEAA) is a rare self-limiting inflammatory disorder of the epiploic appendages (EA) close to the vermiform appendix, which often times mimicking the presentation of acute appendicitis (AA). To date, very few cases of AEAA have been reported. We report a case of a 52-year old man with the clinical suspicion of AA, but post-operative specimen examination confirmed AEAA as the final diagnosis. cASE SUMMARY A 52-year-old morbidly obese man presented to the emergency department with a 1-d history of the right lower quadrant (RLQ) abdominal pain. Physical examination revealed localized RLQ tenderness mimicking AA. The computed tomography abdomen was inconclusive, and a decision was made to perform laparoscopic appendectomy (LA). During the LA, an infarcted epiploic appendage at the tip of appendix and adherent to the abdominal wall was found, which was entirely excised. Final pathology showed congested and hemorrhagic epiploic appendage without any accompanied acute inflammatory changes in the wall of the appendix. Postoperative course was uneventful and he was doing well at seven months follow-up. cONcLUSION The possibility of AEAA should be considered in patients clinically suspected of having AA. Surgery is considered for those refractory to conservative management, with inconclusive diagnosis or develop complications at presentation.

Acta Mathematica Scientia 1987年第2期7卷 197-205页

作者：冯振兴,T.c.huang Wuhan University Wisconsin University Wisconsin University

The coupled problem means fluid-structure interaction widely encountered in aviation, offshore and nuclear engineerings. The coupling method here means the combination of finite and boundary elements(FE/BE)to improve the computational effciency considerably. In this paper, a general math. Model for simulation of the wetted structure dynamic response to inter/external fluid flow is presented. In particular, the various boundary conditions for fluid region are treated sophsticatodiy. In this way, only the displacement and pressure remain to be the independent variables so that both computer cost and accuracy could be improved. The FORTRAN program package of this model has been compiled on #Univac-1110 in Madison (MAcc), USA, and on #M340S computer in Wuhan University, china. As a first approximation, in this paper a 2-D example for the ship-wave interaction analysis is illustrated.

Ground control monitoring of retreat room–and–pillar mine in central Appalachia

International Journal of Mining Science and Technology 2017年第1期27卷 65-69页

作者： Erik c.Westman Ryan J.Molka william J.conrad Mining and Minerals Engineering Department Virginia TechBlacksburgVA 24061USA

In order to study pillar and overburden response to retreat mining, a ground control program was conducted at a central Appalachian Mine. The program consisted of several monitoring methods including a seismic monitoring system, borehole pressure cells in the pillars, and time-lapse photogrammetry of the pillar ribs. Two parallel geophone arrays were installed, one on each side of the panel with the sensors mounted 3 m into the roof. A total of fourteen geophones recorded more than 5000 events during the panel retreat. A MIDAS datalogger was used to record pressure from borehole pressure cells(BPcs)located in two adjacent pillars that were not mined during retreat. A series of photographs were taken of the pillars that had the BPcs as the face approached so that deformation of the entire rib could be monitored using photogrammetry. Results showed that pillar stability and cave development were as expected. The BPcs showed an increase in loading when the face was 115 m inby and a clear onset of the forward abutment at 30 m. The photogrammetry results displayed pillar deformation corresponding to the increased loading. The microseismic monitoring results showed the overburden caving inby the face, again as expected. The significance of these results lies in two points,(1) we can quantify the safe manner in which this mine is conducting retreating operations, and(2) we can use volumetric technologies(photogrammetry and microseismic) to monitor entire volumes of the mine in addition to the traditional point-location geotechnical measurements(BPcs).

chinese Science Bulletin 2001年第20期46卷 1756-1760页

Both of the oceanographic research by using altimetry and the application of InSAR of ERS-2 satellite need the precise ephemerides of the satellite. In this note, the ERS-2 orbit is precisely determined by using SLR and PRARE observations to take advantage of the high accuracy of SLR and the widespread data coverage of PRARE. Based on the software system SODS-VcE established by us, the ERS-2 orbits in 1997 are calculated. The evaluation from tracking data fits, endpoint consistency of orbital arcs and comparison with independent orbit implies an orbit accuracy of 5-6 cm in radial component which can satisfy the requirement of being better than 10 cm in oceanographic research by altimetry, being less than 20 cm in cross-track component which can meet the requirement of InSAR. In orbit computation, the method of variance component estimation is employed to weight the SLR, PRARE range and Doppler measurements properly. The results indicate that the application of the method can improve the computation

cobalamin-dependent radical S-adenosyl-L-methionine protein functions with a partner to successively methylate tricyclic indole alkaloid for chuangxinmycin maturation and derivatization

引用

Science china chemistry 2025年第1期 308-316页

作者： Sili Wang Jiancheng huang Yanan Du Wei huang Yufeng Xue Xiaokun Xu Guannan Zhong Yuanyuan Shi Bin Hong Xiaoying Bian Wen Liu State Key Laboratory of chemical Biology Shanghai Institute of Organic Chemistry University of Chinese Academy of SciencesChinese Academy of Sciences State Key Laboratory of Microbial Technology Shandong University National Health commission (NHc) Key Laboratory of Biotechnology for Microbial Drugs Institute of Medicinal BiotechnologyChinese Academy of Medical Science & Peking Union Medical College

cobalamin(cbl)-dependent radical S-adenosyl-L-methionine(SAM) proteins constitute the largest collection of the radical SAM superfamily that has hundreds of thousands of individual members. Many of these proteins are involved in the biosynthesis of pharmaceutically important natural products to catalyze chemically demanding reactions. In the biosynthetic pathway of chuangxinmycin(cXM), a unique indole alkaloid antibiotic with potent anti-infective activity, functionalization of the characteristic thiopyrano[4,3,2-cd]indole scaffold by regio-and stereoselective c3-methylation is believed to rely on a cbl-dependent radical process, which, however, remained to be reconstituted biochemically. We here report the dissection of this enzymatic process, which requires the incorporation of cxm8, a cbl-dependent radical SAM protein, with cxm9, a DUF5825family protein that shares no homology to any proteins of known functions. cxm8 and cxm9 function together by forming an unexpected heterodimeric complex that selectively catalyzes c3-methylation of the tricyclic indole-S-hetero ring system in a successive manner, achieving cXM and a recently identified, c3-dimethylated congener. Detailed biochemical characterization,isotope labeling, structural simulation and bioinformatics analysis rationalized the catalysis of the cxm8/cxm9 complex and particularly the necessity of the DUF5825 protein for c3-methylase activity. This is the first example that a cbl-dependent protein acts with a partner to exhibit radical SAM activity.
