2Development and case study of a science-based software platform to support policy making on air quality显示文摘This article describes the development and implementations of a novel software platform that supports real-time, science-based policy making on air quality through a user-friendly interface. The software, RSM-VAT, uses a response surface modeling(RSM) methodology and serves as a visualization and analysis tool(VAT) for three-dimensional air quality data obtained by atmospheric models. The software features a number of powerful and intuitive data visualization functions for illustrating the complex nonlinear relationship between emission reductions and air quality benefits. The case study of contiguous U.S.demonstrates that the enhanced RSM-VAT is capable of reproducing the air quality model results with Normalized Mean Bias < 2% and assisting in air quality policy making in near real time.Yun Zhu Yanwen Lao Carey Jang Chen-Jen Lin Jia Xing Shuxiao Wang Joshua S.Fu Shuang Deng Junping Xie Shicheng Long 2015Journal of Environmental Sciences2015,27,1:10
3Surface free energy of copper-zinc alloy for energy-saving of boiler显示文摘Cu-Zn, Cu-Zn-Sn, Cu-Zn-Ni alloys were melted by vacuum smelter. The effect factors to the surface free energy of the alloys such as chemical composition, crystal structure and surface crystal lattice distortion etc. were investigated by OCA30 automatic contact angle test instrument, metallography microscope and XRD instrument etc. Results suggests: adding alloy element to Cu may increase its surface free energy, and the more kinds of alloy elements are added, the more surface free energy increases; the alloy element Sn an increase the surface free energy of Cu-Zn alloy; Cu-Zn alloy with fir-tree crystal structure, great phase discrepancy and obvious composition aliquation has greater surface free energy; Cu-Zn alloy with compounds and serious surface crystal lattice distortion has greater surface free energy.WANG Man LIANG Jinsheng TANG Qingguo MING Xing MENG Junping DING Yan 2006Rare Metals2006,25,z1:6
4Evaluation of sperm mitochondrial function using rh123/PI dual fluorescent staining in asthenospermia and oligoasthenozoospermia显示文摘Objective:The recent advent of flow cytometry(FCM),coupled with fluorescent dyes,has been successfully applied to assess mitochondrial function.The aim of this study was to investigate the feasibility and clinical significance of detecting sperm mitochondrial function and to evaluate sperm mitochondrial function by using Rhodamine 123/propidium(Rh123/PI)dual fluorescent staining and FCM in asthenospermia and oligoasthenozoospermia.Methods:Twenty-five fertile men(with normal sperm parameters)and 230 infertile patients were examined.Fifty-five patients of the above 230 patients were selected for idiopathic infertility samples and were divided into two groups:asthenospermia(n=30)and oligoasthenozoospermia(n=25).Rh123/PI dual fluorescent staining and FCM were carried out to examine sperm mitochondrial function.Results:Significant differences were found between the normal and abnormal semen samples(P<0.05)when Rh123+/PI-,Rh123-/PI+and Rh123-/PI-sperm were examined by FCM,but there was no significant difference between the asthenospermia(P=0.469) and oligoasthenozoospermia group(P=0.950)when Rh123+/PI-and Rh123-/PI+sperm were then examined;however,a significant difference was found between the 2 groups(P=0.003)when Rh123-/PI-sperm were examined.There was no correlation between Rh123-/PI-sperm and semen parameters in the normal group,but there was a significant negative correlation between the sperm concentration and Rh123-/PI-sperm in asthenospermia and oligoasthenozoospermia patients(r=-0.509,-0.660;P=0.018,0.038).Conclusion:Rh123/PI dual fluorescent staining and FCM can provide reliable information to assess the quality of sperm and reveal differences in mitochondrial membrane potential in asthenospermia and oligoasthenozoospermia.Tiejun Zou Xiang Liu Shangshu Ding Junping Xing 2010The Journal of Biomedical Research2010,24,5:4
5Geochemistry, Paleoenvironment and Mechanism of Organic-Matter Enrichment in the Lower Silurian Longmaxi Formation Shale in the Sichuan Basin, China显示文摘To investigate the mechanism of the organic-matter enrichment in the Lower Longmaxi Formation shale,the geochemistry and total organic carbon(TOC)of the Longmaxi Formation black shales in the Jiaoshiba,Zhaotong,and Weiyuan areas of the Sichuan Basin were analyzed.Paleoproductivity proxy parameters(Babio,Siex,and Ni/Al),clastic influx proxies(TiO2 and Ti/Al),redox indices(V/Cr,Ni/Co,V/(V+Ni),and U/Th),and hydrothermal indicators(Fe,Mn,and Y concentrations;Fe/Ti ratio and a Ni-Zn-Co diagram)were employed to decipher the paleoenvironment of the Lower Longmaxi Formation shales.TiO2 and Ti/Al indicated low terrigenous detrital influx in all three areas.However,Babio,Siex,and Ni/Al indicated high productivity in the Jiaoshiba area.V/Cr,Ni/Co,and U/Th indicated higher oxygen content with larger fluctuations in the Zhaotong and Weiyuan areas.Fe,Mn,and Y concentrations and the Fe/Ti ratio implied greater active hydrothermal activity in the Weiyuan area.These heterogeneities were considered to be closely related to the paleoenvironment and paleogeography,and the large basement faults that developed during the Chuanzhong paleo-uplift could have provided vents for deep-hydrothermal-fluid upwelling.The redox indices(V/Cr,Ni/Co,and U/Th)and a paleoproductivity proxy(Ni/Al)displayed a significant correlation with the TOC,suggesting that both excellent preservation conditions and high paleoproductivity were the controlling factors for the enrichment of organic matter in the Longmaxi Formation shale.There was no obvious correlation between the clastic influx proxy(Ti/Al)and the TOC due to the extremely low supply of terrigenous debris.The hydrothermal indicator(Fe/Ti)was negatively correlated with the TOC in the Weiyuan area,indicating that hydrothermal activity may have played a negative role in the accumulation of organic matter.This study suggests that the enrichment of organic matter in the Longmaxi Formation marine shale varied according to the paleogeography and sedimentary environment.CHEN Zhipeng CUI Junping REN Zhanli JIANG Shu LIANG Xing WANG Gaocheng ZOU Chen 2019Acta Geologica Sinica(English Edition)2019,93,3:3
6Anti-proliferative effect of the extract of Guangzao (Fructus Choerospondiatis) on cultured rat cardiac fibroblasts显示文摘OBJECTIVE: To ascertain if total flavonoids of Guangzao(Fructus Choerospondiatis)(TFFC) extracted from Guangzao(Fructus Choerospondiatis) can inhibit angiotensin Ⅱ-induced proliferation of cardiac fibroblasts(CFs).METHODS: CFs were cultured by the differential attachment method. A model of cell proliferation was established by stimulation with Ang Ⅱ. Cardiac fibroblasts growth was determined using a hemocytometer. Cell proliferation was detected by methyl thiazole tetrazolium. Lactate dehydrogenase activitywas measured by chemical colorimetric method.RESULTS: Proliferation of TFFC-treated(25, 50,100 mg/L) fibroblasts was significantly less than that of cells in the angiotensin Ⅱ group(P < 0.01),and TFFC inhibited proliferation in a dose-dependent manner. These inhibitory effects were partly blocked by pretreatment with NG-nitro-L-arginine methyl ester(L-NAME) and 1H-[1,2,4]-oxadiazole-[4,3-a]-quinoxalin-1-one(ODQ).CONCLUSION: TFFC inhibited angiotensinⅡ-induced proliferation of cardiac fibroblasts via a mechanism that probably involves activation of the NO-cyclic guanosine monophosphate signaling pathway.Jia Lei Yang Yumin Zhu Deli Gao Xiaohui Wang Xiaoling Xing Huihui Bao Junping Shu Liang 2015Journal of Traditional Chinese Medicine2015,35,6:2
7Association between 5-HTTLPR and STin2 VNTR polymorphisms in the serotonin transporter gene and clinical response of a selective serotonin reuptake inhibitor (dapoxetine) in lifelong premature ejaculation显示文摘To the Editor:Premature ejaculation(PE)is one of the commonplace male sexual dysfunctions affecting about 30%of men worldwide.PE can either be lifelong or acquired.Genetic polymorphisms situated on the SLC6A4 of humans encoding the 5-hydroxytryptamine transporter(serotonin transporter)(5-HTT)also called the serotonin transporter(SERT),a significant controller of serotonergic neurotransmission,were related to the pathogenesis of PE.[1,2]Polymorphisms in SLC6A4 are associated with the incidence of lifelong premature ejaculation(LPR).The effects of 5-hydroxytryptamine(serotonin)transporter gene-linked polymorphic region(5-HTTLPR)and serotonin transporter gene intron 2(STin2)polymorphism on lifelong PE(LPE)are controversial.We aimed to determine possible relationships between 5-HTTLPR and STin2 polymorphisms in the SERT gene and clinical response of a selective serotonin reuptake inhibitor(dapoxetine)in LPE.Abdullah Yang Yang Shang-Shu Ding Ping Sun Huoyong-Wei Tian Hong Junping Xing 2022Chinese Medical Journal2022,,13:0
8A new sensitivity model with blank space for layout optimization显示文摘As the technology scales advancing into the nanometer region,the concept of yield has become an increasingly important design metric.To reduce the yield loss caused by local defects,layout optimization can play a critical role.In this paper,we propose a new open sensitivity-based model with consideration of the blank space around the net,and study the corresponding net optimization.The proposed new model not only has a high practicability in the selection of nets to be optimized but also solves the issue of the increase in short critical area brought during the open optimization,which means to reduce the open critical area with no new short critical area produced,and thereby this model can ensure the decrease of total critical area and finally achieves an integrative optimization.Compared with the models available,the experimental results show that our sensitivity model not only consumes less time with concise algorithm but also can deal with irregular layout,which is out of the scope of other models.At the end of this paper,the effectiveness of the new model is verified by the experiment on the randomly selected five metal layers from the synthesized OpenSparc circuit layout.Junping Wang Yao Wu Shigang Liu Runsen Xing 2017Journal of Semiconductors2017,38,6:0
