1A new approach to water resources system assessment——set pair analysis method显示文摘Most traditional assessment methods, which have complicated mathematic formulas, are difficult for calculation and application in water resources system assessment. A new approach to water resources system assessment, the set pair analysis method (SPAM), has been proposed based on the principle of set pair analysis (SPA). The basic ideals and steps of SPAM are discussed. The proposed method can take fuzzy property of threshold values for grade standards into full account and avoid determining the discrepancy uncertainty coefficient i or i1, i2, i3, … in SPA. The presented method is simple in concept, convenient to calculate and feasible for application. Two case studies of water resources assessment have been made. The results show that the proposed method is satisfactory.WANG WenSheng JIN JuLiang DING Jing LI YueQing 2009Science China(Technological Sciences)2009,52,10:43
2Review on the study of entanglement in quantum computation speedup显示文摘The role the quantum entanglement plays in quantum computation speedup has been widely disputed. Some believe that quantum computation's speedup over classical computation is impossible if entan-glement is absent,while others claim that the presence of entanglement is not a necessary condition for some quantum algorithms. This paper discusses this problem systematically. Simulating quantum computation with classical resources is analyzed and entanglement in known algorithms is reviewed. It is concluded that the presence of entanglement is a necessary but not sufficient condition in the pure state or pseudo-pure state quantum computation speedup. The case with the mixed state remains open. Further work on quantum computation will benefit from the presented results.DING ShengChao1,3 & JIN Zhi1,2,1 Institute of Computing Technology,Chinese Academy of Sciences,Beijing 100080,China 2 Academy of Mathematics and Systems Science,Chinese Academy of Sciences,Beijing 100080,China 3 Graduate University of Chinese Academy of Sciences,Beijing 100080,China 2007Chinese Science Bulletin2007,52,16:34

5A mouse model of severe acute pancreatitis induced with caerulein and lipopolysaccharide显示文摘AIM: To establish a non-traumatic, easy to induce and reproducible mouse model of severe acute pancreatitis (SAP)induced with caerulein and lipopolyasccharide (LPS).METHODS: Thirty-two healthy mature NIH female mice were selected and divided at random into four groups (each of 8 mice), i.e., the control group (NS group), the caerulein group (Ch group), the lipopolysaccharide group (LPS group),and the caerulein+LPS group (Cn+LPS group). Mice were injected intraperitoneally with caerulein only, or LPS only,and caerulein and LPS in combination. All the animals were then killed by neck dislocation three hours after the last intraperitoneal injection. The pancreas and exo-pancreatic organs were then carefully removed for microscopic examination. And the pancreatic acinus was further observed under transmission electron microscope (TEM). Pancreatic weight, serum amylase, serum nitric oxide (NO)concentration, superoxide dismutase (SOD) and malondialdehyde (MDA) concentration of the pancreas were assayed respectively.RESULTS: (1) NS animals displayed normal pancreatic structure both in the exocrine and endocrine. In the LPS group, the pancreas was slightly edematous, with the infiltration of a few inflammatory cells and the necrosis of the adjacent fat tissues. All the animals of the Cn group showed distinct signs of a mild edematous pancreatitis characterized by interstitial edema, infiltration of neutrophil and mononuclear cells, but without obvious parenchyma necrosis and hemorrhage. In contrast, the Cn+LPS groupshowed more diffuse focal areas of nonviable pancreatic and hemorrhage as well as systemic organ dysfunction.According to Schmidt's criteria, the pancreatic histologic score showed that there existed significant difference in the Cn+LPS group in the interstitial edema, inflammatory infiltration,parenchyma necrosis and parenchyma homorrhage in comparison with those of the Cn group, LPS group and NS group (P<0.01 or P<0.05). (2) The ultrasturcture of acinar cells was seriously damaged in the Cn+LPS group. Chromatin margination of nuclei was present, the number and volume of vacuoles greatly increased. Zymogen granules (ZGs) were greatly decreased in number and endoplasmic reticulum exhibited whorls. The swollen mitochondria appeared, the crista of which was decreased in number or disappeared.(3) Pancreatic weight and serum amylase levels in the Cn +LPS was significantly higher than those of the NS group and the LPS group respectively (P<0.01 or P<0.05).However, the pancreatic wet weight and serum amylase concentration showed no significant difference between the Cn+LPS group and the Cn group. (4) NO concentration in the Cn+LPS group was significantly higher than that of NS group, LPS group and Cn group(P<0.05 or P<0.01). 5) The SOD and MDA concentration of the pancreas in the Cn+LPS group were significantly higher than those of NS, LPS and Cn groups (P<0.05 or P<0.01).CONCLUSION: The mouse model of severe acute pancreatitis could be induced with caerulein and LPS, which could be non-traumatic and easy to induce, reproducible with the same pathological characteristics as those of SAP in human, and could be used in the research on the mechanism of human SAP.Shi-Ping Ding Ji-Cheng Li Chang Jin Department of Lymphology,Department of Histology and Embryology,Medical College of Zhejiang University,Hangzhou 310031,Zhejiang Province,China 2003World Journal of Gastroenterology2003,9,3:33

9Principles and construction of MSD adder in ternary optical computer显示文摘The two remarkable features of ternary values and a massive unit with thousands bits of parallel computation will make the ternary optical computer (TOC) with modified signed-digit (MSD) adder more powerful and e?cient than ever before for numerical calculations. Based on the decrease-radix design presented previously, a TOC can satisfy either a user requiring huge capacity for data calculations or one with a moderate amount of data, if it is equipped with a prepared adder. Furthermore, with the application of pipelined operations and the proposed data editing technique, the e?ciency of the prepared adder can be greatly improved, so that each calculated result can be obtained almost within one clock cycle. It is hopeful that by employing a MSD adder, users will be able to enter a new dimension with the creation of a new multiplier, new divider, as well as new matrix operator in a TOC in the near future.JIN Yi SHEN YunFu PENG JunJie XU ShiYi DING GuangTai YUE DongJian YOU HaiHang 2010Science China(Information Sciences)2010,53,11:26

11Thermal energy storage:Challenges and the role of particle technology显示文摘Thermal energy is at the heart of the whole energy chain providing a main linkage between the primary and secondary energy sources.Thermal energy storage(TES)has a pivotal role to play in the energy chain and hence in future low carbon economy.However,a competitive TES technology requires a number of scientific and technological challenges to be addressed including TES materials,TES components and devices,and integration of TES devices with energy networks and associated dynamic optimization.This paper provides a perspective of TES technology with a focus on TES materials challenges using molten salts based phase change materials for medium and high temperature applications.Two key challenges for the molten salt based TES materials are chemical incompatibility and low thermal conductivity.The use of composite materials provides an avenue to meeting the challenges.Such composite materials consist of a phase change material,a structural supporting material,and a thermal conductivity enhancement material.The properties of the supporting material could determine the dispersion of the thermal conductivity enhancement material in the salt.A right combination of the salt,the structural supporting material,and the thermal conductivity enhancement material could give a hierarchical structure that is able to encapsulate the molten salt and give a substantial enhancement in the thermal conductivity.Understanding of the structure-property relationships for the composite is essential for the formulation design and fabrication of the composite materials.Linking materials properties to the system level performance is recommended as a key future direction of research.Zhiwei Ge Yongliang Li Dacheng Li Ze Sun Yi Jin Chuanping Liu Chuan Li Guanghui Leng Yulong Ding 2014Particuology2014,12,4:20

13A chlorinated copolymer donor demonstrates a 18.13% power conversion efficiency显示文摘The rapid development of low-bandgap(LBG)nonfullerene acceptors and wide-bandgap(WBG)copolymer donors in recent years has boosted the power conversion efficiency(PCE)of organic solar cells(OSCs)to the 18%level[1−21].The commercialization of OSCs is highly expected.However,critical issues like the cost and the stability also determine whether OSCs can enter the market or not[22].Jianqiang Qin Lixiu Zhang Chuantian Zuo Zuo Xiao Yongbo Yuan Shangfeng Yang Feng Hao Ming Cheng Kuan Sun Qinye Bao Zhengyang Bin Zhiwen Jin and Liming Ding 2021Journal of Semiconductors2021,42,1:19
14Soil pH impact on microbial tetraether lipids and terrestrial input index (BIT) in China显示文摘The distributions of microbial tetraether lipids i.e. glycerol dialkyl glycerol tetraethers (GDGTs) were investigated in a variety of Chinese soils featured by a wide range of pH values in different climate zones. The bacterial branched GDGTs and archaeal isoprenoid GDGTs were found to be widely distributed in Chinese soils and their relative abundance was controlled primarily by soil pH. The bacterial bGDGTs usually dominate over archaeal iGDGTs in abundance when the soil pH is below 8.0. However archaeal iGDGTs become dominant and the abundance of halophilic archaea characterized by GDGT V without cyclopentyl ring increases dramatically in the alkaline soil with pH greater than 8.0. The relative abundance of archaeal iGDGTs to bacterial bGDGTs was defined here as RAI index. The RAI index decreases with elevated soil pH and a linear correlation is found between them indicating that the relative abundance of archaeal iGDGTs to bacterial bGDGTs increases with increased pH. The RAI index thus could be a novel proxy of the pH values of paleosol. The terrestrial input index BIT (Branched and Isoprenoid Tetraethers Index) decreases with increased soil pH suggesting that soil pH should be taken into consideration when the terrestrial contribution to marine sediments is estimated by BIT index. Moreover the TEX86 index cannot be used to reconstruct sea surface temperature in the sediments featured by a large terrestrial input.YANG Huan DING WeiHua WANG JinXiang JIN ChengSheng HE GangQiang QIN YangMin XIE ShuCheng 2012Science China Earth Sciences2012,55,2:19

16Thiolactone copolymer donor gifts organic solar cells a 16.72% efficiency显示文摘Since 1995,bulk-heterojunction organic solar cells consisting of one or two organic donors and one or two organic acceptors have been fighting for high power conversion efficiencies(PCEs)and good stability[1].Until recent years,this next-generation photovoltaic technology starts to offer decent PCEs,shedding the light on commercialization,and attracting great attention again[2-14].Compared w让h the continuously emerging highperformance nonfullerene acceptors,high-performance donors are rare.Ji Xiong Ke Jin Yufan Jiang Jianqiang Qin Tan Wang Jinfeng Liu Qishi Liu Haili Peng Xiongfeng Li Anxin Sun Xianyi Meng Lixiu Zhang Ling Liu Wenting Li Zhimin Fang Xue Jia Zuo Xiao Yaqing Feng Xiaotao Zhang Kuan Sun Shangfeng Yang Shengwei Shi Liming Ding 2019Science Bulletin2019,64,21:17
17Ubiquitination of Rheb governs growth factor-induced mTORC1 activation显示文摘Mechanistic target of rapamycin mTOR complex 1 (mTORC1)plays a key role in the integration of various environmental signals to regulate cell growth and metabolism,mTORC1 is recruited to the lysosome where it is activated by its interaction with GTP-bound Rheb GTPase.However,the regulatory mechanism of Rheb activity remains largely unknown.Here,we show that ubiquitination governs the nucleotide-bound status of Rheb.Lysosome-anchored E3 ligase RNF152 catalyzes Rheb ubiquitination and promotes its binding to the TSC complex.EGF enhances the deubiquitination of Rheb through AKT-dependent USP4 phosphorylation,leading to the release of Rheb from the TSC complex.Functionally,ubiquitination of Rheb is linked to mTORC1-mediated signaling and consequently regulates tumor growth.Thus,we propose a mechanistic model whereby Rheb-mediated mTORC1 activation is dictated by a dynamic opposing act between Rheb ubiquitination and deubiquitination that are catalyzed by RNF152 and USP4 respectively.Lu Deng Lei Chen Linlin Zhao Yan Xu Xiaoping Peng Xinbo Wang Lin Ding Jiali Jin Hongqi Teng Yanming Wang Weijuan Pan Fei Yu Lujian Liao Li Li Xin Ge Ping Wang 2019Cell Research2019,29,2:16
18Determination of Seven Major Ginsenosides in Different Parts of Panax quinquefolius L.(American Ginseng) with Different Ages显示文摘Ginsenosides Rg1, Re, Rb1, Rc, Rb2, Rb3, and Rd in different parts of the American ginseng plant were investigated. The extraction process was a pressurized microwave-assisted extraction(PMAE). The seven ginsenosides were separated and determined by high-performance liquid chromatography(HPLC) with a ultraviolet(UV) detector, at 203 nm. The experiment results showed significant variations in the individual ginsenoside contents of the American ginseng in different parts and ages of the plant. The results demonstrated that the leaves, root hairs, and rhizomes of Panax quinquefolius L. contained higher ginsenoside contents, followed by the main roots and stems. The leaves contained dramatically higher levels of ginsenoside Rg1, Rb3, and Rd than the other four parts. Higher contents of Rb1 and Re were present in the main roots, root hairs, and rhizomes. The amount of ginsenoside content in the stems was the lowest. The total content of the seven ginsenosides in main roots, root hairs and rhizomes increased with the age of the plant. In contrast, the ginsenoside contents in the leaves and stems decreased with a year of growth.ZHANG Kun WANG Xiao DING Lan LI Juan QU Chen-ling CHEN Li-gang JIN Hai-yan ZHANG Han-qi 2008Chemical Research in Chinese Universities2008,24,6:15

20Antipyretic and anti-inflammatory activities of Thais luteostoma extracts and underlying mechanisms显示文摘Thais luteostoma has been utilized as a crude drug whose shell and soft tissue have been widely used for the treatment of heat syndrome in China for thousands of years. The present study was designed to investigate the antipyretic and anti-inflammatory activities of T. luteostoma. T. luteostoma was divided into shell(TLSH) and soft tissue(TLST) samples in the present study. The rat model of yeast-induced fever was used to investigate their antipyretic effects; and the rat model of hind paw edema induced by carrageenan was utilized to study their anti-inflammatory activities, and at the same time, the concentration variations of the central neurotransmitter [prostaglandin E2(PGE2) and cyclic adenosine monophosphate(cA MP)], inflammatory mediators [tumor necrosis factor(TNFα), interleukin-1β(IL-1), interleukin-2(IL-2) and interleukin-6(IL-6)] and ion(Na+ and Ca2+) were also tested. The results showed that TLSH and TLST extracts significantly inhibited yeast-induced pyrexia in rats(P < 0.05), and exhibited more lasting effects as compared to aspirin, and TLSH had the better antipyretic activity than TLST, and that TLSH and TLST could significantly prevent against carrageenan induced paw edema in rats(P < 0.05); and markedly reduced levels of PGE2, cA MP, TNFα, IL-1β, IL-2, IL-6, and Na+/Ca2+. In fever model, TLST could significantly reduce the levels of PGE2(P < 0.01) in rats' homogenate and TNFα(P < 0.05), IL-1β(P < 0.01) in the plasma than TLSH, whereas TLSH could reduce the content of IL-2(P < 0.01) and IL-6(P < 0.01) in plasma and increase the content of Ca2+(P < 0.01) in plasma and homogenate more significantly than TLST. In conclusion, T. luteostoma extract has antipyretic and anti-inflammatory activities, which may be mediated through the suppression of production of PGE2, c AMP, Na+/Ca2+, TNFα, IL-1β, IL-2, and IL-6.LIU Xin TANG Yu-Ping LIU Rui JIN Yi GUO Jian-Ming ZHAO Jin-Long DING Shao-Xiong LIN Xiang-Zhi LIN Ru-Rong DUAN Jin-Ao 2015Chinese Journal of Natural Medicines2015,13,3:15
