| 4 | Integration of genetic virtual screening patterns and latent multivariate modeling techniques for QSAR optimization based on combinations and/or interactions between peptides and proteins显示文摘Both the concept and the model of snug quantitative structure-activity relationship (QSAR) were pro-posed and developed for molecular design through constructing QSAR based on some known mode of receptor/ligand interactions. Many disadvantages of traditional models can be avoided by using the proposed method because the traditional models only determined upon molecular structural features in sample sets themselves. A genetic virtual screening of peptide/protein combinations (GVSPPC) is proposed for the first time by utilizing this idea to examine peptide/protein affinity activities. A genetic algorithm (GA) was developed for screening combinative targets with an interaction mode for virtual receptors. GVSPPC succeeds in disposing difficulties in rational QSAR,in order to search for the ligand/receptor interactions on conditions of unknown structures. Some bioactive oligo-/poly-peptide systems covering 58 angiotensin converting enzyme (ACE) inhibitors and 18 double site mutation residues in camel antibody protein cAb-Lys3 were investigated by GVSPPC with satisfactory results (R 2 cu>0.91,Q 2 cv > 0.86,ERMS=0.19-0.95),respectively,which demonstrates that GVSPPC is more inter-pretable in the ligand-receptor interaction than the traditional QSAR method. | LI ZhiLiang TIAN FeiFei WU ShiRong YANG ShanBin YANG ShengXi ZHOU Yuan ZHANG QiaoXia QIN RenHui MEI Hu CHEN Gang LI GenRong | 2008 | Science China Chemistry2008，51，5： | 0 |

| 6 | Jointly beam stealing attackers detection and localization without training:an image processing viewpoint显示文摘Recently revealed beam stealing attacks could greatly threaten the security and privacy of IEEE 802.11ad communications.The premise to restore normal network service is detecting and locating beam stealing attackers without their cooperation.Current consistency-based methods are only valid for one single attacker and are parametersensitive.From the viewpoint of image processing,this paper proposes an algorithm to jointly detect and locate multiple beam stealing attackers based on RSSI(Received Signal Strength Indicator)map without the training process involved in deep learning-based solutions.Firstly,an RSSI map is constructed based on interpolating the raw RSSI data for enabling high-resolution localization while reducing monitoring cost.Secondly,three image processing steps,including edge detection and segmentation,are conducted on the constructed RSSI map to detect and locate multiple attackers without any prior knowledge about the attackers.To evaluate our proposal’s performance,a series of experiments are conducted based on the collected data.Experimental results have shown that in typical parameter settings,our algorithm’s positioning error does not exceed 0.41 m with a detection rate no less than 91%. | Yaoqi YANG Xianglin WEI Renhui XU Weizheng WANG Laixian PENG Yangang WANG | 2023 | Frontiers of Computer Science2023，17，3： | 0 |
| 7 | Effects of Lujingyiqishengxue Pill on Iron Metabolism in Rats with Iron Deficiency Anemia显示文摘[Objectives]This study was conducted to observe the effect of Lujingyiqishengxue Pill on iron metabolism in rats with iron deficiency anemia. [Methods] The iron-deficiency anemia rat model was established by feeding low-iron diet. Meanwhile, the rats were given oral gavage of ferrous succinate(0.036 g/kg, positive drug group) and Lujingyiqishengxue Pill(4.4, 2.2, 1.1 g/kg, high, middle and low dose groups), once daily for 42 consecutive days. The body weight of the rats was observed every week, and the peripheral blood[red blood cells(RBC), hemoglobin(HGB), and hematocrit(HCT)]and the iron contents in tissues(the liver, spleen, small intestine, kidney) of the rats were detected after modeling;and serum iron(SI), serum total iron binding capacity(TIBC), transferrin saturation(TSAT), serum ferritin(SF) and serum transferrin receptor 1(TFR1) and other iron metabolism indexes were determined. [Results] Compared with the model group, the high-dose Lujingyiqishengxue Pill significantly reversed the peripheral blood(HGB, HCT) and iron contents of various tissues(the liver, spleen, small intestine, kidney) in rats(P<0.01), and significantly increased SI, TSAT, SF(P<0.01), while the contents of TIBC and TFR1 were significantly decreased(P<0.01). [Conclusions] Lujingyiqishengxue Pill can significantly improve anemia and regulate iron metabolism in rats with iron-deficiency anemia, which provides a pharmacological reference for the clinical application of Lujingyiqishengxue Pill. | Xianmei XU Lida CHEN Renhui YANG Hai ZHAO Yan WU | 2022 | Agricultural Biotechnology2022，11，5： | 0 |

| 11 | Tidal water exchanges can shape the phytoplankton community structure and reduce the risk of harmful cyanobacterial blooms in a semi-closed lake显示文摘For estuaries,inland lakes play a vital role in the ecological balance under the impact of tide s.The effect of tides-induced water exchange on phytoplankton community in a semi-closed lake was studied and compared with that of an adjacent closed lake in the Oujiang River mouth in Zhejiang,East China Sea,from June 29,2020 to June 14,2021.Results show that the dominant species,abundance,dominance,and diversity of the phytoplankton species between the two lakes were significantly different.In the closed lake,cyanobacteria were the dominant species during the study period.However.in the semi-closed lake,the diversification of the dominant species was greater,and some species of diatoms and green algae became dominant.The average phytoplankton abundance in the closed lake was 6 times of that in the semi-closed lake.The average dominance of cyanobacteria in the closed lake was 0.96,and those in the semi-closed lake and the Oujiang River were 0.51 and 0.22,respectively.Cyanobacterial blooms occurred throughout the study time in the closed lake but not in the semi-closed one.Furthermore,the species diversity richness of the phytoplankton in the semi-closed lake was higher than that of the closed one,and the phytoplankton community between the closed lake and semi-closed lake could be divided into distinctly different groups based on non-metic multidimensional scaling analysis(NMDS)and analysis of similarities(ANOSIM)analysis.The salinity of the water was significantly greater and the transparency significantly smaller in the semi-closed lake than those in the closed lake.Therefore,water exchange driven by local tidal movement increased salinity and decreased transparency of water,which consequently shaped the community structures of different phytoplankton and reduced the risk of a cyanobacterial bloom outbreak in the semi-closed lake. | Wenxu ZHENG Renhui LI Wenli QIN Binbin CHEN Min WANG Wanchun GUAN Xiaoling ZHANG Qiao YANG Min ZHAO Zengling MA | 2022 | Journal of Oceanology and Limnology2022，40，5： | 0 |
