| 1 | The Convergence of Least-Squares Progressive Iterative Approximation for Singular Least-Squares Fitting System显示文摘Data fitting is an extensively employed modeling tool in geometric design. With the advent of the big data era, the data sets to be fitted are made larger and larger, leading to more and more least-squares fitting systems with singular coefficient matrices. LSPIA (least-squares progressive iterative approximation) is an efficient iterative method for the least-squares fitting. However, the convergence of LSPIA for the singular least-squares fitting systems remains as an open problem. In this paper, the authors showed that LSPIA for the singular least-squares fitting systems is convergent. Moreover, in a special case, LSPIA converges to the Moore-Penrose (M-P) pseudo-inverse solution to the least- squares fitting result of the data set. This property makes LSPIA, an iterative method with clear geometric meanings, robust in geometric modeling applications. In addition, the authors discussed some implementation detail of LSPIA, and presented an example to validate the convergence of LSPIA for the singular least-squares fitting systems. | LIN Hongwei CAO Qi ZHANG Xiaoting | 2018 | Journal of Systems Science & Complexity2018，31，6： | 11 |
| 2 | Preliminary Validation of High Performance Liquid Chromatography Method for Detection of Methyl-testosterone Residue in Carp Muscle显示文摘The use of synthetic anabolic steroid methyltestosterone (MT) as growth promoter is prohibited in China. Vali-dations of analytical methods for MT residue in food and the results obtained have become indispensable. The high perfor-mance liquid chromatography (HPLC) method for the detection of MT with liquid-liquid extraction by trichloromethane-methanol in carp muscle tissue was preliminarily validated with reference to the following parameters: recovery (accuracy)at the 1, 5 and 10mg kg-1 level, between-run and within-run CV values (repeatability, also called relative standard deviation(RSD)) and limit of detection. The recoveries were above 80% and the between-run and within-run CV values below 10%for muscle tissue. The limit of detection was 0.05 mg kg-1. | JIANG Jie LIN Hong FU Xiaoting LI Mingming | 2005 | Journal of Ocean University of China2005，4，3： | 10 |
| 3 | Optimization of Culturing Condition and Medium Composition for the Production of Alginate Lyase by a Marine Vibrio sp. YKW-34显示文摘Carbohydrases secreted by marine Vibrio sp. YKW-34 with strong Laminaria cell wall degrading ability were screened, and among them alginate lyase was found to be dominant. The effects of medium composition and culturing condition on the produc- tion of alginate lyase by marine Vibrio sp. YKW-34 in flask were investigated in this study. In the culture medium of marine broth, no alginate lyase was produced. The activity of the alginate lyase, after being induced, reached 5 UmL–1. The best inoculum volume and inoculum age were 10% and 12 h, respectively. The optimal temperature for alginate lyase production was 25℃. The fermentation medium was composed of 0.5% of Laminaria powder and 0.2% of KNO3 with an initial acidity of pH 8.0. Alginate could induce alginate lyase production but not as efficiently as Laminaria powder did. The addition of fucoidan, cellulose and glucose had nega- tive effect on the alginate lyase production. Other kinds of nitrogen sources, such as yeast extract, beef extract and peptone, had posi- tive effect on the growth of the microorganism and negative effect on alginate lyase production. In addition, the time course of algi- nate lyase production under the optimized condition was described. The optimal harvest time was 48 h. | FU Xiaoting LIN Hong KIM Sang Moo | 2008 | Journal of Ocean University of China2008，7，1： | 6 |
| 4 | The application of carbon materials in nonaqueous Na‐O2 batteries显示文摘Na‐O2 batteries are advantageous as the candidates of next‐generation electric vehicles due to their ultrahigh theoretical energy density and have attracted enormous attention recently.Tremendous efforts have been devoted to improve the Na‐O2 battery performance by designing advanced electrodes with various carbonbased materials.Carbon materials used in Na‐O2 batteries not only function as the air electrode to provide active sites and accommodate discharge products but also as Na anode protectors against dendrite growth and chemical/electrochemical corrosion.In this review,we mainly focus on the application of various carbonbased materials in Na‐O2 batteries and highlight their advances.The scientific understanding on the fundamental design of the material microstructure and chemistry in relation to the battery performance are summarized.Finally,perspectives on enhancing the overall battery performance based on the optimization and rational design of carbon‐based cell components are also briefly anticipated. | Xiaoting Lin Qian Sun Kieran Doyle Davis Ruying Li Xueliang Sun | 2019 | Carbon Energy2019，1，2： | 5 |
| 5 | Serum semaphorin 4C as a diagnostic biomarker in breast cancer:A multicenter retrospective study显示文摘Background:To date,there is no approved blood-based biomarker for breast cancer detection.Herein,we aimed to assess semaphorin 4C(SEMA4C),a pivotal protein involved in breast cancer progression,as a serum diagnostic biomarker.Methods:We included 6,213 consecutive inpatients from Tongji Hospital,Qilu Hospital,and Hubei Cancer Hospital.Training cohort and two validation cohorts were introduced for diagnostic exploration and validation.A pan-cancer cohort was used to independently explore the diagnostic potential of SEMA4C among solid tumors.Breast cancer patients who underwent mass excision prior to modified radical mastectomy were also analyzed.We hypothesized that increased pretreatment serum SEMA4C levels,measured using optimized in-house enzymelinked immunosorbent assay kits,could detect breast cancer.The endpoints were diagnostic performance,including area under the receiver operating characteristic curve(AUC),sensitivity,and specificity.Post-surgery pathological diagnosis was the reference standard and breast cancer staging followed the TNM classification.There was no restriction on disease stage for eligibilities.Results:We included 2667 inpatients with breast lesions,2378 patients with other solid tumors,and 1168 healthy participants.Specifically,118 patients with breast cancer were diagnosed with stage 0(5.71%),620 with stage I(30.00%),966 with stage II(46.73%),217 with stage III(10.50%),and 8 with stage IV(0.39%).Patients with breast cancer had significantly higher serum SEMA4C levels than benign breast tumor patients and normal controls(P<0.001).Elevated serum SEMA4C levels had AUC of 0.920(95%confidence interval[CI]:0.900–0.941)and 0.932(95%CI:0.911–0.953)for breast cancer detection in the two validation cohorts.The AUCs for detecting early-stage breast cancer(n=366)and ductal carcinoma in situ(n=85)were 0.931(95%CI:0.916–0.946)and 0.879(95%CI:0.832–0.925),respectively.Serum SEMA4C levels significantly decreased after surgery,and the reduction was more striking after modified radical mastectomy,compared with mass excision(P<0.001).The positive rate of enhanced serum SEMA4C levels was 84.77%for breast cancer and below 20.75%for the other 14 solid tumors.Conclusions:Serum SEMA4C demonstrated promising potential as a candidate biomarker for breast cancer diagnosis.However,validation in prospective settings and by other study groups is warranted. | Ya Wang Long Qiao Jie Yang Xiong Li Yaqi Duan Jiahao Liu Shaoqi Chen Huayi Li Dan Liu Tian Fang Jingjing Ma Xiaoting Li Fei Ye Junxiang Wan Juncheng Wei Qin Xu Ensong Guo Ping Jin Mingfu Wu Lin Zhang Yun Xia Yaqun Wu Jun Shao Yaojun Feng Qing Zhang Zongyuan Yang Gang Chen Qinghua Zhang Xingrui Li Shixuan Wang Junbo Hu Xiaoyun Wang Mona P.Tan Kazuaki Takabe Beihua Kong Qifeng Yang Ding Ma Qinglei Gao | 2021 | Cancer Communications2021，41，12： | 3 |

| 13 | Integrative Analysis of Genome,3D Genome,and Transcriptome Alterations of Clinical Lung Cancer Samples显示文摘Genomic studies of cancer cell alterations,such as mutations,copy number variations(CNVs),and translocations,greatly promote our understanding of the genesis and development of cancers.However,the 3D genome architecture of cancers remains less studied due to the complexity of cancer genomes and technical difficulties.To explore the 3D genome structure in clinical lung cancer,we performed Hi-C experiments using paired normal and tumor cells harvested from patients with lung cancer,combining with RNA sequenceing analysis.We demonstrated the feasibility of studying 3D genome of clinical lung cancer samples with a small number of cells(1×10^(4)),compared the genome architecture between clinical samples and cell lines of lung cancer,and identified conserved and changed spatial chromatin structures between normal and cancer samples.We also showed that Hi-C data can be used to infer CNVs and point mutations in cancer.By integrating those different types of cancer alterations,we showed significant associations between CNVs,3D genome,and gene expression.We propose that 3D genome mediates the effects of cancer genomic alterations on gene expression through altering regulatory chromatin structures.Our study highlights the importance of analyzing 3D genomes of clinical cancer samples in addition to cancer cell lines and provides an integrative genomic analysis pipeline for future larger-scale studies in lung cancer and other cancers. | Tingting Li Ruifeng Li Xuan Dong Lin Shi Miao Lin Ting Peng Pengze Wu Yuting Liu Xiaoting Li Xuheng He Xu Han Bin Kang Yinan Wang Zhiheng Liu Qing Chen Yue Shen Mingxiang Feng Xiangdong Wang Duojiao Wu Jian Wang Cheng Li | 2021 | Genomics, Proteomics & Bioinformatics2021，19，5： | 1 |
| 14 | Deep learning model improves radiologists'performance in detection and classification of breast lesions显示文摘Objective:Computer-aided diagnosis using deep learning algorithms has been initially applied in the field of mammography,but there is no large-scale clinical application.Methods:This study proposed to develop and verify an artificial intelligence model based on mammography.Firstly,mammograms retrospectively collected from six centers were randomized to a training dataset and a validation dataset for establishing the model.Secondly,the model was tested by comparing 12 radiologists’performance with and without it.Finally,prospectively enrolled women with mammograms from six centers were diagnosed by radiologists with the model.The detection and diagnostic capabilities were evaluated using the freeresponse receiver operating characteristic(FROC)curve and ROC curve.Results:The sensitivity of model for detecting lesions after matching was 0.908 for false positive rate of 0.25 in unilateral images.The area under ROC curve(AUC)to distinguish the benign lesions from malignant lesions was0.855[95%confidence interval(95%CI):0.830,0.880].The performance of 12 radiologists with the model was higher than that of radiologists alone(AUC:0.852 vs.0.805,P=0.005).The mean reading time of with the model was shorter than that of reading alone(80.18 s vs.62.28 s,P=0.032).In prospective application,the sensitivity of detection reached 0.887 at false positive rate of 0.25;the AUC of radiologists with the model was 0.983(95%CI:0.978,0.988),with sensitivity,specificity,positive predictive value(PPV),and negative predictive value(NPV)of94.36%,98.07%,87.76%,and 99.09%,respectively.Conclusions:The artificial intelligence model exhibits high accuracy for detecting and diagnosing breast lesions,improves diagnostic accuracy and saves time. | Yingshi Sun Yuhong Qu Dong Wang Yi Li Lin Ye Jingbo Du Bing Xu Baoqing Li Xiaoting Li Kexin Zhang Yanjie Shi Ruijia Sun Yichuan Wang Rong Long Dengbo Chen Haijiao Li Liwei Wang Min Cao | 2021 | Chinese Journal of Cancer Research2021，33，6： | 1 |
| 15 | Allogeneic gene-edited HIV-specific CAR-T cells secreting PD-1 blocking scFv enhance specific cytotoxic activity against HIV Envt cells in vivo显示文摘HIV-specific chimeric antigen receptor(CAR)T-cells have been developed to target HIV-1 infected CD4t T-cells that express HIV Env proteins.However,T cell exhaustion and the patient-specific autologous paradigm of CAR-T cell hurdled clinical applications.Here,we created HIV-specific CAR-T cells using human peripheral blood mononuclear cells and a 3BNC117-E27(3BE)CAR construct that enabled the expression of programmed cell death protein(PD-1)-blocking scFv E27 and the single-chain variable fragment of the HIV-1-specific broadly neutralizing antibody 3BNC117 to target native HIV Env.Compared with T cells expressing 3BNC117-CAR alone,3BE CAR-T cells showed greater cytotoxic activity against HIV Envt cells with stronger proliferation capability,higher killing efficiency,and enhanced cytokine secretion in the presence of HIV Env-expressing cells.Furthermore,we manufactured TCR-deficient 3BE CAR-T cells through gene editing and demonstrated that these CAR-T cells could effectively kill HIV Env^(+) cells in vivo without the occurrence of severe graft-versus-host disease(GvHD)in NSG mice.These data suggest that we have provided a feasible approach to the generation of“off-theshelf”anti-HIV CAR-T cells in combination with PD-1 checkpoint blockade immunotherapy,which can be a powerful therapeutic candidate for the functional cure of HIV. | Hanyu Pan Xinyi Yang Jing Wang Huitong Liang Zhengtao Jiang Lin Zhao Yanan Wang Zhiming Liang Xiaoting Shen Qinru Lin Yue Liang Jinglong Yang Panpan Lu Yuqi Zhu Min Li Pengfei Wang Jianqing Xu Hongzhou Lu Huanzhang Zhu | 2023 | Virologica Sinica2023，38，2： | 0 |
| 16 | Comparison of genetic impact on growth and wood traits between seedlings and clones from the same plus trees of Pinus koraiensis显示文摘To evaluate the relationships among clones and open pollinated families from the same plus trees and to select elite breeding materials,growth,and wood characteristics of 33-year-old Pinus korainsis clones and families were measured and analyzed.The results show that growth and wood characters varied significantly.The variation due to clonal effects was higher than that of family effects.The ratio of genetic to phenotypic coefficient of variation of clones in growth and wood traits was above 90%,and the repeatability of these characteristics was more than 0.8,whereas the ratio of genetic to phenotypic coefficient of variation of families was above 90%.The broad-sense heritability of all characteristics exceeded 0.4,and the narrow-sense family heritability of growth traits was less than 0.3.Growth characteristics were positively correlated with each other,but most wood properties were weakly correlated in both clones and families.Fiber length and width were positively correlated between clones and families.Using the membership function method,eleven clones and four families were selected as superior material for improved diameter growth and wood production,and two families from clonal and open-pollinated trees showed consistently better performance.Generally,selection of the best clones is an effective alternative to deployment of families as the repeatability estimates from clonal trees were higher than narrow-sense heritability estimates from open pollinated families.The results provide valuable insight for improving P.koraiensis breeding programs and subsequent genetic improvement. | Xiaoting Liu Zhimin Lu Jingui Wu Yuchun Yang Shuchun Li Lin Wu Qingshan Xu Qi Yu Li Zhao Jian Sun Wei Zheng Mulualem Tigabu Xiyang Zhao | 2023 | Journal of Forestry Research2023，34，2： | 0 |
| 17 | Glide symmetry protected higher-order topological insulators from semimetals with butterfly-like nodal lines显示文摘Most topological insulators(TIs)discovered today in spinful systems can be transformed from topological semimetals(TSMs)with vanishing bulk gap via introducing the spin-orbit coupling(SOC),which manifests the intrinsic links between the gapped topological insulator phases and the gapless TSMs.Recently,we have discovered a family of TSMs in time-reversal invariant spinless systems,which host butterfly-like nodal-lines(NLs)consisting of a pair of identical concentric intersecting coplanar ellipses(CICE).In this Communication,we unveil the intrinsic link between this exotic class of nodal-line semimetals(NLSMs)and a Z_(4)=2 topological crystalline insulator(TCI),by including substantial SOC.We demonstrate that in three space groups(i.e.,Pbam(No.55),P4/mbm(No.127),and P4_(2)/mbc(No.135)),the TCI supports a fourfold Dirac fermion on the(001)surface protected by two glide symmetries,which originates from the intertwined drumhead surface states of the CICE NLs.The higher order topology is further demonstrated by the emergence of one-dimensional helical hinge states,indicating the discovery of a higher order topological insulator protected by a glide symmetry. | Xiaoting Zhou Chuang-Han Hsu Cheng-Yi Huang Mikel Iraola Juan L.Mañes Maia G.Vergniory Hsin Lin Nicholas Kioussis | 2021 | npj Computational Materials2021，，1： | 0 |
| 18 | Toward batch synthesis of high-quality graphene by cold-wall chemical vapor deposition approach显示文摘Chemical vapor deposition(CVD)has emerged as a promising approach for the controlled growth of graphene films with appealing scalability,controllability,and uniformity.However,the synthesis of high-quality graphene films still suffers from low production capacity and high energy consumption in the conventional hot-wall CVD system.In contrast,owing to the different heating mode,cold-wall CVD(CW-CVD)system exhibits promising potential for the industrial-scale production,but the quality of as-received graphene remains inferior with limited domain size and high defect density.Herein,we demonstrated an efficient method for the batch synthesis of high-quality graphene films with millimeter-sized domains based on CW-CVD system.With reduced defect density and improved properties,the as-received graphene was proven to be promising candidate material for electronics and anti-corrosion application.This study provides a new insight into the quality improvement of graphene derived from CW-CVD system,and paves a new avenue for the industrial production of high-quality graphene films for potential commercial applications. | Kaicheng Jia Ziteng Ma Wendong Wang Yongliang Wen Huanxin Li Yeshu Zhu Jiawei Yang Yuqing Song Jiaxin Shao Xiaoting Liu Qi Lu Yixuan Zhao Jianbo Yin Luzhao Sun Hailin Peng Jincan Zhang Li Lin Zhongfan Liu | 2022 | Nano Research2022，15，11： | 0 |
| 19 | Prevalence and risk factors for minimal hepatic encephalopathy in cirrhotic patients with different etiologies显示文摘Aims:Minimal hepatic encephalopathy(MHE)significantly affects the prognosis of patients with cirrhosis.This study was performed to determine whether there is a difference in the prevalence of MHE among patients with cirrhosis of different etiologies and whether the etiology directly influences the occurrence of MHE.Methods:This multicenter,cross-sectional study enrolled 1879 patients with confirmed cirrhosis at 40 hospitals from October 25,2021,to January 10,2023(Trial registration:http://gffzzd3f38a9638994581spqfwow0uocv06ofq.ffgz.tsg.suse.edu.cn/[NCT05140837]).The patients'demographics,etiologies of cirrhosis,and laboratory test results were collected.The psychometric hepatic encephalopathy score(PHES)was determined in all patients to screen for MHE.Multivariate logistic analyses were performed to identify the risk factors for MHE.Results:In total,736 patients with cirrhosis were analyzed.The prevalence of MHE was 42.0%(n=309).The primary etiology among all patients was hepatitis B virus(HBV)-related cirrhosis(71.9%[529/736]).The prevalence of MHE was significantly higher in patients with alcoholic cirrhosis(57.1%[40/70])than in those with HBV-related cirrhosis(40.6%[215/529],p=0.009)or hepatitis C virus(HCV)-related cirrhosis(38.2%[26/68],p=0.026).Age(odds ratio[OR],1.042;95%confidence interval[CI],1.024-1.059;p<0.001),duration of education(OR,0.935;95%CI,0.899-0.971;p=0.001),etiology(OR,1.740;95%CI,1.028-2.945;p=0.039),and high MELD-Na scores(OR,1.038;95%CI,1.009-1.067;p=0.009)were independent risk factors for MHE.When patients with cirrhosis of different etiologies were analyzed separately,the results showed that age(OR,1.035;95%CI,1.014-1.057;p=0.001)and duration of education(OR,0.924;95%CI,0.883-0.966;p=0.001)were risk factors for MHE among patients with HBV-related cirrhosis,whereas age(OR,1.138;95%CI,1.033-1.254;p=0.009)and creatinine concentration(OR,16.487;95%CI,1.113-244.160;p=0.042)were risk factors for MHE in patients with HCV-related cirrhosis.No risk factors for MHE were found in patients with autoimmune cirrhosis.For patients with alcoholic cirrhosis,the platelet count(OR,1.014;95%CI,1.000-1.027;p=0.045)was a risk factor for MHE.The PHES subtest results were inconsistent among patients who had MHE with cirrhosis of different etiologies.Patients with HBV-related cirrhosis performed better on Number Connection Test B and the serial dotting test than those with alcoholic cirrhosis(p=0.007 and p<0.001),better on Number Connection Test B than those with HCV-related cirrhosis(p=0.020),and better on the line tracing test than those with autoimmune cirrhosis(p=0.037).Conclusion:The etiology of cirrhosis affected the prevalence of MHE and risk factors for MHE.The domains of major cognitive impairment varied among patients with cirrhosis of different etiologies.Further studies are required to verify these findings. | Xiaoyan Li Shanghao Liu Huiling Xiang Qingge Zhang Ying Guo Hongmei Zu Jing Wang Jiaojian Lv Xiaoning Zhang Fanping Meng Jiahuan Li Jie Li Yangzhen Bianba Jia Shang Guo Zhang Fei Liu Zhaowei Tong Chuang Lei Wei Ye Qiaohua Yang Ningning Wang Ying Song Wei Fu Ziyue Li Yanjing Gao Yongping Zhang Jiafang Chen Caiyun Wu Qi Zheng Fang Wang Jiali Yu Lianjie Lin Chuanlong Yang Xiaoting Yang Xiaomin Ye Xiangmei Wang Xuelan Zhao Xiaolong Qi Fusheng Wang Junliang Fu | 2023 | Portal Hypertension & Cirrhosis2023，2，4： | 0 |
| 20 | Preliminary investigation of building damage in Hatay under February 6,2023 Turkey earthquakes显示文摘On February 6,2023,an M_(w)7.8 earthquake hit the south of Kahramanmaras prefecture,Turkey,followed by another M_(w)7.5 earthquake after nine hours in the middle region of the Kahramanmaras prefecture.More than 84,000 buildings collapsed or were severely damaged,and more than 50,000 lives were lost in Turkey and Syria.Some of the authors,as members of Chinese rescue team,entered Antakya,Hatay prefecture,and investigated the damaged buildings.This paper first summarizes the damage patterns of buildings and provides three reasons for the massive number of collapsed buildings;i.e.,the lack of seismic measures for better ductility,site effects such as liquefaction and surface rupture,and pronounced low-frequency components of the ground motions.Next,the seismic responses of two typical buildings are calculated based on the geometric data estimated by visual inspection.The results imply that the resonance of the whole structure and the poorer ductility of key members resulted in the collapse of buildings.Finally,some conclusions are drawn.Note that although a large number of buildings were seriously damaged to collapse,the majority of buildings in the areas of extreme shaking were lightly or moderately damaged,which implies that well designed and constructed buildings were able to survive and protect human lives even in over-design earthquakes. | Wang Tao Chen Jie Zhou Yujiang Wang Xiaoqing Lin Xuchuan Wang Xiaoting Shang Qingxue | 2023 | Earthquake Engineering and Engineering Vibration2023，22，4： | 0 |
