1Symmetry theories of Hamiltonian systems with fractional derivatives显示文摘The Noether and Lie symmetries as well as the conserved quantities of Hamiltonian system with fractional derivatives are es-tablished. The definitions and criteria for the fractional symmetrical transformations and quasi-symmetrical transformations inthe Noether sense of Hamiltonian system are first discussed. Then, using the invariance of Hamiltonian action under the infini-tesimal transformations with respect to time, generalized coordinates and generalized momentums, the fractional Noethertheorem of the system is obtained. Further, the Lie symmetry and conserved quantity of the system are acquired. Two exam-ples are presented to illustrate the application of the results.ZHOU Sha FU Hao FU JingLi 2011Science China(Physics,Mechanics & Astronomy)2011,54,10:25
2Variations of pore water sulfate gradients in sediments as indicator for underlying gas hydrate in Shenhu Area, the South China Sea显示文摘Shenhu Area is one of the most promising areas for gas hydrate exploration in the northern South China Sea (SCS). Pore water sulfate gradient, sulfate-methane interface (SMI) depth, and sulfate flux were analyzed at 53 sites in this area. SO42 gradient ranges between 0.33 and 4.43 mmol L-1 m-1 . SMI depths are from 7.7 to 87.9mbsf. Sulfate flux varies between 2.0 and 26.9 mmol m-2 yr-1 , with a mean of 11.7 mmol m-2 yr-1 . Correlation coefficient between SMI depth and methane flux for the 53 sites is 0.80, implying that methane flux regulates the rate of anaerobic methane oxidation (AMO), SMI depth, and sulfate flux. Twelve anomalous fields with high methane flux and steep sulfate gradients were recognized. Bottom simulating reflector (BSR) is distributed mainly in areas where SMI depth is less than 50 mbsf or places with sulfate flux larger than 3.5 mmol m-2 yr-1 . It is suggested that the Baiyun Sag and the Southern Uplift are potential areas for gas hydrate exploration.WU LuShan YANG ShengXiong LIANG JinQiang SU Xin FU ShaoYing SHA ZhiBin YANG Tao 2013Science China Earth Sciences2013,56,4:24

5Effects of Salvia miltiorrhiza on intestinal microflora in rats with ischemia/reperfusion liver injury显示文摘BACKGROUND: Hepatic ischemia/reperfusion injury may induce intestinal microflora imbalance. Salvia miltiorrhiza is effective in promoting blood circulation and counteracting peroxidation in tissues. The aim of the present study was to determine the effects of Salvia miltiorrhiza on intestinal mi- croflora, endotoxemia, and bacterial translocation in rats with hepatic I/R injury. METHODS: Sprague-Dawley rats in specific pathogen free grade were divided into 3 groups: group I(n =6) for sham operation: groups ( n = 7) for liver ische- mia for 20 minutes and reperfusion for 22 hours. Group was also pretreated with 4 ml/day of Salvia miltiorrhiza solu- tion (250 mg/kg) by daily gavage for 7 days. The levels of serum alanine aminotransferase (ALT), aspartate amino- transferase (AST), malondialdehyde ( MDA) and supero- xide dismutase ( SOD ) in liver tissues, serum endotoxin, intestinal bacterial counts, intestinal mucosal histology and bacterial translocation were studied. RESULTS: The levels of ALT, AST, plasma endotoxin and MDA in liver tissues were decreased more markedly in group (57.57 ± 18.08 U/L, 147.57 ±40.84 U/L, 0.42 ± 0.144 EU/ml and 0. 52 ±0.19 nmol/mg-prot respectively) in group 295.9±216.92 U/L, 0.80± 0.262 EU/ml and 0.72±0.12 nmol/mg-prot; P <0.05-0.01 respectively). Liver SOD activity was increased more sig- nificantly in group (318.47±64.62 U/mg-prot) than in group U/mg-prot, P<0.05). The counts of Bifidobacteria and Bacteroides increased more significantly in group than in group but were similar to those in group I. Bacterial translocation to the kidney in group was 50% (5/10), whereas no bacterial translocation to the kidney occurred in the other two groups (P <0. 01). Ileal mucosal structure was markedly ameliorated in group as compared with group CONCLUSIONS: Salviae miltiorrhiza could partially restore intestinal microflora balance, improve intestinal mucosal integrity, and reduce bacterial translocation and plasma en- dotoxin in rats with hepatic ischemia/reperfusion injury.Hui-Chun Xing, Lan-Juan Li, Kai-Jin Xu, Tian Shen, Yun-Bo Chen, Yu Chen, Su-Zhen Fu, Ji-Fang Sheng, Chun-Lei Chen, Jian-Guo Wang, Dong Yan, Fang-Wei Dai and Xiao-Ying Sha Hangzhou, China Key Laboratory of Infectious Diseases, Ministry of Public Health of China, and Institute of Infectious Diseases, Department of Infectious Diseases, First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310003, China Zhejiang Academy of Medical Sciences, Hangzhou 310012, China 2005Hepatobiliary & Pancreatic Diseases International2005,4,2:14
6A new prognostic histopathologic classification of nasopharyngeal carcinoma显示文摘Background:The current World Health Organization(WHO) classification of nasopharyngeal carcinoma(NPC) con?veys little prognostic information.This study aimed to propose an NPC histopathologic classification that can poten?tially be used to predict prognosis and treatment response.Methods:We initially developed a histopathologic classification based on the morphologic traits and cell differentia?tion of tumors of 2716 NPC patients who were identified at Sun Yat?sen University Cancer Center(SYSUCC)(training cohort).Then,the proposed classification was applied to 1702 patients(retrospective validation cohort) from hospitals outside SYSUCC and 1613 patients(prospective validation cohort) from SYSUCC.The efficacy of radiochemotherapy and radiotherapy modalities was compared between the proposed subtypes.We used Cox proportional hazards models to estimate hazard ratios(HRs) with 95% confidence intervals(CI) for overall survival(OS).Results:The 5?year OS rates for all NPC patients who were diagnosed with epithelial carcinoma(EC;3708 patients),mixed sarcomatoid?epithelial carcinoma(MSEC;1247 patients),sarcomatoid carcinoma(SC;823 patients),and squamous cell carcinoma(SCC;253 patients) were 79.4%,70.5%,59.6%,and 42.6%,respectively(P < 0.001).In mul?tivariate models,patients with MSEC had a shorter OS than patients with EC(HR = 1.44,95% CI = 1.27–1.62),SC(HR = 2.00,95% CI = 1.76–2.28),or SCC(HR = 4.23,95% CI = 3.34–5.38).Radiochemotherapy significantly improved survival compared with radiotherapy alone for patients with EC(HR 49–0.75),and possibly for those with SCC(HR = 0.67,95% CI = 0.56–0.80),MSEC(HR = 0.58,95% CI = 0..74–1.28).= 0.63;95% CI = 0.40–0.98),but not for patients with SC(HR = 0.97,95% CI = 0Conclusions:The proposed classification offers more information for the prediction of NPC prognosis compared with the WHO classification and might be a valuable tool to guide treatment decisions for subtypes that are associ?ated with a poor prognosis.Hai-Yun Wang Yih-Leong Chang Ka-Fai To Jacqueline S.G.Hwang Hai-Qiang Mai Yan-Fen Feng Ellen T.Chang Chen-Ping Wang Michael Koon Ming Kam Shie-Lee Cheah Ming Lee Li Gao Hui-Zhong Zhang Jie-Hua He Hao Jiang Pei-Qing Ma Xiao-Dong Zhu Liang Zeng Chun-Yan Chen Gang Chen Ma-Yan Huang Sha Fu Qiong Shao An-Jia Han Hai-Gang Li Chun-Kui Shao Pei-Yu Huang Chao-Nan Qian Tai-Xiang Lu Jin-Tian Li Weimin Ye Ingemar Ernberg Ho Keung Ng Joseph T.S.Wee Yi-Xin Zeng Hans-Olov Adami Anthony T.C.Chan Jian-Yong Shao 2016Chinese Journal of Cancer2016,35,6:10
7Stem cell therapies and regenerative medicine in China显示文摘Stem cells are the core of tissue repair and regeneration,and a promising cell source for novel therapies.In recent years,research into stem cell therapies has been particularly exciting in China.The remarkable advancements in basic stem cell research and clinically effective trials have led to fresh insights into regenerative medicine,such as treatments for sweat gland injury after burns,diabetes,and liver injury.High hopes have inspired numerous experimental and clinical trials.At the same time,government investment and policy support of research continues to increase markedly.However,numerous challenges must be overcome before novel stem cell therapies can achieve meaningful clinical outcomes.HUANG Sha FU XiaoBing 2014Science China(Life Sciences)2014,57,2:10
8TNF-α suppresses sweat gland differentiation of MSCs by reducing FTO-mediated m^6 A-demethylation of Nanog mRNA显示文摘An effect of inhibition of tumor necrosis factor-α(TNF-α)on differentiation of mesenchymal stromal cells(MSCs)has been demonstrated,but the exact mechanisms that govern MSCs differentiation remain to be further elucidated.Here,we show that TNF-αinhibits the differentiation of MSCs to sweat glands in a specific sweat gland-inducing environment,accompanied with reduced expression of Nanog,a core pluripotency factor.We elucidated that fat mass and obesity-associated protein(FTO)-mediated m^6 A demethylation is involved in the regulation of MSCs differentiation potential.Exposure of MSCs to TNF-αreduced expression of FTO,which demethylated Nanog m RNA.Reduced expression of FTO increased Nanog m RNA methylation,decreased Nanog m RNA and protein expression,and significantly inhibited MSCs capacity for differentiation to sweat gland cells.Our finding is the first to elucidate the functional importance of m^6 A modification in MSCs,providing new insights that the microenvironment can regulate the multipotency of MSCs at the post-transcriptional level.Moreover,to maintain differentiation capacity of MSCs by regulating m^6 A modification suggested a novel potential therapeutic target for stem cellmediated regenerative medicine.Yihui Wang Rui Wang Bin Yao Tian Hu Zhao Li Yufan Liu Xiaoli Cui Liuhanghang Cheng Wei Song Sha Huang Xiaobing Fu 2020Science China(Life Sciences)2020,63,1:9

10Effects of different fertilizations on fruit quality,yield and soil fertility in field-grown kiwifruit orchard显示文摘Kiwifruit yield and quality and soil nutrients were investigated in a kiwifruit orchard after long-term fertilization to understand the relationship between kiwifruit growth and soil nutrition.Seven fertilization treatments with three replications were applied in a continuous four-year period,including no fertilizer(CK);phosphorus(P)and potassium(K)fertilizers(PK);N and K fertilizers(NK);N and P fertilizers(NP);N,P and K fertilizers(NPK);1.5 times of N,P and K fertilizers(1.5NPK);and chemical fertilizers plus swine manure(NPKM).Fertilization increased kiwifruit yield at the rate of 450 kg N/hm^(2),225 kg P2O5/hm^(2),300 kg K2O/hm^(2).The average yield decreased in a descending order for NPKM(44.6 t/hm^(2)),1.5NPK(42.6 t/hm^(2)),NPK(42.0 t/hm^(2)),NK(38.0 t/hm^(2)),NP(36.7 t/hm^(2)),PK(36.4 t/hm^(2))and CK(34.1 t/hm^(2)).The sugar to acid ratio(S:A)was the highest(10.9)in 2012,and the soluble sugar increased by 15.7%after four-year NPKM fertilization.The NPKM fertilization also significantly increased the vitamin C,soluble solid and firmness.The soil organic carbon contents at 0-20 cm,20-40 cm and 40-60 cm in depth under the NPKM treatment were 27%,29%and 139%higher than that of the CK treatment,respectively.The available N contents at 0-20 cm,20-40 cm and 40-60 cm in depth in the 1.5NPK treatment were 180%,114%and 133%higher than that in the CK treatment,respectively.Balanced fertilization with N,P,K and organic manure is important to soil fertility,which may increase yield and improve quality in field-grown kiwifruit orchard.Zhao Zuoping Duan Min Yan Sha Liu Zhifeng Wang Qi Fu Jing Tong Yan’an 2017International Journal of Agricultural and Biological Engineering2017,10,2:6

12Integrating full-length transcriptomics and metabolomics reveals the regulatory mechanisms underlying yellow pigmentation in tree peony(Paeonia suffruticosa Andr.)flowers显示文摘Tree peony(Paeonia suffruticosa Andr.)is a popular ornamental plant in China due to its showy and colorful flowers.However,yellow-colored flowers are rare in both wild species and domesticated cultivars.The molecular mechanisms underlying yellow pigmentation remain poorly understood.Here,petal tissues of two tree peony cultivars,“High Noon”(yellow flowers)and“Roufurong”(purple–red flowers),were sampled at five developmental stages(S1–S5)from early flower buds to full blooms.Five petal color indices(brightness,redness,yellowness,chroma,and hue angle)and the contents of ten different flavonoids were determined.Compared to“Roufurong,”which accumulated abundant anthocyanins at S3–S5,the yellow-colored“High Noon”displayed relatively higher contents of tetrahydroxychalcone(THC),flavones,and flavonols but no anthocyanin production.The contents of THC,flavones,and flavonols in“High Noon”peaked at S3 and dropped gradually as the flower bloomed,consistent with the color index patterns.Furthermore,RNA-seq analyses at S3 showed that structural genes such as PsC4Hs,PsDFRs,and PsUFGTs in the flavonoid biosynthesis pathway were downregulated in“High Noon,”whereas most PsFLSs,PsF3Hs,and PsF3’Hs were upregulated.Five transcription factor(TF)genes related to flavonoid biosynthesis were also upregulated in“High Noon.”One of these TFs,PsMYB111,was overexpressed in tobacco,which led to increased flavonols but decreased anthocyanins.Dual-luciferase assays further confirmed that PsMYB111 upregulated PsFLS.These results improve our understanding of yellow pigmentation in tree peony and provide a guide for future molecular-assisted breeding experiments in tree peony with novel flower colors.Xiaoning Luo Daoyang Sun Shu Wang Sha Luo Yaqi Fu Lixin Niu Qianqian Shi Yanlong Zhang 2021Horticulture Research2021,8,1:5
13Redirecting differentiation of mammary progenitor cells by 3D bioprinted sweat gland microenvironment显示文摘Background:Mammary progenitor cells(MPCs)maintain their reproductive potency through life,and their specific microenvironments exert a deterministic control over these cells.MPCs provides one kind of ideal tools for studying engineered microenvironmental influence because of its accessibility and continually undergoes postnatal developmental changes.The aim of our study is to explore the critical role of the engineered sweat gland(SG)microenvironment in reprogramming MPCs into functional SG cells.Methods:We have utilized a three-dimensional(3D)SG microenvironment composed of gelatin-alginate hydrogels and components from mouse SG extracellular matrix(SG-ECM)proteins to reroute the differentiation of MPCs to study the functions of this microenvironment.MPCs were encapsulated into the artificial SG microenvironment and were printed into a 3D cell-laden construct.The expression of specific markers at the protein and gene levels was detected after cultured 14 days.Results:Compared with the control group,immunofluorescence and gene expression assay demonstrated that MPCs encapsulated in the bioprinted 3D-SG microenvironment could significantly express the functional marker of mouse SG,sodium/potassium channel protein ATP1a1,and tend to express the specific marker of luminal epithelial cells,keratin-8.When the Shh pathway is inhibited,the expression of SG-associated proteins in MPCs under the same induction environment is significantly reduced.Conclusions:Our evidence proved the ability of differentiated mouse MPCs to regenerate SG cells by engineered SG microenvironment in vitro and Shh pathway was found to be correlated with the changes in the differentiation.These results provide insights into regeneration of damaged SG by MPCs and the role of the engineered microenvironment in reprogramming cell fate.Rui Wang Yihui Wang Bin Yao Tian Hu Zhao Li Yufan Liu Xiaoli Cui Liuhanghang Cheng Wei Song Sha Huang Xiaobing Fu 2019Burns & Trauma2019,7,1:5

15Precipitation under Subtropical High Conditions:Evidence and Implications显示文摘The impact of the subtropical high (STH) on precipitation was investigated on a daily timescale using matched NCEP and the Global Precipitation Climatology Project (GPCP) datasets.Comparison of the conditional probability (intensity) of precipitation under STH condi-tions with that under non-STH conditions suggests that the presence of the STH conditions has a limited impact on local precipitation.In the West Pacific Subtropical High (WPSH) and the North Atlantic Subtropical High (NASH),precipitation was only 30% lower under STH conditions than under non-STH conditions.The STH conditions had somewhat more impact on precipitation intensity,but it was still 50% less than the intensity under non-STH conditions (mean of roughly 5 mm d 1).Pre-cipitation under STH conditions was found to be highly correlated with vertical motion.Active updrafts occurring even under STH conditions are essential for frequent oc-currences and moderate intensities of precipitation.FENG Sha LIU Qi FU Yun-Fei 2009Atmospheric and Oceanic Science Letters2009,2,4:4
16Tumorigenic bacteria in colorectal cancer:mechanisms and treatments显示文摘Colorectal cancer(CRC)is the third most common and the second most fatal cancer.In recent years,more attention has been directed toward the role of gut microbiota in the initiation and development of CRC.Some bacterial species,such as Fusobacterium nucleatum,Escherichia coli,Bacteroides fragilis,Enterococcus faecalis,and Salmonella sp.have been associated with CRC,based upon sequencing studies in CRC patients and functional studies in cell culture and animal models.These bacteria can cause host DNA damage by genotoxic substances,including colibactin secreted by pks+Escherichia coli,B.fragilis toxin(BFT)produced by Bacteroides fragilis,and typhoid toxin(TT)from Salmonella.These bacteria can also indirectly promote CRC by influencing host-signaling pathways,such as E-cadherin/β-catenin,TLR4/MYD88/NF-κB,and SMO/RAS/p38 MAPK.Moreover,some of these bacteria can contribute to CRC progression by helping tumor cells to evade the immune response by suppressing immune cell function,creating a proinflammatory environment,or influencing the autophagy process.Treatments with the classical antibacterial drugs,metronidazole or erythromycin,the antibacterial active ingredients,M13@Ag(electrostatically assembled from inorganic silver nanoparticles and the protein capsid of bacteriophage M13),berberine,and zerumbone,were found to inhibit tumorigenic bacteria to different degrees.In this review,we described progress in elucidating the tumorigenic mechanisms of several CRC-associated bacteria,as well as progress in developing effective antibacterial therapies.Specific bacteria have been shown to be active in the oncogenesis and progression of CRC,and some antibacterial compounds have shown therapeutic potential in bacteria-induced CRC.These bacteria may be useful as biomarkers or therapeutic targets for CRC.Sha Li Jinyi Liu Xiangjin Zheng Liwen Ren Yihui Yang Wan Li Weiqi Fu Jinhua Wang Guanhua Du 2022Cancer Biology & Medicine2022,19,2:3
17Clinicopathologic characteristics and therapeutic responses of Chinese patients with non-small cell lung cancer who harbor an anaplastic lymphoma kinase rearrangement显示文摘Introduction: The rearrangement of the anaplastic lymphoma kinase(ALK) gene accounts for approximately 1%–6% of lung adenocarcinoma cases and deines a molecular subgroup of tumors characterized by clinical sensitivity to ALK inhibitors such as crizotinib. This study aimed to identify the relationship between ALK rearrangement and the clinico?pathologic characteristics of non?small cell lung cancer(NSCLC) and to analyze the therapeutic responses of crizotinib and conventional chemotherapy to ALK rearrangement in NSCLC patients.Methods: A total of 487 lung cancer patients who underwent testing for ALK rearrangement in our department were included in this study. ALK rearrangement was examined by using fluorescence in situ hybridization(FISH) assay.Results: Among the 487 patients, 44(9.0%) were diagnosed with ALK rearrangement by using FISH assay. In 123 patients with adenocarcinoma who were non?smokers and of a young age(≤58 years old), the frequency of ALK rearrangement was 20.3%(25/123). Short overall survival(OS) was associated with non?adenocarcinoma tumor type(P = 0.006), poorly diferentiated tumors(P al growth factor rece= 0.001), advanced?stage tumors(P < 0.001), smoking history(P ptor(EGFR)(P = 0.008), and wild?type epidermrter time to cancer p= 0.008). Moreover, patients with poorly diferentiated and advanced?stage tumors had a shorogression compared with those with well diferentiated(P = 0.023) and early?stage tumors(P = 0.001), respectively.Conclusions: ALK?rearranged NSCLC tends to occur in younger individuals who are either non?smokers or light smokers with adenocarcinoma. Patients with ALK rearrangement might beneit from ALK inhibitor therapy.Sha Fu Hai‑Yun Wang Fang Wang Ma‑Yan Huang Ling Deng Xiao Zhang Zu‑Lu Ye Jian‑Yong Shao 2015Chinese Journal of Cancer2015,34,9:3
183D-printable supramolecular hydrogels with shear-thinning property: fabricating strength tunable bioink via dual crosslinking显示文摘3-dimensional(3D)bioprinting technology provides promising strategy in the fabrication of artificial tissues and organs.As the fundamental element in bioprinting process,preparation of bioink with ideal mechanical properties without sacrifice of biocompatibility is a great challenge.In this study,a supramolecular hydrogel-based bioink is prepared by polyethylene glycol(PEG)grafted chitosan,α-cyclodextrin(α-CD)and gelatin.It has a primary crosslinking structure through the aggregation of the pseudo-polyrotaxane-like side chains,which are formed from the host-guest interactions betweenα-CD and PEG side chain.Apparent viscosity measurement shows the shear-shinning property of this bioink,which might be due to the reversibility of the physical crosslinking.Moreover,withβ-glycerophosphate at different concentrations as the secondary crosslinking agent,the printed constructs demonstrate different Young's modulus(p<0.001).They could also maintain the Young's modulus in cell culture condition for at least 21 days(p<0.05).By co-culturing each component with fibroblasts,CCK-8 assay demonstrate cellular viability is higher than 80%.After bioprinting and culturing,immunofluorescence staining with quantification indicate the expression of Ki-67,Paxillin,and N-cadherin is higher in day 14 than those in day 3(p<0.05).Oil red O and Nissl body specific staining reflect strength tunable bioink may have impact on the cell fate of mesenchymal stem cells(p<0.05).This work might provide new idea for advanced bioink in the application of re-establishing complicated tissues and organs.Tian Hu Xiaoliang Cui Meng Zhu Man Wu Ye Tian Bin Yao Wei Song Zhongwei Niu Sha Huang Xiaobing Fu 2020Bioactive Materials2020,5,4:3
19Benzimidazoles induce concurrent apoptosis and pyroptosis of human glioblastoma cells via arresting cell cycle显示文摘Glioblastoma multiforme(GBM)is the most malignant and lethal primary brain tumor in adults accounting for about 50%of all gliomas.The only treatment available for GBM is the drug temozolomide,which unfortunately has frequent drug resistance issue.By analyzing the hub genes of GBM via weighted gene co-expression network analysis(WGCNA)of the cancer genome atlas(TCGA)dataset,and using the connectivity map(CMAP)platform for drug repurposing,we found that multiple azole compounds had potential anti-GBM activity.When their anti-GBM activity was examined,however,only three benzimidazole compounds,i.e.flubendazole,mebendazole and fenbendazole,potently and dose-dependently inhibited proliferation of U87 and U251 cells with IC50 values below 0.26μM.Benzimidazoles(0.125−0.5μM)dose-dependently suppressed DNA synthesis,cell migration and invasion,and regulated the expression of key epithelial-mesenchymal transition(EMT)markers in U87 and U251 cells.Benzimidazoles treatment also dose-dependently induced the GBM cell cycle arrest at the G2/M phase via the P53/P21/cyclin B1 pathway.Furthermore,the drugs triggered pyroptosis of GBM cells through the NF-κB/NLRP3/GSDMD pathway,and might also concurrently induced mitochondria-dependent apoptosis.In a nude mouse U87 cell xenograft model,administration of flubendazole(12.5,25,and 50 mg·kg^(−1)·d^(−1),i.p,for 3 weeks)dose-dependently suppressed the tumor growth without obvious adverse effects.Taken together,our results demonstrated that benzimidazoles might be promising candidates for the treatment of GBM.Li-wen Ren Wan Li Xiang-jin Zheng Jin-yi Liu Yi-hui Yang Sha Li Sen Zhang Wei-qi Fu Bin Xiao Jin-hua Wang Guan-hua Du 2022Acta Pharmacologica Sinica2022,43,1:3
20A Distributed Approach of Big Data Mining for Financial Fraud Detection in a Supply Chain显示文摘Supply Chain Finance(SCF)is important for improving the effectiveness of supply chain capital operations and reducing the overall management cost of a supply chain.In recent years,with the deep integration of supply chain and Internet,Big Data,Artificial Intelligence,Internet of Things,Blockchain,etc.,the efficiency of supply chain financial services can be greatly promoted through building more customized risk pricing models and conducting more rigorous investment decision-making processes.However,with the rapid development of new technologies,the SCF data has been massively increased and new financial fraud behaviors or patterns are becoming more covertly scattered among normal ones.The lack of enough capability to handle the big data volumes and mitigate the financial frauds may lead to huge losses in supply chains.In this article,a distributed approach of big data mining is proposed for financial fraud detection in a supply chain,which implements the distributed deep learning model of Convolutional Neural Network(CNN)on big data infrastructure of Apache Spark and Hadoop to speed up the processing of the large dataset in parallel and reduce the processing time significantly.By training and testing on the continually updated SCF dataset,the approach can intelligently and automatically classify the massive data samples and discover the fraudulent financing behaviors,so as to enhance the financial fraud detection with high precision and recall rates,and reduce the losses of frauds in a supply chain.Hangjun Zhou Guang Sun Sha Fu Xiaoping Fan Wangdong Jiang Shuting Hu Lingjiao Li 2020Computers, Materials & Continua2020,,8:3
