| 1 | Hidden policy ciphertext-policy attribute-based encryption with keyword search against keyword guessing attack显示文摘Attribute-based encryption with keyword search(ABKS) enables data owners to grant their search capabilities to other users by enforcing an access control policy over the outsourced encrypted data. However,existing ABKS schemes cannot guarantee the privacy of the access structures, which may contain some sensitive private information. Furthermore, resulting from the exposure of the access structures, ABKS schemes are susceptible to an off-line keyword guessing attack if the keyword space has a polynomial size. To solve these problems, we propose a novel primitive named hidden policy ciphertext-policy attribute-based encryption with keyword search(HP-CPABKS). With our primitive, the data user is unable to search on encrypted data and learn any information about the access structure if his/her attribute credentials cannot satisfy the access control policy specified by the data owner. We present a rigorous selective security analysis of the proposed HP-CPABKS scheme, which simultaneously keeps the indistinguishability of the keywords and the access structures. Finally,the performance evaluation verifies that our proposed scheme is efficient and practical. | Shuo QIU Jiqiang LIU Yanfeng SHI Rui ZHANG | 2017 | Science China(Information Sciences)2017，60，5： | 18 |

| 3 | A high-strength mineralized collagen bone scaffold for large-sized cranial bone defect repair in sheep显示文摘Large-sized cranial bone defect repair presents a great challenge in the clinic.The ideal cranioplasty materials to realize the functional and cosmetic recovery of the defect must have sufficient mechanical support,excellent biocompatibility,good osseointegration and biodegradability as well.In this study,a high-strength mineralized collagen(MC)bone scaffold was developed with biomimetic composition,microstructure and mechanical properties for the repair of sheep largesized cranial bone defects in comparison with two traditional cranioplasty materials,polymethyl methacrylate and titanium mesh.The compact MC scaffold showed no distinct pore structure and therefore possessed good mechanical properties.The strength and elastic modulus of the scaffold were much higher than those of natural cancellous bone and slightly lower than those of natural compact bone.In vitro cytocompatibility evaluation revealed that the human bone marrow mesenchymal stem cells(hBMSC)had good viability,attachment and proliferation on the compact MC scaffold indicating its excellent biocompatibility.An adult sheep cranial bone defect model was constructed to evaluate the performances of these cranioplasty materials in repairing the cranial bone defects.The results were investigated by gross observation,computed tomography scanning as well as histological assessments.The in vivo evaluations indicated that compact MC scaffold showed notable osteoconductivity and osseointegration with surrounding cranial bone tissues by promoting bone regeneration.Our results suggested that the compact MC scaffold has a promising potential for large-sized cranial bone defect repair. | Shuo Wang Zhijun Zhao Yongdong Yang Antonios G.Mikos Zhiye Qiu Tianxi Song Fuzhai Cui XiumeiWang Chunyang Zhang | 2018 | Regenerative Biomaterials2018，5，5： | 9 |
| 4 | Mutation profile and its correlation with clinicopathology in Chinese hepatocellular carcinoma patients显示文摘Background:Hepatocellular carcinoma(HCC)is one of the most common causes of cancer worldwide.Although many studies have focused on oncogene characteristics,the genomic landscape of Chinese HCC patients has not been fully clarified.Methods:A total of 165 HCC patients,including 146 males and 19 females,were enrolled.The median age was 55 years(range,27-78 years).Corresponding clinical and pathological information was collected for further analysis.A total of 168 tumor tissues from these patients were selected for next-generation sequencing(NGS)-based 450 panel gene sequencing.Genomic alterations including single nucleotide variations(SNV),short and long insertions and deletions(InDels),copy number variations,and gene rearrangements were analyzed.Tumor mutational burden(TMB)was measured by an algorithm developed in-house.The top quartile of HCC was classified as TMB high.Results:A total of 1,004 genomic alterations were detected from 258 genes in 168 HCC tissues.TMB values were identified in 160 HCC specimens,with a median TMB of 5.4 Muts/Mb(range,0-28.4 Muts/Mb)and a 75%TMB of 7.7 Muts/Mb.The most commonly mutated genes were TP53,TERT,CTNNB1,AXIN1,RB1,TSC2,CCND1,ARID1A,and FGF19.SNV was the most common mutation type and C:G>T:A and guanine transformation were the most common SNVs.Compared to wild-type patients,the proportion of Edmondson grade III-IV and microvascular invasion was significantly higher in TP53 mutated patients(P<0.05).The proportion of tumors invading the hepatic capsule was significantly higher in TERT mutated patients(P<0.05).The proportion of Edmondson grade I-II,alpha fetoprotein(AFP)<25μmg/L,and those without a history of hepatitis B was significantly higher in CTNNB1 mutated patients(P<0.05).CTNNB1 mutations were associated with TMB high in HCC patients(P<0.05).Based on correlation analysis,the mutation of TP53 was independently correlated with microvascular invasion(P=0.002,OR=3.096)and Edmondson grade III-IV(P=0.008,OR=2.613).The mutation of TERT was independently correlated with tumor invasion of the liver capsule(P=0.001,OR=3.030),and the mutation of CTNNB1 was independently correlated with AFP(<25μmg/L)(P=0.009,OR=3.414).Conclusions:The most frequently mutated genes of HCC patients in China were TP53,TERT,and CTNNB1,which mainly lead to the occurrence and development of HCC by regulating the P53 pathway,Wnt pathway,and telomere repair pathway.There were more patients with microvascular invasion and Edmondson III-IV grade in TP53 mutated patients and more patients with hepatic capsule invasion in TERT mutated patients,while in CTNNB1 mutated patients,there were more patients with Edmondson I-II grade,AFP<25μmg/L,and a non-hepatitis B background.Also,the TMB values were significantly higher in CTNNB1 mutated patients than in wild type patients. | Shuo Wang Huasheng Shi Tao Liu Manjiang Li Sanshun Zhou Xuan Qiu Zusen Wang Weiyu Hu Weidong Guo Xiaoqian Chen Honglin Guo Xiaoliang Shi Junping Shi Yunjin Zang Jingyu Cao Liqun Wu | 2021 | Hepatobiliary Surgery and Nutrition2021，10，2： | 8 |
| 5 | NMDA Receptor Antagonist MK801 Protects Against 1-Bromopropane-Induced Cognitive Dysfunction显示文摘Occupational exposure to 1-bromopropane(1-BP) induces learning and memory deficits. However, no therapeutic strategies are currently available. Accumulating evidence has suggested that N-methyl-D-aspartate receptors(NMDARs) and neuroinflammation are involved in the cognitive impairments in neurodegenerative diseases. In this study we aimed to investigate whether the noncompetitive NMDAR antagonist MK801 protects against 1-BPinduced cognitive dysfunction. Male Wistar rats were administered with MK801(0.1 mg/kg) prior to 1-BP intoxication(800 mg/kg). Their cognitive performance was evaluated by the Morris water maze test. The brains of rats were dissected for biochemical, neuropathological,and immunological analyses. We found that the spatial learning and memory were significantly impaired in the1-BP group, and this was associated with neurodegeneration in both the hippocampus(especially CA1 and CA3)and cortex. Besides, the protein levels of phosphorylated NMDARs were increased after 1-BP exposure. MK801 ameliorated the 1-BP-induced cognitive impairments and degeneration of neurons in the hippocampus and cortex.Mechanistically, MK801 abrogated the 1-BP-induced disruption of excitatory and inhibitory amino-acid balance and NMDAR abnormalities. Subsequently, MK801 inhibited the microglial activation and release of pro-inflammatory cytokines in 1-BP-treated rats. Our findings, for the first time, revealed that MK801 protected against 1-BP-induced cognitive dysfunction by ameliorating NMDAR function and blocking microglial activation, which might provide a potential target for the treatment of 1-BP poisoning. | Lin Xu Xiaofei Qiu Shuo Wang Qingshan Wang Xiu-Lan Zhao | 2019 | Neuroscience Bulletin2019，35，2： | 8 |
| 6 | Role of prophylactic hyperthermic intraperitoneal chemotherapy in patients with locally advanced gastric cancer显示文摘BACKGROUND Gastric cancer is the second most common malignant tumor in China,ranking third among all malignant tumor mortality rates.Hyperthermic intraperitoneal chemotherapy(HIPEC)has been shown to increase significantly the effectiveness of intraperitoneal chemotherapeutic drugs,prolong the action time of these drugs on intraperitoneal tumor cells,and enhance their diffusion in tumor tissues.HIPEC may be one of the best choices for the eradication of residual cancer cells in the abdominal cavity.AIM The aim of this study was to study the role of preventive HIPEC after radical gastrectomy.METHODS A prospective analysis was performed with patients with c T4 N0-3 M0 gastric cancer to compare the effects of postoperative prophylactic HIPEC plus intravenous chemotherapy with those of routine adjuvant chemotherapy.Patients’medical records were analyzed,and differences in the peritoneal recurrence rate,diseasefree survival time,and total survival time between groups were examined.RESULTS The first site of tumor recurrence was the peritoneum in 11 cases in the conventional adjuvant chemotherapy group and in 2 cases in the HIPEC group(P=0.020).The 1-year and 3-year disease-free survival rates were 91.9%and 60.4%,respectively,in the conventional adjuvant chemotherapy group and 92.1%and 63.0%,respectively,in the HIPEC group.The 1-year and 3-year overall survival rates were 95.2%and 66.3%,respectively,in the conventional adjuvant chemotherapy group and 96.1%and 68.6%,respectively,in the HIPEC group.No significant difference in postoperative or chemotherapy complications was observed between groups.CONCLUSION In patients with c T4 N0-3 M0 gastric cancer,prophylactic HIPEC after radical tumor surgery is beneficial to reduce peritoneal tumor recurrence and prolong survival. | Tian-Yu Xie Di Wu Shuo Li Zhao-Yan Qiu Qi-Ying Song Da Guan Li-Peng Wang Xiong-Guang Li Feng Duan Xin-Xin Wang | 2020 | World Journal of Gastrointestinal Oncology2020，12，7： | 7 |
| 7 | Secondary metabolites of petri-dish cultured Antrodia camphorata and their hepatoprotective activities against alcohol-induced liver injury in mice显示文摘Antrodia camphorata, a well-known and highly valued edible medicinal mushroom with intriguing activities like liver protection, has been traditionally used for the treatment of alcoholic liver disease. A. camphorata shows highly medicinal and commercial values with the demand far exceeds the available supply. Thus, the petri-dish cultured A. camphorata(PDCA) is expected to develope as a substitute. In this paper, nineteen triterpenes were isolated from PDCA, and thirteen of them were the unique anthroic acids in A. camphorata, including the main content antcin K, which suggested that PDCA produced a large array of the same anthroic acids as the wild one. Furthermore, no obvious acute toxicity was found suggesting the edible safety of PDCA. In mice alcohol-induced liver injury model, triglyceride(TG), aspartate aminotransferase(AST), alanine aminotransferase(ALT), and malondialdehyde(MDA) had been reduced by the PDCA powder as well as the main content antcin K, which indicated that the PDCA could protect alcoholic liver injury in mice model and antcin K could be the effective component responsible for the hepatoprotective activities of PDCA against alcoholic liver diseases. | WU Yu TIAN Wen-Jing GAO Shuo LIAO Zu-Jian WANG Guang-Hui LO Jir-Mehng LIN Pei-Hsin ZENG De-Quan QIU Da-Ren LIU Xiang-Zhong ZHOU Mi LIN Ting CHEN Hai-Feng | 2019 | Chinese Journal of Natural Medicines2019，17，1： | 4 |
| 8 | A New Technique for Transvenous Embolization of Brain Arteriovenous Malformations in Hybrid Operation显示文摘To the Editor:Eliminating a nidus was deemed to be the key to curing brain arteriovenous malformations (bAVMs).When conducting interventional embolization,it was suggested to superselect the microcatheter close to the nidus before injecting embolic agents.The traditional embolization was conducted via arterial approaches,which required the accessibility of arterial feeders.Difficulties and risks increased in the cases with lesions with narrow calibers,tortuous courses,or 'en passage' arterial supplies.Transvenous approaches were proved to be safe and effective accesses in bAVM embolization without the limitations of arteries, The current transvenous approaches were established through femoral and cervical veins. | Ming-Ze Wang Han-Cheng Qiu Shuo Wang Yong Cao Meng Zhao Ji-Zong Zhao | 2018 | Chinese Medical Journal2018，，24： | 3 |

| 10 | Protein tyrosine kinase inhibitor resistance in malignant tumors:molecular mechanisms and future perspective显示文摘Protein tyrosine kinases(PTKs)are a class of proteins with tyrosine kinase activity that phosphorylate tyrosine residues of critical molecules in signaling pathways.Their basal function is essential for maintaining normal cell growth and differentiation.However,aberrant activation of PTKs caused by various factors can deviate cell function from the expected trajectory to an abnormal growth state,leading to carcinogenesis.Inhibiting the aberrant PTK function could inhibit tumor growth.Therefore,tyrosine kinase inhibitors(TKIs),target-specific inhibitors of PTKs,have been used in treating malignant tumors and play a significant role in targeted therapy of cancer.Currently,drug resistance is the main reason for limiting TKIs efficacy of cancer.The increasing studies indicated that tumor microenvironment,cell death resistance,tumor metabolism,epigenetic modification and abnormal metabolism of TKIs were deeply involved in tumor development and TKI resistance,besides the abnormal activation of PTK-related signaling pathways involved in gene mutations.Accordingly,it is of great significance to study the underlying mechanisms of TKIs resistance and find solutions to reverse TKIs resistance for improving TKIs efficacy of cancer.Herein,we reviewed the drug resistance mechanisms of TKIs and the potential approaches to overcome TKI resistance,aiming to provide a theoretical basis for improving the efficacy of TKIs. | Yang Yang Shuo Li Yujiao Wang Yi Zhao Qiu Li | 2022 | Signal Transduction and Targeted Therapy2022，7，10： | 1 |
| 11 | No tillage outperforms conventional tillage under arid conditions and following fertilization显示文摘Reduced tillage practices present a tool that could sustainably intensify agriculture.The existing literature,however,lacks a consensus on how and when reduced tillage practices should get implemented.We reanalyzed here an extensive dataset comparing how regular tillage practices(i.e.,conventional tillage)impacted yield of eight crops compared to stopping tillage altogether(i.e.,no-tillage practice).We observed that aridity and fertilization favored no tillage over conventional tillage whereas conventional tillage performed better under high fertility settings.We further show that the responses are consistent across the crops.Our reanalysis complements the original and fills a gap in the literature questioning the conditions under which reducing tillage presents a viable alternative to common tillage practices. | Stavros D.Veresoglou Junjiang Chen Xuheng Du Qi Fu QingLiu Geng Chenyan Huang Xilin Huang Nan Hu Yiming Hun Guolin C.Li Zhiman Lin Zhiyu Ma Yuyi Ou Shuo Qi Haitian Qin Yingbo Qiu Xibin Sun Ye Tao YiLing Tian Jie Wang Lingxiao Wu Ziwei Wu Siqi Xie Ao Yang Dan Yang Chen Zeng Ying Zeng RuJie Zhang | 2023 | Soil Ecology Letters2023，5，1： | 1 |
| 12 | Enhanced room-temperature Naþionic conductivity in Na_(4.92)Y_(0.92)Zr_(0.08)Si_(4)O_(12)显示文摘Developing cost-effective and reliable solid-state sodium batteries with superior performance is crucial for stationary energy storage.A key component in facilitating their application is a solid-state electrolyte with high conductivity and stability.Herein,we employed aliovalent cation substitution to enhance ionic conductivity while preserving the crystal structure.Optimized substitution of Y^(3+)with Zr^(4+)in Na_(5)YSi_(4)O_(12) introduced Naþion vacancies,resulting in high bulk and total conductivities of up to 6.5 and 3.3 mS cm^(-1),respectively,at room temperature with the composition Na_(4.92)Y_(0.92)Zr_(0.08)Si_(4)O_(12)(NYZS).NYZS shows exceptional electrochemical stability(up to 10 V vs.Naþ/Na),favorable interfacial compatibility with Na,and an excellent critical current density of 2.4 mA cm^(-2).The enhanced conductivity of Naþions in NYZS was elucidated using solid-state nuclear magnetic resonance techniques and theoretical simulations,revealing two migration routes facilitated by the synergistic effect of increased Naþion vacancies and improved chemical environment due to Zr^(4+)substitution.NYZS extends the list of suitable solid-state electrolytes and enables the facile synthesis of stable,low-cost Naþion silicate electrolytes. | Aikai Yang Kai Yao Mareen Schaller Enkhtsetseg Dashjav Hang Li Shuo Zhao Qiu Zhang Martin Etter Xingchen Shen Huimin Song Qiongqiong Lu Ruijie Ye Igor Moudrakovski Quanquan Pang Sylvio Indris Xingchao Wang Qianli Ma Frank Tietz Jun Chen Olivier Guillon | 2023 | eScience2023，3，6： | 0 |
| 13 | Anticonvulsant Effect of Xingnaojing Injection on Acute Seizure Models in Mice显示文摘Background:Epilepsy is characterized by acute recurrent seizures.The control of seizures is largely hampered by the tolerance to current anti-seizure drugs.Complementary anti-convulsant pharmacotherapies are urgently needed.Objective:Here,we aimed to investigate the anti-convulsant effects of Xingnaojing Injection(XNJ)which is an approved Traditional Chinese Medicine injection on different acute seizure models in mice.Methods:The effects of XNJ were tested on the maximal electroshock(MES),pentylenetetrazol(PTZ)and kainic acid(KA)acute seizure models.Also,whether XNJ can directly inhibit hippocampal neuronal firings were exam-ined by in vitro electrophysiology.Results:XNJ could shorten the durations of generalized tonic-clonic seizures in the MES model.It also significantly prolonged the latencies to generalized myo-clonic seizures in the PTZ model.In the KA model,XNJ showed various efficacies including inhibiting the seizure stages,prolonging the latency to the occurrence of the first seizures or generalized seizures,shortening the seizure durations,decreasing the numbers of generalized seizures.In vitro electrophysiological recordings further verified XNJ directly inhibited both the spontaneous and evoked action potentials of hippocampal pyramidal neurons,but did not influence the excitatory or inhibitory synaptic transmissions.Conclusion:These findings proposed XNJ as an alternative anti-convulsant pharmacotherapy for controlling acute epileptic seizures. | Minjuan Sun Xiaoyun Qiu Zhijian Yuan Shuo Zhang Qi Zhang Xiaoli Da Xuming Ji Xuhong Jiang Cenglin Xu Zhong Chen | 2023 | Clinical Complementary Medicine and Pharmacology2023，3，3： | 0 |
| 14 | Biphasic mineralized collagen-based composite scaffold for cranial bone regeneration in developing sheep显示文摘Appropriate mechanical support and excellent osteogenic capability are two essential prerequisites of customized implants for regenerating large-sized cranial bone defect.Although porous bone scaffolds have been widely proven to promote bone regeneration,their weak mechanical properties limit the clinical applications in cranioplasty.Herein,we applied two previously developed mineralized collagen-based bone scaffolds(MC),porous MC(pMC)and compact MC(cMC)to construct a biphasic MC composite bone scaffold(bMC)to repair the large-sized cranial bone defect in developing sheep.A supporting frame composed of cMC phase in the shape of tic–tac–toe structure was fabricated first and then embedded in pMC phase.The two phases had good interfacial bond,attributing to the formation of an interfacial zone.The in vivo performance of the bMC scaffold was evaluated by using a cranial bone defect model in 1-month-old sheep.The computed tomography imaging,X-ray scanning and histological evaluation showed that the pMC phase in the bMC scaffold,similar to the pMC scaffold,was gradually replaced by the regenerative bone tissues with comprehensively increased bone mineral density and complete connection of bone bridge in the whole region.The cMC frame promoted new bone formation beneath the frame without obvious degradation,thus providing appropriate mechanical protection and ensuring the structural integrity of the implant.In general,the sheep with bMC implantation exhibited the best status of survival,growth and the repair effect.The biphasic structural design may be a prospective strategy for developing new generation of cranioplasty materials to regenerate cranial bone defect in clinic. | Jingchuan Zheng Zhijun Zhao Yongdong Yang Shuo Wang Yonggang Zhao Yang Xiong Shuhui Yang Zhiye Qiu Tianxi Song Chunyang Zhang Xiumei Wang | 2022 | Regenerative Biomaterials2022，9，1： | 0 |
| 15 | 106 New Emission-line Galaxies and 29 New Galactic HⅡ Regions are Identified with Spectra in the Unknown Data Set of LAMOST DR7显示文摘This work is to retrieve emission-line spectra from the“Unknown”data set in LAMOST DR7 V1.2,most of which are low signal-to-noise ratios spectra.In the work,we perform emission line search and redshift calculations on the Unknown data set to get possible emission line galaxy spectra.Taking the galaxy spectra released by LAMOST as templates,the Product Quantization(PQ)based approximate nearest neighbor(ANN)search is used to retrieve the nearest neighbors of each spectrum.We keep the spectra for which the calculated redshift and the published redshift of the template meet the threshold,and 16,188 spectra with emission lines are obtained from the LAMOST DR7 Unknown data set.After visual inspection of spectra 10,266 spectra are left,in which 5828 spectra are identified as emission-line galaxies,1782 spectra show ionization nebula features,and other 2656 are not clearly classified.Among 5828 spectra,5720 can be found in Strasbourg astronomical Data Center catalog,Sloan Digital Sky Survey catalog,or NASA/IPAC Extragalactic Database catalog.The 108 spectra(corresponding to 106unique coordinates of R.A.and decl.)which have no record in these three databases are new discoveries;for the1782 spectra showing ionization nebula features,most of them have radial velocities less than 150 kilometers per second.We check them with the latest version of WISE HⅡcatalog V2.0(short for HIICat V2)and 985 out of the1782 spectra belong to 72 HⅡregions.Of these HⅡregions,43 were previously identified while the other 29 are newly identified in this work including 797 newly observed spectra.Besides,there are still 2656 spectra that cannot be clearly classified although they have obvious emission lines and with small redshift.Finally,106 new emissionline galaxies and 29 new Galactic HⅡregions are identified,and we conclude that the ANN method sped up by the PQ algorithm is efficient in solving the problem of pairing spectra with massive data set to figure out their classes.We present our result at the link http://paperdata.china-vo.org/LY_paper/Work2/press Work2_last.zip. | Yan Lu A-Li Luo Li-Li Wang You-Fen Wang Yin-Bi Li Jin-Shu Han Li Qin Yan-Ke Tang Bo Qiu Shuo Zhang Jian-Nan Zhang Yong-Heng Zhao | 2022 | Research in Astronomy and Astrophysics2022，22，6： | 0 |
| 16 | Dietary Exposure to Fumonisins and Health Risk Assessment in the Sixth China Total Diet Study——China,2015-2020显示文摘Introduction:Fumonisins are a group of widespread mycotoxins mainly existing in staple foods.Their toxicological effects on humans cause worldwide public health threat.During 2015–2020,the 6th China Total Diet Study(TDS)was conducted to study the dietary exposure to fumonisins in the Chinese adult population.Methods:Fumonisins were analyzed by LCMS/MS in 288 composite dietary samples collected from 24 provincial-level administrative divisions.After combining the national consumption data with analytical results,estimated daily intakes(EDIs)were assessed and compared with health-based guide values(HBGV).Results:In the 6th China TDS,the highest fumonisin B(FBs)levels were found in staple foods/cereals among the 12 food categories.EDI of FBs was 104.9 ng/kg of body weight(bw)/day at the upper bound accounting 5.25% of the provisional maximum tolerable daily intake set by Joint Food and Agriculture Organization/World Health Organization Expert Committee on Food Additives.Among the 12 food categories,cereals and cereal products were the greatest contributor to FB exposure at 95%.Conclusion:Although the estimated exposure to FBs in the 6th China TDS were well below the HBGV for FBs in general,it was 2 times higher than the exposure in the 5th China TDS.Furthermore,the exposure to FB3 has increased remarkable and is worth further attention in China. | Shuo Zhang Shuang Zhou Bing Lyu Nannan Qiu Jingguang Li Yunfeng Zhao Yongning Wu | 2021 | China CDC weekly2021，3，29： | 0 |
| 17 | Multi-Party Identity-Based Symmetric Privacy-Preserving Matching with Cloud Storage显示文摘In this paper,we address the problem of multi-party privacy-preserving matching(PPM)over the encrypted data.We firstly construct an efficient identity-based re-encryption scheme like ElGmal(IBR-ElGmal)using combined public keys,which not only ensures the privacy of the information during the transmission process but also holds perfect multiplicative homomorphic property.Then we construct a multi-party identity-based symmetric privacy-preserving matching(M-IBSPM)protocol based on IBR-ElGmal scheme in cloud environments,which realizes the privacy-preserving matching among multiple different parties as well as getting the symmetric output.Furthermore,with our M-IBSPM protocol,most of the computation costs are taken over by cloud service provider without leaking any privacy,and our protocol achieves perfect security and privacy in the semi-honest model.Finally,we analyze the efficiency for our protocol. | QIU Shuo LIU Jiqiang SHI Yanfeng HAN Zhen | 2014 | Wuhan University Journal of Natural Sciences2014，19，5： | 0 |
| 18 | A new vegetation index combination for leaf carotenoid-tochlorophyll ratio: minimizing the effect of their correlation显示文摘The ratio of leaf carotenoid to chlorophyll(Car/Chl)is an indicator of vegetation photosynthesis,development and responses to stress.However,the correlation between Car and Chl,and their overlapping absorption in the visible spectral domain pose a challenge for optical remote sensing of their ratio.This study aims to investigate combinations of vegetation indices(VIs)to minimize the influence of Car-Chl correlation,thus being more sensitive to the variability in the ratio across vegetation species and sites.VIs sensitive to Car and Chl variability were combined into four candidates of combinations,using a simulated dataset from the PROSPECT model.The VI combinations were then tested using six simulated datasets with different Car-Chl correlations,and evaluated against four independent datasets.The ratio of the carotenoid triangle ratio index(CTRI)with the red-edge chlorophyll index(CIred-edge)was found least influenced by the Car-Chl correlation and demonstrated a superior ability for estimating Car/Chl variability.Compared with published VIs and two machine learning algorithms,CTRI/CIred-edge also showed the optimal performance in the fourfield datasets.This new VI combination could be useful to provide insights in spatiotemporal variability in the leaf Car/Chl ratio,applicable for assessing vegetation physiology,phenology,and response to environmental stress. | Chunmei He Jia Sun Yuwen Chen Lunche Wang Shuo Shi Feng Qiu Shaoqiang Wang Torbern Tagesson | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
| 19 | CuP_(2) as high-capacity and long-cycle-life anode for potassium-ion batteries显示文摘Metal phosphides have shown great potential for potassium-ion batteries because of their high theoretical specific capacity.Nevertheless,most of the metal phosphide anodes are plagued by rapid capacity decay(caused by the large volume changes during the discharge/charge process),which would restrict their further practical application.Herein,a chemically bonded CuP_(2)/C composite was prepared by a facile high-energy ball milling method.A potassium bis(trifluoromethanesulfonyl)imide(KFSI)-based electrolyte was adopted instead of a conventional KPF6-based electrolyte for the CuP_(2)/C composite anode.Benefiting from the synergistic effects of the formation of strong P-O-C chemical bonds and the KFSIbased electrolyte,the CuP_(2)/C composite anode exhibited high reversible capacity(451.4 mAh g^(-1) at50 mA g^(-1)),excellent rate performance(123.5 mAh g^(-1) at 1000 mA g^(-1)),and superior cycling stability(300 mAh g^(-1) after 100 cycles).This work paves the way for the development of high-performance CuP_(2) anode for potassium-ion batteries. | Lin Li Zhe Hu Yong Lu Shuo Zhao Qiu Zhang Qiannan Liu Zhenhua Yan Shu-Lei Chou | 2021 | Journal of Energy Chemistry2021，30，12： | 0 |
| 20 | Electraesalopsis beuteli gen. & sp. nov., the first lucanid beetle from the Cretaceous Burmese amber(Coleoptera: Scarabaeoidea)显示文摘Absract The first stag beetle found in Cretaceous Myanmar amber, Electraesalopsis beuteli Bai, Zhang & Qiu gen. & sp. nov., is described and illustrated on the basis of one well-preserved specimen. This specimen provides more detailed morphological characters compared with compression fossils, e.g. the highly setose antennae and the punctured elytra. However, the systematic position of the new genus is still questionable and we provisionally place it as Lucanidae incertae sedis. In addition, the discovery of Electraesalopsis Bai, Zhang & Qiu gen. nov. also indicates that there is very high biodiversity in Burmese amber. The new discoveries in future studies on Burmese amber will provide more information and improve our knowledge of biogeography and early evolution of the Lucanidae. | Tengfei Qiu Yuanyuan Lu Weiwei Zhang Shuo Wang Yuxia Yang Ming Bai | 2017 | Zoological Systematics2017，42，3： | 0 |
