| 1 | Characterization and properties of a Sr2Si5N8:Eu^2+-based light-conversion agricultural film显示文摘In this paper,the fracture surfaces of a light-conversion film were observed using a scanning electron microscope(SEM),and then,the fluorescence spectra and mechanical properties of the film were tested.The SEM results show that the average diameter of the light conversion agent is 500 nm.The results of the mechanical properties tests show that the tensile strengths of light-conversion film increase from9.86 to 12.16 MPa and that the strain at breakage increases from 2.37%to 2.75%.In addition,the application effects of the light-co nversion film were studied.The results indicate that plant height,length of the maximum leaf,width of the maximum leaf and breadth of the plants increase by 24.43%,15.30%,15.60%and 19.07%,respectively.The quality of Chinese flowering cabbages treated with the lightconversion film is superior,including a 9.09%increase in the soluble protein content,a 21.27%increase in the polyphenol content,and a 19.15%increase in the soluble sugar content.Based on these results,light-conversion films can be applied in agricultural production. | Weibin Wu Zhenbang Zhang Riyue Dong Gening Xie Jianxian Zhou Kejue Wu Haonan Zhang Qianpei Cai Bingfu Lei | 2020 | Journal of Rare Earths2020，38，5： | 7 |
| 2 | Structural isomer and high-yield of Pt1Ag28 nanoduster via one-pot chemical wet method显示文摘In order to understand the structure-property correlation and explore the application of metal nanoclusters, it is important and intriguing to determine their crystal structure and obtain high-yield. At the same time, this is also a challenge in nanoscience and technology. Here, we report the highly efficient synthesis of Pt1Ag28 nanocluster via one-pot chemical wet method. The crystal structure of Pt1Ag28 nanocluster was determined by X-ray crystallography to be a face centered cubic (FCC) kernel. This novel structure is the structural isomerization of Pt1Ag28 nanocluster reported before. This phenomenon is first discovered in the synthesis of alloy nanoclusters. In addition, Pt1Ag28 nanocluster has high yield and exhibits potential optics in the near infrared (NIR) fluorescent imaging. The time-dependent density functional theory (TD-DFT) calculation implied that the optical property of Pt1Ag28 was sensitive to its structure. This work provides a simple method to synthesize alloy nanoclusters with structural isomerization. | Xinzhang Lin Chao Liu Keju Sun Ren'an Wu Xuemei Fu Jiahui Huang | 2019 | Nano Research2019，12，2： | 1 |

| 8 | Deep density estimation via invertible block-triangular mapping显示文摘In this work,we develop an invertible transport map,called KRnet,for density estimation by coupling the Knothe–Rosenblatt(KR)rearrangement and the flow-based generative model,which generalizes the real-valued non-volume preserving(real NVP)model(arX-iv:1605.08803v3).The triangular structure of the KR rearrangement breaks the symmetry of the real NVP in terms of the exchange of information between dimensions,which not only accelerates the training process but also improves the accuracy significantly.We have also introduced several new layers into the generative model to improve both robustness and effectiveness,including a reformulated affine coupling layer,a rotation layer and a component-wise nonlinear invertible layer.The KRnet can be used for both density estimation and sample generation especially when the dimensionality is relatively high.Numerical experiments have been presented to demonstrate the performance of KRnet. | Keju Tang Xiaoliang Wan Qifeng Liao | 2020 | Theoretical & Applied Mechanics Letters2020，10，3： | 1 |

| 10 | One-step rapid synthesis,crystal structure and 3.3 microseconds long excited-state lifetime of Pd1Ag28 nanocluster显示文摘Doping foreign atom(s)in metal nanoclusters is an effective strategy to engineer the properties and functionalities of metal nanoclusters.However,until now,to dope Pd atom into Ag nanoclusters remains a huge challenge.Here we develop a one-step rapid method to synthesize the Pd-doped Ag nanocluster with high yield.The prepared Pd1Ag28 nanocluster was characterized by mass spectroscopy,X-ray photoelectron spectroscopy,X-ray crystallography,fluorescence spectroscopy,ultraviolet-visible absorption spectroscopy and transient absorption spectroscopy.The nanocluster exhibits a perfect face-centered cubic(FCC)kernel structure with a tetrahedron-like shell.Of note,Pd1Ag28 nanocluster had an unexpectedly long excited-state lifetime of 3.3 microseconds,which is the longest excited-state lifetime for Ag-based nanoclusters S0 far.Meanwhile,the excellent near-infrared luminescence indicated the nanocluster has the potential in fluorescent bio-imaging.Besides,it was revealed that Pd1Ag28 nanocluster could be transformed into Au1Ag28 nanocluster via ion exchange reaction of AuPPhzCl with Pd1Ag28 nanocluster.This work provides an efficient synthetic protocol of alloy nanoclusters and wil contribute to study the effect of foreign atom on the properties of metal nanoclusters. | Xinzhang Lin Hengjiang Cong Keju Sun Xuemei Fu Wanchao Kang Xiuli Wang Shengye Jin Ren'an Wu Chao Liu Jiahui Huang | 2020 | Nano Research2020，13，2： | 1 |
| 11 | Resistance reduction of patterned surface inspired by cuticle structure of Achalinus spinalis显示文摘The crawling process of snakes is known to have fascinating tribological phenomena,whereas investigations on their frictional properties depending on patterned cuticles are insufficient.In this study,we have designed and fabricated biomimetic microstructures inspired by the geometric microunits of Achalinus spinalis cuticle using polyurethane acrylate(PUA)material and performed its tribological analysis.The micro-morphology of this Achalinus-inspired textured polymer surface(AITPS)is characterized by the closely and evenly quasi-rectangular microgrooves,periodically arranged along certain orientations.We have compared the frictional performance of our fabricated AITPS with other competitive microstructure,using a smooth steel ball and commercial clay as an interacting surface.After performing massive friction tests with steel ball and clay,AITPS still maintains good resistance reduction performed compared to the patterned surface with straight microgrooves,which is most likely due to the reduction of actual contact areas at the frictional interface. | Jiahui ZHAO Keju JI Qin CHEN Muhammad Niaz KHAN Chongwen TU Ze MA Jianming WU Jian CHEN Zhendong DAI | 2023 | Friction2023，11，7： | 0 |
| 12 | A proactive secret sharing scheme based on Chinese remainder theorem显示文摘If an adversary tries to obtain a secret s in a(t,n)threshold secret sharing(SS)scheme,it has to capture no less than t shares instead of the secret s directly.However,if a shareholder keeps a fixed share for a long time,an adversary may have chances to filch some shareholders’shares.In a proactive secret sharing(PSS)scheme,shareholders are supposed to refresh shares at fixed period without changing the secret.In this way,an adversary can recover the secret if and only if it captures at least t shares during a period rather than any time,and thus PSS provides enhanced protection to long-lived secrets.The existing PSS schemes are almost based on linear SS but no Chinese Remainder Theorem(CRT)-based PSS scheme was proposed.This paper proposes a PSS scheme based on CRT for integer ring to analyze the reason why traditional CRT-based SS is not suitable to design PSS schemes.Then,an ideal PSS scheme based on CRT for polynomial ring is also proposed.The scheme utilizes isomorphism of CRT to implement efficient share refreshing. | Keju MENG Fuyou MIAO Yu NING Wenchao HUANG Yan XIONG Chin-Chen CHANG | 2021 | Frontiers of Computer Science2021，15，2： | 0 |
| 13 | Neurotransmitters affecting time perception显示文摘BACKGROUND: It has been demonstrated that dopamine and acetylcholine are the main neurotransmitters that affect time perception, which is also affected by other neurotransmitters. OBJECTIVE: To summarize how the neurotransmitter affect the time perception, and put forward the perspectives for further study on time perception. RETRIEVE STRATEGY: An online search for related literatures published in English was conducted in Elsevier SDOL (ScienceDirect Online) database from May 1990 to March 2007 using key words of 'timing neurotransmitter'. Totally 69 literatures were collected, and they were primarily checked. Inclusive criteria: Reviews and experimental studies; correlative studies of timing neurotransmitter. Exclusive criteria: Repeated studies. LITERATURE EVALUATION: The literatures were mainly sourced from Cognitive Brain Research and Neuroscience, and they were analyzed according to the inclusive criteria. Nineteen of them were involved, and all were experimental studies and reviews. DATA SYNTHESIS: The studies on time perception are developed mainly concentrating on dopamine and acetylcholine. Dopamine D2 receptors mainly affect the speed of internal clock. Dopamine receptors play an important role in both timing excitation and inhibition, which suggests the bi-directional regulation of dopamine. Injection of dopamine agonist can affect the attention to timing information. Injection of BW813U (antagonist of acetylcholine) can induce memory disorder, which indicates the effect of acetylcholine on timing memory, and further study shows that it is the effect of acetylcholine in precentral medial area. In a word, the study on the neurotransmitters affecting time perception is still at the primary stage. CONCLUSION: Dopamine and acetylcholine are the neurotransmitters known to be related to time perception. Dopamine in the basal ganglia is related to internal-clock in the range of seconds and minutes; Acetylcholine in prefrontal cortex is related to the mechanisms of temporal memory and attention. Studies of neurotransmitter provide an approach to acknowledge on the neuromechanism of time perception. | Keju Wan Zhijie Zhang | 2007 | Neural Regeneration Research2007，2，12： | 0 |
| 14 | An integrated bioinformatics analysis and experimental study identified key biomarkers CD300A or CXCL1,pathways and immune infiltration in diabetic nephropathy mice显示文摘Diabetic nephropathy(DN)is a common microvascular complication that easily leads to end-stage renal disease.It is important to explore the key biomarkers andmolecular mechanisms relevant to diabetic nephropathy(DN).We used highthroughput RNA sequencing to obtain the genes related to DN glomerular tissues and healthy glomerular tissues of mice.Then we used LIMMA to analyze differentially expressed genes(DEGs)between DN and non-diabetic glomerular samples.And we performed KEGG,gene ontology functional(GO)enrichment,and gene set enrichment analysis to reveal the signaling pathway of the disease.The CIBERSORT algorithm based on support vector machine was used to determine the immune infiltration score.Random forest algorithm and Cytoscape obtained hub genes.Finally,we applied co-staining,immunohistochemical staining,RT-qPCR and western blotting to validate the protein and mRNA expression of both hub genes.We obtained 913 DEGs mainly related to inflammatory factors and immunity.GSEA results showed that differential genes were mainly enriched in IL-17 signaling pathway,lipid and atherosclerosis,rheumatoid arthritis,TNF signaling pathway,neutrophil extracellular trap formation,Staphylococcus aureus infection and other pathways.The intersection of the random forest algorithm and Cytoscape revealed both hub genes of CD300A and CXCL1.Experiments have shown that the both key genes of CD300A and CXCL1 shown increased expression in glomerular podocytes,and are related to the inflammation of diabetic nephropathy.And immunohistochemical staining and RT-qPCR further confirmed that the protein and mRNA expression level of CD300A or CXCL1 in glomeruli tissue in DN mice were increased.The expression levels of CD300A and CXCL1 increased significantly under HG(high glucose)stimulation,further confirming that diabetes can lead to increased levels of CD300A and CXCL1 at the cellular level.Through bioinformatics analysis,machine learning algorithms,and experimental research,CD300A and CXCL1 are confirmed as both potential biomarkers in diabetic nephropathy.And we further revealed the main pathways of differential genes and the differentially distributed immune infiltrating cells in diabetic nephropathy. | WEI LIANG QIANG LUO ZONGWEI ZHANG KEJU YANG ANKANG YANG QINGJIA CHI HUAN HU | 2022 | BIOCELL2022，46，8： | 0 |

| 16 | Genetic algorithm-optimized backpropagation neural network establishes a diagnostic prediction model for diabetic nephropathy:Combined machine learning and experimental validation in mice显示文摘Background:Diabetic nephropathy(DN)is the most common complication of type 2 diabetes mellitus and the main cause of end-stage renal disease worldwide.Diagnostic biomarkers may allow early diagnosis and treatment of DN to reduce the prevalence and delay the development of DN.Kidney biopsy is the gold standard for diagnosing DN;however,its invasive character is its primary limitation.The machine learning approach provides a non-invasive and specific criterion for diagnosing DN,although traditional machine learning algorithms need to be improved to enhance diagnostic performance.Methods:We applied high-throughput RNA sequencing to obtain the genes related to DN tubular tissues and normal tubular tissues of mice.Then machine learning algorithms,random forest,LASSO logistic regression,and principal component analysis were used to identify key genes(CES1G,CYP4A14,NDUFA4,ABCC4,ACE).Then,the genetic algorithm-optimized backpropagation neural network(GA-BPNN)was used to improve the DN diagnostic model.Results:The AUC value of the GA-BPNN model in the training dataset was 0.83,and the AUC value of the model in the validation dataset was 0.81,while the AUC values of the SVM model in the training dataset and external validation dataset were 0.756 and 0.650,respectively.Thus,this GA-BPNN gave better values than the traditional SVM model.This diagnosis model may aim for personalized diagnosis and treatment of patients with DN.Immunohistochemical staining further confirmed that the tissue and cell expression of NADH dehydrogenase(ubiquinone)1 alpha subcomplex,4-like 2(NDUFA4L2)in tubular tissue in DN mice were decreased.Conclusion:The GA-BPNN model has better accuracy than the traditional SVM model and may provide an effective tool for diagnosing DN. | WEI LIANG ZONGWEI ZHANG KEJU YANG HONGTU HU QIANG LUO ANKANG YANG LI CHANG YUANYUAN ZENG | 2023 | BIOCELL2023，47，6： | 0 |
| 17 | Understanding of the activity difference between nanogold and bulk gold by relativistic effects显示文摘It is a challenge to thoroughly understand the astonishing difference in catalytic activity between nanogold and bulk gold for some oxidation reactions. In this work,the Au–O interactions in various surroundings were investigated by DFT calculations and compared with the Ag–O interactions. We have found the three points.First,only Au–O bond can be significantly strengthened by the linear O–Au–O structure. Second,the Au–O bond is always stronger than the Ag–O bond when the bonds are embedded in common surroundings. Third,the Au–O bond becomes weaker than the Ag–O bond when the number of neighboring Au atoms becomes large,because the Au–O interactions are suppressed by the presence of neighboring gold atoms. The origin of these three points can be attributed to wider spatial extension of d orbitals of gold,induced by strong relativistic effects. The strong relativistic effects make nanogold with smaller coordinate numbers highly active due to the ease in forming strong Au–O bonds,especially for the O–Au–O bond,whereas gold atoms in bulk with larger coordination numbers chemically inert due to the strong suppression by neighboring gold atoms destabilizing the O–Au–O bond. | Keju Sun Masanori Kohyama Shingo Tanaka Seiji Takeda | 2015 | Journal of Energy Chemistry2015，24，4： | 0 |
| 18 | Sum-rate maximization for UAV-enabled two-way relay systems显示文摘In this paper,an Unmanned Aerial Vehicle(UAV)-enabled two-way relay system with Physical-layer Network Coding(PNC)protocol is considered.A rotary-wing UAV is applied as a mobile relay to assist two ground terminals for information interaction.Our goal is to maximize the sum-rate of the two-way relay system subject to mobility constraints,propulsion power consumption constraints,and transmit power constraints.The formulated problem is not easy to solve directly because it is a mixed integer non-convex optimization problem.Therefore,we decompose it into three sub-problems,and use the mutation arithmetic of the Genetic Algorithm(GA)and Successive Convex Approximation(SCA)to dispose.Besides,a high-efficiency iterative algorithm is proposed to obtain a locally optimal solution by jointly optimizing the time slot pairing,the transmit power allocation,and the UAV trajectory design.Numerical results demonstrate that the proposed design achieves significant gains over the benchmark designs. | Keju Lu Fahui Wu Lin Xiao Yipeng Liang Dingcheng Yang | 2022 | Digital Communications and Networks2022，8，6： | 0 |
| 19 | A simple construction of CRT-based ideal secret sharing scheme and its security extension based on common factor显示文摘Secret sharing(SS)is part of the essential techniques in cryptography but still faces many challenges in efficiency and security.Currently,SS schemes based on the Chinese Remainder Theorem(CRT)are either low in the information rate or complicated in construction.To solve the above problems,1)a simple construction of an ideal(t,n)-SS scheme is proposed based on CRT for a polynomial ring.Compared with Ning’s scheme,it is much more efficient in generating n pairwise coprime modular polynomials during the scheme construction phase.Moreover,Shamir’s scheme is also a special case of our scheme.To further improve the security,2)a common-factor-based(t,n)-SS scheme is proposed in which all shareholders share a common polynomial factor.It enables both the verification of received shares and the establishment of a secure channel among shareholders during the reconstruction phase.As a result,the scheme is resistant to eavesdropping and modification attacks by outside adversaries. | Lei WU Fuyou MIAO Keju MENG Xu WANG | 2022 | Frontiers of Computer Science2022，16，1： | 0 |
| 20 | Effective metal mold method for the production of bionic adhesives based on electrochemical modifications显示文摘Bionic adhesives with tip-expanded microstructural arrays have attracted considerable interest owing to their high adhesive performance at low preloads.Their mainstream manufacturing method is molding.Due to most molds are made of silicon or silicon-based soft templates,and have poor wear resistant or vulnerability to high temperature,limiting their use in large-scale manufacturing.Nickel is widely used as an embossing mold in the micro/nano-imprint industrial process owing to its good mechanical properties.However,the processing of metal molds for the fabrication of tip-expanded microstructural arrays is extremely challenging.In this study,using electrodeposition techniques,the shape of the micropores is modified to obtain end-controlled pores.The effect of the non-uniformity of the electric field on the microporous morphology in the electrodeposition process is systematically investigated.Furthermore,the mechanism of non-uniformity evolution of the microporous morphology is revealed.The optimized microporous metal array is used as a mold to investigate the cavity evolution laws of the elastic cushions under pre-load during the manufacturing process.As a result,typical bionic adhesives with tip-expansion are obtained.Moreover,corresponding adhesion mechanics are analyzed.The results show that electrochemical modifications have broad application prospects in the fabrication of tip-expanded microstructures,providing a new method for the large-scale fabrication of bionic adhesives based on metal molds. | Cong YUAN Keju JI Yiqiang TANG Zizhuo WANG Enhua CUI Jian CHEN Zhendong DAI | 2021 | Chinese Journal of Aeronautics2021，34，4： | 0 |
