| 1 | Rice MtN3/saliva/SWEET gene family: Evolution,expression profiling, and sugar transport显示文摘The rice MtN3/saliva/SWEET gene family consists of21 paralogs. However, their functions in physiological processes are largely unknown, although at least three of the 21 paralogs are used by pathogenic bacteria to infect rice.Here, we report the evolutionary features, transcriptional characteristics, and putative functions in sugar transport of this gene family. The wild rice accessions in this study included those with AA, BB, CC, BBCC, CCDD, EE, and GG genomes,which appeared approximately 0.58–14.6 million years ago.The structures, chromosomal locations, phylogenetic relationships, and homologous distribution among the accessions suggest that the number of rice MtN3/saliva/SWEET paralogs gradually increased as the Oryza genus evolved, and one third of the paralogs may have originated recently. These paralogs are differentially expressed in vegetative and reproductive tissues, in the leaf senescence process, and in signaling dependent on gibberellic acid, cytokinin, or 1-naphthalene acetic acid(an analog of auxin), suggesting that they may be associated with multiple physiological processes. Four paral ogs could transport galactose in yeast, which suggests tha they may have a similar function in rice. These results will help to elucidate their roles and biochemical functions in rice development, adaptation to environment, host-pathogen interaction, and so forth. | Meng Yuan Junwei Zhao Renyan Huang Xianghua Li Jinghua Xiao Shiping Wang | 2014 | Journal of Integrative Plant Biology2014，56，6： | 14 |

| 3 | An efficient VLSI architecture of speeded-up robust feature extraction for high resolution and high frame rate video显示文摘This paper proposes a VLSI architecture of the optimized Speeded-Up Robust Feature (SURF) algorithm. The SURF algorithm which is widely used in computer vision applications, locates interest points (IPoints) and extracts feature descriptors based on the surrounding gradients. In the proposed approach, the SURF algorithm is modified to make it more suitable for hardware implementation with little accuracy lost compared to OpenSURF, an open source software implementation based on OpenCV. The resource cost and throughput gain are balanced. Word Length Reduction (WLR) is adopted to compress the integral image and reduce the occupied memory resources. The orientations and the feature descriptors of the IPoints are calculated in a more efficient way, which significantly reduces memory accesses. Moreover, the operations are pipelined both in and among the proposed hardware modules. This VLSI architecture has been validated on FPGA (Xilinx Virtex-4 XC4VLX80), which is able to detect IPoints and extract SURF feature descriptors in a VGA (640 × 480) 64 fps video input with a 96 MHz working frequency while dissipating 1.278 W. This throughput is more than double of the ones reported in the latest literatures. | ZHANG WeiLong LIU LeiBo YIN ShouYi ZHOU RenYan CAI ShanShan WEI ShaoJun | 2013 | Science China(Information Sciences)2013，56，7： | 6 |
| 4 | Model for Failure Point Process of a Repairable System and Application显示文摘A engineering system is usually repairable,and failure process of a repairable system is often described by a failure point process. The power law model is a commonly used approach to model the failure point process.This paper introduces the concept and model for the failure process of repairable system. The method of parameter estimation is developed,and failure observations are fitted into a power-law model by using the least square method. Two applications of the pressent model are discussed according to the practical failure data of the central cooling system of a nuclear power plant. One application is determining the optimal overhaul time,and the other is evaluating the quality of maintenance. This paper provides references for the overhaul decision making and maintenance quality evaluation in reality. | JIANG Renyan CHEN Hao | 2018 | International Journal of Plant Engineering and Management2018，23，2： | 1 |

| 6 | Anisotropic in-plane thermal conductivity for multi-layer WTe_(2)显示文摘Improving thermal transport between substrate and transistors has become a vital solution to the thermal challenge in nanoelectronics.Recently 2D WTe_(2) has sparked extensive interest because of heavy atomic mass and low Debye temperature.Here,the thermal transport of supported WTe_(2) was studied via Raman thermometry with electrical heating.The supported 30 nm WTe2 encased with 70 nm Al_(2)O_(3) delivered 4.8 W·m^(-1)·K^(-1)in-plane thermal conductivity along zigzag direction at room temperature,which was almost 1.6 times larger than that along armchair direction(3.0 W·m^(-1)·K^(-1)).Interestingly,the superior and inferior directions for thermal transport are just opposite of those for electrical transport.Hence,a heat manipulation model in WTe_(2) FET device was proposed.Within the designed configuration,waste heat in WTe_(2) would be mostly dissipated to metal contacts located along zigzag,relieving the local temperature discrepancy in the channel effectively and preventing degradation or breakdown.Our study provides new insight into thermal transport of anisotropic 2D materials,which might inspire energy-efficient nanodevices in the future. | Yuehua Wei Chuyun Deng Xiaoming Zheng Yangbo Chen Xiangzhe Zhang Wei Luo Yi Zhang Gang Peng Jinxin Liu Han Huang Weiwei Cai Qi Ge Renyan Zhang Xueao Zhang Shiqiao Qin | 2022 | Nano Research2022，15，1： | 1 |

| 8 | Enhancement of MoTe2 near-infrared absorption with gold hollow nanorods for photodetection显示文摘Infrared(IR)light photodetection based on two dimensional(2D)materials of proper bandgap has attracted increasing attention.However,the weak IR absorption in 2D materials,due to their ultrathin attribute and indirect bandgap in multilayer structures,degrades their performance when used as IR photodetectors.In this work,we utilize the fact that few-layer MoTe2 flake has a near-IR(NIR)bandgap and demonstrate a^60-fold enhancement of NIR response by introducing a gold hollow nanorods on the surface.Such gold hollow nanorods have distinct absorption peak located also at the NIR regime,therefore induces strong resonance,benefitting NIR absorption in MoTe2,resulting in strong near-field enhancement.With the evidence from steady and transient state optical spectra,we confirm that the enhancement of NIR response originates only photon absorption,rather than electron transport at interfaces as observed in other heterostructures,therefore,precluding the requirement of high-quality interfaces for commercial applications. | Jiawen You Ye Yu Kai Cai Dongming Zhou Haiming Zhu Renyan Wang Qingfu Zhang Hongwei Liu Yuting Cai Dong Lu Jang-Kyo Kim Lin Gan Tianyou Zhai Zhengtang Luo | 2020 | Nano Research2020，13，6： | 1 |

| 12 | Optimization of speeded-up robust feature algorithm for hardware implementation显示文摘Speeded-Up Robust Feature(SURF)is a widely-used robust local gradient feature detection and description algorithm.The algorithm itself can be implemented easily on general-purpose processors.However,the software implementation of SURF cannot achieve a performance high enough to meet the practical real-time requirements.And what is more,the huge data storage and the floating point operation of SURF algorithm make it hard and onerous to design and verify corresponding hardware implementation.This paper customized a SURF algorithm for hardware implementation,which combined several optimization methods in previous literature and three approaches(named Word Length Reduction(WLR),Low Bits Abandon(LBA),and Sampling Radius Reduction(SRR)).The computation operations of the simplified and optimized SURF(P-SURF)were reduced by 50%compared with the original SURF.At the same time,the Recall and Precision of the SURF feature descriptor are only dropped by 0.31 on average in the typical testing set,which are within an acceptable accuracy range.P-SURF has been implemented on hardware using TSMC 65 nm process,and the architecture of the whole system mainly contains four modules,including Integral Image Generator,IPoint Detector,IPoint Orientation Assigner,and IPoint Feature Vector Extractor.The chip size is 3.4×4 mm2.The power usage is less than 220mW according to the Synopsys Prime time while extracting IPoints in a video input of VGA(640×480)172 fps operating at 200 MHz.The performance is better than the results reported in literature. | CAI ShanShan LIU LeiBo YIN ShouYi ZHOU RenYan ZHANG WeiLong WEI ShaoJun | 2014 | Science China(Information Sciences)2014，57，4： | 1 |

| 17 | Microglial NLRP3 inflammasome-mediated neuroinflammation and therapeutic strategies in depression显示文摘Previous studies have demonstrated a bidirectional relationship between inflammation and depression.Activation of the nucleotide-binding oligomerization domain,leucine-rich repeat,and NLR family pyrin domain-containing 3(NLRP3)inflammasomes is closely related to the pathogenesis of various neurological diseases.In patients with major depressive disorder,NLRP3 inflammasome levels are significantly elevated.Understanding the role that NLRP3 inflammasome-mediated neuroinflammation plays in the pathogenesis of depression may be beneficial for future therapeutic strategies.In this review,we aimed to elucidate the mechanisms that lead to the activation of the NLRP3 inflammasome in depression as well as to provide insight into therapeutic strategies that target the NLRP3 inflammasome.Moreover,we outlined various therapeutic strategies that target the NLRP3 inflammasome,including NLRP3 inflammatory pathway inhibitors,natural compounds,and other therapeutic compounds that have been shown to be effective in treating depression.Additionally,we summarized the application of NLRP3 inflammasome inhibitors in clinical trials related to depression.Currently,there is a scarcity of clinical trials dedicated to investigating the applications of NLRP3 inflammasome inhibitors in depression treatment.The modulation of NLRP3 inflammasomes in microglia holds promise for the management of depression.Further investigations are necessary to ascertain the efficacy and safety of these therapeutic approaches as potential novel antidepressant treatments. | Qiuqin Han Wenhui Li Peiqing Chen Lijuan Wang Xiwen Bao Renyan Huang Guobin Liu Xiaorong Chen | 2024 | Neural Regeneration Research2024，19，9： | 0 |
| 18 | Comparison of short-term toxicity of 14 common phycotoxins(alone and in combination)to the survival of brine shrimp Artemia salina显示文摘Toxic harmful algal blooms(HABs)can cause deleterious effects in marine organisms,threatening the stability of marine ecosystems.It is well known that different strains,natural populations and growth conditions of the same toxic algal species may lead to different amount of phycotoxin production and the ensuing toxicity.To fully assess the ecological risk of toxic HABs,it is of great importance to investigate the toxic effects of phycotoxins in marine organisms.In this study,the short-term toxicity of 14 common phycotoxins(alone and in combination)in the marine zooplankton Artemia salina was investigated.The 48 h LC_(50)of the 14 phycotoxins varied from 0.0193µg/mL to 2.415µg/mL.The most potent phycotoxin was azaspiracids-3(AZA3;with a LC_(50)of 0.0193µg/mL),followed by azaspiracids-2(AZA2;0.0226µg/mL),pectenotoxin-2(PTX2;0.0460µg/mL)and dinophysistoxin-1(DTX1;0.0818µg/mL).For the binary exposure,okadaic acid(OA)induced potential additive effects with DTX1,probably due to their similar structure(polyether fatty acid)and mode of action(attacking the serine/threonine phosphoprotein phosphatases).On the other hand,OA showed potential antagonistic effects with PTX2,which might be accounted for by their activation on the detoxification activity of cytochrome P450 activity.In addition,DTX1 induced potential synergetic effects with saxitoxin(STX),yessotoxin(YTX)or PTX2,suggesting the hazard potency of the mixtures of DTX1 and other phycotoxins(like STX,YTX and PTX2)with regard to the ecological risk.These results provide valuable toxicological data for assessing the impact of phycotoxins on marine planktonic species and highlight the potential ecological risk of toxic HABs in marine ecosystems. | Yuting Zhang Shanshan Song Bin Zhang Yang Zhang Miao Tian Ziyi Wu Huorong Chen Guangmao Ding Renyan Liu Jingli Mu | 2023 | Acta Oceanologica Sinica2023，42，2： | 0 |
| 19 | HIGH PRECISION CCD CALIBRATION AND ITS APPLICATIONS显示文摘With the help of CCD images,the realization of high precision po-sitioning and measurement has become the basic standard for machine vision andreal time photogrammetry systems.However,deformation and other sorts ofdegradation occurring during transmission are major limiting factors of the preci-sion attainable with most current CCD cameras and frame grabbers.So a preciseradiometric and geometric transmission of images from CCD sensor to memory is afundamental aspect of CCD camera calibration.The geometric calibration system,which uses some image processing algorithms of the CCD camera based on the re-searched and developed system is discussed.The reliability and validity are alsodiscussed.The experimental results for the calibration of the CCD array will betaken as an important quality index for CCD evaluation. | GE Renyan | 1998 | Geo-Spatial Information Science1998，1，1： | 0 |
| 20 | Modulation of the Anisotropic Electronic Properties in ReS_(2) via Ferroelectric Film显示文摘Anisotropic response in two-dimensional materials has emerged with attractive potential applications in angle-sensitive areas.However,the challenge with current studies on anisotropic response is due to the main use of the structural materials of pristine to examine the physical properties in different direc-tions,which cause restriction of the anisotropic ratio within a narrow range,thereby,limiting their practical applications. | Renyan Wang Fengya Zhou Liang Lv Shasha Zhou Yiwei Yu Fuwei Zhuge Huiqiao Li Lin Gan Tianyou Zhai | 2019 | CCS Chemistry2019，1，3： | 0 |
