1Thermal reliability analysis and optimization of polymer insulating through-silicon-vias(TSVs) for 3D integration显示文摘Polymer insulating through-silicon-vias(TSVs)is an attractive approach for high-performance 3D integration systems.To further demonstrate the polymer insulating TSVs,this paper investigates the thermal stability by measuring the leakage current under bias-temperature condition,studies the thermal stress characteristics with Finite Element Analysis(FEA),and tries to improve the thermal mechanical reliability of high-density TSVs array by optimizing the geometry parameters of pitch,liner and redistribution layer(RDL).The electrical measurements show the polymer insulating TSVs can maintain good insulation capability(less than 2 10 11A)under challenging bias-temperature conditions of 20 V and 200 C,despite the leakage degradation observation.The FEA results show that the thermal stress is significantly reduced at the sidewall,but highly concentrates at the surface,which is the potential location of mechanical failure.And,the analysis results indicate that the polymer insulating TSVs(diameter of 10 m,depth of 50 m)array with a pitch of 20 m,liner thickness of 1 m and RDL radius of 9m has an optimized thermal-mechanical reliability for application.ZHONG ShunAn WANG ShiWei CHEN QianWen DING YingTao 2014Science China(Technological Sciences)2014,57,1:5
2The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients显示文摘Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients. A total of 1,291 type 1 diabetic patients were enrolled in this study. Demographic information was collected. Laboratory tests including mixed-meal tolerance test, human leukocyte antigen alleles, hemoglobin A1 c, lipids, thyroid function and islet autoantibodies were conducted. The frequency of islet-specific autoantibody in newly diagnosed T1 DM patients(duration shorter than half year) was 73% in East China. According to binary logistic regressions, autoantibody positivity, longer duration and lower Body Mass Index were the risk factors of islet failure. As the disease developed, autoantibodies against glutamic acid decarboxylase declined as well as the other two autoantibodies against zinc transporter 8 and islet antigen 2. The decrease of autoantibodies was positively correlated with aggressive beta cell destruction. Autoantibodies can facilitate the identification of classic T1 DM from other subtypes and predict the progression of islet failure. As there were obvious heterogeneity in autoantibodies and clinical manifestation in different phenotypes of the disease, we should take more factors into consideration when identifying type 1 diabetes mellitus.Jin Liu Lingling Bian Li Ji Yang Chen Heng Chen Yong Gu Bingqin Ma Wei Gu Xinyu Xu Yun Shi Jian Wang Dalong Zhu Zilin Sun Jianhua Ma Hui Jin Xing Shi Heng Miao Bing Xin Yan Zhu Zhenwen Zhang Ruifang Bu Lan Xu Guangde Shi Wei Tang Wei Li Dongmei Zhou Jun Liang Xingbo Cheng Bimin Shi Jixiang Dong Ji Hu Chen Fang Shao Zhong Weinan Yu Weiping Lu Chenguang Wu Li Qian Jiancheng Yu Jialin Gao Xiaoqiang Fei Qingqing Zhang Xueqin Wang Shiwei Cui Jinluo Cheng Ning Xu Guofeng Wang Guoqing Han Chunrong Xu Yun Xie Minmin An Wei Zhang Zhixiao Wang Yun Cai Qi Fu Yu Fu Shuai Zheng Fan Yang Qingfang Hu Hao Dai Yu Jin Zheng Zhang Kuanfeng Xu Yifan Li Jie Shen Hongwen Zhou Wei He Xuqin Zheng Xiao Han Liping Yu Jinxiong She Mei Zhang Tao Yang 2016Science China(Life Sciences)2016,59,9:5

4Abiotic stress treatment reveals expansin like A gene OfEXLA1 improving salt and drought tolerance of Osmanthus fragrans by responding to abscisic acid显示文摘Sweet osmanthus(Osmanthus fragrans) is a having general approval aromatic tree in China that is widely applied to landscaping and gardening. However, the evergreen tree adaptability is limited by many environmental stresses. Currently, limited information is available regarding the genetic analysis and functional identification of expansin genes in response to abiotic stress in sweet osmanthus. In this study, a total of 29 expansin genes were identified and divided into four groups by genome-wide analysis from the sweet osmanthus genome. Transcriptome and quantitative Real-time PCR analysis showed that the cell wall-localized protein expansin-like A(OfEXLA1) gene was significantly induced by salt and drought treatment. Histochemical GUS staining of transgenic Arabidopsis lines in which GUS activity was driven with the OfEXLA1 promoter, GUS activity was significantly induced by salt, drought, and exogenous abscisic acid(ABA). In yeast, we found OfEXLA1overexpression significantly improved the population of cells compared with wild-type strains after NaCl and polyethylene glycol(PEG)treatment. Additionally, OfEXLA1 overexpression not only promoted plant growth, but also improved the salt and drought tolerance in Arabidopsis. To gain insight into the role of ABA signaling in the regulation of OfEXLA1 improving abiotic tolerance in sweet osmanthus, four differentially expressed ABA Insensitive 5(ABI5)-like genes(OfABL4, OfABL5, OfABL7, and OfABL8) were identified from transcriptome, and dualluciferase(dual-LUC) and yeast one hybrid(Y1H) assay showed that OfABL4 and OfABL5 might bind to OfEXLA1 promoter to accumulate the OfEXLA1 expression by responding to ABA signaling to improve abiotic tolerance in sweet osmanthus. These results provide the information for understanding the molecular functions of expansin-like A gene and molecular breeding of sweet osmanthus in future.Bin Dong Qianqian Wang Dan Zhou Yiguang Wang Yunfeng Miao Shiwei Zhong Qiu Fang Liyuan Yang Zhen Xiao Hongbo Zhao 2024Horticultural Plant Journal2024,10,2:0
5Sex ratio, floral traits, and genetic variation of androdioecious Osmanthus fragrans L. (Oleaceae) and the implications for maintenance of high male frequency显示文摘Several examples of androdioecy appear to have evolved from dioecy and have low male frequency(<0.5).However,the evolutionary pathway to androdioecy in Oleaceae may come from hermaphroditism.Osmanthus fragrans L.has a 1:1 sex ratio in nature populations.Significant differences are observed not only in flowering phenology but also in some floral traits between males and hermaphrodites.The protandry in the same population and the protogyny in the same plant may promote the xenogamy between genders.The majority of flower traits related with the pollen production are different between males and hermaphrodites.Males bear more flowering nodes,and more flowers per node,and larger anther in all three populations.This characteristic demonstrated that males have more male advantage than hermaphrodites.Population genetic structure of O.fragrans is genetically homogeneous at the species level,and most variations exist within a population.The percentage of variation among populations(13%)and between males and hermaphrodites(0%)is low.Moreover,genetic differentiation was very low between genders not only among populations but also in the same population.This genetic variation could be attributed to the occurrence of high levels of xenogamy between genders.Therefore,high male frequency and more male fitness advantage in males are the essential conditions for this mating system,which plays an important role during population reproduction and regeneration.The 1:1 sex ratio could be the result of integrative effects of sexual system,mating system,and reproductive success.Lihua Zhou Liyuan Yang Qiu Fang Bin Dong Yiguang Wang Shiwei Zhong Zheng Xiao Hongbo Zhao 2022Ornamental Plant Research2022,2,1:0
6Optimized Implementation for Wave Digital Filter Based Circuit Emulation on FPGA显示文摘A binary tree representation is designed in this paper for optimization of wave digital filter(WDF)implementation.To achieve this,an equivalent WDF model of the original circuit is converted into abinary tree representation at first.This WDF binary tree can then be transformed to several topologies with the same implication,since the WDF adaptors have a symmetrical behavior on their ports.Because the WDF implementation is related to field programmable gate array(FPGA)resource usage and the cycle time of emulation,choosing aproper binary tree topology for WDF implementation can help balance the complexity and performance quality of an emulation system.Both WDF-FPGA emulation and HSpice simulation on the same circuit are tested.There is no significant difference between these two simulations.However,in terms of time consumption,the WDF-FPGA emulation has an advantage over the other.Our experiment also demonstrates that the optimized WDF-FPGA emulation has an acceptable accuracy and feasibility.Yue Ma Shun'an Zhong Shiwei Ren 2017Journal of Beijing Institute of Technology2017,26,2:0
7LDL receptor-related protein 1 (LRP1),a novel target for opening the blood-labyrinth barrier(BLB)显示文摘Inner ear disorders are a cluster of diseases that cause hearing loss in more than 1.5 billion people worldwide.However,the presence of the blood-labyrinth barrier(BLB)on the surface of the inner ear capillaries greatly hinders the effectiveness of systemic drugs for prevention and intervention due to the low permeability,which restricts the entry of most drug compounds from the bloodstream into the inner ear tissue.Here,we report the finding of a novel receptor,low-density lipoprotein receptor-related protein 1(LRP1),that is expressed on the BLB,as a potential target for shuttling therapeutics across this barrier.As a proof-ofconcept,we developed an LRP1-binding peptide,IETP2,and covalently conjugated a series of model small-molecule compounds to it,including potential drugs and imaging agents.All compounds were successfully delivered into the inner ear and inner ear lymph,indicating that targeting the receptor LRP1 is a promising strategy to enhance the permeability of the BLB.The discovery of the receptor LRP1 will illuminate developing strategies for crossing the BLB and for improving systemic drug delivery for inner ear disorders.Xi Shi Zihao Wang Wei Ren Long Chen Cong Xu Menghua Li Shiyong Fan Yuru Xu Mengbing Chen Fanjun Zheng Wenyuan Zhang Xinbo Zhou Yue Zhang Shiwei Qiu Liyuan Wu Peng Zhou Xinze Lv Tianyu Cui Yuehua Qiao Hui Zhao Weiwei Guo Wei Chen Song Li Wu Zhong Jian Lin Shiming Yang 2022Signal Transduction and Targeted Therapy2022,7,7:0
8Survival outcomes of conversion surgery for metastatic pancreatic ductal adenocarcinoma after neoadjuvant therapy显示文摘Objective:To evaluate the survival outcomes of patients who underwent conversion surgery for metastatic pancreatic ductal adenocarcinoma(mPDAC)after neoadjuvant therapy(NAT)and to identify potential candidates that may benefit from this treat-ment strategy.Background:The role and eligibility population of conversion surgery for mPDAC remains controversial in the era of NAT.Methods:A consecutive cohort of patients diagnosed with mPDAC and treated with NAT followed by conversion surgery be-tween 2019 and 2021 were confirmed from a prospective database maintained by the Department of Pancreatic Hepatobiliary Surgery of Changhai Hospital.In accordance with residual metastases and technical resectability after NAT,patients were classi-fied as the complete pathological response of metastases(ypM0)resection group,residual metastases(ypM1)resection group,and exploration group.Median overall survival(mOS)was calculated using the Kaplan-Meier method,uni-and multivariable cox regression was performed to identify clinicopathological predictors of OS.Results:A total of 244 patients with mPDAC were identified from the prospective database,with 19(7.8%)patients who un-derwent ypM0 resection,22(9.0%)underwent ypM1 resection,and 23(9.4%)underwent explorative laparotomy.The mOS was 32.6 months for ypM0 resected patients,15.1 months for ypM1 resected patients,and 13.4 months for those who underwent explorative laparotomy(P<.001).Univariable and multivariable Cox regression analyses confirmed that ypM0 resection,normal-ization of preoperative CA19-9 levels,and continued adjuvant therapy were independent prognostic factors of conversion surgery for mPDAC after NAT.Subgroup analyses revealed that oligometastases and continued adjuvant therapy were associated with improved prognosis in the ypM1 resection group.Conclusion:In patients with mPDAC who underwent NAT followed by conversion surgery,the complete pathological response of metastases,normalization of preoperative CA19-9 levels,and continued adjuvant therapy were independent risk factors for prognosis.Patients with residual oligometastases after treatment were expected to prolong survival through resection.These patients may benefit from conversion surgery and should be potential candidates for this treatment strategy.Lingyu Zhu Suizhi Gao Xinqian Wu Bo Li Xiaohan Shi Xiaoyi Yin Huan Wang Meilong Shi Penghao Li Yikai Li Chaoliang Zhong Chuanqi Teng Jiawei Han Yiwei Ren Jian Wang Zhendong Fua Xinyu Liu Kailian Zheng Shiwei Guo Gang Jin 2023Journal of Pancreatology2023,6,3:0
92D Augmented Coprime Array Geometry Based on the Difference and Sum Coarray Concept显示文摘The concept of difference and sum(diff-sum)coarray has attracted a lot of attentions in the estimation of direction-of-arrival(DOA)for the past few years,due to its high degrees-of-freedom(DOFs).A vectorized conjugate augmented MUSIC(VCA-MUSIC)algorithm is applied to generate an equivalent signal model which contains the virtual sensor positions of both the difference and sum of the physical sensors in the two-dimensional(2D)arrays,by utilizing both the spatial and temporal information.Besides,an augmented 2D coprime array configuration is presented with the basis on the concept of difference and sum coarray.By compressing the inter-element spacing of one subarray and introducing the proper separation between the two subarrays of 2D coprime array,the redundancy between the difference coarray and the sum one can be reduced so that more virtual sensors in both coarrays can make contributions to the DOFs.As a result,a much larger consecutive area in the diff-sum coarray can be achieved,which can significantly increase the DOFs.Numerical simulations verify the superiority of the proposed array configuration.Guiyu Wang Shun’an Zhong Xiangnan Li Xiaohua Wang Shiwei Ren 2020Journal of Beijing Institute of Technology2020,29,2:0
10The SlTPL3–SlWUS module regulates multi-locule formation in tomato by modulating auxin and gibberellin levels in the shoot apical meristem显示文摘Malformed fruits depreciate a plant’s market value.In tomato(Solanum lycopersicum),fruit malformation is associated with the multi-locule trait,which involves genes regulating shoot apical meristem(SAM)development.The expression pattern of TOPLESS3(SITPL3)throughout SAM development prompted us to investigate its functional significance via RNA interference(RNAi)and clustered regularly interspaced short palindromic repeats/CRISPR-associated nuclease 9(Cas9)-mediated gene editing.Lower SITPL3 transcript levels resulted in larger fruits with more locules and larger SAMs at the 5 d after germination(DAG5)stage.Differentially expressed genes in the SAM of wild-type(WT)and SITPL3-RNAi plants,identified by transcriptome deep sequencing(RNA-seq),were enriched in the gibberellin(GA)biosynthesis and plant hormone signaling pathways.Moreover,exogenous auxin and paclobutrazol treatments rescued the multi-locule phenotype,indicating that SITPL3 affects SAM size by mediating auxin and GA levels in the SAM.Furthermore,SITPL3 interacted with WUSCHEL(SIWUS),which plays an important role in SAM size maintenance.We conducted RNA-seq and DNA affinity purification followed by sequencing(DAP-seq)analyses to identify the genes regulated by SITPL3 and SIWUS in the SAM and to determine how they regulate SAM size.We detected24 overlapping genes regulated by SITPL3 and SIWUS and harboring an SIWUS-binding motif in their promoters.Furthermore,functional annotation revealed a notable enrichment for functions in auxin transport,auxin signal transduction,and GA biosynthesis.Dual-luciferase assays also revealed that SITPL3 enhances SIWUS-mediated regulation(repression and activation)of SIPIN3 and SIGA2 ox4 transcription,indicating that the SITPL3-SIWUS module regulates SAM size by mediating auxin distribution and GA levels,and perturbations of this module result in enlarged SAM.These results provide novel insights into the molecular mechanism of SAM maintenance and locule formation in tomato and highlight the SITPL3-SIWUS module as a key regulator.Shiwei Song Binbin Huang Zanlin Pan Qiuxiang Zhong Yinghua Yang Da Chen Lisha Zhu Guojian Hu Mi He Caiyu Wu Mohammed Zouine Riyuan Chen Mondher Bouzayen Yanwei Hao 2022Journal of Integrative Plant Biology2022,64,11:0
