2Satellite lithium-ion battery remaining useful life estimation with an iterative updated RVM fused with the KF algorithm显示文摘Lithium-ion batteries have become the third-generation space batteries and are widely utilized in a series of spacecraft.Remaining Useful Life(RUL) estimation is essential to a spacecraft as the battery is a critical part and determines the lifetime and reliability.The Relevance Vector Machine(RVM) is a data-driven algorithm used to estimate a battery's RUL due to its sparse feature and uncertainty management capability.Especially, some of the regressive cases indicate that the RVM can obtain a better short-term prediction performance rather than long-term prediction.As a nonlinear kernel learning algorithm, the coefficient matrix and relevance vectors are fixed once the RVM training is conducted.Moreover, the RVM can be simply influenced by the noise with the training data.Thus, this work proposes an iterative updated approach to improve the long-term prediction performance for a battery's RUL prediction.Firstly, when a new estimator is output by the RVM, the Kalman filter is applied to optimize this estimator with a physical degradation model.Then, this optimized estimator is added into the training set as an on-line sample, the RVM model is re-trained, and the coefficient matrix and relevance vectors can be dynamically adjusted to make next iterative prediction.Experimental results with a commercial battery test data set and a satellite battery data set both indicate that the proposed method can achieve a better performance for RUL estimation.Yuchen SONG Datong LIU Yandong HOU Jinxiang YU Yu PENG 2018Chinese Journal of Aeronautics2018,31,1:29
3Advances on strategies for searching for next generation thermal barrier coating materials显示文摘Thermal barrier coating(TBC) materials play important roles in gas turbine engines to protect the Nibased super-alloys from the high temperature airflow damage. High melting point, ultra-low thermal conductivity, large thermal expansion coefficient, excellent damage tolerance and moderate mechanical properties are the main requirements of promising TBC materials. In order to improve the efficiency of jet and/or gas turbine engines, which is the key of improved thrust-to-weight ratios and the energysaving, significant efforts have been made on searching for enhanced TBC materials. Theoretically, density functional theory has been successfully used in scanning the structure and properties of materials, and at the same time predicting the mechanical and thermal properties of promising TBC materials for high and ultrahigh temperature applications, which are validated by subsequent experiments. Experimentally,doping and/or alloying are also widely applied to further decrease their thermal conductivities. Now, the strategy through combining theoretical calculations and experiments on searching for next generation thermal insulator materials is widely adopted. In this review, the common used techniques and the recent advantages on searching for promising TBC materials in both theory and experiments are summarized.Bin Liu Yuchen Liu Changhua Zhu Huimin Xiang Hongfei Chen Luchao Sun Yanfeng Gao Yanchun Zhou 2019Journal of Materials Science & Technology2019,35,5:24
4Microvesicle-delivery miR-150 promotes tumorigenesis by up-regulating VEGF,and the neutralization of miR-150 attenuate tumor development显示文摘Tumor-associated macrophages(TAMs)mostly exhibit M2-like(alternatively activated)properties and play posi-tive roles in angiogenesis and tumorigenesis.Vascular en-dothelial growth factor(VEGF)is a key angiogenic factor.During tumor development,TAMs secrete VEGF and other factors to promote angiogenesis;thus,anti-treatment against TAMs and VEGF can repress cancer development,which has been demonstrated in clinical trials and on an experimental level.In the present work,we show that miR-150 is an oncomir because of its promotional effect on VEGF.MiR-150 targets TAMs to up-regulate their secre-tion of VEGF in vitro.With the utilization of cell-derived vesicles,named microvesicles(MVs),we transferred an-tisense RNA targeted to miR-150 into mice and found that the neutralization of miR-150 down-regulates miR-150 and VEGF levels in vivo and attenuates angiogenesis.There-fore,we proposed the therapeutic potential of neutralizing miR-150 to treat cancer and demonstrated a novel,natu-ral,microvesicle-based method for the transfer of nucleic acids.Yuchen Liu Luming Zhao Dameng Li Yuan Yin Chen-Yu Zhang Jing Li Yujing Zhang 2013Protein & Cell2013,4,12:18
5CapOX as neoadjuvant chemotherapy for locally advanced operable colon cancer patients: a prospective single-arm phase Ⅱ trial显示文摘Objective: The aim of this prospective, single-arm phase II trial was to confirm the safety and efficacy of neoadjuvant chemotherapy(NAC) using oxaliplatin plus capecitabine(Cap OX) for patients with operable locally advanced colon cancer(CC).Methods: Patients with computed tomography-defined T4 or lymph node-positive CCs were enrolled. After radiological staging, patients were treated with at least 2 cycles of NAC consisting of 130 mg/m2 oxaliplatin on d 1,plus 1,000 mg/m2 capecitabine twice daily for 14 d every 3 weeks, followed by surgery, and then with the rest cycles of adjuvant chemotherapy. Radiological response was evaluated after 2 cycles of NAC. Tumor response, treatment toxicity, and surgical complications were recorded. The pathological response to therapy was evaluated according to the tumor regression grade(TRG) score. The primary endpoint was pathologic tumor response. This trial is registered in Clinical Trials.gov(No: NCT02415829).Results: Forty-seven patients were enrolled in the study. Forty-two patients completed the planned treatments.The total radiological response rate was 68%(32/47), including complete and partial response rates of 2%(1/47)and 66%(31/47), respectively. Stable disease was observed in 32%(15/47) and progressive disease was observed in none. Complete pathologic response, major regression, and at least moderate regression were achieved in 1(2%), 2(4%), and 29(62%) patients, respectively. Four patients developed grade 3 treatment toxicities. One patient with wound infection occurred after operation(1/47, 2%). There was no treatment-related death.Conclusions: Our results suggest that NAC with Cap OX is an effective and safe treatment option for patients with locally advanced CCs.Fangqi Liu Li Yang Yuchen Wu Cong Li Jiang Zhao Adili Keranmu Hongtu Zheng Dan Huang Lei Wang Tong Tong Junyan Xu Ji Zhu Sanjun Cai Ye Xu 2016Chinese Journal of Cancer Research2016,28,6:14
6Role of pyroptosis in inflammation and cancer显示文摘Pyroptosis is a form of programmed cell death mediated by gasdermin and is a product of continuous cell expansion until the cytomembrane ruptures,resulting in the release of cellular contents that can activate strong inflammatory and immune responses.Pyroptosis,an innate immune response,can be triggered by the activation of inflammasomes by various influencing factors.Activation of these inflammasomes can induce the maturation of caspase-1 or caspase-4/5/11,both of which cleave gasdermin D to release its N-terminal domain,which can bind membrane lipids and perforate the cell membrane.Here,we review the latest advancements in research on the mechanisms of pyroptosis,newly discovered influencing factors,antitumoral properties,and applications in various diseases.Moreover,this review also provides updates on potential targeted therapies for inflammation and cancers,methods for clinical prevention,and finally challenges and future directions in the field.Xiang Wei Feng Xie Xiaoxue Zhou Yuchen Wu Haiyan Yan Ting Liu Jun Huang Fangwei Wang Fangfang Zhou Long Zhang 2022Cellular & Molecular Immunology2022,19,9:11
7Global Dynamic Molecular Profiling of Stomatal Lineage Cell Development by Single-Cell RNA Sequencing显示文摘The regulation of stomatal lineage cell development has been extensively investigated.However,a comprehensive characterization of this biological process based on single-cell transcriptome analysis has not yet been reported.In this study,we performed RNA sequencing on 12844 individual cells from the cotyledons of 5-day-old Arabidopsis seedlings.We identified 11 cell clusters corresponding mostly to cells at specific stomatal developmental stages using a series of marker genes.Comparative analysis of genes with the highest variable expression among these cell clusters revealed transcriptional networks that regulate development from meristemoid mother cells to guard mother cells.Examination of the developmental dynamics of marker genes via pseudo-time analysis revealed potential interactions between these genes.Collectively,our study opens the door for understanding how the identified novel marker genes participate in the regulation of stomatal lineage cell development.Zhixin Liu Yaping Zhou Jinggong Guo Jiaoai Li Zixia Tian Zhinan Zhu Jiajing Wang Rui Wu Bo Zhang Yongjian Hu Yijing Sun Yan Shangguan Weiqiang Li Tao Li Yunhe Hu Chenxi Guo Jean-David Rochaix Yuchen Miao Xuwu Sun 2020Molecular Plant2020,13,8:11
8Myeloid-specific targeting of Notch ameliorates murine renal fibrosis via reduced infiltration and activation of bone marrowderived macrophage显示文摘Macrophages play critical roles in renal fibrosis.However,macrophages exhibit ontogenic and functional heterogeneities,and which population of macrophages contributes to renal fibrosis and the underlying mechanisms remain unclear.In this study,we genetically targeted Notch signaling by disrupting the transcription factor recombination signal binding protein-JK(RBP-J),to reveal its role in regulation of macrophages during the unilateral ureteral obstruction(UUO)-induced murine renal fibrosis.Myeloid-specific disruption of RBP-J attenuated renal fibrosis with reduced extracellular matrix deposition and myofibroblast activation,as well as attenuated epithelial-mesenchymal transition,likely owing to the reduced expression of TGF-β.Mean while,RBP-J deletion significantly hampered macrophage infiltration and activation in fibrotic kidney,although their proliferation appeared unaltered.By using macrophage clearance experiment,we found that kidney resident macrophages made negligible contribution,but bone marrow(BM)-derived macrophages played a major role in renal fibrogenesis.Further mechanistic analyses showed that Notch blockade reduced monocyte emigration from BM by down-regulating CCR2 expression.Finally,we found that myeloid-specific Notch activation aggravated renal fibrosis,which was mediated by CCR2^+macrophages infiltration.In summary,our data have unveiled that myeloid-specific targeting of Notch could ameliorate renal fibrosis by regulating BM-derived macrophages recruitment and activation,providing a novel strategy for intervention of this disease.Yali Jiang Yuanyuan Wang Pengfei Ma Dongjie An Junlong Zhao Shiqian Liang Yuchen Ye Yingying Lu Peng Zhang Xiaowei Liu Hua Han Hongyan Qin 2019Protein & Cell2019,10,3:10
9Xa7, a new executor R gene that confers durable and broad-spectrum resistance to bacterial blight disease in rice显示文摘Bacterial blight(BB)is a globally devastating rice disease caused by Xanthomonas oryzae pv.oryzae(Xoo).The use of disease resistance(R)genes in rice breeding is an effective and economical strategy for the control of this disease.Nevertheless,a majority of R genes lack durable resistance for long-term use under global warming conditions.Here,we report the isolation of a novel executor R gene,Xa7,that confers extremely durable,broad-spectrum,and heat-tolerant resistance to Xoo.The expression of Xa7 was induced by incompatible Xoo strains that secreted the transcription activator-like effector(TALE)AvrXa7 or PthXo3,which recognized effector binding elements(EBEs)in the Xa7 promoter.Furthermore,Xa7 induction was faster and stronger under high temperatures.Overexpression of Xa7 or co-transformation of Xa7 with avrXa7 triggered a hypersensitive response in plants.Constitutive expression of Xa7 activated a defense response in the absence of Xoo but inhibited the growth of transgenic rice plants.In addition,analysis of over 3000 rice varieties showed that the Xa7 locuswas found primarily in the indica and aus subgroups.A variation consisting of an 11-bp insertion and a base substitution(G to T)was found in EBEAvrXa7 in the tested varieties,resulting in a loss of Xa7 BB resistance.Through a decade of effort,we have identified an important BB resistance gene and characterized its distinctive interaction with Xoo strains;these findings will greatly facilitate research on the molecular mechanism of Xa7-mediated resistance and promote the use of this valuable gene in breeding.Xifeng Chen Pengcheng Liu Le Mei Xiaoling He Long Chen Hui Liu Shurong Shen Zhandong Ji Xixi Zheng Yuchen Zhang Zhenyu Gao Dali Zeng Qian Qian Bojun Ma 2021Plant Communications2021,2,3:9
10Small non-coding RNAs transfer through mammalian placenta and directly regulate fetal gene expression显示文摘Jing Li Yujing Zhang Dameng Li Yuchen Liu Danping Chu Xiaohong Jiang Dongxia Hou Ke Zen Chen-Yu zhang 2015Protein & Cell2015,6,6:9
11Combination of anti-PD-1 antibody with P-GEMOX as a potentially effective immunochemotherapy for advanced natural killer/T cell lymphoma显示文摘Advanced natural killer/T cell lymphoma(NKTL)has demonstrated poor prognosis with currently available therapies.Here,we report the efficacy of anti-programmed death 1(PD-1)antibody with the P-GEMOX(pegaspargase,gemcitabine,and oxaliplatin)regimen in advanced NKTL.Nine patients underwent six 21-day cycles of anti-PD-1 antibody(day 1),pegaspargase 2000 U/m^(2)(day 1),gemcitabine 1 g/m^(2)(days 1 and 8)and oxaliplatin 130 mg/m^(2)(day 1),followed by anti-PD-1 antibody maintenance every 3 weeks.Programmed death-ligand 1(PD-L1)expression and genetic alterations were determined in paraffin-embedded pretreatment tissue samples using immunohistochemistry and next-generation sequencing(NGS)analysis.Responses were assessed using 18F-fluorodeoxyglucose positron emission tomography(18FDG-PET)and computed tomography or magnetic resonance imaging.Eight patients exhibited significant responses,comprising of seven complete remissions and one partial remission(overall response rate:88.9%).After a median follow-up of 10.6 months,6/9 patients(66.7%)remained in complete remission.The most common grade 3/4 adverse events were anemia(33.3%),neutropenia(33.3%),and thrombocytopenia(33.3%);all of which were manageable and resolved.Immunochemotherapy produced a high response rate in patients with positive PD-L1 expression(5/6,83.3%).NGS analysis suggested that STAT3/JAK3/PD-L1 alterations and ARID1A mutation were associated with immunochemotherapy efficacy.Mutation in DDX3X and alteration in epigenetic modifiers of KMT2D,TET2,and BCORL1 might indicate a poor response to immunochemotherapy.In conclusion,the anti-PD-1 antibody plus P-GEMOX regimen demonstrated promising efficacy in advanced NKTL.PD-L1 expression combined with specific genetic alterations could be used as potential biomarkers to predict therapeutic responses to immunochemotherapy.Jun Cai Panpan Liu Huiqiang Huang Yajun Li Shuyun Ma Hui Zhou Xiaopeng Tian Yuchen Zhang Yan Gao Yi Xia Xuanye Zhang Hang Yang Lirong Li Qingqing Cai 2020Signal Transduction and Targeted Therapy2020,5,1:6
12Optimizing the CRISPR/Cas9 system for genome editing in grape by using grape promoters显示文摘The efficacy of the CRISPR/Cas9 system in grapevine(Vitis vinifera L.)has been documented,but the optimization of this system,as well as CRISPR/Cas9-mediated multiplex genome editing,has not been explored in this species.Herein,we identified four VvU3 and VvU6 promoters and two ubiquitin(UBQ)promoters in grapevine and demonstrated that the use of the identified VvU3/U6 and UBQ2 promoters could significantly increase the editing efficiency in grape by improving the expression of sgRNA and Cas9,respectively.Furthermore,we conducted multiplex genome editing using the optimized CRISPR/Cas9 vector that contained the conventional multiple sgRNA expression cassettes or the polycistronic tRNA-sgRNA cassette(PTG)by targeting the sugar-related tonoplastic monosaccharide transporter(TMT)family members TMT1 and TMT2,and the overall editing efficiencies were higher than 10%.The simultaneous editing of TMT1 and TMT2 resulted in reduced sugar levels,which indicated the role of these two genes in sugar accumulation in grapes.Moreover,the activities of the VvU3,VvU6,and UBQ2 promoters in tobacco genome editing were demonstrated by editing the phytoene desaturase(PDS)gene in Nicotiana benthamiana leaves.Our study provides materials for the optimization of the CRISPR/Cas9 system.To our knowledge,our simultaneous editing of the grape TMT family genes TMT1 and TMT2 constitutes the first example of multiplex genome editing in grape.The multiplex editing systems described in this manuscript expand the toolbox of grape genome editing,which would facilitate basic research and molecular breeding in grapevine.Chong Ren Yanfei Liu Yuchen Guo Wei Duan Peige Fan Shaohua Li Zhenchang Liang 2021Horticulture Research2021,8,1:6
13Vertical Distribution Characteristics of PM2.5 Observed by a Mobile Vehicle Lidar in Tianjin, China in 2016显示文摘We present mobile vehicle lidar observations in Tianjin, China during the spring, summer, and winter of 2016. Mobile observations were carried out along the city border road of Tianjin to obtain the vertical distribution characteristics of PM_(2.5). Hygroscopic growth was not considered since relative humidity was less than 60% during the observation experiments. PM_(2.5) profile was obtained with the linear regression equation between the particle extinction coefficient and PM_(2.5) mass concentration. In spring, the vertical distribution of PM_(2.5) exhibited a hierarchical structure. In addition to a layer of particles that gathered near the ground, a portion of particles floated at 0.6–2.5-km height. In summer and winter, the fine particles basically gathered below 1 km near the ground. In spring and summer, the concentration of fine particles in the south was higher than that in the north because of the influence of south wind. In winter, the distribution of fine particles was opposite to that measured during spring and summer. High concentrations of PM_(2.5) were observed in the rural areas of North Tianjin with a maximum of 350 μg m–3 on 13 December2016. It is shown that industrial and ship emissions in spring and summer and coal combustion in winter were the major sources of fine particles that polluted Tianjin. The results provide insights into the mechanisms of haze formation and the effects of meteorological conditions during haze–fog pollution episodes in the Tianjin area.Lihui LYU Yunsheng DONG Tianshu ZHANG Cheng LIU Wenqing LIU Zhouqing XIE Yan XIANG Yi ZHANG Zhenyi CHEN Guangqiang FAN Leibo ZHANG Yang LIU Yuchen SHI Xiaowen SHU 2018Journal of Meteorological Research2018,32,1:5
14Functional analysis of a novel C-glycosyltransferase in the orchid Dendrobium catenatum显示文摘Flavonoids,which are a diverse class of phytonutrients,are used by organisms to respond to nearly all abiotic stresses and are beneficial for human health.Glycosyltransferase,used during the last step of flavonoid biosynthesis,is important in flavonoid enrichment.However,little is known about glycosyltransferase in the orchid Dendrobium catenatum(D.officinale).In this study,we isolated a novel C-glycosyltransferase(designated DcaCGT)from the orchid D.catenatum by identifying and analyzing 82 putative genes in the GT1 family.DcaCGT could specifically catalyze not only di-C-glycosylation but also O-glycosylation.Apart from the normal function of catalyzing 2-hydroxynaringenin and phloretin to the respective di-C-glycosides,DcaCGT also catalyzes apigenin to cosmosiin.Targeted metabolic profiling of the substrates(2-hydroxynaringenin,phloretin,and apigenin)and products(vitexin,isovitexin,vicenin-2,nothofagin,3’,5’-di-C-glucosylphloretin,and cosmosiin)in different tissues showed that vicenin-2 was the most abundant product of this novel enzyme.Cosmosiin was detected in flowers and flower buds.We also established that DcaCGT functions expanded throughout the evolution of D.catenatum.Residual OGT activity may help D.catenatum resist drought stress.Our study illustrates the function,origin,and differentiation of DcaCGT and provides insights into glycosylation and molecular propagation processes,which can be used to improve the production of flavonoids by the cultivated medicinal plant D.catenatum.Zhiyao Ren Xiaoyu Ji Zhenbin Jiao Yingyi Luo Guo-Qiang Zhang Shengchang Tao Zhouxi Lei Jing Zhang Yuchen Wang Zhong-Jian Liu Gang Wei 2020Horticulture Research2020,7,1:5
15Spatiotemporal variations of nitrate sources and dynamics in a typical agricultural riverine system under monsoon climate显示文摘Nitrogen pollution is a serious environmental issue in the Danjiangkou Reservoir region(DRR),the water source of the South-to-North Water Diversion Project of China.In this research,seasonal surveys and a bi-weekly time series survey were conducted in the Qihe River Basin,one of the most densely populated agricultural basins in the DRR.Hydrochemical compositions(NO3^-Cl^-),dual isotopes(δD-H2O,δ^18O-H2O,δ^15N-NO3^-,andδ^18O-NO3^-),and a Markov Chain Monte Carlo isotope mixing model were jointly applied to unravel the sources,migrations,and transformations of the nitrate(NO3^-)in the basin.It was revealed that the mixing between different sources was the main process controlling the isotopic compositions of the riverine NO3the upper-middle reaches.In contrast,denitrification occurred in the lower reaches.For the first time,the sources of NO3^-quantified at a basin scale in the DRR.Overall,the river transported 484.2 tons/year of NO3^-N to the reservoir,of which 32.6%,36.4%,28.0%,and 3.0%was from soil organic nitrogen,chemical fertilizer,residential sewage and atmospheric precipitation,respectively.The NO3^-N fluxes of the different sources were regulated by the monsoon climate and anthropogenic activities.For example,high precipitation and intense fertilization resulted in severe nonpoint source pollution.Denitrification thrived in soils and reservoirs in wet seasons.Temperature could regulate the migration,nitrification and denitrification processes.Based on the results,we suggest that the management strategies dealing with nitrogen pollution issue in the DRR should follow the specific spatiotemporal characteristics of NO3migration and transformation mechanisms.Hao Jiang Wenjing Liu Jiangyi Zhang Li Zhou Xiaode Zhou Ke Pan Tong Zhao Yuchen Wang Zhifang Xu 2020Journal of Environmental Sciences2020,32,7:5
16Engineering osteoarthritic cartilage model through differentiating senescent human mesenchymal stem cells for testing disease-modifying drugs显示文摘Significant cellular senescence has been observed in cartilage harvested from patients with osteoarthritis(OA).In this study,we aim to develop a senescence-relevant OA-like cartilage model for developing disease-modifying OA drugs(DMOADs).Spe-cifically,human bone marrow-derived mesenchymal stromal cells(MSCs)were expanded in vitro up to passage 10(P10-MSCs).Following their senescent phenotype formation,P10-MSCs were subjected to pellet culture in chondrogenic medium.Results from qRT-PCR,histology,and immunostaining indicated that cartilage generated from P10-MSCs displayed both senescent and OA-like phenotypes without using other OA-inducing agents,when compared to that from normal passage 4(P4)-MSCs.Interestingly,the same gene expression differences observed between P4-MSCs and P10-MSC-derived cartilage tissues were also observed between the preserved and damaged OA cartilage regions taken from human samples,as demonstrated by RNA sequencing data and other analysis methods.Lastly,the utility of this senescence-initiated OA-like cartilage model in drug development was assessed by testing several potential DMOADs and senolytics.The results suggest that pre-existing cellular senescence can induce the generation of OA-like changes in cartilage.The P4-and P10-MSCs derived cartilage models also represent a novel platform for predicting the efficacy and toxicity of potential DMOADs on both preserved and damaged cartilage in humans.Ning Wang Yuchen He Silvia Liu Meagan J.Makarcyzk Guanghua Lei Alexander Chang Peter G Alexander Tingjun Hao Anne-Marie Padget Nuria de Pedro Tsapekos Menelaos Hang Lin 2022Science China(Life Sciences)2022,65,2:5
17Chromatin remodeling factor lymphoid.specific helicase inhibits ferroptosis through lipid metabolic genes in lung cancer progression显示文摘Ferroptosis, a novel mode of non-apoptotic cell death,involves a metabolic dysfunction that results in the production of iron-dependent reactive oxygen species (ROS),an iron carrier protein (transferrin), intracellular metabolic process, and related regulators (e.g., p53 protein).Previous studies have linked ferroptosis with oncogenic Ras [1], and p53 tumor suppressor positively regulates ferroptosis by transcriptionally inhibiting the expression of the cysteine/glutamate antiporter, which is encoded by the SLC7A11 gene in human [1, 2]. Whether other factors such as epigenetic factors are involved in the process remains less known.Chromatin modifier lymphoid specific helicase (LSH)contributes to the malignant progression of nasopharyngeal carcinoma and glioma [3]. We recently indicated that LSH was shown to co-operate with partners, such as G9a, to drive cancer progression [4, 5].Yiqun Jiang Yuchen He Shuang Liu Yongguang Tao 2017Chinese Journal of Cancer2017,36,12:4
18Recent development on synthetic biological devices treating bladder cancer显示文摘Synthetic biology is an emerging field focusing on engineering genetic devices and biomolecular systems for a variety of applications from basic biology to biotechnology and medicine.Thanks to the tremendous advances in genomics and the chemical synthesis of DNA in the past decade,scientists are now able to engineer genetic devices and circuits for cancer research and intervention,which offer promising therapeutic strategies for cancer treatment.In this article,we provide a systemic review on recent development achieved by the synthetic biologists,oncologists and clinicians of one National“973”Plan.We expand the synthetic biology toolkits involving DNA,RNA and protein bio-parts to explore various issues in cancer research,such as elucidation of mechanisms and pathways,creation of new diagnostic tools and invention of novel therapeutic approaches.We claimed that the Chinese synthetic biologists are promoting the basic research productions of tumor synthetic biology into the clinic.Zhicong Chen Anbang He Yuchen Liu Weiren Huang Zhiming Cai 2016Synthetic and Systems Biotechnology2016,1,4:4
19Application of high-throughput first-principles calculations in ceramic innovation显示文摘Recent technical progress in the industry has led to an urgent requirement on new materials with enhanced multi-properties.To meet this multi-property requirement,the materials consisting of three and more elements have attracted increasing attention.However,facing to the nearly unknown huge multi-component materials system,the traditional trial and error method cannot provide sufficient data efficiently.Therefore,an efficient material innovation strategy is significant.The first-principles calculation based on the density functional theory is a powerful tool for both the accurate prediction of material properties and the identification of its underlying thermodynamics and dynamics.At the same time,the advances of computational methods and computer calculation abilities that are orders of magnitude faster than before make the high throughput first-principles calculations popular.At present,the simulation-assisted material design has become a main branch in the material research field and a great many successes have been made.In this article,the advances of the high throughput first-principles calculations are reviewed to show the achievements of the first-principles calculations and guide the future directions of its applications in ceramics.Bin Liu Juanli Zhao Yuchen Liu Jianqi Xi Qian Li Huimin Xiang Yanchun Zhou 2021Journal of Materials Science & Technology2021,,29:4
20Analog Optical Computing for Artificial Intelligence显示文摘The rapid development of artificial intelligence(AI)facilitates various applications from all areas but also poses great challenges in its hardware implementation in terms of speed and energy because of the explosive growth of data.Optical computing provides a distinctive perspective to address this bottleneck by harnessing the unique properties of photons including broad bandwidth,low latency,and high energy efficiency.In this review,we introduce the latest developments of optical computing for different AI models,including feedforward neural networks,reservoir computing,and spiking neural networks(SNNs).Recent progress in integrated photonic devices,combined with the rise of AI,provides a great opportunity for the renaissance of optical computing in practical applications.This effort requires multidisciplinary efforts from a broad community.This review provides an overview of the state-of-the-art accomplishments in recent years,discusses the availability of current technologies,and points out various remaining challenges in different aspects to push the frontier.We anticipate that the era of large-scale integrated photonics processors will soon arrive for practical AI applications in the form of hybrid optoelectronic frameworks.Jiamin Wu Xing Lin Yuchen Guo Junwei Liu Lu Fang Shuming Jiao Qionghai Dai 2022Engineering2022,8,3:4
