| 2 | Single-photon computational 3D imaging at 45 km显示文摘Single-photon light detection and ranging(lidar)offers single-photon sensitivity and picosecond timing resolution,which is desirable for high-precision three-dimensional(3 D)imaging over long distances.Despite important progress,further extending the imaging range presents enormous challenges because only a few echo photons return and are mixed with strong noise.Here,we tackled these challenges by constructing a high-efficiency,low-noise coaxial single-photon lidar system and developing a long-range-tailored computational algorithm that provides high photon efficiency and good noise tolerance.Using this technique,we experimentally demonstrated active single-photon 3 D imaging at a distance of up to 45 km in an urban environment,with a low return-signal level of^1 photon per pixel.Our system is feasible for imaging at a few hundreds of kilometers by refining the setup,and thus represents a step towards low-power and high-resolution lidar over extra-long ranges. | ZHENG-PING LI XIN HUANG YUAN CAO BIN WANG YU-HUAI LI WEIJIE JIN CHAO YU JUN ZHANG QIANG ZHANG CHENG-ZHI PENG FEIHU XU AND JIAN-WEI PAN | 2020 | Photonics Research2020，8，9： | 24 |
| 3 | Comprehensive analysis of NAC transcription factors in diploid Gossypium: sequence conservation and expression analysis uncover their roles during fiber development显示文摘Determining how function evolves following gene duplication is necessary for understanding gene expansion.Transcription factors(TFs)are a class of proteins that regulate gene expression by binding to specific cis-acting elements in the promoters of target genes,subsequently activating or repressing their transcription.In the present study,we systematically examined the functional diversification of the NAC transcription factor(NAC-TFs)family by analyzing their chromosomal location,structure,phylogeny,and expression pattern in Gossypium raimondii(Gr)and G.arboreum(Ga).The 145 and 141 NAC genes identified in the Gr and Ga genomes,respectively,were annotated and divided into 18 subfamilies,which showed distinct divergence in gene structure and expression patterns during fiber development.In addition,when the functional parameters were examined,clear divergence was observed within tandem clusters,which suggested that subfunctionalization had occurred among duplicate genes.The expression patterns of homologous gene pairs also changed,suggestive of the diversification of gene function during the evolution of diploid cotton.These findings provide insights into the mechanisms underlying the functional differentiation of duplicated NAC-TFs genes in two diploid cotton species. | Haihong Shang Zhongna Wang Changsong Zou Zhen Zhang Weijie Li Junwen Li Yuzhen Shi Wankui Gong Tingting Chen Aiying Liu Juwu Gong Qun Ge Youlu Yuan | 2016 | Science China(Life Sciences)2016，59，2： | 12 |

| 6 | Sirt1-ROS-TRAF6 Signaling-Induced Pyroptosis Contributes to Early Injury in Ischemic Mice显示文摘Stroke is an acute cerebro-vascular disease with high incidence and poor prognosis,most commonly ischemic in nature.In recent years,increasing attention has been paid to inflammatory reactions as symptoms of a stroke.However,the role of inflammation in stroke and its underlying mechanisms require exploration.In this study,we evaluated the inflammatory reactions induced by acute ischemia and found that pyroptosis occurred after acute ischemia both in vivo and in vitro,as determined by interleukin-1β,apoptosis-associated speck-like protein,and caspase-1.The early inflammation resulted in irreversible ischemic injury,indicating that it deserves thorough investigation.Meanwhile,acute ischemia decreased the Sirtuin 1(Sirtl)protein levels,and increased the TRAF6(TNF receptor associated factor 6)protein and reactive oxygen species(ROS)levels.In further exploration,both Sirtl suppression and TRAF6 activation were found to contribute to this pyroptosis.Reduced Sirtl levels were responsible for the production of ROS and increased TRAF6 protein levels after ischemic exposure.Moreover,N-acetyl-L-cysteine,an ROS scavenger,suppressed the TRAF6 accumulation induced by oxygen-glucose deprivation via suppression of ROS bursts.These phenomena indicate that Sirtl is upstream of ROS,and ROS bursts result in increased TRAF6 levels.Further,the activation of Sirtl during the period of ischemia reduced ischemiainduced injury after 72 h of reperfusion in mice with middle cerebral artery occlusion.In sum,these results indicate that pyroptosis-dependent machinery contributes to the neural injury during acute ischemia via the Sirt1-ROS-TRAF6 signaling pathway.We propose that inflammatory reactions occur soon after oxidative stress and are detrimental to neuronal survival;this provides a promising therapeutic target against ischemic injuries such as a stroke. | Weijie Yan Wei Sun Jiahui Fan Haiqing Wang Song Han Junfa Li Yanling Yin | 2020 | Neuroscience Bulletin2020，36，8： | 9 |
| 7 | Efficient manipulations of circularly polarized terahertz waves with transmissive metasurfaces显示文摘The unrestricted control of circularly polarized(CP)terahertz(THz)waves is important in science and applications,but conventional THz devices suffer from issues of bulky size and low efficiency.Although Pancharatnam-Berry(PB)metasurfaces have shown strong capabilities to control CP waves,transmission-mode PB devices realized in the THz regime are less efficient,limiting their applications in practice.Here,based on Jones matrix analysis,we design a trilayer structure(thickness of ~λ/5)and experimentally demonstrate that the structure can serve as a highly efficient transmissive meta-atom(relative efficiency of ~90%)to build PB metadevices for manipulating CP THz waves.Two ultrathin THz metadevices are fabricated and experimentally characterized with a z-scan THz imaging system.The first device can realize a photonic spin Hall effect with an experimentally demonstrated relative efficiency of ~90%,whereas the second device can generate a high-quality background-free CP Bessel beam with measured longitudinal and transverse field patterns that exhibit the nondiffracting characteristics of a Bessel beam.All the experimental results are in excellent agreement with full-wave simulations.Our results pave the way to freely manipulate CP THz beams,laying a solid basis for future applications such as biomolecular control and THz signal transportation. | Min Jia Zhuo Wang Heting Li Xinke Wang Weijie Luo Shulin Sun Yan Zhang Qiong He Lei Zhou | 2019 | Light(Science & Applications)2019，8，1： | 9 |
| 8 | Activation of Rev-erbα attenuates lipopolysaccharide-induced inflammatory reactions in human endometrial stroma cells via suppressing TLR4-regulated NF-κB activation显示文摘Perturbation of the circadian rhythm damages the biological characteristics of cells and leads to their dysfunction. Rev-erbα, an important gene in the transcription-translation loop of circadian rhythm, is involved in regulating the balance between pro-inflammation and anti-inflammation. The disruption of this balance in human endometrial stroma cells (hESCs) destroys their biological behavior function in maintaining the menstrual cycle and embryonic implantation. Whether pharmacological modulation of Rev-erbα affects the inflammation of hESCs remains unclear. In this study, we treated hESCs with lipopolysaccharide (LPS) and found that LPS treatment increased the mRNA levels of pro-inflammatory cytokines, such as interleukin (IL)-1β, IL-6, IL-8, IL-18, and TNFα, and the secretion of IL-6. SR9009, a Rev-erbα agonist, significantly alleviated the LPS-induced production of pro-inflammatory cytokines in hESCs. Meanwhile, knockdown of Rev-erbα increased the expressions of IL-1β, IL-6, and IL-8, accompanied by an increased mRNA level of the core clock gene Bmal1. Western blot analysis showed that SR9009 inhibited the expression of toll-like receptor 4 (TLR4) and the activation of NF-κB induced by LPS. All these findings suggested that pharmacological activation of Rev-erbα attenuated the LPS-induced inflammatory response of hESCs by suppressing TLR4-regulated NF-κB activation. This study may provide a strategy for preventing inflammation-related endometrial dysfunction and infertility or recurrent implantation failure. | Weijie Zhao Liyuan Cui Xixi Huang Songcun Wang Dajin Li Liping Li Yan Sun Meirong Du | 2019 | Acta Biochimica et Biophysica Sinica2019，51，9： | 8 |

| 11 | Application of a novel backwashing process in upflow biological aerated filter显示文摘To improve the efficiency of backwashing in upflow biological aerated filter (BAF), a novel backwashing process named air-water siphon backwashing (AWSB) was proposed and applied on laboratory scale. The effects of backwashing on turbidity and suspended solid (SS) in backwashing efluent using this new backwashing process were compared with those of traditional backwashing process, namely air-water backwashing (AWB). In AWB, the turbidity of backwashing efluent maintained 100 NUT when consumed 60 min and 10.5 L water. However, in AWSB, it declined to 44 NUT, consumed 40 min, and 7 L water. The COD removal of BAF after backwashing was also analyzed. The average removal rate of COD in the reactor backwashed by AWB and AWSB was 89.34% and 90.91%, respectively. Compared with AWB, the backwashing interval had been prolonged 35%. The volume of backwashing water in that AWSB was only 66.7% of that in AWB. The results demonstrated that AWSB required less water and took shorter backwashing time relative to AWB to achieve the same turbidity of backwashing efluent, and AWSB was more effective in removing fouling than that of AWB. More significant advantage of AWSB was that the backwashing interval was effectively prolonged. | Jinshui Yang Weijie Liu Baozhen Li Hongli Yuana Meiping Tong Jinsong Gao | 2010 | Journal of Environmental Sciences2010，22，3： | 7 |
| 12 | Artificial Intelligence for Edge Service Optimization in Internet of Vehicles:A Survey显示文摘The Internet of Vehicles(IoV)plays a crucial role in providing diversified services because of its powerful capability of collecting real-time information.Generally,collected information is transmitted to a centralized resourceintensive cloud platform for service implementation.Edge Computing(EC)that deploys physical resources near road-side units is involved in IoV to support real-time services for vehicular users.Additionally,many measures are adopted to optimize the performance of EC-enabled IoV,but they hardly help make dynamic decisions according to real-time requests.Artificial Intelligence(AI)is capable of enhancing the learning capacity of edge devices and thus assists in allocating resources dynamically.Although extensive research has employed AI to optimize EC performance,summaries with relative concepts or prospects are quite few.To address this gap,we conduct an exhaustive survey about utilizing AI in edge service optimization in IoV.Firstly,we establish the general condition and relative concepts about IoV,EC,and AI.Secondly,we review the edge service frameworks for IoV and explore the use of AI in edge server placement and service offloading.Finally,we discuss a number of open issues in optimizing edge services with AI. | Xiaolong Xu Haoyuan Li Weijie Xu Zhongjian Liu Liang Yao Fei Dai | 2022 | Tsinghua Science and Technology2022，27，2： | 7 |
| 13 | Two-dimensional ultrathin MoS2-modified black Ti^3+-TiO2 nanotubes for enhanced photocatalytic water splitting hydrogen production显示文摘Two-dimensional (2D) ultrathin MoS2-modified black Ti^3+-TiO2 nanotubes were fabricated using an electrospinning-hydrothermal treatment-reduction method.Bare TiO2 nanotubes were fabricated via electrospinning.Then,2D MoS2 lamellae were grown on the surface of the nanotubes and Ti^3+/Ov ions were introduced by reduction.The photocatalytic performance of the 2D MoS2/Ti^3+-TiO2 nanotubes was^15 times better than that of TiO2.The HER enhancement of the MoS2/Ti^3+-TiO2 nanotubes can be attributed to the Pt-like behavior of 2D MoS2 and the presence of Ti^3+-ions,which facilitated the quick diffusion of the photogenerated electrons to water,reducing the H2 activation barrier.The presence of Ov ions in the nanotubes and their hollow structure increased their solar utilization. | Wei Ou Jiaqi Pan Yanyan Liu Shi Li Hongli Li Weijie Zhao Jingjing Wang Changsheng Song Yingying Zheng Chaorong Li | 2020 | Journal of Energy Chemistry2020，29，4： | 7 |
| 14 | Synergistic effect of MXene on the flame retardancy and thermal degradation of intumescent flame retardant biodegradable poly(lactic acid)composites显示文摘The effect of Ti3C2 MXene nanosheets on the intumescent flame retardant(IFR)poly(lactic acid)(PLA)composites was investigated among a series of PLA/IFR/MXene,which were prepared by melt blending 0-2.0 wt%MXene,10.0 wt%-12.0 wt%IFR and PLA together.The results of limiting oxygen index(LOI)and vertical burning(UL-94)discover that the combination of 0.5 wt%MXene and 11.5 wt%IFR synergistically improves the fire safety of PLA to reach UL-94 V-0 rating with LOI value of 33.0%.The PLA/IFR/MXene composites perform an obvious reduction in peak of heat release rate(HRR)in cone calorimeter tests(CCTs).Furthermore,the carbon residues after CCTs were characterized by scanning electron microscope(SEM),laser Raman spectroscopy(LRS),X-ray diffraction(XRD)and X-ray photoelectron spectroscopy(XPS).It is demonstrated that both the titanium composition of the MXene structure and the characteristics of the two-dimensional material enhance the PLA/IFR/MXene composite materials’ability to produce a dense barrier layer to resist burnout during thermal degradation. | Haowei Huang Dexuan Dong Weijie Li Xinya Zhang Li Zhang Ying Chen Xinxin Sheng Xiang Lu | 2020 | Chinese Journal of Chemical Engineering2020，28，7： | 7 |
| 15 | Analysis of Genetic Diversity and Differentiation of Seven Stocks of Litopenaeus vannamei Using Microsatellite Markers显示文摘Seven microsatellite markers were used to evaluate the genetic diversity and differentiation of seven stocks of Litopenaeus vannamei, which were introduced from Central and South America to China. All seven microsatellite loci were polymorphic, with polymorphism information content(PIC) values ranging from 0.593 to 0.952. Totally 92 alleles were identified, and the number of alleles(Na) and effective alleles(Ne) varied between 4 and 21 and 2.7 and 14.6, respectively. Observed heterozygosity(Ho) values were lower than the expected heterozygosity(He) values(0.526–0.754), which indicated that the seven stocks possessed a rich genetic diversity. Thirty-seven tests were detected for reasonable significant deviation from Hardy-Weinberg equilibrium. Fis values were positive at five loci, suggesting that there was a relatively high degree of inbreeding within stocks. Pairwise Fst values ranged from 0.0225 to 0.151, and most of the stock pairs were moderately differentiated. Genetic distance and cluster analysis using UPGMA revealed a close genetic relationship of L. vannamei between Pop2 and Pop3. AMOVA indicated that the genetic variation among stocks(11.3%) was much lower than that within stocks(88.7%). Although the seven stocks had a certain degree of genetic differentiation and a rich genetic diversity, there is an increasing risk of decreased performance due to inbreeding in subsequent generations. | ZHANG Kai WANG Weiji LI Weiya ZHANG Quanqi KONG Jie | 2014 | Journal of Ocean University of China2014，13，4： | 7 |

| 17 | Efficacy of platinum in advanced triple-negative breast cancer with germline BRCA mutation determined by next generation sequencing显示文摘Objective:To compare the efficacy of platinum-and non-platinum-based regimens as first-line treatment for advanced triple-negative breast cancer(TNBC)and analyze the relationship between their efficacy and BRCA gene status.Methods:Retrospectively analyze clinical data of 220 patients diagnosed pathologically with advanced TNBC and treated at the Department of Breast Oncology,Peking University Cancer Hospital from 2013 to 2018 and evaluate the efficacy of chemotherapy.A total of 114 patients had BRCA1/2 gene tested by next generation sequencing(NGS)using peripheral blood,and we analyzed the correlation between their efficacy and BRCA1/2 gene status.Results:Non-platinum-based chemotherapy(NPCT)was administered to 129 and platinum-based chemotherapy(PBCT)to 91 study patients.The clinical benefit rate(CBR)and median progression-free survival(PFS)were not statistically different between NPCT and PBCT groups.The median overall survival(OS)was 30.0 and 22.5 months for PBCT and NPCT group,respectively[P=0.090,hazard ratios(HR)=0.703].BRCA status was assessed in 114 patients,14 of whom had deleterious germline BRCA1/2(g BRCA)mutations(seven in each group).In PBCT group,the CBR was 85.7%and 35.1%for patients with and without deleterious g BRCA mutations,respectively(P=0.039).The median PFS were 14.9 and 5.3 months and median OS were 26.5 and 15.5 months for patients with and without deleterious g BRCA mutations,respectively(P=0.001,P=0.161,respectively).Patients in PBCT group had significantly greater rates of grade 3-4 anemia(5.5%vs.0%)and thrombocytopenia(8.8%vs.0%),whereas palmar-plantar erythrodysesthesia(12.4%vs.0%)and peripheral neuropathy(8.6%vs.1.1%)occurred more frequently in NPCT group.Conclusions:Platinum-based regimens are more effective in patients with deleterious g BRCA mutations,but no difference in patients without BRCA gene mutations,so non-platinum is an option in patients without BRCA gene mutations considering the toxicity and side effect.And we recommend that patients with advanced TNBC should have BRCA gene test. | Nan Wang Kun Li Wenfa Huang Weiyao Kong Xiaoran Liu Weijie Shi Feng Xie Hanfang Jiang Guohong Song Lijun Di Quanren Wang Jianjun Yu Huiping Li | 2020 | Chinese Journal of Cancer Research2020，32，2： | 7 |
| 18 | Multidimensional stability of V-shaped traveling fronts in the Allen-Cahn equation显示文摘This paper is concerned with the multidimensional asymptotic stability of V-shaped traveling fronts in the Allen-Cahn equation under spatial decaying initial values.We frst show that V-shaped traveling fronts are asymptotically stable under the perturbations that decay at infnity.Then we further show that there exists a solution that oscillates permanently between two V-shaped traveling fronts,which indicates that V-shaped traveling fronts are not always asymptotically stable under general bounded perturbations.Our main technique is the supersolutions and subsolutions method coupled with the comparison principle. | SHENG WeiJie LI WanTong WANG ZhiCheng | 2013 | Science China Mathematics2013，56，10： | 5 |
| 19 | A novel selective autophagy receptor,CCDC50,delivers K63 polyubiquitination-activated RIG-I/MDA5 for degradation during viral infection显示文摘Autophagy is a con served process that delivers cytosolic substa nces to the lysosome for degradatio n,but its direct role in the regulation of antiviral inn ate immu nity remains poorly un derstood.Here,through high-throughput screeni ng,we discovered that CCDC50 functions as a previously unknown autophagy receptor that negatively regulates the type I interferon(IFN)signaling pathway initiated by RIG-I-like receptors(RLRs),the sensors for RNA viruses.The expression of CCDC50 is enhanced by viral infection,and CCDC50 specifically recognizes K63-polyubiquitinated RLRs,thus delivering the activated RIG-I/MDA5 for autophagic degradation.The associatio n of CCDC50 with phagophore membrane protei n LC3 is con firmed by crystal structure analysis.In contrast to other known autophagic cargo receptors that associate with either the LIR-docking site(LDS)or the UIMdocking site(UDS)of LC3,CCDC50 can bind to both LDS and UDS,representing a new type of cargo receptor.In mouse models with RNA virus infection,CCDC50 deficiency reduces the autophagic degradation of RIG-I/MDA5 and promotes type I IFN responses,resulting in enhaneed viral resistance and improved survival rates.These results reveal a new link between autophagy and antiviral innate immune resp on ses and provide additional in sights into the regulatory mecha nisms of RLR-mediated antiviral signaling. | Panpan Hou Kongxiang Yang Penghui Jia Lan Liu Yuxin Lin Zibo Li Jun Li Shuliang Chen Shuting Guo Ji'An Pan Junyu Wu Hong Peng Weijie Zeng Chunmei Li Yingfang Liu Deyin Guo | 2021 | Cell Research2021，31，1： | 5 |
| 20 | Spatial variability effect of internal friction angle on the post-failure behavior of landslides using a random and non-Newtonian fluid based SPH method显示文摘This study proposed a random Smoothed Particle Hydrodynamics method for analyzing the post-failure behavior of landslides,which is based on the Karhunen-Loeve(K-L) expansion,the non-Newtonian fluid model,and the OpenMP parallel framework.Then,the applicability of this method was validated by comparing the generated random field with theoretical result and by simulating the post-failure process of an actual landslide.Thereafter,an illustrative landslide example was created and simulated to obtain the spatial variability effect of internal friction angle on the post-failure behavior of landslides under different coefficients of variation(COVs) and correlation lengths(CLs).As a conclusion,the reinforcement with materials of a larger friction angle can reduce the runout distance and impact the force of a landslide.As the increase of COV,the distribution range of influence zones also increases,which indicates that the deviation of influence zones becomes large.In addition,the correlation length in Monte Carlo simulations should not be too small,otherwise the variation range of influence zones will be underestimated. | Weijie Zhang Jian Ji Yufeng Gao Xiaoyu Li Chunshun Zhang | 2020 | Geoscience Frontiers2020，11，4： | 5 |
