3Room temperature ferromagnetism in ultra-thin van der Waals crystals of 1T-CrTe2显示文摘Although many emerging new phenomena have been unraveled in two dimensional(2D)materials with long-range spin orderings,the usually low critical temperature in van der Waals(vdW)magnetic material has thus far hindered the related practical applications.Here,we show that ferromagnetism can hold above 300 K in a metallic phase of 1T-CrTe2 down to the ultra-thin limit.It thus makes CrTe2 so far the only known exfoliated ultra-thin vdW magnets with intrinsic long-range magnetic ordering above room temperature.An in-plane room-temperature negative anisotropic magnetoresistance(AMR)was obtained in ultra-thin CrTe2 devices,with a sign change in the AMR at lower temperature,with−0.6%and+5%at 300 and 10 K,respectively.Our findings provide insights into magnetism in ultra-thin CrTe2,expanding the vdW crystals toolbox for future room-temperature spintronic applications.Xingdan Sun Wanying Li Xiao Wang Qi Sui Tongyao Zhang Zhi Wang Long Liu Da Li Shun Feng Siyu Zhong Hanwen Wang Vincent Bouchiat Manuel Nunez Regueiro Nicolas Rougemaille Johann Coraux Anike Purbawati Abdellali Hadj-Azzem Zhenhua Wang Baojuan Dong Xing Wu Teng Yang Guoqiang Yu Bingwu Wang Zheng Han Xiufeng Han Zhidong Zhang 2020Nano Research2020,13,12:6

5Phase recovery and holographic image reconstruction using deep learning in neural networks显示文摘Phase recovery from intensity-only measurements forms the heart of coherent imaging techniques and holography.In this study,we demonstrate that a neural network can learn to perform phase recovery and holographic image reconstruction after appropriate training.This deep learning-based approach provides an entirely new framework to conduct holographic imaging by rapidly eliminating twin-image and self-interference-related spatial artifacts.This neural network-based method is fast to compute and reconstructs phase and amplitude images of the objects using only one hologram,requiring fewer measurements in addition to being computationally faster.We validated this method by reconstructing the phase and amplitude images of various samples,including blood and Pap smears and tissue sections.These results highlight that challenging problems in imaging science can be overcome through machine learning,providing new avenues to design powerful computational imaging systems.Yair Rivenson Yibo Zhang Harun Günaydın Da Teng Aydogan Ozcan 2017Light(Science & Applications)2017,6,1:5
6Structural impairment patterns in peripapillary retinal fiber layer and retinal ganglion cell layer in mitochondrial optic neuropathies显示文摘AIM:To evaluate the structural injure patterns in peripapillary retinal fiber layer (pRNFL), retinal ganglion cell layer (RGCL) and their correlations to visual function in various mitochondrial optic neuropathies (MON) to offer help to their differential diagnosis.METHODS:Totally 32 MON patients (60 eyes) were recruited within 6mo after clinical onsets, including 20 Leber hereditary optic neuropathy (LHON) patients (37eyes), 12 ethambutol-induced optic neuropathy (EON)patients (23 eyes), and 41 age-gender matched healthy controls (HC, 82 eyes). All subjects had pRNFL and RGCL examinations with optic coherence tomography (OCT) and visual function tests.RESULTS:In the early stages of MON, the temporal pRNFL thickness decreased (66.09±22.57μm), but increased in other quadrants, compared to HC (76.95±14.81μm). The other quadrants remaining stable for LHON and EON patients besides the second hour sector of pRNFL thickness reduced and the temporal pRNFL decreased (56.78±15.87μm) for EON. Total macular thickness in MON reduced remarkably(279.25±18.90μm; P=0.015), which mainly occurring in the inner circle (3 mm diameter of circle) and the nasal temporal sectors in the outer circle (5.5 mm diameter of circle), in contrast to those in HC. RGCL thickness reduced in each sector of the macula (61.90±8.73μm; P≤0.001). It strongly showed the correlationship of best corrected visual acuity (R=0.50, P=0.0003) and visual field injury (R=0.54,P=0.0002) in MON patients.CONCLUSION:OCT is a potential tool for detecting structural alterations in the optic nerves of various MON. Different types of MON may have different damage patterns.Da Teng Chun-Xia Peng Hai-Yan Qian Li Li Wei Wang Jun-Qing Wang Bing Chen Huan-Fen Zhou Shi-Hui Wei 2018International Journal of Ophthalmology(English edition)2018,11,10:5

8Granular porous calcium carbonate particles for scalable and high-performance solar-driven thermochemical heat storage显示文摘Calcium carbonate is promising thermochemical heat storage material for next-generation solar power systems due to its high energy storage density,low cost,and high operation temperature.Researchers have tried to improve energy storage performances of calcium carbonate recently,but most researches focus on powders,which are not suitable for scalable applications.Here,novel granular porous calcium carbonate particles with very high solar absorptance,energy storage density,abrasive resistances,and energy storage rate are proposed for direct solar thermochemical heat storage.The average solar absorptance is improved by 234%compared with ordinary particles.Both cycle stability and abrasive resistances are excellent with almost no decay of energy storage density over 25 cycles nor apparent particle weight loss over 24 h of continuous operation insides a planetary ball mill.In addition,the decomposition temperature is reduced by 2.8%–5.6%while the reaction rate of heat storage is enhanced by 80%–205%depending on the CO_(2) partial pressure.The decomposition process of doped granular porous CaCO_(3) particles is found to involve three overlapping processes.This work provides new routes to achieve scalable direct solar thermochemical heat storage for next-generation high-temperature solar power systems.SONG Chao LIU XiangLei XUAN YiMin ZHENG HangBin GAO Ke TENG Liang DA Yun LI Chuan LI YongLiang DING YuLong 2021Science China(Technological Sciences)2021,64,10:4
9Novel Kriging-Based Decomposed-Coordinated Approach for Estimating the Clearance Reliability of Assembled Structures显示文摘Turbine blisks are assembled using blades,disks and casings.They can endure complex loads at a high temperature,high pressure and high speed.The safe operation of assembled structures depends on the reliability of each component.Monte Carlo(MC)simulation is commonly used to analyze structural reliability,but this method needs to run thousands of computations.In order to assess the clearance reliability of assembled structures in an efficient and precise manner,the novel Kriging-based decomposed-coordinated(DC)(DCNK)approach is proposed by integrating the DC strategy,the Kriging model and the importance sampling-based Markov chain(MCIS)technique.In this method,the DC strategy is used to decompose a multi-objective problem into many single-objective problems.The relationships between these many single-objectives and the overall objective are then coordinated.The Kriging model is applied to establish the limit state functions of the single-objectives and multi-objective problems,while the MCIS method is used to assess the structural assembled clearance reliability.Moreover,a highly nonlinear complex compound function is first utilized to verify the DCNK model from a mathematical perspective.Then,the reliability of an aeroengine high-pressure turbine(HPT)blade-tip radial running clearance(BTRRC)is analyzed to validate the DCNK approach by considering thermo-structural interaction.The analytical results show that the reliability is 0.9976 when the allowance value of the BTTRC is 1.7650×10^(−3)m.Compared with different methodologies(including direct simulation,the classical Kriging model,and the weighted response surface method(WRSM)),the proposed method holds obvious advantages in computing time and precision,as well as simulation efficiency and precision.The efforts of this paper provide a useful approach to analyzing assembled clearance reliability and contribute to the development of structural reliability theory.Da Teng Yunwen Feng Cheng Lu Chengwei Fei Jiaqi Liu Xiaofeng Xue 2021Computer Modeling in Engineering & Sciences2021,,11:2

11circBIRC6 contributes to the development of non-small cell lung cancer via regulating microRNA-217/amyloid beta precursor protein binding protein 2 axis显示文摘Background:Circular RNAs(circRNAs)are considered to be important regulators in cancer biology.In this study,we focused on the effect of circRNA baculoviral inhibitor of apoptosis protein(IAP)repeat containing 6(circBIRC6)on non-small cell lung cancer(NSCLC)progression.Methods:The NSCLC and adjacent non-tumor tissues were collected at Shanghai Ninth People's Hospital.Quantitative real-time polymerase chain reaction was conducted for assessing the levels of circBIRC6,amyloid beta precursor protein binding protein 2(APPBP2)messenger RNA(mRNA),baculoviral IAP repeat containing 6 mRNA(BIRC6),and microRNA-217(miR-217).Western blot assay was adopted for measuring the protein levels of APPBP2,E-cadherin,N-cadherin,and vimentin.Colony formation assay,transwell assay,and flow cytometry analysis were utilized for evaluating cell colony formation,metastasis,and apoptosis.Dualluciferase reporter assay and RNA immunoprecipitation assay were carried out to determine the interaction between miR-217 and circBIRC6 and APPBP2 in NSCLC tissues.The murine xenograft model assay was used to investigate the function of circBIRC6 in tumor formation in vivo.Differences were analyzed via Student's t test or one-way analysis of variance.Pearson's correlation coefficient analysis was used to analyze linear correlation.Results:CircBIRC6 was overexpressed in NSCLC tissues and cells.Knockdown of circBIRC6 repressed the colony formation and metastasis and facilitated apoptosis of NSCLC cells in vitro and restrained tumorigenesis in vivo.Mechanically,circBIRC6 functioned as miR-217 sponge to promote APPBP2 expression in NSCLC cells.MiR-217 inhibition rescued circBIRC6 knockdown-mediated effects on NSCLC cell colony formation,metastasis,and apoptosis.Overexpression of miR-217 inhibited the malignant phenotypes of NSCLC cells,while the effects were abrogated by elevating APPBP2.Conclusion:CircBIRC6 aggravated NSCLC cell progression by elevating APPBP2 via sponging miR-217,which might provide a fresh perspective on NSCLC therapy.Da Ni Jiping Teng Youshuang Cheng Zhijun Zhu Bufeng Zhuang Zhiyin Yang 2022Chinese Medical Journal2022,,6:2

17Profiling the pattern of the human T-cell receptorγδcomplementary determinant region 3 repertoire in patients with lung carcinoma via high-throughput sequencing analysis显示文摘γδT cells function as sentinels in early host responses to infections and malignancies.Specifically,γδT cells recognize tumor-associated stress antigens via T-cell receptor(TCR)γδand play important roles in the antitumor immune response.In this study,we characterized the pattern of the human TCRγδcomplementary determinant region 3(CDR3)repertoire in patients with lung carcinoma(LC)via high-throughput sequencing.The results showed that the diversity of CDR3δwas significantly reduced,and that of CDR3γwas unchanged in LC patients compared with healthy individuals;in addition,LC patients shared significantly more CDR3δsequences with each other than healthy individuals.The CDR3 length distribution and N-addition length distribution did not significantly differ between LC patients and healthy individuals.In addition,the CDR3 repertoire tended to use more Vδ2 and fewer Vδ1 germline gene fragments among LC patients.Moreover,we found a combination of four TCRγδrepertoire features that focus on CDR3δand can be used as a biomarker for LC diagnosis.Our research suggests that the TCRγδCDR3 repertoire changed in LC patients due to the antitumor immune response byγδT cells in vivo,and these changes primarily focus on the amplification of certain tumor-specific CDR3δclones among patients.This study demonstrates the role ofγδT cells from the TCRγδCDR3 repertoire in tumor immunity and lays the foundation for elucidating the mechanism underlying the function ofγδT cells in antitumor immunity.Hui Chen Mingjin Zou Da Teng Yu Hu Jianmin Zhang Wei He 2019Cellular & Molecular Immunology2019,16,3:1
18Deciphering the chromatin spatial organization landscapes during BMMSC differentiation显示文摘The differentiation imbalance in bone marrow mesenchymal stem cells(BMMSCs)is critical for the development of bone density diseases as the population ages.BMMSCs are precursor cells for osteoblasts and adipocytes;however,the chromatin organization landscapes during BMMSC differentiation remain elusive.In this study,we systematically delineate the four-dimensional genome and dynamic epigenetic atlas of BMMSCs by RNA sequencing,assay for transposase-accessible chromatin sequencing,and highthroughput chromosome conformation capture.The structure analyses reveal 17.5%common and28.5%-30%specific loops among BMMSCs,osteoblasts,and adipocytes.The subsequent correlation of genome-wide association studies and expression quantitative trait locus(e QTL)data with multi-omics analysis reveal 274 genes and 3634 single nucleotide polymorphisms(SNPs)associated with bone degeneration and osteoporosis(OP).We hypothesize that SNP mutations affect transcription factor(TF)binding sites,thereby affecting changes in gene expression.Furthermore,26 motifs,260 TFs,and 291SNPs are identified to affect the e QTL.Among these genes,DAAM2,TIMP2,and TMEM241 are found to be essential for diseases such as bone degeneration and OP and may serve as potential drug targets.Zhaowei Teng Yun Zhu Da Lin Qinggang Hao Qiaoning Yue Xiaochao Yu Shuo Sun Lihong Jiang Sheng Lu 2023Journal of Genetics and Genomics2023,50,4:1
