1Terahertz metasurface zone plates with arbitrary polarizations to a fixed polarization conversion显示文摘Metasurfaces that can realize the polarization manipulation of electromagnetic waves on the sub-wavelength scale have become an emerging research field.Here,a novel strategy of combining the metasurface and Fresnel zone plate to form a metasurface zone plate is proposed to realize the conversion from nearly arbitrary polarizations to a fixed polarization.Specifically,when one polarized wave is incident on adjacent ring zones constructed by different types of meta-atoms,the transmitted waves generated by odd-numbered and even-numbered ring zones converge at the same focus and superimpose to generate a fixed polarized wave.As function demonstrations,we have designed two types of metasurface zone plates:one is a focused linear polarizer,and the other can convert nearly arbitrary polarized waves into focused circularly polarized waves.The simulated and measured results are consistent with theoretical expectations,suggesting that the proposed concept is flexible and feasible.Our work provides an alternative platform for polarization manipulation and may vigorously promote the development of polarization photonic devices.Zhen Yue Jitao Li Jie Li Chenglong Zheng Jingyu Liu Guocui Wang Hang Xu Mingyang Chen Yating Zhang Yan Zhang Jianquan Yao 2022Opto-Electronic Science2022,1,3:9
2Dynamic phase assembled terahertz metalens for reversible conversion between linear polarization and arbitrary circular polarization显示文摘If a metalens integrates the circular polarization(CP)conversion function,the focusing lens together with circular-polariz-ing lens(CPL)in traditional cameras may be replaced by a metalens.However,in terahertz(THz)band,the reported metalenses still do not obtain the perfect and strict single-handed CP,because they were constructed via Pancharatnam-Berry phase so that CP conversion contained both left-handed CP(LCP)and right-handed CP(RCP)components.In this paper,a silicon based THz metalens is constructed using dynamic phase to obtain single-handed CP conversion.Also,we can rotate the whole metalens at a certain angle to control the conversion of multi-polarization states,which can simply manipulate the focusing for incident linear polarization(LP)THz wave in three polarization conversion states,in-cluding LP without conversion,LCP and RCP.Moreover,the polarization conversion behavior is reversible,that is,the THz metalens can convert not only the LP into arbitrary single-handed CP,but also the LCP and RCP into two perpen-dicular LP,respectively.The metalens is expected to be used in advanced THz camera,as a great candidate for tradi-tional CPL and focusing lens group,and also shows potential application in polarization imaging with discriminating LCP and RCP.Jitao Li Guocui Wang Zhen Yue Jingyu Liu Jie Li Chenglong Zheng Yating Zhang Yan Zhang Jianquan Yao 2022Opto-Electronic Advances2022,5,1:9
3Separate lateral parametrial lymph node dissection improves detection rate of parametrial lymph node metastasis in early-stage cervical cancer: 10-year clinical evaluation in a single center in China显示文摘Objective: To investigate the clinical significance of separate lateral parametrial lymph node dissection(LPLND) in improving parametrial lymph node(PLN) and its metastasis detection rate during radical hysterectomy for early-stage cervical cancer.Methods: From July 2007 to August 2017, 2,695 patients with cervical cancer in stage IB1-IIA2 underwent radical hysterectomy were included. Of these patients, 368 underwent separate dissection of PLNs using the LPLND method, and 2,327 patients underwent conventional radical hysterectomy(CRH). We compared the surgical parameters, PLN detection rate and PLN metastasis rate between the two groups.Results: Compared with CRH group, the rate of laparoscopic surgery was higher(60.3% vs. 15.9%, P<0.001),and the blood transfusion rate was lower(19.0% vs. 29.0%, P<0.001) in the LPLND group. PLNs were detected in 356 cases(96.7%) in the LPLND group, and 270 cases(11.6%) in the CRH group(P<0.001), respectively. The number of PLNs detected in the LPLND group was higher than that in the CRH group(median 3 vs. 1, P<0.001).The PLN metastases were detected in 25 cases(6.8%) in the LPLND group, and 18 cases(0.8%) in the CRH group(P<0.001), respectively. In multivariable analysis, LPLND is an independent factor not only for PLN detection [odds ratio(OR)=228.999, 95% confidence interval(95% CI): 124.661-420.664;P<0.001], but also for PLN metastasis identification(OR=10.867, 95% CI: 5.381-21.946;P<0.001).Conclusions: LPLND is feasible and safe. The surgical method significantly improves the detection rate of PLN and avoids omission of PLN metastasis during radical hysterectomy for early-stage cervical cancer.Dan Zhao Bin Li Shan Zheng Zhengjie Ou Yanan Zhang Yating Wang Shuanghuan Liu Gongyi Zhang Guangwen Yuan 2020Chinese Journal of Cancer Research2020,32,6:7
4Terahertz wavefront shaping with multi-channel polarization conversion based on all-dielectric metasurface显示文摘Polarization manipulation of electromagnetic wave or polarization multiplexed beam shaping based on metasurfaces has been reported in various frequency bands.However,it is difficult to shape the beam with multi-channel polarization conversion in a single metasurface.Here,we propose a new method for terahertz wavefront shaping with multi-channel polarization conversion via all-silicon metasurface,which is based on the linear shape birefringence effect in spatially interleaved anisotropic meta-atoms.By superimposing the eigen-and non-eigen-polarization responses of the two kinds of meta-atoms,we demonstrate the possibility for high-efficiency evolution of several typical polarization states with two independent channels for linearly polarized waves.The measured polarization conversion efficiency is higher than 70%in the range of 0.9–1.3 THz,with a peak value of 89.2%at 1.1 THz.In addition,when more other polarization states are incident,combined with the integration of sub-arrays,we can get more channels for both polarization conversion and beam shaping.Simulated and experimental results verify the feasibility of this method.The proposed method provides a new idea for the design of terahertz multi-functional metadevices.JIE LI CHENGLONG ZHENG JITAO LI GUOCUI WANG JINGYU LIU ZHEN YUE XUANRUO HAO YUE YANG FUYU LI TINGTING TANG YATING ZHANG YAN ZHANG JIANQUAN YAO 2021Photonics Research2021,9,10:5
5Precise fabrication of single-atom alloy co-catalyst with optimal charge state for enhanced photocatalysis显示文摘While the surface charge state of co-catalysts plays a critical role for boosting photocatalysis,studies on surface charge regulation via their precise structure control remain extremely rare.Herein,metal-organic framework(MOF)stabilized bimetallic Pd@Pt nanoparticles,which feature adjustable Pt coordination environment and a controlled structure from core-shell to single-atom alloy(SAA),have been fabricated.Significantly,apart from the formation of a Mott-Schottky junction in a conventional way,we elucidate that Pt surface charge regulation can be alternatively achieved by changing its coordination environment and the structure of the Pd@Pt co-catalyst,where the charge between Pd and Pt is redistributed.As a result,the optimized Pd10@Pt1/MOF composite,which involves an unprecedented SAA co-catalyst,exhibits exceptionally high photocatalytic hydrogen production activity,far surpassing its corresponding counterparts.Yating Pan Yunyang Qian Xusheng Zheng Sheng-Qi Chu Yijun Yang Chunmei Ding Xi Wang Shu-Hong Yu Hai-Long Jiang 2021National Science Review2021,8,1:4
6Circular dichroism-like response of terahertz wave caused by phase manipulation via all-silicon metasurface显示文摘Chiral metasurfaces based on asymmetric meta-atoms have achieved artificial circular dichroism(CD),spin-dependent wavefront control,near-field imaging,and other spin-related electromagnetic control.In this paper,we propose and experimentally verify a scheme for achieving high-efficiency chiral response similar to CD of terahertz(THz)wave via phase manipulation.By introducing the geometric phase and dynamic phase in an all-silicon metasurface,the spin-decoupled terahertz transmission is obtained.The giant circular dichroism-like effect in the transmission spectrum is observed by using a random phase distribution for one of the circular polarization components.More importantly,the effect can be adjusted when we change the area of the metasurface illuminated by an incident terahertz beam.In addition,we also demonstrate the spin-dependent arbitrary wavefront control of the transmitted terahertz wave,in which one of the circularly polarized components is scattered,while the other forms a focused vortex beam.Simulated and experimental results show that this method provides a new idea for spin selective control of THz waves.Jie Li Chenglong Zheng Guocui Wang Jitao Li Hongliang Zhao Yue Yang Zhang Zhang Maosheng Yang Liang Wu Jining Li Yating Zhang Yan Zhang Jianquan Yao 2021Photonics Research2021,9,4:3
7Heavy soil drying during mid-to-late grain filling stage of the main crop to reduce yield loss of the ratoon crop in a mechanized rice ratooning system显示文摘Yield loss(Y_(Loss)) in the ratoon crop due to crushing damage to left stubble from mechanical harvesting of the main crop is a constraint for wide adoption of mechanized rice ratooning technology.Soil drying before the harvest of the main crop has been proposed to overcome this problem.The objective of this study was to determine the effect of soil drying during the mid-to-late grain filling stage of the main crop on grain yield of the ratoon crop in a mechanized rice ratooning system.Field experiments were conducted to compare Y_(Loss) between light(LD) and heavy(HD) soil drying treatments in Hubei province,central China in 2017 and 2018.Y_(Loss) was calculated as the percentage of yield reduction in the ratoon crop with the main crop harvested mechanically,relative to the grain yield of the ratoon crop with the main crop harvested manually.In comparison with LD,soil hardness was increased by 42.8%-84.7% in HD at the 5-20 cm soil depth at maturity of the main crop.Soil hardness at 5 and 10 cm depths reached respectively 4.05 and 7.07 kg cm^(-2) in HD.Soil drying treatment did not significantly affect the grain yield of the main crop.Under mechanical harvesting of the main crop,HD increased the grain yield of the ratoon crop by 9.4% relative to LD.Consequently,Y_(Loss) was only 3.4% in HD,in contrast to 16.3% in LD.The differences in grain yield and Y_(Loos) between the two soil drying treatments were explained mainly by panicles m^(-2),which was increased significantly by HD in the track zone of the ratoon crop compared with LD.These results suggest that heavy soil drying practice during the mid-to-late grain filling stage of the main crop is effective for reducing Y_(Loss) of the ratoon crop in a mechanized rice ratooning system.Chang Zheng Yuechao Wang Shen Yuan Sen Xiao Yating Sun Jianliang Huang Shaobing Peng 2022The Crop Journal2022,10,1:3
8IntegrinαEβ7^(+)T cells direct intestinal stem cell fate decisions via adhesion signaling显示文摘Intestinal stem cell(ISC)differentiation is regulated precisely by a niche in the crypt,where lymphocytes may interact with stem and transient amplifying(TA)cells.However,whether and how lymphocyte–stem/TA cell contact affects ISC differentiation is largely unknown.Here,we uncover a novel role of T cell–stem/TA cell contact in ISC fate decisions.We show that intestinal lymphocyte depletion results in skewed ISC differentiation in mice,which can be rescued by T cell transfer.Mechanistically,integrinαEβ7 expressed on T cells binds to E-cadherin on ISCs and TA cells,triggering E-cadherin endocytosis and the consequent Wnt and Notch signaling alterations.BlockingαEβ7−E-cadherin adhesion suppresses Wnt signaling and promotes Notch signaling in ISCs and TA cells,leading to defective ISC differentiation.Thus,αEβ7^(+)T cells regulate ISC differentiation at single-cell level through cell–cell contact-mediatedαEβ7−E-cadherin adhesion signaling,highlighting a critical role of the T cell–stem/TA cell contact in maintaining intestinal homeostasis.Shiyang Chen Yajuan Zheng Xiaojuan Ran Hui Du Hua Feng Lei Yang Yating Wen Changdong Lin Shihui Wang Mengwen Huang Zhanjun Yan Dianqing Wu Hongyan Wang Gaoxiang Ge An Zeng Yi Arial Zeng Jianfeng Chen 2021Cell Research2021,31,12:3
9Lightweight 3D bioprinting with point by point photocuring显示文摘As photocrosslinkable materials,methacryloyl-modified hydrogels are widely used as bioinks in tissue engineering.Existing printing methods to use these hydrogels,including changing the viscosity of the material or mixing them with other printing components,have been explored,but their application has been limited due to low printing quality or high cost.In addition,the complex operation of bulky equipment restricts the application of these existing printing methods.This study presents a lightweight stereolithography-based three-dimensional(3D)bioprinting system with a smart mechanical and structural design.The developed bioprinter dimensions were 300 mm×300 mm×200 mm and it can be placed on a benchtop.The equipment has a mini bioink chamber to store a small amount of bioink for each printing.We systematically investigated the point-by-point curing process in the 3D bioprinting method,which can print mixed cells accurately and have good biocompatibility.Here,we provide a compact,low-cost stereolithography bioprinting system with excellent biocompatibility for 3D bioprinting with methacryloyl-modified hydrogels.It can be potentially used for drug screening,studying pathological mechanisms,and constructing biological disease models.Peng Zhang Haoxuan Wang Peng Wang Yating Zheng Linxiang Liu Jun Hu Yande Liu Qing Gao Yong He 2021Bioactive Materials2021,6,5:2
10The mechanisms of melanogenesis inhibition by glabridin:molecular docking,PKA/MITF and MAPK/MITF pathways显示文摘Glabridin is the main ingredient of hydrophobic fraction in licorice extract and has been shown to have anti-melanogenesis activity in skins.However,the underlying mechanism(s)remain not completely understood.The aim of this study is thus to elucidate the possible mechanisms related to the melanogenesis suppression by glabridin in cultured B16 murine melanoma cells and in UVA radiation induced hyperpigmentation model of BALB/c mice as well.Molecular docking simulations revealed that between catalytic core residues and the compound.The treatment by glabridin significantly downregulated both transcriptional and/or protein expression of melanogenesis-related factors including melanocyte stimulating hormone receptor(MC1R),microphthalmia-associated transcription factor(MITF),tyrosinase(TYR),TYR-related protein-1(TRP-1)and TRP-2 in B16 cells.Both PKA/MITF and MAPK/MITF signaling pathways were found to be involved in the suppression of melanogenesis by glabridin in B16 cells.Also in vivo glabridin therapy significantly reduced hyperpigmentation,epidermal thickening,roughness and inflammation induced by frequent UVA exposure in mice skins,thus beneficial for skin healthcare.These data further look insights into the molecular mechanisms of melanogenesis suppression by glabridin,rationalizing the application of the natural compound for skin healthcare.Chunxing Pan Xiaoying Liu Yating Zheng Zejun Zhang Yongliang Li Biao Che Guangrong Liu Lanyue Zhang Changzhi Dong Haji Akber Aisa Zhiyun Du Zhengqiang Yuan 2023Food Science and Human Wellness2023,12,1:2
11State-feedback set stabilization of logical control networks with state-dependent delay显示文摘Dear editor,As an important mathematical model for the elucidation,analysis, and control of gene regulatory networks(GRNs),logical networks have attracted considerable attention from scientists in numerous fields of study. From a mathematical point of view, a logical network is parameter-free;thus, it can be utilized to reconstruct relatively large-scale GRNs.In studying logical networks, stabilization is highly critical as it has been widely used in maintaining human health and treating diseases [1, 2].Yating ZHENG Haitao LI Jun-E FENG 2021Science China(Information Sciences)2021,64,6:2

20Network analysis of eight industrial symbiosis systems显示文摘工业共生是一个 eco 工业的公园的精华的特征。把公园划分成不同类型,主要集中于质的判断,并且没能使用度量标准在一个公园的内部结构或功能的特征上进行量的研究的以前的研究。分析一公园结构的属性,从网络分析的度量标准的一个范围被使用了,但是很少研究人员比较了二或用多重度量标准的更多的 symbioses。在这研究,我们使用了二个度量标准(密度和网络度集中化) 比较完全性的度和八个多样却代表性的工业共生网络的依赖。通过二个度量标准的联合,我们把网络划分了成三种类型:强壮的完全性的弱完全性,和二种形式,也就是抛锚承租人互助论和面向平等的互助论。结果证明有完全性的弱度的网络是稀少的并且在节点之中有很少连接;为锚承租人互助论,完全性的度相对高,但是 affiliated members 太依赖于核心成员;并且在有的面向平等的互助论的成员等于角色,与多样、灵活的共生路径。这些结果揭示了一些系统内部结构并且不同结构怎么在一个系统的成员之中影响了材料,精力,和知识的交换,从而提供卓见进可以使动摇的威胁网络。把分析基于这,我们在一个典型中国 eco 工业的公园(山东 Lubei ) 里提供优点的例子和最近的改进工程的有效性。Yan ZHANG Hongmei ZHENG Han SHI Xiangyi YU Gengyuan LIU Meirong SU Yating LI Yingying CHAI 2016Frontiers of Earth Science2016,10,2:1
