| 3 | Intelligent control of mode-locked femtosecond pulses by time-stretch-assisted real-time spectral analysis显示文摘Mode-locked fiber lasers based on nonlinear polarization evolution can generate femtosecond pulses with different pulse widths and rich spectral distributions for versatile applications through polarization tuning.However,a precise and repeatable location of a specific pulsation regime is extremely challenging.Here,by using fast spectral analysis based on a time-stretched dispersion Fourier transform as the spectral discrimination criterion,along with an intelligent polarization search algorithm,for the first time,we achieved real-time control of the spectral width and shape of mode-locked femtosecond pulses;the spectral width can be tuned from 10 to 40 nm with a resolution of ~1.47 nm,and the spectral shape can be programmed to be hyperbolic secant or triangular.Furthermore,we reveal the complex,repeatable transition dynamics of the spectrum broadening of femtosecond pulses,including five middle phases,which provides deep insight into ultrashort pulse formation that cannot be observed with traditional mode-locked lasers. | Guoqing Pu Lilin Yi Li Zhang Chao Luo Zhaohui Li Weisheng Hu | 2020 | Light(Science & Applications)2020，9，1： | 16 |
| 4 | Spin-decoupled metasurface for simultaneous detection of spin and orbital angular momenta via momentum transformation显示文摘With inherent orthogonality,both the spin angular momentum(SAM)and orbital angular momentum(OAM)of photons have been utilized to expand the dimensions of quantum information,optical communications,and information processing,wherein simultaneous detection of SAMs and OAMs with a single element and a single-shot measurement is highly anticipated.Here,a single azimuthal-quadratic phase metasurface-based photonic momentum transformation(PMT)is illustrated and utilized for vortex recognition.Since different vortices are converted into focusing patterns with distinct azimuthal coordinates on a transverse plane through PMT,OAMs within a large mode space can be determined through a single-shot measurement.Moreover,spin-controlled dual-functional PMTs are proposed for simultaneous SAM and OAM sorting,which is implemented by a single spin-decoupled metasurface that merges both the geometric phase and dynamic phase.Interestingly,our proposed method can detect vectorial vortices with both phase and polarization singularities,as well as superimposed vortices with a certain interval step.Experimental results obtained at several wavelengths in the visible band exhibit good agreement with the numerical modeling.With the merits of ultracompact device size,simple optical configuration,and prominent vortex recognition ability,our approach may underpin the development of integrated and high-dimensional optical and quantum systems. | Yinghui Guo Shicong Zhang Mingbo Pu Qiong He Jinjin Jin Mingfeng Xu Yaxin Zhang Ping Gao Xiangang Luo | 2021 | Light(Science & Applications)2021，10，4： | 14 |
| 5 | Comorbidity Burden of Dementia:A Hospital-Based Retrospective Study from 2003 to 2012 in Seven Cities in China显示文摘Dementia is increasing dramatically and imposes a huge burden on society. To date, there is a lack of data on the health status of patients with dementia in China. In an attempt to investigate the comorbidity burden of dementia patients in China at the national level, we enrolled 2,938 patients with Alzheimer's disease(AD), vascular dementia(Va D), or other types of dementia, who were admitted to tertiary hospitals in seven regions of China from January2003 to December 2012. The Charlson Comorbidity Index(CCI) was used to evaluate the comorbidity burden of the patients with dementia. Among these patients, 53.4% had AD, 26.3% had Va D, and 20.3% had other types of dementia. The CCI was 3.0 ± 1.9 for all patients,3.4 ± 1.8 for those with Va D, and 3.0 ± 2.1 for those with AD. The CCI increased with age in all patients, andthe length of hospital stay and daily expenses rose with age and CCI. Males had a higher CCI and a longer stay than females. Moreover, patients admitted in the last 5 years of the study had a higher CCI than those admitted in the first 5 years. We found that the comorbidity burden of patients with dementia is heavy. These findings provide a better understanding of the overall health status of dementia patients, and help to increase the awareness of clinicians and policy-makers to improve medical care for patients. | Qing-Hua Wang Xin Wang Xian-Le Bu Yan Lian Yang Xiang Hong-Bo Luo Hai-Qiang Zou Jie Pu Zhong-He Zhou Xiao-Ping Cui Qing-Song Wang Xiang-Qun Shi Wei Han Qiang Wu Hui-Sheng Chen Hang Lin Chang-Yue Gao Li-Li Zhang Zhi-Qiang Xu Meng Zhang Hua-Dong Zhou Yan-Jiang Wang | 2017 | Neuroscience Bulletin2017，33，6： | 10 |
| 6 | Modified graphene as novel lubricating additive with high dispersion stability in oil显示文摘Graphene is a promising material as a lubricant additive for reducing friction and wear.Here,a dispersing method which combines chemical modification of graphene by octadecylamine and dicyclohexylcarbodiimide with a kind of effective dispersant has been successfully developed to achieve the remarkable dispersion stability of graphene in base oil.The stable dispersion time of modified graphene(0.5 wt%)with dispersant(1 wt%)in PAO-6 could be up to about 120 days,which was the longest time reported so far.At the same time,the lubricant exhibits a significant improvement of tribological performance for a steel ball to plate tribo-system with a normal load of 2 N.The coefficient of friction between sliding surfaces was~0.10 and the depth of wear track on plate was~21 nm,which decreased by about 44%and 90%when compared to pure PAO-6,respectively.Furthermore,the analysis of the lubricating mechanisms in regard to the sliding-induced formation of nanostructured tribo-film has been contacted by using Raman spectra and TEM. | Pu WU Xinchun CHEN Chenhui ZHANG Jiping ZHANG Jianbin LUO Jiyang ZHANG | 2021 | Friction2021，9，1： | 9 |
| 7 | Fisetin mitigates hepatic ischemia-reperfusion injury by regulating GSK3β/AMPK/NLRP3 inflammasome pathway显示文摘Background: Hepatic ischemia-reperfusion(I/R) injury(IRI) represents a crucial challenge in liver transplantation. Fisetin has anti-inflammatory, anti-aging and anti-oxidative properties. This study aimed to examine whether fisetin mitigates hepatic IRI and examine its underlying mechanisms. Methods: Sham or warm hepatic I/R operated mice were pretreated with fisetin(5, 10 or 20 mg/kg). Hepatic histological assessments, TUNEL assays and serum aminotransferase measurements were performed. An in vitro hypoxia/reoxygenation(H/R) model using RAW264.7 macrophages pretreated with fisetin(2.5, 5 or 10 μmol/L) was also used. Serum and cell supernatant concentrations of interleukin-1 β(IL-1 β), IL-18 and tumor necrosis factor-α(TNF-α) were determined by enzyme-linked immunosorbent assay(ELISA). Protein levels of p-GSK3 β, p-AMPK and NLR family pyrin domain-containing 3(NLRP3)-associated proteins were detected by Western blotting. Results: Compared with the I/R group, fisetin pretreatment reduced pathological liver damage, serum aminotransferase levels, serum concentrations of IL-1 β, IL-18 and TNF-α in the murine IRI model. Fisetin also reduced the expression of NLRP3 inflammasome-associated proteins(NLRP3, cleaved caspase-1, IL-1 β and IL-18) in I/R-operated liver. The experiments in vitro showed that fisetin decreased the release of IL-1 β, IL-18 and TNF-α, and reduced the expression of NLRP3 inflammasome-associated proteins in H/R-treated RAW264.7 cells. Moreover, fisetin increased the expressions of p-GSK3 β and p-AMPK in both models, indicating that its anti-inflammatory effects were dependent on GSK3 β/AMPK signaling. The antiinflammatory effects of fisetin were partially inhibited by the AMPK specific inhibitor compound C. Conclusions: Fisetin showed protective effects against hepatic IRI, countering inflammatory responses through mediating the GSK3 β/AMPK/NLRP3 inflammasome pathway. | Jun-Liang Pu Zuo-Tian Huang Yun-Hai Luo Tong Mou Ting-Ting Li Zhong-Tang Li Xu-Fu Wei Zhong-Jun Wu | 2021 | Hepatobiliary & Pancreatic Diseases International2021，20，4： | 9 |
| 8 | Broadband spin Hall effect of light in single nanoapertures显示文摘With properties not previously available,optical metamaterials and metasurfaces have shown their great potential in the precise control of light waves at the nanoscale.However,the use of current metamaterials and metasurfaces is limited by the collective response of the meta-atoms/molecules,which means that a single element cannot provide the functionalities required by most applications.Here,we demonstrate for the first time that a single achiral nanoaperture can be utilized as a meta-macromolecule to achieve giant angular spin Hall effect of light.By controlling the spin-related momenta,we show that these nanoapertures can enable full control of the phase gradient at a deep-subwavelength level,thus forming unique building blocks for optical metasurfaces.As a proof-of-concept demonstration,a miniaturized Bessel-like beam generator and flat lens are designed and experimentally characterized.The results presented here may open a door for the development of meta-macromolecule-based metasurfaces for integrated optical systems and nanophotonics. | Xian-Gang Luo Ming-Bo Pu Xiong Li Xiao-Liang Ma | 2017 | Light(Science & Applications)2017，6，1： | 9 |

| 10 | Spatial Pattern Evolution and Casual Analysis of County Level Economy in Changsha-Zhuzhou-Xiangtan Urban Agglomeration, China显示文摘In order to evaluate whether or not the county units′ economy in the Changsha-Zhuzhou-Xiangtan(Chang-Zhu-Tan) Urban Agglomeration was growing as expected, this study analyzed the spatial economy pattern at county-level by using the Exploratory Spatial Data Analysis(ESDA) method. In this process, the global Moran′s I and local Getis-Ord G*i indexes were employed to analyze indicators including per capita GDP and three industrials(i.e. primary, secondary and tertiary industry) from 2000 to 2010. The results show that: 1) the county units′ economy in the Chang-Zhu-Tan Urban Agglomeration has exhibited a strong spatial autocorrelation and an accelerated integration trend since 2008(Moran′ s I increased from 0.26 to 0.56); 2) there is a significant difference in economy development between the northern and southern county units in the Chang-Zhu-Tan Urban Agglomeration: the hotspot zone with high economic level was formed among the northern county units whereas the coldspot zone with low economic level was located in the southern areas. This difference was caused primarily by the increasingly prominent economic radiation effect of Changsha ′upheaval′; 3) town density, secondary industry, and the integration policy are the major contributors driving the evolution of the spatial economy pattern in the Chang-Zhu-Tan Urban Agglomeration. | DONG Minghui ZOU Bin PU Qiang WAN Neng YANG Lingbin LUO Yanqing | 2014 | Chinese Geographical Science2014，24，5： | 8 |
| 11 | Symmetry breaking of photonic spin-orbit interactions in metasurfaces显示文摘Spin-orbit optical phenomena pertain to the wider class of electromagnetic effects originating from the interaction of the photon spin with the spatial structure and propagation characteristics of an optical wave,mediated by suitable optical media.There are many emerging photonic applications of spin-orbit interactions(SOI)of light,such as control of the optical wave propagation via the spin,enhanced optical manipulation,and generation of structured optical fields.Unfortunately,current applications are based on symmetric SOI,that is,the behaviours of polarized photons with two opposite spins are opposite,leading to the limit of spin-based multiplexers.The symmetry of SOI can be broken in our proposed metasurfaces,consisting of spatially varying birefringence,which can arbitrarily and independently build SOI for two opposite spins without reduction of optical energy usage.We obtain three kinds of dual-functional metasurfaces at visible and infrared wavelengths with high efficiency.Our concept of generation of asymmetric SOI for two spins,using anisotropic metasurfaces,will open new degrees of freedoms for building new types of spin-controlled multifunctional shared-aperture devices for the generation of complex structured optical fields. | Fei Zhang Mingbo Pu Jun Luo Honglin Yu Xiangang Luo | 2017 | 光电工程2017，44，3： | 8 |
| 12 | Off-axis multi-wavelength dispersion controllingmetalens for multi-color imaging显示文摘Dispersion control is crucial in optical systems,and chromatic aberration is an important factor affecting imaging quality in imaging systems.Due to the inherent property of materials,dispersion engineering is complex and needs to trade off other aberration in traditional ways.Although metasurface offers an effective method to overcome these limits and results in well-engineered dispersion,off-axis dispersion control is still a challenging topic.In this paper,we design a single-layer metalens which is capable of focusing at three wavelengths(473 nm,532 nm,and 632 nm)with different incident angles(0°,-17°and 17°)into the same point.We also demonstrate that this metalens can provide an alternative for the bulky color synthetic prism in a 3-chips digital micromirror device(DMD)laser projection system.Through this approach,various off-axis dispersion controlling optical devices could be realized. | Kaihua Dou Xin Xie Mingbo Pu Xiong Li Xiaoliang Ma Changtao Wang Xiangang Luo | 2020 | Opto-Electronic Advances2020，3，4： | 7 |
| 13 | Protonation induced high-T_c phases in iron-based superconductors evidenced by NMR and magnetization measurements显示文摘Chemical substitution during growth is a well-established method to manipulate electronic states of quantum materials, and leads to rich spectra of phase diagrams in cuprate and iron-based superconductors. Here we report a novel and generic strategy to achieve nonvolatile electron doping in series of(i.e.11 and 122 structures) Fe-based superconductors by ionic liquid gating induced protonation at room temperature. Accumulation of protons in bulk compounds induces superconductivity in the parent compounds, and enhances the Tclargely in some superconducting ones. Furthermore, the existence of proton in the lattice enables the first proton nuclear magnetic resonance(NMR) study to probe directly superconductivity. Using Fe S as a model system, our NMR study reveals an emergent high-Tcphase with no coherence peak which is hard to measure by NMR with other isotopes. This novel electric-fieldinduced proton evolution opens up an avenue for manipulation of competing electronic states(e.g.Mott insulators), and may provide an innovative way for a broad perspective of NMR measurements with greatly enhanced detecting resolution. | Yi Cui Gehui Zhang Haobo Li Hai Lin Xiyu Zhu Hai-Hu Wen Guoqing Wang Jinzhao Sun Mingwei Ma Yuan Li Dongliang Gong Tao Xie Yanhong Gu Shiliang Lie Huiqian Luo Pu Yu Weiqiang Yu | 2018 | Science Bulletin2018，63，1： | 7 |
| 14 | Crosstalk-free achromatic full Stokes imaging polarimetry metasurface enabled by polarization-dependent phase optimization显示文摘Imaging polarimetry is one of the most widely used analytical technologies for object detection and analysis.To date,most metasurface-based polarimetry techniques are severely limited by narrow operating bandwidths and inevitable crosstalk,leading to detrimental effects on imaging quality and measurement accuracy.Here,we propose a crosstalkfree broadband achromatic full Stokes imaging polarimeter consisting of polarization-sensitive dielectric metalenses,implemented by the principle of polarization-dependent phase optimization.Compared with the single-polarization optimization method,the average crosstalk has been reduced over three times under incident light with arbitrary polarization ranging from 9μm to 12μm,which guarantees the measurement of the polarization state more precisely.The experimental results indicate that the designed polarization-sensitive metalenses can effectively eliminate the chromatic aberration with polarization selectivity and negligible crosstalk.The measured average relative errors are 7.08%,8.62%,7.15%,and 7.59%at 9.3,9.6,10.3,and 10.6μm,respectively.Simultaneously,the broadband full polarization imaging capability of the device is also verified.This work is expected to have potential applications in wavefront detection,remote sensing,light-field imaging,and so forth. | Yaxin Zhang Mingbo Pu Jinjin Jin Xinjian Lu Yinghui Guo Jixiang Cai Fei Zhang Yingli Ha Qiong He Mingfeng Xu Xiong Li Xiaoliang Ma Xiangang Luo | 2022 | Opto-Electronic Advances2022，5，11： | 6 |

| 17 | Effects of clonal integration and nitrogen supply on responses of a clonal plant to short-term herbivory显示文摘Aims Clonal integration,i.e.resource sharing between interconnected ramets,can help clonal plants tolerate abiotic stress.However,few studies have directly examined the ecological significance of clonal integration in the ability of clonal plants to tolerate biotic stress such as herbivory.Methods We grew clonal fragments of an invasive clonal plant Alternanthera philoxeroides,each consisting of an apical part(relatively young)and a basal part(relatively old),at two levels(low and high)of soil nitrogen(N).For each fragment,the apical part was subjected to either no herbivory or herbivory for 2 weeks by a specialist insect,Agasicles hygrophila,and was either connected with or discon-nected from the basal part not subjected to herbivory.Important Findings Herbivory in the apical part severely reduced leaf growth(leaf mass,leaf number or leaf area)and ramet production of both apical and basal parts,and increased root to shoot ratio of the apical part.Irrespective of herbivory and soil N,stem connection between the apical and the basal part decreased root to shoot ratio of the ap-ical part,but did not change its growth measures.Meanwhile,con-nection increased stem N concentration of the apical part growing under high-N supply and decreased stem carbon(C)concentration of the apical part under low-N supply.By contrast,connection in-creased root to shoot ratio of the basal part,but reduced its leaf and ramet production.Connection also increased leaf and stem C concentrations of the basal part under low-N supply.Thus,clonal integration can be beneficial for the early development of young A.philoxeroides ramets,but not for their local adaptation to herbivory damage by A.hygrophila. | Bi-Cheng Dong Li-Min Zhang Kai-Yu Li Xiao-Ting Hu Pu Wang Yong-Jian Wang Fang-Li Luo Hong-Li Li Fei-Hai Yu | 2019 | Journal of Plant Ecology2019，12，4： | 6 |
| 18 | All‐metallic wide‐angle metasurfaces for multifunctional polarization manipulation显示文摘Optical camouflage is a magical capability of animals as first noticed in 1794 by Erasmus Darwin in Zoonomia,but current biomimetic camouflage strategies cannot be readily applied in complex environments involving multispectral and in particular multi-polarization detection.Here we develop a plasmonic approach toward broadband infrared polarimetric crypsis,where the polarized thermal emission near the pseudo-Brewster angle is the main signal source and no existing polarizing camouflage technique has been discovered in nature.Based on all-metallic subwavelength structures,an electrodynamic resistance-reduction mechanism is proposed to avoid the significant polarization-dependent infrared absorption/radiation.It is also found that the structured metal surface presents giant extrinsic anisotropy regarding the phase shift between orthogonal polarization states,which helps to realize ultrahigh-efficiency and tunable polarization conversion in an unprecedented manner.Finally,we note that the catenary optical theory may provide a useful means to explain and predict these unusual performances. | Xiaoliang Ma Mingbo Pu Xiong Li Yinghui Guo Xiangang Luo | 2019 | Opto-Electronic Advances2019，2，3： | 6 |
| 19 | Boosting proso millet yield by altering canopy light distribution in proso millet/mung bean intercropping systems显示文摘To elucidate the mechanism by which intercropping proso millet(Panicum miliaceum L.)with mung bean(Vigna radiata L.)increases proso millet yield and to determine how this higher yield results from maximization of resources use efficiency,we designed and conducted four strip intercropping row arrangements,including two rows of proso millet alternating with two rows of mung bean(2P2M),four rows of proso millet alternating with two rows of mung bean(4P2M),four rows of proso millet alternating with four rows of mung bean(4P4M),two rows of proso millet alternating with four rows of mung bean(2P4M),sole proso millet(SP,control)and sole mung bean(SM,control)in Yulin,Shaanxi,China.Photosynthetically active radiation(PAR)in the canopy,radiation use efficiency(RUE),leaf photosynthetic characteristics,dry matter accumulation and allocation,and yield of proso millet were investigated.The results showed that the intercropping systems had higher PAR than the monoculture.Mean PAR intensities were increased by respectively 2.2%–23.4%,19.8%–59.7%,and 61.2%–133.3%in the proso millet upper,middle and lower canopies compared with SP.The increase in PAR directly increased RUE,a result attributed mainly to the increase in photosynthetic capacity,including net photosynthetic rate and chlorophyll content.These responses resulted in increased dry matter allocation to plant organs.Yield of intercropped proso millet was 6.8%–37.3%higher than that under monoculture and the land equivalent ratios for the different intercropping patterns were all greater than unity(>1).In general,yield followed a positive linear function of PAR in the intercropping system.The results indicated that intercropping can boost proso millet yield,evidently by altering light distribution within its canopy and consequently increasing RUE,thereby increasing leaf photosynthetic capacity,dry matter accumulation,and allocation to the grain.The optimum combination for improving the growth and yield of proso millet on the Loess Plateau of China was 2P4M. | Xiangwei Gong Uzizerimana Ferdinand Ke Dang Jing Li Guanghua Chen Yan Luo Pu Yang Baili Feng | 2020 | The Crop Journal2020，8，2： | 6 |
| 20 | Progress and Strategies in Cross Breeding of Poplars in China显示文摘The advance in intrasection and intersection cross breeding of poplars in China over the past 50 years is reviewed. Great progress has been made in Sections Leuce and Aigeiros, and satisfactory results of intersection hybridization have been achieved in the crossing between Sections Tacamahaca and Aigeiros. The modes of hybridization include single cross, double cross, triple cross, backcross, etc. It is known that using hybrids as parents to cross with other species or hybrids is an effective and easy way to obtain heterosis. Fast growth, cold and drought tolerance, pest and disease resistance, narrow crowns and rootage, etc. are breeding goals. The conventional artificial crossing is still a major breeding method, and a combination of the conventional artificial crossing with physical radiation and chemical induction can create new triploid individuals that possess higher yield potential. The super clones cultivated have already displayed enormous socioeconomic and ecological benefits in practice. Finally, the problems that investigators have to face at present are discussed as well as some strategies in poplar cross breeding in China. | Li Shan-wen Zhang Zhi-yi Luo Jun-min He Cheng-zhong Pu Ying-shan An Xin-min | 2005 | Forestry Studies in China2005，7，3： | 6 |
