| 1 | 前交叉韧带解剖重建理念与方法显示文摘前交叉韧带(Anterior Cruciate Ligament,ACL)解剖重建技术是基于ACL解剖理论发展起来的一项手术技术。ACL解剖重建是根据ACL的解剖特点进行功能重建,恢复ACL原有的尺寸、韧带胶原走行方向和止点位置。解剖重建不仅包括双束和单束重建,而且包括以此理论为基础的ACL重建术后的翻修与加固。本文对ACL的解剖重建技术进行介绍,针对在关节镜下如何观察原ACL的止点位置,测量止点长宽,选择骨道位置,如何利用影像学进行评价进行了详细的阐述和解释,并介绍了该技术目前的临床评价结果。同时,本文对ACL解剖重建和传统'经典'重建方法的区别进行了重点说明与解释,为提高国内医师对ACL解剖重建技术的认识提供参考和帮助。 | 周敬滨 Zachary Working Carola F.van Eck Freddie H.Fu | 2011 | 中国运动医学杂志2011,30,6: | 34 |
| 2 | Non-Maxwellian electron distributions resulting from direct laser acceleration in near-critical plasmas显示文摘The irradiation of few-nm-thick targets by a finite-contrast high-intensity short-pulse laser results in a strong pre-expansion of these targets at the arrival time of the main pulse.The targets decompress to near and lower than critical densities with plasmas extending over few micrometers,i.e.multiple wavelengths.The interaction of the main pulse with such a highly localized but inhomogeneous target leads to the generation of a short channel and further self-focusing of the laser beam.Experiments at the Glass Hybrid OPCPA Scaled Test-bed(GHOST)laser system at University of Texas,Austin using such targets measured non-Maxwellian,peaked electron distribution with large bunch charge and high electron density in the laser propagation direction.These results are reproduced in 2D PIC simulations using the EPOCH code,identifying direct laser acceleration(DLA)[1]as the responsible mechanism.This is the first time that DLA has been observed to produce peaked spectra as opposed to broad,Maxwellian spectra observed in earlier experiments[2].This high-density electrons have potential applications as injector beams for a further wakefield acceleration stage as well as for pump-probe applications. | T.Toncian C.Wang E.McCary A.Meadows A.V.Arefiev J.Blakeney K.Serratto D.Kuk C.Chester R.Roycroft L.Gao H.Fu X.Q.Yan J.Schreiber I.Pomerantz A.Bernstein H.Quevedo G.Dyer T.Ditmire B.M.Hegelich | 2016 | Matter and Radiation at Extremes2016,1,1: | 3 |
| 3 | 中国四川盆地页岩气注水压裂导致断层再活化并诱发MW4.7地震显示文摘本文对中国四川盆地最近观察到的注水诱发地震进行了及时和详细的研究,四川盆地页岩气水力压裂已经开始启动,计划在未来几年里被逐渐开采。包括传染型余震序列模型、震中重定位、13个大地震事件(MW>3.5)的震源机制以及库仑破裂应力数值计算的众多证据表明,在地下2.3~3km深度范围内水力压裂短期(每个井位数月)注水过程诱发了一系列最高矩震级达MW4.7的地震。反之,这些诱发地震的出现也支持了注水诱发断层再活化的假设。本文同时讨论了此地区注水压裂为什么会诱发如此大震级地震的地质原因。由于四川盆地中水力压裂作业正如火如荼,这也将有利于地球科学、天然气公司、管理部门和学术界共同探讨显著的注水诱发地震的地区因素,以确保页岩气注水压裂可以有效进行并安全实施。 | x.l.lei d.j.huang j.r.su g.m.jiang x.l.wang h.wang x.guo h.fu 唐茂云(译) 周红(校) | 2018 | 世界地震译丛2018,49,6: | 2 |
| 4 | Climate warming shifts the time interval between flowering and leaf unfolding depending on the warming period显示文摘The timing of flowering(FL)and leaf unfolding(LU)determine plants’reproduction and vegetative growth.Global warming has substantially advanced FL and LU of temperate and boreal plants,but their responses to warming differ,which may influence the time interval between FL and LU(ΔLU-FL),thereby impacting plant fitness and intraspecific physiological processes.Based on twigs collected from two flowering-first tree species,Populus tomentosa and Amygdalus triloba,we conducted a manipulative experiment to investigate the effects of winter chilling,spring warming and photoperiod on theΔLU-FL.We found that photoperiod did not affect theΔLU-FL of Amygdalus triloba,but shortenedΔLU-FL by 5.1 d of Populus tomentosa.Interestingly,spring warming and winter chilling oppositely affected theΔLU-FL of both species.Specifically,low chilling accumulation extended theΔLU-FL by 3.8 and 9.4 d for Populus tomentosa and Amygdalus triloba,but spring warming shortened theΔLU-FL by 4.1 and 0.2 d℃^(-1).Our results indicate that climate warming will decrease or increase theΔLU-FL depending on the warming periods,i.e.,spring or winter.The shifted time interval between flowering and leaf unfolding may have ecological effects including affecting pollen transfer efficiency and alter the structure and functioning of terrestrial ecosystem. | Shuxin Wang Zhaofei Wu Yufeng Gong Shubiao Wang Wei Zhang Shanshan Zhang Hans J.De Boeck Yongshuo H.Fu | 2022 | Science China(Life Sciences)2022,65,11: | 2 |

| 6 | Vegetation phenology and its ecohydrological implications from individual to global scales显示文摘The Earth is experiencing unprecedented climate change.Vegetation phenology has already showed strong response to the global warming,which alters mass and energy fluxes on terrestrial ecosystems.With technology and method developments in remote sensing,computer science and citizen science,many recent phenology-related studies have been focused on macrophenology.In this perspective,we 1)reviewed the responses of vegetation phenology to climate change and its impacts on carbon cycling,and reported that the effect of shifted phenology on the terrestrial carbon fluxes is substantially different between spring and autumn;2)elaborated how vegetation phenology affects ecohydrological processes at different scales,and further listed the key issues for each scale,i.e.,focusing on seasonal effect,local feedbacks and regional vapor transport for individual,watershed and global respectively);3)envisioned the potentials to improve current hydrological models by coupling vegetation phenology-related processes,in combining with machine learning,deep learning and scale transformation methods.We propose that comprehensive understanding of climate-macrophenology-hydrology interactions are essential and urgently needed for enhancing our understanding of the ecosystem response and its role in hydrological cycle under future climate change. | Shouzhi Chen Yongshuo H.Fu Fanghua Hao Xiaoyan Li Sha Zhou Changming Liu Jing Tang | 2022 | Geography and Sustainability2022,3,4: | 1 |

| 9 | Warming-induced phenological mismatch between trees and shrubs explains high-elevation forest expansion显示文摘Despite the importance of species interaction in modulating the range shifts of plants,little is known about the responses of coexisting life forms to a warmer climate.Here,we combine long-term monitoring of cambial phenology in sympatric trees and shrubs at two treelines of the Tibetan Plateau,with a meta-analysis of ring-width series from 344 shrubs and 575 trees paired across 11 alpine treelines in the Northern Hemisphere.Under a spring warming of+1℃,xylem resumption advances by 2-4 days in trees,but delays by 3-8 days in shrubs.The divergent phenological response to warming was due to shrubs being3.2 times more sensitive than trees to chilling accumulation.Warmer winters increased the thermal requirement for cambial reactivation in shrubs,leading to a delayed response to warmer springs.Our meta-analysis confirmed such a mechanism across continental scales.The warming-induced phenological mismatch may give a competitive advantage to trees over shrubs,which would provide a new explanation for increasing alpine treeline shifts under the context of climate change. | Xiaoxia Li Eryuan Liang JJulio Camarero Sergio Rossi Jingtian Zhang Haifeng Zhu Yongshuo H.Fu Jian Sun Tao Wang Shilong Piao Josep Penuelas | 2023 | National Science Review2023,10,10: | 0 |
| 10 | Contrasting phenology responses to climate warming across the northern extra-tropics显示文摘Climate warming has substantially advanced the timing of spring leaf-out of woody species at middle and high latitudes,albeit with large differences.Insights in the spatial variation of this climate warming response may therefore help to constrain future trends in leaf-out and its impact on energy,water and carbon balances at global scales.In this study,we used in situ phenology observations of 38 species from 2067 study sites,distributed across the northern hemisphere in China,Europe and the United States,to investigate the latitudinal patterns of spring leaf-out and its sensitivity(S T,advance of leaf-out dates per degree of warming)and correlation(R_(T),partial correlation coefficient)to temperature during the period 1980-2016.Across all species and sites,we found that S_(T) decreased significantly by 0.15±0.02 d℃^(-1)°N^(-1),and R_(T) increased by 0.02±0.001°N^(-1)(both at P<0.001).The latitudinal patterns in R_(T) and S_(T) were explained by the differences in requirements of chilling and thermal forcing that evolved to maximize tree fitness under local climate,particularly climate predictability and summed precipitation during the pre-leaf-out season.Our results thus showed complicated spatial differences in leaf-out responses to ongoing climate warming and indicated that spatial differences in the interactions among environmental cues need to be embedded into large-scale phenology models to improve the simulation accuracy. | Xiaojun Geng Yaru Zhang Yongshuo H.Fu Fanghua Hao Ivan A.Janssens Josep Penuelas Shilong Piao Jing Tang Zhaofei Wu Jing Zhang Xuan Zhang Nils Chr.Stenseth | 2022 | Fundamental Research2022,2,5: | 0 |
| 11 | Evidence of advancing spring xylem phenology in Chinese forests under global warming显示文摘Phenological responses of vegetation to the ongoing warming trend impact current and future primary productivity.However,few studies focus on wood phenology because its observed data are much scarcer,which hinders the estimation and prediction of forest carbon budgets over large regions.Here,we use a physiological process-based tree-ring growth model(Vaganov-Shashkin model)to investigate the spatial and temporal variations of spring xylem phenology(start of the growing season of xylem,SOS_(x))in tree-ring sites of China during 1962-2016 CE.The model is calibrated on measured tree-ring width chronologies(70 tree-ring chronologies)and successfully validated with field observations of xylogenesis.We found that spring xylem phenology significantly advances during 1962-2016 CE period under global warming,with the rate of advance quickly increasing after the 1990s to an average of 0.25 days per year.The preseason daily mean temperature is the main climatic driver for spring xylem phenology as indicated by its significant correlations with SOS_(x)at most sites(71%).Warmer preseason allows heat requirements for tree growth to be reached more quickly,with increase of 1℃in temperature of preseason anticipates SOS_(x)by 6 to 7 days,which will benefit the radial growth of trees in the relatively cold-humid environments.In addition,the significant positive correlation between the simulated spring xylem phenology and remote sensing derived phenology highlights the primary and secondary growth may be governed by the same variable(temperature)and change in the same direction with global warming.This study provides the long-term perspective on the spring xylem phenology variations covering most of China. | Huihong XUE Feng SHI Fabio GENNARETTI Yongshuo H.FU Bin HE Xiuchen WU Zhengtang GUO | 2023 | Science China Earth Sciences2023,66,10: | 0 |
