1利用生态痕迹评价自然资本的利用在瑞典及亚区的应用显示文摘利用生态痕迹(ecological pootprint)评价人类对自然资本的利用,就是将资源消耗和废弃物产生与地球的再生能力进行比较。以前基于联合国统计资料的研究已经表明,人类对自然资本的利用已经超过了全球的生物承载力(biocapacity),同时还表明人类的生态痕迹有着很大的分布尺度。本研究主要针对瑞典,我们改进了生态痕迹与生物承裁力的计算方法,并且说明了如何才能将一个国家的生态痕迹应用于区域甚至流域。本研究还首次包含了农田淋溶的植物养分吸收区和家庭用水供应区。本文描述了生态痕迹这一评价方法,与别人和我们自己以前所使用的方法进行了对比,并讨论了这一方法应用的可能性和局限性。Mathis Wackernagel Lillemor Lewan Carina Borgstrom Hansson 闵庆文 1999AMBIO-人类环境杂志1999,28,7:160

4心房颤动——当今面临的挑战显示文摘在过去数年里,临床和科撞方面对心房颤动(房颤)的关注明显增加,有关这一论题的出版物数量迅速、稳定的增长就是证明。虽然已有一些新方法治疗遮一心律失常一但大多数房颤患者仍然不得不忍受这一心律失常,包括其不良后果和症状,房颤无疑是虽迫切需要有更好治疗方法的一种心律失常。为了达到这一目的,就需要更深刻地认识房颤的机制.以便开发直接影响这一基础病理生理机制的治疗措施。Olsson SB Hansson A Hedin E Holm M Ingemansson M Johansson R Meurling C Pehrson S Roijer A Yuan S 方丕华 1997中华心律失常学杂志1997,1,1:3
5Optical force-induced nonlinearity and self-guiding of light in human red blood cell suspensions显示文摘Osmotic conditions play an important role in the cell properties of human red blood cells(RBCs),which are crucial for the pathological analysis of some blood diseases such as malaria.Over the past decades,numerous efforts have mainly focused on the study of the RBC biomechanical properties that arise from the unique deformability of erythrocytes.Here,we demonstrate nonlinear optical effects from human RBCs suspended in different osmotic solutions.Specifically,we observe self-trapping and scattering-resistant nonlinear propagation of a laser beam through RBC suspensions under all three osmotic conditions,where the strength of the optical nonlinearity increases with osmotic pressure on the cells.This tunable nonlinearity is attributed to optical forces,particularly the forward-scattering and gradient forces.Interestingly,in aged blood samples(with lysed cells),a notably different nonlinear behavior is observed due to the presence of free hemoglobin.We use a theoretical model with an optical force-mediated nonlocal nonlinearity to explain the experimental observations.Our work on light self-guiding through scattering biosoft-matter may introduce new photonic tools for noninvasive biomedical imaging and medical diagnosis.Rekha Gautam Yinxiao Xiang Josh Lamstein Yi Liang Anna Bezryadina Guo Liang Tobias Hansson Benjamin Wetzel Daryl Preece Adam White Matthew Silverman Susan Kazarian Jingjun Xu Roberto Morandotti Zhigang Chen 2019Light(Science & Applications)2019,8,1:3
6Stable femtosecond X-rays with tunable polarization from a laser-driven accelerator显示文摘Technology based on high-peak-power lasers has the potential to provide compact and intense radiation sources for a wide range of innovative applications.In particular,electrons that are accelerated in the wakefield of an intense laser pulse oscillate around the propagation axis and emit X-rays.This betatron source,which essentially reproduces the principle of a synchrotron at the millimeter scale,provides bright radiation with femtosecond duration and high spatial coherence.However,despite its unique features,the usability of the betatron source has been constrained by its poor control and stability.In this article,we demonstrate the reliable production of X-ray beams with tunable polarization.Using ionization-induced injection in a gas mixture,the orbits of the relativistic electrons emitting the radiation are reproducible and controlled.We observe that both the signal and beam profile fluctuations are significantly reduced and that the beam pointing varies by less than a tenth of the beam divergence.The polarization ratio reaches 80%,and the polarization axis can easily be rotated.We anticipate a broad impact of the source,as its unprecedented performance opens the way for new applications.Andreas Döpp Benoit Mahieu Agustin Lifschitz Cedric Thaury Antoine Doche Emilien Guillaume Gabriele Grittani Olle Lundh Martin Hansson Julien Gautier Michaela Kozlova Jean Philippe Goddet Pascal Rousseau Amar Tafzi Victor Malka Antoine Rousse Sebastien Corde Kim Ta Phuoc 2017Light(Science & Applications)2017,6,1:2

10斯堪的纳维亚半岛地方性和区域性大气颗粒污染对健康影响的比较评价显示文摘正在实施的'欧洲清洁空气计划'(CAFE)是欧盟委员会(TheEU Commission)的一个倡议,其目的是开展一项旨在改善欧盟空气质量的协调一致的行动。该项目关注的焦点是已经证明对人类健康有着巨大影响的颗粒物质。CAFE要求世界卫生组织(WHO)作了一份关于大气污染物和人类健康关系的最新研究进展的综述,以便在此基础上进行不同大气污染物及其对人类健康影响的评估。WHO所作的关于欧洲空气污染物对健康影响方面的综述证实,即使是较低颗粒物水平,也会对人类健康构成明显的威胁。在瑞典人口中,使用推荐的统一风险系数对颗粒物质影响的评估表明,不考虑污染源,与远程传输的人为造成的颗粒物有关的过早死亡人数,估计大概每年有3500人;相应地预期寿命减少大约7个月。当考虑地方性污染源,把现有的风险系数和暴露数据联系起来时,由于存在大量不确定因素,对地方性污染源影响的估计显得更加困难,但是估计值表明,每年大约有1800人过早死亡,他们的平均寿命大约减少了2~3个月。然而,暴露在局部污染严重、高污染物浓度下的一部分人口, 其预期寿命可能遭受更大幅度的减少。越来越多的文献资料支持燃烧形成的颗粒物具有更高相对风险的假设,因而,进一步的研究可能会转移污染控制战略的重点。CAFE项目建立了一个全面高效的降低大气颗粒物策略。根据对背景暴露值的研究,我们的结果表明,在瑞典,远程传输富含硫酸盐的颗粒是造成颗粒物质健康影响的主导因素。在整个斯堪的纳维亚半岛和很多受到越界空气污染影响的国家都会发现相同的研究结果。然而,一些包括采用高空间分辨率方法的流行病学等健康研究都表明,机动车尾气颗粒比其它颗粒物对健康更具危害性。这些互相矛盾的研究成果必须被理解,同时,应由专家给出特定污染源对人类健康影响的估算,否则不可能在欧洲找到全面高效降低大气污染性物质最有效的解决方案。我们不应满足于目前的研究结果,即认为每一种降低颗粒物浓度的措施对单位物质浓度的变化具有相同的作用。显然,我们非常需要引进更有针对性的暴露变量、更高地理分辨率的流行病学方法和健康影响效应评估。Bertil Forsberg Hans-Christen Hansson Christer Johansson Hans Areskoug Karin Persson Bengt Jrvholm 王丽荣 2005AMBIO-人类环境杂志2005,34,1:2

14A review of modern treeline migration, the factors controlling it and the implications for carbon storage显示文摘Numerous studies have reported that treelines are moving to higher elevations and higher latitudes.Most treelines are temperature limited and warmer climate expands the area in which trees are capable of growing.Hence,climate change has been assumed to be the main driver behind this treeline movement.The latest review of treeline studies was published in 2009 by Harsch et al.Since then,a plethora of papers have been published studying local treeline migration.Here we bring together this knowledge through a review of 142 treeline related publications,including 477 study locations.We summarize the information known about factors limiting tree-growth at and near treelines.Treeline migration is not only dependent on favorable growing conditions but also requires seedling establishment and survival above the current treeline.These conditions appear to have become favorable at many locations,particularly so in recent years.The review revealed that at 66%of these treeline sites forest cover had increased in elevational or latitudinal extent.The physical form of treelines influences how likely they are to migrate and can be used as an indicator when predicting future treeline movements.Our analysis also revealed that while a greater percentage of elevational treelines are moving,the latitudinal treelines are capable of moving at greater horizontal speed.This can potentially have substantial impacts on ecosystem carbon storage.To conclude the review,we present the three main hypotheses as to whether ecosystem carbon budgets will be reduced,increased or remain the same due to treeline migration.While the answer still remains under debate,we believe that all three hypotheses are likely to apply depending on the encroached ecosystem.Concerningly,evidence is emerging on how treeline migration may turn tundra landscapes from net sinks to net sources of carbon dioxide in the future.HANSSON Amanda DARGUSCH Paul SHULMEISTER Jamie 2021Journal of Mountain Science2021,18,2:2
