1Converting lateral scanning into axial focusing to speed up three-dimensional microscopy显示文摘In optical microscopy,the slow axial scanning rate of the objective or the sample has traditionally limited the speed of volumetric imaging.Recently,by conjugating either a movable mirror to the image plane in a remote-focusing geometry or an electrically tuneable lens(ETL)to the back focal plane,rapid axial scanning has been achieved.However,mechanical actuation of a mirror limits the axial scanning rate(usually only 10–100 Hz for piezoelectric or voice coil-based actuators),while ETLs introduce spherical and higher-order aberrations that prevent high-resolution imaging.In an effort to overcome these limitations,we introduce a novel optical design that transforms a lateral-scan motion into a spherical aberration-free axial scan that can be used for high-resolution imaging.Using a galvanometric mirror,we scan a laser beam laterally in a remote-focusing arm,which is then back-reflected from different heights of a mirror in the image space.We characterize the optical performance of this remote-focusing technique and use it to accelerate axially swept light-sheet microscopy by an order of magnitude,allowing the quantification of rapid vesicular dynamics in three dimensions.We also demonstrate resonant remote focusing at 12 kHz with a two-photon raster-scanning microscope,which allows rapid imaging of brain tissues and zebrafish cardiac dynamics with diffraction-limited resolution.Tonmoy Chakraborty Bingying Chen Stephan Daetwyler Bo-Jui Chang Oliver Vanderpoorten Etai Sapoznik Clemens F.Kaminski Tuomas P.J.Knowles Kevin M.Dean Reto Fiolka 2020Light(Science & Applications)2020,9,1:4

18River restoration challenges with a specific view on hydromorphology显示文摘1 Introduction 1.1 River ecosystem degradation Over the past century,almost throughout the whole world,streams and rivers have been heavily polluted and morphologically degraded due to industrial,household and agricultural sources,leading to significant declines in biodiversity,water quality and ultimately water supply[1-5].In the last decades,river system design has been practiced from an engineering viewpoint that focuses on water abstraction,sanitation,generation of energy,transportation and safety,rather than from a socio-ecological perspective.The technical management altered the understanding of a functioning river system itself and its social context.Jianhua LI Stephan HOERBINGER Clemens WEISSTEINER Lingmin PENG Hans Peter RAUCH 2020Frontiers of Structural and Civil Engineering2020,14,5:0
19(Not) an elementary question:How to mobilize the iron in the wall?显示文摘Photosynthesis,respiration,and countless other processes are dependent on proteins that carry iron(Fe)as an essential cofactor.When Fe was recruited for biological functions early in evolution,it was an available element.The Earth's atmosphere was reducing with oxygen limited to very low pressure.Thus,Fe was present as comparatively soluble Fe sulfides.Stephan Clemens 2021Molecular Plant2021,14,10:0
20Immunological memory: resting on two shoulders at antigen entrance sites?显示文摘Memory is a term used in two important systems:the nervous system and the immune system.Both systems need to recognize alterations and threats in an ever-changing environment.As a consequence,both systems during their evolution perfected their abilities to recall earlier challenges in mounting protective responses.This ability gives both systems the power to facilitate these protective responses if confronted with the same or similar challenges again.Clemens Wulfing Stephan Henne Jasmin Oehlmann Hauke Simon Gunther 2019Cellular & Molecular Immunology2019,16,10:0
