1川滇菱形块体顺时针转动的构造学与古地磁学证据显示文摘川滇菱形块体内部受NE向丽江 -小金河断裂的切割 ,可进一步划分为川西北次级块体和滇中次级块体等南北 2个部分 ;各次级块体东边界断裂有规律地左旋滑动、西边界断裂的右旋滑动及其滑动速率值的差异 ,反映出新生代时期各次级块体作向SE的水平滑移叠加绕垂直轴顺时针转动的复合运动。其中 ,川西北次级块体SE向的水平滑移速率 5mm/a ,顺时针转动角速度 1 4°/Ma ;滇中次级块体SE向的水平滑移速率 3 5mm/a ,顺时针转动角速度约 1 5°/Ma。在滇中次级块体内部姚安、大姚、永仁、昆明北马街等地采集到约 90个古新世地层的定向样品 ,通过交变退磁和热退磁获得了它们各自的剩磁矢量 (实验磁偏角和磁倾角 ) ,由实测磁偏角与期望磁偏角相比可知川滇地区滇中次级块体中新世早期以来的顺时针转动累积量可达 30°~ 4 8°。次级块体的整体转动与块边活动断裂的左旋滑动符合左旋走滑断裂作用区块体作顺时针转动的运动学模式。徐锡伟 程国良 于贵华 宋方敏 向宏发 张兰凤 Hagai Ron 王洋龙 闻学泽 2003地震地质2003,25,1:55
2The effect of temporal variation in soil carbon inputs on interspecific plant competition显示文摘Aims Release of carbon from plant roots initiates a chain of reactions involving the soil microbial community and microbial predators,eventually leading to nutrient enrichment,a process known as the‘microbial loop’.However,root exudation has also been shown to stimulate nutrient immobilization,thereby reducing plant growth.Both mechanisms depend on carbon exudation,but generate two opposite soil nutrient dynamics.We suggest here that this difference might arise from temporal variation in soil carbon inputs.Methods We examined how continuous and pulsed carbon inputs affect the performance of wheat(Triticum aestivum),a fast-growing annual,while competing with sage(Salvia officinalis),a slow-growing perennial.We manipulated the temporal mode of soil carbon inputs under different soil organic matter(SOM)and nitrogen availabilities.Carbon treatment included the following two carbon input modes:(i)Continuous:a daily release of minute amounts of glucose,and(ii)Pulsed:once every 3 days,a short release of high amounts of glucose.The two carbon input modes differed only in the temporal dynamic of glucose,but not in total amount of glucose added.We predicted that pulsed carbon inputs should result in nutrient enrichment,creating favorable conditions for the wheat plants.Important FindingsCarbon addition caused a reduction in the sage total biomass,while increasing the total wheat biomass.In SOM-poor soil without nitrogen and in SOM-rich soil with nitrogen,wheat root allocation was higher under continuous than under pulsed carbon input.Such an allocation shift is a common response of plants to reduced nutrient availability.We thus suggest that the continuous carbon supply stimulated the proliferation of soil microorganisms,which in turn competed with the plants over available soil nutrients.The fact that bacterial abundance was at its peak under this carbon input mode support this assertion.Multivariate analyses indicated that besides the above described changes in plant biomasses and bacterial abundances,carbon supply led to an accumulation of organic matter,reduction in NO_(3)levels and increased levels of NH_(4)in the soil.The overall difference between the two carbon input modes resulted primarily from the lower total wheat biomass,and lower levels of NO_(3)and soil PH characterizing pots submitted to carbon pulses,compared to those subjected to continuous carbon supply.Carbon supply,in general,and carbon input mode,in particular,can lead to belowground chain reactions cascading up to affect plant performance.Stav Livne-Luzon Hagai Shemesh Osnat Gilor Ofer Ovadia 2016Journal of Plant Ecology2016,9,5:1

5Forward stimulated Brillouin scattering and optomechanical non-reciprocity in standard polarization maintaining fibres显示文摘Opto-mechanical interactions in guided wave media are drawing great interest in fundamental research and applications.Forward stimulated Brillouin scattering,in particular,is widely investigated in optical fibres and photonic integrated circuits.In this work,we report a comprehensive study of forward stimulated Brillouin scattering over standard,panda-type polarization maintaining fibres.We distinguish between intra-polarization scattering,in which two pump tones are co-polarized along one principal axis,and inter-polarization processes driven by orthogonally polarized pump waves.Both processes are quantified in analysis,calculations and experiment.Inter-modal scattering,in particular,introduces cross-polarization switching of probe waves that is non-reciprocal.Switching takes place in multiple wavelength windows.The results provide a first demonstration of opto-mechanical non-reciprocity of forward scatter in standard fibre.The inter-polarization process is applicable to distributed sensors of media outside the cladding and coating boundaries,where light cannot reach.The process may be scaled towards forward Brillouin lasers,optical isolators and circulators and narrowband microwave-photonic filters over longer sections of off-the-shelf polarization maintaining fibres.Gil Bashan Hilel Hagai Diamandi Yosef London Kavita Sharma Keren Shemer Elad Zehavi Avi Zadok 2021Light(Science & Applications)2021,10,7:1
