脑的微环路

<正>前言脑中微环路的研究,是介于还原到神经元、综合到心理与行为两个层次间的大问题。简单的定义,就是研究神经元相互之间是什么关系,几十个到几千个神经元作为整体是怎样运作的,并怎样产生高级功能的。只有理解了这个中间层次的问题,我

为什么IFPRA不成功?

非政府组织在国际社会上正起着越来越重要的作用.近几年来,在中国有许多城市获得了由国际公园与康乐协会IFPRA评选出的"国际花园城市"称号.本文从非政府组织国际公园与康乐协会IFPRA入手,解释了这个组织不够成功的原因,并提出了相应的建议.希望通过以上几点措施,IFPRA能提高影响力和知名度,真正成为一个成功的国际组织.     

Probing the Microscopic Origin of Gravity via Precision Polarization and Spin Experiments

As in other parts of physics, we advocate the interaction approach: experiments ←→ (… are influenced and their importance is determined by … and vice versa) phenomenology ←→ low-energy effective (field) theory ←→ microscopic theory to probe the microscopic origin of gravity, Using the X-g phenomenological framework, we discuss the tests of equivalence principles. The only experimentally unconstrained degree of freedom is the axion freedom. It has effects on the long-range astrophysical/cosmological propagation of electromagnetic waves and can be tested/measured using the future generation of polarization measurement of cosmic background radiation.The verification or refutal of this axionic effect will be a crucial step for constructing an effective theory and probing the microscopic origin of gravity. The interaction of spin with gravity is another important clue for probing the microscopic origin of gravity. The interplay of experiments, phenomenology and effective theory are expounded. An ideal way to reveal the microscopic origin of gravity is to measure the gyrogravitational ratio of particles, Three potential experimental methods are considered.     

Experimental Study of Effect of Medium Boundary on Light Distribution in Tissue Phantoms

An experimental method for investigating the effect of medium boundary on distributions of light in the biological tissue phantom intralipid is presented. Measurements of distributions of light in intralipid-10% suspensions at 633 nm are described, in which a narrow collimated beam is incident on the surface of the phantoms and into the different depths inside of the phantoms. The experimental results show that the effect of the boundary of the medium on the curves geometry of light distributions is trivial, but the effect on intensity of scattering light is obvious, the maximal relative change of the energy fluence reaches 53.8% and the position of the peak of the energy fluence curve has a shift of 1.1 mm in the reverse direction of incident light for the phantom with albedo a=0.998, and the effect of the boundary is decreased with the increase of the absorption coefficients of tissue phantoms. The experimental results were analysed by the diffusion theory. These studies will be helpful for further understandings of the relation between the boundary of biological tissue and the distribution of light in tissue.

基于知识管理的高校图书馆管理框架的构建

知识管理产生于企业,但不局限于企业,高校图书馆作为知识资源的管理和服务部门,应该在知识管理的推广和应用方面走在前沿,把知识创新和传播与高校图书馆的工作联系起来,以产生巨大的价值。本文从高校图书馆实施知识管理的必要性入手,构建了高校图书馆知识管理的框架。
