Biophysical neurons, energy, and synapse controllability: a review
Abstract: Diffusive intracellular and extracellular ions induce a gradient electromagnetic field that regulates membrane potential, and energy injection from external stimuli breaks the energy balance between the magnetic and electric fields in a cell. Indeed, any activation of biophysical function and self-adaption of biological neurons may be dependent on energy flow, and synapse connection is controlled to reach energy balance between neurons. When more neurons are clustered and gathered closely, field energy is exchanged and shape formation is induced to achieve local energy balance. As a result, the coexistence of multiple firing modes in neural activities is fostered to prevent the occurrence of bursting synchronization and seizure. In this review, a variety of biophysical neuron models are presented and explained in terms of their physical aspects, and the controllability of functional synapses, formation of heterogeneity, and defects are clarified for knowing the synchronization stability and cooperation between functional regions. These models and findings are summarized to provide new insights into nonlinear physics and computational neuroscience.

摘要:持久化内存和智能网卡等新型硬件的涌现,为文件系统架构设计带来新机遇。本文设计并实现一个基于持久化内存和智能网卡的新型文件系统NICFS。我们将NICFS分为前端与后端。在前端,数据的写入以日志结构的方式追加写到持久化内存上,从而发挥持久化内存的快速持久化优势;在后端,日志中的数据在后台被获取、处理并写入到文件中,从而充分利用智能网卡的处理能力。实验结果显示,NICFS在大粒度和小粒度的读/写性能上分别比Ext4高出约21%/10%和19%/50%。
