Uncovering the underlying physical mechanisms of biological systems via quantification of landscape and flux

In this review, we explore the physical mechanisms of biological processes such as protein folding and recognition,ligand binding, and systems biology, including cell cycle, stem cell, cancer, evolution, ecology, and neural networks. Our approach is based on the landscape and flux theory for nonequilibrium dynamical systems. This theory provides a unifying principle and foundation for investigating the underlying mechanisms and physical quantification of biological systems.     

基于小波变换的红外光谱分析

利用傅里叶变换红外光谱仪,借助OMNI采样器直接、快速、准确地测定了土茯苓及其三种伪品木质部的FTIR谱,采用小波变换分析法对样品进行了详细研究。结果表明：小波变换可以去除噪声和压缩变量,具有运算速度快、分析精度高以及无需去噪后处理等优点, 在红外光谱分析中具有很好的应用前景。
