Research Progress on MEF2B Gene in Human and Animals

Myocyte enhancer factor 2B （MEF2B） gene belongs to myocyte enhancer factor 2 （MEF2） gene family. They are all widely expressed in muscle and nerve tissues of human and animals. MEF2B plays an important role in the growth of muscle, development and differentiation of nerve system and liver fibrosis. This re- view mainly focused on the structural characteristics, tissue distribution, biological functions and research progress of MEF2B gene in human and animals.

派生语言值及其语义表示

本文首先引入特征值、语言值、实例值及程度分布函数待概念，然后讨论了同一实例值关于原语言值和关于其派生值的程度之间的关系，提出了程度迁移率的概念。于是我们看到，派生语言值的语义就是其原语言值语义表达式与程度迁移率的乘积。
