FAX-PC通信系统的一种实现方案

本文在介绍一般FAX-PC通信系统工作原理的基础上,提出并实现了这种通信方式的一种具体实施方案——传真通信适配器(FCA)及其支持软件。这个方案利用软硬件的紧密配合,成功地实现了G3类FAX与模拟FAX环境的PC机之间的通信。经验收使用表明,本系统性能可靠,技术先进,经济实用。     

The cellular functions of clathrin

Membranes and proteins are moved around the cell in small vesicles. A protein coat aids the budding of such vesicles from donor membranes. The major type of coat used by the cell is composed of clathrin, a three-legged protein that can form lattice-like coats on membranes destined for trafficking. In this review, I outline what we know about clathrin and discuss some recent advances in understanding the basic biology of this fascinating molecule, which include building a molecular model of a clathrin lattice and discovery of a new function for clathrin that occurs during mitosis.
