How to include PNG file in LaTeX
在LaTeX中，如果直接写:
\usepackage{graphicx}
\begin{document}
\begin{figure}
\includegraphics{test.png}
\end{figure}
\end{document}
这样就会出问题 一般是：
! LaTex Error: File ‘test.bb’ not found.
而用PdfLaTeX就没有问题 为什么呢？今天终于搞清楚了。因为png,jpg不同于eps，点阵图形里面没有包涵boundary信息，所以LaTeX没法确定边界于是就出错了。解决的方法是：
1.
\usepackage[pdftex]{graphicx}
2. 先执行一下ebb命令定好bb值
是以为记

Git的Emacs模式插件
Git是Linux内核开发同学Linus开发的一款分布式版本控制软件，详细的介绍可以看这里,这里(努力扩充中。)还有这里。Emacs天生就支持CVS和Version Control,只是缺乏一个Git后端(backend)。Git项目自己也有Emacs扩展，但是Git最重要的一个有点 方便的branch，却没有在这个很久没有新开发的git.el里面得到支持。偶然看到有一个git-emacs扩展，觉得不错，git clone了最新的1.1版本的代码，运行一下却没有git.el的菜单支持，甚不爽。于是参照了git.el里面的设置写了个菜单。和作者联系上了，准备这两天就和他的1.1版本merge。以后还准备给它加上生成patch的函数和git pull/push功能。
现预发布在这里 存成三个Emacs Lisp文件 然后byte-compile(这个随，编译以后就是运行速度快一点)然后在你的.emacs里面加上
(add-to-list ‘load-path “xxx(存放git.emacs的地址)”)
(require ‘git-emacs)
然后打开emacs M-x运行git-status就可以看到git repository里面的具体情况了
bug report, please email digitalpiglee AT gmail DOT com
附：加上Git Hosting信息:
http://github.com/tsgates/git-emacs/tree/master
已merge.

文献归纳 读书笔记 10.30
精读：
1. Kinetics of Protein Adsorption Ramsden Biopolymers on interface
2. Structural Changes in Proteins Adsorbed on Polymer Surfaces
M. E. SODERQUIST AND A. G. WALTON, Journal of Colloid and Interface Science 75 pp386
泛读：
3. A kinetic model of partially reversible protein adsorption
Paul R. Van Tassel, Pascal Viot, and Gilles Tarjus， J. Chem. Phys. 106 (2), 8， 761
All of above are talking about the mechanism of protein adsorption on solid-liquid interface. Walton demonstrate that there should be some protein conformation change when it adsorbed on the surface. The most important proof is the circular dichroism. By detecting the difference between the adsorption of alpha-helix and beta-folding, they found that the native and desorbed protein are different in conformation composition. They established a model that protein reformed itself when adsorbed on the surface, and then have different rate and somehow become irreversible adsorption process. That is also the reason for a “kink” in protein isothermal. (However, this is an old article, the data graph they used is too rough. TIRF could provide a better image, which sometimes show this “kink” while sometimes not.) They concluded that the at the latter part of the adsorption, the more important interaction is protein - protein on interface, not the protein - surface interaction.
Tassel’s paper used the idea Walton proposed. So they have the model named “partial irreversible” protein adsorption. They show the simulation result of different “surface correlation” functions. Notice that sometimes there is an “overshoot” phenomenon during the adsorption.
For us, first good news is albumin will have a 2.5mg/m2 adsorption on surface when it takes “side-on”. [2]. And albumin has a easiest tendency to have protein conformation changed, which should be considered in our case. Another thinking is if we could get the desorbed protein, we can use circular dichroism to detect if there is any conformation chance on the surface. Also, if the decrease during the adsorption observed during the protein adsorption process, maybe it’s not because of the baseline drifting. [3]
In conclusion, this process is different. Mass conservation law is only a partial thermodynamically way to describe this process. If you consider PURE kinetical way. 1) when to introduce irreversibility? 2)how to describe the reformed protein’s kinetic constant? 3)”Phase transition” on the surface?
个人感觉：美国真的很不重视理论，现在看下来，polymer brushes，还有这个adsorption kinetics都是法国人搞得有声有色。
