发帖数: 2533 | 3 Introduction:
Cells that simultaneously secrete and sense the same signaling molecule are
ubiquitous. Bacteria sense a quorum by secreting and sensing an autoinducer;
T cells induce a monoclonal
immune response by secreting and sensing a cytokine; and epithelial cells
can become cancerous through misregulated secreting and sensing of a growth
factor. Many of these cells use the same core signaling-circuit motif to
realize a diverse repertoire of biological functions. The full range of
functions ... 阅读全帖 |

牛人。
刚查了下isiknowledge，这些学校没有斯坦福牛
世界上其实只有2所牛校，专门出品牛人（但牛人不一定非从这2所出，比如藕），它们
是：哈佛大学和斯坦福大学
其他大学的所谓牛人，其实都是些混饭吃的，MIT，princeton当然不例外。
你提到的科学计算：dynamic system, bifurcation and stability analysis，
都是些没有用的东西，找不到工作的东西，有些甚至是伪科学－－wolfram的那本“a
new kind of science”就是有关的伪科学 |

发帖数: 496 | 11 If I remember this correct, bifurcated trial only applies to death penalty
cases. There should be only one trial for all other criminal actions. Does
it really split out into liability phase and penalty phase? I never read
anything like that.

发帖数: 1024 | 12 let vector v=[x(t) y(t)]', ' is transpose
A=[a b]
[c d]; assume a,b,c,d are const.
dv/dt = A *v
you can do a coordinate rotation then diagonalize matrix A.
let C be a coordinate transformation matrix
(1) dv/dt = A*C'*C*v
multiply (1) by C
(2)d(C*v) = C*A*C'*(C*v)
let vector u = C*v and matrix E = C*A*C', because E is diagonal matrix,
E11 = e1; E12=E21=0; E22 = e2;
(3) then we have,
du1/dt = e1*u1
du2/dt = e2*u2
the solution is obvious now.
bifurcation might occur. |

发帖数: 1387 | 24 现在要选课了，比较苦恼选什么课好。
上过数学系measure theory和func. analysis, 下学期准备上sde. 接着上什么？还有
什么数学基础要补充。 是不是要上些数学系的ode/pde课？ 这方面我现在就数理方法
的程度， 听他们讲什么bifurcation阿都不懂。
不过我还是很讨厌数学系的课的， 有没有什么物理课对加强quant的数学基础有帮助？
本人本科读的是物理，不过现在转系了。 |

发帖数: 22013 | 27 发现每个人说的3D都是不同的定义，
如果仅仅是纵深感的话，好像并不稀奇，有透视关系就有纵深感。
找个走廊对着尽头拍一下，想要没有纵深感都难。
另外：浅景深就是浅景深，好像也不稀奇吧。
所以我看大家讨论3d，3d的，觉得很奇怪。
FM上大多数片子我看都是普通的片子。没感觉什么特别突出的3d.
真正的3D是左右两眼分开看的那种。
仔细看了看他们的讨论
我发现我和bifurcator的感觉一样，不明白你们在说什么3d
就好像这张片子，大家都说3d，但我实在看不出什么特别的 |

leading evidence that the housing market has nowhere to go but higher.
Obviously, they will not mention the millions of houses barreling down
the foreclosure pipe -- and the approx 150k that enter the pipe every
month -- of which the vast majority will end up as inventory through
foreclosure, deeds-in-lieu or short sales.
But aside from the shadow inventory, the lack of organic inventory
