I am a math postdoc in the Simons Center for Geometry and Physics at Stony
Brook University. My research interest contains the following area: Gromov-
Witten invarants, knots invariants, and number theory. Currently, I am
working on:
1.
Matrix model, Weil-Peterson volume;
2.
Knot homology;
3.

刚发现，可能是我看的这本书上弄错了，Poincare duality只适用于closed manifold,
而那书上说是compact manifold. |

发帖数: 2385 | 11 我想系统性的重温和学习如下知识：
Differential manifolds
Tangent Space and Cotangent Space
Connections, Lie Group and Lie Algebra
Principal Fiber Bundle and related Geometry
Homotopy and homology
Gauge Theory
我以前是学数学的，希望以上的概念和知识都是从数学的角度入手：）
请版上大牛推荐一些书和Notes吧，有PDF最好啦！ |

The Riemann hypothesis is, and will hopefully remain for a long time, a
great motivation to uncover and explore new parts of the mathematical world.
After reviewing its impact on the development of algebraic geometry we
discuss three strategies, working concretely at the level of the explicit
formulas. The first strategy is "analytic" and is based on Riemannian spaces
and Selberg's work on the trace formula and its comparison with the
explicit formulas. The second... 阅读全帖 |

我给的wiki

使用化学的方法，是否化学就从属于soft matter? 当然你可以创造一个名词叫single
molecule soft matter， 那可以从属于你的soft matter但它绝对不等同于single
molecule biophy,更不等同于biophy:
比如Motor protein如何沿着actin filament行走？解旋酶如何一步一步unzip DNA? 是
否有uniform的step size? RecA/Rad51如何step by step完成homologous
recombination? DNA packaging分多少个步骤:

发帖数: 2836 | 18 what do u mean by homogeneity? If they are homologous, ur features should
pick it up
or u can say homogeneity is defined by the similarity between the feature
vectors of two languages which may or may not overlap with the ones u are
interested in.
in biology ppl build phylogenic trees,
u can do a simple hierachical clustering of the langauges using the
euclidian distanc of the feature vectors.

神经元甘氨酸受体通道的电生理研究，后来做过GABAA受体还有protocadherin蛋白的研

老年痴呆和我熟悉的GABAA受体或是protocadherin之间有关系的相关文献，有没有高人
指点一下该怎末入手设计这个面试课题啊，万分感谢。
补充一下，先前通email他们好像对我的电生理研究背景比较感兴趣，另外我熟悉的实

研究所有人做β-Site APP Cleaving Protein 1 (BACE1)和CutA Divalent Cation

现在急死了，多谢大家指点啊，要有好的idea我虽然不富， 但诚心愿意送上包子感谢

发帖数: 10103 | 23 如果不加速，那其实没啥区别，engine brake的效果会有差异。还有的区别就是AWD车
因为其AWD系
统带来的weight distribution有些不同。AWD出弯肯可以早加速，这个优势很大。
GT2不是AWD的原因很简单，因为它是要参加FIA GT2比赛的，FIA GT只不允许AWD的车。
GT2的起因是为了满足FIA的homologation要求基于911 turbo，去掉AWD系统，减重，赛道版。

发帖数: 10103 | 24 GT1应该是有homologation的规定的，停产多年的Carrera GT是不行的了。
法拉力599应该是够实力上GT1的，以前550成绩很不错的，不过跟MC12比，应该还是差
点。 |

发帖数: 19468 | 25 赛车homologation出身的超跑很多都是这样的，CLK GTR、911 GT1也都超过4米8了…… |

发帖数: 1326 | 26 看怎么用了,超跑的话,大家基本一眼能看出来是跑车。而且那些基于赛车为了符合
homologation要求的，其实和跑车的精神又不一样。我觉得跑车有一点是为了Driving
pleasure而生，赛车的话为了速度会牺牲不少易用性/舒适性，操控也会比较难驾驭，
赛车属不属于跑车其实有待商榷。
这个标准我觉得主要是为了区分那些容易和纯跑车混起来的高性能车和GT，还有国内所
谓的“轿跑车”。当然具体的车身/轴距数字上还可以调整，我就是给了个大概的数，
比如说轴距我觉得2.9米可能就太宽松了。 |

M3 GTS肯定算track car，但是track car正如你所说，可以是任何底子，和sports car
应该不是互斥的概念。这样一来，M3 GTS算不算sports car的问题还是没有解决啊…… |
