嗯,有几个比较喜欢的游戏。wii上面玩拳击太不过瘾了,延迟很明显。kinetic上演示
的那个格斗训练就还不错。 另外那个pose游戏也还行。那就只能先等等了

各位大佬,我们实验室发现某种激素能引起3个转录因子的相互作用 (IP and DNA
pull dwon),并协同激活基因A的表达。现在我们下一步想研究这个3个转录因子相互
结合的kinetics。这三个蛋白之中任两个的相互作用都有人研究过了。大家有什么建议
?谢谢~

标 题: 问个问题:ATRP kinetic plot 怎么作出来的?
发信站: BBS 未名空间站 (Wed Jun 15 00:26:18 2011, 美东)
就是那个图: ln [M0]/[Mt]--t 的那个图。
看到的方法有两个
1. GC
2. gravimetry
用GC的方法好理解.
但是gravimetry不知道怎么操作,有人用这个方法作过图吗?具体需要测哪些数据?
除了以上两个,还有其他方法吗?

前几天去walmart 看到 pt kinetic 特价$50 忍不住买了一个
回家上quantum 网站做点功课 发现一个有趣的问题
pt kinetic
http://www.quantumfishing.com/products/1891/Kinetic-PT.aspx
pt smoke
http://www.quantumfishing.com/products/2185/Smoke-PT.aspx
打开装配图 发现几乎完全一样
打开配件单更是大吃一惊
kinetic 售价 100 所有配件总价 235
smoke 售价 200 所有配件总价 284
更吃惊的是 smoke 的star drag 比kinetic 贵20 handle 比kinetic又贵20
去掉这俩零件 kinetic 零件总价212 smoke 零件总价 220 只差了8
请问这应该咋么理解? 纯粹是坑爹还是另有深意?
另外微粒大哥推荐过smoke 这样说来kinetic 应该也不错?
(kinetic 零件表有些零件算了两次 已经去掉)

打网球的人都知道,网球发力主要靠 kinetic chain,有的看似柔弱的人很会用
kinetic chain,球就很暴力,相反有的肌肉男不会善用这个chain,打球无力,或是有
力但出界多。另外正手反手发球的 kinetic chain 还不一样。
霏霏很会善用正手的kinetic chain,转体充分,而且姿势优雅,号称 liquid whip,
想用皮鞭抽陀螺一样。但可惜霏霏反手的kinetic chain掌握的不好。
纳豆的反手也是,chain 有点链接不好。小德就不同,链子一环扣一环,从脚到球拍,
天衣无缝。反手kinetic chain最差的是罗迪克,完全无力,但这厮发球又自创了一套
他的chain,非常有效。
总之正手反手发球三套chain都能运用自如的全才没几人。当然网球另一点是球感,就

看到拉伸瘦小腿的帖子,发现有好多对stretch & flexibility有误解,在舞言舞,说
一些dance 101的拉伸及柔软度概念
笼统地说,柔软度分三种:kinetic, passive, and active;普罗大众认为柔软度标杆
的横批竖劈其实只是passive flexibility,那kinetic和active flexibility是什么捏?
用front kick前踢打比方:
kinetic柔软度好 = 肌肉强踢得高
passive柔软度好 = 踢完了这一脚不会拉伤筋骨腿脚痛
active柔软度好 = 踢上去不借助外力保持这个pose ≈ passive + kinetic
好多人只追求passive flexibility,殊不知当三种柔软度都拥有才能算flexible,举
手投足才能干净利落,线条才会漂亮(i.e 瘦小腿)
当我们看到dancer能在空中跳跃劈叉180度,她quad需要足够强core需要足够挺竖劈可
能要拉至270度才能有这一跳
这与肌肉强弱有很大的关系,排除天生命好筋骨软的,一般柔软度好的人肌肉不会太差
,想要柔软度好自然要stretch

关于车重,IIHS有这些说明:
http://www.iihs.org/iihs/ratings/ratings-info/frontal-crash-tests
Frontal crash test results can't be used to compare vehicle performance
across weight classes. That's because the kinetic energy involved in the
moderate overlap and small overlap frontal tests depends on the speed and
weight of the test vehicle. Thus, the crash is more severe for heavier
vehicles.
Given equivalent frontal ratings, the heavier of two vehicles usually offers
better protection in real-world crashes.

(1) Why young's modulus is proportional to d2E/dr2 at r=req?
Consider a spring,
F=kx;
The potential energy E=1/2Kx^2;
K=d^2E/dx^2
(2) Why at T2, the binding potential should be like the red curve?
Generally,
Total energy = potential energy + kinetical energy
Kinetical energy = KT
T increasing results in the increase of kinetical energy and the decrease of
potential energy if total energy is conservation.

来自主题: Military版 - 学物理可以把人学疯掉!
我高中物理和大学物理都是第一,但现在发现美国的物理课本和讲义里面关于近现代物
理的错误极多,把我学得晕头转向。
比如说相速度(波长和频率的乘积)和群速度(信息或者能量传播的速度)哪一个可以
超光速的问题。我记得是相速度可以超光速,而群速度不能超光速。结果今天读到一个
网上物理讲义说在某些特殊条件下群速度可以大于相速度,所以群速度可以超光速。我
迷惑了整整半个小时才意识到这个讲义绝对是错误的。
再比如说物质波的速度与电磁波的速度比较。一个网上物理讲义说物质波的相速度可以
比电磁波的相速度高。我迷惑了整整15分钟,重新用物质波波长=h/(mv),物质波频率=
E/h,能量E=kinetic energy+rest energy,kinetic energy=1/2*mv^2,rest energy=
mc^2推公式,才意识到这个讲义绝对是错误的。
幸亏大学没有进物理系!近现代物理这么难,教授自己写课本和讲义都错误百出,那当
学生肯定要疯掉!
