NSA controls global Internet traffic via private fiber-optic cables
Deals brokered between federal agents and foreign corporations have allowed
the United States government to easily intercept and interpret a vast swath
of communication data sent around the world, new documents reveal.
In a National Security Agency slideshow obtained by The Washington Post and

Why do so many Chinese study physics and math relative to Americans?
The answer may be similar to why Germans, Swiss and Danes studied physics
and math, relative to Americans, prior to WWII.
That being, a long history of intellectual cultures in those other countries
and the lack of one here.
It is hard to be a cowboy and a physicist simultaneously.

你如果要和别的车比较,当然不能只看Toyota的定义,尤其是Toyota的定义和业界一般
做法不一样的时候……你如果非说RX不算多连杆,那市面上一多半的号称多连杆后悬的
车都不能算了,有意思吗?
顺道再给你讲个Toyota内部关于术语使用的事例,还是同个道理:要搞清事物本质,不
要停留在几个名词上……
事情是这样的:LFA的车架结构按惯例应该说是carbon fiber monocoque,很多车都是
类似结构,都是这么叫的,比如Aventador。但是从monocoque原本的意义上,这么用其
实不大准确,实际上LFA和市面上大多数用Aluminum spaceframe的车比较的话,结构是
类似的,只不过用碳纤组建代替了铝合金,在一个访谈里,LFA的总工本人也说,LFA绝
对不算monocoque,而是应该叫carbon fiber spaceframe。但是Lexus的官方资料里还
是按照习惯把LFA标作carbon fiber monocoque……其实这里对错无所谓,我想说的是
,你要搞清楚它的本质,叫什么反而是其次的了……

下次见OB主动提一下有家族糖尿病的事情。
我的OB是这么说的:
如果前三个月血糖控制的不好,那后面可能就更控制不住了。
一般孕妇24-28周测血糖,有家族史的会提前就开始测。我大概是20-24周因为尿
里漏糖,被抓去做糖耐,不及格被抓。
所有白的东西白米白面包就别吃了,吃全麦面包,糙米,我记得这些淀粉含量是
白米白面的70%左右,也就是说,可以多吃30%的体积。
每天早上那顿饭最重要(不是时间上的上午,是起床之后第一顿饭),如果只吃
一片面包,那比什么都不吃都要糟糕;最好吃一片面包的同时,加一个蛋,一片
肉(跑提一下,孕妇不许吃冷deli),peanut butter,这些,再喝点水,迪卡咖
啡(果汁不许喝,牛奶不许喝),这样就凑合饱了。
顺便提一下,我早餐吃一片全麦面包就还好,一片白面包,一定血糖就超标了。
不要饿到低血糖症状再吃饭,比如发抖,头晕,适度的吃零食(nuts就挺好)。
水果也不能无限制的吃,西瓜我OB不许我吃,葡萄让我一天吃7个。
适量运动,走路和游泳都是好的,餐后半小时运动对降血糖非常有效。

白米很容易便秘的。BRAT(Banana Rice Aapple source Toast)是容易便秘的食物,拉

Whole grain(这个词被商家弄得挺滥的)很多种,得学会看标签fiber含量。如oat

比一般精米面高很多。豆子、玉米、韭菜、水果(Prune, Pear, Peach,带皮的苹果(

来自主题: Immigration版 - 求评估一下O1 PP申请可行性
律师说TPC都不算,他说要session chair才可以。
另外,引用您说亮点不知道是否可以请教什么样的可以算得上亮点:
例如,有一篇review引用了我3篇文章,在文章中提到我做的东西,但不算是很详细的
评论,但好过于只有footnote。另外一篇推荐人引用我文章,他的文章基础和结果跟我
的差不多,他也在文章中提到看到有前人对这个进行过研究。这两个算是吗?
我直接列出来这个引用我三篇文章的例子吧:
One example is alkali metals, which potentially have excellent plasmonic
properties but are exceedingly difficult to handle due to their high
chemical reactivity. Moreover, application in sophisticated areas such as
superconductivity can be envisioned via including high transition
temperature met... 阅读全帖

来自主题: Immigration版 - 求教eb1a research field or General Field
小弟在研究领域具体应该是 optical fiber technology 目前所在department是
electrical and computer engineering (ECE)
照理说我的research field 最贴切的应该是 photonics and optics,optical fiber
technology; 说成是optical engineering也可以;
但是,我个人的electronics design (做电路设计,ARM,MCU,FPGA等板子,硬件编程
)也不弱,很大可能也能找到 electronics design / hardware design的工作。
现在问题来了,我的eb1a的 research field or General Field 不知该怎么报给律师?
如果写成 photonics and optics,optical fiber technology;写这个不知以后找到
electronics design的工作会不会有问题。

Keep in mind that not all sugar and fat are created equal.
There are good sugar, bad sugar, same as good fat and bad fat.
Sugar stored in fruit and vegetable are in the form of complex carbohydrate
that contain ample amounts of B
vitamins and fiber and some trace minerals. Sugar found in candy bars.etc
are simple carbohydrate.
A medium apple, for example has 80 calories, 20gm of carbs, and 0 gm of fat.
If you take a look at the chocolate nutrition label, you will see the
difference. I don't have... 阅读全帖

来自主题: Minnesota版 - chia seed有啥营养?
我查了一下,除了flax seed的好处外,独特之处有:1。亲水性,能吸附其体重十倍的
水,这样给运动员提供水
储备。2. 含fiber,外加吸水性,使碳水化合物吸收减慢,这在临床上非常受欢迎的,
称为降低了glycemic index, 预
防糖尿病,或者改善糖尿病患者的血糖控制都有良好作用。一般含fiber的食品特别是
水溶性的fiber的食品都具有
这个特性。3。因为其吸水性,增加了饱感,利于减肥。不适合你我这种需要赠肥的人
员。当然,根据我多年笑
看江湖的经验,这些特性需要临床证实,很多理论上make sense的,在实践中没有得到
证实的营养品太多了。
呵呵,所谓螺旋式上升的认识过程大概就是这样的吧。
