来自主题: _pennystock版 - 问个money flows的问题
money flow = typical price * volume
typical price for a day is the average of high, low and close
Positive money flow is the total for those days where the typical price is
higher than the previous day's typical price, and negative money flow where
below.
就出正负了。

标 题: 收了张Ticket: Parked Against Flow of Traffic
发信站: BBS 未名空间站 (Fri Apr 30 16:23:57 2010, 美东)
今天去了趟Wheaton的IRS, 结果事情没办成, 反而吃了张Ticket.
我当时停在Grandview Ave上, 是一个one-way street, meter在左边, 车就停在了
meter旁边,也就是左边.
我的理解是Parked Against Flow of Traffic是只适用于two-way的(不能停在路左侧),
因为那样说明你停的时候肯定跨中间线了, 但我在网上搜了一下没看见也适用于单行

在湾区高速上,一直follow traffic flow,后来因为GPS说接下来要keep left,于是
开到最左超车道,然后马上就被警察拦下来了。我说我一直follow traffic flow,警
察说他不能抓所有人,还说我一直在超车。在他拦下我之前,副驾一直在摄像,5分钟
的录像证明不断有车超我,而我只超了两辆大车,落后于所有小车。罚单上写speed
approx. 75+, 又注明* raced @84mph,speed limit是 65。我当时没有特别注意车速
具体是多少,75应该是有的,但有没有84我就不知道了。这种情况下应该怎么argue?
另,我刚搬到加州,还没换牌照,好像特别容易引起警察注意,前几天又被拦下说我的
牌照是卡车牌照,询问了一番。。。加州政府很缺钱吧?
再另,我想推迟trial,让警察对这件事的印象变淡再trial,这样可能要推到7月底,
那是不是应该在这之前把牌照换了?不换会不会引来新麻烦?暂时还不想换牌照、驾照
,因为我可能半年又要搬走。

Thank you very much for your great comments!
The paper is dicussing the QoS flow setup in DiffServ architecture.
They argue that the conventional DiffServ schemes assume a centralized
Bandwidth Broker (BB), which is in charge of admission control and
resource allocation, and the centralized BB could be a bottleneck
under the burst of QoS flow setup activities. So they proposed the
distributed approach, where a sink tree is constructed for each egress

我想测一个muscle/endothelial cell的体系中nitric oxide synthase的表达(只有
endothelial表达)。细胞数量很少,大约10万,所以synthase的表达估计信号也很弱
。我想测刺激
前和刺激后的synthase的表达是否有变化,我估计就算有也非常小。
这种情况下,是不是用flow会更好一点?比如如果增加只是2%,flow的结果会比较

我不是很熟western。但是我觉得western对于蛋白表达量要比较高才能看到,而且不能
定量比较(不

用western blot,测的是全部population的蛋白含量。但是如果每个细胞的蛋白含量不

sort的话,会损失很多细胞的吧。
而且我主要是觉得muscle cells会产生干扰,也许很低,也许很高;如果用flow,可以
很容易看出是否有干扰,以及干扰到什么程度。
