I want to compare two algorithms. I need the empirical data of their CPU
time. How can I do it? use special software or programming it myself using
some specific functions?

来自主题: Unix版 - how to compare date
another question:
in shell script, how to compare date? for instance, give the
"19/Mar/2002:17:14:06", ask if this time is within a specified
time slot, for example, last 50 minutes? how could you implment
it?

来自主题: Unix版 - how to compare date
you can use something like this to compare two time:
#!/bin/bash
E_NOTSAMEDAY=-197
E_PARAM_ERR=-198
if [ -z "$2" ]
then
exit $E_PARAM_ERR
fi
day1=`echo $1|cut -d: -f1`
hour1=`echo $1|cut -d: -f2`
min1=`echo $1|cut -d: -f3`
#sec1=`echo $1| cut -d: -f4`
day2=`echo $2|cut -d: -f1`
hour2=`echo $2|cut -d: -f2`
min2=`echo $2|cut -d: -f3`
#sec2=`echo $2| cut -d: -f4`
if [[ "$day1" != "$day2" ]]
then
exit $E_NOTSAMEDAY
fi
diffh=$((hour2-hour1))
diffm=$((min2-min1))

Comparing genomes to computer operating systems in terms of the topology and
evolution of their regulatory control networks
The genome has often been called the operating system (OS) for a living
organism. A computer OS is described by a regulatory control network termed
the call graph, which is analogous to the transcriptional regulatory network
in a cell. To apply our firsthand knowledge of the architecture of software
systems to understa

Hello, Friends,
When I suspect one specific mRNA is a target of one microRNA, and I didn't
get a clue from those popular web-based target prediction tools. Can I
manually compare this microRNA with the 5'UTR and 3 UTR of that mRNA for
seed matching? What software could be used for this purpose?
Thanks a lot for any pointers!

我觉得这都算一个大方向吧
comparative genomics或许是更偏evolution?但估计也是和sequence打交道吧?
你说的好发paper的,估计都是和人类疾病有关的把?
所以我觉得你的phd training的东西肯定也可以用上的,只不过evolution是冷门,更

I am sorry to tell you that there is a small hole in my proof. You have to
express the graph using the Hesse diagram, then the proof can be corrected
otherwise the "transtivity" does not hold. I check out the definition
in Math site and find it uses this definition for comparability graph:
if p<=q or q<=p, then p is connected to q. Actually, you only need one,
say, p<=q then the Hesse diagram is used:
p
|
|
q
If you don't say it clearly, then the proof may fail in this case:
p<=q

Jan. 21 (Bloomberg) -- Goldman Sachs Group Inc., facing criticism from
politicians and labor unions for near-record compensation pools, set aside $
16.2 billion to pay employees, the smallest portion of revenue since the
firm went public in 1999.
The amount, 35.8 percent of revenue, is enough to pay each of the 32,500
employees $498,246. That compares with an average pay of $316,928 a year
earlier and is down from the record $661,490 in 2007.

Can you please say more details? Do you mean I select a 5x5 window, then
calculate variance of first 3x3 pixels? then calculate all next? If that is
right, then I should get 9 variances from this 5x5 window. then average
these 9 values into one to compare?
Do you have any link for this method?
Thanks for help.
