DinB

The DinB gene and its protein product were first discovered in Walker's lab in 1980, long before scientists knew anything about translesion polymerases. Then graduate student Cynthia Kenyon, now a biologist at University of California, San Francisco who has done groundbreaking work on the genetic basis of aging in worms, systematically identified the genes turned on in bacteria exposed to DNA damaging agents, the so-called SOS response. Kenyon named the damaged-inducible (Din) genes in order of discovery, and DinB was the second one she found.

hyperbolic function in awk

Since:

sinh(x)=[exp(x)-exp(-x)]/2
cosh(x)=[exp(x)+exp(-x)]/2
tanh(x)=sinh(x)/cosh(x)

Therefore:

/usr/bin/awk '{print (exp($1)-exp(-$1))/2}' in.dat
/usr/bin/awk '{print (exp($1)+exp(-$1))/2}' in.dat
/usr/bin/awk '{print (exp($1)-exp(-$1))/(exp($1)+exp(-$1))}' in.dat

will give sinh, cosh, and tanh for the data inside in.dat.

An example is below, the first column is input, the rest 3 columns are output of sinh, cosh, and tanh using the above awk commands.

Multiple pages in one postscript file

The following is one postscript file with 3 pages. (I don't know why page 4 doesn't show up).
And the file doesn't always give expected result.

Looking for a research and/or service position in the field of NMR spectroscopy

I am looking for a research and/or service position in the field of NMR spectroscopy.

Generate publishable quality NMR spectrum by modifying Sparky plot ps file (3)

When postscript looks fine, open it in gimp
in the Load PostScript pop-window, Resolution 100-> 1000,
Width x10, Height x10, eg 826->8260, 1170->11700 then Ok,

It takes time to open, when finish loading, one can Crop image to get rid
of blank region, Scale image to the required size and resolution and save as tif or eps.

One can save a low resolution jpg version by modifying Scale image parameter or select a low Quality number(0-100) in the popup window after trying Save As a new.jpg
