Hopefully it is information, not entropy, as the latter would be equivalent
to hot air, and rather useless... :-)  (Remember:  Information <> entropy!)

|
|Lavenda, B. H., "Statistical Physics", Wiley Publication, New York, 1991,
| pp. 2-11.

We don't know what's happening in a physical system when we first encounter
it.  So we make a model.  For example:  Rs is approximately equal to Rf.  But
this model doesn't work for T7 promoters, where Rs = 2 Rf, or for F incD where
Rs = 3 Rf.  So rather than getting ourselves tangles up in tautological shoe
laces, the anomalies tell us one of two things:

   1.  The idea that Rs = Rf is wrong.  If so, we can go home and work
       on something else, perhaps more useful.

   2.  The idea that Rs = Rf is right, but we didn't model the system
       correctly.  That is, we have more to learn about the system.

Either result is acceptable, though at the moment #2 has a pretty big
lead in this case.

So the "provided" means that we have to make a guess about a model
and then see how well it fits the world.

Analyst 3 has overestimated the amount of information lost when the
output is 0.  Since the input can be deduced to be one out of only
three of the four equally probable inputs, the information lost in this
case is not lb(4) but rather lb(3) = 1.58496 bits.  (Notation: ln for
natural log, lb for binary log.)  So the average information loss when
properly computed by method 3 is

	.75 * 1.58496 + .25 * 0 = 1.189 bits

in perfect harmony with analyst 1.

In general the entropy gain of a function f:A->B when A is finite is
the sum, over all a in A, of p[a]*log(q[a]/p[a]), where p[a] is the
probability of receiving an a, and q[a] is the sum, over all b in A for
which f(b)=f(a), of p[b].  The entropy gain is 0 just when no two
inputs having nonzero probability map to the same output.  Methods 1
and 3 above, when applied correctly, can be seen to be equally valid
ways of computing this gain.

Pay no attention to that middle analyst.

POSTDOCTORAL POSITION OPEN


in the "Arabidopsis Molecular Genetics" group (Group leader 
Jerome Giraudat), Institut des Sciences Vegetales (Director Adam 
Kondorosi), CNRS, Gif sur Yvette, France.

Our Institute, which is located in a multidisciplinary research 
campus of the Paris area, is composed of 5 research groups 
working on various aspects of plant molecular and cellular 
biology.

Our group is primarily studying the molecular mechanisms of 
action of the phytohormone abscisic acid: cloning and 
characterization of the abi (abscisic acid-insensitive) loci of 
Arabidopsis, and analysis of a drought adaptive response at the 
root level in Arabidopsis. In the last 6 months, we have also 
developped the characterization of Expressed Sequence Tags (EST) 
of the Arabidopsis genome: partial sequencing, and ultimately 
mapping, of cDNAs. This project is part of an ongoing integrated 
French effort which comprises of 8 different labs, and will soon 
(EEC decision pending) be part of the multinational Arabidopsis 
genome project of the EEC BIOTECH program. 

We are looking for a postdoctoral scientist which would take the 
leadership of the team working on the EST project within our 
group. Besides this responsibility, the candidate would have the 
time and the facilities to take part in one of the other ongoing 
projects, or to develop an additional project (to be discussed 
according to his personal interests), within the group.

As for the EST project, the candidate will benefit from at least 
a senior technician, one (or more) student, an automatic 
sequenator, and all necessary computer facilities.

this drug (site/mechanism of action, possible side effects, etc.)?

Especially important: the patient is diabetic.  Any possible complications?

I assume you want to measure *density* rather than volume.  How you do it
depends on what, why, and how often. 

I haven't used a real pycnometer for many years.  I have used the classical
glass bulb with capillary stopper -- my recollection is that it worked fine
but was tedious and of course required large volumes.  I also did a little
work with one of the electronic units (vibrating tube filled with liquid) 
-- I remember having problems with the calibration.  If you have many 
samples of adequate volume, this would be the easiest, but prepared to 
spend both $$ and time in calibration.  (As stated, these experiences were 
20-30 yrs ago; perhaps the electronic units are easier to use now.  
Comments from other users are welcome.)

What I currently do for checking CsCl solutions is to use a siliconized 100
microliter glass capillary pipet, weighed with and without the solution. 
I figure it's good to a fraction of a percent.  It's definitely easier than 
using a refractometer, and non-destructive.

One of the major problems in structure determination is the
determination of the structures of membrane proteins.  Success
has been achieved where the soluble portion can be cleaved off and
the structure of that portion determined.  The structures
of true membrane proteins are few and far between.  The major reason is
the difficulty in obtaining diffraction quality crystals.  Some success
has been reported with two dimensional crystals for use
in electron diffraction.

Good Luck!!
