You're blowing smoke. Qualcomm wants to sell to nice, lucrative overseas
markets like Japan and the EC. The government told them "don't do encryption
if you ever hope to export this technology". The reason that CDMA doesn't
have encryption is NOT because the G-men came a'knocking at Qualcomm's door.
It's because Qualcomm doesn't think that the US market for digital cellular
is big enough for them. This is just the International Traffic in Arms
Regulations all over again.
If you don't believe me, call Qualcomm and ASK THEM. Don't just throw
out conspicracy theories. At least, don't do it on sci.crypt--there are
whole other newsgroups devoted to this kind of uninformed claptrap.
Hah. They're not that much more expensive. Besides, if a drug dealer
can afford a Rolex and a Mercedes, he can darn well afford Cylink phones.
No, Cylink sells their phones because they're willing to make different
stuff for domestic use vs. export. Qualcomm isn't. So Cylink makes
money--that's capitalism, comrade.

That doesn't seem like a fair comparison. Infrared astronomy
didn't really get started until something like 25 yrs. ago; it
didn't explode until IRAS in 1983. Gamma-ray (and I think
X-ray) observations didn't really get started until the '70s.
I believe the same is true of ultraviolet observations in
general, and I know that extreme UV (short of 1000 Angstroms)
observations, until the EUVE (launched last year) had almost
no history except a few observations on Skylab in the '70s.
Twenty-five years ago, the vast majority of astronomers only
had access to optical or radio instruments. Now, with far more
instruments available, growth in some of these new fields has
resulted in optical work representing a smaller fraction of
total astronomical work.
fc> That would be true, if adaptive optics worked well in the visable.

Reboost may not be a problem, if they have enough fuel. If they don't do a
reboost this time, they will definitely have to do one on the next servicing
mission. But try to land a shuttle with that big huge telescope in the
back and you could have problems. The shuttle just isn't designed to land
with that much weight in the payload.
of course that is a concern too, and the loss of science during the time
that it is on the ground. plus a fear that if it comes down, some
big-wig might not allow it to go back up. but the main concern, I
believe is the danger of the landing. Just to add another bad vibe,
they also increase the risk of damaging an instrument. Finally,
this is a chance for NASA astronanuts to prove they could build and
service a space station. Hubble was designed for in flight servicing.
bringing the telescope down, to my understanding, was considered
even very recently, but all these factors contribute to the
decision to do it the way it was planned in the beginning.

2. The system implementation must make it possible to verify that the

6,349 | I've sent Gordon R. my posts on protein, vitamin C and vitamin A prior to
posting on internet as a professional courtesy. Somehow I've managed to
delete my vitamin A post from my text file. Gordon R. had promised to send
it back to me but he's pretty mad at me right now so I'll just retype it.
Since digging through all my references is very time consuming(took me all
day for that PMS post), I'm not going to cite any references(Gordon R. has
them). I'm going to include some of the material from Weinsier and
Morgan's new Nutrition textbook(which was not in my original material) to
point out that what I'm going to say has some support in the medical
community.
Diet has been know to affect the immune system of man for a very, very long
time. Protein has always had the biggest role in infection and I've
already covered the role of protein in protecting you against infection.
Now I'm going to hit what I consider to be the most important nutrient in
the U.S. as far as infection is concerned(vitamin A).
When vitamin A was originally discovered, it was commonly referred to as
the anti-infection vitamin. Many people(Linus Pauling being one) have
decided to take this title away from vitamin A and give it to vitamin C
(which I've already covered). Big mistake(in my opinion). Vitamin A is
also getting a reputation as an anti-cancer vitamin(with good reason).
The NCI currently has numerous clinical trials in progress to see if
vitamin A can not only prevent cancer but cure it as well. It's role in
both cancer and infection is almost identical(but not quite).
Vitamin A comes in two completely different forms(retinol and
beta-carotene). Retinol is the animal form and it's toxic, beta-carotene
is the plant form and it's completely nontoxic. Both retinol and beta-
carotene display good absorption in the human gut if bile is present
(60-80%). The liver stores all of your retinol and doles it out for other
tissues to use by synthesizing retinol binding protein(RBP). A normal human
adult liver should have 500,000IU to 1,000,000IU of retinol stored. We
are born with 10,000IU in our liver. U.S. autopsy has shown that about
30% of Americans die with the same(or less) amount of vitamin A as they
were born with. If you don't believe that nutritional reserves(like that
of retinol in the liver) are important, then this low vitamin A reserve is
not going to affect you. But if you believe(like I do) that the nutrient
reserves are important, then there is a problem with vitamin A in the U.S.
The U.S. RDA for vitamin A in an adult male is 1,000 RE or 5,000IU of
vitamin A. For adult feamles its 800 RE or 4,000IU of vitamin A. Diet
surveys show that most Americans are getting this amount of vitamin A
(either retinol or Beta-carotene) from their diet. But the NRC(National
Research Council) was going to release a new RDA table in 1985 that had the
RDA for both vitamin A and vitamin C raised(C to 90mg per day and A to
7,500IU per day for adult males). That report and it's recommendations was
killed. Why? Concern over the increasing supplementation was the main
reason. RDAs are set to prevent clinical disease, not to keep nutrient
reserves full. Many scientist in the U.S. feel that the time has come to
move away from the prevention of clinical pathology concept and move
towards the promotion of optimum health concept, especially since we have
some very good data now that show that nutrient reserves are extremely
important during periods of stress. The nutritonal concervatives won that
battle and a new group of scientist were collected to come out with the
1989 RDA list which lowered the RDA for several nutrients and moved the
dietary guidelines back to where they were when we first started in the
1940's(get enough to prevent clinical pathology, but not enough to fill
the reserves).
We know from autopsy that only about 10% of Americans have a liver with a
normal vitamin A reserve(500,000IU to 1,000,000IU). I preach nutrient
reserves to my students and tell them to measure them in their patients.
But for vitamin A, only a liver biopsy(or autopsy data) will tell you how
much somebody has stored. We can tell very easily if someone has
overfilled his or her liver with vitamin A by measuring the serium retinol
level(levels above 450ug/dl are highly suggestive that you have filled your
liver with vitamin A and it's time to stop taking retinol). The normal
range of serum retinol will be 20-100ug/dl. Hypervitaminosis A is
diagnosed with a serum retinol level of 2,000ug/dl or higher(Interpretation
of Diagnostic Test, Wallach, M.D., a Little Brown Series book). This level
of vitamin A in blood means that medical attention is necessary due to
vitamin A toxicity. Weinsier and Morgan take a much more conservative
approach to vitamin A toxicity than does Wallach, as you will see later in
this post. Between 450ug/dl and 2,000ug/dl you should have plenty
of warning that it's time to eliminate the retinol from your diet(headache,
redness of the skin, hair loss, joint pain).
I tell all my students that will use vitamin A in their practice that they
had better monitor the serum retinol level and stop when there are clear
signs that the liver is full. You will never really know if the patient
needs the vitamin A(because you can not measure the pool in liver) but you
will always know when it's time to stop(just like in those vitamin A for
PMS studies).
Beta-carotene can be taken to fill up your liver with retinol and you will
never have to worry about toxicity because the conversion of beta-carotene to
retinol that occurs in both your gut and your liver will slow down(stops in the
liver and slows down in the gut) when your liver is full of retinol. But
taking Beta-carotene as the source of retinol takes a very long time to
fill the liver up(I've seen estimates of 20-30 years) if you are in the 30%
that only has as much as you were born with in your liver(10,000IU). One
other problem with beta-carotene, if you have a zinc deficit, you will not
convert as much beta-carotene to retinol in the gut or the liver because the
enxzyme that does this conversion requires zinc. In addition, the release of
retinol from the liver is a zinc dependent process so a zinc deficit will
cause a vitamin A deficit even if your liver has plenty of vitamin A.
Now what does vitamin A do in cancer and infection protection? The body
uses vitamin A(retinol) for many different things. Vision(the first to be
nailed down and where you see overt clinical pathology) uses the aldehyde
(retinal) and alcohol(retinol) form of vitamin A. Reproduction uses the
retinol form and some retinal. Infection and cancer protection uses
retinoic acid. How do you convert retinol(which your white blood cells
and the mucosal cells get from blood) to retinoic acid? You use enzymes,
one of which requires vitamin C(this is why Pauling has tried to pull the
title of anti-infection vitamin away from vitamin A). Vitamin C does play
a role in infection(interferon production for example) but it's biggest role
is the conversion of retinol to retinoic acid. If you increase your intake
of vitamin C, you will increase your formation of retinoic acid. But
retinoic acid can not be converted back to retinol(as retinal can) and once
it's formed, it's used and then lost to the body. This is why the 1985 NRC
group wanted to increase both vitamin C and vitamin A RDA's.
Most people taking large amounts of vitamin C really think that they are
helping themselves. If they don't have much vitamin A in their liver and
they are not also increasing their intake of vitamin A, they actually do
themselves more harm than good.
Retinoic acid functions in white blood cells to promote antibody formation.
In the mucus membrane, it is the main factor in promoting good mucus
production and a good epithelial cell barrier to prevent infectious agents from
entering the blood system. The mucus membrane is referred to as the "first
line" defense against infection. For cancer, retinoic acid has been shown
to act as a cell brake(it counteracts the effect of cell promoters which
stimulate cells to divide). Cancer has two distinct steps, DNA alteration
and cell promotion. For cells that normally divide all the time, promoters
are not that important. But for lung and breast tissue which does not
normally divide, promoters are real important in the malignant process.
This is the major reason why the NCI has so many different clinical trials
in progress using retinol and/or beta-carotene.
Chronic infection(irritation) of the mucus membranes is a signal that
vitamin A may not be adequate. I tell my students that any patient who
walks into their office with a complaint of chronic infection has to be
worked up for vitamin A(along with the other factors that medicine already
has on it's list of causes for chronic infection). I drive this home in my
course at the Osteopathic College in Tulsa, when I teach at the allopathic
medical school in Tulsa(OU's branch campus) and when I give CME lectures.
Dark adaptation is the best clinical test for vitamin A status since night
vision is impacted when liver reverves drop to 50,000IU of retinol. The
serum level of retinol can also be used, but it does not drop until liver
reserves drop below 10,000 to 20,000IU. Asking a patient if they have
trouble seeing at night is a good initial screen(if cataracts are ruled
out). In one study done on U.S. Spanish-Americans where serum retinol levels
were measured, 25% of the sample population had a serum retinol level below
20ug/dl.
As more studies are done on serum retinol levels in population groups of
the U.S. that have had a history of high infection rates, we will probably
see a much stonger correlation between infection incidence rates and low
serum retinol levels.
What do Weinsier and Morgan have to say about vitamin A? Here are excerpts
from their book:
Vitamin A functions in vision in the forrm of retinol, it is necessay for
growth and differentation of epithelial tissue, and is required for
reproduction, embryonic development, and bone growth. Protein-calorie
malnutrition and zinc deficiency may impair the absorption, transport, and
metabolism of vitamin A. Retinaldehyde is converted to retinoic acid,
which has biological activity in growth and in cell diferentiation but not
in reproduction or vision. The most common procedure to evaluate vitamin A
status is to measure the retinol level in plasma or serum. The normal
range for vitamin A content for a child is 20 to 90ug/dl. Lower values are
indicators of deficiency or depleted body stores. Serum levels greater
than 100ug/dl are indicative of toxic levels of vitamin A. Dark adaptation
tests and electroretinogram measurements are also useful but difficult to
perform on young children. Rapidly proliferating tissues are sensitive to
vitamin A deficiency and may revert to an undifferentiated state. The
bronchorespiratory tract, skin, genitourinary system, gastrointestinal
tract and sweat glands are adversely affected. A daily intake of more than
7.5mg(about 37,000IU) of retinol is not advised and chronic use of amounts
over 20mg(100,000IU) can result in a dry and itching skin, desquamation,
erythematous dermatitis, hair loss, joint pain, chapped lips, hyperostois
(bony depositis), headaches, anorexia, edema and fatigue.
They recommend 30mg of retinol via IM injection in children for vitamin A
deficiency but do not discuss treatment for adults. Their toxic serum retinol
level is very conservative. I recommend that my students try 25,000IU in
adults that are having problems with chronic infection. They have to rule
out a zinc deficit first by getting an RBC zinc run(or if their clinical
lab can't run it, I tell them to do what Weinsier and Morgan suggest, give
them the zinc along with the vitamin A. At 25,000IU per day, toxicity
should not be a problem and you will not have to worry about pulling the
patient into the office on a regular basis to run a serum retinol.
Both Elaine and Jon found doctors who used a much higher dose of vitamin A.
Recall that the PMS papers were using 100,000IU to 200,000IU of vitamin A.
I don't suggest that my students use these high doses. If you wanted to
fill the liver up fast(as part of a clinical trial) and were monitoring the
serum retinol level, then you would be okay. But my knowledge of the
vitamin A literature suggests to me that 25,000IU for patients with a
demonstrated vitamin A deficit(dark adapatation test or serum retinol) will
provide a good and steady improvement(as long as zinc and vitamin C status
are good) without having to worry about toxicity. If they want to get more
agressive, fine if they follow my advise to check the serum retinol. But
vitamin A(retinol) should never be given in high dose to women who could
become pregnant since vitamin A shows teratogenicity towards the human
fetus. The dose needed to show this effect on the developing fetus is
18,000IU of retinol per day. Beta-carotene will never have this effect on
the human fetus.
Could just taking Beta-carotene instead of retinol supplements help? Yes
but the effect will take a long time to develop. My advise is to use
retinol to fill the liver up and then switch to beta-carotene to keep it
full. Vitamin A is probably one nutrient that is better off left to
prescription by doctors. But when we have the M.D.'s in this newsgroup
jumping all over me and other doctors that propose the use of vitamin A
supplements for treating patients with chronic sinus and GI distress, I
think that the most prudent option is to keep vitamin A in the OTC market
but require manufactors to provide package inserts to educate the general
public about the dangers of vitamin A supplementation. | 1 |

Indeed so; it's at the extreme limit of what is humanly possible. It is
possible only because Mount Everest is at a fairly low latitude: there
is a slight equatorial bulge in the atmosphere -- beyond what is induced
by the Earth's rotation -- thanks to the overall circulation pattern of
the atmosphere (air cools at poles and descends, flowing back to equator
where it is warmed and rises), and this helps just enough to make Everest-
without-oxygen feasible. Only just feasible, mind you: the guys who did

7,018 | Hello all,
There is a small problem a friend of mine is experiencing and I
would appreciate any help at all with it.
My friend has been diagnosed as having a severe case of depression requiring
antidepressants for a cure. The main problem is the side effects of these.
So far she has been prescribed Prozac, Aurorix, and tryptanol all with
different but unbearable side effects.
The Prozac gave very bad anxiety/jitters and insomina, it was impossible to
sit still for more than a minute or so.
The Aurorix whilst having a calming effect, all feelings were lost and the
body co-ordination was similar to a drunken person. Her brain was clouded
over.
The tryptanol gave tremors in the legs and panic attacks along with unco-
ordination occurred. She did not know what she was doing as her brain was
"closed down".
Has anyone had similar problems and/or have any suggestions as to the next
step?
Thankyou in advance. | 1 |

They can be detached in an emergency. But expensive hardware is not thrown
away casually (bearing in mind that nobody knew the design was defective).
If the deployment crew had found some nasty flaw -- the lid failing to open,
for example -- it would have been a bit embarrassing to have to throw the
solar arrays away to get the thing back in the payload bay. | 1 |

as one of the design alternatives which was rejected. But he's still
in there plugging. I wish him luck -- using ET's as the basis of a
Space Station has been a good idea for a long time.

Sounds pretty familiar. I posted similar cries about last September when
Caroline just entered daycare. She was two, then, and have been with
continuous colds since until last March. As spring approaches, her colds
slowed down. Meanwhile we grew more and more relaxed about her colds.
Only once did the doctor diagnosed an ear infection and only twice she
had antibiotics. (The other time was due to sinus infection, and I wished
that I did not give her that awful Septra.)
There are the 'net studies' -- that is, if you read this newsgroup often,
there will be a round of questions like this every month. There might
be formal studies like that, but bear with my not so academic experience.
Okay?
Gee, I bet 50/50 you'll hear cases in all these catagories.
I am pretty sure, an insulated child at home sicks less. But, that child
still will face the world one day.
That's what I believe and comfort myself with. Caroline will get more
and more colds for sure before she learned not to stick her hand in other
kid's mouth nor let other kids do the same. Cold virus mutate easily.
However, I hope that her immune system will be stronger to fight these
diseases, so she would be less severely affected. Everytime she has a cold,
we make sure she blow her nose frequently and give her Dorcol or Dimetapp
at night so she can have good rest (thanks to some suggestions from the net).
That's about all the care she needs from us. I try very hard to keep her
off antibiotics. Twice her ped. gave me choice to decide whether she would
have antibiotics. I waited just long enough (3-4 days) to see that she
fought the illness off. I do understand that you don't have much choice if
the child is in pain and/or high fever.
If the child doesn't rely on antibiotics to fight off the sickness everytime,
then the child should be stronger.
I'll leave this to expert.
If your child just entered daycare, I'm pretty sure the first 6 months will be
the hardest. (Then, you get more used to it. Boy, do I hate to see me typing
this sentence. I recall when I read something like this last September, I said
to myself, 'oh, sure.' But, I do get used to it, now.) However, I do hear
people say that it does get better after a year or two. I am looking forward
to a healthier next winter. As it gets warmer, I hope you do get some break
soon.
Eat well, sleep well. Try not to use antibiotics if not absolutely necessary.
Good luck.

It may be a good way to catch a cold. It's easy to pick up cold
viruses on your fingers, either from touching a contaminated surface,
or by shaking hands with someone that has a cold. Then putting your
fingers in your nose will transfer the viruses to your nose.

I'd buy that for two reasons. The tubes for TV's and radios (if you can
still find them) are usually 3x or more expensive than comparable transistors.
Also, ask any electric-guitar enthusiast which type of amp they prefer, and
they'll tell you tube-type, since tubes have lower distortion and noise
than transistors. 'Course, most of your electric guitar types just say
"Tubes sound better, dude." :-)
Also, transistors have the advantage in both waste-heat and energy-use,
mainly because of the heaters on the cathodes of the tubes.

3,483 | The clipper chip's User key is formed by:
R1 = E[D[E[N1;S1];S2];S1]
R2 = E[D[E[N2;S1];S2];S1]
R3 = E[D[E[N3;S1];S2];S1]
Why is the triple-encrytion used? Is it just to gain an effective
increase in keyspace to defeat a potential keysearch? (If so, why use
80 bit keys?) Not knowing anything about the Skipjack algorithm, it's
not really possible to guess whether this makes it harder or easier to
guess S1,S2.
Why are N1, N2, and N3 formed as they are? It would be facinating to
see the Skipjack algorithm, to look for ways of attacking it that require
three ciphertext blocks formed in that odd way.
Where do the 34-bit constant values that are concatenated with the
serial number to form N1,N2,N3 come from? Are they changed from chip to
chip, or session to session? (Even if they're published in the NY Times,
if SkipJack is resistant to known-plaintext attacks, when using triple-
encryption, then there's no break in security. But why allow that kind
of weird format? If those three 34-bit values are truly-random bits, then
maybe it's used to ensure that a known-plaintext attack on SkipJack, if
it exists, can't be easily used to derive S1 and S2 for a whole production
run of these chips....)
Does Dorothy Denning read this group? If not, is someone on the group
forwarding questions like these to her, or Martin Hellman, or anyone else
who's seen more details about the chip? | 1 |
789 | I have been looking over the postings about the Clipper Chip and noticed
an interesting omission from the discussion.
You all mention that the algorithm is classified and have expressed
concerns and ideas of how to figure out the algorithm using software.
The question that I have is why cant someone take one of these chips
and reverse engineer it? I mean, take the thing to a chip testing/
analysis facility, one with a decent electron microscope. Just pry
off the top of the chip and start scanning it with the electron
microcope and figure out the circuitry. I remembered a place that I use
to work for had one of these facilities that they used to analyze chips
that we accidently blew out while running tests. They could actually find
the area that was fried and show us where in the circuit it was.
I am sure that many companies and universities must have these facilities
and that the potential is there, especially at a university where the
security at such a facility is looser, for someone to take a clipper
apart and analyze it?
What can the government do to prevent this? Start taking away all
microchip analysis facilities and electron microscopes?? | 1 |

My apologies if this is a re-post - I submitted it on Friday, but
got a message that my post might not have gone out. Considering
the confusing spitting contest over 'rights', (there are TOO
inalienable rights damn it! The majority can be just as destructive
of liberty as a despot), I suspect that my post did not get out
of my site. (I ain't saying that dark skies are included in these
rights, although we can only preserve any rights by exercising them.)
Anyway, here are my thoughts on this:
I'd like to add that some of the "protests" do not come from a strictly
practical consideration of what pollution levels are acceptable for
research activities by professional astronomers. Some of what I
would complain about is rooted in aesthetics. Many readers may
never have known a time where the heavens were pristine - sacred -
unsullied by the actions of humans. The space between the stars
as profoundly black as an abyss can be. With full horizons and
a pure sky one could look out upon half of all creation at a time
- none of which had any connection with the petty matters of man.
Any lights were supplied solely by nature; uncorruptable by men.
Whole religions were based on mortal man somehow getting up there
and becoming immortal as the stars, whether by apotheosis or a belief
in an afterlife.
The Space Age changed all that. The effect of the first Sputniks
and Echo, etc. on this view could only happen once. To see a light
crossing the night sky and know it was put there by us puny people
is still impressive and the sense of size one gets by assimilating
the scales involved is also awesome - even if the few hundreds or
thousands of miles involved is still dwarfed by the rest of the universe.
But there is still a hunger for the pure beauty of a virgin sky.
Yes, I know aircraft are almost always in sight. I have to live
in a very populated area (6 miles from an international airport
currently) where light pollution on the ground is ghastly. The
impact of humans is so extreme here - virtually no place exists
that has not been shaped, sculpted, modified, trashed or whipped
into shape by the hands of man. In some places the only life
forms larger than bacteria are humans, cockroaches, and squirrels
(or rats). I visited some friends up in the Appalacian mountains
one weekend, "getting away from it all" (paved roads, indoor plumbing,
malls, ...) and it felt good for a while - then I quickly noticed
the hollow was directly under the main flight path into Dulles - 60-80
miles to the east. (Their 'security light' didn't help matters
much either.) But I've heard the artic wilderness gets lots of
high air traffic. So I know the skies are rarely perfect.
But there is still this desire to see a place that man hasn't
fouled in some way. (I mean they've been TRYING this forever -
like, concerning Tesla's idea to banish night, - wow!) I don't watch
commercial television, but I can imagine just how disgusting beer,
truck, or hemmorrhoid ointment advertisements would be if seen up so high.
If ya' gotta make a buck on it (displaying products in heaven), at
least consider the reactions from those for whom the sky is a last
beautiful refuge from the baseness of modern life.
To be open about this though, I have here my listing of the passage
of HST in the evening sky for this weekend - tonight Friday at
8:25 p.m. EDT it will reach an altitude of 20.1 degrees on the
local meridian from Baltimore vicinity. I'll be trying to see it
if I can - it _is_ my mealticket after all. So I suppose I could
be called an elitist for supporting this intrusion on the night sky
while complaining about billboards proposed by others. Be that
as it may, I think my point about a desire for beauty is valid,
even if it can't ever be perfectly achieved.

Something similar has happened to me - ages ago when we were working on PGP
we used to send short messages about development issues or simply to test
new features around. Now at this time PGP (and certainly the newer version)
was unknown over here. Suddenly the admin at the site I was using received
a request that I stop sending encrypted email. Now there is almost no way
that some automatic scanner could have found this, since they wouldn't have
known about PGP - they *must* have checked for unknown data types in the
message, tried to unscramble it, found they couldn't get past the PEM
armour part, and then contacted the sysadmin and asked me to stop. Luckily
the current email carriers are less picky about what goes over their
networks :-).
In case people think email scanning doesn't take place, I can assure you
that it is done regularly by many sites - usually not by government
agencies (or at least not that I know of), but by local administrators who,
for reasons of their own, have decided to monitor all communications
(I'm sure you can all think of a whole mess of reasons - stop hackers/
terrorists/child pornographers/drug dealers/evil commies/whatever). There
have been several occasions when I've got people into trouble simply by
including the traditional NSA bait in a message (I don't try it any more
now :-). A friend of mine was once picked up for mentioning the name of
the UK town of Scunthorpe (hint: look for words embedded in it). I'm sure
there are many more examples of this happening (in fact if anyone has any
examples I'd appreciate hearing from them - I could use them as
ammunition during talks on privacy issues).

My interpretation of Denning's description is that S1 and S2 are chosen
randomly by agents of the key escrow companies at the start of each 300-
chip programming session. I imagine that the chips are in a carrier which
will allow them all to be programmed fairly quickly - there would not be
a need to transfer chips one at a time into a little PLA programmer as some
people have envisioned.
My guess as to why this procedure is used is that basing the keys on the
S1 and S2 using a specified algorithm provides an (in-principle) checkable
way to verify that no back doors exist in the choice of the random numbers
used to generate the keys. Since we have to trust the escrow companies
anyway, it does not weaken the system to have the keys be generated from
random seeds entered by the escrow agents. And since the algorithm for
key-generation is public (modulo Skipjack secrecy) then in principle an
agent could challenge the procedure, ask for S1 and S2 to be exposed, and
run his own independent calculation of U1 and U2 to verify that that is
what is actually being put onto the floppies.
And yes, there are many ways in which failures to follow this scheme could
be hard to check. The laptop probably will not really be destroyed each
time. Hidden cameras in the ceiling could see the S1 and S2 entered by
the trusted escrow agents. Back doors in the chip could allow U to be
recovered. Heck, each chip could be recorded with the same U, ignoring
what was on the floppy. | 1 |

How about a mission (unmanned) to Pluto to stay in orbit and record things

Often Shuttle lifts satellites with upper stages. Yet we still consider it
payload. Ten Saturn flights over about 4 years delivered to LEO roughly the
same as 50 shuttle flights over 10 years.
They where pretty much the same in terms of cost/pound. A resurected
Saturn would cost only $2,000 per pound (if development costs are ignored)
which is five times cheaper than Shuttle.

I've got a very nice collection of historical books on medical quackery,
and on the topic of massage this is a recurring theme. Ordinary massage
is intended to make a person feel better, especially if they have muscular
or joint problems. But -- like chiropracty -- there are some practitioners
who take the technique to a far extreme, invoking what seems to me to be
quack science to justify their technique.
In the case of massage, there is a technique called "deep abdominal massage"
in which the masseur is literally attempting to massage the intestines!
The notion is that undigested food adheres to the inner surface of the
intestines and putrifies, releasing poisons which cause various disease
syndromes. By this vigorous and painful procedure, it is alleged that
these deposits can be loosened up and passed out. | 1 |

Is this "White House e-mail address" really working yet? Someone
posted such an address on CompuServe a few months ago, but apparently
the White House wasn't really set up to recive hundreds (thousands?)
of messages a day to that account and didn't want people to use it
yet. So is this MCI address something the people at the White House
actually read, or is it another Craig Shergold story? I don't know --
I'm just asking.
Unless the people at the White House print and distribute this mail
every day, you may have better luck printing out a letter (on paper,
that flat white stuff all over my desk) and Snail-Mailing it to the
White House. I imagine writing to your local representative and
senator wouldn't hurt either. Heck, why not write to Al Gore while
you're at it?

feature a new series of articles in the Morbidity and Mortality Weekly
Report on these infectious diseases (LD is one of them). We will keep you
up to date on this series.
In addition, we feature a The Wall Street Journal article on the legal issues
surrounding LD. We also look at Lyme's effects from the perspective of
urologists in an abstract entitled "Urinary Dysfunction in Lyme Disease."
Finally, Terry Morse asks an intriguing question about a tick's habitat.

III. ***** NEWS FROM THE WIRES ******
Sender: Jonathan Lord <jml4s@uva.pcmail.virginia.edu>
Subject: RESURGENCE OF INFECTIOUS DISEASE CONCERNS CDC
Date: Thursday April 15, 1993
ATLANTA (UPI) -- A resurgence of infectious diseases blamed on newly
emerging viruses and bacteria pose a major challenge for the nation's
health care system, federal health officials said Thursday.
The Centers for Disease Control and Prevention, reporting its latest
findings in an investigation of contaminated hamburger meat that
sickened hundreds in 4 states and killed at least four, said it will
put renewed emphasis on battling infectious diseases.
Part of that emphasis includes a new series titled "Emerging
Infectious Diseases" to be featured in the CDC's Morbidity & Mortality
Weekly Report, which has a wide circulation in the health community.
The issue also will top the agenda of a two-day meeting of scientific
counselors to update the CDC's draft plan for dealing with the growing
threat of infectious ailments.
"This is an issue that has been coming and we do have a responsibility
to deal with it," said Dr. Ruth Berkelman, deputy director of the CDC's
National Center for Infectious Diseases.
There were more cases of malaria in the U.S. in 1992 than in any year
since the 1960s, and Latin America is experiencing a cholera epidemic,
the first in this century, she said.
Resistance of disease-causing agents to antibiotics is also a problem.
"We are seeing much more antibiotic resistance than we have in the past"
Berkleman said. She said even common ear infections frequently seen in
children are becoming resistant to antibiotic treatment.
"Despite predictions earlier this century that infectious diseases
would soon be eliminated as a public health problem, infectious diseases
remain the major cause of death worldwide and a leading cause of illness
and death in the United States," the CDC said.
It cited the emergence since the 1970s of a "myriad" of newly
identified pathogens and syndromes, such as Escherichia coli O157:H7, a
deadly bacterial infection; the hepatitis C virus; HIV, the virus that
causes AIDS; Legionnaires disease; Lyme disease; and toxic shock syndrome.
"The incidences of many diseases widely presumed to be under control,
such as cholera, malaria and tuberculosis, have increased in many areas,"
the CDC said. It said efforts at control and prevention have been
undermined by drug resistance.

HEADLINE: Lyme-Disease Ruling Raises Liability Issues
The tick that causes Lyme disease may have found a new way to cause
damage: legal liability.
A federal judge's decision holding a property owner liable for not
doing enough to protect workers from Lyme disease is getting as much
attention as the latest medical study on the disease, a flu-like
illness that can cause severe physical and mental disabilities and in
rare instances death. The decision last week has put property owners
on notice that they may have to do more than protect themselves from
the ticks-they also may have to protect themselves from litigation if
someone becomes infected while on the property.
The decision by U.S. District Judge Robert J. Ward in New York came
after a week-long trial in a case involving four track workers for the
Long Island Railroad. Judge Ward found that the workers contracted the
disease after they were bitten by ticks while on the job. He ordered
the New York state-owned commuter line to pay the workers more than
$560,000 to compensate for pain and suffering, in addition to medical
expenses and lost wages.
Summer camps, schools, companies with facilities in rural or
semirural areas, and homeowners who rent to vacationers are among the
groups that need to be worried about this ruling, says Stephen L.
Kass, an attorney at New York law firm Berle, Kass & Case, who wrote a
legal article three years ago warning property owners of the potential
liability. Even a family that invites friends over for a backyard
barbecue might be potentially liable.
Lawsuits for insect bites, while rare, aren't unheard-of. A summer
vacationer in Southampton, N.Y., last year sued the owner of the home
she rented, claiming that a tick on the property gave her Rocky
Mountain spotted fever. In 1988, also on Long Island, a jury ordered
an outdoor restaurant to pay more than $3 million to a patron who was
stung by a bee, causing an allergic reaction and permanent
quadriplegia. The judge later threw out the award, citing no evidence
that a beehive was near the restaurant.
But lawyers say that the attention to Lyme disease throughout the
country -- it's most prevalent in New England, the Middle Atlantic
states, Wisconsin, Minnesota and the Northwest -- may make this
particular insect bite a particularly litigious one.
The illness already has proved to be a source of controversy in the
courtroom over such issues as the type of medical care insurers will
cover and medical malpractice claims against doctors for not
diagnosing the disease.
Lawyers say worker's-compensation claims related to Lyme disease
have become common in some states in recent years. Payments in
worker's-compensation cases, however, are limited to medical costs and
lost earnings.
The case before Judge Ward dealt with a potentially much more
lucrative avenue for damages, because it involved the question of
negligence. Unlike the worker's compensation process, the law governing
injuries to rail workers allows for a finding of negligence and, as a
result, for additional payments for pain and suffering. Property
owners and lawyers say that negligence claims can be made in many
other situations where people are exposed to the ticks that carry the
disease.
Ira M. Maurer, a partner at New York law firm Elkind, Flynn &
Maurer, who represented the rail workers, says the decision will help
to establish "the duty of all sorts of property owners to protect
against Lyme disease."
Lawyers caution that despite Judge Ward's decision, winning a
lawsuit for damages caused by Lyme disease may prove difficult. For
one thing, victims have to demonstrate that they have pinned down when
and where they got the tick bite. Judge Ward found that the plaintiffs
in the railroad case got Lyme disease while working on property owned
by the railroad, even though none of the men remembered being bitten.
The workers, who weren't outdoorsmen likely to be exposed elsewhere to
the insects, said they saw ticks in the high grass that surrounded
some work sites.
A spokeswoman for the railroad says that there was no proof that
the four men were bitten while on the job and that the railroad is
considering an appeal. The railroad also disputes Judge Ward's finding
that it didn't do enough to protect employees. The spokeswoman says
the railroad provides track workers with insect repellent and special
pants to protect against bug bites.
Debate in the scientific community over Lyme disease could open up
some legal defenses for property owners, such as questioning whether a
victim actually has the disease rather than some other illness.
Earlier this week, the Journal of the American Medical Association
reported that doctors overly diagnose patients as having Lyme disease.
And damages awarded to a victim also might be influenced by medical
disputes over the degree of harm that Lyme disease causes.
Because of health and safety concerns, some groups and companies
already take special measures to protect against Lyme disease. Last
year, at its headquarters in Franklin Lakes, N.J., Becton, Dickinson &
Co. began using Damminix, a pesticide made by EcoHealth Inc. of Boston
that is designed to kill ticks carrying the disease. The medical-
supply company's headquarters include a 120-acre park, and the company
was worried that employees who walk on its trails for recreation might
get infected.
Ruth Lister, a spokeswoman for the American Camping Association in
Indianapolis, says that many youth camps accredited by her
organization also have begun to check children for ticks. And Carole
Katz, a member of the board of the Fire Island Pines Property Owners
Association, says her group spends $30,000 each year to treat their
100-acre site off the coast of New York with the tick-killing
pesticide.

TITLE: Urinary dysfunction in Lyme disease.
AUTHORS: Chancellor MB; McGinnis DE; Shenot PJ; Kiilholma P; Hirsch IH,
Department of Urology, Jefferson Medical College, Thomas Jefferson
University, Philadelphia, Pennsylvania.
REFERENCE: J Urol 1993 Jan; 149 (1): 26-30
Lyme disease, which is caused by the spirochete Borrelia burgdorferi, is
associated with a variety of neurological sequelae. We describe 7 patients
with neuro-borreliosis who also had lower urinary tract dysfunction.
Urodynamic evaluation revealed detrusor hyperreflexia in 5 patients and
detrusor areflexia in 2. Detrusor external sphincter dyssynergia was not
noted on electromyography in any patient. We observed that the urinary tract
may be involved in 2 respects in the course of Lyme disease: 1) voiding
dysfunction may be part of neuro-borreliosis and 2) the spirochete may
directly invade the urinary tract. In 1 patient bladder infection by the
Lyme spirochete was documented on biopsy. Neurological and urological
symptoms in all patients were slow to resolve and convalescence was
protracted. Relapses of active Lyme disease and residual neurological
deficits were common. Urologists practicing in areas endemic for Lyme
disease need to be aware of B. burgdorferi infection in the differential
diagnosis of neurogenic bladder dysfunction. Conservative bladder
management including clean intermittent catheterization guided by urodynamic
evaluation is recommended.

Subject: Question on Lyme Vectors and Compost Piles
When I visited my sister on Long Island, NY, I was cautioned to avoid the
compost heap in her back yard, as she thinks this is where she became
infected.
A friend of mine here in Oregon who has a compost heap would like me to
back that claim up with documentation. Do lyme-carrying ticks hang out in
compost heaps?
Thank you.

These substances are normally not the secret, but how to get at them. The
method of preperation is normally patented, which means that no-one else can
make the chemical in the same way, without undergoing an agreement with
American Cyanamid. (But I guess you knew what a patent is :-) )
If you know what substance is used, you'll also know its toxicity.
The Luminol reaction has the disadvantage of not lasting as long as the
commercial version.
Remember that cyano compounds are found in nature, and not all are poisonous.

Since you asked, the above is a bit inaccurate. More accurate is that the
government says its solid, other people in the field who might be able to
find out haven't yet done their review of the chip design, and there's been
a lot of wild speculation and guesswork from those with little information
that it might be Swiss cheese.

<A circut court judge in Illinois once said "When dealing with a government

<
<(Unfortunately the comment was with regard to the banning of radar

<
<The point remains. More and more I see the government slowly washing

<
<More than the proposals themselves, I read the language of the press

<
<90%, perhaps even 95% of this country could care less about the
<clipper chip, the wiretap bill, the smart card, because they are so
<entrapped in the rhetoric of the Clinton Administration.
The problem is, the people are not having the scope, or implicataions
pointed out to them. Hell, most haven't even heard of Clipper, and
when they do, it will be in soothing language telling everyone how
nice the government is at 'letting them have' privacy.
How come the media is not telling about the provisions of the Clipper
decision? The provisions of the Crime Bill? The abuses of Civil Forfeiture?
The government uses polls to support 75 percent of the people want
gun bans, etc., yet the same pollsters have determined (according to
the media) that 30 percent of the people are unaware of what the Holocaust
is...
The people cannot be expected to give decent decisions when they are
denied the information that all these abuses and whittling away of
rights are going on quietly. When they find out (when it hits them),
it will be too late. One cannot expect each citizen to spend all their
time probing, searching, researching, etc. For example, how big a
percentage of the average population even has access to USENET? Way
less than 1 percent, I bet. How many outside of Internet/USENET
are even AWARE of what Big Brother is doing, or have been exposed to
arguments of both sides of the issue?
What the public will get is only ONE side: The Government's side.
THAT is scary.

<This saddens and frightens me.
<
<I am a conserveative believe it or not. A law and order conserveative.
<But the move to a centralized authoratarian regime really scares me,

<intelligence of the American people. Tell them it's going to keep
<them safe from drug dealers and terrorists, and they will let you

How can the bulk of the people be informed, when the media refuses to
do it?

We've been progressing towards that goal for 30 years now. We precede
any orbiting mission with flyby missions. Of course, it gets harder to
do as we work our way farther away from Earth. We're just starting to
work out to the outer planets: Galileo will orbit Jupiter, and Cassini around

6,356 | I'm a nursing student, and I would like to respond to #66966 on haldol
and the elderly.

First, I'm sorry to hear that you have had to see your grandmother go
through this. I know it has to have been tough.
There are many things that can cause long term confusion in elderly
adults. The change in environment can cause problems. Anesthetic agents
can cause confusion because the body cannot clear the medicines out of
the body as easily. In addition, medications and interactions between
medications can cause confusion.
As far as whether or not haldol can have long lasting effects even after
the drug has been discontinued, I do not know. I have not _seen_ anything
to that effect. However, I also had not been looking for that information.
I can see what I can find...
I can tell you that haldol is an antipsychotic drug, and, according to
the Nursing93 Drug handbook, it is "Especially useful for agitation
associated with senile dementia" (p. 400). It also should not be
discontinued abruptly. It did not say anything about long lasting
effects.
Because so many things can cause confusion, it is hard for me to know
what else was going on at the time; if I had more history, i might be able
to answer you better. If you want to send me e-mail with more information,
I would be happy to try to help you piece together what might have
happened. | 1 |

Why not? It hasn't been released, so there's no way for you to evaluate it
yet. After all, Apple could have been smart and had AOCE use an MD5 hash
encrypted with RSA, just like PKCS signatures. They could even be actually
PKCS compliant, for all you know; why not wait until it is released, and hard
information is available, before passing judgement on it?
AOCE's algorithm's aren't secret because Apple's being fascistic--AOCE itself
remains secret (except for Apple demos at MacWorld :)), simply because it's
not done yet.
It may be flawed, and it may not. However, you can't tell which until you
actually see it. I, at least, am quite impressed with what I have seen so
far, and have no expectation of being disappointed.

No no no no no no no.
It will go like this:
FEDS: We need the key to phone 334RE67D99.
ESCROW: You have a warrant to tap the line phone 334RE67D99 is on?
FEDS: Yes.
ESCROW: Fine, here is our key.
What happens is, Feds tap a line; find Clipper is being used; extract
serial number; get key; decipher convo. The serial number is never
registered to a specific owner, it is _sent_ as part of the
conversation. If I give you my Clipper phone, you do not need to
re-register it (mainly because it was never 'registered' to me in the
first place).
There are a lot of things that bother me about Clipper, but this is
not one of them. Let's get our facts straight and not waste effort
demolishing straw men.

Interstellar grains are not at all close to blackbodies. The "large"
grains have sizes of order 0.1 micron and absorb visible light with
fair efficiency. However, at temperatures below 100 K, 90% of the
thermal emission will be beyond 22 microns, where radiating
efficiency is poor. (A small antenna cannot easily radiate at long
wavelengths.) Thus the grains must heat up more in order to radiate
the energy they have absorbed.
Moreover, the IRAS observations had a maximum wavelength of 100
microns. Grains colder than 30 K will radiate primarily at longer
wavelengths, and IRAS would be relatively insensitive to them. In
the extreme limit, grains as cold as 5 K will be almost undetectable
by any conceivable observation.
Worse still, IRAS color temperatures are heavily contaminated by a
population of "small" grains. These grains have only perhaps 50
atoms, and when they are hit by a single photon they heat up to
temperatures of several hundred or 1000 K. Of course they cool
quickly and then stay cold for a while, but _when they are radiating_
the characteristic temperature is several hundred K. Even a small
population of these grains can dramatically raise the observed
"average" temperature.
A model for local infrared emission consistent with COBE data has
three components. These represent scattered radiation from Zodiacal
dust (color temperature 5500 K), thermal emission from Zodiacal dust
(Tc = 280 K), and thermal emission from Galactic dust (Tc=25 K). At
the ecliptic poles, the emissivities or dilution factors are
respectively 1.9E-13, 4E-8, and 2E-5. The first two are roughly
doubled in the ecliptic plane.
To find the thermal equilibrium temperature, we add up the dilution
factor times the fourth power of temperature for all components, then
take the fourth root. In the table below, starlight comes from
Allen's number that stellar emission from the whole sky is equivalent
to 460 zero mag stars with B-V color of 0.75. No doubt careful work
could do much better. (The person who suggested starlight had a
dilution factor of E-4 must have been remembering wrong. We would be
cooked if that were the case. In any event, the energy density of
starlight comes out about the same as that of the microwave
background, and I believe that to be correct.)
Dilution Temp. DT^4
Microwave background 1 2.7 53
Galactic dust 2E-5 25 8
Zodiacal dust (emission) 6E-8 280 369
Zodiacal dust (scattering) 3E-13 5500 275
Starlight 1E-13 5500 92
-----
797
The fourth root of 797 is 5.3 K. Outside the Solar system, the
result would be 3.5 K.
I find these results surprising, especially the importance of
Zodiacal dust, but I don't see any serious mistakes.

I don't think they can do that without changing the law. The chip itself
isn't classified, and reverse engineering is allowed by law (possibly)
unless prohibited by a valid contract. The algorithm may be classified,
but there are many court cases ruling that information identical to
classfied information, but obtained from unclassified sources, is freely
publishable (with the possible exception of nuclear weapon information.) | 1 |

We would like to keep it that way. Thats the point. By reacting
strongly and forcefully now, we will assure that we continue to remain
free. You cannot overreact to a threat like this. The worst that
happens if we overreact is that we waste time and effort. The worst that
happens if we underreact is tyranny. I prefer overreaction myself.
Doesn't that tell you how precious and hard to maintain freedom is?
Only through centuries of overreaction have we managed to maintain
ourselves in this state of even moderate freedom. I suggest that
overreacting now and in the future is a good thing.

Ok, so those scientists can get around the atmosphere with fancy
computer algorythims, but have you looked ad the Hubble results, the
defects of the mirror are partially correctable with software (see
those jupiter pictures for results), but is the effects are completely
reversable, why is there going to be a shuttle mission to fix it?
The way I see it (and please, astromomers give me a swift net-kick in
the butt if i'm out of the ball park), the astromers are making the
best of limited possiblities, there's only one hubble, and the shuttle
makes another in the near future a non-thought. Perhaps those self
same billboards could have small optical receptors of a limited kind
mounted on the reverse sides of the mirror's (if that is what is used)
and then the whole thing becomes a giant array telescope...

Just to set the record straight, Steve Gardner was not the author of
the bit you quoted--I was. Steve just took issue with David's
characterization of my words as "pernicious nonsense."
I won't further comment on my own views...folks either support 'em or
they don't, and the lines in question were neither central to the
points I was making in my original post nor to the important debate
here in sci.crypt and elsewhere.

5,221 | Iridology is descendant from a 19th-century theory which mapped certain
diseases to sectors of the iris of the eye. There's enough natural
variation in color that a skilled examiner can find indicators of
virtually any disease. | 1 |

Just a couple of days ago, I heard on the radio news that a Neo-Nazi
organization had set up a BBS to keep its members informed. According
to the radio man, the Nazis were using encryption to reduce their risk
if they were prosecuted. No, I do not have any more information.
Have fun.

Greg, no flame intended, but you have no discernible sense of
humor. What Bill wrote was intended to be funny. It's called a
"joke", Greg. Look into it.
Besides, Kirilian photography is actually photography of my
friend's two-year-old son Kiril. Perhaps you meant "Kirlian"?

1,486 | : Actually I am entering vet school next year, but the question is

The only suggestion i can think of off the top of my head is get a large
supply of index cards and memorize small amounts of info at a time, making
flash cards and quesitons. Everytime i get a question wrong I always
manage to get the damn thing right the next time

5,241 | I know its semantics, but the "no-op" _doesn't_ do anything. The
Command Loss Timer is simply looking for a command, any command. A
"no-op" is simply a spacecraft command that drops bits into the big
bit bucket in the sky. "No-op" also get used as timekeepers to provide
millisecond delays between command sequences (used on the thruster preps
on GRO, er, Compton) and to verify command links at the beginning of
TDRS events. All in all, a rather useful command. And, an intelligent
FDC test on Galileo (the Command Loss Timer). | 1 |

We know that sermon. It is posted roughly every month or so by different
persons, and that doesn't make it any better.
How did you get the idea that skeptics are closed-minded? Why don't you
consider the possibility that they came to their conclusions by the
proper methods? Besides, one can come to a conclusion without closing
one's mind to other possibilities.
I you don't agree with a person, please ask him why he thinks like that,
instead of insulting him. Perhaps he's right. Follow your own advice,
be open-minded.
If you don't post a bit of evidence for your claims, I'll complain that
it's always those "neither a real believer, nor a disbeliever" types who
narrow-mindedly judge others without knowing their motives.

I've seen children do this and wondered about something. If the
mucus in one's nose collects (filters) particles going into the
airway, if a child then picks and ingests this material, might
it have a vaccinatory effect, since if the body ingests airborne
diseases or other 'stuff' on the mucus, the body might generate
antibodies for this small "invasion"?
Maybe this is why some children don't get sick very often? :-)

5,063 | I am looking for statistics on the prevalence of disorders that are
treatable with Botulinum Type A. These disorders include: facial
dyskinesia, meige syndrome, hemifacial spasm, apraxia of eyelid openeing,
aberrant regeneration of the facial nerve, facial paralysis, strabismus,
spasmodic torticollis, muscle spasm, occupational dystonia (i.e. writers
cramp, etc.), spasmodic dysphonia, and temporal mandibular joint disease.
I realize many of the disorders I listed (such as "muscle spasm" !!) are
vaguely defined and may encompass a wide range of particular disorders. My
apologies; the list was provided to me as is. I have some numbers, but not
reliable.
Any ideas on sources or, even bbetter, any actual figures (with source
listed)?
Many thanks,

Hmm. This is certainly among the things I would refer to as quack
therapy and would tend to refer to any practitioner who prescribed
laetrile (whether licensed or not) as a quack. There are unethical
behaviors (such as ordering unneccessary tests to increase fees)
which I would not lable as quackish, but prescribing known ineffective
therapies seems to me to be one of the hallmarks of a quack. | 1 |
4,630 | I am currently in the throes of a hay fever attack. SO who certainly
never reads Usenet, let alone Sci.med, said quite spontaneously "
There are a lot of mushrooms and toadstools out on the lawn at the
moment. Sure that's not your problem?"
Well, who knows? Or maybe it's the sourdough bread I bake?
After reading learned, semi-learned, possibly ignorant and downright
ludicrous stuff in this thread, I am about ready to believe anything :-)
If the hayfever gets any worse, maybe I will cook those toadstools...

I'd guess this was a garbled report of the NERVA effort to develop a
solid-core fission rocket (the most mundane type of nuclear rocket).
That was the only advanced-propulsion project that was done on a large
enough scale to be likely to attract news attention. It *could* be any
number of things -- the description given is awfully vague -- but I'd
put a small bet on NERVA. | 1 |
