Yogurt contains Lactobacillus acidophilus and L. bulgaricus. L.
acidophilus is the major bacteria in the vaginal tract and is primarily
responsible for keeping the vaginal tract acidic and yeast free. Most of
the commercial yogurt sold in the U.S. has a very low L. acidophilus and L.
bulgaricus count. Neither of these bacteria are obligate anaerobes with are
much more important in dealing with the diarrhea problem. Gordon R. has told
me through e-mail that he gives his patients L. acidophilus and several
different obligate anaerobes(which set-up shop in the colon) but he hasn't
told me which ones yet. The Lactobacillus genera are mostly facultative
anaerobes and will set-up shop where they have access to oxygen if given a
chance(mouth, anus, sinus cavity and vagina). Having these good bacteria
around will greatly decrease the chance of candida blooms in the anal
region or the vagina. I have not proposed a systemic action for candida
blooms. I know that others swear that all kinds of symptoms arise from
the evil yeast blooms in the body. I'm not ready to buy that yet. I do
believe that complications at specific sites(vagina, anal and maybe lower
colon, sinus and mouth) can result from antibiotic use which removes the
competing bacteria from these sites and thus lets candida grow unchecked.
Restoring the right bacterial balance is the best way(in my opinion) to get
rid of the problem. Anti-fungals, a low carbohydrate diet and vitamin A
supplementation may all help to minimize the local irritation until the
good bacteria can take over control of the food supply again and lower the
pH to basically starve the candida out.

804 | I am quite near sighted.
I've recently received laser treatment for both eyes to seal
holes in the retinas to help prevent retinal detachment. In my
left eye a small detachment had begun already and apparently the
laser was used to "weld" this back in place as well.
My right eye seems fine. In my left eye I was seeing occasional
flashes of bright light prior to the treatment. Since the
treatment (two weeks) these flashes are now occuring more often
- several each hour.
The opthamologist explained the flashes are caused because the
vitreous body has attached to the retina and is pulling on it. He
says this is not treatable and he hopes it may go away on its own
accord - if it tugs enough I may well face retinal detachment.
I am seeking (via sci.med) additional info on retinal detachments.
The Dr. did not wish to spend much time with me in explanations
so I appreciate any further details anyone can provide. Of most
interest to me:
If my retina does detach what should be my immediate course
of action?
If conventional surgery is need to repair the detachment what is
the procedure like and what kind of vision can I expect
afterwards.
Do the symptoms (fairly frequent flashes) imply that detachment
maybe near at hand or is this not necessarily cause for alarm.
Many thanks

1,955 | OK, I heard a lot of talk about the NSA's infamous control over encryption
export through the ITAR. Here's a question. Say I develop this great new
encryption system, and I want to sell my software worldwide. The thought
police then come in and say "This algorithm is a threat to national security.
You will not be permitted to export it." At this point, what kind of trouble
could I get into if I ignored the ITAR and sold my program to international
customers anyway?
First of all, it's not the thought police, it's the export police.
If you move overseas with your great thoughts in your head, write the software there,
and then sell it, the US Thought Police probably can't do too much about it,
though you might want to check with your lawyer first.
However, if you write the program here, and sell it to furriners,
you are now an international arms dealer and can get thrown in the
clink for *many* years, especially if they decide you'd be a good example,
and Cuban Drug Dealers and Fanatic Middle Eastern Terrorists buy your stuff.
(Definitions of "public domain" are different for ITAR purposes, so if
you've got a good enough lawyer who'll do your case for free after
they've confiscated everything you own as evidence, you might win.
But nobody wants to go first, since the stakes are _quite_ high.) | 1 |
3,557 | I used to be on lopid. It did a good job of reducing cholesterol (295
down to around 214), as well as LDL and triglycerides. Then, I got
pneumonia, and for some reason, the Lopid stopped working very well;
cholesterol and triglycerides soared. The levels might have stabilized
over time, but a new doctor had me quit, wait a month, then switch
to Mevicore.
On Mevicore, my total cholesterol was down to 207, LDL was 108,
and HDL was 35; but the trig's were still
very high, around 318, and my liver tests came back slightly abnormal,
SGOT = 83 (N = 1-35), GGTP(?hard to read copy) = 42 (N = 0 - 35).
He said the liver numbers were not offbase enough to cause him
concern, and the triglycerides are not as important as the cholesterol
figures. He had me stop the Mevicore to allow the liver to heal ("Just
to be extra cautious, though I'm sure it's not a problem."),
and wants me to go back on it after that. I suggested maybe Lopid might
be the better choice, and he said that he wouldn't object if that's what
I want to do. But Lopid has one particular side effect I'm not fond of. | 1 |

2,251 | The burden of proof rests upon those who claim the existence
of this "syndrome". To date, these claims are unsubstantiated
by any available data. Hopefully, as a scientist, you would
take issue with anyone overstating their conclusions based
upon their data.
Gee, I have many interesting and enlightening anecdotes about
myself, my friends, and my family, but in the practice of
medicine I expect and demand more rigorous rationales for
basing therapy than "Aunt Susie's brother-in-law ...".
Anecdotal evidence may provide inspiration for a hypothesis,
but rarely proves anything in a positive sense. And unlike
mathematics, boolean logic rarely applies directly to medical
issues, and so evidence of 'exceptions' does not usually
disprove but rather modifies current concepts of disease.
I would characterize it not as 'abject disbelief' but rather
'scientific outrage over vastly overstated conclusions'.
I have no problem with such an approach; but this is NOT what
is happening in the 'trenches' of this diagnosis. | 1 |

I read a great book about eye dominance several years ago. So there is one
book out there..at least one :).
There were several types of eye dominance. Where a person looks in their
memory usually indicates a type of eye dominanc Another type is related to
coordination activities like hitting a ball. Another for reading.
I didn't read one that discussed prescription strength. Although people
with bad vision, near or far sighted would tend to depend on the stronger

assumed that the Command Loss Timer had that sort of function. However I
always find disturbing the oxymoron of a "NO-OP" command that does something.
If the command changes the behavior or status of the spacecraft it is not
a "NO-OP" command.
Of course this terminology comes from a Jet Propulsion Laboratory which has
nothing to do with jet propulsion.

The problem is that this will also cause "a certain amount of interference"
in *all* systems within the range of the device. A long time ago I built a
small jammer to dissuade my brother from using his radio alarm clock at
something like 4am, which had just enough range to cover my room and his.
However something powerful enough to mask all (or at least most) emissions from
your computer equipment is also going to knock out half your neighbourhoods
radio and TV reception. This isn't going to make you many friends.
Incidentally, an older-model TRS80 makes a fine wideband jammer <grin>

My opinion(for what it's worth) is that 40 x-rays is *way* too many.
Guidleines have been set on the number of dental x-rays and chest x-rays
that one should have over a given period of time because of all the
environmental factors that can cause cancer in humans, ionizing radiation
is one of the most potent(splits DNA and causes hydroxyl free radical
formation in tissue cells). Ultasound(like that used in seeing the fetus
in the uterus) has been shown to be extremely good at picking up tumors
in the prostate and gallstones in the gallbladder. But kidney tissue may
be too dense for ultrasound to work for kidney stones(any radiologists care
to comment?).
Most stones will pass(but it's a very painful process). Unlike gallstones,
I don't think that there are many drugs that can help "dissolve" the
kidney stone(which is probably calcium-oxalate). Vitamin C and magnesium
have worked in rabbits to remove calcium from calcified plaques in the
aterial wall. I have no idea if a diet change or supplementation could
speed up the process of kidney stone passage(but I'm pretty confident that
a diet change and/or supplementation can prevent a reoccurance). If surgery
is being contemplated, the stone must be in the kidney tubule. A second
opinion is a good idea because there are better(less damaging) ways to break
up the stone if it's logged within the kidney(sonic blasts). HMO's are
notorious for conservative care and long waits for expensvie treatments.

Given that certain archival methods have certain key(cleartext) in a file I
used a programatic dictionary attack. I used the DES library provided with the
system that I was using. What is to keep anyone from being lucky with a key?
My previous employment has nothing to do with my current address, other than
the fact that the fastest machine in the office was an IBM RISC System/6000
model 530, with 16 meg of memory.(not a super-computer)
I really think this more of a statement of the limitations placed on the key
by the interface(ascii char/no padding), and most programs don't bother to
clear off the archival front and backend ID's.
Yes any moderatly bright programmer with a little idle machine time, can
crack most of todays real world encryption. I sure that you or I could
select a key, and prepare the data inorder that the decryption will become a
worst case. but that is not the real world, and I'm sure that is how any
agency would start an attack on a message, as you pointed out, there are some
very good recognition algorithms availible, I'm just not familiar with them.

One possible reason is that file' is made with sassafras leaves, while root
beer was made with sassafras bark or root bark. The leaves contain either
no
or less saffrole than the bark.
There is also some sort of treatment which putatively removes saffrole from
sassafras products. I have some concentrated sassafras tea extract which
is
claimed to have the saffrole removed.
Well, the last time that I went to the store to buy sassafras bark to make
root beer, there was a sign saying that it wasn't sold for human
consumption.
Also, when I asked the person if they had wild cherry bark and wintergreen
bark,
she made a point of telling me that I couldn't buy sassafras for human
consumption.
I find the fact that some people reckless enough to step into an automobile
live

3,865 | Brad Yearwood posts a long response to the issue of registering a
phone-clipper relationship.
It doesn't wash.
Recall that law enforcement gets a court order to tap a suspect's phone
calls. They do what they do now--figure out which lines to tap. They then
record the stuff. If it's Clipper, they read the law enforcement block,
extract the serial number, and get the keys using the court order.
No new difficulties (such as using someone else's phone instrument or phone
line) are introduced that wouldn't have existed absent clipper. If the
crooks were going to use a pay phone (say), they could have done so without
clipper. If the government figures out they're so doing, they listen in, and
if it's a clipper conversation they get the serial number and then the keys.
If the crooks use an innocent person's clipper phone on the tapped line
there's no problem. The Feds don't care whose phone instrument is used, just
that the conversation is by the suspect on the tapped line. They get the
serial number, get the keys, and they are in business.
No clipper chip to person association is ever needed.

Only guessing, but from his address I'd say that Jerry, like
me, lives in Canada. Unlike me, he thinks that our friends in
the US enjoy the same freedom that we do, and he has not seen
the slow but steady erosion to the south of us.
We have the benefit of relatively slow politicians and
ineffective law enforcement. Our rednecks tend to be the
objects of derision rather than elected officials. It's
everything LE can do to keep up with the real criminals. Any
time they actually go after somebody just because they don't
like his or her attitude, it's national news (It also often
blows up in their faces: eg. the well-intentioned but flawed
Zundel case, which resulted in a scolding from the Supreme
Court, not only to LE for prosecuting the case but to
Parliament for passing the law it was prosecuted under).
Our friends south of the border don't have as easy a time of
it. Among other things they have as many LE agencies as we
have agencies, and some of them have teeth. They also have the
War on Drugs which gives law-enforcement agencies exceptional
powers to ignore individuals' rights (the DEA has more
arbitrary power than that given to Canadian agencies under the
War Measures Act). We have the RCMP and CSIS who can't stop
fighting each other long enough to do any really effective
suppression of private citizens' rights. Not only that, our
Police Commissions have teeth, as I learned when I had to fend
off a bent cop.
It may be ironic that the nation founded on Life, Liberty and
the Pursuit of Happiness is getting government-imposed order,
while the nation founded on Peace, Order and Good Government
is getting in-your-face liberty.
That's not to say our time won't come. It looks like Chretien
is going to run on a law-and-order platform. Be afraid.
Cheers,
Marc

Maybe one of you can explain this. From time to time I experience
a strange kind of feeling (I have all kinds of weird feelings) which
can be best described as the feeling of "losing gravity", like that one
experiences in a descending elevator. Needless to say, it is not
enjoyable. It sometimes comes with shortness of breath and extreme
fatigue. It lasts from a few minutes to an hour and when it lasts
that long, it makes me sweatening.
Initially I called it "palpitation (spelling?)" until I later learnt that
the terminology has been reserved for the self-awareness of heart beats.
So, is there a specific term for this feeling, or am I a stragne person?
I always believe I am unique.
Thanks. | 1 |

108 | Regarding the feasability of retrieving the HST for repair and
relaunching it:
(Caution: speculation mode engaged)
There is another consideration that hasn't been mentioned yet.
I expect that retrieving HST would involve 'damaging' it considerably in
order to return it to its cradle in the cargo bay. Most of the deployed
items (antennas and, especially, the solar arays) probably are not
retractable into their fully stowed position, even by hand. They would
have to be removed by the astronauts. (The only advantage that this
might yield is that we could put new panels on that don't 'ring' due
to thermal cycle stresses...)
I also expect that, as has been discussed, the landing loads on the
HST optics structure is a big issue (but that the reentry loads are
much less so.) Can the moveable optical components even be re-caged
(I assume that they were caged for launch)?

3,458 | I did. You're mistaken. NSA's communications intelligence mission is
strictly against foreign governments. Here's an excerpt from the enabling
charter (24 Oct 52, Truman) that should clarify this. The charter was
declassified in about Feb 1990 when an FOIA request made it public.
Interesting! Where can I get the whole thing?
NSA is not in the standard-setting business, though -- that's why this
Clipper stuff came from NIST, which I believe is tasked with coming up
with standards based on their best inputs from other government agencies,
which would include NSA.
Several of the newspaper reports have made it fairly clear that the
NSA did all the real work. You can't believe everything you read in
the papers :-), but the package of information the NIST is faxing out
has so little information beyond what's widely known that it sounds
like it's true. | 1 |
1,114 | I feel compelled to complain: the statement that recent observations
rule out merging neutron stars as sources of gamma-ray bursts is
utterly false, even though it is popular enough to make it to
BATSE press releases.
The idea behind the statement is as follows:
"if you smack two neutron
stars together, or have a neutron star be gobbled up by a black hole,
a lot of energy is released, enough for a gamma-ray burst at a
cosmological distance. But, so the reasoning continues, this energy
is released below a lot of matter, so the radiation becomes
thermalized and you expect to see roughly a blackbody spectrum.
The observed spectra are strongly non-thermal, so this model must
be wrong."
As so often, the fault lies with the imagination of the person who
was trying to prove the model wrong rather than with the model. It
may be that the initial energy release is not seen as a gamma-ray
burst, but the 'fireball' of energy and matter that is created
may spew out a relativistic flow. When this slams into the surrounding
medium, a strong flux of non-thermal gamma rays results, which may
carry off a substantial fraction of the initial total energy. All
this is not my idea: it is in a series of papers by Martin Rees,
Peter Meszaros (sorry for the missing accents:-) and co-workers.
It is certainly not a complete model, but it may well be the best one
around (summing over all proposed distance scales). An alternative
proposal for what creates the initial fireball, by the way, is the
so-called 'failed supernovae' scenario by Stan Woosley, in which
a very massive star at the end of its life collapses to a black
hole. If the stellar core was rotating, part of the infalling matter
will be temporarily halted because it is supported by centrifugal
force, and form a very dense neutron torus that accretes onto the
black hole. This beast may spew out a jet along the rotation axis,
which again constitutes relativistic flow. The rate of such
events may be much higher than that of neutron star mergers,
but the flux may be more strongly beamed, so that the net rate
of bursts observed on Earth stays the same between the two
scenarios, but the energy released per event can be a lot less
in the failed supernova scenario.
On another note: I do believe that the distance scale must
ultimately be resolved via some classical astronomical method
such as finding counterparts to the bursts at other wavelengths,
or finding a definitive signature of some known class of
objects in the distribution of positions and fluxes. Theorists
have historically not been too successfull in finding the
distance of any object by proving that there is only one
possible way in which the object can work, and therefore
it *must* be so-and-so. | 1 |
2,292 | We don't disagree on this. All I said was that a right is whatever
you or somebody acting for you can enforce. The Bill of Rights didn't
come into effect until it was ratified by the states (and indirectly,
the people); from that point it defined legal rights. "Common law"
rights are vague and situational; that's why the people insisted on a
Bill of Rights in the Constitution, spelling out exactly what they
demanded from the government. Legitimate or illegitimate, power is
power. That's why the federal government can force states to grant
their citizens rights they don't wish to: In a slugging match, the feds
win. Period.
And you're right, this doesn't belong in sci.space. I've said my
peace. No more frome me on rights (at least not here).

:a biopsy. The patient with CPH only needs to be reassured. The patient with
:CAH needs to be treated.
I just went back to the chapter in Cecil on chronic hepatitis. It seems
that indeed most cases of CPH are persistant viral hepatitis, whereas
there are a multitude of potential and probable causes for CAH (viral,
drugs, alcohol, autoimmune, etc.). Physicians seem to have a variety of
"thresholds" for electing to biopsy someone's liver. Personally, I think
that if the patient is asymptomatic, with only slight transaminitis and
normal albumin and PT, one can simply follow them closely and not add the
potential risks of a biopsy. Others may well biopsy such a patient, thus
providing these samples for study. It would be interesting to see if
anyone's done any decision analysis on this.

2,802 | Recently I've come upon a body of literature which promotes colon
cleansing as a vital aid to preventive medicine through nutrition. In
particular, Dr. Bernard Jenssen in his book "Colon Cleansing for
Health and Longevity" -- the title actually escapes me, but it is very
similar to that -- claims that regular self-administered colonics,
along with certain orally ingested "debris-loosening agents", boosts
the immune system to a significant degree.
He also plugs a unique appliance called the "Colema Board", which
facilitates the self-administration of colonics. It sells for over
$100 from a California-based company. He also plugs Vitra-Tox
products as his chemical agents of choice: these include volcanic ash,
supposedly for its electrical charge, and psyllium powder, for its
bulkiness.
If anyone knows anything about colon cleansing theory, its
particulars, or the Colema Board and related products, I'd be very
interested to hear about research and personal experience.

fasting and cleansing through a "ritual" system of purification.

I beg to differ. Chronic *active* hepatitis implies that the disease
remains active, and generally leads to liver failure. At the very
minimum, the patient has persistently elevated liver enzymes (what some
call "transaminitis"). Chronic *persistant* hepatitis simply means that
the patient has HbSag in his/her blood and can transmit the infection, but
shows no evidence of progressive disease. If I had to choose, I'd much
rather have the persistant type.

This is a whole different situation. If aliens were able to get here prior
to us being able to get there, one might conclude that they would be more advanced
and therefore "more intelegent" that we are. However if we get somewhere where there
is life, chances are we wont be able to communicate with them. So we will have
no clue as to weather they are "intelegent" or not.
That's a good point, I hadn't thought of it that way. My question however was
more along the lines of... Every year the US spends millions of tax dollars
and giving tax breaks to individuals and companies who feed the poor of foreign
countries while thousands of our own people sleep on the streets at night.
Would we give to the economicly dissadvantaged on another planet if we hadn't resolved
these issues on our own?
But... Your comment brings up another good question. Over the years we have decided
that certain cultures need improvements. The native americans is a good example. Prior
to our attempt to civilize them, the native american culture had very little crime, no
homelessnes, no poverty. Then the europeans came along and now they have those and
more. If we encounter life elsewhere, do we tell them they have to live in houses, farm
the land and go to church on sunday?

New Method For Diagnosing Alzheimer's Disease Discovered at
Huntington Medical Research Institutes: Results to Be Reported
To: National Desk, Health Writer
Contact: John Lockhart or Belinda Gerber, 310-444-7000, or
800-522-8877, for the Huntington Medical Research
Institutes.
LOS ANGELES, April 28 -- A new method for diagnosing
and measuring chemical imbalances in the brain
which lead to Alzheimer's disease and other dementias has been
discovered by researchers at the Huntington Medical Research
Institutes (HMRI) in Pasadena, Calif. Results of their research
will be reported in the May issue of the scientific journal,
Radiology.
Using an advanced form of magnetic resonance imaging (MRI)
called magnetic resonance spectroscopy (MRS), a research team led
by Brian D. Ross, M.D., D. Phil., conducted a study on 21 elderly
patients who were believed to be suffering from some form of
dementia. The exams used standard MRI equipment fitted with special
software developed at HMRI called Clinical Proton MRS. Clinical
Proton MRS is easily applied, giving doctors confirmatory diagnoses
in less than 30 minutes. An automated version of Clinical Proton
MRS called Proton Brain Examination (PROBE) reduces the examination
time yet further, providing confirmatory diagnoses in less than 10
minutes. By comparison, the current "standard of care" in testing
for Alzheimer's disease calls for lengthy memory function and
neuropsychological tests, which can be very upsetting to the
patient, are not definitive and can only be confirmed by autopsy.
In addition to Alzheimer's disease, the new Clinical Proton MRS
exam may have applications in diagnosing other dementias, including
AIDS-related dementia, Parkinson's disease and Huntington's
disease.
"We've developed a simple test which can be administered quickly
and relatively inexpensively using existing MRI equipment fitted
with either the MRS or PROBE software," said Dr. Ross, adding,
"this will help physicians to diagnose Alzheimer's earlier and
intervene with therapeutics before the progression of the disease
causes further damage to the delicate inner workings of the brain."
Dr. Ross and his HMRI team measured a family of chemicals in the
brain known as inositols, and myo-inositol (MI) acted as a marker
in the study. In comparison to healthy patients, those diagnosed
with Alzheimer's showed a 22 percent increase in MI, while their
level of another chemical called N-acetylaspartate (NAA) was
significantly lower, indicating a loss of brain-stimulating neurons
believed to be associated with the progression of the disease.
Current drug therapy for Alzheimer's disease is widely
considered to be inadequate. This is attributable, Dr. Ross
believes, to the theory that Alzheimer's is caused by an
interruption in the transmission of the chemical acetylcholine to
the nerve cells. This belief has been adhered to over the last 15
years, and consequently, most drugs to treat Alzheimer's were based
on the changing receptors for acetylcholine.
"Physicians have a real need for a test to differentiate
Alzheimer's from other dementias, to provide the patient and his or
her family with a firm diagnosis and to monitor future treatment
protocols for the treatment of this disease. For this reason, we
consider this test a major advancement in medicine," said Bruce
Miller, M.D., a noted neurologist at Harbor-UCLA, MRS researcher
and a co-author of the study.
Other members of the HMRI research team included Rex A. Moats,
Ph.D., Truda Shonk, B.S., Thomas Ernst, Ph.D., and Suzanne Woolley,
R.N. The PROBE software can be fitted on the approximately 1,200
General Electric MRI units currently in use in the United States,
and will be configured for other manufacturers' MRI units soon.

May issue, and other information, please contact John Lockhart or

Q & A on Alzheimer's Disease:
What is Alzheimer's disease and how is it caused?
Alzheimer's disease (AD) is an incurable degenerative disease of
the brain first described in 1906 by the German neuropathologist
Alois Alzheimer. As the disease progresses, it leads to loss of
memory and mental functioning, followed by changes in personality,
loss of control of bodily functions, and, eventually, death.
How many people does it affect?
Alzheimer's disease affects an estimated 4 million adults in
the United States and is the fourth leading cause of death, taking
approximately 100,000 lives each year. While Alzheimer's
debilitates its victims, it is equally devastating, both
emotionally and financially, for patients' families. AD is the
most common cause of dementia in adults. Symptoms worsen every
year, and death usually occurs within 10 years of initial onset.
What are its signs and symptoms?
Although the cause of AD is not known, two risk factors have
been identified: advanced age and genetic predisposition. The risk
of developing AD is less than one percent before the age of 50
yars old, but increases steeply in each successive decade of life
to reach 30 percent by the age of 90. In patients with familial
AD, immediate family relatives have a 50 percent chance of
developing AD. One of its first symptoms is severe "forgetfulness"
caused by short-term memory loss. Dr. Herman Weinreb of the School
of Medicine at New York University says "whether forgetfulness is
a serious symptom or not is largely a matter of degree" and
suggests the following criteria:
-- Forgetting the name of someone you see infrequently is
normal.
-- Forgetting the name of a loved one is serious.
-- Forgetting where you left your keys is normal.
-- Forgetting how to get home is serious.
Doctors suggest that people with severe symptoms should be
evaluated in order to rule out Alzheimer's disease and other forms
of dementia.

. . . David gives good explaination of the deductions from the isotropic,
'edged' distribution, to whit, they are either part of the Universe or
part of the Oort cloud.
Why couldn't they be Earth centred, with the edge occuring at the edge
of the gravisphere? I know there isn't any mechanism for them, but there
isn't a mechanism for the others either.
What on Earth is the "gravisphere"?
Anyway, before it's decay the Pioneer Venus Orbiter
had a gamma ray detector, as does Ulysses, they
detect the brightest bursts that the Earth orbit detectors
do, so the bursts are at least at Oort cloud distances.
In principle four detectors spaced out by a few AU would
see parallax if the bursts are of solar system origin.
_The_ problem with Oort cloud sources is that absolutely
no plausible mechanism has been proposed. It would have
to involve new physics as far as I can tell. Closest to
"conventional" Oort sources is a model of B-field pinching
by comets, it's got too many holes in it to count, but at
least it was a good try... | 1 |

Well, I'll avoid your question for now (got some learnin' to do) with a
promise to come back with more info when I can find it. I _do_ know that
BATSE is the primary instrument in the development of the all-sky map of
long-term sources. Given that fact, and the spacecraft attitude knowledge
of approx. 2 arcmin, we might be able to figure out how well BATSE can
determine the location (rotational) of a Gamma Ray burster from knowledge
of the all-sky map's accuracy. PR material for the other three instruments
give accuracies on the order of "fractions of a degree", if that's
any help.
Speaking of GRO, the net-world probably was happy to see that the preps
for orbit adjust appear to be going well. Our branch guy who's helping
out says that things have gone smoothly with the iso-valve preps and the
burns will take place in mid-June.
Anyway, I'm off to find out more. 'Be back when I get some info. | 1 |
5,136 | There is a description of something called a "fair crypto system" in the
May 1993 issue of BYTE, p. 134, attributed to MIT professor Silvio Micali.
The way it works is as follows:
You generate your private key S, and break it up into pieces s1, s2, s3,
s4, and s5, such that (s1 + s2 + ... + s5) mod p = S.
You give each piece s1, s2, etc. to a different escrow agency.
The agencies each compute g^sn mod p, and forward the result to the public
key telephone book keeper.
The public key telephone book keeper multiplies all the g^sn mod p, reduces
the result to mod p, and this will be the user's public key.
Now, if there were several hundered recognized escrow agencies, and the user
could give a piece of the key to each of the ones he trusted, the result would
be something of an improvement over the proposed Clipper system. | 1 |

So you have a plausible model for GRB's at astronomical distances?
I don't have any plausible models for GRBs at any distances ;-)
Recent observations have just about ruled out the merging neutron star
hypothesis, which had a lot of problems, anyhow. We have to look for
implausible models and what is fundamentally allowed independent of
models.
Hmm, the "superbowl" burst has been claimed in press releases
to cast doubt on the merging NS hypothesis, from what I've read
(and I haven't seen the papers, only the press) I'd say it is
consistent with some of the merging NS models
A paper on the possibility of GRB's in the Oort cloud just came
through the astrophysics abstract service. To get a copy of this
Here is the abstract of that paper.
...
indicator to these events all possible sources which are
isotropically distributed should remain under consideration. This is
why the Oort cloud of comets is kept on the list,
although there is no known mechanism for generating \GRBs
from cometary nuclei. Unlikely as it may seem, the possibility that \GRBs
originate in the solar cometary cloud
cannot be excluded until it is disproved.
This does not propose a _mechanism_ for GRBs in the Oort (and, no,
anti-matter annihilation does not fit the spectra at least as far
as I understand annihilation spectra...). Big difference.
That's ignoring the question of how you fit a distribution
to the Oort distribution when the Oort distribution is not well
known - in particular comet aphelia (which are not well known)
are not a good measure of the Oort cloud distribution...

Correct, we have no parallax measurements on the bursts.
Therefore, we can't tell whether they're slightly extra solar
or not!
(which means that parallax can't tell us whether or not it's real close.)

This is one of those "yes, but" things. It's true that a hydraulically
pressurized tube can be somewhat more rigid than an unpressurized tube,
but even at 2000 PSI levels a hydraulic hose will bend rather easily,
though it's straight-on compressive strength is high, and it's torsional
resistance increase is practically nil. On the other grasping member,
there's no doubt that hydraulic "leverage" exists in nature. Tree roots
are an example. Given time they can shatter concrete as osmotic pressure
increases.
Kangaroos 3-limbed? I don't think so. If you take the view that the
tail is a limb, then monkeys and kangaroos are 5-limbed. I think the
tail is a different kind of structure, grossly enlarged in the case
of the kangaroo, but primarily still an instrument of balance rather
than locomotion. I don't know much about panda "thumbs", so I'll ask
is it opposable?
Well I won't say flat out that they can't be intelligent, but I'll
bring a couple of lines of argument to bear to try to show why I
don't think it's likely. First let me say that when I say "intelligent"
I mean complex behaviors in response to novel situations on a level
with, or greater than, human tool use and tool building. IE assuming
suitable manipulators are present on the creature to allow it to alter
it's enviroment in a planned way, it will do so. That's certainly not
a universal or complete definition of intelligence, but it will suffice
for a putative technological alien.
Now no one knows exactly what makes a brain capable of thought, but
it's generally accepted that one of the criteria is a certain level
of complexity. This is generally determined by the number of neuron
cells, and their interconnections. So a creature the size of a lemur
wouldn't have enough neurons to support complex thought. This argument
is considerably less clear in the case of the dinosaur. There's room
for a large brain, though no indication that one ever developed. One
reason this may be true is neuronic speed. The electrochemical messages
that trigger neurons require time to propagate. This makes it difficult
for a highly complex central brain to coordinate the movements of very
large creatures. So there's little selection pressure for such brains.
Instead, a simpler distributed network evolves. This doesn't rule out
intelligent dinosaurs, but it points in that direction.
Then there are the thermodynamic arguments. A tiny creature like the
lemur needs to eat frequently because it's internal heat is rapidly
lost due to it's high surface to volume ratio. I contend that a creature
that must spend most of it's time and energy feeding won't have the time
to develop and exercise intelligence. That argument may be somewhat weak.
The dinosaur's problem is the reverse, it must moderate it's heat production
because it's high volume to surface ratio makes it tend to retain waste heat.
I'm assuming that a certain temperature range is optimal for chemical
reactivity reasons for productive neuron function. So creatures would
tend to need to maintain a regulated temperature in a range near that
of humans if they are carbon based. That tends to rule out cold blooded
creatures as potential homes of intelligence. Some people contend that
some of the dinosaurs may have been warm blooded. But for a creature
the size of a brontosaur, it's activity levels would have to be restrained
or it would be prone to generate an internal steam explosion from the
waste heat. Whales are similar size, but they can reject heat to the
ocean, a much more efficient sink than air. I suspect that for intelligence
to manifest itself, a certain degree of activity in interacting with the
environment is necessary. IE monkey curiousity. I doubt a large dinosaur
would be capable of that much activity.

As far as I can see if your obstetrition has an ultrasound in his rooms
and is expirienced its use and interpretation, he should be just as
capable of reading it as any radiologist. All doctors are "qualified" to
read x-rays, u/s, ct scans etc. it is just that a radiologist does nothing
else, and thus, is only better at reading them because of all this time
spent doing this (skill in reading x-rays etc. just comes from plenty of
practice). If your obstetrition reads heaps of obstetric ultrasounds he
should be able to pick up any abnormalities that can be demonstrated by
this technique.

361 | Wm Hathaway comments;
I agree that the desire for beauty is valid, but I think your desire to
impose your vision of beauty is not. You mention the age-old desire to
somehow get up there, but ignore the beauty of the actual achievment
of that vision. You mention the beauty of a very dark sky, not impeded
by the effects of humans, but ignore the beauty of the as-dark-as-can-be
sky that is only visible from space, a vision that we, or at least,
our descendents, may one day be able to see, in part, because of efforts
that others call ugly. One day, I hope, humans will be able to look out,
not upon half the heavens, with only nature-creted lights, but upon all
of the heavens, with no lights. If advertising in space can help us reach
that goal, it is no less beautiful for the way we reach it, than the
'pristine' sky of yesteryear (or yester-century), which is totally
unreachable. One of the original conceptions of beauty in wetsern
sculpture was a human form, in the effort of striving to reach a goal.
I don't think there's any reason to believe that modernity has changed that,
just because it has changed the way we strive.
BTW, there are places that people haven't fouled. Sometimes they make
it better.

4,791 | Although the $1 billion scheme is a fantasy (it's an old canard in the space
business called "trolling for billionaires"), there is a good chance that a
much smaller program ($65 million) will pass the 103rd Congress. This is the
Back to the Moon bill, put together by the people who passed the Launch
Services Purchase Act. The bill would incent private companies to develop
lunar orbiters, with vendors selected on the basis of competitive bidding.
There is an aggregate cap on the bids of $65 million.
Having a single rich individual paying billions for lunar missions is probably
worse than having the government bankroll a $65 million program, as the Delta
Clipper program has shown (DC-X was funded by SDIO at $59 million). We have a
clear chance of making a lunar mission happen in this decade - as opposed to
simply wishing for our dreams to come true. Please support the Back to the

527 | Re; Response from CoB of Boeing on SSTO ...
Boeing has been looking at several TSTO vehicles and has carried
out extensive conceptual studies of advanced launch systems for some
time. A good reference on this might be: "Comparison of Propulsion
Options for Advanced Earth-To-Orbit (ETO) Applications (IAF-92-
0639)." by V.A. Weldon and L.E. Fink from Boeing. The paper
describes a propane-fueled TSTO launch system claimed to achieve
aircraft-like operational efficiencies without the problems
associated with liquid hydrogen fuel. Basically, it's a high-speed
airplane launching a Hermes-type spaceplane
The design (the concept is also called "Beta") as laid out in the
paper can launch at least 10,000 pounds into polar orbit, or 20,000
pounds to space station orbit including a crew of eight persons and
life support. System design reliability is .9995.
Beta is a 360-foot-long first stage powered by two large ramjets
and 12 high- speed civil transport (HSCT) turbofans. A 108-foot-
long reusable orbiter is trapeze-mounted in the belly of the first-
stage aircraft, which also could accommodate a longer and heavy
payload on an expendable second stage.
To launch the orbital vehicle, the first stage takes off like a
normal HSCT and accelerates to Mach 3. At that point the turbofans,
modified to burn catalyzed JP-7, would shut off and the ramjets,
would take over. At Mach 5.5 the orbiter or the ELV would swing
out, ignite and proceed to orbit. Both vehicles would land like
aircraft at the conclusion of their respective missions.
Estimated total weight of the combined configuration at takeoff
is about 1.5 M lbs, roughly equivalanet to a fully loaded An-225.
The orbiter stages weighs about 400,Klbs including 335 Klbs
of LOX and subcooled propane to power two 250 Klbs vacuum thrust
rocket engines. Propellants would be stored at 91 degrees Kelvin,
with the propane in a spherical tank mounted forward of the 15-by-
25-foot cargo bay and the two-seat orbiter crew station. LOX would
be stored aft. Weldon and Fink claim the key to this design's
success is the structurally efficient airframe and the compact
tankage allowed by the high-density supercooled hydrocarbon fuel.
The paper compares TSTO design to SSTO design. They conclude
while a SSTO has a slightly lower recurring cost, a TSTO is easier,
cheaper, and less risky to develop, simpler to build, has greater
safety and mission versatility and doesn't carry the hard-to-handle
and bulky hydrogen fuel. The conlcude "In conjunction with its major
use of airplane type engines and fuel, as well as its inherent self-
ferry capability, it is probably the system most likely to provide
as close to airline-like operations as possible with a practical
configuration, until a single stage airbreather/rocket concept can
be shown to be operationally viable."
Weldon and others at Boeing have been working on TSTO designs for
some time. I expect this, or a similar concept (perhaps the HTHL
SSTO they proposed for the SDIO SSTO first phase) is being re-
examined as a basis for a bid on the first phase of SpaceLifter.
Does it threaten DC-???. Possibly -- There is a set of on-going
studies trying straighten out the government's future space
transportation strategy. MDC and Boeing (as well as other firms)
are providing data to a joint study team back in DC. There are
various factions and options vying for attention -- including
shuttle upgrades, shuttle replacement (what was called the "4-2-3"
architecture), SpaceLifter, ELV upgrades, and various advanced
vehicles (ALES, Beta, DC-??, NASP, FSTS, SSTOs of several types,
etc.) NASA/DOD/DOT are trying to put together a coherent strategy
for future US gov't space transportation systems, and trying to
juggle near-term launch needs (like for DoD and NASA) against
medium-term needs (including commercial considerations), and against
the investment and risk of going to "leap frog" new technologies
like SDIO/SSTO and NASP and Beta.
It's a heck of a problem. The worst part of the problem isn't
that there aren't promising ideas and concepts -- there are dozens
of them -- but how they balance cost and risk versus real needs in
the near term. They should have a draft report in mid-June, with a
final report coming by the end of the fiscal year.

6,350 | It is interesting to note in the past few days' correspondance that some
believe that poor old New Mexico is not capable of hosting a commercial
space launch business. For many reasons, it can, and we here on the front
lines see no reason why it should not. The 'spaceport political publicity'
referred to the other day had its intended effect - the state of New Mexico
did establish the start of the necessary government infrastructure to back a
commercial space port. The commanding general at WSMR is in full support of
dual-use for the facilities. The WSMR location also has some strategic
advantages in the form of necessary infrastructure and controlled air space
to support the project. Just because the folks involved have not done the
traditional aerospace-equivalent of vapor-ware by inviting folks out to kick
non-existent tires but have been merely doing their job to prepare for
launch, don't think that nothing has happened. From my interactions with
the MACDAC folks, I get the impression that they want to set a firm,
believable launch date based on vehicle readiness and not just some fiction
to plug a space on a calendar. I believe that all will happen this summer
and don't worry, the locals here are planning to let everyone know when it
does occur.

I don't think there is a general distinction. Rather, there are
two classes of chronic hepatitis: chronic active hepatitis and chronic
persistent hepatitis. I can't think of any other disease where the
term persistent is used with or in preference to chronic.
Much as these two terms "chronic active" and "chronic persistent"
sound fuzzy, the actual distinction between the two conditions
is often fairly fuzzy as well. | 1 |

Do not presume to tell me what I have and have not read. The system may
not rely upon registering people as owning particular phone units, but
it is necessary to know which phone units are likely to be used for some
suspected criminal communication before you can obtain their unit keys
from escrow. This necessity raises the stakes in favor of a criminal's
coercing or colluding use of some other person's Clipper phone.
I will restate my assumptions more explicitly and amplify my argument.
The original title perhaps should have been "Distinction between legal
and illegal cipher systems considered harmful", but "Clipper considered
harmful" is not inaccurate, and is more eye-catching in the current context.
Assumptions:
1. Clipper is made available.
2. Laws are passed to make use of cipher systems other than Clipper illegal
(either on radio systems, or on any common carrier system). These laws
also include enforcement authority to listen across the relevant radio
spectrum (or other medium), characterize signals, validate Clipper
wrappers, detect probable use of non-Clipper ciphers, and make such
detection a cause for further action.
3. For escrowed keys to be useful, some specific Clipper chip must be
associated with a suspected criminal. This means that at a minimum
some association between the common carrier's unique phone ID (ESN) and
the Clipper chip serial number N will be stored in a government database.
An observed pairing of N and ESN other than the one recorded raises a
red flag.
4. To reduce ordinary fraud, the cellphone system which offers Clipper
will also be constructed with an ESN mechanism much more tamper-proof
and much less spoofable than today's cellphones.
5. Criminals want inscrutable communications. Some criminals are not
entirely stupid or ignorant, and will figure out both that Clipper
cellphones offer excellent security in normal circumstances, and that
they offer no security against law enforcement once a (presumably
legitimate) wiretap order exists. They will also figure out that the
wiretap order must necessarily be against a specific cellphone, because
each one has a unique unit key.
6. Criminals do not want to call attention to themselves. Because they
are not stupid or ignorant (or because they read netnews), and because
they know that their open use of a non-Clipper cipher is likely to be
detected, they will generally avoid using non-Clipper ciphers directly
on some monitorable/tappable channel. They know that do so would raise
a red flag, putting a given cellphone (if not a given person) under
immediate suspicion.
7. It is impractical to reverse engineer Skipjack, discover family key F,
and construct a functional clone of a Clipper chip.
By #2, #3, #4, and #7 it will be very difficult to spoof a given Clipper
phone without immediate detection. Because it is difficult to obscure one's
association to a specific phone by reprogramming or changing chips
around, the criminal will be motivated to find an intact phone which is
associated with someone else.
A non-stupid criminal will conclude that they can have Clipper-secure
communications, at least for some limited time T, if they buy, beg, borrow,
or steal use of someone's phone in a way that prevents that person from
reporting compromise of the phone for at least time T. The encrypted
communications might have been recorded, and thus be retrievable later,
but the criminal can delay, and quite likely evade, discovery by destroying
or abandoning the phone before T elapses.
It would be unusual for an innocent person to volunteer use of their Clipper
phone to someone else. The honest subscriber doesn't want to pay someone
else's bill, and he doesn't want to fall under suspicion.
This leaves two sources of Clipper phones for criminal use: coercion
and collusion.
Coercion first. Theft bears a relatively low risk, but also sometimes
a low time until detection (a few minutes if a phone is stolen from
a car parked in front of a store, a couple of weeks if a phone is stolen
from someone who is away on vacation). Criminal commerce is likely to
arise in stolen Clipper phones, with phones coming from risk-inured poor
criminals, and cash coming from risk-averse wealthy criminals. Someone
who is extraordinarily motivated to gain a day or two of undetected
communication (like a terrorist) could kill a person or hold them hostage.
The limited time (before detection) that a coerced phone is useful means
that continuing criminal enterprises require a continuing supply of
freshly coerced phones.
There would also be created a collusive commerce between relatively
wealthy criminals, and ignorant or don't-care patsies who need money,
and who will submit to being paid in return for subscribing to Clipper
phone service for someone else's use.
Criminals will learn that it is more to their advantage to coerce use of a
Clipper cellphone than it is to apply a non-Clipper cipher to a normal
cellphone. They will call much less attention to themselves (or at least to
their stolen phone) this way. The fact of a phone's use being coerced must
first be reported before it can be identified as an interesting phone, and
have its keys obtained from escrow.
Clipper also allows an extraordinary opportunity for the criminal to
conceal use of super-encryption. An automated full-system surveillance
mechanism (quite feasible across radio bandwidth) which knows family key F,
can validate Clipper wrappers and N:ESN associations, but it cannot reveal
in realtime the use of super-encryption, unless it knows all unit keys,
which we are being assured are only to be made available in two separate
pieces, upon specific wiretap-like order.
Whereas a criminal's use of any cipher within a normally cleartext medium
would stand out, a criminal's use of a non-Clipper cipher within a Clipper
medium would be very difficult to detect, even ex post facto in bulk
recordings, as long as the association between criminal and specific Clipper
chip is fractured.
If you make use of this other cipher illegal per se, then you can charge
the criminal with this (if you can identify the true criminal - he'll be
using someone else's phone), but you'll have no evidence to help you against
whatever traditional crime he might have been planning. You will not even be
able to detect that unusual (encrypted) communications are occurring until you
identify specific phones and obtain their keys from escrow.
The gangster and terrorist are thus arguably more, not less, secure than
they were before Clipper came along.
I therefore consider Clipper harmful because:
1. It does not provide absolute privacy to the honest public against
aggressive or dishonest government.
2. If other ciphers are proscribed, it engenders new types of direct
criminal threat to the honest public.
3. It provides an extraordinarily effective mechanism for criminals to
hide their use of some other cipher, making it more difficult than
ever even to gain notice that unusual communications are occurring
and that plans for some criminal act might be in progress.
4. If other ciphers are proscribed, lazy investigators and prosecutors
are more likely to pursue the easily quantifiable cipher-use crime
than they are the traditional and directly harmful crimes which key
escrow is claimed to help against.
5. If other ciphers are proscribed, the stage is set for witch hunting
of "illegal" cipher use. Because any computer can be used as a cipher
machine... | 1 |

3,340 | I don't wish to rehash the PGP patent issue at all, but I do feel
that some potential misconceptions in interpretting intellectual property
laws need to be raised.
You are correct that executing PGP would be a violation (unless the patent
were declared invalid by the courts), but... there is a question as
to when, how, or if distributing PGP would be a violation. If the person
or company distributing PGP receives money for doing so, then it is
clearly a sale (for example, if it were on Compuserve, they charge you
for access so they would be selling PGP). When there is no charge for
PGP things get less clear, but there would still be a reasonable view
that it is inducing an infringement.
This is a common misconception. The patent laws do not mention any valid
purpose for infringing a patent. Although it is clear that in order to
create a new invention either based on a prior patent or to avoid infringing
a prior patent, one must perform research on an existing patent. To
just say that you infringed a patent (assume we're not talking the RSA
patent) only for research purposes (wink wink, nudge nudge) and then never
develop any related invention (ie. only use it), would be a clear
infringement.

One very interesting thing I notice about this is that the only use of
the chip key is to encode the session key for the law enforcement field.
It is not used at all by the encryption algorithm.
It seems like it would be possible to create a device that would be
otherwise compatible, but would send out a bogus law enforcement field.
This might render the device unusable with "normal" devices if there's
some sort of validation involving the law enforcement field, but it
could certainly be used with other such modified devices.
Of course, this is irrelevant if the NSA has a backdoor in the
algorithm, but it does make it possible to defeat the key escrow system.

6,381 | A student told me today that she has been diagnosed with kidney stones, a
cyst on one kidney, and a kidney infection. She was upset because her
condition had been misdiagnosed since last fall, and she has been ill all
this time. During her most recent doctor's appointment at her parents'
HMO clinic, she said that about FORTY! x-rays were made of her kidney.
When she asked why so many x-rays were being made, she was told by a
technician that they need to see the area from different views, but she
says that about five x-rays were made from EACH angle. She couldn't help
feeling that something must be wrong with the procedure or something. She
is a pre-med student and feels she could have understood what was
happening if someone would have explained. When nobody would, she got
worried.
Also, she is told that thre are 300! surgery patients ahead of her
and that they cannot do surgery until August or so. It is now April...
She is supposed to rest a lot and drink fluids. But she has to go to
classes. She wonders why they have given her no medicine. She plans to
call back her doctor's office / clinic and try to get answers to these
questions. But I told her I would also write in to sci.med and see what I
could find out about why there were so many x-rays and whether it seems
o.k. to wait in line 3 or more months for surgery for something like this
or whether she should be looking elsewhere for her care. She does plan to
get a second opinion, too.
I will pass info on to her. It never hurts to get information

David,
While I disagree strongly with you on the issue of our trusting the government,
I think you have a good idea here. There is danger that, with funding coming
from asset forfeitures, the government could continue to promulgate a bad
product in spite of poor acceptance. Making the product pay its way (as
it must for private ventures) would be a good incentive for quality and
listening to we, the ranters. :)

1,119 | The following is based on copies I was given of some articles published in
Hearing Instruments. I would appreciate any comments about this and other
'new' technology for hearing aids.
The ReSound system was developed on the basis of some research at AT&T and
appears to take a different approach from other aids. It appears to me that
a new 'programmable' aid like the Widex just uses a more flexible (and
programmable) version of the classical approach of amplifying some parts of
the spectrum more than others and adding some compression to try and help
out in 'noisy' situations.
The major difference in the ReSound approach is that it divides the
spectrum into low and high frequencies (splitting point is programmable),
apparently based on the fact that lots of vowel information can be found in
the low frequencies, while the important consonant information
(unfortunately for me) is in the high frequencies. The two bands then are
treated with different compression schemes which are programable. They have
also developed a new fitting algorythm that builds on what they call
'abnormal growth of loudness'.
This latter is interesting and fits my own personal experience, though I
think the phrase is missleading. What appears to be the case is that as you
exceed the minimum threshold for a person with hearing loss, the deficit
becomes progresslively less compared to normals and by the time you reach
the 'too loud' point the sensitivity curves appear to converge. This means
that if you just boost all sound levels, you are overloading at the high
end for people with hearing losses. Hence what you want is progressively
less amplification as the signal get closer to the maximum tolerable point.
You want to boost low volume sounds more than high and do so potentially
differently for the low and high frequency parts of the spectrum (specially
for someone like me who is relatively normal up to 1000 cps and then falls
off a cliff).
Aids with simple compressors don't descriminate between energy in the low
and high frequencies and can therefor 'compress' useful high frequency
information because of high volume of low frequency components.
Particularly impressive was the ReSound performance with whispered speech
and in simulated restaurant noise situations. | 1 |
6,861 | >Remember that they've promised to let a committee of outside experts see

I hope there are some silicon jocks on the committee who can follow
the algorithm through to hardware. While I doubt the NSA would pull
any monkey business on this point -- they have to expect that the
chip will be reverse-engineered sooner or later -- it's an obvious
opportunity to introduce additional holes.
The chip isn't the place to pull the monkey business - you do it in
the key generation, either by having a mathematical backdoor,
or by having the program on the laptop that supposedly generates the
keys also save a copy of S1 and S2 and leak it out somehow,
or by having the program that supposedly puts the official keys
on the chip actually put a *different* key there (VERY hard to detect,
since the escrow agents have to either trust the NSA laptop or
give each other the S* keys, and they still don't know the algorithm.)
Or have the chip-burner at the factory make copies of the keys.
Or whatever. | 1 |

While we are at it, the chip design(s) should be examined and verified
against silicon to insure no trap doors or hidden protocols exist in silicon,
regardless of the security level of the encryption algorithm. There is
no proof that the chip won't squeel and role over for someone with the
proper knowledge to interrogate it via the communications link.
The design examination should be done to the gate level. Also, how does one
verify that what you are looking at is reflected in tapeout, or masks?
The silicon should be examined as well, the design in hand (a clean room
publicly defined clipper chip) can be merged with another design later, or
changed between completion and mask out. There is little proof that what
you are told is in the chip is all that is in the chip.
Put the (verified) masks in escrow, and use them for chip production,
use a third escrow party for programming the chips. | 1 |
