  1. Re:Crank or coverup on Nuclear Disaster In Japan Could Have Been Mitigated, Say Industry Insiders · · Score: 5, Insightful

    But if somebody tells me a grand total of 13 different backup-generators dotted around the site and five battery-backups might all simultaneously fail due to various reasons he would have an extreremly hard time convincing me.

    Replace "dotted around the site" with "all the in the same basement". And the depletion of all battery backups again was not independent, with a direct causual link both to the upstream generator failure, as well as the disruption to roads and infrastructure which delayed the arrival of additional resources.

    http://www.blog.voximate.com/blog/article/1058/failover-backup-systems-redundant/
    "The risk analysis may calculate the risk of each backup generator failing and then estimate the risk of all of them failing simultaneously by multiplying each generator’s risk of failure together, concluding that the risk of them all failing simultaneously is statistically very, very low. However, such an analysis assumes that the backup generators are all independent systems. As this crisis has demonstrated, the backup generators were NOT independent of each other. Because they were all in the same coast-side, sea level location, they all shared the common vulnerability of being shut down simultaneously by the same tsunami. Therefore, the actual risk of them all failing simultaneously due to a tsunami was equal to the risk of a single one of them failing due to a tsunami. Since all thirteen backup generators in actual fact failed when hit by this tsunami, the risk that each backup generator would fail when hit by a tsunami of this size appears to have been 100%."

    Sounds too good to be true, and no evidence to support it. Recipe for a scam.

    It's getting major buzz in the research community since the group presented preliminary results last year. Science magazine (about as legit as it gets) even titled their write-up "The Quest for Transplantation Tolerance: Have We Finally Sipped from the Cup?", as it truly is considered a holy grail of immunology.

    I guess I thought that was common? Her donor was unrelated, but had a 10/10 match on HLA. That might be the magic. This study lists it working for a HLA mismatched recipient.

    None of the 8 trial participants was a perfect match, ranging from 5/6 down to 1/6 (the article I have access to only lists the */6 system) with 4 organs coming from unrelated donors (the failed transplant case was actually a 3/6 related donor). Also, your daughter's very young age at transplant was a plus.

  5. Re:They Saved The World on Edward Teller: Father of the Hydrogen Bomb · · Score: 1

    China was basically in a civil war at the beginning of WWII.

    Not just at the beginning, but during WWII as well. Chiang-Kai Shek was a staunch anti-Communist, and believed (imho, correctly) the CCP to be as much of a long-term threat as the Japanese. The western powers put him under intense pressure to halt his campaign against the CCP and make an alliance against the Japanese (even then, he only did so after the Xi'an incident). Many historians believe it was the Japanese invasion and ensuing interruption in the civil war that allowed the communists to re-group (in the early stages of the conflict, the KMT very much had the upper hand) and attain eventual victory.

    There are a number of inducible suicide genes (for instance, the HSV1-TK gene, inducible with Acyclovir) that have been developed for this very purpose. I believe the group at U.

    As far as I know, there is nothing specific you can eat that is proven to boost your metabolism.

    Nonsense. A dose of something like, say, 2,4-Dinitrophenol will absolutely increase your metabolic rate. Quite dramatically, and potentially to the point of lethal hyperthermia. On a side note, given DNP's effect on muscular intracellular Ca++ levels, I suspect it could have a demethylating effect similar to that obtained with caffeine used.

    I remain baffled at how companies like Wizards of the Coast think it's acceptable to charge as much for online versions of stuff as they do for the real items (example here is MTG cards).

    WoTC attempted to answer this by allowing MTG:Online players to trade a completed set of online cards for their real physical equivalents (originally for no extra cost, although they have since started tacking on a redemption fee). So in theory you could arbitrage the real and virtual versions.

    I wonder if its effectiveness differs with the language being spoken. Do faster-spoken languages become more stressful and difficult to continue with than slower-spoken ones?

    Well, among languages, Japanese has an especially low information/syllable density (and thus is spoken rapidly). In comparison, languages such as Vietnamese, English and Mandarin Chinese have very high information densities, resulting in lower syllables-per-minute spoken.

    What I don't get is what this device is intended to be useful for if it's only able to sequence 150 million b.p. before wearing out. The article mentions that this is smaller than some human chromosomes, but unless they factored the necessary redundancy into that figure, it's not going to go very far.

    Seeing as how this device uses a protein-based pore complex, I'm not surprised by the limited lifespan. Apparently, they offer a large array of pores to get the ensemble of fragments needed to assemble a complete sequence.

  22. Flash retention times on SSD Latency, Error Rates May Spell Bleak Future · · Score: 1

    Along with error rates, what will happen to retention times as the cell size shrinks?

    Supposedly, flash memories have expected retention times as short as 5-10 years or so (if not refreshed by re-writing), thanks to gradual leakage of the trapped charges they use to record data; this value is expected to drop as flash cells get smaller. I've had gadgets whose firmware mysteriously become corrupted after sitting around for a few years, and sometimes they could be revived by re-flashing them -- I sometimes wonder if this kind of retention problem could have been responsible.

  24. Re:New Sign in the Doctors Office... on Doctors "Fire" Vaccine Refusers · · Score: 1

    1) My wife incurreed less than 150k total, most of it in med school, not undergrad. Its really not that difficult to get most of your undergrad paid for, if you aren't capable of this it means you put no effort into finding grants. There are litterally even grants for people who's parents make too much fucking money, so there is NO excuse for you to exit undergrad with massive debt other than your own

    I am currently in medical school, and am looking at about the same amount of debt (all medical school, undergrad paid off already). That being said, I go to a state school (plus started with some savings, plus have some parental support). The amount of financial support each state gives to their schools varies greatly depending on the state though. Grants are uncommon (since everyone expects doctors will become rich) unless you you meet special criteria -- impoverished background, under-represented minority, or are affiliation with a cultural/ethnic/religious group backed by private donors (also heard of a few set-up by patient advocacy groups and rural communities).

    Private schools can be stupidly expensive (some run 70k+ a year), I wouldn't go to one unless my family was rich.

    3) Doctors get paid for residency, they don't pay someone else for the privledge of doing it. They are working at that point, just watched closer (though less than they should be!)

    Around here I think you can expect 35-50k a year, depending on what program you're in. While this isn't too bad for a family medicine residency that goes 3 years, others can go as much as 7-8 years (but you'll be earning more afterwards).

    4) Bullshit. The cost compared to income is fucking trivial. You can pretend its bad, but my car insurance is more than my wife's malpractice costs, so again trivial compared to income. If you're doctor is paying high malpractice rates then you're intelligent move would be to find a new doctor cause yours has been sued one too many times, which indicates a pattern you might not want to be part of.

    An Ob-Gyn's typical malpractice premium is easily more than a family doc's entire yearly salary. An average general surgeon can expected to be sued every five years. The cost and risk of malpractice varies greatly across specialties; your wife is probably in one of the "safe" specialties (Family practice, Peds, Psych, Derm, a couple of others), or has her malpractice subsidized.
