Comment Economics? (Score 4, Informative) 342

$4.7B for a nuclear plant. Is it worth it? Will the company get $4.7B worth of use from this asset? If they put it on the market today, what price would they get?

Does this price reflect the cost of building a new nuclear plant today, or is it horribly inflated by the troubled construction history?

The new planed UK Hinkley Point station has (Wikipedia) "estimated construction cost of £18 billion, or £24.5 billion including financing costs." This is two units with combined 3200MW output. Watts Bar II is 1200MW - so the UK is planing on spending more per MW than this plant cost.

In this case, the human doctors only had a written description (I've posted examples in another comment.)

However, the human doctor can use all the information in the description, whereas the app can only do so if it has a box for entering that information. E.g. "Preliminary laboratory studies are notable for a serum ALT of 6498 units/L, total bilirubin of 5.6 mg/dL, and INR of 6.8." (Actual text from one of the cases.) I expect apps aimed at consumers don't have any way to enter this information. (No, I don't know what it means either. I'm not the sort of doctor that helps people.)

I managed to track down the actual text of the cases. TFA was only adding the human doctors to an analysis already done with the aps. The aps paper is and the cases are in the supplementary material ('data supplement')

A 48-year-old woman with a history of migraine headaches presents to the emergency room with altered mental
status over the last several hours. She was found by her husband, earlier in the day, to be acutely disoriented and
increasingly somnolent. On physical examination, she has scleral icterus, mild right upper quadrant tenderness, and
asterixis. Preliminary laboratory studies are notable for a serum ALT of 6498 units/L, total bilirubin of 5.6 mg/dL, and
INR of 6.8. Her husband reports that she has consistently been taking pain medications and started taking additional
500 mg acetaminophen pills several days ago for lower back pain. Further history reveals a medication list with
multiple acetaminophen-containing preparations.

(This one is acute liver failure requiring emergency care).

An 18-month-old toddler presents with 1 week of rhinorrhea, cough, and congestion. Her parents report she is
irritable, sleeping restlessly, and not eating well. Overnight she developed a fever. She attends day care and both
parents smoke. On examination signs are found consistent with a viral respiratory infection including rhinorrhea and
congestion. The toddler appears irritable and apprehensive and has a fever. Otoscopy reveals a bulging,
erythematous tympanic membrane and absent landmarks.

(Acute otitis media - requires 'non-emergent care', i.e. needs professional medical care but is not an emergency)

A 34-year-old woman with no known underlying lung disease 12-day history of cough. She initially had nasal
congestion and a mild sore throat, but now her symptoms are all related to a productive cough without paroxysms.
She denies any sick contacts. On physical examination she is not in respiratory distress and is afebrile with normal
vital signs. No signs of URI are noted. Scattered wheezes are present diffusely on lung auscultation.

(Acute bronchitis, self-care appropriate.)

Comment Re:Haldane (Score 2) 25

Wikipedia was uninformative.
I found a genealogy site with a page for JBS:
Unfortunately, sometimes the links are to a 'private' person, at which point the chain is broken.
JBS had a stepchild but no children of his own. His dad was famous, as were his dad's two brothers and his grandfather. One of those (Richard Burdon Sanderson Haldane) was a viscount and Lord Chancellor, but had no sons. The other, Sir William Stowell Haldane had three sons.

William's sons: Thomas Graeme Nelson Haldane (1897-1981): a 'private' child and a son Richard W Haldane. Richard W has four children, all 'private', three of whom have different surnames so we can guess they were daughters.
Archie Richard Burdon Haldane (1900-1982): two children, but they are listed 'private'
Patrick Haldane (1893-1915): no children listed.

So assuming the listings are accurate (no missing children), it is possible that the Nobel Laureate is descended from JBS's grandfather via JBS's uncle William.
The Laureate's full name is Frederick Duncan Michael Haldane, and he goes by Duncan. This pattern of three first names, using the second, appears a number of times in JBS's family tree.

If you static fired without payload, you'd then have significantly longer between the static test fire and launch (during which something might break) and you'd need to lower the rocket to horizontal to attach the payload and raise it again, again with the potential for breaking something. You'd also have each launch keeping the launch pad occupied for longer.

So, it is a trade-off, and you'd need an intimate knowledge of the rocket and launch operations to know whether SpaceX's choice to test with payload was correct.

A DDOS attack does nothing to attack the integrity or security of the data. The success of a DDOS attack only indirectly calls data safety into question - if they were not able to defend against DDOS, perhaps they're also not good enough to maintain security.

As an aside, I'm currently living in Australia, and the site worked fine for me at about 6pm.
