This seems amazing.
Along with a crew of technologists and scientists, Jorge Soto is developing a simple, noninvasive, open-source test that looks for early signs of multiple forms of cancer. Onstage at TEDGlobal 2014, he demonstrates a working prototype of the mobile platform for the first time.

United attempting to force me to buy travel insurance? I have had one bad experience after another with this company. Unfortunately they charged me an extra $600 on my last flight and the only way to recuperate the extra fees is to purchase my next flight through them. Yuck.

Using my estimation data I was able to calculate your proportion of fatal cases/proportion of suspected for different differences in days. You can insert the following command at the end of my R code:

From the post you commented on:
http://www.econometricsbysimulation.com/2014/09/12-millions-deaths-by-ebola-projected.html

esub <- ebolahat[1:160,]
mort <- c()
for (i in 1:25)
  mort[i] <- mean(esub[(1:i), 'Edea']/esub[(1+nrow(esub)-(1:i)), 'Esus'])
cbind(mort)

Which gives for each different [day] lag the death #/suspect #.
mort
[1,] 0.6090483
[2,] 0.6209797
[3,] 0.6331601
[4,] 0.6456401
[5,] 0.6583813
[6,] 0.6713897
[7,] 0.6846719
[8,] 0.6982350
[9,] 0.7120844
[10,] 0.7262256
[11,] 0.7406678
[12,] 0.7553701
[13,] 0.7703834
[14,] 0.7857164
[15,] 0.8013752
[16,] 0.8173688
[17,] 0.8337024
[18,] 0.8503376
[19,] 0.8673291
[20,] 0.8846860
[21,] 0.9024124
[22,] 0.9204725
[23,] 0.9389198
[24,] 0.9577148
[25,] 0.9769171

You can see after 15 days or so the death rate rises to 80%. That said, I am highly doubtful of this statistic since I think the suspected cases is probably vastly under-reported while deaths you would think should be easier to identify.

So I had a kind of disturbing experience at this hotel. Recently I was there attending an academic conference hosted at the hotel. At the end of the conference I was waiting around for my wife to pick me up. It was raining heavily outside and I was walking back and forth not certain when my wife would pick me up as well as not sure which direction she was coming from (and getting a few extra steps on my fitbit while I was at it) when one of the bellhops (red shirt, ear piece etc.) started following me. This older and short guy kind of just started following me, keeping just a few feet away. He made me extremely uncomfortable. Fortunately my wife pulled up just as I was preparing to confront him. Yet my skin continued to crawl a bit and so I called the manager of the hotel to report the incident and she kind of brushed me off at first implying that the guy did not work for the hotel then dismissing my concerns. But it was obvious with his interactions with the other employees and his shared uniform that he did work for the hotel. I write this complaint as a bit of a flag for weird behavior going on at the Merriot and as a mention of the kind of treatment you are likely to expect from management when issues arise. I would hate for this employee to be penalized since I am sure his actions must have been supervised by some manager. Furthermore, by the general blanket denial of the management, I am pretty sure that this is not such a surprising situation. So, who knows…shrug. On a side note, the layout of the hotel is disappointing when compared to other establishments of its caliber. I would define the decor as say mid-1970s. I guess I am not so familiar with Merriots, so maybe it is typical. But compared to the Hyatts and Sheratons I have been in, it definitely seemed a sad comparison.

I had my groomsmen outfitted by Men's Warehouse. It it hard to imagine the number of things they got wrong or failed to supply altogether despite having fittings and reservations months in advance. My fiance and I spent hours comparing and painstakingly selecting suits, vests, ties, and other combinations. Somehow, when we went to pick up the actual order though there was literally next to nothing which matched our specifications. It was absolutely bizarre, like the company had fulfilled the wrong order. We struggled to find suits, shirts, and pants that fit the physical requirements of my groomsmen let alone fulfill our specific order. Though my wedding was on Monday and we picked up our order and noticed the problem on a Friday, Men's Warehouse was incredibly unhelpful, claiming their warehouse was closed on weekends and little could or would be done to rectify the situation. Ultimately, I ended up waiting the hours leading up to my wedding for my jacket which I was able to to pick up at the Men's Warehouse at the last minute. I don't really understand how such a business can be so unprofessional and still charge such exorbitant rates.

Worse bank in America. This bank is really bad. They will not stop charging fees just for having money in the account. My wife and I were abroad for a year and we had a bill being automatically drafted from the account. At some point the account balance dropped below 750 and ever since then they started charging us the 11.99 each month. The total cost has been over $100. In addition to this, their online system only allows for statements for up to six months (which has also presented problems). The bank manager also vouched for our selecting a property manager Maureen Tipple after which she fraudulantly wrote checks out of our account for work that was never done. When we attempted to place a hold on a check that Maureen wrote the bank charged us the 25 dollar holding fee but still let the check go through. And my wife just tried cancelling her account with them and after she followed their instructions on how to cancel her account without additional fees, the representative still tried to charge her 11.99 for not having sufficient funds in the account. Anyways, I say 'worse bank in America' not because I know it is but because I have had account with many other banks (I like sampling many different options) and I can say with certainty that this bank has the worse policies of any bank I have used. The other banks I have had accounts with without major complaints are: Rocky Mountain Federal Credit Union MSU Federal Credit Union Chase Wells Fargo First Arkansas Bank and Trust First Interstate Lake Trust Credit Union Charles Schwab

They are great. Took my two cats and my dog there on various occasions. Every time they have taken care of the needs on hand at a very reasonable price. The staff are also very friendly.

This is a good bank with bankers who are thoughtful and helpful. I started using them because of the 100 cash bonus for openning an account with them and have been consistently happy with our services with them for the last 5 years. Normally when I leave an area I find a new local bank. I have moved away and kept using this bank.

DON"T STAY HERE IF YOU VALUE YOUR LIFE!! My wife and I arrived on a lightly drizzling day at Sunset Manor after making a reservation through Expedia. Upon approaching the hotel it is not clear where even the front desk is since the placement of the sign is ambiguous. I slipped to the left of the entry thinking that one part of the hotel was the reception which turned out to be an exposed brick stairwell leading up to the rooms. Upon discovering my confusion I attempted to walk down the stairwell. However, the stairs were exceedingly slippery and I fell and kept falling. My laptop which I was carrying in my hand because it had my reservation information on it slipped out of my hand and clattered down as many stairs. After waiting for the shock and the pain to subside I got back up to my feet. I examined the stair case and found that there is no reasonable way for anybody to expect the stairs to be as dangerous as they were. There is a railing on one side of the staircase but it is wide and made from the same slick bricks as the stairs. Thus even if I could have reached the railing it likely would have provided very little assistance. Eventually, bleeding and in great pain I made it to the front desk to find that the hotel had overbooked. We would need to stay at a hotel up the road. The night-shift man on duty at the time who had seen the accident through the cameras and now saw me bloody and bruised told me, ‘it is very common for people to fall’. So he gave me some ice apparently he had on hand for such events and showed us to the next hotel which was basically a rundown backpackers in which my wife and I had to sleep in separate beds. The next day I talked with the manager on duty and she said that, ‘people always fall here. I fell just the other day’. She made no effort to compensate us for not having our room available nor did she make any effort to make any effort to compensate us for the injuries I received. After mentioning the situation multiple times on both that day and the next I finally requested to talk with the owner who was all apologies. He said he had owned the place for 10 YEARS and this was the first incident that anybody had fallen. He was very sorry for my broken computer and my injuries and that all I needed to do was write up the incident in an email and send it to him and he would forward it on to his insurance. Well, I wrote up the incident and sent it to him two weeks ago and I have not heard anything back. I am pretty sure I am not ever to hear anything back. Anyways, looking into legal remedies. Just wanted to put this out there. I am a healthy athletic 31 year old who exercises and has good balance. I cannot remember falling for any reason in the last ten years. Yet this stairwell was clearly poorly designed, with little traction and a high susceptibility to precipitation. Talking with the owner and management made it clear to me that there was no intention of improving the situation.

Maureen Tippel and Greg Kraft (Kraft Construction) are frauds. They managed one home my girlfriend and I for the last year. They blatantly committed fraud on multiple occasions in order to capture all of our rental income. Over the last year we had full occupancy and took in $8,000 and they with their fraudulent "repairs" turned around and took $7,950. They said that there was this thing or that thing that needed to be done. But when I finally made the time to investigate all of these "repairs" nearly half of them had never even been done. And these are major repairs like roof replacements! When confronted they said "oh, it was done", you just don't know what you are talking about. When brought photos they said stuff like, "he hired this other guy and I can't believe he did not do the work! I will take care of that!" They claimed that they would be sure that the work would get done, yet they have not made the repairs and they have refused to return the money. Maureen and Greg sat down with me near their abrupt termination. Anxiously I went to the bathroom and left a tape recorder at the table. As I was at the bathroom they openly discussed how Maureen was going to control the situation in order to defraud us (my girlfriend was out of town). At that meeting they made promises like fixing the repairs that were not done, reimbursing us for repairs which were "billed to us but actually at a different home", and directly returning a trivial amount of money. They literally fabricated thousands of dollars of repairs that were obviously never done and the only thing they have done to "make things right" is to write a $50 check from some other property owners account.
