What is the sentiment of the following document towards the entity Joachim Frank ? The 2017 Nobel Prize in chemistry has been awarded to  researchers Jacques Dubochet  Joachim Frank and Richard Henderson  for  their  work that developed cryo-electron microscopy  which the Royal Swedish Academy of Sciences says "both simplifies and improves the imaging of biomolecules."
Speaking to the prize committee by phone Wednesday morning   Frank  said  he  had thought the chance of  him  winning the prestigious honor was "minuscule."
 He  added that cryo-electron microscopy "is about to completely transform structural biology " saying the technology is being taken up by a new generation of medical researchers.
Dubochet is affiliated with the University of Lausanne  in Switzerland;  Frank  is affiliated with Columbia University in New York; Henderson is affiliated with the MRC Laboratory of Molecular Biology in Cambridge  U.K.
"Electron microscopes were long believed to only be suitable for imaging dead matter  because the powerful electron beam destroys biological material. But in 1990  Richard Henderson succeeded in using an electron microscope to generate a three-dimensional image of a protein at atomic resolution. This breakthrough proved the technology's potential. " Joachim Frank  made the technology generally applicable. Between 1975 and 1986  he  developed an image processing method in which the electron microscope's fuzzy twodimensional images are analysed and merged to reveal a sharp three-dimensional structure. "Jacques Dubochet added water to electron microscopy. Liquid water evaporates in the electron microscope's vacuum  which makes the biomolecules collapse. In the early 1980s  Dubochet succeeded in vitrifying water â  he  cooled water so rapidly that it solidified in its liquid form around a biological sample  allowing the biomolecules to retain their natural shape even in a vacuum."

What is the sentiment of the following document towards the entity Bill Cosby ? Bill Cosby   seen here at an August court appearance  is set for a retrial on sexual assault charges in April  after his first trial last spring ended in a hung jury. (Matt Rourke/AP)
The prosecutor in the  Bill Cosby  case asked a Pennsylvania judge to allow testimony from 19 alleged prior victims of the entertainer  whose retrial on sex assault charges is set to begin April 2.
The request is the first public indication of the shape and parameters of the prosecution case  and it represents a significant expansion of the government’s effort to portray  Cosby  as a serial predator. When  Cosby  was tried in June  prosecutors sought to include testimony from just 13 women who said they had been assaulted by the comic legend.
But it remains to be seen how this latest move by prosecutors will play out: Last year’s effort by prosecutors to introduce so-called “prior bad acts” testimony was largely unsuccessful  as the judge allowed only one of the 13 to appear at  Cosby ’s trial  which ended with a hung jury.
[What’s next for the Bill Cosby sex-assault case?]
In their request Thursday  prosecutors said that  Cosby  “has spent a lifetime entertaining audiences in front of the camera. Off camera  he has followed and  indeed mastered  a more nefarious script — a victimizing sexual script. . . . To satiate his desire  he has engaged  over the course of a lifetime  in a pattern of serial sexual abuse.”

 Cosby  faces felony charges for allegedly drugging and sexually assaulting Andrea Constand  a former Temple University employee  at  his  suburban Philadelphia estate in 2004.  Cosby   now 80  has denied sexually assaulting women.

What is the sentiment of the following document towards the entity Lindsey Vonn ? And  Shiffrin  might one day pass them both.
A month shy of her 23rd birthday   Shiffrin  already has 41 World Cup wins. But most of those have been in the tech events  meaning she and Vonn rarely crossed paths on the World Cup circuit. That changed this season  as  Shiffrin  began adding speed events to her schedule.
With  Shiffrin  hoping to do all five events in Pyeongchang  the idea of seeing  her  and Vonn  33  go head-to-head with Olympic gold on the line was one of the most tantalizing storylines of the Games. But the fireworks keep fizzling.
First was Saturday’s Super-G  which  Shiffrin  dropped after racing the giant slalom and slalom the two previous days. (And taking gold in the GS  for those keeping track.) Now it’s the downhill  which  Shiffrin  is skipping to focus on the Alpine combined that was moved from Friday to Thursday.
Then again  it feels right that  Vonn  gets the spotlight to  herself  in the race that's defined  her .
For all that  she ’s achieved  Vonn's luck at the Olympics has been stunningly bad.  She  was eighth in the downhill in Turin  two days after  she  had to be airlifted to a hospital following a scary crash in training.  She  missed Sochi after reinjuring  her  knee about six weeks before the Games.
Even in Vancouver  where  she  won gold in the downhill and bronze in the Super-G   she  was skiing with a badly bruised shin.
With one last chance to have the Olympics  she  wants   Vonn  has poured every bit of  herself  into these Games. The death of  her  beloved grandfather  Don Kildow  on Nov. 1 only hardened  her  resolve.
“This time I have a more important mission; win for my late Grandpa  ” Vonn  said in an Instagram post the night before the Super-G. “He will be watching from the best seat in the house  hopefully looking out for me and guiding me down the mountain.”
 Vonn  didn’t win the Super-G  tying for sixth after making a mistake in the last turn. But  she  was upbeat afterward  knowing  her  best race was still in front of  her .
“In general  this season  I feel like I’ve been much better in downhill than Super-G ”  Vonn  said Saturday. “And this hill  it suits me really well for downhill."
 She ’s backed that up so far.  She  had the fastest time in Sunday’s training run. Despite backing off a bit Monday   she  still finished third  .35 seconds behind Austria’s Stephanie Venier.
“I’m not looking to do anything special here in the training runs ”  Vonn  said Monday. “I just want to get a feeling for the line. I’m trying some different skis every day to seeing what’s running. But  in general  I’m really happy.”
It is only a matter of days before  Vonn ’s Olympic career is over  and  she  can see the finish line ahead. But as  she ’s done for the better part of two decades now   she  will not let up until  she ’s crossed it  pushing hard until the very end.
“You can’t get too sentimental right now because I still have to race  I still have to be focused ”  she  said. “Afterwards I’ll do some reflecting.”
And savor that one last race that belonged all to  her .
