[EX Q]: 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."

[EX Q]: What is the sentiment of the following document towards the entity Trump Be Trump ? Breitbart News has been provided with an exclusive preview of and excerpt from the new book   Let  Trump  Be  Trump   by Corey Lewandowski and David Bossie  published by Center Street and available on December 5  2017.
From Let  Trump  Be Trump:
âI want you to know I have the greatest air force in the world â  Trump  began  unprompted  in Coreyâs first meeting with the candidate. âIâve got a 757  Iâve got a Citation X. And Iâve got three helicopters.â Corey sat there with a half smile on his face  not knowing quite how to respond.
When  Donald Trump  listed the aircraft  he  had during Coreyâs job interview  Corey shrugged it off as a random boast. But  Trump  wasnât boasting.  He  was pointing out the military equipment  he  had for the war ahead. A candidate with a jet has a formidable advantage over rivals without one. A candidate with an air force was going to be tough to beat.
When you flew with  Trump   you flew first class times ten. Except  that is  when it came time to eat.
The first time Dave told his wife Susan that he was going to be on Trump Force One  she asked him to take some photos of what they served him to eat on the plane. She had read somewhere that  Mr. Trump  had a personal chef who traveled with  him . When dinner came on the flight  Dave pulled out his BlackBerry and snapped a picture of the bag of McDonaldâs hamburgers and unopened package of Oreo cookies and emailed it to Susan.
On Trump Force One there were four major food groups: McDonaldâs  Kentucky Fried Chicken  pizza  and Diet Coke. There were also ancillary groups  including Vienna Fingers and the ubiquitous Oreo  before the boycott (after it was Hydrox). The reason the package of Oreos was unopened was because  Mr. Trump  would never eat from a previously opened package. If youâve seen the Seinfeld episode in which George double-dips  his  chip  you have a pretty good idea of the bossâs reasoning. Packages of cookies  along with small airliner-size bags of pretzels and potato chips  filled the planeâs cupboards. An army might march on its stomach  but Trumpâs team flew on junk food. And those snacks would have to sustain us during long flights and even longer days.
The candidate would hardly ever eat lunch and would eat dinner only after he finished the last event of the day. Weâd be in the jet or on the road from seven or eight a.m.  make however many scheduled stops we had  and after the last one  perhaps around nine p.m.   Mr. Trump  would clap  his  hands and say  âLetâs eat!â And the food needed to be hot and ready for  him . Some of the time  especially when  he  was pleased with  his  performance at a rally or event   he âd say  âDo you think I deserve a malted today? I think I deserve one.â  Trump   a city kid  grew up drinking malteds  so thatâs what he always called a milkshake. Whatever you want to call it  it better be there and it better still be thick.
When traveling in the air with the boss  you also learned pretty quickly to like Elton John.  Donald Trump  really likes Elton John. Anthony âthe Moochâ Scaramucci got in all sorts of hot waterâwhich is not at all an unfamiliar position for himâwhen he told an interviewer that Elton John would play at President Trumpâs inaugural. It had been wishful thinking on Moochâs part  probably because heâd been on the plane when the boss had âTiny Dancerâ or âRocket Manâ playing as loud as the concert-level speakers could bring it. Weâre telling you  when the boss cranks up Elton  you canât hear yourself think. The music is loud enough to rattle your brain.

[EX Q]: What is the sentiment of the following document towards the entity Clinton ? President Donald Trump's critics are arguing that GOP calls for the Justice Department to investigate  Hillary Clinton  and Democrats' ties to Russia are an effort to distract from the real Russia investigation  into potential Trump-Russia collusion.
Ever since Watergate  the mantra of all major corruption investigations has been to "follow the money." Well  Americans of all political stripes should be outraged by the fact that both Democrats and Republicans in Washington are up to their eyeballs in Kremlin cash. Russian money found its way into the pockets of not only Trump advisers like Paul Manafort and Rick Gates â who were recently indicted by special counsel Robert Mueller âbut also Democratic power lobbyist Tony Podesta   Bill Clinton  and the Clinton Foundation.
This should suggest to objective observers that Russia was using its money to influence both sides in order to advance the Kremlin's interests. And it means that any full and impartial investigation of Russia's efforts to influence our political process needs to follow the Russian money flowing into the coffers of  the Clintons    their  foundation and  their  top associates.
The New York Times reported in 2015 that "shortly after the Russians announced their intention to acquire a majority stake in Uranium One   [former President Bill] Clinton  received $500 000 for a Moscow speech from a Russian investment bank with links to the Kremlin that was promoting Uranium One stock." In total  $145 million went to  the Clinton Foundation  from interests linked to Uranium One  which was acquired by the Russian government nuclear agency Rosatum.
Think that was just a coincidence? As former federal prosecutor Andy McCarthy points out  the Uranium One deal is not a national security scandal  it is a corruption scandal involving " Clinton  family self-dealing." Ask yourself: How many half-a-million-dollar speeches has  Bill Clinton  given to Kremlin-linked banks since  Hillary Clinton  was defeated? How much Russian money is flowing into  the Clinton Foundation 's coffers today? If Donald Trump had given a $500 000 speech paid for by a Kremlin bank  and his private foundation had accepted $145 million from Vladimir Putin-linked oligarchs and their Western business partners  do you think that his critics would be insisting there was nothing to see here?
A look at  Hillary Clinton 's time as first lady  U.S. senator  secretary of state and a Democratic candidate for president.
We should all be deeply concerned by how much Russian cash was sloshing around Washington  and how much of it found its way into  the bank accounts of the Clintons  and those around  them . And we should all  Democrats and Republicans alike  want to get to the bottom of it.
As Americans  it goes against our sensibilities to encourage the Justice Department of one party to investigate the vanquished candidate of the other party. But does the fact that  Clinton  lost mean Americans don't deserve to know the full extent of Russia's efforts to influence our political process?
None of this absolves the Trump campaign or calls into question the intelligence community's conclusion that "Putin and the Russian Government aspired to help ... Trump's election chances." But it does underscore that the Russians were smart in what the intelligence community calls their efforts to "undermine public faith in the US democratic process." They played both sides  and in so doing preyed on the singular weakness of the Clintons and those around them â greed.
Any impartial investigation of Russia's efforts to meddle in our democratic process needs to include a full inquiry of the Russian money flowing into  Clinton  world. Such an inquiry is not a distraction. It is critical to restoring public faith in American democracy.
Trump's obsession with  Hillary Clinton  should scare everyone
A Bill Clinton 'reckoning' for Democrats? Don't hold your breath.
