Input: Consider Input: 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."

Input: Consider Input: What is the sentiment of the following document towards the entity Mark Levin Unloads ? NATIONAL HARBOR  MD â Nationally syndicated radio superstar  Mark Levin  joined SiriusXM hosts Matt Boyle and Amanda House at CPAC on Breitbart News Saturday  praising President Donald Trumpâs actions for advancing conservatism  and making explosive statements about the Left  Obama and his administration  the media  guns  and Democratsâ plans to impeach the president.
 Levin  was speaking to thousands of conservatives who gathered just outside of the nationâs capital at the annual pilgrimage for the conservative movement. Boyle and House were broadcasting live from CPAC  as the âGreat Oneâ sat down with them to reflect on President Trumpâs speech to the conference on Friday  and examining the first year of the Trump administration.
âThis president is so different â  Levin  began. â He  threw out the written speech and  he  said  âLet me talk to you.ââ
â He  connects with you individually â the former Reagan administration senior aide continued  making the observation of the president that  â he  talks like a regular person â as opposed to a polished politician with a team of handlers.
Boyle and Houseâwho respectively are the political editor and deputy political editor of Breitbart Newsâinvited  Levin  to unpack  his  thoughts on how the presidentâs actions stack up with conservative priorities  given  Levin âs pedigree and well-earned reputation as one of the foremost champions of constitutional conservatism. Levin dedicates much of the time on  his  wildly successful radio show holding accountable public officials who stray from conservative priorities.
âWhich is fine by me â  Levin  commented to Boyle and House  âbecause itâs the end result that matters.â
It is no secret that  Levin  does not agree with President Trump on everything. âBut I didnât agree with Reagan on everything â either   Levin  noted  a comparison noteworthy because of the tremendous respect  Levin  has for the nationâs 40th president  under whom  he  served.
 Levin   Boyle  and House then turned to the red-hot issues that are currently dominating the headlines  and explaining what is behind those narratives.
âIf the Democrats take the House  theyâre going to move to impeach this president  to reverse the results of the election â  Levin  claimed. âTheyâve been into this silent coup since the day he was elected. They are furious that he is president of the United States.â
 Levin  called Special Counsel Robert Mueller a âhit manâ and compared Muellerâs investigation to a âmob operation.â
âThis is a grotesque miscarriage of justice â  Levin  insists. âSomething about this stinks to high heaven.â
 Levin  said that  he  noticed a pattern  relying upon  his  experience as a top Justice Department official.  He  recalled the moment during the 2016 election when  he  concluded  âweâve got domestic surveillance of Trump World.â
 Levin  insists that this was âpolitical domestic surveillance â and that a host of characters  from the Obama White House  to top officials in the Obama-Lynch Justice Department  to leaders at the FBI  must have known about it when it was happening.
There are âhardcore anti-constitutional progressive leftistsâ who are out to get President Trump  and the entire conservative agenda would be endangered if the presidentâs enemies succeed   Levin  warned.
