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 Robert Mueller ? Itâs not too late for Congress to create such a commission  because the American public has lost faith in the objectivity of congressional committees. Many Americans  though certainly not all  have also lost faith in the investigation currently being conducted by  Special Counsel Robert Mueller .
 Mueller himself  continues to be held in high regard by most Americans  but many of  his  underlings are widely regarded as partisan.
 Mueller  did the right thing by reassigning FBI agent Peter Strozk after  his  anti-Trump communications with  his  girlfriend were revealed. But Strozk should have recused himself from the Clinton investigation based on his own knowledge of his bias against Trump.
When a president or a presidential candidate is being investigated  everyone involved in the investigation must be âCaesarâs wifeâ â above reproach. Several of  Mueller âs appointees do not pass that test.

What is the sentiment of the following document towards the entity Theresa May ? British Prime Minister Theresa May  has said that  her  government is "proving the doubters wrong" after European Union leaders agreed that Brexit negotiations can finally move on to their next phase in the new year.
Leaders of the other 27 EU nations gave a boost to  May  on Friday when they declared that talks over Britain's exit can proceed to the issues of transition and future relations.
Writing in two Sunday newspapers   May  also struck a defiant note and said  her  Brexit plans won't be "derailed" by anti-Brexit campaigners.
May  who is already struggling to maintain  her  authority amid the fractious exit process  suffered a significant political defeat in Parliament on Wednesday when the House of Commons voted to give lawmakers the final say on any Brexit agreement.
