âThis administration will stand in the way of  Kim âs desire to whitewash their murderous regime with nice photo ops at the Olympics. Perhaps thatâs why they walked away from a meeting or perhaps they were never sincere about sitting down â Ayers said in the statement.
 Kim Jong Un   through  his sister   invited South Korean President Moon Jae-in to Pyongyang to begin talks âsoon.â

Input: Consider Input: Verify if the sentiment of the following document towards the entity Chris Caldwell is Neutral . These primes are exceedingly rare and sporadic  said Chris Caldwell  a professor of mathematics and statistics at the University of Tennessee at Martin  who studies prime numbers and has written a history of the Mersenne primes.
"Finding a prime is not going to change any theorems in mathematics  but this is a type of prime that has been interesting to mathematicians since several centuries before Christ "  Caldwell  said. Even the ancient Greek mathematician Euclid talked about what would later become the Mersenne primes  he said.
 Caldwell  added that the discovery was akin to breaking a land speed record.
The last few Mersenne primes have been closer to each other than the researchers expected   he  said.
The numbers seem to occur sporadically because researchers don't fully understand the pattern they follow   he  said. "So you expect in any process that appears random to have some close groupings of numbers. But  we  didn't expect to find another one so soon after the last one."
"In the long run   we  hope to use these data to predict how often these occur "  he  added.

Output: yes


Input: Consider Input: Verify if the sentiment of the following document towards the entity Louis C.K is Neutral . HBO is severing ties with  Louis C.K.  following a New York Times report that the comedian sexually harassed five women  with allegations spanning back to the late '90s.
The premium cable network has confirmed that it has cut  C.K.  from its Night of Too Many Stars charity telecast  an annual event which raises funds for autism services. HBO also announced that it will be pulling the comedian's stand-up specials and previous TV series â including Lucky Louie â from its on-demand platforms.
â Louis C.K.  will no longer be participating in the Night of Too Many Stars: America Unites for Autism Programs  which will be presented live on HBO on November 18 â an HBO spokesperson said  per Variety. âIn addition  HBO is removing  Louis C.K. âs past projects from its On Demand services.â
Meanwhile  FX Networks â the home of  C.K. 's Emmy-winning comedy Louie  where the showrunner has an overall deal and also executive produces Pamela Adlon's Better Things and Zach Galifianakis' Baskets â issued a statement in response to the report.
âWe are obviously very troubled by the allegations about  Louis C.K.  published in The New York Times today. The network has received no allegations of misconduct by  Louis C.K.  related to any of our 5 shows produced together over the past 8 years. FX Networks and FXP take all necessary actions to protect our employees and thoroughly investigate any allegations of misconduct within our workplace. That said  the matter is currently under review.â

"There is never a place for the behavior detailed in these allegations. As a result  we are giving careful consideration to the timing and release of the film and continuing to review the situation.â
 C.K.  was also scheduled to appear on The Late Show with Stephen Colbert on Thursday night before canceling his appearance  with William H. Macy now set to replace him as a guest  according to the Hollywood Reporter.

Hours after the  C.K.  report broke  an allegation of harassment against Mad Men creator Matthew Weiner also surfaced.
