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.

Verify if the sentiment of the following document towards the entity Brexit is Neutral . The financial services sector  which accounts for about 12 percent of Britainâs economic output and pays more tax than any other industry  potentially has a lot to lose from the end of unfettered access to the EUâs post-Brexit market of 440 million people.
But it is particularly vulnerable to  a Brexit shock   because about a third of the transactions which take place on  its  exchanges and in  its  trading rooms involve clients in the EU.
This has led some politicians and economists to predict London will lose its pre-eminence as a financial center after Brexit  although supporters of leaving the EU say Britain will benefit over the long term by being able to set its own rules.
According to Savills  commercial property prices in the City of London have dropped more since the Brexit vote in June 2016 than at any point since 2009  the last year of the global financial crisis.
So far  Brexit seems to be having no impact here. The number of venues  such as bars and restaurants  applying for new licenses to sell alcohol in the City of London in the first eight months of 2017 is at a record high  data from the municipal local authority that runs the district shows.
âBusinesses are naturally hesitant to plan and execute growth hires due to the uncertainty around  Brexit  â said Hakan Enver  a director at Morgan McKinley.
The findings suggest that the first wave of job losses from  Brexit  may be at the lower end of estimates by industry lobby groups and firms  which could mean London will keep its place as the continentâs top finance center  at least in the short term.

Verify if the sentiment of the following document towards the entity Jackie Selebi is Positive . South Africa's former police chief and ex-president of Interpol Jackie Selebi was convicted Friday of corruption for accepting bribes from organised crime.
 Selebi had denied the charges against him  which he said were part of a broader political conspiracy that reached to the top levels of government.
 The trial laid out his startling links with the criminal underworld  in particular with convicted drug smuggler Glenn Agliotti who was accused of giving him cash and luxury gifts.
 Selebi was accused of taking bribes from Agliotti totalling more than 1.2 million rand (166 000 dollars  122 000 euros) between 2000 and 2005.
 What finally emerged was a picture of Agliotti  who was also accused in the murder of a local mining magnate  indulging Selebi's fondness for designer clothing  which the police chief rewarded by feeding Agliotti inside information.
 While in office  Selebi acknowledged his friendship with Agliotti saying "Glenn Agliotti is my friend  finish and klaar (end of story)."
 It was Agliotti's drugs conviction that lifted the lid on Selebi's activities  sparking a lengthy investigation into his life.
 His first arrest warrant was issued in September 2007 but he was not charged  reportedly due to protection by then-president Thabo Mbeki.
 On January 11  2008  he was charged with corruption and defeating the ends of justice due to his friendship with Agliotti.
