Today the collaboration for the LHCb experiment at CERN's Large Hadron Colliderannounced the discovery of two new particles in the baryon family. The particles, known as the Xi_b'- and Xi_b*-, were predicted to exist by the quark model but had never been seen before. A related particle, the Xi_b*0, was found by the CMS experiment at CERN in 2012. The LHCb collaboration submitted a paper reporting the finding to Physical Review Letters.
Like the well-known protons that the LHC accelerates, the new particles are baryons made from three quarks bound together by the strong force. The types of quarks are different, though: the new X_ib particles both contain one beauty (b), one strange (s), and one down (d) quark. Thanks to the heavyweight b quarks, they are more than six times as massive as the proton. But the particles are more than just the sum of their parts: their mass also depends on how they are configured. Each of the quarks has an attribute called "spin". In the Xi_b'- state, the spins of the two lighter quarks point in the opposite direction to the b quark, whereas in the Xi_b*- state they are aligned.
British Airways will offer wi-fi internet access on its short-haul flights from 2017, its owner IAG has announced.
According to a report in Buzzfeed, former Twitter employees have said Dick Costolo filtered tweets during the #AskPOTUS townhall, the President's Q&A session in May last year. Costolo reportedly asked for a new algorithm that could filter abusive tweets, but didn't stop there. He also asked the media partnerships team to manually censor tweets in case the algorithm was inconsistent
After months of Apple rumours, news about the Apple iPhone 7 models are finally beginning to clear and today we have the first solid evidence from a credible source which claims that there are not two, but three iPhone 7 models planned this year.
The deal will be funded by Softbank's own cash reserves and a long term loan from Japan's Mizuho Bank.Softbank is one of the world's biggest technology companies and is run by its founder, Japanese entrepreneur Masayoshi Son.It has previously acquired Vodafone's Japanese operations and the US telecoms company Sprint. The $20bn deal was the biggest foreign acquisition by a Japanese firm at the time.
"These are possible foci for attacks that could have a devastating impact on users of the end product, and economic impact in the form of recalls and lawsuits," said Nikhil Gupta, noted materials researcher and an associate professor of mechanical engineering at the New York University Tandon School of Engineering.
Once upon a time, Snapchat was a simple app. You took a picture, you sent it to a friend, and it disappeared shortly after.
The vehicle-a 3D-printed minibus called "Olli" capable of carrying 12 people-was unveiled by Arizona-based startup Local Motors outside the US capital city Washington.
This illustration depicts the view from outside of a rapidly-accreting black hole. The bright light toward the center represents the super-heating of gas as it falls onto the black hole. Emanating from the center is a jet of accelerated particles moving near the speed of light. Surrounding the black hold is cool, clumpy gas and dust, which are falling inwards and will eventually join the material accreting onto the black hole.
"Health" and "illness" are contrasting word groups. They can be moved to physical or in mental context. Lots of internet marketers that physical exercise done on a normal basis keeps us healthy. Mental exercise also keeps us mentally healthy. Similar to after doing doing exercises we need rest, after mental exercise the mind also needs rest. But we hear the phrase "physical rest" oftentimes. The term "mental rest" is rarely chosen
A service-oriented architecture is essentially a collection of services. These services communicate with each other. The communication can involve either simple data passing or it could involve two or more services coordinating some activity. Some means of connecting services to each other is needed. Service-oriented architectures are not a new thing. The first service-oriented architecture for many people in the past was with the use DCOM or Object Request Brokers (ORBs) based on the CORBA specification. For more on DCOM and CORBA
