Two-layer API: • The Browser: C++ API; audio capture, video capture, noise cancellation and noise reduction. Helps browser makers easily implement the Web API. • The Web: Used by the third party developers to develop web based video chat applications. Uses WebRTC, an open framework for real time communications in the browser. • The process of making the illusion of motion and change by rapidly ...

This is the first part of a two-part article that provides in-depth background information and a critical examination of a phenomenon that has importance not only to transpersonal psychology but also to psychology and science more generally–the protracted Marian apparition at Medjugorje. The article presents four perspectives that may advance understanding of what the apparition and related phe...

During the first ascent of the Matterhorn, a remarkable optical effect comprising three crosses surrounded by a great arch was observed by Edward Whymper, the British mountaineer. The authors review previous published explanations of the apparition. There are no photographs, only a woodcut and sketch, so the size of the apparition is not known, and it is not possible to make a definitive conclu...

We present an application of difference equations to number theory by considering the set of linear second-order recursive relations,Un+2( √ R,Q) =RUn+1 −QUn,U0 = 0,U1 = 1, and Vn+2( √ R,Q) =RVn+1 −QVn, V0 = 2,V1 = √ R, where R and Q are relatively prime integers and n∈ {0,1, . . .}. These equations describe the set of extended Lucas sequences, or rather, the Lehmer sequences. We add that the r...
