We present experimental and theoretical evidence for the potential of the two-particle spectroscopy to explore the electron-electron interaction in condensed matter. The experiment consists of a single electron impinging onto a clean surface. Two electrons are then emitted simultaneously and their momentum vectors are resolved. The measured energy and angular pair correlations within the pair c...

Energy generation from conventional energy sources, such as oil, coal, and gas, produces adverse environmental pollutants, e [...]

In the last few years, the use of i-vectors along with a generative back-end has become the new standard in speaker recognition. An i-vector is a compact representation of a speaker utterance extracted from a low dimensional total variability subspace. Although current speaker recognition systems achieve very good results in clean training and test conditions, the performance degrades considera...
