Efficient searches of small signals across two-channel noisy data: a challenge in Big Data observations
Maryam Aghaei Abchouyeh, Maurice H. P. M. van Putten
Searching for novel small signals in noisy data is preferably pursued by correlation in two or more independently operating channels. Signals of potential interest exist in tails b…

A non-hermitean momentum operator for the particle in a box
Seyong Kim, Alexander Rothkopf
We construct a discrete non-hermitean momentum operator, which implements faithfully the non self-adjoint nature of momentum for a particle in a box. Its eigenfunctions are strictl…
