Long-term stability of variable stepsize approximations of semigroups
This paper is concerned with the stability of rational one-step approximations of C0 semigroups. Particular emphasis is laid on long-term stability bounds. The analysis is based on...

A unified framework for GLRT-based spectrum sensing of signals with covariance matrices with known eigenvalue multiplicities
In this paper, we create a unified framework for spectrum sensing of signals which have covariance matrices with known eigenvalue multiplicities. We derive the generalized likeli...

Gaussian MIMO Multi-Receiver Wiretap Channel
Abstract— We consider the Gaussian multiple-input multipleoutput (MIMO) multi-receiver wiretap channel, and derive the secrecy capacity region of this channel for the most genera...

Experimental Study of Ergodic Learning Curve in Hidden Markov Models
A number of learning machines used in information science are not regular, but rather singular, because they are non-identifiable and their Fisher information matrices are singula...

Enumeration of non-crossing pairings on bit strings
A non-crossing pairing on a bitstring matches 1s and 0s in a manner such that the pairing diagram is nonintersecting. By considering such pairings on arbitrary bitstrings 1n1 0m1 ....
