Analog Frequency Tracking Filter
Advances in Electrical and Computer Engineering, 2013 This paper propose a new type of analog adaptive filter derived as a generalization of the concept of matched filter. We conceive such a filter to track the instantaneous frequency of frequency modulated signals.

Entanglement generation and evolution in open quantum systems [PDF]
, 2009 In the framework of the theory of open systems based on completely positive quantum dynamical semigroups, we study the continuous variable entanglement for a system consisting of two independent harmonic oscillators interacting with a general environment.

Are species-area relationships from entire archipelagos congruent with those of their constituent islands? [PDF]
, 2010 Copyright © 2010 Blackwell Publishing Ltd.AIM To establish the extent to which archipelagos follow the same species–area relationship as their constituent islands and to explore the factors that may explain departures from the relationship.

Asymptotic entanglement in open quantum systems
, 2008 In the framework of the theory of open systems based on completely positive quantum dynamical semigroups, we solve in the asymptotic long-time regime the master equation for two independent harmonic oscillators interacting with an environment.
