Third derivatives of the integrable part of an asteroid Hamiltonian [PDF]
Serbian Astronomical Journal, 2007 To apply the theorem of Nekhoroshev (1977) to asteroids, one first has to check whether a necessary geometrical condition is fulfilled: either convexity, or quasi-convexity, or only a 3-jet non-degeneracy.

Optical Chaos Generation and Applications
Advanced Photonics Research, EarlyView.This review comprehensively examines optical chaos generation via feedback, injection, and optoelectronic methods, emphasizing bandwidth enhancement and time‐delay suppression. Applications include chaos‐synchronized secure communication, physical random number generation, chaotic lidar for cm‐level detection, distributed fiber sensing, and terahertz ...

TITIUS-BODE`S Relation and 55 Cancri [PDF]
Journal of Astronomy and Space Sciences, 2008 Two kinds of important issues on Titius-Bode`s relation have been discussed up to now: one is if there is a simple mathematical relation between distances of natural bodies orbiting a central body, and the other is if there is any physical basis for such
