The Physical Parameters and Excitation of Jets and Knots in PNe
D. R. Goncalves, A. Mampaso, R. M. L. Corradi +1
We are carrying out a study of the physical parameters and excitation of low-ionization structures (LIS) in planetary nebulae (PNe). Since the optical morphology and kinematics of…
Control of Hamiltonian chaos as a possible tool to control anomalous transport in fusion plasmas
G. Ciraolo, F. Briolle, C. Chandre +6
It is shown that a relevant control of Hamiltonian chaos is possible through suitable small perturbations whose form can be explicitly computed. In particular, it is possible to co…
An Analysis of a Circadian Model Using The Small-Gain Approach to Monotone Systems
David Angeli, Eduardo D. Sontag
In this note, we show how certain properties of Goldbeter's 1995 model for circadian oscillations can be proved mathematically, using techniques from the recently developed theory…
Control of chaos in Hamiltonian systems
G. Ciraolo, C. Chandre, R. Lima +2
We present a technique to control chaos in Hamiltonian systems which are close to integrable. By adding a small and simple control term to the perturbation, the system becomes more…
Simultaneity, radar 4-coordinates and the 3+1 point of view about accelerated observers in special relativity
D. Alba, L. Lusanna
After a review of the 1+3 point of view on non-inertial observers and of the problems of rotating reference frames, we underline that was is lacking in their treatment is a good gl…
In the search for the low-complexity sequences in prokaryotic and eukaryotic genomes: how to derive a coherent picture from global and local entropy measures
Claudia Acquisti, Paolo Allegrini, Patrizia Bogani +6
We investigate on a possible way to connect the presence of Low-Complexity Sequences (LCS) in DNA genomes and the nonstationary properties of base correlations. Under the hypothesi…
