Phase space structure and fractal trajectories in 1½ degree of freedom Hamiltonian systems whose time dependence is quasiperiodic
Phase space structure fractal trajectories freedom Hamiltonian systems time dependence
2009/11/13
We consider particle motion in nonautonomous 1 degree of freedom Hamiltonian systems for which H(p,q,t) depends on N periodic functions of t with incommensurable frequencies. It is shown that in near-...
The time dependence of molecular iodine emission from Laminaria digitata
molecular iodine emission Laminaria digitata
2009/3/13
We present the first in situ detection of molecular iodine emitted from the brown macroalga Laminaria digitata under natural stress conditions. We show that the release of I2 occurs in short, strong b...
An Eddy-Resolving Numerical Model of the Ventilated Thermocline：Time Dependence
Eddy-Resolving Numerical Model Ventilated Thermocline Time Dependence
2009/1/7
A primitive equation, eddy-resolving numerical model is used to study the inherent time scales of variability in the subtropical ocean, assuming temporally constant surface forcing. Three primary scal...
The time dependence of quantum evanescent waves generated by a point source with an infinite
or a limited frequency band is analyzed. The evanescent wave is characterized by a forerunner
(transient)...
