Putting sharks on the map: A global standard for improving shark area-based conservation

open access: yesFrontiers in Marine Science, 2022
Area-based conservation is essential to safeguard declining biodiversity. Several approaches have been developed for identifying networks of globally important areas based on the delineation of sites or seascapes of importance for various elements of ...

Generalized Horseshoes in the Standard Mapping [PDF]

open access: yesProgress of Theoretical Physics, 2005
Summary: There exist \((2n+1)\)-fold horseshoes with topological entropy \(\ln (2n+1)\) for \(n \geq 1\) in the standard mapping for appropriate parameter values. These generalized horseshoes form the hierarchical structure in the phase space. The dynamical order relation among the doubly reversible periodic orbits appearing through a saddle node ...

Oscillatory Orbits in the Standard Mapping [PDF]

open access: yesProgress of Theoretical Physics, 2004
Summary: Oscillatory motion is unbounded but returns infinitely many times to finite positions. The existence of this motion has been predicted and proved to exist in the three-body problem. In the present paper, we prove its existence in the standard mapping, using orbits of the accelerator mode and non-Birkhoff periodic orbits. This motion appears as

Standardized Map of Iodine Status in Europe [PDF]

open access: yesThyroid®, 2020
Background: Knowledge about the population's iodine status is important, because it allows adjustment of iodine supply and prevention of iodine deficiency. The validity and comparability of iodine-related population studies can be improved by standardization, which was one of the goals of the EUthyroid project ...

Characteristic times in the standard map [PDF]

open access: yesPhysical Review E, 2019
We study and compare three characteristic times of the standard map, the Lyapunov time t_L, the Poincare recurrence time t_r and the stickiness (or escape) time t_{st}. The Lyapunov time is the inverse of the Lyapunov characteristic number LCN and in general is quite small.
