Piecewise expanding maps: combinatorics, dynamics and representation of rational numbers

ESAIM: Proceedings and Surveys, 2014
We establish combinatorial properties of the dynamics of piecewise increasing, continuous, expanding maps of the interval such as description of periodic and pre-periodic points, primitiveness of truncated itineraries and length of ...

Multidimensional Josephson vortices in spin-orbit coupled Bose-Einstein condensates: snake instability and decay through vortex dipoles

, 2016
We analyze the dynamics of Josephson vortex states in two-component Bose-Einstein condensates with Rashba-Dresselhaus spin-orbit coupling by using the Gross-Pitaevskii equation.

Resonant Orbital Dynamics of CBERS Satellites [PDF]

Proceeding Series of the Brazilian Society of Computational and Applied Mathematics, 2016
Synchronous satellites have been studied in literature, due to the research of resonant orbits. In this work, CBERS - 2 (China-Brazil Earth Resource Satellite) satellite is investigated observing resonance effects which compose your orbit. Energy’s curves are observed indicating the presence of Kozai’s resonance in your orbit.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Unraveling the dynamics of magnetization in topological insulator-ferromagnet heterostructures via spin-orbit torque

npj Spintronics
Spin–orbit coupling is a relativistic effect coupling the orbital angular momentum with the spin, which determines the physical properties of condensed matter.

Orbital dynamics of the solar basin

Journal of High Energy Physics
Abstract We study the dynamics of the solar basin — the accumulated population of weakly-interacting particles on bound orbits in the Solar System. We focus on particles starting off on Sun-crossing orbits, corresponding to initial conditions of production inside the Sun, and investigate their evolution over the age of the Solar ...

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

FEBS Letters, EarlyView.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

A generalized super-twisting algorithm-based adaptive fixed-time controller for spacecraft pose tracking

Open Astronomy
A generalized super-twisting second-order sliding mode adaptive fixed-time control law, which is used for spacecraft pose tracking in the presence of internal and external uncertainties, is proposed.

Drift-diffusion model for spin-polarized transport in a non-degenerate 2DEG controlled by a spin-orbit interaction

, 2004
We apply the Wigner function formalism to derive drift-diffusion transport equations for spin-polarized electrons in a III-V semiconductor single quantum well. Electron spin dynamics is controlled by the linear in momentum spin-orbit interaction.

Space dependent, full orbit effects on runaway electron dynamics in tokamak plasmas

, 2017
The dynamics of RE (runaway electrons) in fusion plasmas span a wide range of temporal scales, from the fast gyro-motion, ∼ 10 − 11 s, to the observational time scales, ∼ 10 − 2 → 1 s. To cope with this scale separation, RE are usually studied within the
