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 ...

A special perturbation method in orbital dynamics [PDF]
Celestial Mechanics and Dynamical Astronomy, 2006 Bead models are used in dynamical simulation of tethers. These models discretize a cable using beads distributed along its length. The time evolution is obtained nu- merically. Typically the number of particles ranges between 5 and 50, depending on the required accuracy. Sometimes the simulation is extended over long periods (several years).

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Orbit design for future SpaceChip swarm missions [PDF]
, 2010 The effect of solar radiation pressure and atmospheric drag on the orbital dynamics of satellites-on-a-chip (SpaceChips) is exploited to design long-lived orbits about the Earth.

A consistent numerical integration of orbit, tides, and rotation for synchronous satellites
Astronomy & AstrophysicsContext. Consistently modelling the effects of the tides raised on a satellite on the dynamics of the satellite itself and on those of a nearby spacecraft (either in orbit or performing a flyby) requires accounting for the instantaneous tidal deformation

Time-resolved 3D imaging of ultrafast spin–orbit wave packet dynamics
New Journal of Physics, 2019 We combine bichromatic polarization pulse shaping with photoelectron imaging tomography for time-resolved spatial imaging of ultrafast spin–orbit wave packet (SOWP) dynamics in atoms.

Curvature in orbital dynamics [PDF]
American Journal of Physics, 2005 The physical basis and the geometrical significance of the equation for the orbit of a particle moving under the action of external forces is exhibited by deriving this equation in a coordinate-independent representation in terms of the radius of curvature of the orbit.

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.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
