Displaced solar sail orbits : dynamics and applications [PDF]
, 2010 We consider displaced periodic orbits at linear order in the circular restricted Earth-Moon system, where the third massless body is a solar sail. These highly non-Keplerian orbits are achieved using an extremely small sail acceleration.

Probing the local dynamics of periodic orbits by the generalized alignment index (GALI) method
, 2011 As originally formulated, the Generalized Alignment Index (GALI) method of chaos detection has so far been applied to distinguish quasiperiodic from chaotic motion in conservative nonlinear dynamical systems.

Estimation of the number of periodic orbits [PDF]
Pacific Journal of Mathematics, 1996 The author is concerned with estimating the asymptotic growth rate of the Nielsen numbers \(N(f^n)\) for a map \(f : X \to X\) of a compact connected polyhedron. Pick a point \(v \in X\) and a path \(w\) from \(v\) to \(f(v)\). Denote \(G : = \pi_1 (X,w)\) and let \(f_G : = w_* f_* : G \to G\).

Periodic orbits in the logarithmic potential [PDF]
Astronomy & Astrophysics, 2008 Analytic methods to investigate periodic orbits in galactic potentials. To evaluate the quality of the approximation of periodic orbits in the logarithmic potential constructed using perturbation theory based on Hamiltonian normal forms. The solutions of the equations of motion corresponding to periodic orbits are obtained as series expansions computed

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.

Vacuolar transport and function of Saccharomyces cerevisiae sterol ester hydrolase Tgl1
FEBS Letters, EarlyView.Tgl1, one of yeast sterol ester hydrolases, had been found on the lipid droplets where sterol esters are mainly stored. This study revealed that Tgl1 is transported into the vacuole depending on the ESCRT‐I–III complex, and that it exhibits intra‐vacuolar sterol ester hydrolase activity.

The role of fibroblast growth factors in cell and cancer metabolism
FEBS Letters, EarlyView.Fibroblast growth factor (FGF) signaling regulates crucial signaling cascades that promote cell proliferation, survival, and metabolism. Therefore, FGFs and their receptors are often dysregulated in human diseases, including cancer, to sustain proliferation and rewire metabolism.

A Note on Almost Periodic Points and Minimal Sets in T1- and T2-Spaces
Discrete Dynamics in Nature and Society, 2008 We show that (1) there exist almost periodic orbits in T2-spaces of which the closures are not minimal sets; (2) there exist minimal sets in locally compact T1-spaces which are not compact; (3) there exist almost periodic orbits in T2-spaces of which the

Instabilities and stickiness in a 3D rotating galactic potential
, 2013 We study the dynamics in the neighborhood of simple and double unstable periodic orbits in a rotating 3D autonomous Hamiltonian system of galactic type. In order to visualize the four dimensional spaces of section we use the method of color and rotation.
