Invariant manifolds, discrete mechanics, and trajectory design for a mission to Titan [PDF]
, 2009 With an environment comparable to that of primordial Earth, a surface strewn with liquid hydrocarbon lakes, and an atmosphere denser than that of any other moon in the solar system, Saturn's largest moon Titan is a treasure trove of potential scientific ...

, 1998 Numerical integrations in celestial mechanics often involve the repeated computation of a rotation with a constant angle. A direct evaluation of these rotations yields a linear drift of the distance to the origin.

Foraging by predatory ants: A review
Insect Science, EarlyView.This review focuses on ecological and behavioral characteristics of foraging in ants showing the wide diversity of cases. Most ants can feed on sugary substances, but some ground‐nesting species are strict predators. Except army ants during the nomadic phase, they are central‐place foragers that can recruit nestmates when necessary. They prey mostly on

Avoiding collisions under topological constraints in variational problems coming from celestial mechanics [PDF]
arXiv, 2014 In a singular potential setting, we generalize a method which allows to show that minimizers under topological constraints of the action functional (or of the Maupertuis') are collision-free. This methods applies to $3$-dimensional problems of celestial mechanics exhibiting a particular cylindrical symmetry, as well as to planar problems of $N$-centre ...

Canonical elements for collision orbits [PDF]
, 2000 I derive a set of canonical elements that are useful for collision orbits (perihelion distance approaching zero at fixed semimajor axis). The coordinates are the mean anomaly and the two spherical polar angles at aphelion.

Imaging malaria parasites across scales and time
Journal of Microscopy, EarlyView.Abstract The idea that disease is caused at the cellular level is so fundamental to us that we might forget the critical role microscopy played in generating and developing this insight. Visually identifying diseased or infected cells lays the foundation for any effort to curb human pathology.

Applications to celestial mechanics
, 2022 Recently an asymptotic formula for the distance of the invariant manifolds of L3 in the RCP3BP when the mass parameter tends to zero was proven. In this study we numerically check the formula using high precision routines and give approximate values for the constants involved.

Journal of Economic Surveys, EarlyView.Abstract The current review systematically synthesizes existing literature to provide a comprehensive overview of the nature of financial crimes in Africa and their impact on economic growth. We adopted the PRISMA protocol to identify 128 papers from the Scopus database, which were analyzed using MS Excel, VOSviewer, and R‐packages (Bibliometrix).
