COMET-LF: a compartmental model of dynamics of infection, disease, and elimination strategies for lymphatic filariasis [PDF]
BMC Infectious DiseasesBackground Lymphatic filariasis (LF) is a mosquito-borne disease caused by filarial worms. The WHO has targeted LF elimination by 2030. Mathematical models can help evaluate and guide elimination strategies. Methods We developed a new compartmental model—

On the Dynamics of Comets in Extrasolar Planetary Systems [PDF]
, 2019 Since very recently, we acquired knowledge on the existence of comets in extrasolar planetary systems. The formation of comets together with planets around host stars now seems evident.

Dynamical Constraints on the Origin of Main Belt Comets [PDF]
Meteoritics & Planetary Science, 2009 In an effort to understand the origin of the Main Belt Comets (MBCs) 7968 Elst-Pizzaro, 118401, and P/2005 U1, the dynamics of these three icy asteroids and a large number of hypothetical MBCs were studied.

Dynamical Simulation of the Interstellar Comet 3I/ATLAS
The Astrophysical Journal LettersComet 3I/ATLAS, also known as C/2025 N1, was discovered on 2025 July 1 UT by NASA Asteroid Terrestrial-impact Last Alert System (ATLAS), with a v _∞ ∼ 58 km s ^−1 . This is the fastest among the three interstellar objects discovered so far. In this work,

Status of the COMET experiment [PDF]
EPJ Web of Conferences, 2023 The COMET (COherent Muon to Electron Transition) experiment, currently being built in Tokai, Japan, will search for the coherent neutrinoless transition of muons to electrons in the coulomb field of atomic nuclei.

Recurring Activity Discovered on Quasi-Hilda 2009 DQ118
The Astrophysical Journal Letters, 2023 We have discovered two epochs of activity on quasi-Hilda 2009 DQ _118 . Small bodies that display comet-like activity, such as active asteroids and active quasi-Hildas, are important for understanding the distribution of water and other volatiles ...

Symposium - International Astronomical Union, 1992 The gravitational processes affecting the dynamics of comets are reviewed. At great distances from the Sun the motion of comets is primarily affected by the vertical component of the galactic field, as well as by encounters with stars and giant molecular clouds.

The Gateway from Centaurs to Jupiter-family Comets: Thermal and Dynamical Evolution
The Astrophysical Journal, 2023 It was recently proposed that there exists a “gateway” in the orbital parameter space through which Centaurs transition to Jupiter-family comets (JFCs).
