Numerical simulations were used to study the dynamics of a passive conservedscalar quantity entrained by a self-propelling viscous vortex ring. The trans-port and mixing process of the passive scalar variable were studied ...

"Wherever we turn, we see diverse things scaled for us, from cities to economies, from history to love. We know scale by many names and through many familiar antinomies: local and global, micro and macro events. Even the ...

Scattering and bound states for a spinless particle in the background of a kink-like smooth step potential, added with a scalar uniform background, are considered with a general mixing of vector and scalar Lorentz structures. ...

We quantize the low-energy sector of a massless scalar field in Reissner-Nordström spacetime. This allows the analysis of processes involving soft scalar particles occurring outside charged black holes. In particular, we ...

In this work, we implement a complex scalar dark matter (DM) candidate in a Ud(1)(B-L) gauge extension of the Standard Model. The model contains three right-handed neutrinos with different quantum numbers and a rich scalar ...

Introduction: Ornamental Angel fish (Pterophyllum scalare) is one of the main commercialized species from South America, with an important number of national and international dealers. Objective: To make a histological and ...
