A quasilinear Keller-Segel model with saturated discontinuous advection

Maria Pia Gualdani · Mikel Ispizua · Nicola Zamponi

We consider the singular limit of a chemotaxis model of bacterial collective motion recently introduced in arXiv:2009.11048 [math.AP]. The equation models aggregation-diffusion phenomena with advection that is discontinuous and depends sharply on the gradient of the density itself. The quasi-linearity of the problem po...

Cues in the mist: intersexual patterns of scent-marking behavior in the Andean bear ( Tremarctos ornatus ) and temporal relationships with free-ranging dogs’ activity in cloud forests of southern Huila, Colombia

Valentina López-Velasco · Juan C. Cepeda-Duque · Carlos A. Agudelo Henao · Jorge A. Astwood-Romero · y 3 más

Communication through scent-marking plays a crucial role in animal fitness, particularly for solitary species such as the Andean bear, in which it fulfills the function of advertising individual attributes to conspecifics and managing social interactions. However, research on the scent-marking behavior of Andean bears...

The image of scalar hairy black holes with asymmetric potential

Carlos A. Benavides-Gallego · Eduard Alexis Larrañaga

Abstract Black hole accretion disks are a fascinating topic in astrophysics, as they play a crucial role in several high-energy situations. This paper investigates the optical appearance of scalar hairy black holes (SHBHs) with asymmetric potential, a numerical solution obtained in Phys. Rev. D 68, 044006 (2003). Since...
