Coalition formation problems with externalities
(2023)We study coalition formation problems with externalities. We prove that, if expectations are not prudent a stable coalitions structure may fail to exist. Under prudent expectations a stable and efficient coalition structure ...

A description of the epidemiological dynamics of Chagas disease via mathematical modeling
; ; Cancino-Faure, Beatriz
; ; (2023)
Chagas disease is caused by the protozoan Trypanosoma cruzi, which parasitizes many mammals, including humans. Its vectors are blood-feeding hematophagous triatomine insects of different species, which vary according to ...

Early regulation of corticosteroid receptor expression in rainbow trout (Oncorhynchus mykiss) gills is mediated by membrane-initiated cortisol signaling
(2023)Cortisol is a key stress-related hormone involved in the physiological adjustments of fish. In gills, cortisol contributes to acclimatization to changes in environmental salinity, promoting both ion uptake or salt excretion. ...

A model for incompressible fluids using finite element methods for the Brinkman problem
(2020)The partial differential equations for fluid flow dynamics based on the Brinkman equations, written in terms of velocity-vorticity and pressure in three dimensions, are essential for predicting climate, ocean currents, ...

The role of upwelling intermittence in the development of hypoxia and nitrogen loss over the Oregon shelf
(2020)Coastal upwelling regions represent less than 2% of the marine biosphere's volume. Nonetheless, local biogeochemical processes have a considerable impact on the structure and functioning of the global oceans. In this study ...

Northern and central Chile still free of emerging flaviviruses in mosquitoes (Diptera: Culicidae)
Cancino-Faure, Beatriz; ; ; ; ; ; ; ; (2023)
Geographic isolation and strict control limits in border areas have kept Chile free from various pathogens, including Flavivirus. However, the scenario is changing mainly due to climate change, the reintroduction of more ...

Global bifurcation results for nonlinear dynamic equations on time scales
(2020)We prove a global bifurcation result for a parameterized dynamic equation on time scales. The approach is topological and based on a notion of topological degree for compact perturbations on nonlinear Fredholm maps in ...
