Ranging behavior of female and male Shiny Cowbirds and Screaming Cowbirds while searching for host nests [PDF]

open access: yes, 2014
Pusimos a prueba la hipótesis que los tordos parásitos de cría buscan y localizan nidos de hospedadores dentro de un área relativamente constante, ya que esto facilitaría el monitoreo de nidos a través del tiempo y la sincronización del parasitismo con ...

Effects of Audible Human Disturbances on Koala (Phascolarctos Cinereus) Behavior in Queensland, Australia and Implications for Management [PDF]

open access: yes, 2015
Koala populations are declining, and a contributing factor is stress, which can lead to greater susceptibility to disease. Koalas need about twenty hours of rest daily to remain healthy and unstressed.

Targeting p38α in cancer: challenges, opportunities, and emerging strategies

open access: yesMolecular Oncology, EarlyView.
p38α normally regulates cellular stress responses and homeostasis and suppresses malignant transformation. In cancer, however, p38α is co‐opted to drive context‐dependent proliferation and dissemination. p38α also supports key functions in cells of the tumor microenvironment, including fibroblasts, myeloid cells, and T lymphocytes.

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

open access: yesInternational Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.
