Least energy nodal solutions for elliptic equations with indefinite nonlinearity [PDF]
Electronic Journal of Qualitative Theory of Differential Equations, 2014 We prove the existence of a nodal solution with two nodal domains for the Dirichlet problem with indefinite nonlinearity \begin{equation*} -\Delta_p u = \lambda |u|^{p-2} u + f(x) |u|^{\gamma-2} u \end{equation*} in a bounded domain $\Omega \subset ...

A reactive algorithm for deducing nodal forwarding behavior in a multihop ad-hoc wireless network in the presence of errors [PDF]
International Journal of Electronics and Telecommunications, 2020 A novel algorithm is presented to deduce individual nodal forwarding behavior from standard end-to-end acknowledgments. The algorithm is based on a well-established mathematical method and is robust to network related errors and nodal behavior changes ...

Rate-dependency of action potential duration and refractoriness in isolated myocytes from the rabbit AV node and atrium [PDF]
, 2000 During atrial fibrillation, ventricular rate is determined by atrioventricular nodal (AVN) conduction, which in part is dependent upon the refractoriness of single AVN cells.
