A balance equation determines a switch in neuronal excitability. [PDF]

open access: yesPLoS Computational Biology, 2013
We use the qualitative insight of a planar neuronal phase portrait to detect an excitability switch in arbitrary conductance-based models from a simple mathematical condition. The condition expresses a balance between ion channels that provide a negative

A ROBUST SECOND-ORDER MULTIPLE BALANCE METHOD FOR TIME-DEPENDENT NEUTRON TRANSPORT SIMULATIONS [PDF]

open access: yesEPJ Web of Conferences, 2021
A second-order “Time-Dependent Multiple Balance” (TDMB) method for solving neutron transport problems is introduced and investigated. TDMB consists of solving two coupled equations: (i) the original balance equation (the transport equation integrated ...

The half-order energy balance equation – Part 2: The inhomogeneous HEBE and 2D energy balance models [PDF]

open access: yesEarth System Dynamics, 2021
In Part 1, I considered the zero-dimensional heat equation, showing quite generally that conductive–radiative surface boundary conditions lead to half-ordered derivative relationships between surface heat fluxes and temperatures: the half-ordered energy ...
