Differential Diffusivity of Nodal and Lefty Underlies a Reaction-Diffusion Patterning System [PDF]
Science, 2012 Reaction-Diffusion Patterning Six decades ago, Alan Turing proposed the reaction-diffusion model to explain how complex patterns emerge during morphogenesis. In this model, an activator activates both itself and an inhibitor (the “reaction”), with the activator being less mobile than the inhibitor (“diffusion ...

Reconstruction of the Diffusion Operator from Nodal Data
Zeitschrift für Naturforschung A, 2010 In this paper, we deal with the inverse problem of reconstructing the diffusion equation on a finite interval. We prove that a dense subset of nodal points uniquely determine the boundary conditions and the coefficients of the diffusion equation. We also provide constructive procedure for them.

COMPARISONS AMONG THREE COUPLING FORMS OF CYLINDRICAL NODAL EXPANSION METHODS [PDF]
EPJ Web of Conferences, 2021 Nodal expansion method (NEM) is a typical nodal method in solving neutron diffusion equation in coarse mesh spatial discretization. NEM has been extended to cylindrical geometry in previous studies.

GENERATION OF NODAL CORE SIMULATOR UTILIZING VERA [PDF]
EPJ Web of Conferences, 2021 Nuclear core simulators based upon few-group nodal diffusion method currently are widely used to predict light water reactor core behavior. Nodal parameters’ input, e.g. cross-sections, discontinuity factors, and pin form factors, are typically generated

Nodal geometry, heat diffusion and Brownian motion [PDF]
Analysis & PDE, 2018 We use tools from $n$-dimensional Brownian motion in conjunction with the Feynman-Kac formulation of heat diffusion to study nodal geometry on a compact Riemannian manifold $M$. On one hand we extend a theorem of Lieb and prove that any nodal domain $ _ $ almost fully contains a ball of radius $\sim \frac{1}{\sqrt }$.

Variant of Green's Function Nodal Method for Neutron Diffusion [PDF]
Journal of Nuclear Science and Technology, 1990 A variant of the Green's function nodal method derived from the boundary integral form of the multigroup neutron diffusion equation in rectangular geometry is presented. As usual in the nodal methods, the multi-dimensional diffusion equation is integrated in the transverse direction.
