Where the linearized Poisson-Boltzmann cell model fails: the planar case as a prototype study.

TL;DR: The linearized Poisson-Boltzmann (PB) approximation is investigated for the classical problem of two infinite, uniformly charged planes in electrochemical equilibrium with an infinite monovalent salt reservoir and asymptotic expressions for the semi-grand-canonical potential and the osmotic-pressure difference are provided.

Electrostatic and mechanical properties of a flat lipid bilayer containing ionic lipids: Possibility for formation of domains with different surface charges

TL;DR: In this article, the electrostatic and the mechanical properties of a flat lipid bilayer, containing ionic lipid, were studied theoretically, and the degree of dissociation and free energy of the system due to electrostatic interactions were obtained as a function of the relative concentration of the ions in the membrane.

Progress toward controlling in vivo fibrillating sheep atria using a nonlinear-dynamics-based closed-loop feedback method.

TL;DR: Preliminary experiments on controlling in vivo atrial fibrillation using a closed-loop feedback protocol that measures the dynamics of the right atrium at asingle spatial location and applies control perturbations at a single spatial location are described.

Insect Photopigments: Photoreceptor Spectral Sensitivities and Visual Adaptations

TL;DR: Although the main focus is on the properties of visual pigments, considerable attention is also given to other photostable filter pigments that importantly modify the spectral properties of the photoreceptors.
Journal ArticleDOI

The evolution of mammalian cortex, from lamination to arealization.

TL;DR: The simulation of neural network models demonstrates that a nonlaminated patch of cortex must compromise between transmitting "where" information, explicitly mapped, topographically, on the cortical sheet, and retrieving "what", represented by the distributed firing pattern across neurons.
