Electrical Pacing of Cardiac Tissue Including Potassium Inward Rectification. [PDF]

open access: yesPLoS ONE, 2015
In this study cardiac tissue is stimulated electrically through a small unipolar electrode. Numerical simulations predict that around an electrode are adjacent regions of depolarization and hyperpolarization.

Characterization of Spherical and Plane Curves Using Rotation Minimizing Frames [PDF]

open access: yes, 2019
In this work, we study plane and spherical curves in Euclidean and Lorentz-Minkowski 3-spaces by employing rotation minimizing (RM) frames. By conveniently writing the curvature and torsion for a curve on a sphere, we show how to find the angle between ...

On the Geometrical Properties of the Lightlike Rectifying Curves and the Centrodes

open access: yesMathematics, 2021
This paper mainly focuses on some notions of the lightlike rectifying curves and the centrodes in Minkowski 3-space. Some geometrical characteristics of the three types of lightlike curves are obtained.

Generic Properties of Framed Rectifying Curves [PDF]

open access: yesMathematics, 2019
The position vectors of regular rectifying curves always lie in their rectifying planes. These curves were well investigated by B.Y.Chen. In this paper, the concept of framed rectifying curves is introduced, which may have singular points. We investigate the properties of framed rectifying curves and give a method for constructing framed rectifying ...

Wine polyphenol resveratrol inhibits contractions of isolated rat uterus by activation of smooth muscle inwardly rectifying potassium channels [PDF]

open access: yesVeterinarski Glasnik, 2016
Resveratrol is a phytoalexin produced in a number of plant species including grapes. The benefit of resveratrol to health is widely reported. Resveratrol has been found to promote relaxation of non-pregnant and pregnant uterus, but its mechanism

Heterogeneous Extractive Batch Distillation of Chloroform - Methanol – Water : Feasibility and Experiments [PDF]

open access: yes, 2008
A novel heterogeneous extractive distillation process is considered for separating the azeotropic mixture chloroform – methanol in a batch rectifying column, including for the first time an experimental validation of the process.

Inkjet printed metal insulator semiconductor (MIS) diodes for organic and flexible electronic application [PDF]

open access: yes, 2017
All inkjet printed rectifying diodes based on a metal-insulator-semiconductor (MIS) layer stack are presented. The rectifying properties were optimized by careful selection of the insulator interlayer thickness and the layout structure.

Nonlinear dynamics, rectification, and phase locking for particles on symmetrical two-dimensional periodic substrates with dc and circular ac drives [PDF]

open access: yes, 2003
We investigate the dynamical motion of particles on a two-dimensional symmetric periodic substrate in the presence of both a dc drive along a symmetry direction of the periodic substrate and an additional circular ac drive.
