On rectifying ruled surfaces [PDF]

open access: yesKuwait Journal of Science, 2020
In this study, we define general rectifying ruled surfaces in the Euclidean 3-space E^3. We give some characterizations of rectifying ruled surfaces by considering the curvatures of base curve.

Rectifiable Curves in Proximally Smooth Sets [PDF]

open access: yesSet-Valued and Variational Analysis, 2021
We provide an algorithm of constructing a rectifiable curve between two sufficiently close points of a proximally smooth set in a uniformly convex and uniformly smooth Banach space. Our algorithm returns a reasonably short curve between two sufficiently close points of a proximally smooth set, is iterative and uses a certain modification of the metric ...

Alignment and rectifying properties of donor-electron bridge-acceptor molecules [PDF]

open access: yes, 2007
Molecular electronics based on the bottom-up approach appears to be a promising alternative to overcome the limitations of the top-down lithographic fabrication of electronic devices.

Intersection of Continua and Rectifiable Curves [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 2013
AbstractWe prove that for any non-degenerate continuum K ⊆ ℝd there exists a rectifiable curve such that its intersection with K has Hausdorff dimension 1. This answers a question of Kirchheim.

Some characterizations of timelike rectifying curves in de sitter 3 space

open access: yesCumhuriyet Science Journal, 2020
De Sitter space is a non-flat Lorentzian space form with positive constant curvature which plays an important role in the theory of relativity. In this paper, we define the notions of timelike rectifying curve and timelike conical surface in De Sitter 3 ...

Cardiac strength-interval curves calculated using a bidomain tissue with a parsimonious ionic current. [PDF]

open access: yesPLoS ONE, 2017
The strength-interval curve plays a major role in understanding how cardiac tissue responds to an electrical stimulus. This complex behavior has been studied previously using the bidomain formulation incorporating the Beeler-Reuter and Luo-Rudy dynamic ...

Monodromy and K-theory of Schubert curves via generalized jeu de taquin [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
We establish a combinatorial connection between the real geometry and the K-theory of complex Schubert curves Spλ‚q, which are one-dimensional Schubert problems defined with respect to flags osculating the rational normal curve.

Finslerian Viewpoint to the Rectifying, Normal, and Osculating Curves

open access: yesInternational Electronic Journal of Geometry, 2022
The theory of Finsler metric was introduced by Paul Finsler, in 1918. The author defines this metric using the Minkowski norm instead of the inner product. Therefore, this geometry is a more general metric and includes the Riemannian metric. In the present work, using the Finsler metric, we investigate the position vector of the rectifying, normal and ...

Direction Curves Associated with Darboux Vectors Fields and Their Characterizations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2021
In this paper, we consider the Darboux frame of a curve α lying on an arbitrary regular surface and we use its unit osculator Darboux vector D¯o, unit rectifying Darboux vector D¯r, and unit normal Darboux vector D¯n to define some direction curves such ...

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.
