Isophote curves on spacelike surfaces in Lorentz-Minkowski space E31 [PDF]

open access: greenarXiv, 2012
Isophote curve consists of a locus of surface points whose normal vectors make a constant angle with a fixed vector (the axis). In this paper, we define an isophote curve on a spacelike surface in Lorentz-Minkowski space and then find its axis as timelike and spacelike vectors via the Darboux frame.

On Caputo fractional Bertrand Curves in E3 and E31

open access: bronzeFilomat
In this article, we examine Bertrand curves in E3 and E31 by using the Caputo fractional derivative which we call ?-Bertrand Curves. First, we consider ?-Bertrand curves in E3 and we give a characterization of them. Then, we study ?-Bertrand curves in E31 and we prove the necessary and sufficient condition for a ?-Bertrand curves in E31 by ...

Slant helices in Minkowski 3-space E31 with Sasai’s modified frame fields

open access: goldFilomat, 2022
In this paper, we study slant helix using modified orthogonal frame in Minkowski space E31 with timelike, lightlike and spacelike axes. We also study a general slant helix with the Killing vector field axis.

Subtle pH differences trigger single residue motions for moderating conformations of calmodulin [PDF]

open access: yesarXiv, 2011
This study reveals the essence of ligand recognition mechanisms by which calmodulin (CaM) controls a variety of Ca2+ signaling processes. We study eight forms of calcium-loaded CaM each with distinct conformational states. Reducing the structure to two degrees of freedom conveniently describes main features of conformational changes of CaM via ...

Isophote curves on timelike surfaces in Minkowski 3-space [PDF]

open access: yes, 2012
Isophote comprises a locus of the surface points whose normal vectors make a constant angle with a fixed vector. In this paper, isophote curves are studied on timelike surfaces in Minkowski 3-space E31. The axises of spacelike and timelike isophote curves are found via their Darboux frames.

E7-47, E7-54, E29-56, and E31-10 Apple Germplasm with Multiple Pest Resistance [PDF]

open access: hybridHortscience, 1989
E7-47, E7-54, E29-56, and E31-10 apples (Malus × domestica Borkh) were found resistant to apple scab, [Venturia inaequalis (Cke.) Wint.] in greenhouse tests and in the field.
