On the Assocıated Curves of a Frenet Curve in R_1^4
Cumhuriyet Science Journal, 2022 In the present work, we have dealt with the properties of associated curves of a Frenet curve in R14. In addition to this, we define principal direction curve, B_1 -direction curve, B_2- direction curve of a given Frenet curve by using integral curves ...

Conjugate mates for non-null Frenet curves
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019 For each non-null Frenet curve \gamma in Minkowski 3-space, there exists a unique unit speed non-null curve tangentto the principal binormal vector field of \gamma. We briefly call this curve the conjugate mate of\gamma . The aim of thispaper is to prove

CHARACTERIZATION OF THE SLANT HELIX AS SUCCESSOR CURVE OF THE GENERAL HELIX
International Electronic Journal of Geometry, 2014 In classical curve theory, the geometry of a curve in three dimen- sions is essentially characterized by their invariants, curvature and torsion. When they are given, the problem of nding a corresponding curve is known as 'solving natural equations'. Explicit solutions are known only for a handful of curve classes, including notably the plane curves ...

The auto-inhibitory role of the EPAC hinge helix as mapped by NMR. [PDF]
PLoS ONE, 2012 The cyclic-AMP binding domain (CBD) is the central regulatory unit of exchange proteins activated by cAMP (EPAC). The CBD maintains EPAC in a state of auto-inhibition in the absence of the allosteric effector, cAMP.

General helices that lie on the sphere $S^{2n}$ in Euclidean space $E^{2n+1}$
Universal Journal of Mathematics and Applications, 2018 In this work, we give two methods to generate general helices that lie on the sphere $S^{2n}$ in Euclidean (2n+1)-space $E^{2n+1}$.

Structural basis of antifreeze activity of a bacterial multi-domain antifreeze protein. [PDF]
PLoS ONE, 2017 Antifreeze proteins (AFPs) enhance the survival of organisms inhabiting cold environments by affecting the formation and/or structure of ice. We report the crystal structure of the first multi-domain AFP that has been characterized.

Some new types of associated curves in Euclidean 3-space
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018 In this paper, we introduce the concept of D-direction curve and C- direction curve of a given curve using the alternative frame –N,C,W} in Euclidean 3-space.

Double stranded antiferromagnetic helix as an efficient spin filter
Results in Physics, 2023 We report a large degree of spin filtration in a double stranded (ds) antiferromagnetic helix (AFH) system. Generally spin channel separation is not possible when a magnetic system possesses a vanishing net magnetization.
