A New Approach on Helices in Pseudo-Riemannian Manifolds
Abstract and Applied Analysis, 2014 A proper curve α in the n-dimensional pseudo-Riemannian manifold (M,g) is called a Vn-slant helix if the function g(Vn,X) is a nonzero constant along α, where X is a parallel vector field along α and Vn is nth Frenet frame.

New type surfaces in terms of B-Smarandache Curves in Sol3
Acta Scientiarum: Technology, 2015 In this work, new type ruled surfaces in terms of B- Smarandache TM1 curves of biharmonic B- slant helices in the SOL3 are studied. We characterize the B- Smarandache TM1 curves in terms of their Bishop curvatures.

Curves According to the Successor Frame in Euclidean 3-Space
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2018 In thepresent study, the successor formulae of the successor curves defined byMenninger [1] are given. Then, by defining the successor planes, the geometricmeanings of the successor curvatures are investigated and the relations acrossthe components of ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

On characterizations of g n-helices with Euler angles
Open MathematicsCurvature and torsion, in their most general forms, are defined in terms of Euler angle-based parametrization via the Cartan matrix, which leads to the Serret-Frenet equations.

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Slant Helices and Darboux Helices in Myller Configuration
AxiomsIn this paper, we study slant helices (or ξ_2-helices) and Darboux helices in the Myller configuration M. We demonstrate that a curve in M is a slant helix if and only if it is a Darboux helix.

The proof of theorem which characterizes a slant helix
New Trends in Mathematical Science, 2016 Firstly, the axis of a slant helix is found. Secondly, the theorem which characterizes a slant helix is proved in detail. The importance of this theorem is stemed from that it has been led to doing many papers about slant helices.
