Slant helices in Minkowski 3-space E31 with Sasai’s modified frame fields
Filomat, 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. Furthermore, we give a non-trivial example and find the relations for curvature and torsion of f-biharmonic slant helix.

Forecasting Euro Area Inflation Using Single-Equation and Multivariate VAR–Models
Folia Oeconomica Stetinensia, 2017 Forecasting inflation is of key relevance for central banks, not least because the objective of low and stable inflation is embodied in most central banks’ mandates and the monetary policy transmission mechanism is well known to be subject to long and ...

On Caputo fractional Bertrand Curves in E3 and E31
FilomatIn 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 ...

Advanced Science, EarlyView.Interlayer sliding in the RuO2Zn2F2 bilayer induces ferroelectricity and enables reversible valley polarization switching. The electric dipole and valley‐resolved band edges are intimately coupled, revealing sliding ferroelectricity as a powerful mechanism for electrical control of valley degrees of freedom in 2D materials.
