Ferroelectric nematic liquids with conics [PDF]
Nature Communications, 2023 Defect lines shaped as conic sections are common in smectic liquid crystals, where they manifest equidistance of molecular layers curled in space. Here authors present hyperbolas and parabolas as domain walls in ferroelectric nematics, which are shaped ...

Mirror-centered representation of a focusing hyperbolic mirror for X-ray beamlines [PDF]
Journal of Synchrotron RadiationConic sections are commonly used in reflective X-ray optics. Hyperbolic mirrors can focus a converging light source and are frequently paired with elliptical or parabolic mirrors in Wolter type configurations.

Approximation of conic sections by weighted Lupaş post-quantum Bézier curves
Demonstratio Mathematica, 2022 This paper deals with weighted Lupaş post-quantum Bernstein blending functions and Bézier curves constructed with the help of bases via (p,q)\left(p,q)-integers. These blending functions form normalized totally positive bases.

On the Symbolic 2-Plithogenic Real Analysis by Using Algebraic Functions [PDF]
Neutrosophic Sets and Systems, 2023 In this paper, we study the symbolic 2-plithogenic real functions with one variable by using a special algebraic function called AH-isometry. In addition, we discuss the symbolic 2-plithogenic simple differential equations and conic sections by using ...
