Analytic and numeric analysis for deformation of non-prismatic beams resting on elastic foundations
Beni-Suef University Journal of Basic and Applied Sciences, 2021 Background The buckling load as well as the natural frequency under axial load for non-prismatic beam is a changeling problem. Determination of buckling load, natural frequency, and elastic deflection is very important in civil applications.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix
Advanced Materials, EarlyView.3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Per Linguam : A Journal of Language Learning, 2022 It is expected that English Home Language (Eng HL), as a subject, is more complex than English First Additional Language (Eng FAL). This article aims to uncover the reality of this expectation by comparatively investigating the linguistic complexity of ...
