Effect of additively manufactured core geometry on the transverse compression performance of foam‐filled sandwich composite structures

open access: yesPolymer Composites, EarlyView.
Effect of additively manufactured core on the transverse compression performance of foam‐filled sandwich composite structures. Abstract This paper presents a comprehensive assessment of the quasi‐static compression response of novel 3D‐printed carbon fiber‐reinforced polymer (CFRP) and glass fiber‐reinforced polymer (GFRP) core‐based corrugated foam ...

Cold ions of ionospheric origin observed at the dayside magnetopause and their effects on magnetic reconnection [PDF]

open access: yes, 2015
Thesis (Ph.D.) University of Alaska Fairbanks, 2015Magnetic reconnection at the dayside magnetopause is one of the most important mechanisms that efficiently transfers solar wind particles, momentum, and energy into the magnetosphere.

The European honey buzzard (Pernis apivorus) as an ally for the control of the invasive yellow‐legged hornet (Vespa velutina nigrithorax)

open access: yesPest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.
The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.

Deep Reinforcement Learning‐Based Control for Real‐Time Hybrid Simulation of Civil Structures

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Real‐time Hybrid Simulation (RTHS) is a cyber‐physical technique that studies the dynamic behavior of a system by combining physical and numerical components that are coupled through a boundary condition enforcer. In structural engineering, the numerical components are subjected to environmental loads that become dynamic displacements of the ...

Functionalized Multi‐Walled Carbon Nanotube Enhanced Myogenic Differentiation for Aligned Topography‐Induced Skeletal Muscle Engineering

open access: yesSmall, EarlyView.
Conductive interfaces are known to support muscle engineering approaches, but without proper guidance, the muscle will not be functional if not properly aligned. Therefore, combining carbon nanotubes and aligned topography enhances muscle tissue engineering approaches, displaying a synergetic effect.
