Advanced Engineering Materials, EarlyView.Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Advanced Engineering Materials, EarlyView.Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Electronic Journal of Differential Equations, 2011 Using Mawhin's continuation theorem of coincidence degree theory, we establish the existence of $2^{n+m}$ positive periodic solutions for a non-autonomous Lotka-Volterra network-like predator-prey system with harvesting terms. Here n and m denote the

Polarization symmetry as a signature of Bell states in Compton scattering
Physical Review ResearchWe analyze bipartite photon states in coincidence Compton polarimetry at energies where polarization must be inferred from Compton scattering. Polarization symmetry, defined as equality of signal and idler degree-of-polarization responses for all ...

Advanced Engineering Materials, EarlyView.Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Coincidence Degree and Fixed Point Theory Applied to the Study of Solutions of a Nonlinear Fractional Boundary Value Problem [PDF]
This work is devoted to the study of a class of fractional boundary value problems using the (left) Caputo derivative and with the particularity of being resonant, i.e., the associated homogeneous problem admits a nontrivial solution.

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion
Advanced Engineering Materials, EarlyView.Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐

Electron emission in H sup 0 --atom collisions: A coincidence study of the angular dependence [PDF]
, 1990 Differential electron emission occurring as the result of fast hydrogen atom impact on helium and argon targets has been studied using standard non-coincidence and emitted electron-ionized projectile coincidence techniques. Impact energies were 0.5 and 1
