Experimental Characterization of Mycelium‐Based Composites Under Multiple Loading Conditions
Advanced Engineering Materials, EarlyView.This study examines the mechanical response of mycelium‐based composites under compression, shear, and tension using mechanical testing and imaging methods. The comparison between unpressed and hot‐pressed specimens shows that hot pressing is associated with higher compression and shear stiffnesses.

Principal eigenvalues and the Dirichlet problem for fully nonlinear operators [PDF]
, 2008 Advances in Mathematics, 218(1) (2008), 105-135.International audienceWe prove the existence of two principal eigenvalues and eigenfunctions for 1-homogeneous convex uniformly elliptic fully nonlinear operators, study their properties, and discuss ...

Curvelets, Wave Atoms, and Wave Equations [PDF]
, 2006 We argue that two specific wave packet families---curvelets and wave atoms---provide powerful tools for representing linear systems of hyperbolic differential equations with smooth, time-independent coefficients.

Advanced Engineering Materials, EarlyView.This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Pseudoconvex fully nonlinear partial differential operators: strong comparison theorems [PDF]
, 2004 We introduce a new class of curvature PDOs describing relevant properties of real hypersurfaces of Cn+1. In our setting, the pseudoconvexity and the Levi form play the same role as the convexity and the real Hessian matrix play in the real Euclidean one.

A Practical Noise2Noise Denoising Pipeline for High‐Throughput Raman Spectroscopy
Advanced Engineering Materials, EarlyView.A lightweight and reproducible denoising pipeline for high‐throughput Raman spectroscopy is introduced, based on a 1D convolutional autoencoder trained with a Noise2Noise strategy. Using only repeated short‐exposure acquisitions, the method suppresses stochastic noise without reference spectra, enabling reliable spectral reconstruction while preserving

G-Metric Spaces via Fixed Point Techniques for Ψ-Contraction with Applications
Fractal and FractionalThe primary aim of this manuscript is to establish unique fixed point results for a class of Ψ-contraction operators in complete G-metric spaces. By combining and extending various fixed point theorems in the context of Ψ-contraction operators, we ...

Hybrid Metal–Carbon Ink for Printed Stretchable Temperature Sensors
Advanced Engineering Materials, EarlyView.We prepare conductive inks for temperature sensing with silver flakes and carbon or graphite flakes in a silicone elastomer matrix. Silver dominates the temperature‐dependent conductivity, while the carbon filler network ensures the stability of the conductive pathways and retains function under strain.
