Synergistic effects of annealing heat treatment and lignocellulose fiber incorporation on the thermal, mechanical, and water absorption properties of poly(lactic acid)‐based biocomposites

Polymer Composites, EarlyView.
The effect of molecular structure on the moisture absorption of PLA/cellulose biocomposites. Abstract This study investigates the effect of annealing heat treatment on polymer composites composed entirely of biodegradable components. Poly(lactic acid) (PLA) was used as the matrix material paired with three different types of commercial lignocellulose ...

Long‐Term Behavior of Carbon Fiber‐Reinforced Thermoplastic Composites for Type V Hydrogen Storage Tanks: Effects of Hygrothermal Aging on Physicochemical and Mechanical Properties

Polymer Composites, EarlyView.
Hygrothermal aging behavior of CF/PPA composite. ABSTRACT This study investigates the hygrothermal aging behavior of carbon fiber‐reinforced polyphthalamide (CF/PPA) composites used in Type V hydrogen tanks, which are exposed to humid environments during service.

A Gaussian Process Regression IV Model for PV Outdoor Data

Progress in Photovoltaics: Research and Applications, EarlyView.
Each electrical performance measure of PV modules needs to be considered in the context of dynamically changing outdoor conditions. In this paper, we introduce a statistical model based on Gaussian process regressions designed to analyze PV outdoor data aiming to utilize all available information.

Relation of Bulk‐to‐Shear Loss Factors in Viscoelastic Auxetic Metamaterials

physica status solidi (b), EarlyView.
This article examines the dynamic behavior of isotropic auxetic viscoelastic materials, highlighting how negative Poisson's ratios affect energy dissipation, damping, and the interplay between bulk and shear moduli. By extending established viscoelastic theories to the auxetic range, it defines bound limits and underscores how dynamic Poisson's ratio ...

Mapping Thermal Conductivity at the Atomic Scale: A Step toward the Thermal Design of Materials

physica status solidi (b), EarlyView.
The site‐projected thermal conductivity method resolves the local thermal conduction contribution per atom by decomposing the Green–Kubo thermal conductivity tensor under the harmonic approximation. It highlights thermally active sites and “thermal defects” within disordered or amorphous materials, enabling spatially resolved insights into atomic‐scale

A conservative numerical scheme for the multilayer shallow‐water equations on unstructured meshes

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An energy‐conserving scheme is derived for the multilayer shallow water model, making use of the direct connection between energy conservation and the skew symmetry of the Poisson bracket for the model. A new mechanism is proposed to prevent layer interface outcropping.

Toward Useful Quantum Kernels

Advanced Quantum Technologies, EarlyView.
The hybrid approach to Quantum Supervised Machine Learning is compatible with Noisy Intermediate Scale Quantum (NISQ) devices but hardly useful. Pure quantum kernels requiring fault‐tolerant quantum computers are more promising. Examples are kernels computed by means of the Quantum Fourier Transform (QFT) and kernels defined via the calculation of ...

Proper Implicit Discretization of Arbitrary‐Order Robust Exact Differentiators—Without and With Noise Filtering

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper considers the implicit Euler discretization of Levant's arbitrary order robust exact differentiator (RED) and Levant and Livne's arbitrary order robust exact filtering differentiator in the presence of sampled measurements.

Optical Micromanipulations Based on Model Predictive Control of Thermoviscous Flows

Small, EarlyView.
Optofluidic manipulations of colloids are enabled by model predictive control of laser‐induced thermoviscous flows. This method is shown to be successful in controlling up to nine microparticles in both deterministic simulations and experiments via the sequential application of analytically tractable flow fields.

Thermosensitive Nanostructured Coacervates Developed by Mixing ABA‐ and AB‐Block Copolymers and Their Unique Sustained Release of Nano‐Micelles in a Regulated Manner

Small, EarlyView.
Polyion complex micelles composed of blends of ABA and AB block copolymers can form coacervates with a hexagonally packed cylinder nanostructure after heating. The resulting coacervates can release the micelles under physiological conditions in a zero‐order kinetics, possessing cargo proteins.
