A Differentiable Formulation of a Set‐Valued Force Law Approximating Planar Coulomb Friction and Its use in Optimal Control

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT In this paper, we present a regularization of the set‐valued Coulomb friction law based on a regularized projection. The regularized projection is used to formulate differentiable equations encoding a set‐valued friction law that can be used in typical optimal control frameworks.

Differences in Phenylpropanoid and Reactive Oxygen Species Genes Drive Plastic and Adaptive Responses to Drought Stress Between Douglas‐Fir Varieties and Hybrids

Plant Direct, Volume 10, Issue 3, March 2026.
ABSTRACT Warming climates bring significant challenges to the survival and growth of conifer species, yet the genomic basis of drought resistance is poorly understood. In this study, we used a common garden experiment to combine genomic, physiological and transcriptomic analysis to dissect plastic and adaptive responses to drought between Douglas‐fir ...

Numerical Simulations of Very Low Velocity Impacts and Ignition of an Explosive Confined by a Thin Case

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 3, Page 446-455, March 2026.
A low‐speed impact (around one meter per second) of a metallic tip on an explosive confined by a thin plate is simulated. The heat due to friction between the tip and the plate and the one due to the deformation of the plate are not transfered to the ignited zone.

Step‐Ladder Bioprinting to Align Collagen Fibers for Anisotropic Tissue Fabrication

Small, Volume 22, Issue 13, 3 March 2026.
The step‐ladder printing platform includes successive segments of channels with varying widths in a custom barrel design. This design allows for improved anisotropy of collagen fibers during extrusion. To demonstrate its effectiveness, corneal constructs with high transparency and shape fidelity, as well as articular cartilage constructs, displaying ...

Effects of Pyrolysis Control Parameters on the Structural Properties of Biomass‐Derived Activated Carbon Materials and Their Energy Applications

The Chemical Record, Volume 26, Issue 3, March 2026.
Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...

The Functional Delta Method for Deriving Asymptotic Distributions

WIREs Computational Statistics, Volume 18, Issue 1, March 2026.
The distribution of the scaled difference between the plug‐in estimator Tθ̂n$$ T\left({\hat{\boldsymbol{\theta}}}_n\right) $$ and the true parameter Tθ0$$ T\left({\boldsymbol{\theta}}_0\right) $$ is approximated by the distribution of the scaled difference between θ̂n$$ {\hat{\boldsymbol{\theta}}}_n $$ and θ0$$ {\boldsymbol{\theta}}_0 $$ and a ...
