Influence of Laser Strategies on Performance of Lattice Structures from Magnesium Alloy WE43 Produced by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, Volume 27, Issue 7, April 2025.
The body‐centered‐cubic lattice structures from magnesium alloy WE43 with high relative material density (99.5%), fine microstructure, high mechanical properties (effective elastic modulus of 136 MPa), and material properties (Young's modulus of 40 GPa) are produced by laser beam powder bed fusion using hatch strategy with skywriting.

Fully Coupled Forward-backward Stochastic Differential Equations on Markov Chains [PDF]

arXiv, 2015
We define fully coupled forward-backward stochastic differential equations on spaces related to continuous time, finite state Markov Chains. Existence and uniqueness results of the fully coupled forward-backward stochastic differential equations on Markov Chains are obtained.

Static Recrystallization Simulation of Interstitial Free‐Steel by Coupling Multi‐Phase‐Field and Crystal Plasticity Model Considering Dislocation Density Distribution

Advanced Engineering Materials, EarlyView.
This study models static recrystallization in interstitial free‐steel using coupled crystal plasticity and phase‐field simulations. The method directly links heterogeneous dislocation density to nucleation site prediction, eliminating reliance on empirical assumptions.

Mixed Effects in Stochastic Differential Equation Models

Revstat Statistical Journal, 2005
A class of statistical models is proposed where random effects are incorporated into a stochastic differential equations model, and an expression for the likelihood function is derived.

Structurally Colored Physically Unclonable Functions with Ultra‐Rich and Stable Encoding Capacity

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reports a design strategy for generating bright‐field resolvable physically unclonable functions with extremely rich encoding capacity coupled with outstanding thermal and chemical stability. The optical response emerges from thickness‐dependent structural color formation in ZnO features, which are fabricated by physical vapor deposition ...
