No‐regret and low‐regret control for a weakly coupled abstract hyperbolic system
Asian Journal of Control, EarlyView.Abstract This paper explores an optimal control problem of weakly coupled abstract hyperbolic systems with missing initial data. Hyperbolic systems, known for their wave‐like phenomena and complexity, become even more challenging with weak coupling between subsystems.

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract This paper presents a novel technology for converting glycerol, a byproduct of the biodiesel industry, into glycerol carbonate, a high‐value bioproduct. The effect of calcination temperature on the synthesis of quaternary Cu‐Ni‐Mg‐Al catalysts (MMO‐Cu15Ni15‐Tz) and their application in the transesterification reaction was investigated ...

ChemistryEurope, EarlyView.Using density functional theory calculations, and by comparing calculated gas‐phase formation energies, bulk cohesive energies, lattice constants, and nitrogen and ammonia adsorption energies on Fe and Fe‐nitride surfaces to experimental estimates, the accuracy of several XC functionals is assessed for modeling iron‐catalyzed ammonia synthesis. Density

Legendre-Tau approximations for functional differential equations [PDF]
The numerical approximation of solutions to linear functional differential equations are considered using the so called Legendre tau method. The functional differential equation is first reformulated as a partial differential equation with a nonlocal ...

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

A review of multiscale numerical modeling of rock mechanics and rock engineering
Deep Underground Science and Engineering, EarlyView.Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...
