Communications on Pure and Applied Mathematics, EarlyView.Abstract Let (Mn,g)$(M^n,g)$ be a complete Riemannian manifold which is not isometric to Rn$\mathbb {R}^n$, has nonnegative Ricci curvature, Euclidean volume growth, and quadratic Riemann curvature decay. We prove that there exists a set G⊂(0,∞)$\mathcal {G}\subset (0,\infty)$ with density 1 at infinity such that for every V∈G$V\in \mathcal {G}$ there ...

Communications on Pure and Applied Mathematics, EarlyView.Abstract We analyse and clarify the finite‐size scaling of the weakly‐coupled hierarchical n$n$‐component |φ|4$|\varphi |^4$ model for all integers n≥1$n \ge 1$ in all dimensions d≥4$d\ge 4$, for both free and periodic boundary conditions. For d>4$d>4$, we prove that for a volume of size Rd$R^{d}$ with periodic boundary conditions the infinite‐volume ...

Energy Landscapes in Chemical Reactions and Transport
ChemPhysChem, Volume 26, Issue 6, March 15, 2025.Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

Magnetization and Polarization of Coupled Nuclear Spins Ensembles at High Magnetic Fields
ChemPhysChem, EarlyView.Herein, the magnetization of spins at high magnetic fields using various theoretical approaches is analyzed. The theorem is rigorously proved that the magnetization of individual spins is equivalent to the magnetization of coupled spins within a molecule.

International Journal of Circuit Theory and Applications, EarlyView.For the series active filter (SAF), a combined controller and observer scheme is proposed. Two controllers—state feedback (SFB) and linear quadratic regulator (LQR)—along with state observers, including the Luenberger observer (LO), proportional–integral observer (PIO), and unknown input observer (UIO), have been designed.

International Journal of Circuit Theory and Applications, EarlyView.This study focused on reducing the simulation counts required for circuit sizing by optimizing the initial population selection in evolutionary algorithms. We investigated the impact of different sampling methods on the efficiency of multi‐objective optimization based on differential evolution and Bayesian inference, a leading algorithm in circuit ...
