Wavefront Shaping for Optimal Extinction of Focused Light by Individual Nanoscatterers

open access: yesLaser &Photonics Reviews, EarlyView.
Wavefront shaping enables near‐complete optical extinction by nanoscatterers separated from a planar reflector. Time‐reversed emission profiles provide optimal illumination conditions, yielding 70% extinction from a single plasmonic nanoparticle and up to 90% from sub‐wavelength nanoparticle clusters, offering a promising route to efficient in‐ and out‐

Photonic Neuromorphic Processing With Coupled Spiking Silicon Microrings

open access: yesLaser &Photonics Reviews, EarlyView.
A neuromorphic photonic core composed of three self‐pulsing silicon microring resonators is experimentally demonstrated for analogue and digital processing. Richer computational capabilities emerge under injection conditions where the dynamics are nonlinear and coupled, yet remain reproducible, opening novel strategies for future on‐chip training and ...

Almost Periodicity on Isolated Time Scales and Applications

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT In this work, we formulate a generalized definition of almost periodicity for functions defined on isolated time scales. The introduced definition is consistent with the known formulations in the discrete and quantum calculus settings. We state two different definitions of almost periodicity and we show their relation.

Nonconstant Positive Steady States for a Predator–Prey System With Signal‐Dependent Diffusion

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT This paper investigates a highly nonlinear predator–prey reaction–diffusion system featuring signal‐dependent prey diffusion, where the motility of the prey is modulated by a chemical signal released by predators. For unbounded functional responses, we establish the global‐in‐time existence and uniform‐in‐time boundedness of classical ...

Graded Differential Polynomial Rings

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT We study differential polynomial rings R[t;δ]$R[t;\delta]$ over Γ$\Gamma$‐graded rings, where Γ$\Gamma$ is an arbitrary group. We show that R[t;δ]$R[t;\delta]$ admits a Γ$\Gamma$‐grading compatible with that of R$R$ if and only if δ$\delta$ is a γ$\gamma$‐derivation for some γ∈CΓ(ΓR)$\gamma \in C_\Gamma (\Gamma _R)$, and that this grading is ...
