Association of Neighborhood Deprivation With Breslow Thickness in Head and Neck Cutaneous Melanoma

open access: yesThe Laryngoscope, EarlyView.
Neighborhood socioeconomic deprivation, measured by the Area Deprivation Index (ADI), was independently associated with greater Breslow thickness in patients with primary head and neck cutaneous melanoma treated at a single tertiary care center. Patients residing in the most deprived neighborhoods had, on average, 1.40 mm greater tumor thickness ...

Land Restoration as a Catalyst for Regional Economic Revitalization: Evidence From Urban–Rural Transition Zones

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Large‐scale land restoration is widely expected to improve environmental quality, yet causal evidence on its local economic returns remains limited. This gap is especially important in urban–rural transition zones, where development pressure and ecological damage overlap.

Quantization of Polaritons Confined in Dielectric Structures

open access: yesLaser &Photonics Reviews, EarlyView.
This study addresses the limitations of the Hopfield model of strong light‐matter coupling in the case of structured dieletrics. A method to derive quantum models in the polariton basis using Bogoliubov transformation and third quantization is introduced, demonstrating how to boost interaction strength and engineer nonlocal interactions for strongly ...

Theory of Supercritical Coupling and Generalized Bound States in the Continuum

open access: yesLaser &Photonics Reviews, EarlyView.
We develop a general theory of supercritical coupling and generalized bound states in the continuum (gBICs), revealing how interference between radiative and absorptive channels enables quality factors beyond conventional material‐loss limits. The framework unifies non‐Hermitian mode coupling, causality‐driven reactive interactions, and interference ...

Hilbert's Basis Theorem for Poisson Ore Extensions

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT We prove an analogue of Hilbert's basis theorem for Poisson Ore extensions and Poisson Laurent Ore extensions. We also obtain corresponding results for iterated Poisson Ore extensions and iterated Poisson Laurent Ore extensions associated to commuting Poisson‐pairs.

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.

A Geometric Interpretation for the Algebraic Properties of Second‐Order Ordinary Differential Equations

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6912-6917, April 2025.
ABSTRACT Nowadays, a substantial portion of investigations concerning the symmetry analysis of differential equations predominantly adhere to a framework comprising the following key procedures: (i) the derivation of symmetries, (ii) the determination of an optimal system, (iii) the utilization of these symmetries to construct invariants or ...

Diagnostic des systèmes à commutation : identification de la loi de commutation

open access: yes, 2005
National audienceLes systèmes à commutation représentent une classe particulière de systèmes hybrides. Ils sont décrits par plusieurs modèles de fonctionnement et chaque modèle, appelé mode du système, est actif sous certaines conditions opératoires ...

Markov‐Associated Quadratic Stochastic Families and the Susceptible‐Infected‐Recovered (SIR) Model

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We introduce a Markov‐associated construction for quadratic stochastic families generated by a symmetric cubic stochastic matrix and a finite‐state homogeneous Markov semigroup. The constructed family is not assumed to be a classical quadratic stochastic process of type (A)$$ (A) $$ or type (B)$$ (B) $$; rather, it is a Markov‐associated ...
