Invasion Generates Periodic Traveling Waves (Wavetrains) in Predator-Prey Models with Nonlocal Dispersal [PDF]
, 2016 Periodic Traveling waves (wavetrains) have been studied extensively in systems of reaction-diffusion equations. An important motivation for this work is the identification of periodic Traveling waves of abundance in ecological data sets.

Revealing Hidden Raman Signatures Through Attention‐Based Spectral Unmixing
Advanced Intelligent Systems, EarlyView.Weak Raman signatures are recovered from background‐dominated spectra using a transformer‐based, reference‐free spectral unmixing AI framework. Self‐attention reconstructs substrate contribution directly from mixed data, enabling reliable extraction of previously inaccessible vibrational features.

TRAVELING WAVE SOLUTIONS IN NONLOCAL DISPERSAL MODELS WITH NONLOCAL DELAYS [PDF]
Journal of the Korean Mathematical Society, 2014 This paper is concerned with the traveling wave solutions of nonlocal dispersal models with nonlocal delays. The existence of traveling wave solutions is investigated by the upper and lower solutions, and the asymptotic behavior of traveling wave solutions is studied by the idea of contracting rectangles.

‘Nonlocal’ dispersion cancelation with classical light [PDF]
New Journal of Physics, 2009 We show a classical analog of the original nonlocal dispersion cancelation effect in intensity interferometry with stationary light obeying Gaussian statistics. The dispersion compensation is due to the uncorrelation of the spectral components of the radiation.

Dynamics of a nonlocal dispersal SIS epidemic model
Communications on Pure and Applied Analysis, 2017 This paper is concerned with a nonlocal dispersal susceptible-infected-susceptible (SIS) epidemic model with Dirichlet boundary condition, where the rates of disease transmission and recovery are assumed to be spatially heterogeneous. We introduce a basic reproduction number $R_0$ and establish threshold-type results on the global dynamic in terms of ...

Internationalization and ESG Controversies: Do Foreign Directors on Corporate Boards Matter?
Business Strategy and the Environment, EarlyView.ABSTRACT This study examines the relationship between internationalization and environmental, social, and governance (ESG) controversies, focusing on whether foreign directors on corporate boards influence this relationship. Drawing on resource dependence theory, we argue that internationalization increases ESG controversies due to the complexity of ...

Electronic Journal of Differential EquationsThis article concerns the traveling wavefronts of a discrete diffusive Lotka-Volterra competition system with nonlocal nonlinearities. We first prove that there exists a \(c_*>0\) such that when the wave speed is large than or equals to \(c_*\), the ...

Nonlocal cancellation of dispersion in Franson interferometry [PDF]
Physical Review A, 2013 Dispersion and its cancellation in entanglement-based nonlocal quantum measurements are of fundamental and practical interests. We report the first demonstration of cancellation of femtosecond-level dispersion by inverting the sign of the differential dispersion between the long and short paths in only one arm of a fiber-based Franson interferometer ...
