Strong Stability for a Viscoelastic Transmission Problem Under a Nonlocal Boundary Control
AxiomsThe purpose of this paper is to consider a transmission problem of a viscoelastic wave with nonlocal boundary control. It should be noted that the present paper is based on the previous C. G. Gal and M. Warma works, together with H. Atoui and A. Benaissa.

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces
InfoMat, EarlyView.A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

New Drain Spacing Formulas Using the Variational Iteration Method
Irrigation and Drainage, EarlyView.ABSTRACT In this study, the drain spacing is computed using the variational iteration method (VIM) to the linearized Boussinesq equation. By applying at most two iterations of the VIM method under three different initial condition scenarios, three equations for drain spacing calculation were derived. These equations predict values of drain spacing that

Control and State Estimation of the One-Phase Stefan Problem via Backstepping Design
, 2017 This paper develops a control and estimation design for the one-phase Stefan problem. The Stefan problem represents a liquid-solid phase transition as time evolution of a temperature profile in a liquid-solid material and its moving interface.

Nonlinear multidimensional parabolic-hyperbolic equations
Electronic Journal of Differential Equations, 2007 This paper deals with the coupling of a quasilinear parabolic problem with a first order hyperbolic one in a multidimensional bounded domain $Omega$. In a region $Omega_{p}$ a diffusion-advection-reaction type equation is set while in the complementary ...

Design of polychromatic focusing optics for neutron reflectometers: rethinking REFocus optics
Journal of Applied Crystallography, EarlyView.REFocus optics, employing an elliptical mirror and higher‐order reflections, enable rapid wide‐Q‐range neutron reflectometry at reactor sources, achieving up to 100‐fold faster measurements compared with conventional methods.Neutron reflectometry is a widely used non‐destructive technique for analyzing surface and interfacial structures. In this study,

Enchanting the Otherwise: Magical Realism and the Gendered Ontologies of Organizational Becoming
Gender, Work &Organization, EarlyView.ABSTRACT This paper enacts a feminist‐posthumanist reimagining of gender as ontological disturbance, using magical realism not as metaphor but as epistemological method. Rejecting representational logics and the managerial rationalities of organizational realism, we advance gender not as identity or role but as spectral interference—a transversal ...
