Speckle‐Engineered Upconversion Amplification in Nanoemulsion‐Templated Hydrogel Microdomes
Advanced Functional Materials, EarlyView.Nanoemulsion‐confined PEGDA microdomes generate speckle‐like excitation fields that strongly amplify upconversion luminescence upon dehydration, enabling filter‐free visible readout with reversible on–off switching. DMD‐based lithography yields scalable, shape‐programmable arrays for moisture‐responsive displays and optical encryption.

Convergence Properties for Discrete-Time Nonlinear Systems [PDF]
IEEE Transactions on Automatic Control, 2019 Three similar convergence notions are considered. Two of them are the long established notions of convergent dynamics and incremental stability. The other is the more recent notion of contraction analysis. All three convergence notions require that all solutions of a system converge to each other.

Discrete Breathers in Two-Dimensional Anisotropic Nonlinear Schrodinger lattices
, 2006 We study the structure and stability of discrete breathers (both pinned and mobile) in two-dimensional nonlinear anisotropic Schrodinger lattices. Starting from a set of identical one-dimensional systems we develop the continuation of the localized ...

Controllability of nonlinear discrete systems [PDF]
Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002 1-D and 2-D discrete-time nonlinear stationary dynamic systems are considered. Local controllability conditions for unconstrained controls that have been previously derived are extended to the constrained controls case.
