Computing abstractions of nonlinear systems

, 2011
Sufficiently accurate finite state models, also called symbolic models or discrete abstractions, allow one to apply fully automated methods, originally developed for purely discrete systems, to formally reason about continuous and hybrid systems, and to ...

Digital Microneedles for Multiplexed Transdermal Sensing via Fluorescent QR Codes

Advanced Materials, EarlyView.
Digital fluorescent microneedles encode biochemical information in skin into scannable QR codes through threshold‐activated probes that generate binary on/off signals. By transforming analog fluorescence into discrete digital patterns, this platform enables calibration‐free, multiplexed transdermal sensing of physiologically relevant biomarkers ...

Population systems with nonlinear discrete diffusion terms

Journal of Mathematical Analysis and Applications, 2003
The authors investigate the asymptotic behavior of the period population system with nonlinear discrete diffusion terms \[ \begin{aligned} x_i'&= D_i(t,x_1,\ldots,x_n)+ x_if_i(t,x_i,y_i),\\ y_i'&= E_i(t,y_1,\ldots,y_n)+y_ig_i(t,x_i,y_i), \end{aligned}\quad 1\leq i\leq n, \] where \(f_i,g_i: \mathbb{R}\times \mathbb{R}_+^2\rightarrow \mathbb{R}\) are ...
