Mathematical Problems in Engineering, Volume 2003, Issue 1, Page 25-45, 2003., 2003 We extend the notion of dissipative dynamical systems to formalize the concept of the nonlinear analog of strict positive realness and strict bounded realness. In particular, using exponentially weighted system storage functions with appropriate exponentially weighted supply rates, we introduce the concept of exponential dissipativity.

Multiple Private Set Intersection From Reusable Oblivious PRF
Security and Communication Networks, Volume 2025, Issue 1, 2025.Private set intersection (PSI) is a technique that enables two or multiple parties to find their common elements while keeping all other data confidential and hidden. The research on two‐party PSI has been well‐developed. However, their dataset is often updated dynamically.

Complex coupled system dynamics and the global warming policy problem
Discrete Dynamics in Nature and Society, Volume 7, Issue 2, Page 93-100, 2002., 2002 A Public Domain, once a velvet carpet of rich buffalo‐grass and grama, now an illimitable waste of rattlesnake‐bush and tumbleweed, too impoverished to be accepted as a gift by the states within which it lies. Why? Because the ecology of this Southwest happened to be set on a hair trigger.—Aldo Leopold. 1933. The Conservation Ethic. Journal of Forestry

European Journal of Organic Chemistry, Volume 27, Issue 43, November 18, 2024.The vicinal (hetero)aryl functionalization of unactivated alkenes through radical addition of a functional group followed by remote (hetero)aryl migration provides a valuable tactic to install an aromatic ring at a specific position. The migratory (hetero)aromatic ring can be initially tethered to either the alkene or the radical precursor. This review

Hydroxytrifluoroethylation and Trifluoroacetylation Reactions via SET Processes
Chemistry – A European Journal, Volume 30, Issue 18, March 25, 2024.In this review we present the recent methods available in the literature for the direct introduction of hydroxytrifluoroethyl and trifluoroacetyl groups in organic molecules governed by single‐electron transfer processes. Abstract Hydroxytrifluoroethyl and trifluoroacetyl groups are of utmost importance in biologically active compounds, but methods to ...
