Existence of General Competitive Equilibria: A Variational Approach

Abstract and Applied Analysis, 2016
We study the existence of general competitive equilibria in economies with agents and goods in a finite number. We show that there exists a Walras competitive equilibrium in all ownership private economies such that, for all consumers, initial endowments

Engineering Metal‐Pocket Cooperativity in Single‐Atom COF Nanozymes for Selective Cascade Catalysis

Advanced Materials, EarlyView.
A multilevel programming strategy is developed to engineer single‐atom COF nanozymes with tunable metal centers and chiral pockets inspired by heme–pocket cooperativity. This approach enables controlled metal–pocket interplay for asymmetric cascade catalysis, delivering high activity, selectivity, and recyclability in an asymmetric oxidation–aldol ...

SecurePoL: Integration of Watermarking With Proof-of-Learning to Enhance Security Against Spoofing Attacks

IEEE Access
Proof-of-Learning (PoL) attests training effort but remains vulnerable to tolerance-based spoofing, while model watermarking (WM) protects ownership without verifying how a model was trained.
