A System for Nonmonotonic Rules on the Web
, 2004 Defeasible reasoning is a rule-based approach for efficient reasoning with incomplete and inconsistent information. Such reasoning is, among others, useful for ontology integration, where conflicting information arises naturally; and for the modeling of business rules and policies, where rules with exceptions are often used.

An analytical model of search and bargaining with divisible money
Theoretical Economics, Volume 20, Issue 2, Page 713-761, May 2025.We propose a standard search and bargaining model with divisible money, in which only the random matching market opens and the generalized Nash bargaining settles each trade. Assuming fixed production costs, we analytically characterize a tractable equilibrium, called a pay‐all equilibrium, and prove its existence. Each buyer pays all the money holding

Econometrica, Volume 93, Issue 2, Page 623-659, March 2025.Is more novel research always desirable? We develop a model in which knowledge shapes society's policies and guides the search for discoveries. Researchers select a question and how intensely to study it. The novelty of a question determines both the value and difficulty of discovering its answer.

Schatten-$p$ Quasi-Norm Regularized Matrix Optimization via Iterative Reweighted Singular Value Minimization [PDF]
, 2016 In this paper we study general Schatten-$p$ quasi-norm (SPQN) regularized matrix minimization problems. In particular, we first introduce a class of first-order stationary points for them, and show that the first-order stationary points introduced in [11]

A PDMS/Silicon Adhesion Control Method at Millimeter‐Scale Based on Microvibration
Advanced Intelligent Systems, Volume 7, Issue 2, February 2025.This article explores the application of adhesion hysteresis in small‐scale adhesion devices using microvibration and PDMS/Si contact. It examines key factors such as vibration amplitude, frequency, surface roughness, size, and Young's modulus and their contributions to optimizing adhesion performance. A numerical model and practical gripper models are

Studies in Applied Mathematics, Volume 154, Issue 2, February 2025.ABSTRACT In this paper, we investigate the existence and uniqueness of the semi‐wave solution to a bistable delayed reaction–diffusion equation with a double free boundary. This equation captures key features of biological systems and has broad applications in mathematical biology, including population dynamics, gene expression, virus propagation, and ...

Spreading Speed, Traveling Waves, and Minimal Domain Size in\ud Impulsive Reaction-diffusion Models [PDF]
, 2012 How growth, mortality, and dispersal in a species affect the species’ spread and persistence constitutes a central problem in spatial ecology. We propose impulsive reaction-diffusion equation models for species with distinct reproductive and dispersal ...

Nonmonotonic Aging and Memory Retention in Disordered Mechanical Systems
Physical Review Letters, 2017 We observe non-monotonic aging and memory effects, two hallmarks of glassy dynamics, in two disordered mechanical systems: crumpled thin sheets and elastic foams. Under fixed compression, both systems exhibit monotonic non-exponential relaxation. However, when after a certain waiting time the compression is partially reduced, both systems exhibit a non-

Convergence and nonconvergence in a nonlocal gradient flow
Journal of the London Mathematical Society, Volume 111, Issue 1, January 2025.Abstract We study the asymptotic convergence as t→∞$t\rightarrow \infty$ of solutions of ∂tu=−f(u)+∫f(u)$\partial _t u=-f(u)+\int f(u)$, a nonlocal differential equation that is formally a gradient flow in a constant‐mass subspace of L2$L^2$ arising from simplified models of phase transitions. In case the solution takes finitely many values, we provide
