Decomposition of Distributed Nonmonotonic Multi-Context Systems [PDF]
, 2010 Multi-Context Systems (MCS) are formalisms that enable the inter-linkage of single knowledge bases, called contexts, via bridge rules. Recently, a fully distributed algorithm for evaluating heterogeneous, nonmonotonic MCS was described in [7]. In this paper, we continue this line of work and present a decomposition technique for MCS which analyzes the ...

Sequential Outlier Detection in Nonstationary Time Series
Journal of Time Series Analysis, EarlyView.ABSTRACT A novel method for sequential outlier detection in nonstationary time series is proposed. The method tests the null hypothesis of “no outlier” at each time point, addressing the multiple testing problem by bounding the error probability of successive tests, using extreme‐value theory. The asymptotic properties of the test statistic are studied

Risk Analysis, Volume 46, Issue 7, July 2026.ABSTRACT Artificial intelligence (AI) is reshaping national economies, yet country‐level AI–macro relationships remain poorly understood. Using annual data for the United States and China, 1980–2020, we develop a four‐layer triangulation framework—Pattern Causality, Granger causality, VECM‐based cointegration, and lead–lag correlation—to map ...

Spatial dynamics for a non-monotone reaction-diffusion system with spatio-temporal delay
Mathematics in Applied Sciences and EngineeringIn this paper, we study the spreading speed and traveling wave solutions of a non-monotone reaction-diffusion system with spatio-temporal delay. By constructing a pair of auxiliary systems and using the Schauder 's fixed point theorem, the existence of ...

Arthritis &Rheumatology, Volume 78, Issue 6, Page 1258-1267, June 2026.Objective The multinational, phase 3, double‐blind, placebo‐controlled TULIP‐SC trial evaluated the efficacy and safety of subcutaneous anifrolumab in adults who have moderate to severe systemic lupus erythematosus (SLE) activity, despite receiving standard therapy. Methods Adults with SLE received subcutaneous anifrolumab 120 mg or placebo once weekly

Monotonicity and Robust Implementation Under Forward‐Induction Reasoning
Econometrica, Volume 94, Issue 2, Page 505-536, March 2026.In sequential games, the set of paths consistent with rationality and forward‐induction reasoning may change nonmonotonically when adding transparent restrictions on players' beliefs. Yet, we prove that—in an incomplete‐information environment—predictions become sharper when the restrictions only concern initial beliefs about types.

Minimal wave speed on a diffusive SIR model with nonlocal delays
Electronic Journal of Differential Equations, 2018 This article concerns the minimal wave speed of a diffusive SIR model with nonlocal delays, in which the dynamics of disease has no positive outbreak threshold. By constructing a pair of super and sub-solutions, we establish the existence of traveling

Asymptotic Profiles and Disease Prevalence at the Steady State for an SIS Patch Model
Studies in Applied Mathematics, Volume 156, Issue 1, January 2026.ABSTRACT Infected individuals often display mobility patterns that differ significantly from those of healthy individuals—traveling less frequently, covering shorter distances, visiting fewer destinations, and altering their timing and modes of movement.

Abstract and Applied Analysis, Volume 2026, Issue 1, 2026.This paper investigates the application of β‐open sets to the convergence analysis of nonautonomous evolution equations governed by maximal monotone operators in Hilbert spaces. β‐open sets are a class of generalized open sets introduced by Njåstad (1965), which coincides with the class of semiopen sets by Levine (1963).
