A Splitting Architecture for Exact Reduced Coulomb Friction

open access: yesComputer Graphics Forum, EarlyView.
Abstract Existing approaches to frictional contact dynamics typically either modify the Coulomb law to improve numerical robustness or solve the exact law in a fully coupled monolithic form. However, in its reduced form, exact Coulomb friction can be written as a cone complementarity problem with an augmented velocity, which reveals a natural split ...

Decomposition of Distributed Nonmonotonic Multi-Context Systems [PDF]

open access: yes, 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 ...

Longevity, Health, and Housing Risk Management in Retirement

open access: yesThe Journal of Finance, EarlyView.
ABSTRACT Annuities, long‐term care insurance, and reverse mortgages remain puzzlingly unpopular to manage post‐retirement longevity, health, and housing price risks. We use a flexible life‐cycle model structurally estimated with a unique stated‐preference survey experiment of Canadian households to understand why. Key factors include high risk aversion,

Sequential Outlier Detection in Nonstationary Time Series

open access: yesJournal 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

Spatial dynamics for a non-monotone reaction-diffusion system with spatio-temporal delay

open access: yesMathematics in Applied Sciences and Engineering
In 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 ...

Valid Data‐Driven Subgroup Selection With Uniform Guarantees in Clinical Trials

open access: yesStatistics in Medicine, Volume 45, Issue 23-24, October 2026.
ABSTRACT Subgroup selection in clinical trials is essential for identifying patient groups that react differently to a treatment, thereby enabling personalized medicine. In particular, subgroup selection can identify patient groups that respond particularly well to a treatment or that encounter adverse events more often.

Minimal wave speed on a diffusive SIR model with nonlocal delays

open access: yesElectronic 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

Pairwise Imitation and Tournament Graphs

open access: yesInternational Economic Review, Volume 67, Issue 3, Page 937-955, August 2026.
ABSTRACT This paper investigates strategic dynamics under the behavioral rule of pairwise interact and imitate (PII), which requires minimal information and emphasizes outperforming opponents in pairwise interactions. We characterize PII using weak tournament graphs and, for a broad class of dynamics, establish a one‐shot stability result for ...

Convergence in comparable almost periodic reaction-diffusion systems with Dirichlet boundary conditions

open access: yesElectronic Journal of Differential Equations, 2014
In this article, we study the asymptotic dynamics in nonmonotone comparable almost periodic reaction-diffusion systems with Dirichlet boundary condition, which are comparable with uniformly stable strongly order-preserving system.

A Model of Punitive Voting

open access: yesJournal of Public Economic Theory, Volume 28, Issue 4, August 2026.
ABSTRACT I analyze a two‐period model of political competition where voters care about candidates' integrity. Candidates must trade off implementing their preferred policy against maintaining their electoral promises. Voters punish candidates who deviate from electoral promises by voting for their opponent.
