A System for Nonmonotonic Rules on the Web

open access: yes, 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.

Well-Founded Semantics for Extended Datalog and Ontological Reasoning [PDF]

open access: yes, 2013
The Datalog± family of expressive extensions of Datalog has recently been introduced as a new paradigm for query answering over ontologies, which captures and extends several common description logics.

Abstraction of Prevention Conceived in Distributed Knowledge Base

open access: yesInternational Conference on Complex Information Systems, 2023
: This paper is concerned with prevented information common in distributed knowledge base. The distributed knowledge is a framework to reflect knowledge acquisition and retrieval in a seminar class with participants. The presented accounts are listened to,

Payoff-driven coevolution and oscillatory dynamics in hypergraph [PDF]

open access: yesChaos, Solitons & Fractals
We study a coevolutionary public goods game on a dynamic hypergraph, where an individual's payoff directly determines the number of hyperedges it can join.

An Intelligent AIEgen with Nonmonotonic Multi-Responses to Multi-Stimuli [PDF]

open access: yes, 2020
Intelligent stimulus-response (S/R) systems are the basis of natural process and machine control, and have been intensively explored in biomimetic design, analytical chemistry and biological applications. However, nonmonotonic multi-S/R systems are still

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Embedded Ferroelectric Nanoclusters Can Drive Polarization Reversal in a Non‐Ferroelectric Polar Film via the Proximity Effect

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.

Disorder‐Broadened Topological Hall Phase and Anomalous Hall Scaling in FeGe

open access: yesAdvanced Functional Materials, EarlyView.
By systematically introducing defects into FeGe via ion‐beam modification, we demonstrate that disorder broadens the temperature regime over which the topological Hall effect ‐ a signature of skyrmions or other chiral textures — appears, while also increasing its magnitude.
