Algebraic Proof Systems (Invited Talk)

open access: yes, 2021
Given a set of polynomial equations over a field F, how hard is it to prove that they are simultaneously unsolvable? In the last twenty years, algebraic proof systems for refuting such systems of equations have been extensively studied, revealing close ...

A general theory of action languages

open access: yes, 1998
We present a general theory of action-based languages as a paradigm, for the description, of those computational systems which include elements of concurrency and networking, and extend this approach to describe dist.ributed systems and also t,o ...

How are educational interventions delivered at scale? A systematic mapping review

open access: yesReview of Education, Volume 14, Issue 2, August 2026.
Abstract Scaling up educational interventions remains a central yet under‐theorised challenge in educational research. Although conceptual frameworks outline principles for successful scale‐up, evidence on how scaling is operationalised in practice has not been systematically synthesised.

Concurrency and automata on infinite sequences [PDF]

open access: yes
The paper is concerned with ways in which fair concurrency can be modeled using notations for omega-regular languages - languages containing infinite sequences, whose recognizers a.re modified forms of Buchi or Muller-McNaughton automata.

A Multivariate Mixed‐Effects Regression Framework for Ground Motion Modeling: Integrating Parametric and Machine Learning Approaches

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1811-1827, 25 July 2026.
ABSTRACT Multivariate ground motion models (GMMs) that capture the correlation between different intensity measures (IMs) are essential for seismic risk assessment. Conventional GMMs are often developed using a two‐stage approach, where separate univariate models with predefined functional forms are fitted first, and correlation is addressed in a ...

Applications of algebraic automata theory to quantum finite automata

open access: yes, 2007
The computational model of Quantum Finite Automata has been introduced by multiple authors (e.g. [38, 44]) with some variations in definition. The objective of this thesis is to understand what class of languages can be recognized by these different ...

What Are Asset Price Bubbles? A Survey on Definitions of Financial Bubbles

open access: yesJournal of Economic Surveys, Volume 40, Issue 3, Page 1572-1592, July 2026.
ABSTRACT Financial bubbles and crashes have repeatedly caused economic turmoil notably but not just during the 2008 financial crisis. However, both in the popular press as well as scientific publications, the meaning of bubble is sometimes unspecified.

A Thermodynamic 3D Model for the Simulation of Diffusion‐Controlled Alloying Processes in Heterogeneous Material Structures

open access: yesAdvanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...

Implementing multidomain non‐pharmaceutical interventions for preventing cognitive decline in community‐dwelling older adults in China: An embedded mixed‐methods implementation study of determinants and strategies

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION The WW‐FINGERS network has demonstrated the efficacy of multidomain non‐pharmaceutical interventions (NPIs) but left their real‐world implementation largely unexplored, prompting this study in Changxing County to identify key determinants and develop actionable strategies for community‐based delivery.
