Topological search and gradient descent boosted Runge–Kutta optimiser with application to engineering design and feature selection

open access: yesCAAI Transactions on Intelligence Technology, Volume 10, Issue 2, Page 557-614, April 2025.
Abstract The Runge–Kutta optimiser (RUN) algorithm, renowned for its powerful optimisation capabilities, faces challenges in dealing with increasing complexity in real‐world problems. Specifically, it shows deficiencies in terms of limited local exploration capabilities and less precise solutions.

Effect of different instrumental techniques and clinical experience on shade matching

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose Many factors can affect the aesthetics of dental restorations, including the instrumental techniques used in shade matching, and can lead to clinical failure. The aim of this study was to investigate the effectiveness of using the cross‐polarization digital photograph technique and intraoral scanners for shade matching, and also ...

Co‐creating the future through design thinking: Deconstructing the consumer co‐creation process

open access: yesJournal of Product Innovation Management, Volume 42, Issue 3, Page 528-556, May 2025.
Abstract Consumer co‐creation, an approach in which consumers and organizations jointly innovate, can yield valuable knowledge about consumers' needs and how to satisfy these needs. Yet, innovating with consumers is challenging due to their varying levels of commitment, skills, and motivations.

Frobenius Manifolds And Virasoro Constraints

open access: yes, 1999
For an arbitrary Frobenius manifold a system of Virasoro constraints is constructed. In the semisimple case these constraints are proved to hold true in the genus one approximation. Particularly, the genus $\leq 1$ Virasoro conjecture of T.Eguchi, K.Hori,

Failure of the Hasse principle on general K3 surfaces [PDF]

open access: yesarXiv, 2011
We show that transcendental elements of the Brauer group of an algebraic surface can obstruct the Hasse principle. We construct a general K3 surface X of degree 2 over Q, together with a two-torsion Brauer class A that is unramified at every finite prime, but ramifies at real points of X.

Using accelerometry tags to quantify gray whale foraging behavior

open access: yesMarine Mammal Science, Volume 41, Issue 2, April 2025.
Abstract High‐resolution tri‐axial accelerometry biologging tags have quantitatively described behaviors in baleen whale species that forage using lunges and continuous ram filtration. However, detailed quantitative descriptions of foraging behaviors do not exist for gray whales, a unique baleen whale species that primarily uses benthic suction feeding

Fair Simulation for Nondeterministic and Probabilistic Buechi Automata: a Coalgebraic Perspective

open access: yes, 2017
Notions of simulation, among other uses, provide a computationally tractable and sound (but not necessarily complete) proof method for language inclusion.

Assisted return programmes across Europe – Mapping an increasingly obscure landscape

open access: yesInternational Migration, Volume 63, Issue 3, June 2025.
Abstract Amidst an increasing popularity of Assisted Return (AR) programmes amongst European states, on the one hand, and criticism pertaining to their voluntary and humanitarian nature, on the other hand, this paper maps AR programmes across Europe.

Relations between connected and self-avoiding walks in a digraph [PDF]

open access: yes, 2015
Walks in a directed graph can be given a partially ordered structure that extends to possibly unconnected objects, called hikes. Studying the incidence algebra on this poset reveals unsuspected relations between walks and self-avoiding hikes.

Random Walk‐Based GOOSE Algorithm for Solving Engineering Structural Design Problems

open access: yesEngineering Reports, Volume 7, Issue 5, May 2025.
This paper presents a novel Random Walk‐premised GOOSE (IGOOSE) search algorithm for solving engineering structural design problems. In the IGOOSE algorithm, each solution represented as a potential solution to an optimization search problem behaves akin to a random walker navigating through a solution space.
