Distributed Formation Control for Heterogeneous Robot Systems Based on Competitive Mechanism

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT This paper presents an adaptive formation control method for a heterogeneous robot swarm, utilising a multilevel formation task tree to model various types of formation tasks and a single‐state distributed k‐winner‐take‐all (S‐DKWTA) algorithm to address the MRTA problem.

Addressing ecological challenges from a quantum computing perspective

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract With increased access to data and the advent of computers, the use of statistical tools and numerical simulations is becoming commonplace for ecologists. These approaches help improve our understanding of ecological phenomena and their underlying mechanisms in increasingly complex environments.

DImodelsMulti: An R package for fitting Diversity‐Interactions models to repeated measures or multivariate data

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Diversity‐Interactions (DI) modelling is a regression‐based approach used for modelling the biodiversity and ecosystem function (BEF) relationship. This methodology assesses the effects of manipulating (initial) species richness, composition (species identities) and species proportions on ecosystem function responses measured at a later point ...

Measuring the time‐varying market efficiency in the prewar and wartime Japanese stock market, 1924–1943

open access: yesAsia‐Pacific Economic History Review, Volume 65, Issue 1, Page 131-159, March 2025.
Abstract This study examines the adaptive market hypothesis in the prewar and wartime Japanese stock market using a new market capitalization‐weighted price index. First, we find that the degree of market efficiency varies over time and with major historical events. This implies that the hypothesis is supported in this market.
