Detecting social‐ecological fit in Natura 2000 governance and management: Evidence from LIFE projects focused on forest protected habitat types

open access: yesPeople and Nature, EarlyView.
Abstract Protected areas represent complex social‐ecological systems that require governance and management approaches that valorise and enhance positive relationships between people and nature. This study analyses the alignment between social and ecological systems to detect the social‐ecological fit of projects focused on biodiversity conservation ...

Relations between ordinary energy and energy of a self-loop graph

open access: yesHeliyon
Let G be a graph on n vertices with vertex set V(G) and let S⊆V(G) with |S|=α. Denote by GS, the graph obtained from G by adding a self-loop at each of the vertices in S.

Generating Compressed Counterfactual Hard Negative Samples for Graph Contrastive Learning

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Graph contrastive learning (GCL) relies on acquiring high‐quality positive and negative samples to learn the structural semantics of the input graph. Previous approaches typically sampled negative samples from the same training batch or an irrelevant external graph.

Forced Multi-Agent Bipartite Consensus Control: Application to Quadrotor Formation Flying

open access: yesIEEE Access
This work investigates the multi-agent bipartite consensus problem in the presence of switching antagonistic interactions. For leaderless multi-agent systems communicating over a structurally balanced sign graph with switching antagonistic interactions ...

On the irregularity of bipartite graphs

open access: yesDiscrete Mathematics, 2007
Let \(G=(V,E)\) be a finite simple graph. For \(u\in V\), let \(d(u)\) denote the valence of \(u\). For any edge \(e=uv\in E\), the imbalance of \(e\) is \(| d(u)-d(v)| \). The irregularity of \(G\), denoted \(\text{{irr}}(G)\), is the sum of the imbalances of the edges of \(G\). These notions are due to \textit{M. O. Albertson} [Ars Comb. 46, 219--225

Boosting Embodied Visual Localisation Through Multi‐Granular Semantics and Multi‐Robot Consensus

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Achieving high accuracy and synergy remains extremely difficult for multi‐robot embodied visual localisation, which suffers from persistent real‐world challenges such as viewpoint ambiguity, appearance variation and dynamic occlusion. Conventional optimisation‐based methods often lead to incorrect feature matching without domain adaptation ...

Hidden Losses: Assessing the Risk of Coextinction Among Ectoparasitic Flies and Their Bat Host Species in Brazil

open access: yesAnimal Conservation, EarlyView.
The potential impact of bat species extinction on the number of their ectoparasitic fly species, based on interaction data for Brazil. As bat host species are removed over time, more connected species (green) would experience steeper declines and lead to greater ectoparasite losses when compared to a random extinction model (gray).
