On the Complexity of Signed Roman Domination

open access: yesCoRR
Given a graph $G = (V, E)$, a signed Roman dominating function is a function $f: V \rightarrow \{-1, 1, 2\}$ such that for every vertex $u \in V$: $\sum_{v \in N[u]} f(v) \geq 1$ and for every vertex $u \in V$ with $f(u) = -1$, there exists a vertex $v \in N(u)$ with $f(v) = 2$.

Combined storytelling and mapping approaches for increasing community engagement with woodland creation and expansion projects

open access: yesPeople and Nature, EarlyView.
Abstract Forests and woodlands are important for biodiversity, climate change mitigation and the provision of services including recreation, timber and non‐timber forest products. Land use policies currently aim to increase forest cover while also maximising the benefits of forests for people and improving community engagement with the process of ...

The potential effect of megafaunal extinctions on modern conservation of horse chestnut Aesculus hippocastanum

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...

Modulation of North Atlantic atmospheric rivers by the Gulf Stream

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Gulf Stream ocean variability plays a key role in modulating atmospheric river (AR) activity over the North Atlantic during winter and spring at monthly time‐scales. Increased ocean heat transport and mesoscale activity in the Gulf Stream are linked to northward shifts in ARs, while stronger surface heat fluxes drive ARs southward.

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.
