Near Surface Geophysics, EarlyView.Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.

How can children and young people have a voice in urban treescapes?
People and Nature, EarlyView.Abstract Scientific understanding of climate change has, to date, failed to result in sufficient action. This paper proposes that a deficit model of top‐down learning and dissemination in relation to public engagement with science may be part of the problem, particularly when considering the attitudes, values and empowerment of children and young ...

Thinking with trees: Responding to sympoietic plant relations through visual art
PLANTS, PEOPLE, PLANET, EarlyView.Amid escalating climate crises, this paper explores how we might rethink our relationship with the natural world, particularly with plants and trees, through the perspectives of visual art. This paper reveals how art invites us to see trees and other plant life not as passive background scenery, but as living beings with their own forms of experience ...

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

River Research and Applications, EarlyView.ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...
