Biotic and physical drivers of fire in northwestern Patagonia

open access: yesFire Ecology
Abstract Background Understanding the drivers of fire is frequently challenging because some of them interact and influence each other. In particular, vegetation type is a strong control of fire activity, but at the same time it responds to physical and human factors that also affect fire, so ...

Near‐Field Nanoimaging of Programmable Phase Transitions in Ga+‐Irradiated VO2

open access: yesAdvanced Optical Materials, EarlyView.
Focused Ga+ ion irradiation locally reprograms the insulator‐to‐metal transition in VO2 thin films. Infrared and terahertz near‐field nanoimaging reveals that low irradiation doses localize the resistive‐switching filament within the defect region, while high doses suppress switching there and redirect the filament into pristine VO2.

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

open access: yesAdvanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Boreal Forest Fire Causes Daytime Surface Warming During Summer to Exceed Surface Cooling During Winter in North America

open access: yesAGU Advances
Boreal wildfires modify surface climates affecting plant physiology, permafrost thaw, and carbon fluxes. Post‐fire temperatures vary over decades because of successional vegetation changes. Yet, the underlying biophysical drivers remain uncertain.

Drivers of wildland fire behaviour variation across the Earth

open access: yes, 2018
Fire behaviour characteristics define the impacts on society and the environment. While wildland fire science has expanded to include the analysis of fire activity and effects across the globe, an understanding of global fire behaviour patterns and its ...
