Machine Learning‐Assisted Design and Performance Prediction of a Compact Dual‐Band Polarization‐Insensitive THz Metamaterial Absorber for Skin‐Cancer‐Related Refractive‐Index Sensing

Advanced Electronic Materials, EarlyView.
A compact QASRR‐based THz metamaterial absorber enables polarization‐insensitive dual‐band absorption and skin‐cancer‐related refractive‐index sensing through measurable resonance shifts. Field, surface‐current, and circuit analyses clarify the dual‐resonance mechanism, while StackNet‐assisted prediction accurately estimates the simulated absorption ...

Integrating Automated Electrochemistry and High‐Throughput Characterization with Machine Learning to Explore Si─Ge─Sn Thin‐Film Lithium Battery Anodes

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
A closed‐loop, data‐driven approach facilitates the exploration of high‐performance Si─Ge─Sn alloys as promising fast‐charging battery anodes. Autonomous electrochemical experimentation using a scanning droplet cell is combined with real‐time optimization to efficiently navigate composition space.

Decay patterns and carbon density of standing dead trees in California mixed conifer forests

Forest Ecology and Management, 2015
Abstract Dead wood plays important structural and biogeochemical roles in forest ecosystem processes. Some aspects of woody debris dynamics have been carefully studied, but the decay patterns and carbon density of standing dead (SD) trees are only weakly characterized.

Decomposition of standing dead trees in the southern Appalachian Mountains

Oecologia, 1982
Decomposition of standing dead trees that were killed by fire was examined for 10 species in the Great Smoky Mountains National Park. The decrease in wood density as fire age increased was used to estimate decomposition rates. Quercus prinus had the fastest decay rate (11% yr-1) while Pinus virginiana had the slowest decay rate (3.6% yr-1) for standing

Interpreting effects of multiple, large-scale disturbances using national forest inventory data: A case study of standing dead trees in east Texas, USA

Forest Ecology and Management, 2019
Understanding the impacts of large-scale disturbances on forest conditions is necessary to support forest management, planning, and policy decision making.

Habitat value of, and social attitudes towards, dead trees in Canberra’s urban forest

Australian Forestry, 2021
Dead trees can occur throughout an urban forest and need to be managed. Standing dead trees that have been made ‘safe’ through regular inspection and the removal of unstable and decaying material are called ‘totem trees’ by Transport Canberra and City ...

Standing Dead Trees: a Conduit for the Atmospheric Flux of Greenhouse Gases from Wetlands?

Wetlands, 2016
Wetlands represent the largest natural source of methane flux to the atmosphere, which can occur across the sediment/water/plant-atmosphere interface. Of these three potential methane sources, the role of vegetation in this flux is the least well understood.

Wood transformation in dead-standing trees in the forest-tundra of Central Siberia

Biology Bulletin, 2009
Changes in the composition of wood organic matter in dead-standing spruce and larch trees depending on the period after their death have been studied in the north of Central Siberia. The period after tree death has been estimated by means of cross-dating.
