Using Shapley additive explanations to interpret extreme gradient boosting predictions of grassland degradation in Xilingol, China [PDF]

Geoscientific Model Development, 2021
Machine learning (ML) and data-driven approaches are increasingly used in many research areas. Extreme gradient boosting (XGBoost) is a tree boosting method that has evolved into a state-of-the-art approach for many ML challenges.

Non-Contact Automatic Vital Signs Monitoring of Infants in a Neonatal Intensive Care Unit Based on Neural Networks

Journal of Imaging, 2021
Infants with fragile skin are patients who would benefit from non-contact vital sign monitoring due to the avoidance of potentially harmful adhesive electrodes and cables. Non-contact vital signs monitoring has been studied in clinical settings in recent

Influence of Weather, Soil Variability, and Vegetation on Seasonal Ground Movement: A Field Study

Geotechnics, 2023
Expansive soils change volume due to changes in moisture content, which results in ground movement. Lightweight shallow-depth structures such as pavements, residential footings, and pipelines can suffer distress as they face additional stresses from the ...

High resolution remote sensing for reducing uncertainties in urban forest carbon offset life cycle assessments

Carbon Balance and Management, 2017
Background Urban forests reduce greenhouse gas emissions by storing and sequestering considerable amounts of carbon. However, few studies have considered the local scale of urban forests to effectively evaluate their potential long-term carbon offset ...

A high solids field-to-fuel research pipeline to identify interactions between feedstocks and biofuel production

Biotechnology for Biofuels, 2021
Background Environmental factors, such as weather extremes, have the potential to cause adverse effects on plant biomass quality and quantity. Beyond adversely affecting feedstock yield and composition, which have been extensively studied, environmental ...

Spatiotemporal trends of urban-induced land use and land cover change and implications on catchment surface imperviousness

Applied Water Science, 2023
Urbanization, changes in land use and land cover (LULC), and an increase in population collectively have significant impacts on urban catchments. However, a vast majority of LULC studies have been conducted using readily available satellite imagery ...

Computational modelling and experimental characterisation of heterogeneous materials [PDF]

, 2009
Heterogeneous materials can exhibit behaviour under load that cannot be described by classical continuum elasticity. Beams in bending can show a relative stiffening as the beam depth tends to zero, a size effect.

Nitrogen and phosphorus limitation of phytoplankton growth in New Zealand lakes: Implications for eutrophication control [PDF]

, 2010
We examine macronutrient limitation in New Zealand (NZ) lakes where, contrary to the phosphorus (P) only control paradigm, nitrogen (N) control is widely adopted to alleviate eutrophication.
