Uncertainty-aware Bayesian machine learning modelling of land cover classification [PDF]

open access: yesarXiv
Land cover classification involves the production of land cover maps, which determine the type of land through remote sensing imagery. Over recent years, such classification is being performed by machine learning classification models, which can give highly accurate predictions on land cover per pixel using large quantities of input training data ...

Sustainable Pathways for the Synthesis of Calcium Sulfate Hemihydrate

open access: yesAngewandte Chemie International Edition, EarlyView.
Calcium sulfate hemihydrate (bassanite) plays a key role in construction as a hydraulic binder. Due to its instability in water, industrial production primarily relies on thermal dehydration of gypsum. This review examines alternative, potentially more sustainable methods for the synthesis of bassanite, including gypsum conversion at lower temperatures

Plastics of the Future? Interdisciplinary Review on Biobased and Biodegradable Polymers: Progress in Chemistry, Societal Views, and Environmental Implications

open access: yesAngewandte Chemie International Edition, Accepted Article.
Global demand to reduce polymer waste and microplastics pollution has increased in recent years, prompting further research, development, and wider use of biodegradable and biobased polymers (BBPs). BBPs have emerged as promising alternatives to conventional plastics, with the potential to mitigate the environmental burdens of persistent plastic waste.

Distribution models calibrated with independent field data predict two million ancient and veteran trees in England

open access: yesEcological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract Large, citizen‐science species databases are powerful resources for predictive species distribution modeling (SDM), yet they are often subject to sampling bias. Many methods have been proposed to correct for this, but there exists little consensus as to which is most effective, not least because the true value of model predictions is hard to ...

Volatile Elements Characterized by MarSCoDe in Materials at Zhurong Landing Site

open access: yesThe Astronomical Journal
The study of volatile elements on the Martian surface is a critical way to explore the geological evolution history of Mars. Volatile elements such as hydrogen (H), sulfur (S), and chlorine (Cl) on the Martian surface act as proxies for the potential ...

Functional diversity of farmland bees across rural–urban landscapes in a tropical megacity

open access: yesEcological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract Urbanization poses a major threat to biodiversity and food security, as expanding cities, especially in the Global South, increasingly compete with natural and agricultural lands. However, the impact of urban expansion on agricultural biodiversity in tropical regions is overlooked.
