ON ROTATIONAL INVARIANCE OF HIGHER-ORDER MOMENTS OF REGULAR POLYHEDRA

open access: yesFacta Universitatis. Series: Architecture and Civil Engineering
This paper covers aspects of establishing a relationship between the highest-order rotation-invariant moments of inertia and the order of symmetry of Platonic polyhedra. Moments of inertia about arbitrary, but centroidal axes are considered.

Responses of Water Use Efficiency to Drought in Southwest China

open access: yesRemote Sensing, 2020
Water use efficiency (WUE) measures the tradeoff between carbon uptake and water consumption in terrestrial ecosystems. It remains unclear how the responses of WUE to drought vary with drought severity.

Assessment of MISR and MODIS cloud top heights through inter-comparison with a back-scattering lidar at SIRTA [PDF]

open access: yes, 2004
One year of back-scattering lidar cloud boundaries and optical depth were analysed for coincident inter-comparison with the latest processed versions of the NASA-TERRA MISR stereo and MODIS CO2-slicing operational cloud top heights. Optically thin clouds

Estimating the fractional cover of growth forms and bare surface in savannas. A multi-resolution approach based on regression tree ensembles [PDF]

open access: yes, 2013
Evaluations of existing land cover maps have revealed that high landscape heterogeneity and small patch sizes are a major reason for misclassification.

Stabilising Repair in Psychological Science

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT Psychological science has responded to the WEIRD critique through a broad agenda of inclusion, expanding the diversity of research participants, international collaborations and systems of scholarly recognition. While these reforms have generated important gains, concerns about epistemic inequality persist.

Complexity in the Wake of Artificial Intelligence

open access: yesComplexity
This study aims to evaluate quantitatively (albeit in arbitrary units) the evolution of complexity of the human system since the domestication of fire. This is made possible by studying the timing of the 14 most important milestones—breaks in historical ...

Monitoring of agricultural drought using remote sensing data in the Sebou watershed, Morocco [PDF]

open access: yesE3S Web of Conferences
Drought is a climatic phenomenon that can adversely affect the environment and human activities. Currently, agricultural drought has become a concern in countries where agriculture largely depends on rainfall and is highly vulnerable to climatic ...

Automated Plantation Mapping in Southeast Asia Using MODIS Data and Imperfect Visual Annotations

open access: yesRemote Sensing, 2020
Expansion of large-scale tree plantations for commodity crop and timber production is a leading cause of tropical deforestation. While automated detection of plantations across large spatial scales and with high temporal resolution is critical to inform ...

Creation of a Landslide Susceptibility Map Using Short‐Term Data From the July 2018 Heavy Rainfall in Southern Hiroshima Prefecture

open access: yesGeological Journal, EarlyView.
This work advances landslide susceptibility mapping by incorporating short‐term trigger data with landscape susceptibility mapping. We also examine the importance of downsampling, watershed delineation and geospatial correlations in evaluating outcomes.
