Key predisposing factors and susceptibility assessment of landslides along the Yunnan–Tibet traffic corridor, Tibetan plateau: Comparison with the LR, RF, NB, and MLP techniques

Frontiers in Earth Science, 2023
The Yunnan–Tibet traffic corridor runs through the Three Rivers Region, southeastern Tibetan Plateau, which is characterized by high-relief topography and active tectonics, with favourable conditions for landslides.

Important Variables in Granulocyte Chemiluminescence

Experimental Biology and Medicine, 1979
SummaryA CL system consisting of canine granulocytes stimulated with opsonized zymosan was used to examine factors which lead to variability in light production. Variability of CL response was associated with granulocyte aggregation. Granulocyte aggregation was reduced by: (i) reducing centrifu-gation and mixing forces used to prepare cell suspensions,

Vegetation Fuel Mapping at Regional Scale Using Sentinel-1, Sentinel-2, and DEM Derivatives—The Case of the Region of East Macedonia and Thrace, Greece

Remote Sensing, 2023
The sustainability of Mediterranean ecosystems, even if previously shaped by fire, is threatened by the diverse changes observed in the wildfire regime, in addition to the threat to human security and infrastructure losses. During the two previous years,

Variable Importance Clouds: A Way to Explore Variable Importance for the Set of Good Models

CoRR, 2019
Variable importance is central to scientific studies, including the social sciences and causal inference, healthcare, and other domains. However, current notions of variable importance are often tied to a specific predictive model. This is problematic: what if there were multiple well-performing predictive models, and a specific variable is important ...

Evaluation of Four Supervised Learning Methods for Benthic Habitat Mapping Using Backscatter from Multi-Beam Sonar

Remote Sensing, 2012
An understanding of the distribution and extent of marine habitats is essential for the implementation of ecosystem-based management strategies. Historically this had been difficult in marine environments until the advancement of acoustic sensors.
