Ecological Integrity Evaluation Based on Landscape Index

2012 2nd International Conference on Remote Sensing, Environment and Transportation Engineering, 2012
The impacts of land use on ecosystem have received high attention in global environmental change. Different land use patterns and intensities play significant impact on ecological integrity, which can be directly reflected on ecosystem composition and structure.

Structure−Activity Landscape Index:  Identifying and Quantifying Activity Cliffs

Journal of Chemical Information and Modeling, 2008
A new method for analyzing a structure-activity relationship is proposed. By use of a simple quantitative index, one can readily identify "structure-activity cliffs": pairs of molecules which are most similar but have the largest change in activity. We show how this provides a graphical representation of the entire SAR, in a way that allows the salient

Geomorphodiversity index: Quantifying the diversity of landforms and physical landscape

Science of The Total Environment, 2017
The physical landscape is the mosaic resulting from a wide spectrum of environmental components. The landforms define the variety, or diversity, of the geomorphological component: the geomorphodiversity. Landforms are usually represented in thematic maps where the scale and the graphic solutions are widely heterogeneous. Since geomorphological maps are

LANDSCAPE DEVELOPMENT INTENSITY INDEX

Environmental Monitoring and Assessment, 2005
The condition of landscapes and the ecological communities within them is strongly related to levels of human activity. Human-dominated land uses and especially the intensity of the uses can affect adjacent ecological communities through direct, secondary, and cumulative impacts.

The epidemiological landscape of thyroid cancer worldwide: GLOBOCAN estimates for incidence and mortality rates in 2020.

The Lancet Diabetes and Endocrinology, 2022
BACKGROUND Thyroid cancer incidence rates have increased in many countries and settings; however, mortality rates have remained stable at lower rates. This epidemiological pattern has been largely attributed to an overdiagnosis effect.
