Spatial Variability in COVID-19 Mortality [PDF]

open access: yesInternational Journal of Environmental Research and Public Health, 2021
COVID-19 emerged as a global pandemic in the spring of 2020. Since that time, the disease has resulted in approximately 150 million cases and 3 million deaths worldwide. However, there is significant spatial variation in the rate of mortality from COVID-19.

Spatial variability of apparent electrical conductivity and soil properties in a coffee production field [PDF]

open access: yesEngenharia Agrícola, 2014
Precision agriculture based on the physical and chemical properties of soil requires dense sampling to determine the spatial variability of these properties. This dense sampling is often expensive and time-consuming.

Isotopic niche variability in macroconsumers of the East Scotia Ridge (Southern Ocean) hydrothermal vents: What more can we learn from an ellipse? [PDF]

open access: yes, 2016
Aspects of between-individual trophic niche width can be explored through the isotopic niche concept. In many cases isotopic variability can be influenced by the scale of sampling and biological characteristics including body size or sex.

A three dimensional finite element model of wind effects upon higher harmonics of the internal tide. [PDF]

open access: yes, 2007
A non-linear three dimensional unstructured grid model of the M2 tide in the shelf edge area off the west coast of Scotland is used to examine the spatial distribution of the M2 internal tide and its higher harmonics in the region.

Spatial variability of low frequency brain signal differentiates brain states.

open access: yesPLoS ONE, 2020
Temporal variability of the neural signal has been demonstrated to be closely related to healthy brain function. Meanwhile, the evolving brain functions are supported by dynamic relationships among brain regions.

Influence of rock mass spatial variability on probability of tunnel roof wedge failure

open access: yesRock and Soil Mechanics, 2021
In tunnel design and construction, the stability evaluation of tunnel roof wedge usually adopts traditional deterministic analysis methods, which cannot appropriately reflect the spatial variability of rock mass.

Variability of climate, water and nitrogen status and its influence on vine phenology and grape composition inside a small winegrowing estate

open access: yesE3S Web of Conferences, 2018
Climate is a major terroir factor in viticulture. In winegrowing regions, climate is studied at an increasingly refined scale. Results from the Life ADVICLIM project show substantial spatial variability of temperatures inside the region of Saint-Emilion,
