Using computational fluid dynamics and field experiments to improve vehicle-based wind measurements for environmental monitoring [PDF]

open access: yesAtmospheric Measurement Techniques, 2020
Vehicle-based measurements of wind speed and direction are presently used for a range of applications, including gas plume detection. Many applications use mobile wind measurements without knowledge of the limitations and accuracy of the mobile ...

Explaining CO2 fluctuations observed in snowpacks [PDF]

open access: yesBiogeosciences, 2018
Winter soil carbon dioxide (CO2) respiration is a significant and understudied component of the global carbon (C) cycle. Winter soil CO2 fluxes can be surprisingly variable, owing to physical factors such as snowpack properties and wind.

Risk [PDF]

open access: yesAmerican Journal of Epidemiology, 2015
The epidemiologist primarily studies transitions between states of health and disease. The purpose of the present article is to define a foundational parameter for such studies, namely risk. We begin simply and build to the setting in which there is more than 1 event type (i.e., competing risks or competing events), as well as more than 1 treatment or ...

Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight

open access: yeseLife, 2021
From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions.

Risk‐of‐bias VISualization (robvis): An R package and Shiny web app for visualizing risk‐of‐bias assessments

open access: yesResearch Synthesis Methods, 2020
Despite a major increase in the range and number of software offerings now available to help researchers produce evidence syntheses, there is currently no generic tool for producing figures to display and explore the risk‐of‐bias assessments that ...

Ultra-short heart rate variability and Poincaré plots

open access: yesParadigmPlus, 2021
The short-term heart rate variability records of 5 minutes are currently considered very extensive compared to other indicators of health and well-being of people, such as body weight, blood glucose, blood pressure, etc.
