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

American 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 ...

Science, 2005 When society makes a decision about some action (to build a dam or approve a new drug, for example), its choice is usually based on a comparison of risks and benefits. If the latter exceed the former, assuming that risks and benefits accrue to the same person or group, the project goes forward ...

Political Risk, Economic Risk, and Financial Risk [PDF]
Financial Analysts Journal, 1996 Given the increasingly global nature of investment portfolios, an understanding of country risk is very important. This article addresses the economic content of five different measures of country risk: four measures from the International Country Risk Guide's political-, financial-, economic-, and composite-risk indexes and one from Institutional ...
