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 ...

Sovereign Risk and Financial Risk [PDF]

open access: yesSSRN Electronic Journal, 2021
This paper examines the relationship between sovereign bond spreads, local economic activity, and global financial risk. We use secondary-market prices of dollar-denominated sovereign securities to construct yield spreads between sovereign bond yields and yields on the appropriately defined default risk-free securities, constructed using zero-coupon U ...

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.

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.

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.

High-pass filter characteristics of the baroreflex--a comparison of frequency domain and pharmacological methods. [PDF]

open access: yesPLoS ONE, 2013
Pharmacological methods to assess baroreflex sensitivity evoke supra-physiological blood pressure changes whereas computational methods use spontaneous fluctuations of blood pressure.

RoB 2: a revised tool for assessing risk of bias in randomised trials

open access: yesBritish medical journal, 2019
Assessment of risk of bias is regarded as an essential component of a systematic review on the effects of an intervention. The most commonly used tool for randomised trials is the Cochrane risk-of-bias tool. We updated the tool to respond to developments

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 ...

Risks and Risks [PDF]

open access: yesScience, 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 ...
