BACKGROUND A rise or fall of cardiac troponin is a prerequisite for the diagnosis of acute myocardial infarction. Defining significant changes requires knowledge of both biological and analytical variation. The short-term biological variation of cardiac troponin in healthy individuals is 3%-48%. However, healthy individuals may not be representative for patients in whom cardiac troponin measure...
Aim Precipitation controls the production of semi-arid plants through various mechanisms that operate at a range of time-scales. Short-term variation in precipitation affects vegetation through adjustments in plant physiology and leaf phenology, whereas long-term effects are mediated by plant establishment and mortality, community composition and disturbance regimes. Our goal is to use remote s...
We study the joint dynamics of bond yields and macroeconomic variables in a New-Keynesian small open economy model complemented with a no-arbitrage term structure model. With Canadian data, we are able to study the impact of domestic and foreign (US) shocks on the yield curve. The unconditional variance decomposition of the yield level show that the movement of expected short rates is mainly dr...
