ABSTRACT Background The effects of phosphodiesterase 5 (PDE5) inhibitors on the incidence of long‐term outcomes in patients with cardiovascular disease are not well understood. Objective: We studied the association between PDE5 inhibitor therapy and the incidence of adverse cardiovascular major adverse cardiovascular events (MACE) in patients ...

Long and short arc altitude determination for GEOS-C [PDF]
The accuracy with which the GEOS-C altitude may be estimated over long (7 day) and short (40 minute) orbital arcs is investigated. Over the long are excellent agreement was attained between a simulation of the orbit determination process and a covariance

A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

Results from flight and simulator studies of a Mach 3 cruise longitudinal autopilot [PDF]
At Mach numbers of approximately 3.0 and altitudes greater than 21,300 meters, the original altitude and Mach hold modes of the YF-12 autopilot produced aircraft excursions that were erratic or divergent, or both.

Five large Alpine cave systems on the Dachstein (Austria) were investigated and 35 sediment profiles or outcrops between 860 m a.s.l. and 1945 m a.s.l. were analysed. An altitude‐dependent overall stratigraphy is established and depositional conditions and palaeo‐environments are reconstructed.
