Upper altitude limit for Rayleigh lidar

It has long been assumed that Rayleigh lidar can be used to measure atmospheric temperature profiles up to about 90 or 100 km and that above this region the technique becomes invalid due to changes in atmospheric composition which affect basic assumptions on which Rayleigh lidar is based. Modern powerful Rayleigh lidars are able to measure backscatter from well above 100 km requiring a closer e...

The Stellar Upper Mass Limit Preserved

This article is based on data gathered with three facilities: the NASA/ESA Hubble Space Telescope (HST), the 6.5 m Magellan Telescopes at Las Campanas Observatory (LCO), and the 2.15-m J. Sahade telescope at Complejo Astronómico El Leoncito (CASLEO). The HST observations are associated with GO program 10602. HST is controlled from the Space Telescope Science Institute, which is operated by the ...

An upper limit for macromolecular crowding effects

BACKGROUND Solutions containing high macromolecule concentrations are predicted to affect a number of protein properties compared to those properties in dilute solution. In cells, these macromolecular crowders have a large range of sizes and can occupy 30% or more of the available volume. We chose to study the stability and ps-ns internal dynamics of a globular protein whose radius is ~2 nm whe...
