We set new limits on the mass of the Milky Way, making use of the latest kinematic information for Galactic satellites and halo objects. Our sample consists of 11 satellite galaxies, 137 globular clusters, and 413 field horizontal-branch (FHB) stars up to distances of 10 kpc from the Sun. Roughly half of the objects in this sample have measured proper motions, permitting the use of their full s...

Sequential satellite microwave images of tropical cyclones readily lend themselves to morphing applications, which allow for a straightforward visualization of the storms' structural trends. P olar and other low-Earth-orbiting (LEO) satellites provide critical data for use in weather analysis and forecasting. However, the temporal sampling issue leads to the common problem of interpreting seque...

Measuring greenhouse gas (GHG) profiles with global coverage and high accuracy and vertical resolution in the upper troposphere and lower stratosphere (UTLS) is key for improved monitoring of GHG concentrations in the free atmosphere. In this respect a new satellite mission concept adding an infrared-laser part to the already well studied microwave occultation technique exploits the joint propa...

Fifty years have passed since a visit to the United States set in train the building in Britain of the world’s first business computer. The computer was built by J. Lyons & Co., then Britain’s leading caterer with a household name for its teashops, its packeted tea and its cakes and ice cream. The system was given the name LEO, Lyons Electronic Office, and on it was run the world’s first regula...

In the above article the reference to Hering, E. (1878/1964) should be (1920/1964). Leo M. Hurvich has kindly pointed out to the author that ‘Outlines of a Theory of the Light Sense’ (Cambridge, Harvard University Press, 1964, translated by Leo M. Hurvich and Dorothea Jameson), is based on Ewald Hering’s ‘Grundzuge der Lehre vom Lichtsinn’ (Berlin, Springer, 1920), and not, as has often been as...

Here we describe the design and strength of a new synthetic late-early optimized (LEO) vaccinia virus (VACV) promoter used as a transcriptional regulator of GFP expression during modified vaccinia Ankara infection. In contrast to the described synthetic VACV promoter (pS), LEO induced significantly higher levels of GFP expression in vitro within the first hour after infection, which correlated ...

Direct comparison of high-resolution X-ray spectra of the active dMe star AD Leo, observed three times with Chandra, shows variability of key density-sensitive lines, possibly due to flaring activity. In particular, a significant long-duration enhancement of the coronal density is indicated by the Ne IX and Si XIII He-like triplets, and possibly also by density-sensitive Fe XXI line ratios. Sub...
