A Slow Merger History of Field Galaxies since Z ∼

Using deep infrared observations conducted with the CISCO imager on the Subaru Telescope, we investigate the field-corrected pair fraction and the implied merger rate of galaxies in redshift survey fields with Hubble Space Telescope imaging. In the redshift interval, 0.5 < z < 1.5, the fraction of infrared-selected pairs increases only modestly with redshift to 7% ± 6% at z ∼ 1. This is nearly ...

A History of Cerebrovascular Disease since the Renaissance

In the last three decades, there have been tremendous advances in technology and scientific knowledge that have revolutionized stroke prevention, diagnosis, and treatment. Noninvasive, painless, and safe imaging techniques now enable the clinician to pinpoint the size and location of brain lesions that in the not too distant past could be suspected but not easily or safely confirmed. Only 40 ye...

Shear history independence in colloidal aggregation.

Stimulated by experiments, we have carried out detailed simulations of aggregation in the presence of shear in a model colloidal system with a short-range attractive potential. For weak shear rates, we find that the shear enhanced the aggregation and that the long-time state of the system is independent of the shear history. For strong shear rates, precipitous fragmentation occurred after the s...
