Nearly half of Greenland's mass loss occurs through iceberg calving, but the physical mechanisms operating during calving are poorly known and in situ observations are sparse. We show that calving at Greenland's Helheim Glacier causes a minutes-long reversal of the glacier's horizontal flow and a downward deflection of its terminus. The reverse motion… (More)
Progress in the excitation of `dark-modes' in plasmonic structures is reported. The interaction of vector beams possessing a spatially inhomogeneous polarization profile with plasmonic nanostructures provides an avenue to probe these resonances.
Impressions of footwear are usually found in crime scenes. the standard and wide variability of those impressions makes their analysis is extremely tough. This analysis can develop new process ways to help the rhetorical footwear examiner within the U.S. during this analysis work involves developing a info of representative footwear print pictures in order… (More)
