Abstract The energy and momentum balance of an abyssal overflow across a major sill in the Samoan Passage is estimated from two highly resolved towed sections, set 16 months apart, results two-dimensional numerical simulation. Driven by density anomaly sill, flow relatively steady. system gains divergence horizontal pressure work flux available potential . Approximately half these are transferr...

Keith Sill is a senior economist in the Research Department of the Philadelphia Fed. Our economy has become increasingly global. We import and export more than ever before. Yet, three facts about international financial transactions, when taken together, pose a puzzle. First, financial capital moves freely across country borders, at least in the case of the developed countries. Returns on simil...

The origin of horizontal magma-filled sills is disputed, particularly for extensional settings where the opening vertical dikes predicted mode magma intrusion. We simulate long-term extension followed by short-term dike in a two-dimensional viscoelastic medium representing plate spreading center. show that extensionally stressed lithosphere can reduce sublithospheric stresses enough sill given ...

Given the shortcomings of current methods to shorten the cutaneous upper lip, the senior authors modified the traditional subnasal lip lift with endonasal flaps, performing 311 such lifts over a 15-year period. Ideal surgical candidates are adults with tall philtra, negligible dental show, and no maxillary abnormalities. Benefits of the procedure include improved scar appearance and pout, absen...

Conservation of cultural heritage is an area where novel scientific techniques are having enormous impact. Given the value and uniqueness of art pieces, non-invasive diagnostic methods are highly appreciated by conservators. Terahertz radiation has shown enormous potential as non-contact probe that can be used for the three-dimensional reconstruction of internal structure of stone-made objects....
