The sensitivity of a source apportionment model to mobile source profiles was examined to determine the impact of using non-local mobile source profiles in chemical mass balance (CMB) models. Weâ€¦ (More)

For an inequality system defined by a possibly infinite family of proper functions (not necessarily lower semicontinuous), we introduce some new notions of constraint qualifications in terms of theâ€¦ (More)

Neonatal bowel perforation is a potentially lethal disease whose etiology and pathophysiology remain unclear. An aggressive approach with surgical intervention has been favored by some authors;â€¦ (More)

We consider the DC optimization problem (P) inf xâˆˆX {(f1(x) âˆ’ f2(x)) + (g1(Ax) âˆ’ g2(Ax))}, where f1, f2, g1 and g2 are proper convex functions defined on locally convex Hausdorff topological vectorâ€¦ (More)

The Ordos region in the southwestern part of Inner Mongolia experiences frequent PM concentrations in excess of the national PM2.5 air quality standards. In order to determine the key sources ofâ€¦ (More)
