In this paper, we study the electromagnetic scattering from a two dimensional large rectangular open cavity embedded in an infinite ground plane, which is modelled by Helmholtz equations. By introducing nonlocal transparent boundary conditions , the problem in the open cavity is reduced to a bounded domain problem. A hypersingular integral operator and a(More)
Although deformation processes in submicron-sized metallic crystals are well documented, the direct observation of deformation mechanisms in crystals with dimensions below the sub-10-nm range is currently lacking. Here, through in situ high-resolution transmission electron microscopy (HRTEM) observations, we show that (1) in sharp contrast to what happens(More)
In corporate spin-offs, spun-off units pursue two major objectives: separating and restructuring their business for independent operation; and retaining business continuity and minimizing operational disruptions. In trying to balance the conflicting demands of these objectives, spun-off units often turn to " transitional IT services " provided by their(More)
Prior research has paid very little attention, if at all, to the risks and costs entailed in IT disintegration processes. In this study, we begin addressing this gap by studying how IT disintegration challenges posed by corporate divestitures affect the regulatory compliance risks and costs of divesting firms in the context of the Sarbanes-Oxley Act of 2002(More)
