This paper revisits the Lucas paradox by quantifying empirically the relevance of a specific set of policies — restrictions on international capital flows — in shaping the patterns of capital movements at various stages of economic development. The determinants of the direction of capital flows, and their relation to economic development, constitute an important topic in open economy macroecono...

Noninvasive cardiac imaging, either at rest or during stress, has been for many years an integral part of evahrating and managing patients with suspected or known coronary artery disease. In the present era, when appropriate use of resources is under heavy scrutiny, the use of noninvasive imaging modalities can be expected to increase, further serving as effective gatekeepers for triaging and d...

Contact detection algorithm is a critical constituent of discontinuous calculation method, the accuracy contact directly affects simulation results. Algorithms for between irregular blocks are difficult to achieve because complexity geometry and diversity types. A half-space based proposed, it can accurately identify relationship convex polygonal polyhedral blocks. The proposed approach impleme...
