Scattering off the edge of a composite particle or finite-range interaction can precede that its center. An effective theory treatment with pointlike particles and contact interactions must find scattered experimental wave is slightly advanced, in violation causality (the fundamental underlying being causal). In practice, partial-wave other projections multivariate amplitudes exponentially grow...

In complex analysis, the natural domains to study are the pseudoconvex ones. However, the easiest ones to do analysis on are the convex domains. So many results are obtained by looking for convexity. In this talk we will discuss exposing points on boundaries of pseudoconvex domains. This means convexifying the domains. This is recent joint work with Klas Diederich and Erlend F. Wold 11:00 to No...

A regioselective [3 + 2] cycloaddition of benzofuranone type active olefins with allenoates catalyzed by trivalent phosphines has been developed, which provided an easy access to enriched functionalized spirocyclic benzofuranones. The reactions accommodated a number of benzofuranone type electron-deficient olefins and allenoates to give the desired 3-spirocyclopentane benzofuran-2-ones or 2-spi...

Concepts dealing with the subdivision of the human liver into independent vascular and biliary territories are applied routinely in radiological, surgical, and gastroenterological practice. Despite Couinaud's widely used eight-segments scheme, opinions on the issue differ considerably between authors. The aim of this article is to illustrate the scientific basis for understanding and harmonizin...
