In recent years, non-deterministic clock synchronisation algorithms (NDCSA) have appeared as an attractive alternative to deter-ministic ones. NDCSA ooer a precision that can be made as small as desired. The price to pay is a probability of success that is less than one. We propose an uniform analysis of NDCSA. Our approach strives at decomposing and identifying the factors that aaect the perfo...
In this paper we consider new upscaling and homogenization methods for the pressure equation that are less sensitive to the boundary condition assumptions than many other published methods. We start from the discretized pressure equation and rely on the construction of subproblems with signii-cantly fewer unknowns, describing the behaviour of the solution of the ne-grid problem in suitable subs...
The current work reports an organocatalytic strategy for the asymmetric catalysis of chiral benzofuran-2(3H)-ones bearing 3-position all-carbon quaternary stereocenters. Accordingly, highly enantioselective Michael addition reactions of 3-substituted benzofuran-2(3H)-ones to nitroolefins have been developed by utilizing a bifunctional tertiary-amine thiourea catalyst. The reactions accommodate ...
