H  R  Csp

A large number of interesting combinatorial optimization problems like M3SAT, MC fall under the class of constraint satisfaction problems. Recent work by one of the authors [34] identifies a semidefinite programming relaxation that yields the optimal approximation ratio for every CSP, under the Unique Games Conjecture. In this work, we present an efficient rounding scheme that achieves th...

Asymmetric Formation of Quaternary Carbon Centers Catalyzed by Novel Chiral 2,5-Dialkyl-7-phenyl-7-phosphabicyclo- [2.2.1]heptanes

Many important biologically active compounds contain quaternary carbon centers. Efficient asymmetric syntheses of these compounds represent a significant challenge in organic chemistry.1 Some catalytic synthetic methods directed toward this problem include prolinecatalyzed aldol reactions,2 Michael additions,3 alkylations with phase-transfer catalysts,4 palladium-catalyzed allylations,5 Heck re...

Cover Feature Outlook

Cover Feature Physiological Computing

Brain−computer interfaces (BCIs) hold great promise for improving information delivery and preserving user attention, but this promise has not yet translated to practical use. A prototype BCI that optimizes email notifications in noisy, complex environments, CARSON combines multiple measures from the brain to predict both cognitive workload and message relevancy to determine the optimum time to...
