Fair cake-cutting is the division of a cake or resource among N users so that each user is content. Users may value a given piece of cake differently, and information about how a user values different parts of the cake can only be obtained by requesting users to “cut” pieces of the cake into specified ratios. Many distributed computing problems which involve resource sharing can be expressed as...
متن کاملReductive Coupling of H - H , H - C , and C - C Bonds from Pd Complexes
Reductive coupling to form H-H, C-H, and C-C bonds from transition-metal complexes is of fundamental importance in many catalytic processes. However, despite numerous experimental' and theoretical2 studies, there remain a number of puzzles concerning these processes. For example, reductive elimination of methane from Pt(H)(CH3)(PPh3), is quite facile at -25 'C,ld while Pt(CH3)2(PPh,)2 is qkite ...
متن کاملAdiabatic TOCSY for C,C and H,H J-transfer.
Adiabatic pulses have been widely used for broadband decoupling and spin inversion at high magnetic fields. In this paper we propose adiabatic pulses and supercycles that can be used at high magnetic fields like 800 or 900 MHz to obtain broadband TOCSY sequences with C,C or H,H J-transfer. The new mixing sequences are equal or even superior to the well known DIPSI-2,3 experiments with respect t...
متن کاملC–H Functionalization
C–H Functionalization has the potential to become a paradigmshifting strategy for organic synthesis. Over the last decade, the field has experienced explosive growth and a large variety of new C–H functionalization methodologies have been developed. In particular, regioselective functionalization of sp2 C–H bonds has become a broadly flexible approach for the synthesis of complex aromatic carbo...
