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 کاملDr Jekyll and Mr C
Jekyll is a high level programming language that can be translated losslessly to and from human readable, human editable C. This makes it possible to maintain Jekyll and C versions of the same file, with any changes made to one file being automatically reflected into the other. By being losslessly inter-translatable with C, Jekyll reduces the switching costs normally associated with moving to a...
متن کاملH/C MR spectroscopic imaging of regionally specific metabolic alterations after experimental stroke
Loss of function and subsequent spontaneous recovery after ischaemic stroke are associated with functional and structural alterations in brain tissue. Acute functional tissue damage involves distortion of key metabolic processes, such as oxidative glycolysis and neurotransmittermetabolism.Nevertheless, initially perturbedmetabolismmay be restored at later stages, e.g. in perilesional areas, whi...
متن کاملHyperpolarized (13)C MR Angiography.
Magnetic resonance angiography (MRA) is a non-invasive technology that can be used for diagnosis and monitoring of cardiovascular disease; the number one cause of mortality worldwide. Hyperpolarized imaging agents provide signal enhancement of more than 10, 000 times, which implies large reduction in acquisition time and improved spatial resolution. We review the role of hyperpolarized 13C agen...
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 ...
