Coalition formation is a fundamental type of interaction that involves the creation of coherent groupings of distinct, autonomous, agents in order to efficiently achieve their individual or collective goals. Forming effective coalitions is a major research challenge in the field of multi-agent systems. Central to this endeavour is the problem of determining(More)
Heteroplasmic cells, harboring both mutant and normal mitochondrial DNAs (mtDNAs), must accumulate mutations to a threshold level before respiratory activity is affected. This phenomenon has led to the hypothesis of mtDNA complementation by inter-mitochondrial content mixing. The precise mechanisms of heteroplasmic complementation are unknown, but it(More)
Conditional preference networks (CP-nets) are recently an emerging topic as a graphical model for compactly representing ordinal conditional preference relations on multi-attribute domains. As we know, the treewidth, which can decrease the solving complexity for many intractability problems, is exactly a fundamental property of a graph. Therefore, we can(More)
Mogroside IIE is a bitter triterpenoid saponin which is the main component of unripe Luo Han Guo fruit and a precursor of the commercially available sweetener mogroside V. In this study, we developed an enzymatic glycosyl transfer method, by which bitter mogroside IIE could be converted into a sweet triterpenoid saponin mixture. The reactant concentration,(More)
