Minimum cost spanning tree problems try to connect agents e¢ ciently to a source when agents are located at di¤erent points in space and the cost of using an edge is …xed. We examine solution concepts to divide the common cost of connection among users, and revisit the dispute between two of the most familiar solutions: the Kar and folk solutions, both based on the familiar Shapley value. We ch...

Fulminant hepatic failure (FHF), associated with high mortality, is characterized by extensive death of hepatocytes and hepatic dysfunction. There is no effective treatment for FHF. Several studies have indicated that flavonoids can protect the liver from different factor-induced injury. Previously, we found that the extracts of Elaeagnus mollis leaves had favorable protective effects on acute ...

The essential oil isolated from fresh aerial parts of Hypericum perforatum L. was analyzed by GC and GC/MS. One hundred and thirty four identified compounds accounted for 98.7% of the total oil. The main components of the oil were: germacrene D (18.6%), (E)-caryophyllene (11.2%), 2-methyloctane (9.5%), α-pinene (6.5%), bicyclogermacrene (5.0%) and (E)-β-ocimene (4.6%). The volatile profile of H...
