The N -Koszul algebras are N -homogeneous algebras satisfying a homological property. These algebras are characterised by their Koszul complex: an N -homogeneous algebra is N -Koszul if and only if its Koszul complex is acyclic. Methods based on computational approaches were used to prove N -Koszulness: an algebra admitting a side-confluent presentation is N -Koszul if and only if the extra-con...

We evaluated the expression of the FLK1, one of the lateral mesoderm early markers where cardiogenesis occurs, to characterize and isolate cardiac stem/progenitor cells from ES cells. Dissociated cells from embryoid bodies (EBs) on day 3, 4, or 5 were collected into two subpopulations with or without FLK1 expression and coculture on OP9 stromal cells was continued to examine whether contracting...

This study examined the distributive effect of different contracting types on primary health services provision between the poor and non-poor in rural Afghanistan. METHOD Contract...
