BACKGROUND When patients with end-stage renal disease (ESRD) miss their routine intermittent hemodialysis (IHD), electrolyte abnormalities and volume overload often occur. An institutional protocol to ensure that patients receiving IHD have elective surgeries scheduled within 24 hours after their dialysis may reduce procedural delays or cancellations caused by hyperkalemia and hypervolemia afte...

We use iterations of elementary embeddings derived from countably complete ideals on ω1 to provide a uniform proof of some classical results connecting the number of models of cardinality א1 in various infinitary logics to the number of syntactic types over the empty set. We introduce the notion of an analytically presented abstract elementary class (AEC), which allows the formulation and proof...
