A graph is dually chordal if it is the clique graph of a chordal graph. Alternatively, a graph is dually chordal if it admits a maximum neighbourhood order. This class generalizes known subclasses of chordal graphs such as doubly chordal graphs, strongly chordal graphs and interval graphs. We prove that Vizing's total-colour conjecture holds for dually chordal graphs. We describe a new heuristi...

This highlight describes the characteristics and inpatient utilization of under age 65 disabled California Medicare beneficiaries by dual eligible status (i.e., Medicaid State buy-in coverage or not). More disabled dually eligible beneficiaries are younger, non-White, and in fee-for-service (FFS) than non-dually eligible beneficiaries. Disabled dually eligible beneficiaries experienced consiste...

Individuals eligible in both Medicaid and Medicare, the dually eligible enrollees, account for a disproportionate share of Medicaid utilization and payments. While comprising 14.7 percent of the Medicaid population, they accounted for 40.5 percent of Medicaid payments in 2002. Mean reimbursement for the dually eligible enrollees was nearly four times that of non-dually eligible Medicaid enrolle...

The variety \(\mathbb{DHMSH}\) of dually hemimorphic semi-Heyting algebras was introduced in 2011 by the second author as an expansion a dual hemimorphism. In this paper, we focus on from logical point view. paper presents extensive investigation logic corresponding to and its axiomatic extensions, along with equally universal algebraic study their semantics. Firstly, present Hilbert-style axio...

In this paper we define and study a family of codes which come close to be MRD codes, so we call them AMRD codes (almost MRD). An AMRD code is a code with rank defect equal to 1. AMRD codes whose duals are AMRD are called dually AMRD. Dually AMRD codes are the closest to the MRD codes given that both they and their dual codes are almost optimal. Necessary and sufficient conditions for the codes...

Administrative data were used to compare lengths of stay, Medicare payment, total and average daily costs, discharge destinations, rehospitalizations, and emergency room (ER) use of dually eligible and non-dually eligible Medicare inpatients admitted for a psychiatric diagnosis. Regressions controlled for State buy-in coverage as a proxy for dual eligibility, hospital type, and beneficiary soci...
