In this article, we propose an axiomatic system for fuzzy “cardinality” measures (referred to as fuzzy c-measures for short) assigning to each finite fuzzy set a generalized cardinal that expresses the number of elements that the fuzzy set contains. The system generalizes an axiomatic system introduced by J. Casasnovas and J. Torrens (2003). We show that each fuzzy c-measure is determined by tw...

We conducted a descriptive study examining the health status of dually eligible beneficiaries using a sample from the Medicare Health Outcomes Survey (HOS), a measure of health status administered to enrollees in Medicare managed care (MMC). Overall, we found that dually eligible beneficiaries were sicker, more depressed, and reporting more pain than Medicare-only beneficiaries. Our results sug...

Many architectural languages have been proposed in the last fifteen years, each one with the chief aim of becoming the ideal language for specifying software architectures. What is evident nowadays, instead, is that architectural languages are defined by stakeholder concerns. Capturing all such concerns within a single, narrowly focused notation is impossible. At the same time it is also imprac...

This study focused on persons 65 years of age and over who were dually entitled to Medicare and Medicaid in 1978. The paper examines their age, sex, and race characteristics, and their Medicare utilization and mortality rates in comparison to persons eligible for Medicare only. The study showed that the group entitled to both Medicare and Medicaid was relatively much older than those with Medic...

Many works related to dually chordal graphs, their cliques and neighborhoods were published. We will undertake a similar study but by considering minimal separators and their properties. Moreover we find new characterizations of dually chordal graphs.

Two residential programs for dually diagnosed (severely mentally ill and substance abusing) homeless individuals in Philadelphia were compared in a quasi-experimental field study. Findings indicate that the experimental model, a hybrid psychosocial and drug rehabilitation program, did significantly better in maintaining clients in care and in successful rehabilitation than the comparison model,...

We investigate questions in quantum information geometry which concern the existence and non-existence of dual and dually flat structures on stratified sets of density operators on finite-dimensional Hilbert spaces. We show that the set of density operators of a given rank admits dually flat connections for which one connection is complete if and only if this rank is maximal. We prove moreover ...

We provide a new modus operandi for the computation of the nucleolus in cooperative games with transferable utility. Using the concept of dual game we extend the theory of characterization sets. Dually essential and if the game is monotonic dually saturated coalitions determine both the core and the nucleolus whenever the core is non-empty. We show how these two sets are related to the existing...

A graph G is dually chordal if there is a spanning tree T of G such that any maximal clique of G induces a subtree in T . This paper investigates the Colourability problem on dually chordal graphs. It will show that it is NP-complete in case of four colours and solvable in linear time with a simple algorithm in case of three colours. In addition, it will be shown that a dually chordal graph is ...
