A characterization of the Total Graph of Interval Graphs and Proper Interval Graphs
Mapana Journal of SciencesAn asteroidal triple is a stable set of three vertices such that each pair is connected by a path avoiding the neighbourhood of the third vertex. Let G be a graph with vertex set V (G) and edge set E(G), the total graph T(G) of G has vertex set V (G)∪E(G) and two vertices in T(G) are adjacent if and only if they are adjacent or incident in G.

Arthritis Care &Research, EarlyView.Objective We developed a novel electronic health record sidecar application to visualize key rheumatoid arthritis (RA) outcomes, including disease activity, physical function, and pain, via a patient‐facing graphical interface designed for use during outpatient visits (“RA PRO dashboard”).

Consensus Strategies for Signed Profiles on Graphs
The median problem is a classical problem in Location Theory: one searches for a location that minimizes the average distance to the sites of the clients. This is for desired facilities as a distribution center for a set of warehouses. More recently, for

Minimum proper interval graphs
, 1995 A graph G is a proper interval graph if there exists a mapping r from V(G) to the class of closed intervals of the real line with the properties that for distinct vertices v and w we have r(v) ⋔ r(w) ≠ Ø if and only if v and w are adjacent and neither of

Arthritis Care &Research, EarlyView.Objective Knee osteoarthritis (OA) commonly affects individuals with type 2 diabetes (T2DM) and is associated with increased risk of diabetes‐related complications. To better understand potential mechanisms, we examined the association between symptomatic knee OA and glycemic control in individuals with T2DM.

Associations of Sleep and Shift Work With Osteoarthritis Risk
Arthritis Care &Research, EarlyView.Objective Daily rhythms may be critical for maintaining homeostasis of joint tissues. We aimed to investigate the relationships among circadian clock disruption, sleep, and osteoarthritis (OA) risk in humans. Methods In the UK Biobank, a prospective 500,000–person cohort, we evaluated associations among sleep duration, sleeplessness/insomnia, and shift

Axiomatic characterization of the interval function of partial cubes and partial Hamming graphs
AKCE International Journal of Graphs and CombinatoricsInterval function of a graph is a well-known notion in metric graph theory and the axiomatic characterization using a set of first order axioms of different graph classes is an interesting problem in this area.

A characterization of graphs with interval two-step graphs [PDF]
, 1993 One of the intriguing open problems on competition graphs is determining what digraphs have interval competition graphs. In this paper we consider this problem for the class of loopless symmetric digraphs.

End vertices in interval graphs
, 1988 Given an interval representation of an interval graph G, an interval is an end interval if its right (or left) endpoint is further to the right (left) of all other intervals in the collection. We characterize those vertices v in interval graphs for which

Arthritis Care &Research, EarlyView.Objective The objective of this study was to describe the longitudinal disease course and pulmonary outcomes of North American patients with melanoma differentiation–associated protein 5 (MDA5) antibody–associated dermatomyositis (DM). Methods Thirty patients with MDA5 antibody–associated DM were identified in a single‐center longitudinal cohort of 352
