Finding a heaviest vertex-weighted triangle is not harder than matrix multiplication [PDF]
, 2009 We show that a maximum-weight triangle in an undirected graph with n vertices and real weights assigned to vertices can be found in time O(n(omega) + n(2+o(1))), where omega is the exponent of the fastest matrix multiplication algorithm. By the currently

The Risk of Cardiovascular Diseases for Shift Workers in the Prospective Heinz Nixdorf Recall Study
American Journal of Industrial Medicine, EarlyView.ABSTRACT Background Shift work can disrupt circadian rhythms and is postulated to play a role in cardiovascular diseases (CVD). In the German prospective population‐based Heinz Nixdorf Recall Study, we analyzed longitudinal associations between shift work and night‐shift work with CVD.

Importance of directed acyclic graphs in medical education
Discover EducationMedical students are taught the importance of variable relationships in scientific research. We propose augmenting this education with teaching about direct acyclic graphs (DAGs)—a graphical model used to analyze complex systems of variables.

Arthritis &Rheumatology, EarlyView.Objective To examine the association between radiographic structural damage and physical function (PF) in psoriatic arthritis (PsA). Methods Data were analyzed from a large longitudinal PsA cohort. PF was measured using the Health Assessment Questionnaire (HAQ, 0–3) and Short Form‐36 PF subscale (SF‐36, 0–100); radiographic joint damage was measured ...

Optimizing Iterative Data-Flow Scientific Applications Using Directed Cyclic Graphs
IEEE Access, 2023 Data-flow programming models have become a popular choice for writing parallel applications as an alternative to traditional work-sharing parallelism. They are better suited to write applications with irregular parallelism that can present load imbalance.

Arthritis &Rheumatology, EarlyView.Objective The purpose of this study was to estimate the prevalence of difficult‐to‐manage (D2M) and treatment‐refractory (TR) axial spondyloarthritis (axSpA) and to identify factors associated with D2M and TR disease in a longitudinal cohort. Methods We performed a cross‐sectional analysis on data from the Schroeder Arthritis Institute Spondylitis ...

British Journal of Clinical Pharmacology, EarlyView.Prior glucocorticoid exposure is associated with modestly increased vancomycin clearance in hospitalized children, partly mediated by renal function and inflammation and may contribute to subtherapeutic early drug exposure. Abstract Introduction Augmented renal clearance (ARC) can lead to subtherapeutic vancomycin exposure in children.
