Shop scheduling problems under precedence constraints
, 1997 The paper considers a scheduling model that generalizes the well-known open shop, flow shop, and job shop models. For that model, called the super shop, we study the complexity of finding a time-optimal schedule in both preemptive and non-preemptive ...

Perfect Matching Under Precedence Constraints
NetworksABSTRACT In this article, we motivate and define variants of perfect matching under precedence constraints where a perfect matching is built incrementally and precedence constraints ensure that an edge may only be added to the matching if the edge's predecessor vertices have already been covered. We study the complexity of the problem

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Two Case Studies in Phonological Universals: A View from Artificial Grammars
Biolinguistics, 2010 This article summarizes the results of two experiments that use artificial grammar learning in order to test proposed phonological universals. The first universal involves limits on precedence-modification in phonological representations, drawn from a ...

Advancing Stroke Clinical Trials Using Community Engagement and Implementation Science Approaches
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Stroke clinical trials are essential for advancing stroke care but can face challenges with recruitment, retention, clinical relevance, and translation into real‐world practice. We propose that integrating community engagement and implementation science approaches into stroke trials can help address these needs.

Precedence-constrained covering problems with multiplicity constraints
, 2023 We study the approximability of covering problems when the set of items chosen to satisfy the covering constraints must form an ideal of a given partial order. We examine the general case with multiplicity constraints, where item i can be chosen up to di

A new type of problem to stabilize an assembly setup [PDF]
Management Science Letters, 2011 Traditional assembly lines are still attractive means of mass and large-scale series production. Previous research works mainly dealt with the minimization of balancing loss, subject to precedence constraints. Very recently the focus of attention shifted

Arthritis Care &Research, EarlyView.Objective To support high‐quality, patient‐centered care for systemic lupus erythematosus (SLE), the American College of Rheumatology (ACR) developed evidence‐based measures incorporating clinical and patient‐reported outcome measures (PROMs). Using the Consolidated Framework for Implementation Research (CFIR), we conducted semistructured interviews ...

Reducing Disjunctive Precedence Constraints Based on Symmetry
, 2007 Symmetry can be used to reduce the search effort for finding a solution to problems containing disjunctive precedence constraints. We propose an efficient preprocessing technique for these problems by using graph theory. The set of precedence constraints
