Evidence for Open Field Lines from Active Regions: Short Communication

Interacting Open Wilson Lines from Noncommutative Field Theories 1

In noncommutative field theories, it was known that one-loop effective action describes propagation of non-interacting open Wilson lines, obeying the flying dipole’s relation. We show that two-loop effective action describes cubic interaction among ‘closed string’ states created by open Wilson line operators. Taking d-dimensional λ[Φ]⋆-theory as the simplest setup, we compute nonplanar contribu...

Clinical Outcomes of Open versus Arthroscopic Surgery for Lateral Epicondylitis, Evidence from a Systematic Review

Background: Lateral epicondylitis (LE) also known as tennis elbow is a common disease of middle-aged population.Surgery is a treatment of choice in patients not responded to the conservative management. Open and arthroscopicrelease are the two main choices for LE surgery; however, an overall consensus is not available. This study was aimedto compare the clinical outcomes after conventional open...

Harnessing Free External Resources: Evidence from the Open Source Field

The present study employs a knowledge-based view of the firm, within the larger framework of the resource-based theory, and gathers insights from social exchange theory to investigate how firms might influence the deployment of free resources by entities external to them. The authors use data from 109 open source software projects involving 110 firms to test hypotheses about whether firm-contro...
