B3-3: PCORI's National Clinical Research Network

Launching PCORnet, a national patient-centered clinical research network

The Patient-Centered Outcomes Research Institute (PCORI) has launched PCORnet, a major initiative to support an effective, sustainable national research infrastructure that will advance the use of electronic health data in comparative effectiveness research (CER) and other types of research. In December 2013, PCORI's board of governors funded 11 clinical data research networks (CDRNs) and 18 pa...

Creating a national home visiting research network.

Home visiting can play a key role in the early childhood system of services. For home visiting to achieve its potential, decision-makers must make informed choices regarding adoption, adaptation, coordination, scale-up, and sustainment. We need a coordinated, focused, and theory-based home visiting research infrastructure to inform such decisions. The transdisciplinary Home Visiting Research Ne...

Clinical Research: A Globalized Network

Clinical research has become increasingly globalized, but the extent of globalization has not been assessed. To describe the globalization of clinical research, we used all (n = 13,208) multinational trials registered at ClinicalTrials.gov to analyzed geographic connections among individual countries. Our findings indicate that 95% (n = 185) of all countries worldwide have participated in multi...

National Patient-Centered Clinical Research Network (PCORnet) Phase I: Final Evaluation Report

Conjugacy Classes of 3-braid Group B3

In this article we describe the summit sets in B3, the smallest element in a summit set and we compute the Hilbert series corresponding to conjugacy classes. The results will be related to Birman-Menesco classification of knots with braid index three or less than three.
