Lengthscale Effects on Exchange Coupling in Co-Pt Ll 0 +Ll 2 Nanochessboards

September 1, 2016
Author(s)
Eric P. Vetter, Liwei Geng, Priya Ghatwai, Dustin A. Gilbert, Yongmei Jin, William A. Soffa, Jerrold A. Floro
The Co-Pt nanochessboard is a quasi-periodic, nanocomposite tiling of Ll 0 and Ll 2 magnetic phases that offers a novel structure for the investigation of exchange coupling, relevant to permanent magnet applications. Periodicity of the tiling is controlled

Marie Curies Last Radium Standard Grand Challenge

September 1, 2016
Author(s)
Bert M. Coursey
The last of the radium-226 standards that Marie Curie personally handled is destined for a radioactive materials waste dump. Presented here is a history of the standards and a challenge to the scientific community to present a rationale for why this

Optimal joint detection and estimation that maximizes ROC-type curves

September 1, 2016
Author(s)
Adam J. Wunderlich, Bart Goossens, Craig K. Abbey
Combined detection-estimation tasks are frequently encountered in medical imaging. Hence, optimal methods for joint detection and estimation are of interest because they provide upper bounds on observer performance and can motivate practical image analysis

Should ontologies be evaluated?

September 1, 2016
Author(s)
Judith R. Gelernter, Jyoti Jha
Ontologies are semantic tools for Artificial Intelligence. Ontologies list and define objects in a domain and the relationship among objects such as to do reasoning within and among systems. Mistakes within ontologies bring system errors if their use in a
