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

Stabilizing Superionic-Conducting Structures via Mixed-Anion Solid Solutions of Monocarba-Closo-Borate Salts

Wan Si NMN Tang, Koji Yoshida, Alexei V. Soloninin, Roman V. Skoryunov, Olga A. Babanova, Alexander V. Skripov, Mirjana NMN Dimitrievska, Vitalie Stavila, Shin-Ichi Orimo, Terrence J. Udovic
Solid lithium and sodium closo-polyborate-based salts are capable of superionic conductivities surpassing even liquid electrolytes, but often only at above-ambient temperatures where their entropically driven disordered phases become stabilized. Here we
