DNA mixture interpretation principles: insights from the NIST scientific foundation review

July 1, 2020
Author(s)
John Butler, Hariharan Iyer, Richard Press, Melissa Taylor, Peter Vallone, Sheila Willis
DNA mixture interpretation has become more challenging in recent years due to several factors including submission of more touch evidence samples to aid investigations and generation of more sensitive DNA test results with new STR typing kits. This

Proposed E57.02 Range Measurement Performance Standard for Medium Range 3D Imaging Systems

July 26, 2013
Author(s)
David MacKinnon, Luc Cournoyer, Kamel Saidi, Geraldine Cheok, Robert Bridges, Darin Ingimarson
We present the proposed standard ASTM E57.02 "Test Method to Evaluate the Range Measurement Performance of 3D Imaging Systems in the Medium Range" (Work Item ASTM WK12373). The stated purpose of the standard is to provide metrics and procedures to evaluate

Analytical and Experimental Assessment of Steel Truss Bridge Gusset Plate Connections

June 8, 2011
Author(s)
Mark A. Iadicola, Yavuz Mentes, Yoon D. Kim, Robert S. Zobel, Donald W. White, Roberto T. Leon, Justin M. Ocel
This paper focuses on findings from comprehensive studies of steel truss bridge gusset plate behavior and proposes practical design procedures. The studies include comparisons of analytical models to responses from large-scale experimental tests from

A Novel Test Method for Measuring Mechanical Properties at the Small-Scale: The Theta Specimen

June 9, 2005
Author(s)
George D. Quinn, Lin-Sien H. Lum, Dan Xiang, Ajitkumar Jillavenkatesa, Li Ma, Douglas T. Smith
A test method has been developed for measuring mechanical properties of material structures at the small-scale. Round or hexagonal rings are compressed vertically on their ends thereby creating a uniform tension stress in a horizontal crossbar that serves

Evaluating Building Integrated Photovoltaic Performance Models

May 1, 2002
Author(s)
Arthur H. Fanney, Brian P. Dougherty, Mark W. Davis
Predictive performance tools could accelerate the implementation of integrated photovoltaics (BIPV. The National Institute of Standards and Technology (NIST) seeks to improve and validate previously developed computer simulation tools with experimental

Performance and Characterization of Building Integrated Photovoltaic Panels

May 1, 2002
Author(s)
Arthur H. Fanney, Brian P. Dougherty, Mark W. Davis
Buildings consume more than two-thirds of the electricity in the United States. The incorporation of photovoltaics into the buildings, referred to as building integrated photovoltaics (BIPV), offers an aesthetically pleasing means of displacing centrally

Linkage-Specific Conformational Ensembles of Non-Canonical Polyubiquitin Chains

February 28, 2016
Author(s)
Carlos A. Castaneda, Apurva Chaturvedi, Christina M. Camara, Joseph E. Curtis, Susan T. Krueger, David Fushman
Polyubiquitination is a critical protein post-translational modification involved in a variety of processes in eukaryotic cells. The molecular basis for selective recognition of the polyubiquitin signals by cellular receptors is determined by the

… results for Round Robin VII were received March 5, 1986; the last results were received April 29, 1986. The first participant results for Round Robin VIII …

Confirmation of Interstellar Acetone

October 1, 2002
Author(s)
Lewis E. Snyder, Francis J. Lovas, David Mehringer, Nina Yanti Miao, Y J. Kuan, J M. Hollis
We present new observations of interstellar acetone [(CH3)(2) CO] from both the NRAO 12 m and the BIMA array. We report NRAO 12 m detections of 13 new acetone emission features that can be assigned to 20 acetone transitions. These assignments are based on

Orphan High Field Superconductivity in Non-Superconducting Uranium Ditelluride

April 19, 2024
Author(s)
Corey Frank, Sylvia Lewin, Gicela Saucedo Salas, Peter Czajka, Ian Hayes, Hyeok Yoon, Tristin Metz, Johnpierre Paglione, John Singleton, Nicholas Butch
Reentrant superconductivity is an uncommon phenomenon in which the destructive effects of magnetic field on superconductivity are mitigated, allowing a zero-resistance state to survive under conditions that would otherwise destroy it. Typically, the

A Novel Low Loss and Lightweight Magnetic Material for Electrical Machinery

February 10, 2020
Author(s)
Michael J. Donahue, Farzad Ahmadi, Yilmaz Sozer, Igor Tsukerman
A new low loss and light weight core material, with applications in electrical machinery, is made of highly packed and insulated magnetic microwires (MWs). These MWs are aligned in such a way as to guide the flux in rotor/stator, with the ultimate goal of
