Identifying uncertainty in laser powder bed fusion additive manufacturing models

September 4, 2016
Author(s)
Felipe F. Lopez, Paul W. Witherell, Brandon M. Lane
As additive manufacturing (AM) matures, models are beginning to take a more prominent stage in design and process planning for AM. A limitation frequently encountered in AM models is a lack of indication about their precision and accuracy. Often overlooked

Inhibition of DNA glycosylases in development of cancer therapeutics

September 4, 2016
Author(s)
M Miral Dizdar, Pawel Jaruga, Erdem Coskun, Marcus J. Calkins, Nathan Donley, Dorjbal Dorjsuren, Anton Simeonov, Amanda K. McCullough, R S. Lloyd, Ajit Jadhav
In cancer therapy, the efficacy of therapeutic agents may be influenced by increased DNA repair capacity. This may be due to overexpression of DNA repair proteins that repair therapy-induced DNA lesions in tumors before they become toxic. Inhibition of DNA

The Paradigm Shift in Smart Manufacturing System Ar-chitecture

September 4, 2016
Author(s)
Yan Lu, Frank H. Riddick, Nenad Ivezic
In response to demanding market conditions, Smart Manufacturing (SM) seeks to integrate advanced manufacturing methods, operational technologies (OT), and information and communication technologies (ICT) to drive the creation of manufacturing systems with

Structural and Dynamical Trends in Alkali-Metal Silanides Characterized by Neutron-Scattering Methods

September 2, 2016
Author(s)
Wan Si NMN Tang, Mirjana NMN Dimitrievska, Jean-Noel Chotard, Wei Zhou, Raphael Janot, Alexander V. Skripov, Terrence J. Udovic
Structural, vibrational, and dynamical properties of the mono- and mixed-alkali silanides (MSiH 3, where M=K, Rb, Cs, K 0.5Rb 0.5Cs 0.5, and Rb 0.5Cs 0.5) were investigated by various neutron experiments, including neutron powder diffraction (NPD), neutron

Virtual Factory Framework for Supporting Production Planning and Control

September 2, 2016
Author(s)
Deogratias Kibira, Guodong Shao
Developing optimal production plans for smart manufacturing systems is challenging if events change dynamically. A virtual factory incorporating engineering tools, simulation, and optimization generates and communicates performance data to guide wise

Certified DNA Reference Materials to Compare HER2 Gene Amplification Measurements Using Next- Generation Sequencing Methods

September 1, 2016
Author(s)
Chih-Jian Lih, Robin D. Harrington, Kneshay Harper, David J. Sims, Paul McGregor, Corinne Camalier, Han Si, Biswajit Das, P. M. Williams, Hua-Jun He, Jamie L. Almeida, Steven Lund, Steven J. Choquette, Kenneth D. Cole
The National Institute of Standards and Technology (NIST) Standard Reference Materials 2373 is a set of genomic DNA samples prepared from five breast cancer cell lines with certified values for the ratio of the HER2 gene copy number to the copy numbers of

Defense Mechanisms and Nutrient Displacement in Arabidopsis thaliana upon Exposure to CeO2 and In2O3 Nanoparticles

September 1, 2016
Author(s)
Bryant C. Nelson, Sanem Hosbas Coskun, Chuanxin Ma, Hong Li, Huiyuan Guo, Craig Musante, Jason C. White, Baoshan Xing, Om P. Dhankher
Metal-based nanoparticles (NPs) can cause toxicity to terrestrial plants, however there is little understanding of plant defense mechanisms that may counteract nanotoxicity. In the present study, we investigated the defense mechanisms of Arabidopsis

Forbidden Phonon: Dynamical Signature of Bond Symmetry Breaking in the Iron Chalcogenides

September 1, 2016
Author(s)
David M. Fobes, Igor A. Zaliznyak, John M. Tranquada, Zhijun Xu, Genda D. Gu, Xu-Gang He, Wei Ku, Yang Zhao, Masaaki Matsuda, V. Ovidiu Garlea, Barry Winn
Investigation of the inelastic neutron scattering spectra in Fe 1+yTe 1-xSe x near a signature wave vector Q = (1,0,0) for the bond-order wave (BOW) formation in parent compound Fe 1+yTe reveals an acoustic-phonon-like dispersion present in all structural

Guest Editors Introduction: Cybersecurity or Privacy

September 1, 2016
Author(s)
Irena V. Bojanova, Jeffrey M. Voas
Cybersecurity is a major concern. Governments’, industry, and even hospitals’ IT infrastructure is being penetrated with increasing frequency and sophistication. The growth of mobile and IoT devices and amateur software only add to that. But, privacy is

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
