Chapter 4: Oxidatively induced DNA damage: Mechanisms and measurement

November 20, 2020
Author(s)
Miral M. Dizdar, Erdem Coskun, Gamze Tuna, Melis Kant, Pawel Jaruga
Oxidatively induced damage to DNA occurs in living organisms by endogenously or exogenously generated reactive species including free radicals. Mounting evidence suggests that this type of DNA damage plays an important role in the etiology of numerous

Evolution of the Magnetic Properties in the Antiferromagnet Ce 2 RhIn 8 Simultaneously Doped with Cd and Ir

D. S. Christovam, G. S. Freitas, M. M. Piva, J. C. Souza, M. O. Malcolms, O. L. Canton, Juscelino Leao, William D. Ratcliff, Jeffrey W. Lynn, C. Adriano, P. G. Pagliuso
We report the evolution of the magnetic properties of Ce 2Rh 1−xIr xIn 8−yCd y single crystals. In particular, for Ce 2Rh 0.5Ir 0.5In 8 (T N = 2.0 K) and Ce 2Rh 0.5Ir 0.5In 7.79Cd 0.21 (T N = 4.2 K), we have solved the magnetic structure of these compounds

Formalizing Performance Evaluation of Mobile Manipulator Robots using CTML

November 20, 2020

Suleyman Gundogdu, J. P. Clancy, Guangyong Xu, Yang Zhao, Paul A. Dube, Tufan C. Karalar, Beong K. Cho, Jeffrey W. Lynn, M. Ramazanoglu
The rare earth magnetic order in pure and doped Er (1−x)Ho xNi 2B^2^C (x = 0, 0.25, 0.50, 0.75, 1) single crystal samples was investigated using magnetization and neutron diffraction measurements. Superconducting quaternary borocarbides, RNi 2B 2C where R

An Initial Look at Federal Offices of Research and Technology Applications

November 19, 2020
Author(s)
Nicole K. Gingrich, Michael J. Hall, Isaac Patterson
In Science—the Endless Frontier, Vannevar Bush wrote that reaping the potential benefits of science conducted at federal laboratories requires the discoveries made in the labs be transferred to society. In federal laboratories, Offices of Research and

Experimental demonstration of the near-quantum optimal receiver

November 19, 2020
Author(s)
Jabir Marakkarakath Vadakkepurayil, Ivan Burenkov, FNU Nur Fajar Rizqi Annafianto, Abdella Battou, Sergey Polyakov
We implement the cyclic quantum receiver based on the theoretical proposal of Roy Bondurant and demonstrate experimentally below the shot-noise limit (SNL) discrimination of quadrature phase-shift keying signals (PSK). We also experimentally test the

GAA-GAA Coexistence in the CBRS Band: Performance Evaluation of Approach 3

November 19, 2020
Author(s)
Anirudha Sahoo, Weichao Gao
The General Authorized Access (GAA) users operate at the lowest priority in the Citizens Broadband Radio Service (CBRS) band. So they must not cause harmful interference to the higher priority users. In addition, the GAA users must cooperate with each

INFORMATION MODEL FOR A-UGV PERFORMANCE MEASUREMENT STANDARD

November 19, 2020
Author(s)
Soocheol Yoon, Roger V. Bostelman
Automatic through autonomous - Unmanned Ground Vehicles (A-UGVs) have the potential to be applied over a wide range of manufacturing systems under industry 4.0 paradigm. In order to use A-UGVs efficiently in a manufacturing system, it is necessary to

Isotope shift spectroscopy of the 1S0 to 3P1 and 1S0 to 3P0 transitions in strontium

November 19, 2020
Author(s)
Gretchen K. Campbell, Hirokazu Miyake, Neal Pisenti, Peter Elgee, Ananya Sitaram
Isotope shift spectroscopy with narrow optical transitions provides a benchmark for atomic struc- ture calculations, and has also been proposed as a way to constrain theories predicting physics beyond the Standard model. Here, we have measured frequency

Calibration Procedures for Orthogonal Superposition Rheology

November 18, 2020
Author(s)
Ran Tao, Aaron M. Forster
Orthogonal superposition (OSP) rheology is an advanced rheological technique that involves superimposing a small-amplitude oscillatory shear deformation orthogonal to a primary shear flow. This technique allows the measurement of structural dynamics of

DIGITAL TWIN FOR SMART MANUFACTURING: THE PRACTITIONER'S PERSPECTIVE

November 18, 2020
Author(s)
Maja Barring, Guodong Shao, Bjorn Johansson
The manufacturing sector is experiencing a technological paradigm shift, where new digital technologies can help digitalize product design, production systems, and manufacturing processes and generate more data. One of the essential technology concepts for

EFFECTS OF PRE-STRAIN ON THE NON-LINEAR VISCOELASTIC PROPERTIES OF A MODEL SEALANT

November 18, 2020
Author(s)
Christopher C. White, Donald L. Hunston, Kar tean Tan
The non-linear viscoelastic properties of a model sealant were measured using stress relaxation tests conducted at different strain levels, x. Some specimens were measured with no previous strain history while others were given a preconditioning that

Estimating the Impact of 16 CFR Part 1633 on Bed Fire Outcomes

Author(s)
Stanley W. Gilbert, David Butry, Rick D. Davis, Richard Gann
Effective July 1, 2007, the U.S. Consumer Product Safety Commission promulgated a standard to severely reduce the heat release rate and the early heat output from mattresses and foundations when ignited by a flaming ignition source. This study estimates

The Roles of Standard Cigarettes in Assuring the Ignition Resistance of Soft Furnishings

November 18, 2020
Author(s)
Richard G. Gann, Ickchan Kim, Steven P. Lund, William F. Guthrie, Rick D. Davis
Regulations for cigarette ignition resistance (CIR) of soft furnishings (beds and upholstered furniture) and less fire-prone cigarettes have contributed substantially to the decrease in losses from cigarette-initiated fires over time. Two Standard
