Soliton crystals in Kerr microresonators

July 18, 2016
Author(s)
Daniel C. Cole, Erin S. Lamb, Pascal P. Del'Haye, Scott A. Diddams, Scott B. Papp
Solitons are pulses which propagate without spreading due to a balance between nonlinearity and dispersion or diffraction, and are universal features of systems exhibiting these effects. They are important in plasma physics, fluid dynamics, atomic physics

A STATISTICAL APPROACH TO ESTIMATING A 95 % CONFIDENCE LOWER LIMIT FOR THE DESIGN CREEP RUPTURE TIME VS. STRESS CURVE WHEN THE STRESS ESTIMATE HAS AN ERROR UP TO 2 % (*)

July 17, 2016
Author(s)
Jeffrey T. Fong, James J. Filliben, Nathanael A. Heckert, Pedro V. Marcal, Marvin J. Cohn
Recent experimental results on creep-fracture damage with minimum time to failure (minTTF) varying as the 9th power of stress, and a theoretical consequence that the coefficient of variation (CV) of minTTF is necessarily 9 times that of the CV of the

Semantification of Identifiers in Mathematics for Better Math Information Retrieval

July 17, 2016
Author(s)
Moritz Schubotz, Alexey Grigoriev, Howard Cohl, Norman Meushke, Bela Gipp, Volker Markl
Mathematical formulae are essential in science, but face challenges of ambiguity, due to the use of a small number of identifiers to represent an immense number of concepts. Corresponding to word sense disambiguation in Natural Language Processing, we

An azeotropic cross-linked styrene-methacrylate network formed through rapid visible-light photo- polymerization

July 15, 2016
Author(s)
Yin Yang, Aaron A. Urbas, Andres Gonzalez-Bonet, Richard J. Sheridan, Jonathan E. Seppala, Kathryn L. Beers, Jirun Sun
A system containing well-defined functional material, a clinically practical procedure to make the material in situ, and proper analytical tools for chemical structure and kinetic studies is appealing, but currently unavailable. Herein, we introduce an all

First principles search for n-type oxide thermoelectrics

July 15, 2016
Author(s)
Kevin F. Garrity
Oxides have many potentially desirable characteristics for thermoelectric materials, including low cost and stability at high temperatures, but thus far there are few known high zT n-type oxide thermoelectrics. In this work, we use high-throughput first

Thermophysical Properties of the Marine Microalgae Nannochloropsis salina

July 15, 2016
Author(s)
Nico Schneider, Tara Fortin, Roland Span, Mandy Gerber
Algae have a variety of uses, including pharmaceutical and cosmetic products, and as a potential energy source in the form of biodiesel, bioethanol and biogas. To optimize the commercial production and use of algal biomass, production facilities have to be

Time Propagation of Partial Differential Equations Using the Short Iterative Lanczos Method and Finite-Element Discrete Variable Representation: An Experiment Using the Intel Phi Coprocessors

July 15, 2016
Author(s)
Barry I. Schneider, klaus Bartschat, Xiaoxu Guan
The Short Iterative Lanczos (SIL) method has been combined with the Finite-Element Discrete Variable Representation (SIL-FEDVR) to yield a powerful approach to solving the time-dependent Schroedinger equation. It has been applied to the interaction of

Direct Three-Dimensional Observation of the Microstructure and Chemistry of C3S Hydration

July 14, 2016
Author(s)
Qinang Hu, Mohammed Aboustait, Taehwan Kim, Tyler Ley, Jay C. Hanan, Jeffrey W. Bullard, Robert Winarski, Volker Rose
While portland cement has been widely studied for over 100 years, there are still widespread disagreements on the mechanisms of hydration. One reason for this is that direct observation of the change in microstructure and chemistry are challenging for many

Modeling early breakdown failures of gate oxide in SiC power MOSFETs

July 14, 2016
Author(s)
Zakariae Chbili, Asahiko Matsuda, Jaafar Chbili, Jason T. Ryan, Jason P. Campbell, Mhamed Lahbabi, D. E. Ioannou, Kin P. Cheung
One of the most serious technology roadblocks for SiC DMOSFETs is the significant occurrence of early failures in time-dependent-dielectric-breakdown (TDDB) testing. Conventional screening methods have proved ineffective because the remaining population is

Quasi-Elastic Neutron Scattering Studies of Hydrogen Dynamics for Nanoconfined NaAlH 4

July 14, 2016
Author(s)
Shathabish NaraseGowda, Craig Brown, Madhu Sudan Tyagi, Tabbetha A. Dobbins
The hydrogen dynamics of nano-confined sodium alanate (NaAlH 4) has been studied using quasi-elastic neutron scattering (QENS). Results indicate thermodynamic destabilization is responsible for reduced desorption temperatures of NaAlH 4 upon confinement

Refined treatment of single-edge diffraction effects in radiometry

July 14, 2016
Author(s)
Eric L. Shirley
This work treats diffraction corrections in radiometry for cases of point and extended sources in symmetric three-element systems. It considers diffraction effects for both spectral power and total power in cases of Planckian sources. This improves upon an

ThermoData Engine (TDE) Version 10.1 (Pure Compounds, Binary Mixtures, Ternary Mixtures, and Chemical Reactions): NIST Standard Reference Database 103b

July 14, 2016
Author(s)
Vladimir Diky, Chris D. Muzny, Alexander Y. Smolyanitsky, Ala Bazyleva, Robert D. Chirico, Joe W. Magee, Yauheni Paulechka, Andrei F. Kazakov, Scott A. Townsend, Eric W. Lemmon, Michael D. Frenkel, Kenneth G. Kroenlein
The ThermoData Engine is a software expert system implementing the concept of dynamic data evaluation for thermophysical and thermochemical properties of, primarily, organic compounds. This new release provides a substantially expanded database of

Towards a Lifecycle Information Framework and Technology in Manufacturing

July 14, 2016
Author(s)
Thomas D. Hedberg, Allison Barnard Feeney, Moneer M. Helu, Jaime A. Camelio
Industry has been chasing the dream of integrating and linking data across the product lifecycle and enterprises for decades. However, industry has been challenged by the fact that the context in which data is used varies based on the function in the

Documentation for ROC Baseline 2016

July 13, 2016
Author(s)
James R. Matey, Su L. Cheng, Patrick J. Grother, Mei L. Ngan, George W. Quinn, Elham Tabassi, Craig I. Watson
We present ROC baseline data to support the recommendations in Matey et al [6].

Improving Security and Software Management through the use of SWID Tags

July 13, 2016
Author(s)
David A. Waltermire, Larry Feldman, Gregory A. Witte
This bulletin summarized the information presented in NISTIR 8060, "Guidelines for the Creation of Interoperable Software Identification (SWID) Tags". The publication provides an overview of the capabilities and usage of SWID tags as part of a

Is the Factor of 10 Still Applicable Today?

July 13, 2016
Author(s)
Simone N. Gittelson, John S. Buckleton
The assignment of the weight of DNA evidence depends on a number of factors (allele probability estimates, the population genetic model used, the value of the coancestry coefficient, etc.). One of these factors is the allele probability estimates from a
