On the Impacts of In-Band LTE Emissions

January 3, 2018
Author(s)
Azizollah Kord
Abstract—With the introduction of low-power internet of things (IoT) and device to device (D2D) communications in the long time evolution (LTE) system protocol, the in-band interference from other user equipment (UE) with higher power requires special

On the Susceptibility of Coded OFDM to Interference: A Simulation Study

January 3, 2018
Author(s)
Jason Coder, Yao Ma
The susceptibility of broadband wireless communications signals (e.g., LTE, IEEE 802.11) to interference has been a topic of significant research. In this paper, we implement a simulation-based study on the impact interference can have on the bit error

Relativistic all-order many-body calculation of energies, wavelengths, and M1 and E2 transition rates for the 3d^n configurations in tungsten ions

January 3, 2018
Author(s)
M S. Safronova, U I. Safronova, S. G. Porsev, M G. Kozlov, Yuri Ralchenko
Energy levels, wavelengths, magnetic-dipole and electric-quadrupole transition rates between the low-lying states are evaluated for W51+ to W54+ ions with 3dn (n = 2 to 5) electronic con gurations using an approach combining con guration interaction with

Validation of ATR FT-IR to identify polymers of plastic marine debris, including those ingested by marine organisms

January 3, 2018
Author(s)
Melissa R. Jung, F. D. Horgen, Sara Orski, Viviana Rodriguez Cardenas, Kathryn Beers, George H. Balazs, T. T. Jones, Thierry M. Work, Kayla C. Brignac, Sarah-Jeanne Royer, K. D. Hyrenbach, Brenda A. Jensen, Jennifer Lynch
Polymer identification of plastic marine debris can help identify its sources, degradation, and fate. We optimized and validated a fast, simple, and accessible technique, attenuated total reflectance Fourier transform infrared spectroscopy (ATR FT-IR), to

Letter in response to V. Stodden et al., Science 354, 1240 (2016).

January 2, 2018
Author(s)
Mark W. Maciejewski, Adam D. Schuyler, Michael R. Gryk, Ion I. Moraru, Pedro R. Romero, Eldon L. Ulrich, Hamid R. Eghbalnia, Miron Livny, Frank Delaglio, Jeffrey C. Hoch
Stodden et al. (1) bring welcome attention to the problem of reproducibility of computational analyses, and recommend guidelines for addressing the barriers to reproducibility. However, one important barrier to long-term reproducibility of computational

Psst, Can you Keep a Secret?

January 2, 2018
Author(s)
Apostol T. Vassilev, Nicky W. Mouha, Luis T. A. N. Brandao
The security of encrypted data depends not only on the theoretical properties of cryptographic primitives but also on the robustness of their implementations in software and hardware. Threshold cryptography introduces a computational paradigm that enables

Activity measurements of the radionuclides 18F and 64Cu for the NIST, USA in the ongoing comparisons BIPM.RI(II)-K4.F-18 and BIPM.RI(II)-K4.Cu-64

January 1, 2018
Author(s)
Denis E. Bergeron, Jeffrey T. Cessna, Ryan P. Fitzgerald, Leticia S. Pibida, Brian E. Zimmerman, Carine Michotte, Manuel Nonis, Andrew Fenwick, Kelly Ferreira, John Keightley
In 2016, comparisons of activity measurements of 18F and 64Cu using the Transfer Instrument of the International Reference System (SIRTI) took place at the National Institute of Standards and Technology (NIST, USA). This is the first SIRTI comparison for

Correction of an adding-doubling inversion algorithm for the measurement of the optical parameters of turbid media

January 1, 2018
Author(s)
Paul Lemaillet, Catherine C. Cooksey, Jeeseong Hwang, Heidrun Wabnitz, Dirk Grosenick, Lin Yang, David W. Allen
We present broadband measurements of the optical properties of tissue-mimicking solid phantoms using a single integrating sphere to measure the hemispherical reflectance and transmittance under a direct illumination at the normal incident angle. These

Incorporating an Optical Clock into a Time Scale

January 1, 2018
Author(s)
Jian Yao, Thomas E. Parker, Neil Ashby, Judah Levine
This paper discusses how to build a time scale with an intermittently-operated optical clock. In particular, it gives suggestions on how long and how often to run an optical clock. It also explores the benefits of having an optical clock in a time scale

Rheological Properties of Jute-Based Cellulose Nanofibers under Different Ionic Conditions

January 1, 2018
Author(s)
Lihong Geng, Ali Naderi, Yimin NMN Mao, Chengbo Zhan, Priyanka Sharma, Xiangfang Peng, Benjamin S. Hsiao
Cellulose nanofibers (CNF) were produced by 2,2,6,6-tetramethylpiperidinyl-1-oxyl (TEMPO) -oxidation and mechanical shearing of jute pulp. The cross section dimension of CNFs was determined by small-angle neuron scattering (SANS), yielding a width of about
