With the congestion and scarcity of available spectrum resources, spectrum sharing between long-term evolution (LTE) and the IEEE 802.11 (aka. WLAN) systems is an ongoing research topic. Considering the LTE license assisted access (LAA) with the listen

This paper addresses the problem of classifying materials from microspectroscopical images at each pixel. The challenges lie in identifying discriminatory spectral features and obtaining accurate and interpretable models relating spectra and class labels
Microwave magnetodynamics in ferromagnets are often studied in the limit of small-amplitude modes that modulate a well-defined magnetic state. However, strongly nonlinear regimes, where the aforementioned limits are not applicable, have become

While graphene has substantial commercial potential, numerous aspects regarding its potential ecological effects such as its potential for bioaccumulation are not well known. 14C-labeled few layer graphene (FLG) was spiked to artificial freshwater and the

Developing functional concrete mixtures with less ordinary portland cement (OPC) has been one of the key objectives of the 21st century sustainability movement. While the supply of many alternatives to OPC (such as fly ash or slag) may be limited, those of

The realization of atomic quantum gases has brought out surprising effects that have no correspondence in nonlinear optics with thermal gases, presenting intriguing and exciting challenges to the research discipline of nonlinear optics which has matured
We describe preliminary models for the viscosity, thermal conductivity, and surface tension for pure fluids that are constituents of four surrogate fuels for ultralow-sulfur diesel fuels developed under the auspices of the Coordinating Research Council

Neutron reflectometry (NR) is uniquely suited for studying protein interaction with phospholipid bilayers. While molecular details along the bilayer normal can be obtained on an Angstrom scale, NR cannot discern specific membrane-bound protein regions due
Standardization, control, and calibration provide different degrees of certainty about the data acquired with an instrument. Each process is aimed at assuring that results from the instrument have the quality required for the intended purpose. The purpose

The new applications for carbon nanotubes (CNTs) in various fields and consequently the increase in their production volume have increased their potential release to the environment. Landfills are one of the major locations where carbon nanotubes are

Scaling analysis of several thousand Nb3Sn critical-current (Ic) measurements is used to derive the extrapolative scaling expression (ESE), a global fitting equation that can quickly and accurately extrapolate (or interpolate) limited datasets to obtain

A Fourier transform spectrum of sulfur dioxide 33S16O2 has been recorded in the 18.3 µm spectral region at a resolution of 0.002 cm-1 using a Bruker IFS 125HR spectrometer leading to the observation of the ν2 and 2ν2- ν2 vibrational bands of the 33S16O2

As mechanical testing proceeds towards ever-decreasing length scales, the ultimate limit is the atomic scale. Here, we investigate the atomic-scale interactions that occur at the diamond- nickel interface during the earliest stages of a Ni nanoindentation
We investigate the role of the electric field and its normal derivative in three-dimensional electromagnetic scattering theory. In particular, we present an alternative integral equation formulation that uses the electric field and its normal derivative as
Supply chain management is critically dependent on trusted email with authentication systems that work on a global scale. Solutions to date have not adequately addressed the issues of email forgery, confidentiality, and sender authenticity. The IETF DANE

In this paper we propose a new method for calculating the rise time of pulse generators and oscilloscopes using a correction factor. This new method is advantageous over the well known geometric rule, also known as the root sum of squares (RSS) rule
