Recent measurements of emissions of methane from residential natural gas appliances have indicated non-negligible emissions within residences, with impacts on both indoor air quality and climate. As a result, methane losses from residential buildings have
This report provides supplemental information to NISTIR 8351 DNA Mixture Interpretation: A NIST Scientific Foundation Review and summarizes information from publicly accessible validation data and proficiency test results covering DNA mixture
Electron tomography is a powerful tool for the three-dimensional characterization of materials at the nano- and atomic-scales. A typical workflow for tomography involves several pre-processing steps that may include spatial binning, image registration, and
A set of approximate first-order ordinary differential equations was derived from the general dynamic equation (GDE) to study the aerosol dynamics with homogeneous nucleation and condensational diffusion-limited growth in an isothermal batch reactor. A

Commutable secondary certified reference materials (CRMs) play an essential role in the calibration hierarchy of many in-vitro diagnostic measurement procedures used in the medical laboratory. Therefore, sustainable availability of these CRMs is crucial to
This report documents a series of fire experiments performed within steel electrical enclosures and on open "ladder back" cable trays. The first objective is to measure the heat release rates and qualitatively understand the burning behavior of circuit

One of the most common polymers in commercial photovoltaic (PV) backsheets is polyvinylidene fluoride (PVDF). However, recent reports have shown the potential for PVDF-based backsheets to crack and fail prematurely. Previous work has suggested that polymer
This paper considers the ill-posed data assimilation problem associated with hyper- bolic/parabolic systems describing 2D coupled sound and heat flow. Given hypothetical data at time T > 0, that may not correspond to an actual solution of the dissipative
