Errors and uncertainties in finite element method (FEM) computing can come from the following eight sources: (1) Computing platform; (2) choice of element types
Silver nanomaterials (AgNMs) have been increasingly used in consumer products for their antibacterial properties. Textiles, including wound dressings, are just
We report on Mueller matrix bidirectional reflectance distribution function (BRDF) measurements of a sintered polytetrafluoroethylene (PTFE) sample over the
In future quantum communication systems, single photons will be required to possess very narrow linewidths and accurate wavelengths for efficient interaction
