Reconfigurable intelligent surfaces (RIS) have been recently introduced to optical wireless communication (OWC) networks resolve skip areas and improve the signal-to-noise ratio at user's end. In OWC networks, RIS are based on mirrors or metasurfaces. Metasurfaces evolved significantly over last few years. As a result, coding, digital, programmable, information metamaterials developed. The adva...

The determination of isocyanates concentrations in air is complicated by thepresence of these substances as monomers and oligomers as well as in thevapor and aerosol phases. Direct-reading instruments (DRIs) are available fordetermining the diisocyanate concentrations in workplace air, but they arecalibrated for the monomers only. Industry uses polymeric diisocyanateswhich c...

Nutrient standards such as the Dietary Reference Intakes (DRIs) may be used to assess diets of both individuals and of population groups. The goal is to estimate the probability of dietary adequacy (or inadequacy) for an individual and the prevalence of dietary adequacy for a group. The DRI that is needed to estimate the probability of dietary adequacy is the estimated average requirement for a...
