The bicinchoninic acid assay ( BCA assay ), also known as the Smith assay, after its inventor, Paul K. Smith at the Pierce Chemical Company, [1] now part of Thermo Fisher Scientific, is a biochemical assay for determining the total concentration of protein in a solution (0.5 μg/mL to 1.5 mg/mL), similar to Lowry protein assay, Bradford protein ...
Biconical antenna. In radio systems, a biconical antenna is a broad- bandwidth antenna made of two roughly conical conductive objects, nearly touching at their points. [1] Biconical antennas are broadband dipole antennas, typically exhibiting a bandwidth of three octaves or more. A common subtype is the bowtie antenna, essentially a flattened ...

Bionic contact lens. A bionic contact lens is a proposed device that could provide a virtual display that could have a variety of uses from assisting the visually impaired to video gaming, as claimed by the manufacturers and developers. [1] The device will have the form of a conventional contact lens with added bionics technology in the form of ...
Their heights above the ground correspond to their values. In mathematics, bicubic interpolation is an extension of cubic spline interpolation (a method of applying cubic interpolation to a data set) for interpolating data points on a two-dimensional regular grid. The interpolated surface (meaning the kernel shape, not the image) is smoother ...
