In this paper, we present results on the noise performance of the waveguide Niobium Titanium Nitride (NbTiN) superconducting hot electron bolometer (HEB) mixers, cryogenically cooled by a 4-K close-cycled refrigerator. The NbTiN superconducting HEB mixer is fabricated on a crystalline quartz substrate, and is mounted in a waveguide mixer block for RF and LO coupling. At 0.81 THz, the uncorrecte...
tumor growth has a number of features in common with a physical process known as molecular beam epitaxy (mbe). so using the same equations for tumor growth is sensible. however, tumor substrate unlike mbe is not planar that makes necessary a geometrical treatment of the growth equations. a variety of mathematical models have been proposed to describe tumor growth. the justification for these mo...
