Defining and detecting quantum speedup
... consensus may be time- and community-dependent [14]. In the absence of a consensus about what is the best classical algorithm, we define potential (quantum) speedup as a speedup compared to a specific classical algorithm or a set of classical algorithms.

Osmotic Properties of Protoplasts of Micrococcus
... In a medium of low osmotic pressure, the protoplasts imbibe water and, lacking mechanical rigidity and the restraint of the cell wall, they rupture. Since ( V o / K OD ) = V,/ V ,then the calculation of Vo/Kfrom equation (3)and Fig. 3, curve (2), as set out in the previous section, also enables the ...
