% DESCRIPTION: Returns a proxy for toxicity of the drug applied at time k
% INPUT:
    % uk : drug applied at time k (uk = 1 is DMSO, uk = 2 is Tram, uk = 3 is BEZ, uk = 4 is Comb)
% OUTPUT: a proxy for toxicity of the drug applied at time k
% NOTE: proxy could also be the inverse of the 1-norm of the live-cell portion of A*
%           (higher toxicity for drugs that make pop shrink faster)
