From Square Tiles to Algebraic Inequalities,rt of different chains. We thus ignore all excluded volume effects, essentially treating a model chain at its Θ-point. We first consider the correlations among individual segments of the chain (Sect. 3.1), which are all found to be given by simple Gaussian functions. We then discuss the segment dens

Post-Malthusian Dilemmas in Agriculture 4.0,rst we identify the macroscopically relevant length scales, and we use dimensional analysis to write the observables as functions of dimensionless combinations of these variables. Here the essential assumption is that no microscopic scales like ℓ come in and that we identified all macroscopic scales

Can we construct a better version of the theory, clearly distinguishing universal from model-dependent features?

For quantitative calculations we of course have to specify the . factors, and as pointed out in Sect. 11.1, we have some freedom there. We will use the scheme of ‘dimensional regularization’ and ‘minimal subtraction’. This scheme is most efficient for act
