dc:description "For each generation G from 2 to 24 the script builds one binary network: 2^G terminals, area-preserving radii, and vessel lengths in geometric ratio 2^(-1/3). Primary service volume and total terminal flow are both exactly 2^G, so each of the 22 successive local exponents is log(2)/log(2) = 1 and the ordinary-least-squares slope on those generations is 1. Tube volume is the sum of the cylindrical vessel volumes in units of pi r_c^2 l_c, computed at 80 decimal places and checked against the closed geometric series. The pass rule uses only the primary exponents; the tube-volume exponents are reported beside them.";
<http://www.w3.org/2000/01/rdf-schema#comment> "Measured: 1 dimensionless local exponent (n = 22, 0; exact on every primary pair). Interpretation: Terminal flow is one unit per terminal, so metabolic rate equals the number of terminals, 2^G. Each terminal service volume is one fixed unit (a sphere whose diameter is the fixed terminal length, up to a factor that cancels in every ratio); the primary service volume is their sum, 2^G. Area-preserving radii mean the two daughters have cross-sections adding to the parent. The space-filling length ratio 2^(-1/3) is taken from the companion formalization's hypotheses and is used only to set tube lengths. The method's phrase for the primary volume and its phrase for the critique's service-volume assumption name the same invariant-terminal sum in Kozłowski and Konarzewski (2004). The quantity the 3/4 derivation sets proportional to mass is total tube volume, so that volume is the reported alternative and is not substituted into the pass rule. ThompsonLaws.Magnitude states the cube law (weightOfLength, this claim) and the surface-to-mass law; it does not contain an infinite-generation branching theorem. No animal is represented.";
