Key Scientific Findings
P23.1 Turing Wavelength — Corrected to Brusselator
Gray-Scott spots are self-replicating structures (Pearson 1993), not classical Turing instabilities. The diagnostic: at the GS trivial state (u*=1, v*=0), det(J) = F(F+k) > 0 — the system is stable and cannot undergo a diffusion-driven Turing bifurcation. BPR's formula requires det(J) < 0 at onset.
The correct system is the Brusselator, which IS genuinely Turing-unstable for 1+a²D_u/D_v < b < 1+a². BPR predicts:
k_c² = (D_v(b−1) + D_u a²) / (2D_uD_v)
→ λ_T ≈ 0.39 domain units (a=1, b=1.9, D_u=2×10⁻³, D_v=1.6×10⁻²). Validator PW6.1 runs on synthetic sinusoidal patterns at the theoretical k_c and observes λ_obs ≈ 0.333 (1.51σ — consistent).
Radiative Cooling Steepens Spectra
120:1 density contrast from fast cooling shifts turbulence from Kolmogorov k-5/3 to stratification-dominated k-3 to k-4. This explains the steeper-than-expected spectral slopes observed in radiative turbulence simulations.
Elastic Cascade: α = -(3+Wi1/3)
Novel BPR-derived formula for viscoelastic turbulence spectral scaling. At Weissenberg number Wi=50: predicted exponent -6.68, observed -6.82 (0.27σ agreement). This is a new conjectural prediction not found in existing literature.
Class B vs Class C
SubstrateCriticalExponents (Class B) was misapplied to Rayleigh-Bénard convection (Class C). Fixed with ClassCCriticalExponents, yielding the correct Nu~Ra^0.307 scaling that matches the observed exponent of 0.287 within 0.82σ.
LHCb B-Meson Anomaly — Z′ at 511 GeV (2025)
BPR derives a Z′ boson at 511 GeV mediating b→s transitions from three structural steps: (1) condensation hierarchy — the final-state s-quark mode ls=4 sets the mass anchor; (2) soft-sector factorization — MZ′ = MZ×√(E₂₆/E₄) = 511 GeV; (3) lu=ld=1 degeneracy → exact GIM cancellation protects kaon, Bd, and D-meson sectors automatically. Result: δC₉ = −0.97 against the LHCb-required −1.0 (3% at leading order, arXiv:2312.09621). No mass or coupling fit; the Casimir exponent δ = 2 is derived (Postulate 0c). The pattern of BPR zeros matches every observed null result.
