First joint 2PCF+3PCF full-shape analysis on BOSS DR12 real data improves σ(h) by ~29%, σ(ω_cdm) by ~10%, and σ(A_s) by ~24% over 2PCF alone via extra BAO information in 3PCF triangles.

DICES combines binary-space-partition equal-area jackknives, correlation-matrix shrinkage, and delete-2 diagonal correction to yield non-singular, debiased covariances for Euclid clustering and weak-lensing spectra, cutting relative error 33% (covariance) and 48% (correlation) versus plain jackknife
