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

Joint real and redshift space analysis of CosmicFlows-4++ yields BAO scales of 132±8 h^{-1}Mpc (real) and 139±7 h^{-1}Mpc (redshift) at z=0.07 together with fσ8=0.344±0.105.
A new methodology counts galaxy pairs over entire fields and uses k-means patches plus oversampled bootstrap covariance to produce more robust cross-correlation measurements for magnification bias studies in GAMA fields.
