Protein length CCDFs in 22 organisms yield Tsallis q values that separate into superextensive, boundary, and subextensive regimes aligned with the bilaterian transition, with q rising monotonically in deuterostomes.
Proves finite-shot mean-squared-error laws for virtual distillation and symmetry verification that define certified operating windows and a selection trichotomy for their comparison.
A moment-based alternative to OLS for fractional polynomials achieves closed-form variance reduction for skewed errors by the factor g2 = 1 - gamma3^2/(2+gamma4) while preserving coverage and reverting to OLS under symmetry.
Presents ultra-low frequency spectral index maps for 22 bright extended radio galaxies showing indices of ~0.5 near cores rising to >1.0 in lobes for FR I sources and 0.5-0.9 in FR II hotspots.
A nine-compartment nonlinear model with two viral strains and PCHIP-based time-varying parameters is calibrated to Italian COVID-19 third-wave data, achieving high R^2 fits and proving analytical stability properties.
X-ray absorption edges indicate diffuse ISM dust towards GX 339-4 consists of Mg-rich amorphous pyroxene (Mg0.75Fe0.25SiO3) and metallic iron.
3D RHD simulations of FR0 jets in LEDA 55267 and LEDA 58287 show recollimation shocks driving compactness via turbulence and deceleration, with SED modeling predicting lepto-hadronic emission at TeV energies as a testable forecast.
A holographic f(Q) = ζ Q^n model yields slow-roll inflation consistent with Planck 2018 and late-time expansion compatible with CC+BAO data via CPL parametrization, with mild high-z deviations from ΛCDM.
MDL and BIC most reliably select low test-error models and recover ground-truth expressions in symbolic regression benchmarks.
