Characterization of Orbits in Bars in Disc Galaxies Using Fourier Frequencies

Abstract Bars are among the most prominent dynamical structures in disc galaxies, yet their long-term evolution and the orbital families that sustain them remain only partially understood. In this work, we introduce a new methodology based on frozen potentials combined with Fouri...

Multifactorial ecological framework for intestinal-type gastric cancer

Gastric cancer (GC) remains one of the leading causes of cancer-related mortality worldwide, with projections indicating increasing incidence and marked geographic variability across populations. Although multiple hypotheses have been proposed to explain this heterogeneity, inclu...
