The Block Preconditioned SOR Method for Solving Indefinite Complex Linear Systems
Numerical Linear Algebra with Applications, Volume 33, Issue 1, February 2026.ABSTRACT In this paper we extend the theory of a block preconditioned SOR method studied by Hezari, Edalaptour, and Salkuyeh (2015) for the solution of indefinite complex linear systems. In particular, we consider the case where the key matrix S$$ S $$ has real eigenvalues which lie in (−∞,+∞)$$ \left(-\infty, +\infty \right) $$ and not only in [0,+∞)$$

An Overview of Scale Invariance in Proton Structure With Holographic Insights
Advances in High Energy Physics, Volume 2026, Issue 1, 2026.The concept of self‐similarity in the internal structure of the proton, rooted in scale invariance and fractal geometry, provides an intriguing framework for understanding the behavior of parton distribution functions (PDFs), particularly in the small x region probed in deep inelastic scattering (DIS).

Discoveries in ultra-peripheral collisions: Past, present, future [PDF]
EPJ Web of ConferencesUltra-relativistic heavy-ion collisions produce extremely strong electromagnetic field which provide a uniquely intense and energetic source of photons. The photons manifest from such ultra-Lorentz contracted electromagnetic fields have, in recent years,

Mass Spectra, Radii, and Decay Widths of Toponium
Advances in High Energy Physics, Volume 2026, Issue 1, 2026.In this work, the radial Schrodinger equation with a nonrelativistic quark potential model (NRQPM) is solved numerically by employing the shooting method. Calculated numerical wave functions (or solutions) are used to compute the masses, root mean square (RMS) radii, E1, M1 radiative transition widths, annihilation decay widths, and branching ratios of
