Least squares residual power series solutions for Kawahara and Rosenau-Hyman nonlinear wave interactions with applications in fluid dynamics
In this section, we will outline the general procedure of the LSRPS technique, as described in46,47 for solving time-fractional differential equations. This technique combines the classical (RPS) method with the least-squares method.
Residual…

Reversible control over the distribution of chemical inhomogeneities in multiferroic BiFeO3
We grew epitaxially strained (001)p.c.-oriented La0.15Bi0.85FeO3 films with a thickness of 100 nm on a 14-nm-thick SrRuO3 buffer layer on top of (110)o-oriented single-crystalline DyScO3 substrates using pulsed laser deposition. Here, we chose…

Topological links and knots of speckled light mediated by coherence singularities
Within a coherent light field, a point exhibiting zero intensity and an indeterminate phase is referred to as a phase singularity. In the context of the polarization dimension, a point characterized by an undefined polarization vector is referred…

Probabilistic alignment of multiple networks
Probabilistic formulation of the problem of aligning multiple networks
Consider K network observations, with N nodes each and adjacency matrices {Ak; , k = 1, …, K }. We consider networks that are directed and with binary edges (that…

Defying 60 Years of Physics – “Strange Metals” Break the Rules of Electricity
Strange metals challenge the 60-year-old theory that electric current consists of a flow of discrete charges. Strange metals show electricity carried by a quantum fluid rather than discrete electrons, challenging the long-standing Fermi liquid…
