Network Dynamics of a Fractional-Order Phase-Locked Loop with Infinite Coexisting Attractors
Complexity, 2020 We have investigated a fractional-order phase-locked loop characterised by a third-order differential equation. The integer-order mathematical model of the phase-locked loop (PLL) is first converted to fractional order using the Caputo-Fabrizio method ...

Chemistry – An Asian Journal, Volume 21, Issue 12, 26 June 2026.LiF grows on diindenoperylene not as a smooth film but as sparse, inhomogeniety associated nanoparticles that evolve stochastically toward full coverage, perturbing the interface while leaving the organic lattice intact. ABSTRACT Small‐molecule π$\pi$‐conjugated semiconductors provide an ordered platform for probing interfacial mechanisms in organic ...
