Combined effects of the damping and forcing in underdamped time-delayed Duffing oscillator are considered this paper. We analyze generation a certain damping-induced unpredictability, due to gradual suppression interwell oscillations. find minimal amount amplitude right frequency revert effect dissipation, so that oscillations can be restored, for different time delay values. This is achieved b...

The present study introduces a novel curve-fitting algorithm for surface plasmon resonance (SPR) curves using a self-constructed, wedge-shaped beam type angular interrogation SPR spectroscopy technique. Previous fitting approaches such as asymmetric and polynomial equations are still unsatisfactory for analyzing full SPR curves and their use is limited to determining the resonance angle. In the...

The Gaussian spin–spin relaxation time T2G, as determined by nuclear magnetic resonance (NMR) spin-echo decay measurements, is found to be useful for diagnosis of quantum critical behaviour in heavy-fermion systems. Combining T2G with the spin–lattice relaxation time T1, the exponent f of the quantity T1T=T 2 2G T is predicted to be sensitive to the type of quantum criticality in the system con...

Metallic nanoparticles can exhibit very large optical extinction in the visible spectrum due to localized surface plasmon resonance. Spherical plasmonic nanoparticles have been the subject of numerous studies in recent years due to the fact that the scattering response of spheres can be analytically evaluated using Mie theory. However a major disadvantage of metallic spherical nanoparticles is ...
