Response modification factor - Review paper
Abstract Response modification factor (R) has a main function in the seismic design of new construction materials and is a seismic design parameter in equivalent static analysis. It determines the nonlinear performance of building structures during strong earthquakes.

Coherent Backscattering of Light with Nonlinear Atomic Scatterers [PDF]
We study coherent backscattering of a monochromatic laser by a dilute gas of cold two-level atoms in the weakly nonlinear regime. The nonlinear response of the atoms results in a modification of both the average field propagation (nonlinear refractive ...

Extended Skyrme interaction (I): spin fluctuations in dense matter [PDF]
Most of the Skyrme interactions are known to predict spin or isospin instabilities beyond the saturation density of nuclear matter which contradict predictions based on realistic interactions. A modification of the standard Skyrme interaction is proposed

Damping modification factors for acceleration response spectra
DMF (Damping modification factors) are used to modify elastic response spectral values corresponding to damping ratio 5% to other damping levels. The influence of seismological parameters (magnitude, epicentral distances and site conditions) on DMF for acceleration spectra was analysed.
