Higher-order effects on flow and transport in randomly heterogeneous, statistically anisotropic porous media
A higher-order theory is presented for steady state, mean uniform saturated flow and nonreactive solute transport in randomly homogeneous, statistically anisotropy natural log hydraulic conductivity fields Y. General integral expressions are derived for the spatial covariance of fluid velocity to …

The phonon spectra of simple metals - higher order effects of the electron-ion interaction
… periodic ionic lattice on the electrons. These effects are calculated by expanding the phonon dynamical matrix in powers of the electron-ion interaction and truncating the series in accord with the two-umk1app approximation rather than the homogeneous response approximation. In the former, some …

Higher-order effects in the elastic scattering of electrons and positrons from lead-208 and carbon-12
… Any deviations observed can be attributed to higher-order processes sensitive to the sign of the charge of the scattered particle. The beam energies were $\sim$450 MeV and the angular ranges covered were 26-37$\sp\circ$ for $\sp{12}$C and 26-53$\sp\circ$ for $\sp{208}$Pb. No deviations were …

Design of CMOS Four-Quadrant Gilbert Cell Multiplier Circuits in Weak and Moderate Inversion
… remove drift current components and to address higher order effects such as ideality factor mismatch, threshold mismatch, body effect, and short channel effects, is important to provide a linear multiplier. It is also shown that distortion caused by device size mismatch and offset input currents …
