A method of RF inhomogeneity correction in MR imaging
A direct postprocessing method for correcting RF inhomogeneity in MR imaging is proposed. First, two images with different flip-angles of θ and 2θ are obtained. Next, the spatial distribution maps of the sensitivity of the surface coil and the B 1 field intensity are produced by employing those images. Finally, the correction of the MR …

The near-surface effect manifested as a static shift of the low-frequency parts of the apparent resistivity curve without affecting the corresponding parts of the impedance-phases curve. Sometimes, there are two orders of magnitudes in static effect, which is similar to the square ratio of normal field and abnormal field of the electric field.

Effect on the thermal conductivity inhomogeneity of clay …
The standard deviation of surface 1 and surface 4 increased to 0.4580 mm and 0.5674 mm, respectively. The roughness of surface 2 and surface 3 also increased, but the standard deviation was only 0.0893 mm and 0.0956 mm, which was caused by the shedding of loose mineral particles on the surface of the sample.
Surface Inhomogeneity of Graphene Oxide Influences …
The Aβ peptides exhibit a remarkable tendency in binding to the scattered interfaces between unoxidized and oxidized regions, which induces the dissociation of Aβ amyloid fibril. These findings should deepen our understanding of surface-induced peptide dissociation and stimulate discovery of alternative AD treatments.

A phase shifting interferometer using a tunable laser as a light source is proposed for measuring shapes of both surfaces of a glass plate and the distribution of refractive index. To separate the superimposed interferograms generated with many wavefronts reflected from the plate, the phase shift associated with the wavelength shift is applied in the …

With the increase of inhomogeneity depth, the influence on temperature field near the contact region becomes weaker. When the inhomogeneity is far away from the surface, the influence of inhomogeneity on the temperature field can be ignored.
