We have compared the validity of application of the spatial dispersion theories of Pekar and Agarwal in the case of the reflection spectra of PbI2, in which a big effect was supposed to allow accurate measurements. Our analysis shows in fact that the big effect is essentially due to the so-called “Hopfield potential barrier,” which could produce it even without any spatial dispersion in the crystal...
Congenital muscular dystrophies with hypoglycosylation of α-dystroglycan (α-DG) are a heterogeneous group of disorders often associated with brain and eye defects in addition to muscular dystrophy. Causative variants in 14 genes thought to be involved in the glycosylation of α-DG have been identified thus far. Allelic mutations in these genes might also cause milder limb-girdle muscular dystrophy...
Radio-spectroscopy of millimeter region enables to research separation of energetic levels in crystal fields, to measure Electron Paramagnetic Resonance in materials of high anisotropy, to research antiferromagnetics and semiconductors, to work out quantum generators in millimeter and sub-millimeter regions. We obtained experimental results on different materials in the range of wave lengths from...
