We present a combined experimental and theoretical study of the interplay between the atomic structure and the magnon excitations in low dimensional ferromagnets. Two monolayer thick Fe films on W(110) with and without a Au buffer layer are investigated. Our experiments show that adding the Au layer leads to a significant softening of the magnons. First-principles calculations confirm the exper...

The actin filament-associated protein AFAP-110 is an actin cross-linking protein first identified as a substrate of the viral oncogene v-Src. AFAP-110 regulates actin cytoskeleton integrity but also functions as an adaptor protein that affects crosstalk between Src and PKC. Here we investigated the roles of AFAP-110 in the tumorigenic process of prostate carcinoma. Using immunohistochemistry of...

Gradient variations of through-thickness residual stress, microstructure and texture greatly affect the performance cold radial forged tubes. In this work, distribution stress was measured based on Debye ring. The characterized with electron backscattering diffraction technique. by X-ray diffractometer. influence strength anisotropy tubes different thickness reductions analyzed. results show th...

The in-plane density of phonon states of clean Fe(110) surface was measured separately for the first, second, and further atomic monolayers using nuclear inelastic scattering of synchrotron radiation. The results show that atoms of the first layer vibrate with frequencies significantly lower and amplitudes much larger than those in the bulk, and that vibrational spectra along two perpendicular ...

The step-step interactions on vicinal GaAs (110) surface patterns have been extracted from the quantitative analysis of the terrace width distribution (TWD). We have specifically studied the interactions in near-equilibrium faceting and kinetics-driven step bunching and meandering formed by spontaneous self-organization or through the modification of GaAs growth kinetics by atomic hydrogen. We ...

Various digital cellular standards were developed in several regional standards bodies during the late 1980s and early 1990s. The first-generation standards had been developed some ten years earlier. GSM The development of the new pan-European digital cellular standard got under way in 1985. GSM has since evolved into the leading global second-generation standard, in terms of number of subscrib...

Ordered titanium oxide films were prepared on an Mo(110) substrate under ultrahigh vacuum conditions and characterized by various vacuum surface analytical techniques. Using different preparation methods, the titanium oxide films exhibit two low-energy electron diffraction patterns: a (1×1) rectangular pattern and a (1×1) hexagonal pattern. Auger electron spectroscopy, high-resolution electron ...
