The present study describes a method using immunohistochemical labeling in combination with high-resolution imaging (field emission scanning electron microscopy) to investigate the spatial localization of amelogenins on apatite crystallites in developing porcine enamel. Cross-sections of developing enamel tissue from freeze-fractured pig third molar were treated with antiserum against recombina...

ELF is a function of the 3D-coordinates which is large in the regions where orbitals localize. It is closely related to LOL and the Fermi hole mobility function. While it has been used with considerable success for analyzing the chemical bond in molecules and crystals, it seems to have some intrinsic limits, which are discussed. q 2005 Elsevier B.V.

We investigate the localization property of an electron in the disordered two-chain system (ladder model) with long-range correlation as a simple model for electronic property in DNA sequence. The chains are constructed by repetition of the sugarphosphate sites, and the inter-chain hopping at the sugar sites come from nucleotide pairs, i.e., A− T or G−C pairs. It has been found that some DNA se...

Many-body localization, the persistence against electron-electron interactions of the localization of states with nonzero excitation energy density, poses a challenge to current methods of theoretical and numerical analyses. Numerical simulations have so far been limited to a small number of sites, making it difficult to obtain reliable statements about the thermodynamic limit. In this paper, w...

We study the three-dimensional Anderson model of localization with anisotropic hopping, i.e., weakly coupled chains and weakly coupled planes. In our extensive numerical study we identify and characterize the metal-insulator transition by means of the transfer-matrix method. The values of the critical disorder Wc obtained are consistent with results of previous studies, including multifractal a...

We have previously proposed that further improved functionals for density functional theory can be constructed based on the Armiento-Mattsson subsystem functional scheme if, in addition to the uniform electron gas and surface models used in the Armiento-Mattsson 2005 functional, a model for the strongly confined electron gas is also added. However, of central importance for this scheme is an in...

Magnetotransport measurements are performed on an aluminum thin film grown on a GaAs substrate. A crossover from electron- to hole-dominant transport can be inferred from both longitudinal resistivity and Hall resistivity with increasing the perpendicular magnetic field B. Also, phenomena of localization effects can be seen at low B. By analyzing the zero-field resistivity as a function of temp...

Theoretical descriptions of alkylidene chalcogen difluorides have been performed on their planar (1-3) and bent (4-6) conformations. The planar T-shaped conformations were the most stable ones, from the calculations performed (Gaussian-G2 and B3LYP/6-311+G). The bonding nature of the T-shaped (C(2)(v)()) structures has also been analyzed by means of the atoms in molecules (AIM) theory and elect...

We investigate the electronic properties in Bloch electron on a square lattice with vacancies uniform magnetic field. show that single vacancy site introduced to system creates defect energy level every innumerable fractal gap Hofstadter butterfly. The wavefunctions of different levels have all localization lengths depending their generations, and they can be described by universal function aft...
