Hole Transfer Energetics in Structurally Distorted DNA: The Nucleosome Core Particle
, 2006
"... The dynamics of long-range hole transport (HT) through DNA are critically dependent on the relative energies of guanine radical cation states. Electrostatic contacts with protein fragments and changes in the secondary structure of the DNA helix are expected to directly influence the stability of a g ..."

between the DNA nucleobases and the surrounding protein and water atoms and the structural changes in DNA arising from compaction into a NCP affect the energetics of hole transfer between guanine sites. We find that structural distortions of DNA can have dramatic consequences for the stability of a
REVIEWS Subtle StructuralDistortions inSome Dielectric Perovskites
"... Abstract | Dielectric perovskites exhibit a range of interesting phenomenon such as ferroelectricity, piezoelectricity, pyroelectricity, which have important technological implications. These materials show strong structure–property correlations. Majority of the perovskites exhibit crystal structure ..."

structures, which can be described in terms of distortions of the cubic prototype. In some cases the distortions are extremely weak and impossible to detect by x-ray diffraction (even at synchrotron sources). In such cases, use of complementary techniques, such as neutron powder diffraction and electron

Local Structural Distortions in InAsPDnP Strained Layer Superlattices
"... Abstract: The local structure around As in thin InAsXP1-, strained layers in InAsxPl., /InP superlattices has been probed by fluorescence detected XAFS as a function of composition, and compared to that found in unstrained, bulk samples of similar composition. Contributions up to the third coordinat ..."

of the grown layer (pseudomorphic growth). The question of how the distortion of the unit cell of the strained layer influences the local atomic structure is still open and very few theoretical studies related to this problem are found in the literature [5]. Local atomic investigations on similar strained
Quality evaluation of motion estimation algorithms based on structural distortions
"... Abstract-In this paper a methodology for understanding the effectiveness of motion estimation techniques is presented. Unlike other performances evaluation systems, that are based on measuring the errors between the actual and the predicted displacements, the proposed technique is inspired to the H ..."

to the Human Visual System. More in detail, the perceptual impact of geometric distortions induced by non accurate motion estimation is considered by means of an objective measure of the perceived distortion impact. Some of the most common block-based motion estimation algorithms have been tested. For each

Full-Reference Video Quality Assessment Considering Structural Distortion and No-Reference Quality Evaluation of MPEG Video
- in Proc. IEEE Int. Conf. Multimedia
, 2002
"... There has been an increasing need recently to develop objective quality measurement techniques that can predict perceived video quality automatically. This paper introduces two video quality assessment models. The first one requires the original video as a reference and is a structural distortion me ..."

The Structure of Wages and Investment in General Training
, 1997
"... This paper investigates the conditions under which firms are willing to invest in the general human capital of their workers. We show that a key ingredient is the presence of labor market imperfections which distort the wage structure. In particular, firms will invest in training if the gap between ..."

Staining of tissue sections for electron microscopy with heavy metals
, 1958
"... Heavy metals may be incorporated from solution into tissue sections for electron microscopy. The resulting increase in density of the tissue provides greatly enhanced contrast with minimal distortion. Relative densities of various structures are found to depend on the heavy metal ions present and on ..."
