Y-chromosomal diversity in Europe is clinal and influenced primarily by geography, rather than by language
(American Journal of Human Genetics, 2000)
Clinal patterns of autosomal genetic diversity within Europe have been interpreted in previous studies in terms of a Neolithic demic diffusion model for the spread of agriculture; in contrast, studies using mtDNA have ...
Origin of charge-orbital order in the half-doped manganites
(Physical Review Letters, 2002)
The microscopic origin of the charge and orbital order in the half-doped manganites is examined from ab initio density-functional calculations and exact diagonalization studies. It is shown that the dominant mechanism ...
Novel mechanism of steroid action in skin through glucocorticoid receptor monomers
(Molecular and Cellular Biology, 2000)
Glucocorticoids (GCs), important regulators of epidermal growth, differentiation, and homeostasis, are used extensively in the treatment of skin diseases. Using keratin gene expression as a paradigm of epidermal physiology ...
Electronic structure and exchange interaction in the layered perovskite Sr3Mn2O7
(Physical Review B: Condensed Matter and Materials Physics, 2002)
The electronic structure of the Ruddlesden-Popper layered perovskite compound Sr3Mn2O7 is studied from density-functional calculations using the linear muffin-tin orbitals method. An antiferromagnetic, insulating solution ...
Experimental and theoretical study of lattice relaxation around refractory atoms in nickel
(Acta Materialia, 2008)
The lattice relaxation around Mo, Ru, Hf, Ta, W and Re in Ni is investigated by means of X-ray absorption spectroscopy. For all of the investigated concentrations the substitutional lattice position is confirmed except for ...
Negative response elements in keratin genes mediate transcriptional repression and the cross-talk among nuclear receptors
(Journal of Biological Chemistry, 2001)
Very little is known about the mechanisms responsible for the findings that binding of nuclear receptors (NR) to some promoter elements leads to transcriptional activation, whereas binding to others leads to repression. ...
Persistent homology of complex networks
(Journal of Statistical Mechanics: Theory and Experiment, 2009)
Long-lived topological features are distinguished from short-lived ones (considered as topological noise) in simplicial complexes constructed from complex networks. A new topological invariant, persistent homology, is ...
Measurement of diffractive scattering of photons with large momentum transfer at HERA
(Physics Letters B, 2009)
The first measurement of diffractive scattering of quasi-real photons with large momentum transfer gamma p - GT gamma Y, where Y is the proton dissociative system, is made using the H1 detector at HERA. The measurement is ...
Charge stacking in the half-doped manganites
(Journal of Applied Physics, 2002)
The stability of the charge-stacked structure vis-a-vis the charge-alternate structure in the half-doped manganites is studied with a model that includes electronic kinetic energy, onsite and intersite Coulomb interactions, ...
Disparities in rheumatoid arthritis disease activity according to gross domestic product in 25 countries in the QUEST-RA database
(Annals of the Rheumatic Diseases, 2009)
Objective: To analyse associations between the clinical status of patients with rheumatoid arthritis ( RA) and the gross domestic product (GDP) of their resident country. Methods: The Quantitative Standard Monitoring of ...
