Evidence from autoimmune thyroiditis of skewed X-chromosome inactivation in female predisposition to autoimmunity
(Nature Publishing Group, 2006)
The etiologic factors in the development of autoimmune thyroid diseases (AITDs) are not fully understood. We investigated the role of skewed X-chromosome inactivation (XCI) mosaicism in female predisposition to AITDs. One ...
Bases in the spaces of C∞-functions on Cantor-type sets
(Springer New York LLC, 2006)
We construct a topological basis in the space of Whitney functions given on the Cantor-type set.
Reprogramming of replicative senescence in hepatocellular carcinoma-derived cells
(National Academy of Sciences, 2006)
Tumor cells have the capacity to proliferate indefinitely that is qualified as replicative immortality. This ability contrasts with the intrinsic control of the number of cell divisions in human somatic tissues by a mechanism ...
On the stability of Fröhlich bipolarons in spherical quantum dots
(Institute of Physics, 2002)
In the strong-electron-phonon-coupling regime, we retrieve the stability criterion for bipolaron formation in a spherical quantum dot. The model that we use consists of a pair of electrons immersed in a reservoir of bulk ...
Transmission properties of composite metamaterials in free space
(American Institute of Physics, 2002)
We propose and demonstrate a type of composite metamaterial which is constructed by combining thin copper wires and split ring resonators (SRRs) on the same board. The transmission measurements performed in free space ...
Formation of alkylsilane-based monolayers on gold
(American Chemical Society, 2002)
The formation of monolayers of alkylsilanes on a gold surface is characterized by X-ray photoelectron and reflection-absorption infrared spectroscopies. The reaction occurs through the activation of multiple Si-H bonds. ...
Anharmonicity of zone-center optical phonons: Raman scattering spectra of GaSe0.5S0.5 layered crystal
The temperature dependencies (10-300 K) of the eight Raman-active mode frequencies and linewidths in GaSe0.5S0.5 layered crystal have been measured in the frequency range from 10 to 320 cm-1. We observed softening and ...
Effects of hue, saturation, and brightness on preference
A study was done to investigate preference responses for foreground-background color relationships. To do this, 123 university undergraduates in Ankara, Turkey, were asked to view eight background colors selected from HSB ...
On the Lévy-Raikov-Marcinkiewicz theorem
Let μ be a finite nonnegative Borel measure. The classical Lévy-Raikov-Marcinkiewicz theorem states that if its Fourier transform ̂m can be analytically continued to some complex half-neighborhood of the origin containing ...
Filtering characteristics of hybrid integrated polymer and compound semiconductor waveguides
This paper reports a study on a compact filter fabricated using hybrid integration of compound semiconductors and polymers. A GaAs epilayer is glued onto a polymer channel waveguide forming a highly asymmetrical directional ...
