We have studied the genetic requirement for the normal expression of the terminal gap genes huckebein (hkb) and tailless (tll) and their possible function in the posterior pole region of the Drosophila embryo. At the early blastoderm stage, both genes are expressed in largely coextensive expression domains. Our results show that in the posterior region of the embryo both the activation and the ...

Nanocrystalline PbTe films are deposited on different substrates at room temperature through thermal evaporation. The films are stoichiometric single-phase polycrystalline with 200 texture. Electrical properties of the films are analyzed in the framework of a grain boundary channel conduction model. The index of refraction and extinction coefficient of PbTe films are extracted from infrared spe...

We illustrate the structure and dynamics of electron states in amorphous Si. The nature of the states near the gap at zero temperature is discussed and especially the way the structure of the states changes for energies ranging from midgap into either band tail (Anderson transition). We then study the effect of lattice vibrations on the eigenstates, and find that electronic states near the opti...

O ver the past 60 years, there have been substantial improvements in the college preparation of female students and the college gender gap has changed dramatically. Goldin, Katz, and Kuziemko (2006) show that female high school students now outperform male students in most subjects and in particular on verbal test scores. The ratio of male to female college graduates has not only decreased, but...

PURPOSE To map changes in the structure and function of fiber cell gap junctions that occur with lens differentiation. METHODS Equatorial lens sections were fluorescently labeled with antibodies to the gap junction protein connexin (Cx)46, the membrane marker wheat germ agglutinin, and the nuclear stain propidium iodide. Two-photon microscopy and digital image analysis were used to quantify l...

This paper investigates the role of domestic and global determinants core inflation in euro area. We analyse entire conditional distribution by estimating a Phillips curve type relationship with method expectile regression, here extended to capture time-varying effects. Both foreign output gap appear drive area inflation. Domestic has bigger influence right tail than left tail, providing eviden...
