1 Gondolo, PaoloClumpy neutralino dark matterWe investigate the possibility to detect neutralino dark matter in a scenario in which the galactic dark halo is clumpy. We find that under customary assumptions on various astrophysical parameters, the antiproton and continuum γ-ray signals from neutralino annihilation in the halo put the strong...Neutralinos; Clumpiness1999-01
2 Mishchenko, EugeneElectron-lattice kinetics of metals heated by ultrashort laser pulsesWe propose a kinetic model of transient nonequilibrium phenomena in metals exposed to ultrashort laser pulses when heated electrons affect the lattice through direct electron-phonon interaction. This model describes the destruction of a metal under intense laser pumping. We derive the system of equa...Electron-lattice kinetics; Thermoconductivity; electron temperature; Lattice deformation1999-01
3 Capecchi, Mario R.Paralogous mouse Hox genes, Hoxa9, Hoxb9, and Hoxd9, function together to control development of the mammary gland in response to pregnancy.Although the role of Hox genes in patterning the mammalian body plan has been studied extensively during embryonic and fetal development, relatively little is known concerning Hox gene function in adult animals. Analysis of mice with mutant Hoxa9, Hoxb9, and Hoxd9 genes shows that these paralogous g...Embryonic and Fetal Development; Gene Expression Regulation, Developmental; Genotype; Mice, Knockout1999-01
4 Liu, FengStep-induced optical anisotropy of vicinal Si(001)It is demonstrated, using reflectance difference spectroscopy, scanning tunneling microscopy, and low-energy electron diffraction, combined with deliberate straining of the surface, that the presence of atomic steps dramatically changes the optical anisotropy of the Si(001) surface. The step-induce...Step-induced; Optical anisotropy; Vicinal Si(001); Electron diffraction; Atomic steps1999-01
