Crystals with the cubic fluorite structure and small lattice mismatches can be grown epitaxially on cubic semiconductors.
We consider the downlink of a multi-cell system where base stations and users are equipped with multiple antennas.
In this paper we investigate and enhance the user-pairing probability in a system employing multi-user superposition transmission (MUST).
This paper formulates the power allocation policy that maximizes the region of ergodic mutual informations achievable in multiuser downlink OFDM channels known only statistically by the base statio
Spin dynamics at the planar Cu(2) sites in oxygen deficient YBa sub 2 Cu sub 3 O sub (6+x) have been investigated by sup (63,65) Cu nuclear quadrupole resonance and spin- lattice relaxation measure
We have used x-ray photoemission spectroscopy to study the core level spectra of 200angstroms Bi-Sr-Ca-Cu oxide thin films, in the hope the importance of the surface sensitivity of photoemission
We present Raman and infrared absorption data for Ba sub 2 YCu sub 3 O sub x with 7 > x > 6 for several samples with well characterized oxygen content.
Elastic and inelastic atomic helium scattering has been used to characterize the Cu:Si(111) "quasi-5x5" surface.
Since multiple scattering effects are absent in helium Diffraction, we can verify that the 'quasi-5x5' structure of Cu:Si(111) seen with LEED is actually an incommensurate reconstruction with a uni
The SACRED project is a nano-satellite designed by students to study the radiation effects on electronic devices in flight.
