We propose a blind interference alignment scheme for the vector broadcast channel where the transmitter is equipped with M antennas and there are K receivers, each equipped with a reconfigurable antenna capable of switching among M preset modes. Without any knowledge of the channel coefficient values at the transmitters and with only mild assumptions on the(More)
We show that the 3-user M T × M R MIMO interference channel where each transmitter is equipped with M T antennas and each receiver is equipped with M R antennas has d(M, N) = min M 2−1/κ , N 2+1/κ degrees of freedom (DoF) normalized by time, frequency, and space dimensions , where M = M N −M. While the DoF outer bound of d(M, N) is established for every M T(More)
It has been conjectured by Høst-Madsen and Nosratinia that complex Gaussian interference channels with constant channel coefficients have only one degree-of-freedom regardless of the number of users. While several examples are known of constant channels that achieve more than 1 degree of freedom, these special cases only span a subset of measure zero. In(More)
BACKGROUND We present the genome sequence of the tammar wallaby, Macropus eugenii, which is a member of the kangaroo family and the first representative of the iconic hopping mammals that symbolize Australia to be sequenced. The tammar has many unusual biological characteristics, including the longest period of embryonic diapause of any mammal, extremely(More)
— We provide innerbound and outerbound for the total number of degrees of freedom of the K user multiple input multiple output (MIMO) Gaussian interference channel with M antennas at each transmitter and N antennas at each receiver if the channel coefficients are time-varying and drawn from a continuous distribution. The bounds are tight when the ratio
The increasing number of assembled mammalian genomes makes it possible to compare genome organisation across mammalian lineages and reconstruct chromosomes of the ancestral marsupial and therian (marsupial and eutherian) mammals. However, the reconstruction of ancestral genomes requires genome assemblies to be anchored to chromosomes. The recently sequenced(More)
PURPOSE To understand the mechanisms mediating retinal ganglion cell loss in glaucoma, the gene expression patterns were compared for transferrin, ceruloplasmin, and ferritin between normal and glaucomatous retina in monkey and human eyes. METHODS Laser photocoagulation was used to produce unilateral experimental glaucoma in monkeys. Gene expression was(More)
PURPOSE One approach to gaining insight into the biological pathways contributing to rod and cone photoreceptor death is to identify patterns of gene expression changes. In the present study, a custom retinal microarray was developed to analyze the rd1 mouse, a well-characterized animal model of human retinal degeneration. METHODS A microarray was(More)
