We propose a blind interference alignment scheme for the vector broadcast channel where the transmitter is equipped with <i>M</i> antennas and there are <i>K</i> receivers, each equipped with a reconfigurable antenna capable of switching among <i>M</i> preset modes. Without any knowledge of the channel coefficient values at the transmitters and with only(More)
We show that the three-user M<sub>T</sub> &#x00D7; M<sub>R</sub> Multiple-Input Multiple-Output (MIMO) interference channel where each transmitter is equipped with M<sub>T</sub> antennas and each receiver is equipped with M<sub>R</sub> antennas has (M) d(M, N) =<sup>&#x0394;</sup> min (M/2-1/&#x03BA;, N/2+1/&#x03BA;) degrees of freedom (DoF) normalized by(More)
It has been conjectured that complex Gaussian interference channels with constant channel coefficients have only one degree-of-freedom (DoF) regardless of the number of users. While several examples are known of constant channels that achieve more than 1 DoF, these special cases only span a subset of measure zero. In other words, for almost all channel(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)
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)
We explore the degrees of freedom (DoF) of the K &gt;; 3 user M<sub>T</sub> &#x00D7; M<sub>R</sub> MIMO Gaussian interference channel where each transmitter is equipped with M<sub>T</sub> and each receiver is equipped with M<sub>R</sub> antennas. Expressing the DoF characterization as a function of the ratio &#x03B3; = M/N, where M = min(M<sub>T</sub>,(More)
Expression profile analysis clusters Gpnmb with known pigment genes, Tyrp1, Dct, and Si. During development, Gpnmb is expressed in a pattern similar to Mitf, Dct and Si with expression vastly reduced in Mitf mutant animals. Unlike Dct and Si, Gpnmb remains expressed in a discrete population of caudal melanoblasts in Sox10-deficient embryos. To understand(More)
