A genetic algorithm assisted minimum mean-square error (MMSE) multi-user detector (MUD) is proposed for a turbo-trellis-coded modulation-based space division multiple access aided orthogonal frequency division multiplexing system. The simulation results show that the system employing the concatenated MMSE-GA MUD was capable of achieving a similar performance to that attained by its optimum coun...

Ultimate limits of an open pit, which define its size and shape at the end of the mine’s life, is the pit with the highest profit value. A number of algorithms such as floating or moving cone method, floating cone method II and the corrected forms of this method, the Korobov algorithm and the corrected form of this method, dynamic programming and the Lerchs and Grossmann algorithm based on grap...

Transportation costs are a significant part of capital and operating costs of large open pit mines. Cost efficiency and high reliability of in pit crushing and conveying systems compared to conventional truck-shovel system makes it more appealing to be utilized in modern mining activities. In this paper the suitable location of an in pit crusher is investigated as a single hub location problem....

OBJECTIVE The aim of this study was to reveal the efficacy of mud pack treatment in patients with knee osteoarthritis and to find the contribution of chemical factors to the build up of these effects. METHODS Sixty patients were randomly assigned to directly applied mud pack (study) group or to nylon-covered mud pack (control) group. Thirty patients in the study group had mud application 15 t...

In the MIMO-OFDM systems, the traditional methods of multi-user detection have some limitations in the rank-deficient scenarios, where the number of supported users exceeds the number of receiver antennas. The multiuser detection (MUD) based on the genetic simulated annealing algorithm (GSAA) is proposed for the rankdeficient problems in the multi-user MIMO-OFDM system. The simulation results s...

Hepatic pit cells are a population of large granular lymphocytes that substantially contribute to hepatic immunity. Studies have proven that pit cells have a role in liver regeneration, but the details of the relationship between pit cells and liver regeneration is not clear at present. We subjected rats to a two-third hepatectomy; pit cells with high purity were obtained with Percoll density c...

Pit-1 is a pituitary-specific transcription factor responsible for activating growth hormone (GH) and prolactin genes. Here, we describe the isolation of a rainbow trout cDNA clone that contains the entire Pit-1 coding region. The deduced amino acid sequence contains 358 residues, encoding a 39-kDa protein. Comparison of the protein sequences of the rainbow trout and rat Pit-1 shows that the 16...
