Wireless Mobile Communications rely on a host of techniques, all related to one goal, sending the most possible information accross a link or a network. In recent years, both spatial and multiuser diversity have proven to be key techniques to achieve this goal. These two diversity dimensions can be exploited by the use of multiple antennas and/or the use of multiple terminals sending at the sam...

Numerous studies have demonstrated that the structural and functional differences between professional musicians and non-musicians are not only found within a single modality, but also with regard to multisensory integration. In this study we have combined psychophysical with neurophysiological measurements investigating the processing of non-musical, synchronous or various levels of asynchrono...

The nucleotide (nt) sequence of the 3' end of the yeast HIS3 mRNA was determined by PCR amplification of the 3' end. Analysis of 28 individual clones revealed that at least 13 distinct polyadenylation sites are present. The sites of polyadenylation are extremely heterogeneous and do not show any obvious similarity other than that they occur after pyrimidine residues in most cases. Most mutants ...

When people refer to objects linguistically, they must choose properties of the object that make it possible for the listener to identify the intended referent. We show that this selection of properties not only depends on the task environment but also changes over the course of time. We find that the salient feature color is used less often over time because of its limited utility in our task,...

Code/pulse-position-swapping (CPPS) is a communications scheme that substitutes pulse-position-modulation (PPM) symbols with optical-code-division-access (O-CDMA) codes. CPPS retains the multiple bits per symbol communication of M-ary PPM and the asynchronous multiple access of O-CDMA. Additionally, CPPS has the advantages of granular communications, common electrical bandwidth for all users in...

Y ou know you're a geek when going to the coffee shop gets you thinking about interaction patterns between loosely coupled systems. This happened to me on a recent trip to Japan. One of the more familiar sights in Tokyo is the numerous Starbucks coffee shops, especially around Shinjuku and Roppongi. While waiting for my " Hotto Cocoa, " I started thinking about how a coffee shop processes custo...

Helicobacter suis is a Gram-negative bacterium colonizing the majority of pigs, in which it causes gastritis and decreased daily weight gain. H. suis is also the most prevalent gastric non-Helicobacter pylori Helicobacter species in humans, capable of causing gastric disorders. To gain insight into the genetic diversity of porcine and human H. suis strains, a multilocus sequence typing (MLST) m...

The purpose of this study was to evaluate the profitability of hatchery litter recycling into poultry feedstuff supplement. The data were collected in 2011 in 4 provinces, by direct interviewing of all hatcheries which used the hatchery litter drying machine. Net Present Value (NPV), Benefit-Cost Ratio (BCR), and Internal Rate of Return (IRR) methods were applied for this analysis. In the studi...
