In the recent years, the demand for higher data rates has been continuously growing to satisfy consumers’ desire for a faster, safer, and smarter wireless network. Since current wireless systems are facing a bottleneck in spectrum resources which make it difficult to enhance performance in the limited available bandwidth. To overcome this problem new Generation of mobile communication known as ...

The 5 g. d-xylose absorption test has been studied in 50 normal subjects. The five-hour urinary xylose content was 1.75 +/- 0.43 g. Xylose absorption was more rapid and more complete with the 5 g. than with the 25 g. test. Comparative studies showed the results of the two tests to be significantly related, but the 5 g. test was a less sensitive indicator of malabsorption than the 25 g. test. Th...

In this paper we establish under suitable conditions the existence of measurable selectors for Gs-valued multifunctions. In particular we prove that a measurable partition of a Polish space into G6 sets admits a Borel selector.
