A low power, highly efficient, linear, enhanced wideband Class-J mode power amplifier for 5G applications.

In wireless communication networks, the necessity for high-speed data rates has increased in emerging 5G application areas. The Power Amplifier (PA) topologies reported to date achieved desired Power Added Efficiency (PAE) and linearity. However, these harmonically tuned switching PAs are less appealing for broadband applications as they are restricted to narrow bandwidth (BW).

Empirical treatment for pediatric urinary tract infection and resistance patterns of uropathogens, in Queen Alia hospital and prince A'Isha military center--Jordan.

We conducted this retrospective study to identify the most appropriate oral antibiotic as empiric treatment of urinary tract infection according to resistance patterns of uropathogens among children treated at Queen Alia Military Hospital and Prince Aisha Bent Al-Hussein Military Center from January 2006 to April 2007. Urine cultures for isolated microorganism and their anti-biotic susceptibility in patients below the age of 14 years treated as outpatient were reviewed. Out of 3820 cultures, 529 isolates were found, E coli was the most frequent organism.
