Of 682 antiretroviral-naïve patients initiating antiretroviral therapy in a prospective, multicenter human immunodeficiency virus type 1 (HIV-1) drug resistance monitoring study involving 8 sites in Hong Kong, Malaysia, and Thailand, the prevalence of patients with ≥1 drug resistance mutation was 13.8%. Primary HIV drug resistance is emerging after rapid scaling-up of antiretroviral therapy use...

This paper studies the stability of a network flow model with transmission and queuing delays in the forward and backward channels. We present a novel small gain approach to prove global asymptotic stability for arbitrary time delays and network routing. This approach uses a logarithmic state transformation suggested recently in the literature, and establishes a linear input-to-state gain for t...

Rectal swabs (feacal) samples were collected from 518 sheep across Sokoto state and processed for Campylobacter organisms. Of a total of 518 samples, 93(18.0%) yielded Campylobacter organisms. The Campylobacter species isolated in this study were Campylobacter jejuni, Campylobacter coli, Campylobacter lari and Campylobacter upsaliensis. The most frequently isolated Campylobacter species was C. ...

0031-9007= We report the direct excitation of the highly forbidden 6s2 S0 $ 6s6p P0 optical transition in two odd isotopes of neutral ytterbium. As the excitation laser frequency is scanned, absorption is detected by monitoring the depletion from an atomic cloud at 70 K in a magneto-optical trap. The measured frequency in 171Yb (F 1=2) is 518 295 836 591:6 4:4 kHz. The measured frequency in 173...
