BACKGROUND The optimal treatment of malaria in human immunodeficiency virus (HIV)-infected children requires consideration of critical drug-drug interactions in coinfected children, as these may significantly impact drug exposure and clinical outcomes. METHODS We conducted an intensive and sparse pharmacokinetic/pharmacodynamic study in Uganda of the most(More)
—In cognitive radio networks (CRNs), dynamic spectrum access has been demonstrated as an effective way to improve the spectrum utilization. Spectrum holes can be exploited not only in certain time slots or frequency bands, but also at particular locations. In relay assisted CRNs, one relay at a certain location can help to identify and provide different(More)
OBJECTIVE The childhood obesity epidemic has been accompanied by an increasing prevalence of type 2 diabetes (T2D), particularly in minority children. Twenty to thirty percent of obese youth have "prediabetes," a precursor to diabetes marked by insulin resistance, β-cell dysfunction, and impaired glucose tolerance. The Diabetes Prevention Program(More)
BACKGROUND Preterm (PT) children show early cognitive and language deficits and display altered cortical connectivity for language compared to term (T) children. Developmentally, functional connectivity networks become more segregated and integrated, through the weakening of short-range and strengthening of long-range connections. METHODS Longitudinal(More)
BACKGROUND Artemisinins are primarily responsible for initial parasite clearance. Antimalarial pharmacokinetics (PK), human immunodeficiency virus (HIV) infection, and antiretroviral therapy have been shown to impact treatment outcomes, although their impact on early parasite clearance in children has not been well characterized. METHODS Parasite(More)
Cognitive radio can improve the spectrum efficiency by allowing multiple secondary users to access the idle licensed spectrum, for which efficient and fair spectrum sharing is one of the key challenges. In this paper, we investigate the multiuser multi-channel spectrum allocation problem in cognitive radio networks with the objective of maximizing the(More)
BACKGROUND Early intervention services for psychotic disorders optimally interlock strategies to deliver: (i) Early Detection (ED) to shorten the time between onset of psychotic symptoms and effective treatment (i.e. Duration of Untreated Psychosis, DUP); and (ii) comprehensive intervention during the subsequent 2 to 5 years. In the latter category, are(More)
