A network should deploy QoS-aware path selection algorithms for efficient routing. To this end, measurements of the various characteristics of the network can provide insight into the state and performance of the network. In this paper, we present a new QoS-aware path selection algorithm for flows requiring bandwidth guarantees based on an estimation… (More)
In a multi-service network, different applications have varying QoS requirements. The IETF has proposed the DiffServ architecture as a scalable solution to provide Quality of Service (QoS) in IP Networks. In order to provide quantitative guarantees and optimization of transmission resources, DiffServ mechanisms should be complemented with efficient traffic… (More)
Studies of tie formation in social networks point to the salience and seeming ubiquity of several generative micro-level mechanisms: homophily, balance, and status (Gould 2002; Heider 1946; McPherson, Smith-Lovin, and Cook 2001). The story differs, however, when we focus our analytic lens on the structure of the entire network. The image of similarity in… (More)
We compare the performance of multiple respondent-driven sampling estimators under different sample recruitment conditions in hidden populations of female sex workers in the midst of China's ongoing epidemic of sexually transmitted infections. We first examine empirically calibrated simulations grounded in survey data to evaluate the relative performance of… (More)

Unilateral and bilateral lower-body heavy resistance exercises (HREs) are used for strength training. Little research has examined whether muscle activation and testosterone (TES) responses differ between these exercises. Our purpose was to compare the effects of unilateral and bilateral lower-body HRE on muscle activity using surface electromyography… (More)
