This paper proposes a new approach to anonymous communication called information slicing. Typically, anonymiz-ers use onion routing, where a message is encrypted in layers with the public keys of the nodes along the path. Instead , our approach scrambles the message, divides it into pieces, and sends the pieces along disjoint paths. We show that information(More)
We describe the design of, and experience with, Query, a monitoring system that supports the Akamai EdgePlatform. Query is a foundation of Akamai's approach to administering its distributed computing platform, allowing administrators, operations staff, developers, customers, and automated systems near real-time access to data about activity in Akamai's(More)
The Akamai platform is a network of over 73,000 servers supporting numerous web infrastructure services including the distribution of static and dynamic HTTP content , delivery of live and on-demand streaming media, high-availability storage, accelerated web applications, and intelligent routing. The maintenance of such a network requires significant(More)

BACKGROUND Although some studies show higher antiretroviral concentrations in women compared to men, data are limited. We conducted a cross-sectional study of HIV-positive women to determine if protease inhibitor (PI) and non-nucleoside reverse transcriptase inhibitor (NNRTI) C(min) and Cmax values were significantly different than historical general(More)
BACKGROUND Direct-acting antivirals (DAAs) against hepatitis C virus (HCV) have been described as revolutionary. However, it remains uncertain how effective these drugs will be for individuals coinfected with human immunodeficiency virus (HIV)-HCV. Bridging this gap between efficacy and effectiveness requires a focus on the generalizability of clinical(More)
BACKGROUND Liver fibrosis progresses faster in individuals coinfected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV). Interferon λ3 (IFN-λ3) has both antiviral and proinflammatory properties. Genotypes at IFNL single-nucleotide proteins (SNPs; rs12979860CC and rs8099917TT) are linked to higher HCV clearance, potentially via rs8103142.(More)
BACKGROUND Liver diseases progress faster in human immunodeficiency virus (HIV)-hepatitis C virus (HCV)-coinfected persons than HIV-monoinfected persons. The aim of this study was to compare rates of liver fibrosis progression (measured by the aspartate-to-platelet ratio index [APRI]) among HIV-HCV-coinfected users of modern protease inhibitor (PI)- and(More)
