Memory dysfunction is a key symptom of age-related dementia. Although recent studies have suggested positive effects of electrical stimulation for memory enhancement, its potential targets remain largely unknown. In this study, we hypothesized that spatially targeted deep brain stimulation of ventromedial prefrontal cortex enhanced memory functions in a(More)

In July 2012, more than 30 years after the initial HIV case reports, the United States (US) Food and Drug Administration (FDA) approved the first drug for the prevention of sexually acquired HIV infection. On the basis of compelling safety and efficacy data from pre-exposure pro-phylaxis (PrEP) trials of men who have sex with men (MSM) conducted across four(More)
Pre-exposure prophylaxis (PrEP) for HIV prevention is a promising experimental approach currently being tested globally. A number of PrEP trials are evaluating the safety and effectiveness of PrEP in men who have sex with men (MSM) and other populations at risk for HIV, and results will be available from this first generation of efficacy trials over the(More)
This article presents a camera calibration system, Caliber, and the underlying pose estimation problem it solves, which we call sensor localization with rigidity (SL-R). SL-R is a constraint-satisfaction-like problem that finds a set of poses satisfying certain constraints. These constraints include not only relative pose constraints such as those found in(More)
For several years, the lectures in our introductory Electrical Engineering and Computer Science (EECS) courses have been videotaped and webcast, mainly as an aid to students with time conflicts that prevent them from attending class. We present the Weiner Lecture Archives - a project to identify, archive, filter, and make available the best of these(More)
OBJECTIVE The efficacy of pre-exposure prophylaxis (PrEP) in HIV will diminish with poor adherence; pharmacologic measures of drug exposure have proven critical to PrEP trial interpretation. We assessed drug exposure in hair against other pharmacologic and more routinely used measures to assess pill-taking. DESIGN Participants were randomized to placebo,(More)
INTRODUCTION After the initial approval of the use of tenofovir disoproxil fumarate-emtricitabine (TDF/FTC) by the US Food and Drug Administration in 2012 for anti-HIV pre-exposure prophylaxis (PrEP), uptake was initially limited, but more recent community surveys and expert opinion suggest wider acceptance in some key populations. DISCUSSION(More)
There has been a recent shift in design paradigms, with many turning towards yield-driven approaches to synthesize and design systems. A major cause of this shift is the continual scaling of transistors, making process variation impossible to ignore. Better than worst-case (BTW) designs also exploit these variation effects, while also addressing performance(More)
In 2009, the National Institutes of Health recognized the need to expand knowledge of lesbian, gay, bisexual, and transgender (LGBT) health and commissioned the Institute of Medicine to report on the health of these populations in the United States. The resulting Institute of Medicine publication called for more knowledge of the health of LGBT populations,(More)
