Objectives To compare long-term adherence to antiretroviral therapy in an HIV service, as measured by self-report and by pharmacy records. To determine the level of adherence by each measure required to suppress viral load in a majority of patients. Methods The percentage of prescribed doses taken

by successfully managing geothermal fields in the long term are crucial to the future of geothermal. Over a relatively long term (100 years and beyond), these strategies may involve cycles of utilization to allow recovery of depleted reserves from deeper recharge zones. To achieve continuous geothermal generation

By conceptualizing digital workflows that enable the utilization of 3D city models and the integration of planning proposals by multiple stakeholders, it will be shown how the collaborative use of official 3D city models can support

A two-process theory of human information processing is proposed and applied to detection, search, and attention phenomena. Automatic processing is activa-tion of a learned sequence of elements in long-term memory that is initiated by appropriate inputs and then proceeds automatically

. We approach this question from the perspective of horizon effects: Given the evidence of predictability in returns, should a long-horizon investor allocate his wealth differently from a short-horizon investor? The motivation for thinking about the problem in these terms is the classic work

retrieval model to text retrieval model, such that the well established textretrieval techniques can be utilized. Approaches of converting image feature vectors (IP domain) to weighted-term vectors (IR domain) are proposed in this paper. Furthermore, the relevance feedback technique fromthe

MURDOCH in two very different domains: a tightly coupled multirobot physical manipulation task and a loosely coupled multirobot experiment in long-term autonomy. The primary contribution of this paper is to show empirically that distributed negotiation mechanisms such as MURDOCH are viable and effective
