BACKGROUND The natural history of HIV infection has changed dramatically after the introduction of highly active antiretroviral therapy. Currently, opportunistic illnesses still represent a major cause of death and hospitalization in this population. In this study, we review the trends in opportunistic illnesses incidence rates and compare the results observed in high-income settings with that ...

While mixed reality has inspired the development of many new musical instruments, few approaches explore the potential of mobile setups. We present a new musical interaction concept, called opportunistic music. It allows musicians to recreate a hardware musical controller using any objects of their immediate environment. This approach benefits from the physical attributes of real objects for co...

Grids are becoming mission-critical components in research and industry, offering sophisticated solutions in leveraging largescale computing and storage resources. Grid resources are usually shared among multiple organizations in an opportunistic manner. However, an opportunistic or “best effort” quality-of-service scheme may be inadequate in situations where a large number of resources need to...

The increasing trend on wireless-connected devices makes opportunistic networking a promising alternative to existing infrastructure-based networks. However, on these networks there is neither guarantee about the availability of the connections nor on the topology of the network. The development of opportunistic applications, i.e., applications running over opportunistic networks, is still in e...

In this paper, we present a model of oppor-tunistic planning that uses planning-time rear soning about the opportunities that might arise during plan execution. The model is composed of three parts: a planning-time mechanism that places blocked goals into memory for later activation, an understanding system that activates suspended goals as a by-product of parsing the world, and an execution-ti...
