OBJECTIVES To assess the temporal trends in incidence of AIDS-defining opportunistic illnesses in an urban cohort of a middle-income country. METHODS HIV infected patients aged ≥ 18 years at cohort entry were included in this analysis. We calculated incidence rates per 1000 persons-years of observation for the first opportunistic illness presented after cohort enrollment, from 1987 to 2012. T...

Opportunistic infections continue to be a major cause of disease in patients with HIV infection. Despite the development of highly active antiretroviral therapy (HAART ) , opportunistic infections continue to be seen in patients who do not have access to antiretrovirals, and in patients who do not have an adequate response to antiretrovirals [1]. Viral infections are a major cause of opportunis...

Opportunistic networks are used in the remote, disaster prone areas where there is no network between the users and to create a network without any relation between nodes. In this paper we are creating a trust scenario for Opportunistic networks that is based on the methods of localization. We are proposing a model to overcome issues regarding opportunistic network nodes mobility, storage and s...

This paper proposes an opportunistic maintenance policy for the multi-unit series production system. This proposed maintenance policy is on the basis of the failure rate analysis, which is more realistic than age-based or time-based opportunistic replacement models. When a system halts for performing preventive maintenance or opportunistic maintenance, the alternative decision of replacement an...

Researchers commonly explore their data in multiple ways before deciding which analyses they will include in the final versions of their papers. While this improves the chances of researchers finding publishable results, it introduces an "opportunistic bias," such that the reported relations are stronger or otherwise more supportive of the researcher's theories than they would be without the ex...

Bottleneck-centered, opportunistic scheduling is an effective problem solving paradigm based on a fundamental Analyze-Focus-Decide cycle. Opportunistic schedulers have shown better overall performance than other scheduling systems adopting different paradigms. However. in order to make more significant progress, we need to better understand how the different phases of the opportunistic cycle in...

BACKGROUND Systematic screening for precancerous cervical lesions has resulted in decreased incidence and mortality of cervical cancer. However, even in systematic screening programs, many women are still tested opportunistically. This study aimed to determine the spread of opportunistic testing in a systematic cervical cancer screening program, the impact of opportunistic testing in terms of d...

This deliverable describes different test-beds for the validation of the architecture, algorithms and protocols for the operator governed opportunistic networking as defined in the OneFIT Project. Further on, this deliverable provides a description of the implementation of the OneFIT cognitive management systems CSCI and CMON as well as the C4MS protocol. Also, implementation of the blocks supp...

This paper introduces a new game-theoretic framework and algorithms for addressing opportunistic crime. The Stackelberg Security Game (SSG), which models highly strategic and resourceful adversaries, has become an important computational framework within multiagent systems. Unfortunately, SSG is ill-suited as a framework for handling opportunistic crimes, which are committed by criminals who ar...

Ferry-based networks provide a means of bringing extremely low-cost Internet access to remote rural areas, where conventional access technologies, e.g., dial-up, DSL and CDMA, are currently economically infeasible. We present an architecture for ferry-based networks and identify downlink scheduling as a difficult open problem. We argue that opportunistic scheduling policies that take ferry sche...
