In a routine service delivery setting in Uganda, we assessed the ability of the WHO clinical stage to accurately identify HIV-infected patients in whom antiretroviral therapy should be started. Among 4302 subjects screened for ART, the sensitivity and specificity (95% CI) of WHO stage III, IV against a CD4 count < 200 x 106/l were 52% (50, 54%) and 68% (66, 70%) respectively. Plasma viral load ...

Raw slurry blending process is one of the key producing processes in the sintering alumina production. Key technical indices of this blending process are the quality indices of the raw slurry and the load state of the mill. Operation control objectives are to control the quality indices into their targeted ranges and control the load state of the mill in the good state. However, due to the diff...

Objective: To determine whether patients load the operated eg at a prescribed weight-bearing target load during postoprative recovery. Design: A descriptive prospective study. Setting: Orthopedic clinic and patients’ homes. Participants: Fifty patients who had undergone total hip rthroplasty (THA) with trochanteric osteotomy. Intervention: Patients were verbally instructed by a physial therapis...

Shared memory concurrency relies on synchronisation primitives: compare-and-swap, load-reserve/store-conditional (aka LL/SC), language-level mutexes, and so on. In a sequentially consistent setting , or even in the TSO setting of x86 and Sparc, these have well-understood semantics. But in the very relaxed settings of Power, ARM, or C/C++, it remains surprisingly unclear exactly what the program...

this paper proposes an optimal power flow (opf) algorithm by direct load control (dlc) programs to optimize the operational cost of smart grids considering various scenarios based on different constraints. the cost function includes active power production cost of available power sources and a novel flexible load curtailment cost associated with dlc programs. the load curtailment cost is based ...

In this paper we focus on the design of high performance peer-to-peer content sharing systems. In particular, our goal is to achieve global load balancing and short user-request response times. This is a formidable challenge, given the requirement to respect the autonomy of peers, their heterogeneity in terms of processing and storage capacities, their different content contributions, the huge ...

The paper validates the feasibility of automating the setting of common pilot power in a WCDMA radio network. The pilot automation improves operability of the network and it is implemented with a control software aiming for load and coverage balancing. The control applies measurements of base station total transmission power of neighboring cells and terminal reports of received pilot signal lev...

In this paper, we survey 82 papers related to revenue management and dynamic pricing of electricity and lists future research avenues in this field. Dynamic pricing has the potential to modify electric load profiles by charging different prices at different demand levels and hence can act as an effective demand side management tool. There are different forms of dynamic prices that can be offere...

Testing the performance of electricity markets using POWERWEB has already shown that relatively inexperienced players can identify and exploit market power in load pockets. When transmission constraints are not binding, however, auctions with six players have been shown to be efficient. There is evidence from operating electricity markets that prices can be driven above competitive levels when ...

It is recognized that iron overload is associated with excess mortality in HIV/AIDS, and that this may be due to iron acting as an HIV-1 transcriptional activator. In vitro evidence using iron chelators suggests that therapeutic iron depletion may be beneficial in HIV-1 infection. We describe the clinical course of a Caucasian man with hereditary haemochromatosis and HIV infection where a signi...
