This paper proposes an index for nodal market power detection in power market under locational marginal pricing (LMP). This index is an ex-ante technique to detect the market power. More precisely, this criterion detects the potential of exercising market power regardless of detecting the actual market power. Also it is obvious that pricing and market clearing method affect the potential of exe...

Load balancing emerges as an important problem that affects the performance of structured peer-to-peer systems. This paper presents a peer-to-peer system relying on the partitionning of a de Bruijn graph. The proposed system integrates mechanisms that perform index and storage load balancing. Index load refers to the network traffic incurred by a peer in managing an object index, while storage ...

The diagnosis of primary HIV-1 infection (PHI) is often missed and requires a high index of suspicion and a thorough knowledge of laboratory methods. We report the case of a young promiscuous male who presented with fever, rash and neurological symptoms 8 weeks after unprotected sexual exposure. Clinical and laboratory investigations showed the presence of leucopenia and thrombocytopenia with e...

BACKGROUND Dietary glycemic index (GI) and glycemic load (GL) have been related to the risk of selected cancers, but the issue remains open. PATIENTS AND METHODS Mailed questionnaires were completed between 1994 and 1997 in eight Canadian provinces for incident, histologically confirmed cases of the stomach (n=1182), colon (n=1727), rectum (n=1447), liver (n=309), pancreas (n=628), lung (n=33...

the concentration of selected trace metals (fe, cd, cu, pb, and zn) in 30surface sediments were measured using atomic absorption spectrometer to investigatethe spatial and seasonal variations of trace metals along kanyakumari coast, india. toassess the environmental risk of trace metals, enrichment factor, geo-accumulation index,pollution load index, and ecological risk index have been calculat...

Background. This study tested whether the simple ratio of ventricular end-systolic pressure to stroke volume, known as the effective arterial elastance (Ea), provides a valid measure of arterial load in humans with normal and aged hypertensive vasculatures. Methods and Results. Ventricular pressure-volume and invasive aortic pressure and flow were simultaneously determined in 10 subjects (four ...

Designing appropriate materials and activities to enhance vocabulary learning is one of the primary goals of language courses. Among the claims about efficient pedagogical tasks is the Involvement Load Hypothesis (Laufer & Hulstijn, 2001) according to which vocabulary development is contingent on the amount of cognitive process a task involves. Building on the previous research on this hypothes...
