We design a differentiation-based multi-resolution approach for lossless image compression. The differentiation technique uses six appropriately weighted adjacent pixels (i.e., the pixels located at the west, west-west, north-west, north, north-east, and north-north of the predicted pixel) to estimate the predicted pixel intensity. This differentiation technique can also be considered as an add...

Populations of plant-parasitic nematodes in an Iowa cornfield were studied along north- and west-facing toposequences. Samples were collected monthly during the growing season. The greatest biomass for Xiphinema americanum occurred at the footslope on the north face. Paratylenchus microdorus had its greatest biomass at the summit position, generally more in the west- than in the north-facing sl...

Governments in south western Canada and the north west corner of US are now counting dead considering region’s ability to respond extreme temperatures after an unprecedented heat wave late June. The weather this part world is usually temperate. Warnings a massive “heat dome”1 started few days before thermometers began rise on 27 Meteorologists predicted near 38°C Seattle, Washington, 43°C Port...

We developed a loop-mediated isothermal amplification method that detects the JP2 clone of Aggregatibacter actinomycetemcomitans, which induces aggressive periodontitis in adolescents of North and West African descents. Being independent of special equipment, this specific and sensitive method offers significant advantages for screening of patients on a population basis and in clinical settings.
