Analysing a set of preoperative and intraoperative variables associated with transfusions in patients undergoing isolated coronary artery bypass grafting (CABG), isolated valve, or combined procedures (CABG plus valve), we propose a simple model, which does not require computers, to estimate the need for PRBC of new cases in clinical practice.
The researchers used a combination of field surveys and computer models to estimate the density of animal numbers throughout the exclusion zone.
Yesterday, a team of scientists at the U.S. Geological Survey issued the most comprehensive study yet performed on the supervolcano, using sophisticated computer models to estimate the likelihood of another eruption and the devastation it would cause.
Having identified the combinations of the perforations on the tape and separately retained the service signals addressed directly to it, the computer proceeds to estimate the amount of the space occupied in a line by its letters and symbols, referring to instructions registered in its memory regarding each.
Despite the popularity of this "grandmother hypothesis", it has been hard to prove decisively, not least because among mammals the menopause seems to have evolved only in humans and some toothed whales.To study why this is so, Rufus Johnstone of the University of Cambridge used computer models to estimate the benefit of helping groupmates.
The researchers used computer models to estimate the health impacts of a range of outdoor air pollutants such as ozone and tiny particles less than 0.0025mm wide, which are known to cause cardiovascular problems and lung disease, said Jos Lelieveld of the Max Planck Institute for Chemistry in Mainz, Germany, who led the study published in the journal Nature.
It will also likely use technology to develop highly sophisticated computer modeling to estimate the total taxes we ought to pay.
Arctic experts at the University of Washington use temperature, satellite, and weather data in a computer model to estimate the total volume of ice in the area.
In their new study, the pair used thousands of computer simulations to estimate the cumulative effects of such close encounters on the lunar orbit.
By using computer simulations to estimate the velocity gradients in the flow field, it is shown that the proposed criterion is able to successfully predict the observed morphology.
