A broad spectrum of techniques for electrocardiogram (ECG) data compression have been proposed during the last three decades. Such techniques have been vital in reducing the digital ECG data volume for storage and transmission. These techniques are essential to a wide variety of applications ranging from diagnostic to ambulatory ECG's. Due to the diverse(More)
It is not possible to compare the result of the previously mentioned heuristics with all possible CHT assignments, because, in our case, M is 511 and a reasonable value for m could be 8 so that about 10 17 diierent possible combinations should be considered. Therefore, we do not actually know how far our solution is from the optimal one. Nevertheless , some(More)
HYPOTHESIS There is a potential for margin distortion associated with the use of a compression plate in specimen mammography (SM) devices. DESIGN Prospective observational study. SETTING Two tertiary care teaching hospitals. PATIENTS Breast biopsy tissue dimensions were recorded in 15 patients undergoing 18 operations before and after SM (group 1).(More)
The data from several types of bioassays is usually presented as a quotient as an intuitive parameter and a means of comparing results between experiments. For the example we considered here, we look at experiments with an experiment-wide negative control used to generate percent activity quotients from each experimental group. We asked if there was a valid(More)
