Therefore the spatial filtering step in the digital phase retrieval algorithm must be tailored for each acquired interferogram based on previous system characterization.
The condition used for this study applied a dosage of Fe(II) of 6.9 mg/L, with an initial pH of 3 and an electrical current of 40 mA based on previous system optimization.
The classification system is based on previous classification systems and on a review of all the primary ovarian tumors from the archives of the National Cancer Institute (NCI) and NTP Carcinogenesis Testing Programs.
Cost calculations were based on previous surveillance system experience and included one training for five hospital staff (2 doctors, 1 nurse, 1 laboratory worker and 1 medical records staff), four monitoring visits to the site, six-monthly national meetings and costs for stationery and staff incentives.
Based on previous experience in system tuning [27, 28], system gain and time constant for all underlying linear models were fixed for all four filters.
The strategies are based on previous research into system identification using multiple models.
The threshold is based on previous work in pastoral systems in the area that indicates this is a threshold for mobility in pastoral systems (Fratkin and Roth 1990); 82% of observations are below this threshold.
Since this model is based on previous studies on inducible systems, we first analysed its ability to reproduce the available experimental observations for that class of systems.
Based on previous studies in sensory systems, two alternative neural mechanisms, multiplicative increase in neural gain [1] [16] vs. enhanced feature selectivity of the neurons in sensory cortices [17] [21], have been suggested to underlie selective attention.
Based on previous analyses of TA systems in Escherichia coli K12 [ 4], Mycobacterium tuberculosis[ 17] and Mycobacterium smegmatis[ 18], we speculated that acquired-TA systems might play a positive role in survival of Sz35246 under different host environments.
