This is achieved by applying QL decomposition followed by elementary matrix operations on H in a manner analogous to the modified QL decomposition algorithm based on the Gram-Schmidt orthogonalization procedure, thus avoiding the need for expensive matrix inversion operations.
The learning rate represents the convergence speed and the momentum parameter introduces a damping effect on the search procedure, thus avoiding oscillations in irregular areas of the error surface by averaging gradient components with opposite signs and accelerating the convergence in long flat areas.
Recruitment activities, biospecimen collection, and body size measurements occurred prior to the prostate biopsy procedure, thus avoiding biases associated with treatment or knowledge of their disease status.
Before fitting a circular two-dimensional Gaussian function to each ROI intensity map, an empirical parameter of 1/2 was chosen as the fraction of (highest gray value) ROI pixels to be fed into the fitting procedure thus avoiding the bias induced by residual fluorescence of adjacent structures (e.g., defocused adjacent kinetochores).
It was therefore attempted to correlate ageing, or the age, of the cellulosic samples with age-linked parameters that could be measured experimentally, if possible using relatively simple procedures and thus avoiding expensive apparatus [5 7].
When a positive sample is collected, the procedure can be abandoned, thus avoiding unnecessary multiple punctures of lymph nodes.
A significant advantage of these neonatal tissues is their ready availability, thus avoiding invasive procedures and ethical problems.
All data entered in the forms is submitted to online validation procedures before entering the database, thus avoiding some of the most common user errors that may cause integrity or consistency violations in the database.
These procedures appeared efficient and mild, thus avoiding denaturation of protein, and resulted in optimal quality conjugates at an overall radiochemical yield of 55 70% (not corrected for decay).
A complementary molecular imaging technique allows for better characterisation of incidental findings from screening procedures, such as solitary lung nodules, dense breast lesions and suspected prostate cancer, thus avoiding unnecessary invasive procedures and biopsies in patients with negative molecular scans [21].
