Using our novel proposed technology, we combine the advantages provided by the clinical standard tool of flow cytometry in quantifying single cells and also retain the advantages of microscopy in retaining the capability of visualizing the immunoreactive cells. Unlike flow cytometry however, the invention uses commonly available formalin fixed immunostained tissue and not fresh viable cells. To accomplish this aim, we resort to new and improved advanced image analysis using a unique, useful, and adaptive process as described herein. The method uses multi-stage thresholding and segmentation algorithm based on multiple color channels in RGB and HS I spaces and uses auto-thresholding on red and blue channels in RGB to get the raw working image of all cells, then refines the working image with thresholding on hue and intensity channels in HS I using an adaptive parameter epsilon in entropy mode, and further separates different groups of cells within the same class, by auto-thresholding within the working image region. The Immunohistochemistry Flow cytometry (IHCFLOW) combination results in a new paradigm that is both useful, novel, and provides objective tangible result from a complex color image of tissue.

A method and computer program for efficient cell failure rate estimation in cell arrays provides an efficient mechanism for raising the performance of memory arrays beyond present levels / yields. An initial search is performed across cell circuit parameters to determine failures with respect to a set of performance variables. For a single failure region the initial search can be a uniform sampling of the parameter space and when enough failure points have been accumulated, a mean is chosen from the mean of the detected failure points. Mixture importance sampling (MIS) is then performed to efficiently estimate the single failure region. For multiple failure regions, a particular failure region is selected by varying the memory circuit cell parameters along a random set of vectors until failures are detected, thus identifying the boundary of the failure region of interest as the closest failure region. A new mean is chosen for MIS in conformity with the location of the detected boundary.
