Microscopy images from different imaging conditions, organs, and tissues often have numerous cells with various shapes on a range of backgrounds. As result, designing deep learning model to count in source domain becomes precarious when transferring them new target domain. To address this issue, manual annotation costs are typically the norm training learning-based cell counting models across d...

fungicidal efficiency of iranian made benzalkonium chloride named akhgar, afshang and hamoon were evaluated on pure culture species of aspergillus nijer, candida ablicans and mucour according to the standard method no. 2442 issued by the institute of standards and industrial research of iran, from october 1993 to march 1994. suspensions were prepared in a way that each cubic centimeter having 3...

Because of the change in path-length of the alpha particle as a function of air density, it has long been suspected that scintillation cells would have different counting efficiencies at different air densities (elevations), where counting efficiency is here defined as that fraction of radiation produced within the cell that is actually counted. However, except for a few isolated examples (Geor...

An instrument for the continuous recording of cell number has been developed and is being used to record changes in populations of logarithmic and synchronized cultures of protozoan flagellates. A Coulter cell counter is used in conjunction with a counting chamber that is fitted with a flexible polyethylene aperture (75 micro in diameter). This aperture rarely becomes blocked and appears to be ...

Fluorescence in situ hybridization allows the enumeration of chromosomal abnormalities in interphase cell nuclei. This process is called dot counting. To estimate the distribution of chromosomes per cell, a large number of cells have to be analysed, particularly when the frequency of aberrant cells is low. Automation of dot counting is desirable because manual counting is tedious, fatiguing, an...

Manually counting cell colonies, especially those that originate from fibroblast cell lines, is a time-consuming, eye-straining and tedious task in which consistency of counting is difficult to maintain. In this paper we present a novel model-based image segmentation method, which employs prior knowledge about the shape of a colony with the aim to automatically detect isolated, touching and ove...
