Abstract: A microfluidic device having an array for cell trapping is used to analyze cell-cell interaction at single-cell level. The microfluidic trapping array efficiently pairs single cells in isolated compartments in an easy-to-operate manner.

Abstract: Techniques are disclosed that relate to generating a rule for performing predictions of a characteristic of computer operations. A computer system may receive historical data that describes executed computer operations, including variables associated with those executed computer operations, and user input specifying desired properties of the performed predictions. The computer system determines, for a given variable, bins having ranges specified using the variable. The bins may be formed such that, when the executed computer operations are grouped into the bins, a prevalence of the characteristic monotonically increases or decreases from bin to bin across a bin ordering that is based on the ranges. The computer system then determines one or more cutoffs for one or more of the variables based on the desired properties from user's inputs and the determined bins. The computer system generates the rule based on the one or more cutoffs and the one or more variables.
