Detailed droplet routing and complexity characterization on a digital microfluidic biochip
Bibliographic record
Abstract
Digital microfluidic systems (DMFS) are poised to provide fully automated, high-throughput, dynamically reconfigurable sensing devices superior to those available today. Efficient droplet routing algorithms for these systems have not yet been established, though several solutions have been proposed. Such algorithms are ultimately required to generate droplet movement schedules and must be robust enough to handle the inevitable increases in problem complexity that will come as this technology matures. We have proposed a new solution based on a classic VLSI lineprobe algorithm to meet these demands for the detailed routing of droplets within a multi-stage algorithm. The most significant addition includes a sub-algorithm that calculates the routing complexity for any DMFS configuration based on the size, shape, number, type, and distribution of rectilinear obstacles throughout a DMFS biochip surface. By determining the complexity of the routing of each droplet, routing schedules may be prioritized, minimizing the number of fluidic and time constraint violations that affect high priority droplet routes. The complexity characterizations generated by our algorithm may also be used to create consistent, standardized benchmarks for the evaluation of existing droplet routing solutions. The efficiency of the proposed algorithm has been verified using the simulation presented in this paper.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
