Abstract

fetched live from OpenAlex

As microelectronic modules increase in power density, liquid cooling has become increasingly required to maintain acceptable chip temperatures. Liquid cooling in microchannels offers low thermal resistance and can be integrated into modules given their small size and implementation by microfabrication methods [1]. Microchannel cooling is therefore particularly well suited for embedded or portable applications. Their performance and compact form factor come, however, to the cost of increased pressure drop compared to larger scale cold plates. Since energy is limited in portable applications, power consumption by the cooling system (product of pressure drop and flow rate) should be minimized. This can be done by reducing the pressure drop with optimal design [2] or by distributing the flow in parallel microchannels or cell arrays [3], [4]. This work focuses on reducing the flow rate by adapting the pumping conditions to only provide the minimal flow rate required to maintain the maximum chip temperature.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
