Capillary-Operated Stable Mesoporous Optical System (COSMOS)
Bibliographic record
Abstract
We present the current research status of COSMOS (Capillary-Operated Stable Mesoporous Optical System) project, funded by DARPA (Defense Advanced Research Projects Agency) as part of the ZENITH program. The system features a unique non-rotating liquid mirror (LM) within a mesoporous structure containing ferrofluid and a thin metallic liquid layer. Capillary forces in the mesoporous structure shape a parabolic surface, and any residual shape departure are corrected by magnetic control from an electromagnetic coil array. The COSMOS system addresses a limitation of liquid mirrors by overcoming their inability to tilt, while also effectively mitigating the Rosensweig instability. In the current work, we present simulation results for ferrofluid displacement with and without porous media, utilizing MATLAB and COMSOL. The results demonstrate local control of the ferrofluid top surface at steady-state through the application of electromagnetic forces, along with the ability to regulate the surface profile during slewing with closed-loop control of a unit cell.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
