Thermodynamic Approach to Cerebrospinal Fluid Circulation
Bibliographic record
Abstract
Background : The authors present the thermodynamic approach to the cerebrospinal fluid circulation. Methods : On the basis of skin temperature measurements in 16 healthy volunteers a 1.6 ± 0.2 oC (mean ± SD) difference between the frontal and the lumbar regions has been showed. Results : Such a temperature difference between both ends of the subarachnoid space in the intracranial and the intracanal compartments can cause natural circulation of cerebrospinal fluid to reach a thermal equilibrium. The cerebrospinal fluid flow is a molecular motion as a consequence of the gravity force and the Brownian movements. Conclusions : The Brownian motions are the driving forces for the cerebrospinal fluid bulk flow directed upwardly. The gravity force is the driving force for the cerebrospinal fluid bulk flow directed downwardly. The cerebrospinal fluid circulation in the spinal canal is like a corkscrew motion. doi:10.4021/jnr77w

How this classification was reachedexpand
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.
