Infrared Radiation Sensors of <I>Melanophila acuminata</I> (Coleoptera: Buprestidae): A Thermopneumatic Model
Bibliographic record
Abstract
A description of the fine structure of the infrared radiation (IR) sensor of Melanophila acuminata (De Geer) and of the role of the wings during flight in mechanically modulating incoming IR into on and off pulses, supports a thermopneumatic model of IR perception by this insect. The model postulates that pulsed IR, corresponding to wavelengths emitted by fires, enters an enclosed, airtight, thick-walled cavity in each sensor through an apical epicuticular waveguide and is absorbed by a thin, chitinous endocuticular lamella of the cavity wall. The lamella is heated and in turn heats and expands the enclosed air that then compresses a basal cuticular cap that displaces the tubular body of the sensor, triggering a dendritic impulse and transducing an action potential in the neuron. This process is possible because of the absorption by the chitinous lamella of the wavelengths of IR emitted by fires resulting in extraordinary IR wavelength discrimination, radiant energy sensitivity, and rapid response time. These properties distinguish the sensor from temperature sensors of insects, sometimes erroneously designated as IR sensors, that respond relatively slowly to broadband wavelength radiation.

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.
