Bibliographic record
Abstract
The evolution of microstructure under swift heavy ion (SHI) irradiation is probed in a granular medium such as YBCO thick films prepared through diffusion reaction technique. From the temperature-dependent in situ resistivity measurement during ion irradiation, we have been able to isolate the irradiation induced modifications at the grain boundaries and the grains. With 120 MeV S ion irradiation, we show that in addition to damaging the insulating grain boundaries and hence destroying superconducting phase coherence, ion irradiation brings about an improvement in the microstructure of the cuprates. Irradiation is shown to induce alignment of the grains in an otherwise randomly oriented granular superconductor.
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.

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.
