Abstract
Single crystals of ${\mathrm{Ce}}_{3+x}{\mathrm{Ru}}_{4}{\mathrm{Sn}}_{13\ensuremath{-}x}$ $(0.05\ensuremath{\le}x\ensuremath{\le}0.34)$, which adopt the cubic structure ($Pm\overline{3}n$, No. 223), have been grown with Sn flux. Thermodynamic and transport property measurements from single-crystal samples do not show any sign of magnetic ordering down to 1.8 K and indicate coexistence of the Kondo effect and crystalline electric field effect. The local minimum in the electrical resistivity and highly enhanced specific heat values at low temperatures characterize this family as a heavy fermion Kondo lattice system. A broad peak is observed at $\ensuremath{\sim}$3.5 K for $x=0.05$ in the specific heat and magnetic susceptibility, suggesting a significant Kondo contribution, and the peak disappears as $x$ increases. The evolution of physical properties of ${\mathrm{Ce}}_{3+x}{\mathrm{Ru}}_{4}{\mathrm{Sn}}_{13\ensuremath{-}x}$ compounds can be attributed to the nature of the individual Ce ions that occupy two inequivalent $2a$ and $6d$ crystallographic sites.

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; both teacher heads agree on what is shown here.
