Abstract

fetched live from OpenAlex

Let $G$ be a simple graph with vertex set $V(G)=\{v_{1},v_{2},$ $\dots,v_{n}\}$, and $G^{\sigma}$ be an orientation of $G$. Denote by $d(v_i)$ the degree of the vertex $v_i$ for $i=1,2,\dots,n$. The skew Randić matrix of $G^{\sigma}$, denoted by $R_S(G^{\sigma})$, is the real skew-symmetric matrix $(r_{ij})_{n\times n}$, where $r_{ij}={1}/{\sqrt{d(v_i)d(v_j)}}$ and $r_{ji}=-{1}/{\sqrt{d(v_i)d(v_j)}}$ if $v_i\rightarrow v_j$ is an arc of $G^{\sigma}$, otherwise $r_{ij}=r_{ji}=0$. The skew Randi\'{c} energy $\mathcal{RE}_S(G^{\sigma})$ of $G^{\sigma}$ is defined as the sum of the norms of all the eigenvalues of $R_S(G^{\sigma})$. In this paper, the oriented unicyclic graphs with minimal skew Randić energy are determined.

Full frame distilled prediction

Teacher imitation

Not 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.
