Abstract

fetched live from OpenAlex

<ns5:p> We present a genome assembly from an individual <ns5:italic>Spongilla lacustris</ns5:italic> (freshwater sponge; Porifera; Demospongiae; Spongillida; Spongillidae). The genome sequence is 248.7 megabases in span. Most of the assembly is scaffolded into 23 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 28.04 kilobases in length. A 14.6-megabase genome assembly of the green algal cobiont <ns5:italic>Choricystis</ns5:italic> sp. (Chlorophyta; Trebouxiophyceae) was scaffolded into 16 chromosomal pseudomolecules. Additionally, three bacterial metagenome bins were recovered from the same sample. Gene annotation of this assembly at Ensembl identified 30,435 protein coding genes. </ns5:p>

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 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.
