A {surd}t-Warped Wave Transform Reveals Multi-Scale Electrical Rhythms in Fungal Networks
Knowles, J.
Show abstract
Fungal electrical activity exhibits spikes and slow oscillatory modulations over seconds to hours. We introduce a {surd}t-warped wave transform that concentrates long-time structure into compact spectral peaks, improving time-frequency localization for sublinear temporal dynamics. On open fungal datasets (fs{approx}1 Hz) the method yields sharper spectra than STFT, stable {tau}-band trajectories, and species-specific multi-scale "signatures." Coupled with spike statistics and a lightweight ML pipeline, we obtain reproducible diagnostics under leave-one-file-out validation. All analyses are timestamped, audited, and designed for low-RAM devices.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
