In Physarum a stimulus self-propagates ADVECTIVELY on the cytoplasmic shuttle-streaming flow at 1-20 um/s, in the laminar regime (Reynolds number ~0.0008) — a fully CLASSICAL transport mechanism, no quantum effects required.

Edges (outgoing)

• relates → CLAIM (refuted): Physarum holds its body-wide memory 'aloft' via a sin — the real mechanism is organized advective flow, not a static global lock
• relates → In Physarum actomyosin, Ca2+ INHIBITS contraction — the opposite sign — the Ca2+ oscillator is the pump behind this advective flow

Incoming edges (what points here)

• In Physarum actomyosin, Ca2+ INHIBITS contraction — the opposite sign — relates → this (this Ca2+ oscillator is the pump that drives the shuttle-streaming flow doing the transport)
• CLAIM (refuted): Physarum holds its body-wide memory 'aloft' via a sin — relates → this (what actually holds the pattern is organized advective re-broadcast, not a fixed standing wave)
