🧬 Segmentation Clock and Wavefront: her1 Delay Oscillator, FGF Gradient and Somite Boundaries

Segmentation clock and wavefront lab: a lattice of her1/her7 delayed-feedback oscillators flows through the presomitic mesoderm, an FGF gradient sets the determination front and somite boundaries appear with length S = v T, with Delta-Notch coupling, noise, a kymograph, a speed sweep and six in-page numerical checks.
