Comment: Requires complete rewrite and more references to prove notability. The Herald (Benison) (talk) 07:01, 4 February 2024 (UTC)
Triangulation sensing is a theory describing the computational steps of a cell containing on its surface small windows, to estimate the location of a source emitting random particles in a medium. Particles are absorbed by the receptors.This theory is relevant for studying neuron navigation in the Brain[1][2]. Indeed, reconstructing the source location allows a navigating cell to triangulate its position. The reconstruction steps of the gradient source from the fluxes of diffusing particles arriving to small absorbing receptors are:
- Arrival of the Brownian particles to the small windows
- Counting particles at each window to estimated the fluxes
- Inversion of the Laplace's equation to estimate the source position from combining the fluxes.
- Accounr for possible noise reduction by applying the same procedure to multple several window triplets [3]
Samples of notable people included in this article can be found above.
Mathematical formulation based on solving the Laplace equation asymptotically[4]
The mathematical formulation consists in considering diffusing molecules that have to bind to N narrow windows located on the surface of a three dimensional shaped object, typically a ball (in dimension 3) or a disk in dimension 2. The number N can range between 10 and 50, but can be much higher for other receptor types. Individual Brownian particles are released from a source at position outside the ball. The triangulation sensing method consists in reconstructing the source position from estimated steady-state fluxes at each narrow window for fast binding (i.e. the probability density has an absorbing boundary condition at the windows).[5]
To reconstruct the location of a source from the measured fluxes, at least three windows are needed. Reconstructing the source location [6] requires to invert a system equation. With $N>3$ windows, numerical procedures are used to find the position of the source . The procedure can be accelerated by hybrid stochastic simulations.
