What existing studies can constrain in BERM now — and what still requires a calibrated L2 kernel.
The literature closes several literature-search gaps. It supports state-dependent response families involving phase, coherence duration, pulse shape, developmental timing, receptor or agonist state, redox state and co-exposure. Organ transfer and BERM's geometry-to-tissue calibration remain open.
BERM therefore writes the endpoint response as a retarded, state-conditional kernel rather than a universal weighted sum:
Sᵣ includes background magnitude and direction, polarization, envelope spectrum, coherence time, circadian and metabolic phase, developmental window, receptor/agonist state, redox state, genotype, organ transfer and exposure history. FieldState may measure physical members of Sᵣ; BERM owns the biological kernel and endpoint mapping.
Experimental setup illustration
Compare two example setups. Choose one difference and see what needs to be recorded around the sample.
Coil pair and sample stage
Coil pair and sample stage
The same device setting can meet differently oriented samples. Here the sample's reference axis rotates while the coils and background direction stay fixed.
Record for the comparisonThe sample reference axis, source field vector and local B₀ vector in the same coordinate system.
A directional sample is used as an example. Sample posture, probe orientation and the biologically relevant receiving direction are different quantities. Rotation alone does not specify the sign or size of a response.
In both setups. Record the sample, life stage and handling, the source's actual waveform and field components, the local B₀ vector, probe calibration, measurement time and temperature. Blinding, sham conditions and the biological endpoint belong in the actual experiment's protocol.
This is an example setup illustration. It does not reproduce a named study or display a biological result. Comparing a conditional BERM response also requires a specified receiver and endpoint; missing information is not evidence of a hidden effect.
For matched single- and combined-channel experiments, BERM stores both the additive contrast I₊ = Y₁₂ − Y₁ − Y₂ + Y₀ and the log-multiplicative contrast I× = log(Y₁₂/Y₀) − log(Y₁/Y₀) − log(Y₂/Y₀). Positive, null and negative values are all admissible. The model no longer assumes that combined channels must always be supra-additive.
Each row constrains a response condition. None supplies an environmental population dose or a TFR coefficient.
