Stimulus Intensity and Modulation of Brain Output
Biophysical Journal, 1973 In accordance with the implications of a previously proposed mathematical model of modulation of bioelectric response in the brain, it is found that a single free coefficient predicts the observed modulation periods over a range of stimulus intensities ...

An Optically Pumped Magnetometer with Omnidirectional Magnetic Field Sensitivity
Sensors, 2023 In mobile applications such as geomagnetic surveying, two major effects hamper the use of optically pumped magnetometers: dead zones, sensor orientations where the sensors signal amplitude drops; and heading errors, a dependence of the measured magnetic ...
