“A Computational Investigation of Strain Concentration in the Brain in Response to a Rapid Temperature Rise,” Journal of the Mechanical Behavior of Biomedical Materials, March 2021. Microwave pulses and embassy illness: Computer simulations show importance of how long they are (or more importantly, how short) to cause potential ill effects in the brain: “Decreasing the pulse duration increases the magnitude of focused stress.”
