Target strength spectra of swim-bladdered fish [PDF]
The Journal of the Acoustical Society of America, 1999 Swim-bladdered fish are modeled by the actual shape of the swimbladder as determined from microtomed sections. Target strength spectra are computed for specimens of pollack (Pollachius pollachius) and saithe (Pollachius virens). Results obtained with both the Kirchhoff approximation and boundary-element method at each of four ultrasonic frequencies are

Taking Heisenberg's Potentia Seriously [PDF]
, 2017 It is argued that quantum theory is best understood as requiring an ontological duality of res extensa and res potentia, where the latter is understood per Heisenberg's original proposal, and the former is roughly equivalent to Descartes' 'extended ...
