Limbic Regression with Derepression of Oedipal Feelings
Most knowledge of the normal preschool oedipal feelings for a parent of the opposite sex
come from reconstructive analysis of neurologically normal adults or from observation of phallic
stage children. We have discovered in the symptoms of a severely brain-damaged adolescent
evidence of a slightly different and interesting type. It seems to result from a biological unmasking
of repressed material by post-encephalitic age regression
Avalanches in Breakdown and Fracture Processes
We investigate the breakdown of disordered networks under the action of an
increasing external---mechanical or electrical---force. We perform a mean-field
analysis and estimate scaling exponents for the approach to the instability. By
simulating two-dimensional models of electric breakdown and fracture we observe
that the breakdown is preceded by avalanche events. The avalanches can be
described by scaling laws, and the estimated values of the exponents are
consistent with those found in mean-field theory. The breakdown point is
characterized by a discontinuity in the macroscopic properties of the material,
such as conductivity or elasticity, indicative of a first order transition. The
scaling laws suggest an analogy with the behavior expected in spinodal
nucleation.Comment: 15 pages, 12 figures, submitted to Phys. Rev. E, corrected typo in
