Betrayal and Betrayers - the Sociology of Treachery

Betrayal has a deep fascination. It captures our imagination in part because we have all betrayed or been betrayed, in small or large ways. Despite this there has been very little serious work on the subject. Betrayal is a breach of trust, when informants share beyond an agreed upon boundary of relations, whether that boundary is a pair of friends or a nation. Taking as a point of departure Simme

Human eeg responses to exact and statistical fractal patterns.

Attention Restoration Theory point to nature as a particularly good candidate for restoring the ability to focus and inhibit distractions. However, little effort has been directed to elaborating on what makes nature's visual pattern unique for restoration purposes. One suggested explanation is the fractal properties of natural patterns (Hagerhall, 2005). Both perception studies (Hagerhall et al.,

Transient waves from internal sources in non-stationary media - Numerical implementation

In this paper, the focus is on numerical results from calculations of scattered direct waves, originating from internal sources in non-stationary, dispersive, stratified media. The mathematical starting point is a general, inhomogeneous, linear, first order, 2 × 2 system of equations. Particular solutions are obtained, as integrals of waves from point sources distributed inside the scattering medi

$\eta$ and $\eta'$ Physics

This talk describes the reasons why $\eta$ and $\eta^\prime$ decays are an interesting topic of study for both theory and experiment. The main part discusses the results of the recent calculation of $\eta\to3\pi$ at two-loop order in ChPT. Some puzzling aspects of the results compared to earlier dispersive calculations are highlighted. I also like to remind the reader of the use of $\eta$ and $\et

Kinematically-equivalent but geomechanically-different simulations of fault evolution: the role of loading configurations

Geomechanical simulations are used to demonstrate the importance of the way that models are loaded. In this paper the development of permanent damage during faulting using frictional-slip models of a reverse fault is investigated. Although the use of different loads and constraints can produce the same faulted geometry (for the same rock type, and at the same burial depth), the models develop very
