Discussion has mainly focussed on the values of the rate various physical properties such as crystal size, ice fabric, and impurity content have been measured along the length of the core (Hammer and others, 1985; Herron and others, 1985). The bore hole itself has been studied for tilting and closure rates (Gundestrup and Hansen, 1984). In addition, there are three sets of ice-sounding radar su...

Capital market imperfections are widely believed to explain why consumption deviates from the martingale implications of the REPIH. However, empirical modelling and theoretical analysis of consumption under capital market imperfections is hindered by the absence of any tractable theoretical model. By modelling capital market imperfections as consumers facing an upward sloping interest rate sche...

[1] We present an experimental and numerical study of a rotating fluid with a zonal flow produced from small-scale eddies, a common feature of many planetary systems. The apparatus consists of a water-filled annular tank with a sloped bottom. Flow is forced mechanically at small, nonaxisymmetric scales. Potential vorticity is materially conserved and well-mixed. This implies the existence of no...

To draw valid inference about an indirect effect in a mediation model, there must be no omitted confounders. No omitted confounders means that there are no common causes of hypothesized causal relationships. When the no-omitted-confounder assumption is violated, inference about indirect effects can be severely biased and the results potentially misleading. Despite the increasing attention to ad...

Laboratory experiments are carried out to detect optical vortices in conditions typical of those experienced when a laser beam is propagated through the atmosphere. A Spatial Light Modulator (SLM) is used to mimic atmospheric turbulence and a Shack-Hartmann wavefront sensor is utilised to measure the slopes of the wavefront surface. A matched filter algorithm determines the positions of the Sha...

A problem of sound propagation in a shallow-water waveguide with a weakly sloping penetrable bottom is considered. The adiabatic mode parabolic equations are used to approximate the solution of the three-dimensional (3D) Helmholtz equation by modal decomposition of the acoustic pressure field. The mode amplitudes satisfy parabolic equations that admit analytical solutions in the special case of...

We have performed broadband color photometry of the twelve brightest irregular satellites of Saturn with the goal of understanding their surface composition, as well as their physical relationship. We find that the satellites have a wide variety of different surface colors, from the negative spectral slopes of the two retrograde satellites S IX Phoebe (S′ = −2.5± 0.4) and S XXV Mundilfari (S′ =...

In this experiment, the acoustic correlates of perceived emotions in singing were investigated. Singers were instructed to sing one phrase in a neutral way and in the emotions anger, joy, fear, and sadness. Listeners rated the strength of the perceived emotions for each fragment. Principal component analyses were performed on the listeners’ ratings. The derived factors were interpreted as liste...
