The “Reggeometry” model — universal impact parameter profile and Reggen behaviour — is applied to recent data on π+ p → π° (π+ p) at different energies and (π+p) missing masses, including Δ production. We are able, in pa...

Harvesting sequences which maximize the present value of an on-going forest are derived. Control theory is used to allow for various impingements on the rate of harvest. New harvesting rules are derived which generalize classical result...

Necessary and sufficient conditions for the existence of a common solution to the Lyapunov equation for two stable complex matrices are derived. These conditions are applied to the cases when a common weak solution to the Lyapunov equat...

Algorithms are developed which permit a more accurate calculation of rainbow properties from parametric potentials than has hitherto been practical. Tables of the rainbow properties are given for a number of Lennard-Jones and Morse pote...

Ordered sets are used as a computational model for motion planning in which figures on the plane may be moved along a ray emanating from a light source. The resulting obstructions give rise to ordered sets which, in turn, are precisely ...

Studies were made of the influence of the permeability of a magnetic conductor made of cast iron (3.2% carbon) and steel (0.2% carbon) on the efficiency of strong-field electromagnets. The permeability was modified within the range 1000...

Using the experimental sessions of Goeree and Holt (2005), we show that step thinking fits the long-run outcome of minimum-effort and median-effort games surprisingly well for all values of the cost parameter. In the latter, the predict...

Here it is shown that n points in the plane, no three on a line, always determine at least n slopes, with equality iff the n points are the vertices of an affinely regular polygon. Some bounds are also obtained on the minimum number of ...

We experimentally investigate the effect of Air Max 2011 Mens intergroup competition – with/out monetary incentives to win Buy Nike Air Max – on intragroup cooperation. In one-shot games, competition increases cooperation with/out i...

Reduction of the δ,ε-unsaturated aldehydes produced by tandem [2,3]-Wittig-anionic oxy-Cope rearrangement followed by stereoselective electrophilic cyclisation and reductive removal of the electrophile leads to single diastereoisomers...
