Making the small oblique parameters large
We compute the oblique parameters, including the three new parameters ,
and introduced recently by the Montreal group, for the case of one
scalar multiplet of arbitrary weak isospin and weak hypercharge . We
show that, when the masses of the heaviest and lightest components of the
multiplet remain constant, but increases, the oblique parameter and
the three new oblique parameters increase like , while only
increases like . For large multiplets with masses not much higher than , the oblique parameters and may become much larger than
and .Comment: 9 pages, standard LATEX, 3 figures available from the authors, report

Constraining the orbits of sub-stellar companions imaged over short orbital arcs
Imaging a star's companion at multiple epochs over a short orbital arc
provides only four of the six coordinates required for a unique orbital
solution. Probability distributions of possible solutions are commonly
generated by Monte Carlo (MCMC) analysis, but these are biased by priors and
may not probe the full parameter space. We suggest alternative methods to
characterise possible orbits, which compliment the MCMC technique. Firstly the
allowed ranges of orbital elements are prior-independent, and we provide means
to calculate these ranges without numerical analyses. Hence several interesting
constraints (including whether a companion even can be bound, its minimum
possible semi-major axis and its minimum eccentricity) may be quickly computed
using our relations as soon as orbital motion is detected. We also suggest an
alternative to posterior probability distributions as a means to present
possible orbital elements, namely contour plots of elements as functions of
line of sight coordinates. These plots are prior-independent, readily show
degeneracies between elements and allow readers to extract orbital solutions
themselves. This approach is particularly useful when there are other
constraints on the geometry, for example if a companion's orbit is assumed to
be aligned with a disc. As examples we apply our methods to several imaged
sub-stellar companions including Fomalhaut b, and for the latter object we show
how different origin hypotheses affect its possible orbital solutions. We also
examine visual companions of A- and G-type main sequence stars in the
Washington Double Star Catalogue, and show that per cent must be
unbound.Comment: Accepted for publication in MNRA

Computing the Loewner driving process of random curves in the half plane
We simulate several models of random curves in the half plane and numerically
compute their stochastic driving process (as given by the Loewner equation).
Our models include models whose scaling limit is the Schramm-Loewner evolution
(SLE) and models for which it is not. We study several tests of whether the
driving process is Brownian motion. We find that just testing the normality of
the process at a fixed time is not effective at determining if the process is
Brownian motion. Tests that involve the independence of the increments of
Brownian motion are much more effective. We also study the zipper algorithm for
numerically computing the driving function of a simple curve. We give an
implementation of this algorithm which runs in a time O(N^1.35) rather than the
usual O(N^2), where N is the number of points on the curve.Comment: 20 pages, 4 figures. Changes to second version: added new paragraph

Arkansas Cotton Variety Test 2012
The primary goal of the Arkansas Cotton Variety Test is to provide unbiased data regarding the agronomic performance of cotton varieties and advanced breeding lines in the major cotton-growing areas of Arkansas. This information helps seed companies establish marketing strategies and assists producers in choosing varieties to plant
