INTRODUCTION With the ease provided by current computational programs, medical and scientific journals use bar graphs to describe continuous data. METHODS This manuscript discusses the inadequacy of bars graphs to present continuous data. RESULTS Simulated data show that box plots and dot plots are more-feasible tools to describe continuous data. CONCLUSIONS These plots are preferred to r...

Outer rings are located at the greatest distance from the galaxy center of any feature resonant with a bar. Because of their large scale, their morphology is sensitive to the distribution of the dark matter in the galaxy. We introduce here how study of these rings can constrain the mass-to-light ratio of the bar, and so the percentage of dark matter in the center of these galaxies. We compare p...

We investigate the scaling properties of the speciic heat of the XY model on lattices H H L with L H (i.e. in a bar-like geometry) with respect to the thickness H of the bar, using the Cluster Monte Carlo method. We study the eeect of the geometry and boundary conditions on the shape of the universal scaling function of the speciic heat by comparing the scaling functions obtained for cubic, lm,...

We present a deep near-infrared wide-angle photometric analysis of the structure of the inner Galactic bar and central disk. The presence of a triaxial structure at the centre of the Galaxy is confirmed, consistent with a bar inclined at 22±5.5 • from the Sun-Galactic centre line, extending to about 2.5 kpc from the Galactic centre and with a rather small axis ratio. A feature at ℓ=−9.8 • not a...

The detailed structure of multidigit receptive fields (RFs) in somatosensory cortical areas such as the SII region has not been investigated previously using systematically controlled stimuli. Recently (Fitzgerald et al., 2004), we showed that the SII region comprises three adjoining fields: posterior, central, and anterior. Here we characterize the RF structures of the 928 neurons that were re...

Persistent homology ([3], [13]) is a fundamental tool in the area of computational topology. It can be used to infer topological structure in data sets (see [1], [4]), but variations on the method can be applied to study aspects of the shape of point clouds which are not overtly topological ([5], [8]). The methodology assigns to any finite metric space (such as are typically obtained in experim...

We investigate the role of lithographically-induced strain relaxation in a micron-scaled device fabricated from epitaxial thin films of the magnetostrictive alloy Fe81Ga19. The strain relaxation due to lithographic patterning induces a magnetic anisotropy that competes with the magnetocrystalline and shape induced anisotropies to play a crucial role in stabilising a flux-closing domain pattern....

I summarize a series of studies where the underlying theme is to exploit non-axisymmetry disk structures such as bars and spiral arms. By measuring the strength of gravitational forces from these structures we can measure the mass in them. The advantage of this approach is that mass to light ratios can be constrained in a way independent of the dark matter profile. By examining a variety of typ...

Membrane-sculpting BAR (Bin/Amphiphysin/Rvs) domains form a crescent-shaped homodimer that can sense and induce membrane curvature through its positively charged concave face. We have recently shown that Arfaptin-2, which was originally identified as a binding partner for the Arf and Rac1 GTPases, binds to Arl1 through its BAR domain and is recruited onto Golgi membranes. There, Arfaptin-2 indu...
