Orthogonal and partly orthogonal reparametrisations are provided for certain wide and important families of univariate continuous distributions. First, the orthogonality of parameters in location-scale symmetric families is extended to symmetric distributions involving a third parameter. This sets the scene for consideration of the four-parameter situation in which skewness is also allowed. It ...

An optical gas sensor is presented, making use of a dispersed supercontinuum source, capable of acquiring broad bandwidth spectra at ultrahigh wavelength sweep and repetition rates. Wavelength sweeps from 1100 nm to 1700 nm can be performed in 800 ns at a spectral resolution of 40 pm. This is comparable to line-widths of molecular spectra at atmospheric pressure. Quantitative measurements are p...

Here we report a three-step growth method for high-quality mono-layer, bi-layer and tri-layer graphene with coverage ~90% at atmospheric pressure. The growth temperature and gas flow rate have been found to be the key factors. This method would be of great importance for the large scale production of graphene with defined thickness.

In this study we investigate the quality of the selection process of an open access (OA) journal, taking as an example the journal Atmospheric Chemistry and Physics (ACP). ACP is working with a new system of public peer review. We examined the predictive validity of the ACP peer review system – namely, whether the process selects the best of the manuscripts submitted. We have data for 1111 manu...

Numerical simulation of streamer propagation in nitrogen at atmospheric pressure" (1985).

Modifications which enable simpler operation of the Cunningham-Barth-Kirk microrespirometer are described and an example of its use is quoted. Added advantages include easy positioning of indicator drop in the capillary and thermal equilibration at atmospheric pressure.

We obtain the topological configurations of the lines of curvature, the asymptotic and characteristic curves on a cross-cap, in the domain of a parametrisation of this surface as well as on the surface itself.
