An energy principle for hydromagnetic stability problems
The problem of the stability of static, highly conducting, fully ionized plasmas is investigated by means of an energy principle developed from one introduced by Lundquist. The ...

Model Uncertainty, Data Mining and Statistical Inference
This paper takes a broad, pragmatic view of statistical inference to include all aspects of model formulation. The estimation of model parameters traditionally assumes that a mo...
An application of normal mode theory to the retrieval of structural parameters and source mechanisms from seismic spectra
A cyclic process of refining models of the mechanical structure of the Earth and models of the mechanism of one or more earthquakes is developed. The theory of the elastic-gravi...
Willed action and the prefrontal cortex in man: a study with PET
We used positron emission tomography to contrast changes in cerebral blood flow associated with willed and routine acts. In the six tasks used, volunteers had to make a series o...
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: baryon acoustic oscillations in the Data Release 9 spectroscopic galaxy sample
We present measurements of galaxy clustering from the Baryon Oscillation\nSpectroscopic Survey (BOSS), which is part of the Sloan Digital Sky Survey III\n(SDSS-III). These use t...
Precision photometry of early-type galaxies in the Coma and Virgo clusters: a test of the universality of the colour-magnitude relation - II. Analysis
We have undertaken a detailed comparison of the colours of early-type galaxies in the Virgo and Coma clusters. In Paper I (this issue), we presented our system of homogeneous U,...
The molecular orbital theory of chemical valency VIII. A method of calculating ionization potentials
An analysis of the ‘linear combination of atomic orbitals’ approximation using the accurate molecular orbital equations shows that it does not lead to equations of the form usua...
Operating Characteristics and Extensions of the False Discovery Rate Procedure
Summary We investigate the operating characteristics of the Benjamini–Hochberg false discovery rate procedure for multiple testing. This is a distribution-free method that contr...
The wave motion of a revolving shaft, and a suggestion as to the angular momentum in a beam of circularly polarised light
When a shaft of circular section is revolving uniformly, and is transmitting power uniformly, a row of particles originally in a line parallel to the axis will lie in a spiral o...
