Surface energy and the contact of elastic solids
This paper discusses the influence of surface energy on the contact between elastic solids. Equations are derived for its effect upon the contact size and the force of adhesion ...

The spandrels of San Marco and the Panglossian paradigm: a critique of the adaptationist programme
An adaptationist programme has dominated evolutionary thought in England and the United States during the past 40 years. It is based on faith in the power of natural selection a...
Model Selection and Estimation in Regression with Grouped Variables
Summary We consider the problem of selecting grouped variables (factors) for accurate prediction in regression. Such a problem arises naturally in many practical situations with...
Natural evaporation from open water, bare soil and grass
Two theoretical approaches to evaporation from saturated surfaces are outlined, the first being on an aerodynamic basis in which evaporation is regarded as due to turbulent tran...
The ERA‐40 re‐analysis
Abstract ERA‐40 is a re‐analysis of meteorological observations from September 1957 to August 2002 produced by the European Centre for Medium‐Range Weather Forecasts (ECMWF) in ...
Fast Stable Restricted Maximum Likelihood and Marginal Likelihood Estimation of Semiparametric Generalized Linear Models
Summary Recent work by Reiss and Ogden provides a theoretical basis for sometimes preferring restricted maximum likelihood (REML) to generalized cross-validation (GCV) for smoot...
On the variation of the initial mass function
(shortened) In this contribution an average or Galactic-field IMF is defined,\nstressing that there is evidence for a change in the power-law index at only\ntwo masses: near 0.5...
Smoothed particle hydrodynamics: theory and application to non-spherical stars
A new hydrodynamic code applicable to a space of an arbitrary number of dimensions is discussed and applied to a variety of polytropic stellar models. The principal feature of t...
