We develop a general approach to robust inference about a scalar parameter when the data is potentially heterogeneous and correlated in a largely unknown way. The key ingredient is the following result of Bakirov and Székely (2005) concerning the small sample properties of the standard t−test: For a significance level of 5% or lower, the t−test remains conservative for underlying observations t...
The significance of tidal interactions in the evolution of the faint radio population (sub-mJy) is studied using a deep and homogeneous radio survey (1.4GHz), covering an area of 3.14deg and complete to a flux density of 0.4mJy. Optical photometric and spectroscopic data are also available for this sample. A statistical approach is employed to identify candidate physical associations between ra...

" Screening " of universal van der Waals – Casimir terms by Coulomb gases in a fully-finite two-dimensional geometry Abstract. This paper is a continuation of a previous one [Jancovici B andŠamaj L, 2004 J. Stat. Mech. P08006] dealing with classical Casimir phenomena in semi-infinite wall geometries. In that paper, using microscopic Coulomb systems, the long-ranged Casimir force due to thermal ...
NLIKE the better-known eight-spored species of Neurospora, N . tetrasperma usually produces asci with only four ascospores; each ascospore contains nuclei derived from two of the four meiotic products and is usually heterokaryotic for the mating type alleles. DODGE (1939) showed that eight-spored asci also occurred in N . tetrasperma, in crosses heterozygous for the pleiotropic gene E. Such cro...

PURPOSE We previously reported the prevalence of monoclonal gammopathy of undetermined significance (MGUS) to be 3.3% among an elderly Korean urban cohort recruited during 2005-2006. Here, we report a 5-year follow-up study of the previously identified MGUS cohort. MATERIALS AND METHODS The 680 participants from the initial cohort were followed-up for a median of 5 years. Sera were collected ...
Objective: to identify predictors of mortality among a national sample of elderly widowed people 28 years post-baseline interview. Design and setting: face to face home interview survey across England. Measures: physical, psychological, social, and socio-economic status and circumstances. Results: excess risk of mortality, which had been noted up to six months post bereavement among males aged ...
