After 100 years of effort, the classification of all the finite subgroups of SU(3) is yet incomplete. The most recently updated list can be found in [3], where the structure of the series (C) and (D) of SU(3)-subgroups is studied. We provide a minimal set of generators for one of these groups which has order 162. These generators appear up to phase as the image of an irreducible unitary braid g...

The topological structure of scalar, vector, and second-order tensor fields provides an important mathematical basis for data analysis and visualization. In this paper, we extend this framework towards higher-order tensors. First, we establish formal uniqueness properties for a geometrically constrained tensor decomposition. This allows us to define and visualize topological structures in symme...

BACKGROUND Secondhand smoke (SHS) exposure is higher among lower socioeconomic status (SES) children. Legislation restricting smoking in public places has been associated with reduced childhood SHS exposure and increased smoke-free homes. This paper examines socioeconomic patterning in these changes. METHODS Repeated cross-sectional survey of 10 867 schoolchildren in 304 primary schools in Sc...

The association between socioeconomic position (SEP) and serum lipids has been little studied and the results have been controversial. A total of 2063 young adults born in 1978/79 were evaluated at 23-25 years of age in the fourth follow-up of a cohort study carried out in Ribeirão Preto, SP, Brazil, corresponding to 31.8% of the original sample. Total serum cholesterol (TC), triglycerides, hig...

Essl et al. (1) tested whether historical socioeconomic conditions have created an invasion debt in Europe (i.e., a suite of nonnative species that have not yet been discovered but whose establishment has been determined by previous socioeconomic conditions). Essl et al. (1) tested this theory by asking whether the cumulative numbers of nonnative species presently established in 28 European cou...

OBJECTIVE To identify clusters of the major occurrences of leprosy and their associated socioeconomic and demographic factors. METHODS Cases of leprosy that occurred between 1998 and 2007 in São José do Rio Preto (southeastern Brazil) were geocodified and the incidence rates were calculated by census tract. A socioeconomic classification score was obtained using principal component analysis o...

INTRODUCTION Worldwide studies show inequalities in physical activity levels related to socio-demographic characteristics. In Colombia, among the countries in Latin America with the highest inequality, the evidence related to inequalities in physical activity is limited. It is imperative to identify disparities in physical activity in the country, to guide the design of public policies aimed at...

OBJECTIVES Immune response to cytomegalovirus (CMV) impacts adult chronic disease. This study investigates associations of childhood and adulthood social environment, socioeconomic position (SEP) and social mobility with CMV response in young adults. DESIGN Historical prospective study design. SETTING Subcohort of all 17 003 births to residents of Jerusalem between 1974 and 1976. PARTICIP...

BACKGROUND Scant research has taken a life-course perspective to explore the longitudinal impact of socioeconomic disadvantage and perceived social support on the psychological well-being of older women. We sought to explore whether socioeconomic disadvantage and perceived social support in mid-life are associated with subsequent depressive symptomatology among older Taiwanese women. METHODS ...
