Aortic stenosis (AS) is now the most common indication for valve replacement in Europe and North America, with an ever increasing disease prevalence due to the ageing population (Iung B, Baron G, Butchart EG, Delahaye F, Gohlke-Bärwolf C, Levang AW, Tornos P, Vanoverschelde JL, Vermeer F, Boersma E, Ravaud P, Vahanian A. A prospective survey of patients with valvular heart disease in Europe: th...

A minimal representation of a simple non-compact Lie group is obtained by “quantizing” the minimal nilpotent coadjoint orbit of its Lie algebra. It provides context for Roger Howe’s notion of a reductive dual pair encountered recently in the description of global gauge symmetry of a (4-dimensional) conformal observable algebra. We give a pedagogical introduction to these notions and point out t...

Supermarkets might influence food choices, and more distal outcomes like obesity, by increasing the availability of healthy foods. However, recent evidence about their effects is ambiguous, perhaps because supermarkets also increase the availability of unhealthy options. We develop an alternative measure of food environment quality that characterizes urban neighborhoods by the relative amounts ...

As part of a larger program to identify low redshift radio analogues of the damped Lyman−α (DLA) absorbers seen in the spectra of high redshift quasars, Westerbork Synthesis Radio Telescope (WSRT) observations have discovered two new HI 21cm absorption lines at z = 0.394 and z = 0.437 in the spectra of the radio sources B 0248+430 and B 1243-072 respectively. These sightlines and redshifts were...

By use of a 3' extension PCR strategy, cDNA clones were isolated spanning the transmembrane region and a complete cytoplasmic domain of the human interleukin 5 receptor alpha subunit (hIL5R alpha). These cDNAs differ from previously isolated clones encoding a soluble hIL5R alpha form by a sequence switch at position 1243. When expressed in COS-1 cells, only low-affinity binding of 125I-labeled ...

The food and macronutrient intake of elite Kenyan runners was compared to recommendations for endurance athletes. Estimated energy intake (EI: 2987 +/- 293 kcal; mean +/- standard deviation) was lower than energy expenditure (EE: 3605 +/- 119 kcal; P < 0.001) and body mass (BM: 58.9 +/- 2.7 kg vs. 58.3 +/- 2.6 kg; P < 0.001) was reduced over the 7-d intense training period. Diet was high in car...

We perform specification tests of unbalanced panel data models for stock return prediction using an estimate of the coefficient covariance matrix robust to spatial heteroskedasticity. We apply estimators of individual effects and time effects in unbalanced panel models. For a panel of 1243 US firms for the period 1985–2002 we find that industry effects are significant and interact with firm cha...
