For the classical Polya urn model parametrized by exponent γ, the limit distributions of the fraction of balls in each bin are simple and well known when γ < 1 (“egalitarian”) and when γ > 1 (“winner takes all”). In this note, we partially fill in the gap for γ = 1, the critical point, by providing explicit analytical expressions for all the moments of the limit distribution of the fraction of ...

Over a 4 year period, nine of 180 (5%) infants weighing less than 2000 G,admitted to the Aga Khan University Hospital (AKUH) developed necrotizing enterocolitis (NEC). An outbreak of NEC occurred in 1989, during which six infants developed the clinical illness. Overall incidence was 1.1%. Thirty-one birth weight and gestation matched controls were selected for comparison. Risk factors usually c...

We study the possibility for a measurement of neutrino mass using weak gravitational lensing. The presence of non-zero mass neutrinos leads to a suppression of power at small scales and reduces the expected weak lensing signal. The measurement of such a suppression in the weak lensing power spectrum allows a direct measurement of the neutrino mass, in contrast to various other experiments which...

Mutually unbiased weighing matrices (MUWM) are closely related to an antipodal spherical code with 4 angles. In this paper, we clarify the relation between MUWM and the spherical codes, and determine the maximum size of a set of MUWM with weight 4 for any order. Moreover, we define mutually quasi-unbiased weighing matrices (MQUWM) as a natural generalization of MUWM from the viewpoint of spheri...

− This research deals with a weighing system used under the conditions in which various movements exist. These various movements are heaving motion, rolling motion, pitching motion, etc. In this paper, these various movements are collectively called as “vibration-like movements”. The term of “vibration-like moving conditions” means the conditions in which vibration-like movements exist. In the ...

OBJECTIVE Frequent self-weighing is linked with weight management success, but concern has been raised about its possible association with unhealthy practices. This study examined the association of self-weighing with other weight control behaviors in a sample for whom frequent weighing might be questioned--namely, normal-weight or overweight (BMI of 21-29.9) young adults (age 18-35). METHODS...

OBJECTIVE To describe the prevalence of self-weighing in the transition period from adolescence to young adulthood and examine cross-sectional and longitudinal associations between self-weighing and weight status, psychological, and behavioral outcomes. DESIGN Project Eating and Activity in Teens and Young Adults, a longitudinal cohort study that assessed variables 3 times over 10 years. PA...

The purpose of the study was to describe the range of relative backpack weights of one group of elementary-aged children and the extent to which they exceeded recommended levels. A second purpose was to explore whether gender and age help predict the relative weight of children's backpacks. Ninety-five 8- to 12-year-old elementary school students (56% girls; 88% car or bus riders) participated....

a disorder that is generally restricted to infants weighing less than 1001 g at birth. The size of the surviving population of infants with ROP dwarfs all previous predictions of absolute numbers because survival rates of infants weighing 501-750 g at birth are now approaching 60%, and those of infants weighing 751-1000 g are now approaching 90%. The total incidence of ROP in infants weighing 5...
