Torque about electrostatically charged spheres makes them more attractive Open
We show the surprising emergence of non-uniform charge distributions on shaken insulating spheres. The resulting inter-particle torques, coupled with the orientation dependent force, can substantially increase attraction.

Collective behavior of composite active particles Open
We describe simulations of active Brownian particles carried out to explore how dynamics and clustering are influenced by particle shape. Our particles are composed of four disks, held together by springs, whose relative size can be varied…

Congenital malformations and developmental disabilities in ataxia-telangiectasia, Fanconi anemia, and xeroderma pigmentosum families. Open
Heterozygous carriers of an ataxia-telangiectasia (A-T), Fanconi anemia (FA), or xeroderma pigmentosum (XP) gene may be predisposed to some of the same congenital malformations or developmental disabilities that are common among homozygote…

Effective testing of gene-disease associations. Open
We propose a method for testing any hypothesized association between a candidate allele, for which there is a specific laboratory test, and a common chronic disease. Families in which this allele is segregating are identified through index…

Power of sib-pair and sib-trio linkage analysis with assortative mating and multiple disease loci. Open
Sib-pair linkage analysis has been proposed for identifying genes that predispose to common diseases. The authors have shown that the presence of assortative mating and multiple disease-susceptibility loci (genetic heterogeneity) can incre…

Reduced Thermodynamic Description of Phase Separation in a Quasi-One-Dimensional Granular Gas Open
We describe simulations of a quasi-one-dimensional, vibrated granular gas which exhibits an apparent phase separation into a liquidlike phase and a gaslike phase. In thermal equilibrium, such a phase separation in one dimension is prohibit…

Magnetic Levitation Stabilized by Streaming Fluid Flows Open
We demonstrate that the ubiquitous laboratory magnetic stirrer provides a simple passive method of magnetic levitation, in which the so-called "flea" levitates indefinitely. We study the onset of levitation and quantify the flea's motion (…

Ice as a granular material Open
Ice is a unique material, fundamental to vital processes on earth, in the atmosphere [1] and as planets and comets form [2]. In this work, we introduce two experiments investigating ice as a granular material, to provide snippets of insigh…

Propulsion of a Two-Sphere Swimmer Open
We describe experiments and simulations demonstrating the propulsion of a neutrally buoyant swimmer that consists of a pair of spheres attached by a spring, immersed in a vibrating fluid. The vibration of the fluid induces relative motion …

A Maxwell Construction for Phase Separation in Vibrated Granular Matter? Open
Experiments and computer simulations are carried out to investigate ordering principles in a granular gas which phase separates under vibration. The densities of the dilute and the dense phase are found to follow a lever rule. A Maxwell co…
