The Hoop Conjecture in Spherically Symmetric Spacetimes [PDF]
We give general sufficient conditions for the existence of trapped surfaces due to concentration of matter in spherically symmetric initial data sets satisfying the dominant energy condition.

Antagonistic Regulation of Neurite Morphology through Gq/G11 and G12/G13 [PDF]
The induction of neurite retraction and growth cone collapse via G-protein-coupled receptors is involved in developmental as well as regenerative processes. The role of individual G-protein-mediated signaling processes in the regulation of neurite morphology is still incompletely understood. Using primary neurons from brains lacking Galpha(q)/Galpha(11)

Tophaceous Gout of the Patella: A Report of Two Cases
Introduction. Tophaceous gout of the patella is rare and may masquerade as a tumour or tumour-like condition. Cases. We report two patients with gout involving the patella, one complicated by a pathological fracture and the other occurring in a bipartite

The White Dwarfs within 25 Parsecs of the Sun: Kinematics and Spectroscopic Subtypes [PDF]
We present the fractional distribution of spectroscopic subtypes, range and distribution of surface temperatures, and kinematical properties of the white dwarfs within 25pc of the sun.

Peptide Vocabulary Analysis Reveals Ultra-Conservation and Homonymity in Protein Sequences
A new algorithm is presented for vocabulary analysis (word detection) in texts of human origin. It performs at 60%–70% overall accuracy and greater than 80% accuracy for longer words, and approximately 85% sensitivity on Alice in Wonderland , a ...

Hydrodynamic transport functions from quantum kinetic theory [PDF]
Starting from the quantum kinetic field theory [E. Calzetta and B. L. Hu, Phys. Rev. D37, 2878 (1988)] constructed from the closed-time-path (CTP), two-particle-irreducible (2PI) effective action we show how to compute from first principles the shear and

A generalization of Szebehely's inverse problem of dynamics in dimension three [PDF]
Extending a previous paper, we present a generalization in dimension 3 of the traditional Szebehely-type inverse problem. In that traditional setting, the data are curves determined as the intersection of two families of surfaces, and the problem is to ...

Commuting involutions of Lie algebras, commuting varieties, and simple Jordan algebras [PDF]
We study certain "\sigma-commuting varieties" associated with a pair of commuting involutions of a semisimple Lie algebra $\g$. The usual commuting variety of $\g$ and commuting varieties related to one involution are particular cases of our construction.
