Mapping vesicle shapes into the phase diagram: A comparison of experiment and theory. Abstract Phase-contrast microscopy is used to monitor the shapes of micron-scale fluid-phase phospholipid-bilayer vesicles in aqueous solution. At fixed temperature , each vesicle undergoes thermal shape fluctuations. We are able experimentally to characterize the thermal(More)
We consider in this paper the potential for ex ante prediction of the cascade size in a model of binary choice with externalities (Schelling 1973, Watts 2002). Agents are connected on a network and can be in one of two states of the world, 0 or 1. Initially, all are in state 0 and a small number of seeds are selected at random to switch to state1. A simple(More)
Using a biomembrane force probe decorated with P-selectin, discrete bonds were formed to PSGL-1 receptors on PMN surfaces and detached at speeds from ~ 1-100 µm/sec. High resolution tracking of the distance between probe tip and PMN revealed an initial elastic deformation that was either terminated by abrupt detachment or interrupted by yield and fluid-like(More)
Pulses of fine sediment in gravel-bedded rivers can cause extensive fine sediment infiltration (FSI) into void spaces in coarse bed material, potentially altering river morphodynamics and aquatic ecosystems. Previous work suggests a conceptual model of FSI whereby FSI occurs to a limited depth as a function of the relative grain size of bed sediment(More)
Acknowledgement: We acknowledge the intellectual input from a London-based financial sector company which wishes to remain anonymous, and in addition financial support from them 2 Abstract We examine in this paper the stability or otherwise of the financial system in Spain, and in particular the stability of the savings banks. We respond to the comments of(More)
each 90 min, were given each day. Birds that produced soft (subsong) vocalizations during tutoring were banded and transferred to individual custom sound attenuating chambers where tutoring continued until a total of 60 days was reached. Eight birds were tutored with the forward phrase-pair ensemble, eight others received tutoring with the reversed(More)
Species of Coralliophila are well-known cnidarian associates. Coralliophila clathrata, an obligate symbiont of the colonial zoanthid sea anemone Palythoa, feeds on nematocysts and zooxanthellae sloughed off in the host mucus (Robert-son 1980). Coralliophila abbreviata rapidly consumes coral tissues causing substantial colony mortality. Corallio-phila(More)
