Magnetic imaging of Pearl vortices
We have used scanning SQUID magnetometry to image vortices in ultra-thin [Ba$_{0.9}$Nd$_{0.1}$CuO$_{2+x}$]$_m$/[CaCuO$_2$]$_n$ (CBCO) high temperature superconductor samples, with as few

Two-pearl Strings: Feynman's Oscillators
String models are designed to provide a covariant description of internal space-time structure of relativistic particles. The string is a

Dark Matter-Wave Solitons in Optical Lattices
We analyze the Floquet-Bloch matter-wave spectrum of Bose-Einstein condensates loaded into single-periodic optical lattices and double-periodic superlattices. In the framework

Axiomatizing Causal Reasoning
Causal models defined in terms of a collection of equations, as defined by Pearl, are axiomatized here. Axiomatizations are provided

Single chain properties of polyelectrolytes in poor solvent
Using molecular dynamics simulations we study the behavior of a dilute solution of strongly charged polyelectrolytes in poor solvents, where

An Open Ended Tree
An open ended list is a well known data structure in Prolog programs. It is frequently used to represent a

Directional Consistency for Continuous Numerical Constraints
Bounds consistency is usually enforced on continuous constraints by first decomposing them into binary and ternary primitives. This decomposition has

Direct measurement of single fluxoid dynamics in superconducting rings
We have measured the dynamics of individual magnetic fluxoids entering and leaving thin film, photolithographically patterned rings of underdoped high-temperature

Elastic Properties of the Vortex Lattice for a Superconducting Film of Finite Thickness
In this paper we investigate the elastic properties of the vortex lattice for a superconducting film of finite thickness. We

Iterated revision and the axiom of recovery: a unified treatment via epistemic states
The axiom of recovery, while capturing a central intuition regarding belief change, has been the source of much controversy. We

Polyelectrolyte gels in poor solvent: Equilibrium and non equilibrium elasticity
We study theoretically using scaling arguments the behavior of polyelectrolyte gels in poor solvents. Following the classical picture of Katchalsky,

Probabilistic Default Reasoning with Conditional Constraints
We propose a combination of probabilistic reasoning from conditional constraints with approaches to default reasoning from conditional knowledge bases. In

Responsibility and blame: a structural-model approach
Causality is typically treated an all-or-nothing concept; either A is a cause of B or it is not. We extend

What Causes a System to Satisfy a Specification?
Even when a system is proven to be correct with respect to a specification, there is still a question of
