In this paper we report measurements of conductance fluctuations in single crystal samples of Si doped with P and B close to the critical composition of the metal insulator transition (nc ≈ 4 × 10 cm). The measurements show that the noise, which arises from bulk sources, does not diverge as the Ioffe-Regal limit (kF l → 1) is approached from the metallic side. At room temperatures, the magnitud...

Want to launch a virtual enterprise using the Web as your technology infrastructure? First learn what's missing from today's Web architecture and which extensions are needed for large-scale collaboration. T he WorldWide Web connects islands of information, along with the people seeking that information, from within corporate intranets and across the global Internet, easily and effectively. Shar...

Anderson(m) is a method for acceleration of fixed point iteration which stores m + 1 prior evaluations of the fixed point map and computes the new iteration as a linear combination of those evaluations. Anderson(0) is fixed point iteration. In this paper we show that Anderson(m) is locally r-linearly convergent if the fixed point map is a contraction and the coefficients in the linear combinati...

1 Introduction Disorder leads to important physical effects which are of quantum mechanical origin. This has been revealed by Anderson [1] in the study of a disordered tight-binding model. The problem has attracted great attention over many decades [2]. Subsequent to the ideas presented in our previous papers [3,4], we discuss here a new analytical approach to calculate the phase-diagram for th...

Open fractures usually are high-energy injuries. This, along with the exposure of bone and deep tissue to the environment, leads to increased risk of infection, wound complications, and nonunion [12, 28, 31]. Antibiotics, surgical débridement, and internal fixation have improved outcomes of open fracture management in important ways, but the underlying principles for treating open fractures hav...

Kathryn Anderson is Professor and Chair of the Developmental Biology Program at the Sloan Kettering Institute in New York. Her lab investigates the genetic networks underlying the patterning and morphogenesis of the early mouse embryo. We caught up with Kathryn at the 2016 Society for Developmental Biology - International Society of Differentiation joint meeting in Boston, where she was awarded...

This is a survey on the intermittent behavior of the parabolic Anderson model, which is the Cauchy problem for the heat equation with random potential on the lattice Z. We first introduce the model and give heuristic explanations of the long-time behavior of the solution, both in the annealed and the quenched setting for time-independent potentials. We thereby consider examples of potentials st...

FRONTIER CENTRE: In August the National Post published a provocative article in which you argue that Canada's rate of economic growth could out pace the impressive American rate and that Canada's standard of living could surpass that of our American cousins within twenty years should we adopt certain changes in public policy. Wouldn't such an about face, in fact, restore the Canadian advantage?...

Matthew T. Calef, Erin D. Fichtl, James S. Warsa, Markus Berndt, Neil N. Carlson, CCS-2 We compare variants of Anderson Mixing with the Jacobian-Free Newton-Krylov and Broyden methods applied to the k-eigenvalue formulation of the linear Boltzmann transport equation. We present evidence that one variant of Anderson Mixing finds solutions in the fewest number of iterations. We examine and streng...
