This article is based on the covariant canonical formalism and corresponding symplectic structure on phase space developed by Witten, Zuckerman and others in the context of field theory. After recalling the basic principles of this procedure, we construct the conserved bilinear symplectic current for generic elastic string models. These models describe current carrying cosmic strings evolving i...

Introduction Consumer credit in the U.S. has continued to grow, partly due to marketing by lenders (Zuckerman, 2000). Assessment of the benefits and costs of loan consolidation is increasingly important in light of aggressive advertising by creditors and the financial difficulty faced by many families. A procedure for assessing loan consolidation is presented in this article. An analysis of sel...

We recently applied a multistage reweighting scheme to demonstrate the sampling of equilibrium configurational distributions of peptides from nonequilibrium, simulated annealing trajectories [E. Lyman and D. M. Zuckerman, J. Chem. Phys. 127, 065101 (2007)]. Here we demonstrate that a statistical variance reduction technique, resampling, improves the efficiency of the protocol by about a factor ...

In a recent breakthrough [CZ15], Chattopadhyay and Zuckerman gave an explicit two-source extractor for min-entropy k ≥ log n for some large enough constant C. However, their extractor only outputs one bit. In this paper, we improve the output of the two-source extractor to k, while the error remains n−Ω(1). Our improvement is obtained by giving a better extractor for (q, t, γ) non-oblivious bit...

We calculated diffusion timescales for Ca, Mg, Fe in hydrogen atmosphere white dwarfs with temperatures between 5000 and 25000 K. With these timescales we determined accretion rates for a sample of 38 DAZ white dwarfs from the recent studies of Zuckerman et al. (2003) and Koester et al. (2005). Assuming that the accretion rates can be calculated with the Bondi-Hoyle formula for hydrodynamic acc...

While the theoretical foundation for the conceptualisation of the corporate reputation, corporate trust and other related corporate constructs has been laid in Chapter 2, the methodological foundation for the conceptual research approach followed in this study is presented in this chapter. Existent literature suggests that conceptual research methods play a significant role in theory building, ...

This article treats the generalisation to brane dynamics of the covariant canonical variational procedure leading to the construction of a conserved bilinear symplectic current in the manner originally developped by Witten, Zuckerman and others in the context of field theory. After a general presentation, including a review of the relationships between the various (Lagrangian, Eulerian and othe...

We give the operadic formulation of (weak, strong) topological vertex algebras, which are variants of topological vertex operator algebras studied recently by Lian and Zuckerman. As an application, we obtain a conceptual and geometric construction of the Batalin-Vilkovisky algebraic structure (or the Gerstenhaber algebra structure) on the cohomology of a topological vertex algebra (or of a weak...

It is well-known that the standard no-ghost theorem is valid as long as the background has the light-cone directions. We prove the noghost theorem for the NSR string when only the timelike direction is flat. This is done by the BRST quantization, using the technique of Frenkel, Garland and Zuckerman and our previous results for the bosonic string. The theorem actually applies as long as the tim...
