The Early California Cultural Atlas

The Early California Cultural Atlas (ECCA) is envisioned as an interactive website that will integrate and manage historical resources, enable analysis of historical data related to the colonization and settlement of California, display research results in the form of maps and other visualizations, and educate students from elementary school to the university. This project is interdisciplinary and collaborative; it will draw upon the expertise of librarians, archivists, research scholars, software engineers, technical experts, California Indians, and primary school teachers. The ECCA represents a new partnership between existing programs, innovative scholars, and accomplished educators

The Early California Cultural Atlas

European settlement in North America and the establishment of missions to Indians initiated dramatic demographic, environmental, religious, and social change. The Early California Cultural Atlas (ECCA) is a digital history project that seeks to further explore and illuminate these historical developments in colonial California between 1769 and 1850. The ECCA is an emerging interactive website that integrates and manages historical resources, enables analysis of data related to the colonization and settlement of California, displays research results in the form of maps and other visualizations, and educates students from elementary school to the university. This project draws upon the expertise of librarians, archivists, historians, anthropologists, geographers, software engineers, technical experts, California Indians, and primary school teachers

Metastable lifetimes in a kinetic Ising model: Dependence on field and system size

The lifetimes of metastable states in kinetic Ising ferromagnets are studied by droplet theory and Monte Carlo simulation, in order to determine their dependences on applied field and system size. For a wide range of fields, the dominant field dependence is universal for local dynamics and has the form of an exponential in the inverse field, modified by universal and nonuniversal power-law prefactors. Quantitative droplet-theory predictions are numerically verified, and small deviations are shown to depend nonuniversally on the details of the dynamics. We identify four distinct field intervals in which the field dependence and statistical properties of the lifetimes are different. The field marking the crossover between the weak-field regime, in which the decay is dominated by a single droplet, and the intermediate-field regime, in which it is dominated by a finite droplet density, vanishes logarithmically with system size. As a consequence the slow decay characteristic of the former regime may be observable in systems that are macroscopic as far as their equilibrium properties are concerned.Comment: 18 pages single spaced.

Growth of laser damage in fused silica: diameter to depth ratio

Growth of laser initiated damage plays a major role in determining optics lifetime in high power laser systems. Previous measurements have established that the lateral diameter grows exponentially. Knowledge of the growth of the site in the propagation direction is also important, especially so when considering techniques designed to mitigate damage growth, where it is required to reach all the subsurface damage. In this work, we present data on both the diameter and the depth of a growing exit surface damage sites in fused silica. Measured growth rates with both 351 nm illumination and with combined 351 nm and 1054 nm illumination are discussed
