A basic kinetic model that incorporates a coupled dynamics of the carbon atoms and dimers on a copper surface is used to compute growth of a single-layer graphene island. The speed of the island’s edge advancement on Cu[111] and Cu[100] surfaces is computed as a function of the growth temperature and pressure. Spatially resolved concentration profiles of the atoms and dimers are determined, and...

1 Introduction Decades of psycholinguistic research have witnessed a sustained interest in whether syntactic island constraints are active during online processing the study of syntactic islands seeks to identify environments in which filler-gap dependencies are banned. But to these generalizations, there are, of course, exceptions. One of the more resilient island constraints is Ross's (1967) ...

Geological history of oceanic islands can have a profound effect on the evolutionary history of insular flora, especially in complex islands such as Tenerife in the Canary Islands. Tenerife results from the secondary connection of three paleo-islands by a central volcano, and other geological events that further shaped it. This geological history has been shown to influence the phylogenetic his...

[1] We utilize seismic converted phases on more than 700 receiver functions calculated for 42 stations in the South Island, New Zealand, to infer crustal and uppermost mantle structure. We determine the crustal thickness from direct observations of conversion from the Moho interface and infer zone of the maximum thickness being located along the axis of the Southern Alps, just east from the Alp...

A new retrieval technique has been developed which resolves some of the vertical structure of lower tropospheric water vapor over Oceans from space. 'The relationship is demonstrated by comparisons between direct measurements of the water vapor profile, by radiosondes, and coincident estimates of the horizontal turbulence structure of Integrated Water Vapor, wing the TOPEX Microwave Radiometer ...

The Island of Hawaii is the youngest and southeasternmost member of a quasi-linear, age-ordered, chain of volcanic islands and seamounts which extends for 3500 km across the northwestern Pacific sea floor. Similarities between the Hawaiian chain and at least six other linear island chains of the Pacific basin, including their nearly unidirectional and uniform rate of extension, WNW orientation,...

Microphase separation of mixed A∕B polymer brushes grafted onto a nanosphere with its radius comparable to the size of polymers is investigated by numerical implementation of the self-consistent field theory. The idea is to embed the sphere within a larger cubic computational cell and use a "masking" technique to treat the spherical boundary. The partial differential equations for the chain pro...

The Hokkaido salamander (Hynobius retardatus) is endemic to Hokkaido Island, Japan, and shows intriguing flexible phenotypic plasticity and regional morphological diversity. However, to date, allozymes and partial mitochondria DNA sequences have provided only an outline of its demographic histories and the pattern of its genetic diversification. To understand the finer details of the population...

Island populations have been extensively used as model systems in ecology, biogeography, conservation and evolutionary biology, owing to the several simplifying assumptions that they allow. Nevertheless, recent findings from intra-island phylogeographic studies are casting doubts on the generality of some of these underlying assumptions. We investigated the phylogeography, historical demography...

INTERISLAND VARIABILITY OF DUNE PLANT COMMUNITY STRUCTURE ON VIRGINIA’S BARRIER ISLANDS Justin K. Shafer Old Dominion University, 2010 Director: Dr. Frank P. Day The barrier islands of the Virginia Coast Reserve LTER site provide an opportunity to study interisland variability of dune plant communities. My research focused on the variation in biomass and diversity of communities among islands a...
