| 261 |  | Gerig, Guido | Early postnatal development of corpus callosum and corticospinal white matter assessed with quantitative tractography | BACKGROUND AND PURPOSE: The early postnatal period is perhaps the most dynamic phase of white matter development. We hypothesized that the early postnatal development of the corpus callosum and corticospinal tracts could be studied in unsedated healthy neonates by using novel approaches to diffusion... | 2007-01-01 | |
| 262 |  | Regehr, John | Efficient memory safety for TinyOS | Reliable sensor network software is difficult to create: applications are concurrent and distributed, hardware-based memory protection is unavailable, and severe resource constraints necessitate the use of unsafe, low-level languages. Our work improves this situation by providing efficient memory an... | 2007-01-01 | |
| 263 |  | Jarrard, Richard D. | Exceptionally preserved jellyfishes from the Middle Cambrian | Cnidarians represent an early diverging animal group and thus insight into their origin and diversification is key to understanding metazoan evolution. Further, cnidarian jellyfish comprise an important component of modern marine planktonic ecosystems. Here we report on exceptionally preserved cnida... | Jellyfishes; metazoan evolution; jellyfish fossils; marjum formation; Utah; middle cambrian | 2007-10-31 |
| 264 |  | Garrett, Timothy J. | Gains in economic energy efficiency as the impetus for increasing atmospheric carbon dioxide | Growth of anthropogenic carbon dioxide (CO2) emissions is frequently diagnosed as a product of population, per capita economic production, the energy intensity of economic production (or inverse of its energy efficiency), and the carbon intensity of energy. This paper introduces an alternative, p... | carbon dioxide, energy efficiency, economics | 2007-12-17 |
| 265 |  | Sanchez, Thomas W. | Growth and change Florida style: 1970 to 2000 | In response to development patterns leading to what may be termed "urban sprawl," several local, regional, and state governments in the United States have embarked on growth management or urban containment strategies. These strategies typically aim to synchronize key public facilities with urban dev... | 2007-01-01 | |
| 266 |  | Sokolsky, Pierre | Highest energy cosmic rays and results from the HiRes experiment | The status of the field of ultrahigh energy cosmic ray physics is summarized, from the point of view of the latest results of the High Resolution Fly's Eye (HiRes) Experiment.
