Matthew B. Sullivan; MASSACHUSETTS INST OF TECH CAMBRIDGE
|
 | The marine cyanobacteria Prochiorococcus and Synechococcus are numerically dominant primary producers in the oceans. Each genera consists of multiple physiologically and genetically distinct groups (termed "ecotypes" in Prochiorococcus). Cyanobacterial viruses (cyanophages) that infect Synechococcus are abundant (to 104.106 phage ml.I) in the oceans and calculations suggest that they play a small but significant role in host mortality. Cyanophages are also thought to shape their host populations through regulation of sub-populations ... |

We compare the extended domain-model to the four-layered architecture for open computational systems (OCS). Implementations of (1) the interaction platform Service oriented layered architecture for communicating entities (SOLACE) and (2) the Distributed interaction system for complex entity relation networks (DISCERN) are introduced.

| Appropriate interactions between breast cells and the ECM via alpha2beta1 integrin help to establish normal cellular structure and differentiation. During transformation to a carcinoma, these normal interactions with the ECM are profoundly altered, resulting in cells that lose their specialization and lose control of their growth. Ultimately, these cells become invasive, and then migrate through the connective tissue environment to form distant metastases. We have previously found that Ack-l tyrosine ... |

| This research analyzes the regulation of ischemic tolerance in hibernating thirteen-lined ground squirrels (Spermophilus tridecemlineatus). Hibernation is studied because it represents a unique state of reversible suspended animation associated with tolerance to an otherwise lethal reduction of core body temperature and metabolism. An integral aspect of hibernation is the profound decrease of cerebral perfusion without neurological damage. As such, hibernation serves as a model for studying natural tolerance to brain ... |

| As colored dissolved organic matter in seawater absorbs UV solar radiation, a variety of simple chemical species are produced, including carbon monoxide (CO). The ocean surface water is saturated with respect to CO, and is thus a source of CO to the atmosphere. CO reacts with and removes free-radical compounds, and may itself contribute to the greenhouse gas content of the atmosphere. An important sink for CO in seawater is ... |

| Hydrellia pakistanae, a biological control agent of hydrilla, was first introduced into Lake Seminole in 1990. Impact by this species remained low until 1998 when large numbers of individuals and associated impact, as well as increases in native plant diversity, were observed in several locations. In 1999, large-scale reductions in hydrilla were observed throughout many areas of the lake. These changes were correlated with changes in insect numbers where large ... |
