|
 | In this funding period, the P.I. investigated nonlinear light propagation in one- and two-dimensional optically-induced photonic lattices both theoretically and experimentally. Photonic lattices in these works were created by optical induction and were highly tunable in real time, thus they provided a convenient medium to study novel physical phenomena of light propagation in periodic and quasiperiodic media. P.I. discovered many new types of nonlinear localized modes (optical solitons) in photonic ... |

| BT474 xenograft modal was successfully established in our lab. Tumor stroma enriched BT474 modal was tested using BT474 cell lines and human breast fibroblast cell lines. Mixture of BT474 cells and human breast fibroblast cells did not yield a xenograft with sufficient fibroblast component. LCM panning of human tumor specimens was performed with selection on blood vessels. More than 200 monoclones were evaluated for binding. Although clones were identified with ... |

| We developed combined run-time and compile-time analyses for enforcing trace based safety properties in higher order and Object Oriented programs, called trace effect analysis. Traces are the ordered sequence of events generated by programs. A wide variety of interesting language safety mechanisms can be expressed as trace properties, such as access control, resource usage protocols, and context sensitive flow analysis. Consequently, our analyses provide a uniform framework for automatically enforcing ... |

| Platelet Modulation in the Control of Breast Cancer Angiogenesis and Metastasis |

Chris E Holmes; VERMONT UNIV BURLINGTON
|
| Platelets are circulating reservoirs of proteins that both promote and inhibit angiogenesis and metastasis. The release of proteins in the tumor microenvironment can be accomplished by multiple different pathways. We determined the influence of key platelet activation pathways on angiogenesis using an endothelial cell migration assay. We found independent pathways of platelet activation resulted in differential effects on angiogenesis. Activation through the platelet collagen receptor and proteinase activated receptor-4 (PAR4) ... |

| In a region of northeastern Amazonia, we find a species previously of minor importance, Anopheles marajoara, to be the principal malaria vector. In a total of five collections during 1996-97 in three replicated sites near the city of Macapa, Amapa state, this species occurs in much greater abundance compared with the presumed vector Anopheles darlingi. Also, a significantly higher proportion of An. marajoara is infected with malaria parasites, determined by ... |

| Performance and reliability are major concerns in the design of large disk arrays. Hellerstein et al. pioneered the study of erasure-resilient codes that allow one to reconstruct data without loss in the presence of disk failures. Chee, Colhourn, and Ling used the close connection between erasure- resilient codes and certain combinatorial designs to establish much improved asymptotic and exact existence results for these codes. The design-theoretic approach provided the scientific ... |

One unforeseen difficulty was the essential role that co-dopants played in the simple epitaxial growth of Er doped Si material. Without co-dopants, the Er introduced during growth, segregates to the growth surface and prevents single crystal formation. It was decided to produce films with varying ... |

| Authors:
Jerome F. Fiekers; VERMONT UNIV BURLINGTON
|
| The effects of soman, sarin, and VX were examined on ganglionic transmission through paravertebral sympathetic chain ganglia of the bullfrog, Rana catesbeiana. Low-frequency (0.1 Hz), short (2 sec) and long (10 sec) trains of preganglionic stimulation induced repetitive activity and an irreversible transient depression in the extracellularly recorded compound action potential (CAP) amplitude during the first second of train stimulation following agent exposure. Long stimulus trains of high frequency were ... |

| The concentration-dependent effects of soman were examined on the electrical properties of bullfrog postganglionic sympathetic neurons. Soman depolarizes individual ganglion neurons and reduces the input resistance in about 70% of the neurons studied. In addition, soman produces an increase in neuronal excitability which is (1) not dependent on the membrane potential, (2) reversible with washing, and (3) not caused by an inhibition of the M-current. Soman reduces the duration of ... |

|
| Although ganglionic transmission is one of the primary targets for organophosphorous (OP) and anticholinesterase agents, very little is currently known concerning the electrophysiological and ultrastructural changes at peripheral ganglionic sites induced by their use. The effects of this class of compounds are generally attributed to an accumulation of acetylcholinesterase (ACH) within the synaptic cleft as a consequence of acetylcholinesterase (AChE) inhibition. However, direct effects on both pre- and postsynaptic sites ... |

Despite replacement of blood, fluids and electrolytes, expert surgical care, antibiotics and hkemodialysis the overall mortality has remained high (50-60%). The underlying cause of death is not renal failure now that dialysis is available but the associated hypercatabolic state in which wound healing is available but the associated hypercatabolic state ... |

| Measurements of the fracture energy of debonding between epoxy resin and glass shows that it decreases linearly with time to a low and constant level. As the structural integrity of laminated composites depends on the non- propagation of shear cracks, their usefulness as structures can be related to the decrease of fracture energy to the bonds. Interlaminar shear failures are then directly related to the presence of moisture and are ... |

Preliminary results indicate the existence of an endurancelimit which is approximately 60% of the fracture load. During fatigue testing,there was a 12% increase in both the shear modulus and Young's modulus. Thefracture load also increased about 12%. These two effects may be due to astress induced cross-linking. (Author, ... |
