 | Annular field reversed configuration (AFRC) devices form annular plasma toroids between a pair of concentric cylindrical coils. This plasmoid remains detached from the external magnetic _field so that it can be ejected from the coils, making AFRCs viable pulsed inductive plasma accelerators. Though numerous formation studies on AFRCs are available, no successful translation studies have been published. Michigan Technological University, in conjunction with the Air Force Research Laboratory, is investigating ... |

|
| Molecular targeting approaches have tremendous potential for early-detection because they rely on elucidation of abnormal gene-expression, rather than on discovery of retarded anatomical changes inflicted by growing tumors upon their microenvironment. We investigated whether fluorescence molecular tomography (FMT) could be used to detect breast cancer at its earliest stages via the detection of injected, protease-activatable molecular probes. We have successfully completed all goals and achieved the three major aims of ... |

Kimberly Hamad-Schifferli; MASSACHUSETTS INST OF TECH CAMBRIDGE
|
 | The goal of this proposal is to develop the use of a nanoscale interface to protein translation machinery to control translation. External magnetic fields excite the nanoscale interface and thus switch on translation of a protein. This technique would enable time-specific control of protein expression, and would enable new techniques in disease diagnosis and therapy. These objectives are in line with the original proposal. |

| The transcription factor, C/EBPbeta, is critical for growth and differrentation of the mammary gland. Three forms of C/EBPbeta are expressed in cells through alternative translation of the C/EBPbeta mRNA. C/EBPbeta- 1 and -2 activate transcription; C/EBPbeta-2 is a truncated form that represses transcription. Based upon their distinct expression patterns in normal and transformed cells as well as functional studies, we propose that C/EBPbeta-l and -3 (or both) will be potent ... |

| This paper describes a novel approach for handling translation divergences in a Generation- Heavy Hybrid Machine Translation (GHMT) system. The approach depends on the existence of rich target language resources such as word lexical semantics, including in- formation about categorical variations and subcategorization frames. These resources are used to generate multiple structural variations from a target-glossed lexico-syntactic representation of the source language sentence. The multiple structural variations account for different ... |
