Phase I has proven that the current setup achieves better than 8mm spatial resolution for 2.2MeV prompt gammas. However, 1mm spatial resolution presents a significant challenge for the current setup due in part to limited timing resolution and count rate. A new analog ASIC will be developed to replace the current analog ASIC that will have better timing resolution and deliver higher count rates. I ...

Methods for interconversion between cell types (cellular reprogramming) are currently discovered through resource intensive trial and error. Experiments may test a multitude of transcription factors to identify correct combinations that influence cell fate. In addition, reprogramming approaches commonly use stem cell intermediates such as induced pluripotent stem cells (iPSCs), which are generated ...

Many demanding photonic applications require high-efficiency and high-speed photon counting. For these applications, superconducting nanowire photon detectors have capabilities that exceed those of conventional single-photon counting devices such as vacuum tubes and semiconductor devices. Comparatively, nanowire detectors exhibit higher infrared sensitivity, higher speed, lower intrinsic noise, an ...

THE PRESENT PROGRAM HAS THREE TECHNICAL OBJECTIVES. THE FIRST IS TO CONSTRUCT A COMPUTER CONTROLLED VERSION OF A CONFIGURABLE OPTICAL SUPERCLASSIFIER THAT IS CAPABLE OF ACCEPTING A SYSTOLIC STREAM OF INPUT DATA. THE NEXT MAJOR OBJECTIVE OF THIS PROPOSAL IS TO DEVELOP A DETAILED DESCRIPTION OF THE BUS STRUCTURE THAT WILL BE REQUIRED TO FEED DATA INTO THE OPTICAL SUPERCLASSIFIER AT RATES THAT ARE CO ...
