OBJECTIVES/SPECIFIC AIMS: To create a searchable public registry of all Quality Improvement (QI) projects. To incentivize the medical professionals at UF Health to initiate quality improvement projects by reducing startup burden and providing a path to publishing results. To reduce the review effort performed by the internal review board on projects that are quality improvement Versus research. To foster publication of completed quality improvement projects. To assist the UF Health Sebastian Ferrero Office of Clinical Quality & Patient Safety in managing quality improvement across the hospital system. METHODS/STUDY POPULATION: This project used a variant of the spiral software development model and principles from the ADDIE instructional design process for the creation of a registry that is web based. To understand the current registration process and management of quality projects in the UF Health system a needs assessment was performed with the UF Health Sebastian Ferrero Office of Clinical Quality & Patient Safety to gather project requirements. Biweekly meetings were held between the Quality Improvement office and the Clinical and Translational Science – Informatics and Technology teams during the entire project. Our primary goal was to collect just enough information to answer the basic questions of who is doing which QI project, what department are they from, what are the most basic details about the type of project and who is involved. We also wanted to create incentive in the user group to try to find an existing project to join or to commit the details of their proposed new project to a data registry for others to find to reduce the amount of duplicate QI projects. We created a series of design templates for further customization and feature discovery. We then proceed with the development of the registry using a Python web development framework called Django, which is a technology that powers Pinterest and the Washington Post Web sites. The application is broken down into 2 main components (i) data input, where information is collected from clinical staff, Nurses, Pharmacists, Residents, and Doctors on what quality improvement projects they intend to complete and (ii) project registry, where completed or “registered” projects can be viewed and searched publicly. The registry consists of a quality investigator profile that lists contact information, expertise, and areas of interest. A dashboard allows for the creation and review of quality improvement projects. A search function enables certain quality project details to be publicly accessible to encourage collaboration. We developed the Registry Matching Algorithm which is based on the Jaccard similarity coefficient that uses quality project features to find similar quality projects. The algorithm allows for quality investigators to find existing or previous quality improvement projects to encourage collaboration and to reduce repeat projects. We also developed the QIPR Approver Algorithm that guides the investigator through a series of questions that allows an appropriate quality project to get approved to start without the need for human intervention. RESULTS/ANTICIPATED RESULTS: A product of this project is an open source software package that is freely available on GitHub for distribution to other health systems under the Apache 2.0 open source license. Adoption of the Quality Improvement Project Registry and promotion of it to the intended audience are important factors for the success of this registry. Thanks goes to the UW-Madison and their QI/Program Evaluation Self-Certification Tool (https://uwmadison.co1.qualtrics.com/SE/?SID=SV_3lVeNuKe8FhKc73) used as example and inspiration for this project. DISCUSSION/SIGNIFICANCE OF IMPACT: This registry was created to help understand the impact of improved management of quality projects in a hospital system. The ultimate result will be to reduce time to approve quality improvement projects, increase collaboration across the UF Health Hospital system, reduce redundancy of quality improvement projects and translate more projects into publications.

The AURORA KrF laser at Los Alamos became operational in August 1989. AURORA is the first integrated system for demonstrating the capability of a KrF laser to perform target physics experiments for inertial confinement fusion (ICF) and is currently configured as a 5-kJ, 5-ns, 96-beam device. Both laser physics and ICF target physics experiments have been performed over the last year. Of the four major amplifiers in the AURORA laser system, one performed better than expected, one performed about as expected, and two performed below expectations. The causes of the variability in the amplifier performance are now well enough understood that this information can be used to improve the detailed design of the NIKE laser currently under construction at the Naval Research Laboratory. design of the NIKE laser currently under construction at the Naval Research Laboratory. High-dynamic-range pulse shapes have been propagated with minimal distortion through the AURORA amplifier chain, verifying theoretical predictions. Target physics experiments have been performed with intensities greater than 100 TW/cm2, pulse lengths ranging from 2–7 ns, and spot-size diameters from 500–1100 µm. The analysis of this first-generation kJ-class KrF laser target physics facility identified the strengths and weaknesses of KrF lasers for ICF applications. Detailed measurements of amplifier performance led to a better understanding of issues for KrF laser-fusion systems, and design studies for future KrF lasers for ICF applications incorporate improvements based in part on AURORA experience.

This paper reviews the reliability results for the gallium nitride on silicon (GaN-on-Si) technologies for commercial and military communications markets. Two technology platforms have been qualified for volume production: one consisting of discrete heterostructure field effect transistors (HFETs) and the other consisting of HFETs integrated with passive components to form monolithic microwave integrated circuits (MMICs). The technology platform qualifications for volume production have been achieved through intrinsic reliability tests on the active and passive device elements as well as extrinsic reliability tests at the product level. This paper presents reliability results on accelerated life test (ALT), high temperature operating life under DC and RF stress (DC/RF-HTOL), electrostatic discharge (ESD), ramped voltage breakdown, electromigration, temperature cycling, robustness under voltage standing wave ratio (VSWR) mismatch conditions, and diode stability. Degradation and breakdown mechanisms are discussed in relation to material properties reliability. The results show that the HFET and MMIC technology platforms display reliable performance for 20 year product lifetime at worst case operating conditions.

In the last decade, GaN-on-Si has progressed from fundamental crystal growth studies to product realization and reliability demonstration. GaN-on-Si HEMTs addressing cellular, WiMAX, and broadband RF applications are now commercially available and offer GaN performance attributes in a cost-competitive platform. This presentation will briefly describe the underlying GaN-on-Si material, process, and packaging technology, then focus primarily on performance of these products in both commercial and military applications.
All Nitronex NRF1 GaN-on-Si products are grown by MOCVD on 100 mm float-zone Si (111) substrates. A proprietary, strain-compensating (Al,Ga)N transition layer and an amorphous SixAl1-xNy nucleation layer are employed to accommodate lattice and thermal expansion mismatch between the substrate and the epilayers. The wafer fabrication process employs Ti/Al-based ohmic contacts, ion implant device isolation, 0.5 um dielectrically-defined gates, gold airbridge interconnects, and through-wafer source vias. Typical inline DC parametrics include 2DEG sheet resistance of 490 ohms/sq., on-resistance of 3 ohm-mm, peak drain current density of 830 mA/mm, and breakdown voltage of >100V. Packaging solutions include traditional LDMOS-style air cavity outlines with thermally-enhanced flange materials and low-cost plastic SOIC.
A family of devices addressing emerging OFDM-based applications such as WiMAX has been developed. WiMAX amplifiers require several watts of linear output power with frequency band allocations ranging from 2.3 to 5.8 GHz and instantaneous bandwidth up to ∼15%. Translated to the transistor level, this implies simultaneous high frequency and high voltage capability – attributes well-suited to the inherent advantages of GaN-based devices. The flagship product in this family is NPT25100, delivering 125W of peak envelope power at 2.5 GHz. Under 2.5 GHz single-carrier OFDM modulation and 10 MHz channel bandwidth, this device produces 10W linear power at 2.0% EVM with 16.5dB associated gain and 26% drain efficiency. The excellent bandwidth of NRF1 devices enables the same device to operate at cellular frequencies from 2.11 - 2.17 GHz, producing >20W average power at an adjacent channel power ratio of -35 dBc.
Primary military insertion opportunities include communications (e.g., JTRS - Joint Tactical Radio System) and electronic warfare (e.g., jammers). For EW applications, broadband operation reduces system-level component count and decreases weight / footprint. A family of 48V GaN-on-Si broadband HEMTs has been developed to deliver power levels from 40W - 180W in a compact package. In the highest power case, packaged “power density” (defined as peak output power divided by package volume) reaches ∼650 W/cm3. These power levels – in an outline suitable for highly portable systems – enable improved communications transmit distance and extend the umbrella size of electronic protection units.
