A Policy Project: Implementing Safe Firearm Storage Legislation in Kentucky
Ensuring the safe storage of firearms in the home is a research-supported method of reducing the incidence of firearm injury and death, specifically unintentional injury and self-harm in the pediatric population. The American Academy of Pediatrics recommends keeping all firearms stored locked, unloaded, and separate from ammunition. While evidence shows that implementing laws regulating the storage of firearms can be effective to reduce morbidity and mortality, the state of Kentucky currently has no such regulations. For this DNP project, John Kingdon’s Multiple Streams Framework was used as a guideline for policy analysis with the intention of identifying opportunities to advocate for legislative action on this issue (2003). A 4-part intervention including participation in the legislative process and grassroots advocacy efforts was completed, as well as partnering with a legislator to introduce new legislation. House Bill 292 “An act Relating to Gun Safety for Children” was introduced in the 2022 Kentucky legislative session. Although this bill did not pass into legislation, advocacy efforts were effective in spreading awareness of the issue to make conditions more favorable for future legislation in Kentucky.

How Does Wind Project Performance Change with Age in the United States?
Wind-plant performance declines with age, and the rate of decline varies between regions. The rate of performance decline is important when determining wind-plant financial viability and expected lifetime generation. We determine the rate of age-related performance decline in the United States wind fleet by evaluating generation records from 917 plants. We find the rate of performance decline to be 0.53%/year for older vintages of plants and 0.17%/year for newer vintages of plants on an energy basis for the first 10 years of operation, which is on the lower end of prior estimates in Europe. Unique to the United States, we find a significant drop in performance by 3.6% after 10 years, as plants lose eligibility for the production tax credit. Certain plant characteristics, such as the ratio of blade length to nameplate capacity, influence the rate of performance decline. These results indicate that the performance decline rate can be partially managed and influenced by policy

Opportunities for and challenges to further reductions in the “specific power” rating of wind turbines installed in the United States
A wind turbine’s “specific power” rating relates its capacity to the swept area of its rotor in terms of Watt per square meter. For a given generator capacity, specific power declines as rotor size increases. In land-rich but capacity-constrained wind power markets, such as the United States, developers have an economic incentive to maximize megawatt-hours per constrained megawatt, and so have favored turbines with ever-lower specific power. To date, this trend toward lower specific power has pushed capacity factors higher while reducing the levelized cost of energy. We employ geospatial levelized cost of energy analysis across the United States to explore whether this trend is likely to continue. We find that under reasonable cost scenarios (i.e. presuming that logistical challenges from very large blades are surmountable), low-specific-power turbines could continue to be in demand going forward. Beyond levelized cost of energy, the boost in market value that low-specific-power turbines provide could become increasingly important as wind penetration grows
Deviations from Matthiessen's Rule for and
We have measured the change in the resistivity of thin films of and upon introducing point defects by electron
irradiation at low temperatures, and we find significant deviations from
Matthiessen's rule. For a fixed irradiation dose, the induced change in
resistivity {\it decreases} with increasing temperature. Moreover, for a fixed
temperature, the increase in resistivity with irradiation is found to be {\it
sublinear}. We suggest that the observed behavior is due to the marked
anisotropic scattering of the electrons together with their relatively short
mean free path (both characteristic of many metallic oxides including cuprates)
which amplify effects related to the Pippard ineffectiveness condition

Annual Report on U.S. Wind Power Installation, Cost, and Performance Trends: 2007 (Revised)
This report focuses on key trends in the U.S. wind power market, with an emphasis on the latest year, and presents a wealth of data, some of which has not historically been mined by wind power analysts
Three-body decay of Be
Three-body correlations for the ground-state decay of the lightest two-proton
emitter Be are studied both theoretically and experimentally. Theoretical
studies are performed in a three-body hyperspherical-harmonics cluster model.
In the experimental studies, the ground state of Be was formed following
the decay of a C beam inelastically excited through
interactions with Be and C targets. Excellent agreement between theory and
experiment is obtained demonstrating the existence of complicated correlation
patterns which can elucidate the structure of Be and, possibly, of the
A=6 isobar.Comment: 17 pages, 21 figures, 5 table
System-Level Testing of the Advanced Stirling Radioisotope Generator Engineering Hardware
To support future NASA deep space missions, a radioisotope power system utilizing Stirling power conversion technology was under development. This development effort was performed under the joint sponsorship of the Department of Energy and NASA, until its termination at the end of 2013 due to budget constraints. The higher conversion efficiency of the Stirling cycle compared with that of the Radioisotope Thermoelectric Generators (RTGs) used in previous missions (Viking, Pioneer, Voyager, Galileo, Ulysses, Cassini, Pluto New Horizons and Mars Science Laboratory) offers the advantage of a four-fold reduction in Pu-238 fuel, thereby extending its limited domestic supply. As part of closeout activities, system-level testing of flight-like Advanced Stirling Convertors (ASCs) with a flight-like ASC Controller Unit (ACU) was performed in February 2014. This hardware is the most representative of the flight design tested to date. The test fully demonstrates the following ACU and system functionality: system startup; ASC control and operation at nominal and worst-case operating conditions; power rectification; DC output power management throughout nominal and out-of-range host voltage levels; ACU fault management, and system command / telemetry via MIL-STD 1553 bus. This testing shows the viability of such a system for future deep space missions and bolsters confidence in the maturity of the flight design
Magnetic susceptibility of insulators from first principles
We present an {\it ab initio} approach for the computation of the magnetic
susceptibility of insulators. The approach is applied to compute
in diamond and in solid neon using density functional theory in the local
density approximation, obtaining good agreement with experimental data. In
solid neon, we predict an observable dependence of upon pressure.Comment: Revtex, to appear in Physical Review Lette
