The (±) 8,9:13,14-diseco-norestradiol, a large ring hormone
analog, and its related derivatives, were prepared by a ring expansion
approach. The key step of this approach is the establishment of the
benzocyclododecenone system via the Caubere reaction. This step
not only provides a favorable ring size, it also sets the necessary...
The Gulf of Alaska (GOA) is home to the most productive fisheries in the world. In 2019, 2.2 million metric tons of fish were shipped from Alaska to destinations all over the world (NOAA Fisheries, 2019). From 2014-2016 and, more recently, in 2019 the largest heatwaves in recorded history caused...

Hydrokinetic turbines are an emerging form of renewable energy generation. Although similar to wind turbines, hydrokinetic systems incur extra costs and face constraints in available footprint. SiC power semiconductors within the required power electronics improve the performance. With higher switching afforded by SiC devices, the footprint of passive components for...
The increased demand for building materials that are friendly to the environment, along with the latest advances in wood science and technology, which exploit the fiber orientation of wood, resulted in composite wood materials known as mass-timber products. To understand the effects the wood fiber orientation has on the dynamic...
The integration of power electronics within the energy and transportation sectors enlists a demand for the rapid development of energy-efficient electrical systems. While model-based design and physics-based simulations are effective ways to handle the multi-disciplinary and multi-objective (MO) design of these complex systems, design exploration remains a time-consuming procedure. A...
Modeling tire-snow interaction is important in designing effective snow tires, which directly affects road safety during wintry weather. Unfortunately, tires have complex tread designs and the physical properties of snow have not been characterized. We employ the Material Point Method (MPM) for simulating a material that mimics the fracturing and...
Stephen Biko was a black leader in South Africa who
died in police custody on September 12, 1977. Biko's death
echoed within the Republic of South Africa and around the
world, showing that racial tensions in that country were
severe. At his death he was a hero to the black...
This study evaluates the distributional impacts of an alternative public roads finance method, a road usage charge (RUC) fee, on lower income households and rural households in Oregon. While previous research has relied on the 2001 and 2009 National Household Travel Survey (NHTS), this research will uses the 2011-2013 Oregon...
Time-domain data conversion has recently drawn increased research attention for its highly digital nature in favor of process technology scaling. Also, as the time information being carried by binary voltage, time-domain operation is much less sensitive to voltage noise compared to conventional voltage domain operation. However, for analog-to-digital converter (ADC)...
