Previous studies have demonstrated that light detection and ranging (LiDAR)-derived variables can be used to model forest yield variables, such as biomass, volume, and number of stems. However, the next step is underrepresented in the literature: estimation of forest yield with appropriate confidence intervals. It is of great importance that...
This paper empirically examines the effects of population aging on international trade using a cross-country panel data set for a select group of 22 OECD countries. Other recent studies have examined the effects of population age on other economic variables such as growth, savings, and investment but none till now...
Oregon’s gasoline tax no longer serves as an economically efficient revenue source due to increasing fuel efficiency and the emergence of alternative fuels. In response to this problem, the Oregon Department of Transportation is exploring alternatives to the gasoline tax. Among the most promising alternatives is a flat-rate vehicle mile...
Silicon photonics has rapidly become one of the most promising photonic integration platforms. Especially, microring resonator (MRR) plays a pivotal role in silicon photonics and has been widely used for electro-optic (E-O) modulators and wavelength filters due to its small footprint, low energy consumption, and high quality factor (Q-factor). Recently,...
Oxidative stress occurs when the balance between reactive oxygen species and antioxidant defense mechanisms in the body becomes tipped heavily in favor of the reactive oxygen species. Reactive oxygen species can be present in excess due to elevated O2 levels, radiation, infection, smoking, or even excessive exercise. It is also...
Genetic and morphological characteristics of an architectural mutant in common beans were studied. The mutant had shiny, dark green leaves, overlapping leaflets, short petioles and a reproductive terminal bud even though the line did not carry the fin gene. Branching was nearly absent resulting in a single stem vine. This...
Past research on Head Start has focused on child outcomes, yet Head Start services also target the behaviors of parents. Using data from the Fragile Families and Child Well-being Study (FFCW), the current study examined the effect of Head Start on mother (n = 3,575) and father (n = 1,812)...
The reactions of cyclodeca-1, 2, 5, 8-tetraene with mercuric salts
in solvents of varying nucleophilicity are described. Instead of forming
the usual oxymercuration products reported for reactions of olefins
and allenes with mercuric salts, the major products obtained in the
present cases result from the initial electrophilic addition of the...
There are record numbers of immigrants in the U.S., with no indication of declining in the future. Social debates surrounding issues such as immigration are fragile. It is critical that research and knowledge put out to the public and used by policy makers to create or reform immigration legislation must...
