The clover seed weevil, Tychius picirostris Fabricius (Coleoptera: Curculionidae), is a major pest in Oregon white clover seed crops. Reliance on synthetic pyrethroid insecticides and limited availability of diverse modes of action (MoAs) has increased insecticide resistance selection in regional T. picirostris populations, emphasizing the need to evaluate novel chemistries...
This study aimed to evaluate how the adolescent and young adult (AYA) cancer community utilized Twitter to discuss the financial challenges of oncofertility care and to advocate for change. Tweets related to oncofertility and finances (n = 166), collected over a 12-week time period encompassing AYA Cancer Awareness Week, were...
Given a Euclidean triangle, a sequence of nested triangles is obtained by repeating a specific geometric construction. Two well-known sequences of Euclidean triangles are generalized into hyperbolic and spherical geometries.
While it remains uncertain whether excursions in the stable carbon isotopic composition of Ediacaran marine carbonate (δ13Ccarb) represent globally synchronous events (or a direct measure of ocean carbon cycling), the absence of widely distributed and readily preservable fauna, and the presence of several iconic carbon isotope excursions (CIEs), has sustained...
Wire arc-directed energy deposition (WA-DED) is a promising additive manufacturing (AM) technique for building large, complex near-net-shape parts, combining high deposition rates and fully dense builds. The goal of this study was to explore the advantages of WA-DED for local property optimization by joining a high-strength nickel-based alloy with a...
Increasing summer temperatures and higher probabilities of extreme heat events have led to concerns about tree damage and mortality. However, insufficient attention has been given to conditions leading to heat-related regeneration failures in temperate forests. To address this managers need to understand how microclimate varies under a range of overstory...
A structured decision making (SDM) approach can help evaluate tradeoffs between conservation and human-benefit objectives by fostering communication and knowledge transfer among stakeholders, decision makers, and the public. However, the process is iterative and completing the full process may take years to accomplish. It can be difficult to initiate an...
Suillus (order Boletales) is a diverse genus of, epigeous, mushroom-forming fungi native to temperate forests across the Northern Hemisphere; however, some species are also present in areas where Pinaceae has been introduced in the Southern Hemisphere. Unlike the closely related genus Rhizopogon, there are no described hypogeous, sequestrate species of...
We report electron diffraction results of xenon clusters formed in superfluid helium droplets, with droplet sizes in the range of 105 – 106 atoms/droplet, and xenon clusters from a few to a few hundred atoms. Under four different experimental conditions, the diffraction profiles can be fitted using four atom pairs...
Herein, we report the synthesis of a modular family of novel bimetallic tetraamidodiamine (tada) ligands, Li4-R-tada (R = Me3Si, t BuMe2Si, and i Pr3Si). These silylamido ligands display two distinct binding pockets whose steric profiles can be easily tuned by choice of the substituents on silicon We also show that...
