Severe wildfires are increasing in the western United States, impacting vegetation structure, and in turn, forest regeneration conditions. These wildfires are also raising a substantial amount of scientific and management concern regarding the resilience of forested ecosystems, or the ability of the ecosystem to return to a pre-fire condition. This...
Black male student-athletes in revenue-producing sports encounter multiple stressors at predominantly White institutions (PWI). These stressors can include identity conflicts, role confusion, feelings of exploitation as revenue producers, academic imposter syndrome, heavy workloads, and racial microaggressions. This study explores how Black male student-athletes in revenue-producing sports define their roles within...
Mosses (Phylum Bryophyta) are widely considered to be among the most ancient groups of land plants (embryophytes) and they are the second most speciose embryophyte phylum with ~13,000 extant species. Despite their diversity and antiquity, mosses have a limited fossil record, which primarily consists of gametophytes entombed in Cenozoic amber....
Climate model simulations and paleoclimate proxies are two tools that enable an understanding of the climate history of the Earth. When utilized together, they form a powerful paradigm for understanding past changes. Proxies are the only physical link to the past conditions on Earth, and models “fill in the gaps”...
Grapevine red blotch virus (GRBV) is a single-stranded DNA virus that causes grapevine red blotch disease (GRBD). Symptoms of GRBD include red discoloring of leaf margins and red veins on the underside of the leaves. GRBD affects the plant's metabolism and photosynthetic pathways, and disrupts carbon translocation and chlorophyll concentrations....
Chlorinated solvents are a class of widespread groundwater contaminants that are toxic, carcinogenic, and difficult to remediate at low concentrations. 1,4-dioxane, a suspected carcinogen, is often a co-contaminant found in mixtures of chlorinated solvent plumes. In-situ bioremediation methods of degrading these chemicals through aerobic cometabolism have shown promise. Permeable Reactive...
NAND flash based solid state drives (SSDs) require out-of-place updating due to the characteristics of flash memories. In addition, due to the mismatched granularity between read/write and erase operations, a cleaning policy involving garbage collection and wear leveling has to perform data migration incurring high overhead. Another challenge is that...
Integrated Distributed Electric Augmented Lift (IDEAL) applies upper-surface blowing in a novel way using an array of electric ducted fans (EDFs) to achieve electric short take-off and landing to meet the growing need for urban air transportation. Additional research on the use of vortex generators (VGs) to reduce flow separation...
A growing body of research has connected bullying victimization to a number of risk factors in adolescents, including substance use. The current study utilizes Agnew’s revised strain theory as a theoretical framework to examine this relationship, as well as patterns of substance use across gender, race, and mental health status....
Previous research has shown that traveling in a work zone involves a higher risk of crashing compared to normal (non-work zone) driving conditions. Research further suggests that the severity of work zone crashes is greater on average than non-work zone crashes. The period of time in which the traffic control...
