Estimating Traffic Volume on Wyoming Low Volume Roads Using Linear and Logistic Regression Methods

open access: yes, 2016
Traffic volume is an important parameter in most transportation planning applications. Low volume roads make up about 69% of road miles in the United States.

Modular Lipoprotein Toxins Transferred by Outer Membrane Exchange Target Discrete Cell Entry Pathways

open access: yesmBio, 2021
Many bacterial species use diverse systems to deliver bacteriocins or toxins to neighboring competing cells. These systems are often selective in targeting cells that are related to themselves and therefore compete in the same niches for resources.

Ecosystem resilience is evident 17 years after fire in Wyoming big sagebrush ecosystems

open access: yes, 2016
Recent policy has focused on prevention of wildfire in the sagebrush steppe in an effort to protect habitat for the greater sage grouse (Centrocercus urophasianus).

Functional and structural specific roles of activity-driven BDNF within circuits formed by single spiny stellate neurons of the barrel cortex

open access: yesFrontiers in Cellular Neuroscience, 2014
Brain derived neurotrophic factor (BDNF) plays key roles in several neurodevelopmental disorders and actions of pharmacological treatments. However it is uncealr how specific BDNF’s effects are on diffeerent circuit components.

Borohydride oxidation electrocatalysis at individual, shape‐controlled Au nanoparticles

open access: yesElectrochemical Science Advances, 2022
Nanostructured materials are frequently employed as active components in electrochemical devices for energy conversion and storage. Unfortunately, the complexity of nanostructured materials, which can exhibit significant heterogeneities in morphology and/

Whole-Genome Duplication and Host Genotype Affect Rhizosphere Microbial Communities

open access: yesmSystems, 2022
The composition of microbial communities found in association with plants is influenced by host phenotype and genotype. However, the ways in which specific genetic architectures of host plants shape microbiomes are unknown.

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

open access: yesAdvanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

open access: yesAdvanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Spatiotemporal predictions of the alternative prey hypothesis: Predator habitat use during decreasing prey abundance

open access: yesEcosphere, 2023
The alternative prey hypothesis supposes that predators supported by a primary prey species will shift to consume alternative prey during a decrease in primary prey abundance.

Factors associated with crash severity on rural roadways in Wyoming

open access: yes, 2016
The ability to identify risk factors associated with crashes is critical to determine appropriate countermeasures for improving roadway safety. Many studies have identified risk factors for urban systems and intersections, but few have addressed crashes ...
