Machine Learning and Optimization Applications in Agriculture

Creator:: Molotkov, Alexander
Abstract:: The ever-increasing global population presents looming problems for the field of agriculture. Global food demand will, at some point, increase to the point where there is not enough crop-ready land to keep up. This creates an additional incentive, other than economics, for growers to increase their yield-per-acre and make sure...

Adaptive Learning Module for Introduction to Materials Science

Creator:: Nigon, Nutnicha
Abstract:: There is a growing need for individualized instructional designs in 4-year institutions due to: 1) growing undergraduate enrollment trends across the U.S., 2) broader diversity in students backgrounds, and 3) the growing prevalence of asynchronous remote learning. With the growth in computer technology in education, tools such as adaptive intelligent...

A taxonomy of biomolecular features

Creator:: North, Jacob L.
Abstract:: The scientific method applies hypothesis testing to material samples through experimentation, measurement, and data analysis, which produce representations—or features—that describe phenomena of interest. Biomolecular features come in numerous forms such as values, matrices, graphs, three-dimensional structures, trajectories, and molecular surfaces. Researchers have tested thousands of features related to protein molecules...

Automated and Accurate Estimation of Gene Family Abundance from Shotgun Metagenomes

Creator:: Nayfach, Stephen, Bradley, Patrick H., Wyman, Stacia K., Laurent, Timothy J., Williams, Alex, Eisen, Jonathan A., Pollard, Katherine S., and Sharpton, Thomas J.
Abstract:: Shotgun metagenomic DNA sequencing is a widely applicable tool for characterizing the functions that are encoded by microbial communities. Several bioinformatic tools can be used to functionally annotate metagenomes, allowing researchers to draw inferences about the functional potential of the community and to identify putative functional biomarkers. However, little is...

Simulation of Heat Transfer Through Soil for the Investigation of Wildfire Impacts on Buried Utilities

Creator:: Richter, Edward G.
Abstract:: Wildland urban interface (WUI) communities in the Western United States have recently dealt with historic and devastating wildfires year after year. The fires have cost tens of billions in damage, burned tens of thousands of structures, displaced thousands of residents, and killed over one hundred people. The 2017 Tubbs fire...

Elevated CO2 may alter pheromonal communication in Helicoverpa armigera (Lepidoptera: Noctuidae)

Creator:: Choi, Kyung San, Ahn, Seung-Joon, Kim, Su Bin, Ahn, Jeong Joon, Jung, Bong Nam, Go, Sang Wook, and Kim, Dong-Soon
Abstract:: Carbon dioxide (CO2) as a greenhouse gas has been increasing in recent decades. Because an elevated atmospheric CO2 influences insect physiology and behaviour, we hypothesize that pheromone-mediated communication in the moth is affected by an increased CO2 level. We test the behavioural responses of male Helicoverpa armigera to sex pheromone...

Effects of age and military service on memory and cognitive flexibility in a virtual Morris water maze task

Creator:: Mollusky, Adina J.
Abstract:: This study applied a virtual version of the Morris water maze (vMWM) task to an examination of age-related differences between younger and older participants, and the impact of prior military service in older men on spatial memory and cognitive flexibility. Participants performed the Logical Memory task that included immediate and...

Discrete-Event Simulation of Ground-Based Timber Harvesting Operations

Creator:: She, Ji, Chung, Woodam, and Kim, David
Abstract:: Operational studies are necessary to support production and management decisions of forest industries. A time study (TS) approach is widely used in timber harvesting operations to understand the performance of individual harvesting machines as well as the entire system. However, several limitations of the TS approach include the use of...

Genomic signatures of mitonuclear coevolution across populations of Tigriopus californicus

Creator:: Barreto, Felipe S., Watson, Eric T., Lima, Thiago G., Willett, Christopher S., Edmands, Suzanne, Li, Weizhong, and Burton, Ronald S.
Abstract:: The copepod Tigriopus californicus shows extensive population divergence and is becoming a model for understanding allopatric differentiation and the early stages of speciation. Here, we report a high-quality reference genome for one population (similar to 190 megabases across 12 scaffolds, and similar to 15,500 protein-coding genes). Comparison with other arthropods...

Fabrication and low-temperature measurement of quantum devices

Creator:: Nichols, Dublin M.
Abstract:: Since the advent of graphene, research on 2D materials has exploded. Countless experiments have uncovered novel properties that emerge when different layered crystals are cleaved down to only a few atomic layers in thickness. The most popular of these non-graphene 2D materials is MoS2, a semiconductor which has been of...
