NADH is an optical metabolic indicator– a molecule we can use to monitor metabolism– because it is naturally occurring, it is involved in energy metabolism, and it fluoresces. NADH fluorescence depends on which protein to which it is bound. UV-excited autofluorescence spectroscopy is a technique used to measure the emission spectrum of excited biological substances. […]
C52: Effects on travel velocity in wild woolly monkeys (Lagothrix lagotricha poeppigii) at Tiputini Biodiversity Station, Ecuador
Travel is a crucial function animals use to fulfill needs including food acquisition, reproduction, and finding sleeping sites. Given the cognitive demands of locating preferred resources both spatially and temporally across a landscape, studies on naturalistic travel paths may help us better understand the cognitive capacities and spatial memory of the species in question. In […]
C34: Instream Boulder Effects on Substrate Spawning Fish Species
Adequate spawning habitats are crucial for the success and productivity of fish populations. Instream boulders can create favorable spawning sites by creating depressions or riffles where fish can deposit their eggs. Habitat restoration projects are put in place to offset the destruction of spawning grounds and improve habitat functionality. Our research aims to provide insight […]
C35: Early postnatal voluntary wheel running impacts on growth rate, grip strength, muscle mass, and body composition
Introduction and Purpose Physical activity (PA) is a vital behavior to maximize health. Less is understood regarding the impact of physical activity opportunities in key stages of skeletal muscle development, such as the time frame between weaning and sexual maturation. We propose that, in opposition to the negative effects of disuse, exposure to voluntary wheel […]
C36: Robust Storage of Optical Information in Atomic Vapor for Creating a Quantum Memory
Our project is about converting Gaussian beams into Laguerre-Gaussian (LG) and Bessel beams in order to explore robust storage of optical information in atomic vapor. For this, we require the use of a Spiral Phase Plate (SPP) and an Axicon, respectively, to create the aforementioned beams. This entails working with advanced optics and acousto-optic modulators […]
C37: Brownian ratchets: Nano-devices that make randomly diffusing atoms undergo directed motion without applying any net force
Brownian ratchets are nanodevices capable of extracting useful work from environmental noise to create directed motion of particles in the absence of a net force. Research in this area is inspired by biomolecular motors that power the processes of life by utilizing random fluctuations in their environment. These naturally occurring nanodevices are several orders of […]
C70: Effects of Invasive Amur Honeysuckle on Spring Wildflowers
While Honeysuckle has already been shown to have detrimental effects on local species, such as in Miller and Gorchov’s study (2004), this on-going research* seeks to look at what impact honeysuckle has on the emergence and blooming of spring flowers. To do this, three sites in Miami University’s Western Woods were set up, each site […]
C38: Compact Imaging of a Laser Beam using a Polarimeter

C39:Developing a Non-Contact DCS System for Biological Tissue Scans
DCS measures light intensity fluctuations of blood flow in deep tissue as time passes between detection of each photon. Using fiber optic probes, a DCS system directs light from a laser into a tissue sample, and then into a single photon detector. When the laser hits the sample through the multi modal probe, light is […]
C40: Enhancing Gene Expression Quantification through Non-Reference Structural Variant Identification
The release of the human reference genome (GRCh38) in 2003 was a significant milestone in genetics, offering potential advancements in understanding and treating genetic diseases and traits. Despite having been gradually improved for two decades, GRCh38 still possesses limitations in measuring gene expressions mainly due to a lack of diversity derived from structural variants (SVs). […]
