Optimal Manipulation Motion Action Planner Enabled By Physics Informed Neural Networks, Jonathon E. Slightam, Logan E. Beaver Jan 2025

Optimal Manipulation Motion Action Planner Enabled By Physics Informed Neural Networks, Jonathon E. Slightam, Logan E. Beaver

Mechanical & Aerospace Engineering Faculty Publications

Autonomous robotic manipulation in unstructured environments faces many challenges and is hindered by capabilities that bridge the gap between perception and acting on the world. Action plans that are centric to object motion rather than end-of-arm tooling behavior may aid this. This paper presents an autonomous action planner for a feedback linearizeable system comprised of three base motions that can be leveraged on their own or in combination to give custom motion plans. The optimization routine for the three different types of motion are presented, which are integrated into physics informed neural networks. A component of this is the autonomy …

Collision-Induced Absorption Spectra Of N₂ And Ch₄, Ryan M. Johnson, Peter F. Bernath, Brant Billinghurst, Jianbao Zhao Jan 2025

Collision-Induced Absorption Spectra Of N₂ And Ch₄, Ryan M. Johnson, Peter F. Bernath, Brant Billinghurst, Jianbao Zhao

Chemistry & Biochemistry Faculty Publications

Collision-induced spectra are essential for radiative transfer modeling of Titan's atmosphere. We present experimental spectra of nitrogen–methane mixtures with an accompanying fit of N₂-CH₄ collision-induced absorption in the 30–400 cm⁻¹ region at about 130 K. We found a peak absorption of 2.30 × 10⁻⁵ cm⁻¹ amagat⁻² at 75 cm⁻¹ and a secondary peak of 1.35 × 10⁻⁵ c⁻¹ amagat⁻² at 206.5 cm⁻¹, which agrees with previous studies. Our work does not support the suggestion that N₂-CH₄ CIA in the far-infrared should be increased by about 50%, as suggested by spectroscopic modeling of Titan using data from A. Borysow & C. …

Transient Transmembrane-Electrostatically Localized Protons And Transmembrane Potential In A Laser Flashed Bacteriorhodopsin Purple Membrane Open Flat Sheet - Summary, James Weifu Lee

Chemistry & Biochemistry Faculty Publications

The transmembrane-electrostatically localized protons/cations charges (TELCs, also known as TELPs) model may serve as a unified framework to explain a wide range of bioenergetic phenomena. Transient transmembrane-electrostatically localized protons (TELPs) and transmembrane potential in a laser flash-energized bacteriorhodopsin (bR) purple membrane (PM) open flat sheet are now better analyzed. Under the Heberle et al. (1994) experimental conditions, the number of bR molecules is now calculated to be 8200 per PM open flat sheet with a diameter of 600 nm. With a single-turnover laser flash intensity of 3 mJ/cm² to photoexcite 10% of the bR molecules, the laser flash-induced peak TELCs …

Mindfulness And Psychological Adjustment In International Students: The Mediating Role Of Emotion Regulation Strategies, Jyoti Lama Jan 2025

Mindfulness And Psychological Adjustment In International Students: The Mediating Role Of Emotion Regulation Strategies, Jyoti Lama

Masters Theses

This study examined the relationship between mindfulness and psychological adjustment among international students, focusing on the mediating roles of two emotion regulation strategies: cognitive reappraisal and expressive suppression. Specifically, it explored whether mindfulness is associated with lower acculturative stress and higher coping self-efficacy, and whether using the emotion regulation strategies of cognitive appraisal and expressive suppression mediate these relationships. Eighty-nine international students from mid-sized U.S. universities participated in an online survey assessing mindfulness, emotion regulation, acculturative stress, and coping self-efficacy. Mediation analyses using bootstrapping showed that cognitive reappraisal partially mediated the relationship between mindfulness and coping self-efficacy, but not between …

Finding Love On The Spectrum: An Analysis Of Social And Romantic Relationships Of Autistic College Students, Kaylee Spinner Jan 2025

Finding Love On The Spectrum: An Analysis Of Social And Romantic Relationships Of Autistic College Students, Kaylee Spinner

Masters Theses

Autism Spectrum Disorder (ASD) is characterized by difficulties in socialization, communication, and developing relationships with others. While many autistic individuals desire to start relationships with others, many do not have a very strong understanding of the use of nonverbal communication or how to develop these connections organically. As autistic individuals have become more open about wanting these resources to form social and romantic relationships, there has been more of a push in the literature to include social skills training for forming social relationships. However, the research on the desire for or development of romantic relationships for autistic individuals is still …

Mindfulness & Mental Health: Balanced Time Perspective As A Mediator, Eddie Trueblood Jan 2025

Mindfulness & Mental Health: Balanced Time Perspective As A Mediator, Eddie Trueblood

Masters Theses

Mindfulness is a practice of intentionally paying attention to the present moment in a nonjudgmental way. Being more mindful can decrease symptoms of anxiety, depression, and stress, among other mental and physical health improvements. (Donald et al., 2016; Hofmann et al., 2010; Kabat-Zinn et al.,1992). This study examined if balanced time perspective (BTP) is one of the mechanisms of action of mindfulness in its relationship with depression, anxiety, and stress. BTP refers to a person’s ability to flexibly adapt their time perspective (attention to the past, present, or future, and positive or negative attitudes toward each) to suit the current …

Are There Predictable Shifts In Fish Communities Following Instream Habitat Restoration? A Multistream Analysis., Ryan A. Skowronski Jan 2025

Are There Predictable Shifts In Fish Communities Following Instream Habitat Restoration? A Multistream Analysis., Ryan A. Skowronski

Masters Theses

In the past two centuries, anthropogenic stressors have degraded the structure and function of streams by accelerating bank erosion, decreasing riparian buffer zones, and altering the natural flow regime. Habitat restoration has become a common mitigation strategy in response to stream degradation, though empirical research evaluating its effectiveness is lacking in the United States. This study investigated responses in fish community following habitat restoration in five restored, Illinois streams. We assigned fish species to habitat, trophic, and reproductive guilds based on their habitat preferences, feeding habits, and life history. Streams were separated into enhancement and removal groups for analysis. Shifts …

Assessing The Role Of Daily Thermal Fluctuations In The Performance Of Mitochondrial Energy Transduction Of The Centrarchid, Lepomis Cyanellus, Grayson Hofmann Jan 2025

Assessing The Role Of Daily Thermal Fluctuations In The Performance Of Mitochondrial Energy Transduction Of The Centrarchid, Lepomis Cyanellus, Grayson Hofmann

Masters Theses

Freshwater systems are affected by current climate extremes, forcing species found in these systems to withstand drastic changes in temperature. Temperature changes affect these organisms by altering their metabolic rate and energy balance. Increases in temperature can lead to an increase in oxygen consumption, which ultimately increases the need for more energy production. Mitochondrial energy transduction of green sunfish (Lepomis cyanellus) and many other fish species after a thermal insult, has hardly been explored. This study complements the limited research available on mitochondrial function in similar species, as they ignore the possibility of consecutive thermal events, which are …

Simpson's Tachytely Or Bradytely? The Importance Of Quantifying Rate Uncertainty, Rosana Zenil-Ferguson, Lee Hsiang Liow Jan 2025

Simpson's Tachytely Or Bradytely? The Importance Of Quantifying Rate Uncertainty, Rosana Zenil-Ferguson, Lee Hsiang Liow

Biology Faculty Publications

The spectacular variation in species forms and richness across space and time can be explored using sophisticated and powerful tools recently developed by evolutionary modellers. In this contribution, we ask if the classic ‘Simpsonian’ view of tachytelic (fast), horotelic (standard) and bradytelic (slow) diversification rates can be distinguished with currently available tools and data. A neglected topic here is the role that the uncertainty of diversification rate estimates plays, where the lack of in-depth uncertainty measures could hinder our ability to confidently suggest differences in speciation or extinction rates in any given comparison. We propose quantifying the relative uncertainty of …

Seasonal Divergence In Reproductive Timing On The Verge Of Spring, Devraj Singh, Adam M. Fudickar, Ellen D. Ketterson Jan 2025

Seasonal Divergence In Reproductive Timing On The Verge Of Spring, Devraj Singh, Adam M. Fudickar, Ellen D. Ketterson

Biology Faculty Publications

Every year as spring approaches and day length increases, many birds begin to reproduce, an annual expression of seasonal phenology that requires physiological preparation. In species distributed over a broad geographic range, populations that breed at higher latitudes are often migratory and delay reproduction until later in the year as compared to those breeding at lower latitudes. Dark-eyed Juncos serve as an excellent model for understanding the timing mechanisms regulating population-level variation in seasonal reproductive responses. We compared two seasonally sympatric dark-eyed junco populations in early spring. One migrates (Junco hyemalis hyemalis) and breeds in Alaska and Canada, while the …

Chromatin Remodeling Protein Bptf Mediates Chromatin Accessibility At Gene Promoters In Planarian Stem Cells, Prince Verma, John M. Allen, Alejandro Sánchez Alvarado, Elizabeth M. Duncan

Biology Faculty Publications

Background The regulation of chromatin accessibility is essential in eukaryotic cells as one of several mechanisms that ensure gene activation occurs at appropriate times and in appropriate cell types. Accordingly, mutations in chromatin remodeling proteins are linked to many different developmental disorders and cancers. One example of a chromatin protein that has been linked to both developmental abnormalities and cancer is BPTF/NURF301, the largest subunit of the Nucleosome Remodeling Factor (NuRF) complex. The BPTF subunit is not only important for the formation of NuRF but also helps direct its activity to particular regions of chromatin by preferentially binding histone H3 …
