Vergence Task-Based Neural Pathways With Binocularly Normal Vision And Comorbid Persistent Post-Concussive Symptoms -Convergence Insufficiency, Ayushi Sangoi May 2026

Vergence Task-Based Neural Pathways With Binocularly Normal Vision And Comorbid Persistent Post-Concussive Symptoms -Convergence Insufficiency, Ayushi Sangoi

Dissertations

Binocular dysfunctions are more prevalent in the persistent post-concussive symptoms (PPCS) population than in the general population. The most prevalent binocular disorder is convergence insufficiency (CI), affecting 3-17% of the general population and up to 10 times as many people with PPCS. CI makes it difficult to fuse or maintain fusion on targets at near, and its symptoms include double or blurry vision and headaches when performing close-range tasks such as reading, which can exacerbate PPCS symptoms. Given controversy over the subjectivity and effectiveness of diagnostic tools and symptom surveys for both PPCS and CI, understanding why CI has high …


Transcranial Ac Modulation Of Cerebellar Nuclear Activity In Awake Animals, Nuran Kavakli May 2026

Transcranial Ac Modulation Of Cerebellar Nuclear Activity In Awake Animals, Nuran Kavakli

Dissertations

Entrainment of cerebellar nuclear (CN) cells via cerebellar transcranial alternating current stimulation (ctACS) has been reported in animals under ketamine/xylazine anesthesia. Our main objective was to demonstrate modulation of CN activity in unanesthetized, freely moving animals using ctACS. Multi-channel carbon-fiber electrodes were implanted into the interpositus nucleus for recording multi-unit (MU) activity, and thin-film electrodes were implanted subcutaneously over the posterior cerebellum for stimulation. A frequency-domain-based metric was developed to quantify modulation from MU signals. The results demonstrated modulation in a wide range of frequencies (4 Hz-300 Hz) as in anesthetized animals. In contrast, the amplitude of the peak in …


The Cultivation Of Public Perception: Cultivated Meat Narratives And Misinformation On Tiktok, Anna M. Balkus May 2026

The Cultivation Of Public Perception: Cultivated Meat Narratives And Misinformation On Tiktok, Anna M. Balkus

Graduate Masters Theses

Cultivated meat is an emerging tissue engineering technology that has the potential to address major issues threatening food systems, including climate change, rapid population growth, and the spread of disease. Among technical challenges, public perception remains a significant barrier for the widespread adoption of cultivated meat. While social media has transformed communication globally, it has simultaneously contributed to corrupt online environments infected with misinformation—unintentional inaccuracies that differ from disinformation, which is spread with the intent to mislead. The way the public receives and digests information regarding new food technologies, like cultivated meat, will be shaped by their social media environment. …

The Effect Of Incompatibility Types On The Escalation Of Global Armed Conflicts, Michael Haratua Rajagukguk, Ruben Cornelius Siagian Rcs May 2026

The Effect Of Incompatibility Types On The Escalation Of Global Armed Conflicts, Michael Haratua Rajagukguk, Ruben Cornelius Siagian Rcs

Journal of Terrorism Studies

Global armed conflicts show variations in intensity influenced by the type of issue incompatibility. This study aims to analyze the influence of territorial, ideological, and combined incompatibilities on the probability of high-intensity conflict escalation, as well as its implications for conflict mitigation strategies. Global conflict dyadic data were analyzed using a multilevel logistic regression model with controls for time, region, and conflict type. The results show that ideology-based conflicts have a lower probability of reaching high intensity than territorial conflicts (OR ≈ 0.51, p < 0.05), while conflicts with a combination of ideology and territory tend to be at greater risk of high escalation (AM effect ≈ +26.6 points), although the effect is not yet statistically significant. Temporal analysis shows a downward trend in conflict intensity over time, especially in the post-Cold War period, while regional effects and conflict types show significant variation. These findings fill a gap in the literature on the dual interaction of ideological and territorial claims, showing that the highest escalation of violence occurs when symbolic and material dimensions are intertwined. In conclusion, conflict escalation is more influenced by a combination of issues and structural characteristics of conflict than by ideology alone. The novelty of this research lies in the identification of the strengthening effect of dual incompatibility and the downward trend in conflict intensity after the Cold War, which emphasizes the importance of a relational and temporal context-based mitigation approach in global conflict management.

Kesmas

Stunting remains the largest public health challenge among macro-nutrition problems in Indonesia, affecting almost a quarter of children under five in 2023. The prevalence is considered high according to the World Health Organization standard. This study analyzed 15 aggregated provincial variables from the 2023 Indonesian Health Survey using Structural Equation Modeling (SEM), focusing on determinants of stunting among children under two to identify primary intervention levers. Findings indicated that intervention urgency should focus on the first 1,000 days, particularly the steep increase in stunting prevalence observed in the 12–24-month age range. While the highest prevalence is in Eastern provinces (e.g., …


Impact Of Package Dimension Changes On The Consumer’S Perception Of Ready-To-Eat Meal Serving Size, Greg Roskos, Koushik Saha May 2026

Impact Of Package Dimension Changes On The Consumer’S Perception Of Ready-To-Eat Meal Serving Size, Greg Roskos, Koushik Saha

Journal of Applied Packaging Research

Consumers increasingly scrutinize changes in food packaging, particularly in the context of “shrinkflation,” yet little empirical work has examined whether small dimensional changes in primary packaging affect perceived value when product weight is held constant. This study investigates the impact of minor tray dimension changes on consumers’ perception of serving size and product quality for ready-to-eat (RTE) frozen meals. Three single-compartment tray formats were evaluated: a control tray, a larger-volume tray (~18% increase), and a hybrid tray with an intermediate volume (~8% increase). All trays contained identical net product weight. Thirty-six untrained panelists from a local community participated in a …


Patents And Technology Evolution: Altering Innovations And Innovators Via Patent Influences, Richard Gruner May 2026

Patents And Technology Evolution: Altering Innovations And Innovators Via Patent Influences, Richard Gruner

Journal of Intellectual Property Law

Technologies improve primarily through evolutionary change not rational optimization. New technologies emerge as attempts to solve practical problems, the technologies are tested in marketplaces to determine if they are superior in cost and function to alternatives, and those that fare well in the testing gain widespread adoption.  Widely adopted technologies, and their problems, form the basis for the next round of technology improvements and evolution.  Through these steps, evolutionary processes lacking rational direction can generate changing technologies matched to the desires and problems of present society.

As they operate to advance diverse technologies, evolutionary processes governing technology change are subject …

Collections Of Western Wheatgrass And Blue Grama And Associated Nematode Genera In The Western Dakotas, R E. Barker, J D. Berdahl, J M. Krupinsky, E T. Jacobson

IGC Proceedings (1977-2023)

Western wheatgrass (Agropyron smithii Rydb.) and blue grama (Bouteloua gracilis[Willd. ex H.B.K.J Lag. ex Griffiths) are widely distributed throughout the U.S.A. They arc two of the predominant native grasses in rangelands in the northern Great Plains. Because suitable cultivars are not always available for reseeding disturbed areas, we collected plants of the two species and evaluated phenotypic variability to determine potential for breeding improvement. We also sampled the nematode popula­tion associated with the collections. Sampling sites were systematically chosen by establishing a grid pattern 19 .3 km apart in the western halves of North Dakota and South Dakota. …

Visualizing Ozone Pollution In The Denver Metro Area Using A Bioindicator Garden, Ella K. Mathews, Hillary Hamann, Julie Morris, Erica L. Larson

DU Undergraduate Research Journal Archive

Since the industrial revolution, widespread fossil fuel combustion has significantly increased atmospheric pollution. The combustion of fossil fuels releases nitrogen oxides (NOx) and volatile organic compounds (VOCs), which form tropospheric (ground-level) ozone when exposed to sunlight. Ozone directly harms plants by disrupting their ability to absorb carbon dioxide, release oxygen, and carry out photosynthesis. Bioindicator species are plants that have visible responses to environmental conditions, such as ozone, and can act as “canaries in the coal mine,” indicating the health of their environment. In this study, we used a garden of ozone bioindicator species (ozone garden) as a cost-effective tool …

Department of Biochemistry and Molecular Biology Faculty Papers

Ergosteryl-3β-O-L-aspartate synthase (ErdS) catalyzes tRNA-dependent aspartylation of ergosterol, a lipid essential for fungal cell membrane integrity. However, the functional significance of ergosteryl-aspartate and the molecular mechanisms underlying its synthesis remain unclear. Here, we show that ErdS localization is highly dynamic and that Erg-Asp is required for proper hyphal growth, sporulation, and spore germination, and likely influences stress tolerance. The cryo-electron microscopy structure of ErdS revealed an unprecedented sterol-binding pocket. In addition, the structures in complex with a non-hydrolyzable Asp-N-tRNAAsp show a tRNA-guided intramolecular aminoacyl transfer mechanism between two functional domains of the enzyme. The CCA end of tRNAAsp undergoes a …

Department of Agricultural Economics Faculty Publications

Many topics in the behavioral sciences and epidemiology require researchers to directly observe entities (e.g., individuals, households) over a long time to identify lasting effects. Long-term panel data collection is more common in high-income countries than in small-scale rural societies (SSRS) of low-income countries. SSRS are mobile, nature-dependent, linguistic minorities, and highly autarkic. Analyzing such data using a life-course perspective can help uncover patterns that align or upend what we know from high-income countries. This study a) reviews long (>∼10 year) panels in SSRS (n = 9), b) extends the analysis to cover somewhat comparable societies of smallholders (n …

Background: Triple-negative breast cancer (TNBC) is an aggressive subtype with limited treatment options and poor prognosis. Understanding the underlying molecular mechanisms, particularly immune-related gene networks, is critical for identifying novel therapeutic targets. Aim: This study aimed to identify immune-related hub genes involved in TNBC progression by integrating microarray and RNA sequencing data. Methods: We integrated microarray and RNA sequencing datasets from five Gene Expression Omnibus (GEO) studies (GSE36295, GSE37751, GSE61724, GSE38959, and GSE58135) to identify differentially expressed genes (DEGs). Protein–protein interaction (PPI) networks were constructed using the STRING database. Key modules and hub genes were identified through network analysis. …

BioMedicine

Background: Bai-Zhu (Atractylodes macrocephala Koidz. [Asteraceae]) is classified in traditional Chinese medicine (TCM) as an herb that targets the gastric and pancreatic meridians to support normal nutrient uptake. As such, Bai-Zhu is commonly included in herbal formulations for treating gastrointestinal dysfunction and alleviating pain and swelling. Formulae containing Bai-Zhu are also frequently used as complementary or alternative therapies to mitigate the side effects of tumor treatments. However, their direct effects on cancer cells remain inadequately understood in modern biomedical science. This study aims to characterize the impact of Bai-Zhu-containing formulae on breast cancer cells using contemporary molecular and cellular …

BioMedicine

Background: Emodin exhibits various pharmacological activities, including hepatoprotective effects. However, its clinical application is limited by poor absorption and low oral bioavailability. This study aimed to optimize emodin through benzoylation and to assess the hepatoprotective potential of the resulting derivatives integrating bioinformatics and in vitro methods.

Methods: We conducted network pharmacology, molecular docking and molecular dynamics (MD) simulations to predict potential targets and interactions of benzoylated emodin derivatives. The derivatives were synthesized and evaluated for cytotoxicity using the MTT assay. The hepatoprotective effects were assessed in vitro using a paracetamol-induced HepG2 cell injury model.

Results: Network pharmacology analysis and gene …
