    Manganese Carbonate/Laser-Induced Graphene Composite for Glucose Sensing
    (2023) Thakur, Amit K. (TTU); Sengodu, Prakash; Jadhav, Arvind H.; Malmali, Mahdi (TTU)
    Laser-induced graphene (LIG) has received great interest as a potential candidate for electronic and sensing applications. In the present study, we report the enhanced performance of a manganese carbonate-decorated LIG (MnCO3/LIG) composite electrode material employed for electrochemical glucose detection. Initially, the porous LIG was fabricated by directly lasing poly(ether sulfone) membrane substrate. Then, the MnCO3/LIG composite was synthesized via a hydrothermal method. Later, MnCO3/LIG was immobilized onto a glassy carbon electrode surface and employed for glucose detection. The structure of the MnCO3/LIG composite was carefully characterized. The influence of the MnCO3/LIG composite on the performance of the electrode was investigated using cyclic voltammetry curves. The MnCO3/LIG composite exhibited an excellent sensitivity of 2731.2 μA mM-1 cm-2, and a limit of detection of 2.2 μM was obtained for the detection of glucose. Overall, the performance of the MnCO3/LIG composite was found to be superior to that of most of the MnCO3-based composites.

    Development of a Polymicrobial Checkerboard Assay as a Tool for Determining Combinatorial Antibiotic Effectiveness in Polymicrobial Communities
    (2023) Black, Caroline (TTU); Al Mahmud, Hafij (TTU); Howle, Victoria (TTU); Wilson, Sabrina (TTU); Smith, Allie C. (TTU); Wakeman, Catherine A. (TTU)
    The checkerboard assay is a well-established tool used to determine the antimicrobial effects of two compounds in combination. Usually, data collected from the checkerboard assay use visible turbidity and optical density as a readout. While helpful in traditional checkerboard assays, these measurements become less useful in a polymicrobial context as they do not enable assessment of the drug effects on the individual members of the community. The methodology described herein allows for the determination of cell viability through selective and differential plating of each individual species in a community while retaining much of the high-throughput nature of a turbidity-based analysis and requiring no specialized equipment. This methodology further improves turbidity-based measurements by providing a distinction between bacteriostatic versus bactericidal concentrations of antibiotics. Herein, we use this method to demonstrate that the clinically used antibiotic combination of ceftazidime and gentamicin works synergistically against Pseudomonas aeruginosa in monoculture but antagonistically in a polymicrobial culture also containing Acinetobacter baumannii, Staphylococcus aureus, and Enterococcus faecalis, highlighting the fundamental importance of this methodology in improving clinical practices. We propose that this method could be implemented in clinical microbiology laboratories with minimal impact on the overall time for diagnosis.

    MODELING AND ANALYSIS OF SOCIAL OBESITY EPIDEMIC
    (2024) Sandamali, Chathuri T.; Zhang, Wenjing (TTU)
    Overweight and obesity have become a global epidemic due to increasing unhealthy eating habits and sedentary lifestyles. An individual can gain weight excessively through social influence, and understanding its underlying interpersonal dynamics is crucial for effective intervention and prevention programs. By considering the social effects on weight gain, this paper presents a compartment model to describe the social spread of overweight and obesity. Bifurcation analysis suggests that a backward bifurcation exists when the relative hazard of weight regain is a larger value. Strategies for eliminating the overweight and obesity epidemic are provided by analyzing the obesity-free equilibrium globally by incorporating Lyapunov functions and the method of fluctuations. Since the pervasiveness of overweight and obesity in the United States seems to be stabilized, we analyze the local stability of the obesity-endemic equilibrium to establish a condition for the plateau, by applying a matrix theoretic method that utilizes compound matrices. The results suggest that weight loss programs can help maintain the plateau; however, weight loss maintenance programs should be promoted to eliminate the disease.

    Louvain-Based Traffic Object Detection for Roadside 4D Millimeter-Wave Radar
    (2024) Gong, Bowen; Sun, Jinghang; Lin, Ciyun; Liu, Hongchao; Sun, Ganghao
    Object detection is the fundamental task of vision-based sensors in environmental perception and sensing. To leverage the full potential of roadside 4D MMW radars, an innovative traffic detection method is proposed based on their distinctive data characteristics. First, velocity-based filtering and region of interest (ROI) extraction were employed to filter and associate point data by merging the point cloud frames to enhance the point relationship. Then, the Louvain algorithm was used to divide the graph into modularity by converting the point cloud data into graph structure and amplifying the differences with the Gaussian kernel function. Finally, a detection augmentation method is introduced to address the problems of over-clustering and under-clustering based on the object ID characteristics of 4D MMW radar data. The experimental results showed that the proposed method obtained the highest average precision and F1 score: 98.15% and 98.58%, respectively. In addition, the proposed method showcased the lowest over-clustering and under-clustering errors in various traffic scenarios compared with the other detection methods.

    Inter-stage performance and energy characteristics analysis of electric submersible pump based on entropy production theory
    (2024) Wang, Hui; Yang, Yang; Xi, Bin; Shi, Wei Dong; Wang, Chuan; Ji, Lei Lei; Song, Xiang Yu; He, Zhao Ming (TTU)
    The electric submersible pump (ESP) is a crucial apparatus utilized for lifting in the oil extraction process. Its lifting capacity is enhanced by the multi-stage tandem structure, but variations in energy characteristics and internal flow across stages are also introduced. In this study, the inter-stage variability of energy characteristics in ESP hydraulic systems is investigated through entropy production (EP) analysis, which incorporates numerical simulations and experimental validation. The EP theory facilitates the quantification of energy loss in each computational subdomain at all ESP stages, establishing a correlation between microscopic flow structure and energy dissipation within the system. Furthermore, the underlying causes of inter-stage variability in ESP hydraulic systems are examined, and the advantages and disadvantages of applying the EP theory in this context are evaluated. Consistent energy characteristics within the ESP, aligned with the distribution of internal flow structure, are provided by the EP theory, as demonstrated by our results. The EP theory also enables the quantitative analysis of internal flow losses and complements existing performance analysis methods to map the internal flow structure to hydraulic losses. Nonetheless, an inconsistency between the energy characterization based on EP theory and the traditional efficiency index when reflecting inter-stage differences is identified. This inconsistency arises from the exclusive focus of the EP theory on flow losses within the flow field, disregarding the quantification of external energy input to the flow field. This study provides a reference for the optimization of EP theory in rotating machinery while deeply investigating the energy dissipation characteristics of multistage hydraulic system, which has certain theoretical and practical significance.

    Validation of an enzyme immunoassay for the detection of corticosterone metabolites from northern bobwhite (Colinus virginianus) feces
    (2024) Leach, Jeremiah (TTU); Suber, Hannah N. (TTU); Conley, Katelyn (TTU); Rivera, Regan (TTU); Surles, James (TTU); Hames, Benjamin (TTU); Kendall, Ronald J. (TTU)
    Interest in the effects of stressors on wildlife has grown substantially over the past few decades. As this interest has grown, so has the need for minimally invasive and reliable methods for estimating differences in the levels of stress hormones. An enzyme immunoassay using standardized methods was validated for detecting concentrations of corticosterone (cort) metabolites from northern bobwhite fecal samples. Two physiological challenges and one biological challenge were applied to 18 northern bobwhites (nine males and nine females), and the fecal cort metabolite concentrations were compared to baseline levels. The interactions of sex and treatment, treatment and time and sex and time were all significant. Thus, the methods and tools used here were sensitive enough to detect expected changes to the hypothalamo–pituitary–adrenal axis of northern bobwhite.

    Acceptability of a Self-Led Mindfulness-Based Intervention for Teens with Type 1 Diabetes: Pilot Randomized Controlled Trial
    (2024) Humiston, Tori; Cummings, Caroline (TTU); Suss, Stephen; Cohen, Laura B.; Hazlett-Stevens, Holly; Lansing, Amy Hughes
    Background: Diabetes distress among adolescents with type 1 diabetes has been associated with suboptimal diabetes outcomes, including lower quality of life, increased diabetes self-management challenges, and suboptimal glycemic outcomes. Objective: This study examined the feasibility and acceptability of a scalable self-led mindfulness-based intervention to reduce diabetes distress in adolescents with type 1 diabetes. Methods: Adolescents (N=25) aged between 14 and 18 years diagnosed with type 1 diabetes completed a baseline assessment. Participants were randomized to receive a 10-week self-guided mindfulness-based stress reduction workbook program (e-book or paper option) immediately (n=15) or after a 10-week wait (n=10). During the intervention period, participants completed weekly assignments and feedback surveys. At 10 weeks and 20 weeks, follow-up assessments were completed. Results: Findings indicated that participants did not find the original intervention feasible or acceptable. Adolescents reported barriers to completing the weekly material, such as that they forgot or that the material was not sufficiently related to their diabetes management. Adolescents also reported that a digital format rather than a workbook or e-book may be more acceptable. Results from weekly surveys provided the foundation for recommendations for future iterations of the mindfulness-based intervention for adolescents with type 1 diabetes. Conclusions: Participant feedback informed recommendations for self-led mindfulness programs for youth with type 1 diabetes. Adolescents indicated that a shorter, digital mindfulness-based intervention focused on diabetes-specific behaviors may be more helpful.

    Fatty acid unsaturation improves germination of upland cotton (Gossypium hirsutum) under cold stress
    (2024) Dhaliwal, Lakhvir Kaur (TTU); Shim, Junghyun (TTU); Auld, Dick (TTU); Angeles-Shim, Rosalyn B. (TTU)
    Introduction: The level of fatty acid unsaturation in seeds is one of the major determinants of cold germination ability, particularly in oilseeds. The presence of cis double bonds in unsaturated fatty acids creates bends that lowers their melting temperatures compared to saturated fatty acids. Unsaturated fatty acids with low melting points mobilize faster at low temperatures providing seeds with sufficient energy for germination. Methodology: To investigate the effects of fatty acid unsaturation on the ability of cotton seeds to germinate under cold conditions, four recombinant inbred lines (RILs) of cotton with unique fatty acid profiles were evaluated using a set of developmental and biochemical assays at 12°C (critically low temperature), 15°C (cardinal minimum temperature) and 30°C (optimum temperature). Furthermore, whole seed lipidome profiling using liquid chromatography with mass spectrometry was done to compare the lipid compositional changes at 12°C and 30°C after imbibing cotton seeds of all the six genotypes for 0 hours, 3 hours and 6 hours. Results and discussion: The RILs with higher unsaturation/saturation ratios registered robust germination performance, lower solute leakage, and optimum water uptake rates under cold stress. Imbibition at 30°C for 8 hours before cold exposure significantly improved the germination of cold sensitive genotypes, indicating that the first few hours of water uptake are critical for cold stress. Whole seed lipidome profiling of all the genotypes specifically associated cold germination ability with higher unsaturation levels of phospholipids during early imbibition. The presence of cis double bonds in phospholipids creates kinks that maintain the fluidity of cell membranes under low temperature. Membrane flexibility under cold conditions is essential for facilitating key germination events including membrane organization and respiration. The current results highlight the importance of fatty acid composition in cold germination ability of upland cotton.

    Efficacy of remote sensing technologies for burrow count estimates of a rare kangaroo rat
    (2024) Stuhler, John D.; Portillo-Quintero, Carlos (TTU); Goetze, Jim R. (TTU); Stevens, Richard D. (TTU)
    Effective management of rare species requires an understanding of spatial variation in abundance, which is challenging to estimate. We tested the efficacy of high-resolution imagery to detect burrows of the Texas kangaroo rat (TKR; Dipodomys elator) as a means of estimating abundance across its geographic range. Specifically, we estimated burrow counts using an Unmanned Aerial System (UAS) to collect data from very high-resolution Red–Green–Blue (RGB) imagery and estimate digital elevation (2.5-mm pixel resolution) over active and inactive burrows located on mesquite mounds and anthropogenic features (roadsides, fences, etc.). In 2018, we identified 26 burrow locations on a private ranch in Wichita County, Texas, USA, and characterized burrows based on topography and vegetation density. We found that TKR burrows can only be identified with data of <5 cm pixel resolution, thus eliminating the possibility of using high-resolution imagery data currently available for Texas. Alternatively, we propose that the use of National Agriculture Imagery Program (NAIP) imagery at 0.5- and 0.6-m pixel resolution, in combination with resampled digital elevation data, can provide an effective means for identifying potential TKR burrow locations at the county level. We present 3 different approaches at the county and local scale that combine topographic and vegetation fractional cover information using a weighted overlay approach. The modeling approaches have strong predictive capabilities and can be integrated with UAS data for visual confirmation of active and inactive burrows. We concluded that very high-resolution imagery and topographic information at pixel resolutions <5 cm collected by airborne systems can effectively help locate active TKR burrows. However, to remain cost effective, upscaling to the county level will require reducing the sampling area to the most suitable habitat. Modeling approaches, such as those proposed in this study, can help effectively locate these sampling areas.

    The ants of the Galápagos Islands (Hymenoptera, Formicidae): a historical overview, checklist, and identification key
    (2024) Herrera, Henri W.; Tocora, María C. (TTU); Fiorentino, Gianpiero; Causton, Charlotte E.; Dekoninck, Wouter; Hendrickx, Frederik
    The Galápagos ant fauna has long been understudied, with the last taxonomic summary being published almost a century ago. Here, a comprehensive and updated overview of the known ant species of the Galápagos Islands is provided with updated species distri-butions. The list is based on an extensive review of literature, the identification of more than 382,000 specimens deposited in different entomological collections, and recent expeditions to the islands. The ant fauna is composed of five subfamilies (Dolichoderi-nae, Dorylinae, Formicinae, Myrmicinae, and Ponerinae), 22 genera, 50 species, and 25 subspecies, although three species (Crematogaster crinosa Mayr, 1862, Camponotus senex (Smith, 1858), and Solenopsis saevissima (Smith, 1855)) are considered dubious records. Finally, an illustrated identification key of the species found in the archipelago is presented.

    Flocculation characteristics of suspended Mississippi River mud under variable turbulence, water and salt sources, and salinity: a laboratory study
    (2024) Abolfazli, Ehsan; Osborn, Ryan; Dunne, Kieran B.J.; Nittrouer, Jeffrey A. (TTU); Strom, Kyle
    Muddy sediment constitutes a major fraction of the suspended sediment mass carried by the Mississippi River. Thus, adequate knowledge of the transport dynamics of suspended mud in this region is critical in devising efficient management plans for coastal Louisiana. We conducted laboratory tank experiments on the sediment suspended in the lower reaches of the Mississippi River to provide insight into the flocculation behavior of the mud. In particular, we measure how the floc size distribution responds to changing environmental factors of turbulent energy, sediment concentration, and changes in base water composition and salinity during summer and winter. We also compare observations from the tank experiments to in situ observations. Turbulence shear rate, a measure of river hydrodynamic energy, was found to be the most influential factor in determining mud floc size. All flocs produced at a given shear rate could be kept in suspension down to shear rates of approximately 20 s−1. At this shear rate, flocs on the order of 150–200 μm and larger can settle out. Equilibrium floc size was not found to depend on sediment concentration; flocs larger than 100 μm formed in sediment concentrations as low as 20 mgL−1. An increase in salinity generated by adding salts to river water suspensions did not increase the flocculation rate or equilibrium size. However, the addition of water collected from the Gulf of Mexico to river-water suspensions did enhance the flocculation rate and the equilibrium sizes. We speculate that the effects of Gulf of Mexico water originate from its biomatter content rather than its ion composition. Floc sizes in the mixing tanks were comparable to those from the field for similar estimated turbulent energy. Flocs were found to break within minutes under increased turbulence but can take hours to grow under conditions of reduced shear in freshwater settings. Growth was faster with the addition of Gulf of Mexico water. Overall, the experiments provide information on how suspended mud in the lower reaches of the Mississippi might respond to changes in turbulence and salinity moving from the fluvial to marine setting through natural distributary channels or man-made diversions.

    State of knowledge of the Anthribidae (Insecta: Coleoptera: Curculionoidea) in Colombia with a key to genera Estado del conocimiento de los Anthribidae (Insecta: Coleoptera: Curculionoidea) de Colombia con clave a los géneros
    (2024) Orellana, K. Samanta; Girón, Jennifer C. (TTU)
    Anthribidae is a small family of beetles known as fungus weevils, for which the state of knowledge for Colombian species has never been synthesized. Anthribids are scarce in Colombian biological collections and are usually only identified at the family level. We updated the list of species of fungus weevils recorded from Colombia. There are 37 species of anthribids recorded for the country, placed into 14 genera, 10 tribes, and 2 subfamilies. Three additional genera have been observed in the country based on records from the online platform iNaturalist. Verification of these records and species-level identifications require the revision of national biological collections. We discuss the biodiversity of Colombian fungus weevils compared to neighboring countries and provide a key to identify the genera present in Colombia. The species Domoptolis championi Jordan, 1906 is recorded for Colombia for the first time.

    Development of a mini pig model of peanut allergy
    (2024) Shakya, Akhilesh Kumar (TTU); Backus, Brittany (TTU); Nesovic, Lazar D. (TTU); Mallick, Malini (TTU); Banister, Olivia (TTU); Davis, Carla M.; Anvari, Sara; Gill, Harvinder Singh (TTU)
    Introduction: The prevalence of peanut allergies is increasing, emphasizing the need for an animal model to enhance our understanding of peanut allergy pathogenesis and to advance diagnostic tools and therapeutic interventions. While mice are frequently used as model organisms, their allergic responses do not fully mirror those observed in humans, warranting the exploration of a higher animal model. The porcine gastrointestinal system closely resembles that of humans, and exhibits allergy symptoms akin to human responses, making pigs a promising model for peanut allergy research. Methods: In this study we compared two allergen sensitization protocols involving either topical allergen application after repeated tape stripping (TS) or intraperitoneal (IP) injections to induce peanut-specific allergy and anaphylaxis reactions in mini pigs. Mini pigs sensitized with a combination of peanut protein extract (PE) and cholera toxin (CT) through either the IP or the TS route. Results: Sensitized pigs via both methods developed systemic PE-specific IgG and IgE responses. Following peanut challenge via the IP route, both TS- and IP-sensitized pigs displayed allergy symptoms, including lethargy, skin rashes, vomiting, and a drop in body temperature. However, respiratory distress was observed exclusively in pigs sensitized through the TS route and not in those sensitized through the IP route. However, it is noteworthy that both groups of sensitized pigs maintained peanut hypersensitivity for up to two months post-sensitization, albeit with a reduction in the severity of allergy symptoms. Importantly, both groups exhibited sustained levels of PE-specific IgG, IgE, and elevated concentrations of mast cell protease in their blood following the IP challenges. Discussion: Overall, this study reports TS and IP as two different modes of sensitization leading to onset of peanut specific allergic reactions in mini pigs, but only the TS-sensitization led to systemic anaphylaxis (simultaneous presence of symptoms: breathing difficulty, intense skin rash, and impaired mobility). A distinctive feature of these sensitization protocols is the 100% success rate (N = 4 pigs per group) in sensitizing the subjects.

    Distraction and visual search characteristics of young drivers when using navigation system displays
    (2024) Yared, Tamer; Patterson, Patrick (TTU); Mumani, Ahmad
    Navigation systems are fast and efficient sources of road information for drivers. However, they can increase the potential for accidents by distracting drivers. This study investigated the impact of navigation systems on driver distraction and visual search under various driving conditions. Using a driving simulator, eye-tracking technology recorded visual search data from twenty young drivers. The experiment analyzed factors such as driving environment (urban and rural), illumination level (day and night), and navigation system display size (large and small), as well as their interactions. Multiple eye movement metrics were employed, including duration and frequency of GPS fixation, dwell duration on the road ahead, and dwelling on mirrors and side windows. Statistical analysis employed repeated measures ANOVA to analyze the data. Findings revealed that small GPS displays caused greater distraction in terms of average and total gaze duration. Additionally, distraction increased during daytime driving conditions. In terms of visual search, wider and more dispersed search patterns were observed during the day, resulting in improved driving performance. This study aims to compare small and large navigation displays to identify the more effective option in reducing driver distractions. The research contributes to understanding driver distraction and visual search when using navigation system displays.

    Global photosynthetic capacity jointly determined by enzyme kinetics and eco-evo-environmental drivers
    (2024) Yan, Zhengbing; Detto, Matteo; Guo, Zhengfei; Smith, Nicholas G. (TTU); Wang, Han; Albert, Loren P.; Xu, Xiangtao; Lin, Ziyu; Liu, Shuwen; Zhao, Yingyi; Chen, Shuli; Bonebrake, Timothy C.; Wu, Jin
    Accurate understanding of global photosynthetic capacity (i.e. maximum RuBisCO carboxylation rate, Vc, max) variability is critical for improved simulations of terrestrial ecosystem photosynthesis metabolisms and carbon cycles with climate change, but a holistic understanding and assessment remains lacking. Here we hypothesized that Vc, max was dictated by both factors of temperature-associated enzyme kinetics (capturing instantaneous ecophysiological responses) and the amount of activated RuBisCO (indexed by Vc, max standardized at 25 ℃, Vc, max25), and compiled a comprehensive global dataset (n = 7339 observations from 428 sites) for hypothesis testing. The photosynthesis data were derived from leaf gas exchange measurements using portable gas exchange systems. We found that a semi-empirical statistical model considering both factors explained 78% of global Vc, max variability, followed by 55% explained by enzyme kinetics alone. This statistical model outperformed the current theoretical optimality model for predicting global Vc, max variability (67%), primarily due to its poor characterization on global Vc, max25 variability (3%). Further, we demonstrated that, in addition to climatic variables, belowground resource constraint on photosynthetic machinery built-up that directly structures the biogeography of Vc, max25 was a key missing mechanism for improving the theoretical modelling of global Vc, max variability. These findings improve the mechanistic understanding of global Vc, max variability and provide an important basis to benchmark process-based models of terrestrial photosynthesis and carbon cycling under climate change.

    Online University Students’ Perceptions of institution and Program Community and the Activities that Support Them
    (2024) Shepherd, Craig E.; Bolliger, Doris U. (TTU); McKim, Courtney
    The twenty-eight item Sense of Online Community Scale was completed by 293 online students at a midsized southeastern United States university to ascertain community importance and activities associated with its formation and maintenance on the program and institutional level. A large majority of these students believed that a sense of community was important and that a sense of belonging, affiliation, and trust were valuable for community formation. Participants also believed that program and institutional activities, both academic and social, played key roles in community formation. However, academic activities (e.g., advising, program milestones, writing centers, library support) were rated as more influential than social activities (e.g., get-togethers, online games, institution sporting events). When demographic characteristics were considered, non-White participants rated their sense of affiliation with their program/institution higher than White participants. Participants who lived within a one-hour commute to campus (51% of our sample) rated institutional social activities higher than those who lived farther out. Doctoral students rated program activities as more conducive to community formation than masters, and graduate certificate students and undergraduate students rated affiliation to their program/institution higher than master’s and graduate certificate students.

    Parental control and college students’ depressive symptoms: A latent class analysis
    (2024) Hwang, Woosang (TTU); Jung, Eunjoo; Hadi, Narges (TTU); Kim, Seonghee
    We examined how maternal and paternal parental control (helicopter parenting, behavioral control, and psychological control) among college students are related to their depressive symptoms. We collected data from college students who attended a private university in Upstate New York (n = 455) and analyzed it using three-step latent class analysis. Latent class analysis identified four parental control latent classes: weak parental control, strong psychological control, strong helicopter parenting, and strong parental control. College students in the weak parental control class reported lower depressive symptoms than those in strong psychological control and strong parental control classes. In addition, college students in the strong helicopter parenting class reported lower depressive symptoms than those in strong psychological control and strong parental control classes. College students’ depressive symptoms were not significantly different between weak parental control and strong helicopter parenting classes. Future researchers are encouraged to continue to acknowledge the characteristics of different forms of parental control and their influence on college students’ quality of life in the transition to adulthood, considering the unique approaches of both parents.
