Effects of psychological arousal and relaxation on muscle performance, activation, and heart rate variability during maximal muscle strength and precision tasks
Get PDFPsychological arousal plays a vital role in athletic performance, with the optimal point of arousal and performance level varying by task complexity. A common manipulator of arousal is music, which can produce multiple physiological effects. This study investigated whether unfamiliar arousing or relaxing music influences heart rate variability, muscle activation, maximal muscle strength, and muscle precision. Theoretically, if participants are found to have differing muscle performance responses as a result of differing music selections, this would further support the notion that the optimal point of arousal and performance is dependent upon the complexity of the task at hand. Thus, coaches and exercise professionals might consider adjusting athletes’ environments to produce a psychological arousal level appropriate for the type of task demanded
Investigation of guayule resin as an oil-based wood treatment
No full textDevelopment of alternative treatments for wood product protection is an ongoing focus throughout the wood products industries. All manufacturers hope to increase the use life of their products, while ensuring that their products do not have a harmful impact on their surrounding environment. One way of approaching this is to source potential components from other agricultural sources. Guayule resin is produced as a by-product of rubber extraction from the guayule plant (Parthenium argentatum). The resin has been reported to have insecticidal and microbial properties, but there are numerous problems with utilization, including how to extract it and apply it due to its very thick consistency. Recent testing has determined that it can be blended with some oil-based products. During this project, we will mix the guayule resin with various oils that have antibacterial and antifungal properties to create a new way of applying the resin to wood products along with determining whether applying the resin enhances wood protection
Reactive molecular dynamics and method development for applications in renewable energy and sorption equilibria
No full textIt is crucial to harness energy from sustainable sources to combat the dwindling nonrenewable feedstocks used to produce everyday commodities and fuels. Liquid-phase heterogeneous catalysis has demonstrated remarkable product selectivity and yields for reactions relevant to biomass valorization under mild operating conditions. However, active site characterization is challenging due to the complex solvated environment and interface. Ground-state first-principles (FP) molecular simulations have provided insights into reactive systems in catalysis. These calculations, however, scale poorly with the number of electrons. Observing atomic motion with molecular dynamics (MD) or sampling static properties with Monte Carlo (MC) simulations at statistically relevant lengths- and timescales are not computationally tractable from first principles. A faster approach to FP calculations that retains the underlying potential energy surface is necessary to enable a high throughput understanding of reactive phenomena at an atomic resolution and to search for optimal catalyst properties and operating conditions. Machine-learned interatomic potentials (MLIPs) can serve as a surrogate model for first principles (FP) calculations, enabling large-scale simulations of complex systems. In this research, we first explore the interaction between methanol and water with the surface of a Brønsted acid MWW zeolite nanosheet, using FP-MD to illustrate the need for MLIPs. Next, we show that MLIPs can be utilized to elucidate the nature of transition metal surface active sites and capture environmental effects by simulating hydrogen dissociation over molybdenum carbide polymorphs. We also apply these methods to study solvent interactions with open and closed-site Sn-BEA zeolites. Finally, we integrate MC subroutines into the Atomic Simulation Environment to enable FP Grand Canonical Monte Carlo (MC) and MC with machine-learned interatomic potentials. The research presented here illustrates that MLIPs can be utilized to simulate complex catalytic systems, retaining the underlying ab initio potential energy surface. We also provide the scientific community access to an open-source framework for FP Grand Canonical Monte Carlo simulations
TopNet R1: A multi-stage AI framework for topic discovery in scientific abstracts
No full textScientific abstracts are rich sources of knowledge, yet extracting meaningful topics remains challenging due to limitations in existing topic modeling techniques. Traditional methods often struggle with interpretability, scalability, and contextual understanding. To overcome these issues, we introduce TopNet R1, a multi-stage ensemble framework that integrates traditional topic models with contextual embeddings from Bidirectional Encoder Representations from Transformers (BERT) and Generative Pre-trained Transformer 4 (GPT-4) large language models (LLMs). Top- Net R1 operates in three phases: (1) topic generation using Latent Dirichlet Allocation (LDA), Non-Negative Matrix Factorization (NMF), Latent Semantic Analysis (LSA), and Hierarchical Dirichlet Process (HDP); (2) LLM-assisted pattern recognition to refine and interpret topics; and (3) validation via mixed-effects regression. This design improves semantic coherence and diversity while maintaining efficiency. We evaluated TopNet R1 on PubMed and arXiv, where it outperformed traditional models in coherence (C_v, C_UMass) and diversity (C_TD), achieving C_v = 0.6189 and C_UMass = −2.94 on PubMed
