Tulip contacts are widely used in power systems due to their high reliability. However, with the increase of operation years and the cyclic variation of boundary loads, their contact parts are prone to degradation, leading to overheating faults. Temperature rise, as a key parameter characterizing the evolution of thermal faults, is commonly used to monitor the contact state of switchgear. The GC 5-630 tulip contact is taken as the research object. A three-dimensional electro-thermal-mechanical multiphysics coupling model is established based on the finite element analysis method to analyze the influence laws of different factors on the temperature rise of the …

Lqr Control Based On Ga Optimization For Suppressing Power Oscillations In Fractional-Order Vsg, Jun Zhu, Zhengbin Chen, Jiantang Chen, Haozhuo Wei, Penghui Liu, Ming Yang

Journal of Electric Power Science and Technology

A linear quadratic regulator (LQR) optimized based on the genetic algorithm (GA) was designed to suppress power oscillations in a virtual synchronous generator (VSG) under external disturbances. A state-feedback LQR controller was designed by establishing a small-signal model of the VSG power loop. To optimize the control performance, the GA was used to perform offline optimization of the weight-matrix parameters of LQR. The weight-optimized LQR control law was applied to the fractional-order VSG. The simulation results show that, compared with traditional VSG control, the proposed control strategy can effectively suppress power oscillations, reducing the oscillation overshoots of active and reactive …

Chemistry Faculty Research & Creative Works

Enzymatic electrochemistry harnesses the selectivity of enzymes to enable electrochemical applications spanning sensing, synthesis, and energy conversion. However, the sequential nature of electroanalytical experiments limits throughput, restricting the scale at which enzyme-electrode systems can be screened. Here we demonstrate the capabilities of an automated electrochemistry platform, eLab, to increase the throughput of enzymatic electrochemistry investigations. We used the eLab to collect over 10,000 cyclic voltammograms across a large parameter space consisting of two enzyme variants (promiscuous and wild-type glucose oxidase), 20 saccharide substrates, 21 concentrations, and four scan rates, with measurements being made all in triplicate. The expansive dataset enabled …

Implications Of Weather Variability On Corn Yield In The U.S., Gideon Ayettey

LSU Master's Theses

Climate variability is a major source of risk to U.S. crop production, disrupting planting schedules and threatening yields. While prior research has explored the implications of weather shocks on crop yields, this study investigates the indirect channel via which weather variability impacts corn yield through planting delays in the U.S. Previous research has shown that U.S. corn production is highly vulnerable to short-term climate variability (Hu & Buyanovsky, 2003). We use county-level data from 2015 to 2024 for the top five corn-producing states and use a 2-stage least squares method to measure the effect. However, in our specification, planting day …

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Background: Hypoglossal nerve stimulation (HNS) is an established surgical therapy for adults with moderate-to-severe obstructive sleep apnea (OSA) who are intolerant to positive airway pressure. Although aggregate response rates of ~70–80% have been reported, substantial variability across clinical settings remains poorly understood. Prior meta-analyses have largely emphasized pooled continuous outcomes, limiting interpretation of responder-based endpoints and drivers of between-study heterogeneity. Methods: A PRISMA-compliant systematic review and meta-analysis was performed. MEDLINE, Embase, and Cochrane CENTRAL were searched from inception through 31 December 2025. Eligible studies enrolled adults with OSA treated with implantable HNS, reported Sher-defined response (≥50% AHI reduction and residual …

Perspective On Lessons Not Learned: From Coley’S Toxins To Microbial Drug Delivery, Guidance For Institutional Review Boards (Irbs), Brian P. Hanley, Alejandro J. Betancourt, Gustavo Gross, Wilbur (Bo) Bowne

School of Medicine Publications

The bacterial and toxin methods of cancer treatment date back 130 years. This paradigm rests on nonspecific bacterial-toxin-generated immunotherapy. This high-risk oncology research is experiencing a renaissance of methods that are among the most effective yet. Glioblastomas and other resistant cancers are the modern touchpoint, because of remission history following sepsis. Spurred by recent research deaths, we discuss protocols IRBs should consider in live bacterial or synthetic immuno-stimulatory trials. Human systemic inflammatory response syndrome immunology is unique due to non-functioning SIGLEC-13 and 17, which control excessive Toll-like receptor 4 (TLR-4) signaling. This is not a technicality like human CD8+/CD4+ T …

Ai-Driven Detection Of Neurodevelopmental Disorder From Emotional Speech Using A Hybrid Cnn–Bilstm–Attention Framework, Nayarah Shabir, Parveen Lehana, Sheema Khan

School of Medicine Publications

Neurodevelopmental disorders (NDDs) are associated with impairments in communication, behavior, and social interaction, making accurate diagnosis clinically challenging. Autism Spectrum Disorder (ASD), a major NDD, often exhibits atypical speech patterns characterized by altered prosody and reduced emotional expressiveness. The study proposes a hybrid dual-path framework for ASD detection from emotional speech using two strategies: PCA–GMM-based acoustic modeling and a CNN–BiLSTM–Attention architecture for spectral–temporal feature learning. The proposed framework captures probabilistic, spectral, and temporal speech characteristics for robust ASD classification. Acoustic analysis demonstrated clear separability between ASD and non-ASD speech, while the deep learning framework achieved stable and reliable performance across …
