Performance enhancement of a wind driven PMSG using an artificial neural network based nonlinear backstepping controller.

With the increasing demand for wind energy in the electric power generation industry, optimizing robust and efficient control strategies is essential for a wind energy conversion system (WECS). In this regard, this study proposes a novel hybrid control strategy for wind power systems directly coupled to a permanent-magnet synchronous generator (PMSG). The contribution of this work is to propose a control strategy design based on a combination of the nonlinear Backstepping approach for system stabilization according to Lyapunov theory and the application of artificial neural network to maximize energy harvesting regardless of wind speed fluctuations.

Therapeutic Effect of Physical Activity in a Male Wistar Rat Model of Paraquat and Maneb-Induced Parkinson's Disease.

Parkinson's disease (PD) is characterized by impairments in motor control following the degeneration of dopamine-producing neurons located in the substantia nigra pars compacta. Environmental pesticides such as Paraquat (PQ) and Maneb (MB) contribute to the onset of PD by inducing oxidative stress (OS). This study evaluated the therapeutic efficacy of moderate physical activity (PA) on both motor and non-motor symptoms in a Wistar rat model of Paraquat and Maneb (PQ/MB) induced PD.

Emerging SARS-CoV-2 variants: genomic shifts, immune evasion, and therapeutic perspectives.

The COVID-19 pandemic, caused by the continuously evolving SARS-CoV-2 virus, has presented persistent global health challenges. As novel variants emerge, many with enhanced transmissibility and immune evasion capabilities, concerns have intensified regarding the efficacy of existing vaccines and therapeutics. This review provides a comprehensive overview of the current landscape of COVID-19 vaccination, including the development and performance of monovalent and bivalent boosters, and examines their effectiveness against newly emerging variants of interest (VOIs) and variants under monitoring (VUMs), such as JN.

Search Methods: We searched MEDLINE, Scopus, the Cochrane Central Register of Controlled Trials (CENTRAL), and the World Health Organization (WHO) Global Index Medicus from inception to 11 December 2023 without restrictions.

A rare case of duodenojejunal intussusception causing biliary obstruction during pregnancy.

Intussusception is an uncommon cause of intestinal obstruction in adults and rarely encountered during pregnancy. Duodenal intussusception is particularly rare due to the fixed position of the duodenum. We report a unique case of duodenojejunal intussusception in a pregnant woman at 28 weeks of gestation, who presented with symptoms mimicking acute pancreatitis complicated by biliary tract obstruction.

On the use and misuse of time-rescaling to assess the goodness-of-fit of self-exciting temporal point processes.

The paper first highlights important drawbacks and biases related to the common use of time-rescaling to assess the goodness-of-fit (Gof) of self-exciting temporal point process (SETPP) models. Then it presents a new predictive time-rescaling approach leading to an asymptotically unbiased Gof framework for general SETPPs in the case of single observed trajectories. The predictive approach focuses on forecasting accuracy and addresses the bias problem resulting from the plugged-in estimated parameters.

The associations between floral traits and pollinator groups in two Mediterranean mountainous plant communities in the Middle Atlas of Morocco.

Background: The relationships between floral traits and pollinators have been extensively studied over the last few decades. The concept of pollination syndrome suggests that plants pollinated by the same group of pollinators tend to develop similar combinations of floral traits. However, several studies have demonstrated the low predictability of these trait combinations and found high levels of pollination generalization within plant communities.

Dual-functional hydrochar via hydrothermal carbonization for norfloxacin removal: Fractal adsorption kinetics and mechanism elucidation.

Escalating concentrations of norfloxacin (NFX) in surface and wastewaters demand sustainable remediation strategies. In this study, dual-functional hydrochars were synthesized from argan nut shells (ArNS) via hydrothermal carbonization (HTC), with process conditions optimized by varying temperature (150-200 °C) and residence time (2-6 h). Among the materials, H1:5@150-4-prepared at 150 °C for 4 h with a biomass-to-water ratio of 1:5-exhibited the best performance, achieving a monolayer NFX adsorption capacity of 27.

Hypnosis to improve life quality in invasive mole: a case report.

Gestational trophoblastic tumors (GTTs) encompass a spectrum of neoplastic conditions, including invasive mole, choriocarcinoma, placental site trophoblastic tumor, and epithelioid trophoblastic tumor. Invasive mole, which frequently develops following a complete hydatidiform mole, represents the most common form. A cancer diagnosis constitutes a profoundly destabilizing experience, often resulting in considerable psychological distress.

The Tubotomaculum Enigma and the Rise of Benthic Life During the Opening of the Western Mediterranean Basin.

Large-scale geological processes shape microbial habitats and drive the evolution of life on Earth. During the Oligocene, convergence between Africa and Europe led to the opening of the Western Mediterranean Basin, a deep-ocean system characterized by fluid venting, oxygen depletion, and the absence of benthic fauna. In this extreme, inhospitable seafloor environment, fusiform objects known as Tubotomaculum formed, whose origin has long remained controversial.

Reperfusion Therapy for ST Elevation Myocardial Infarction in Low to Middle-Income Countries. A Clinical Consensus Statement of the Association for Acute CardioVascular Care (ACVC), the European Association of Percutaneous Cardiovascular Interventions (EAPCI), the European Association of Preventive Cardiology (EAPC), the ESC Working Group on Thrombosis, and the Stent - Save a Life! Initiative.

Suboptimal care for ST-elevation myocardial infarction (STEMI) in low- and middle-income countries is a significant problem. Registries from Latin America, Africa, and Asia show that less than 65% of patients receive reperfusion therapy, and widespread treatment delays and a lack of access to optimal therapies lead to preventable deaths and complications. While current guidelines provide a blueprint for care, their implementation in low-resource settings requires specific guidance that considers geographical, logistical, and economic realities.
