Abstract Aiming at the difficulty of wind power prediction due to volatility and uncertainty generation, this paper proposes a hybrid model based on Convolutional Neural Network (CNN) Bidirectional Long Short-Term Memory (BiLSTM), optimises hyper-parameters using Bayesian Optimization Algorithm (BO) in order improve accuracy. Firstly, input features that are highly correlated with screened Pearson Coefficient method (PCC). Then, CNN is used extract from data. Next, extracted by further...

Exploring efficient and stable solution methods for hydropower generation optimization models is crucial enhancing reservoir power efficiency achieving the sustainable use of water resources. However, existing studies predominantly focus on single-timescale scheduling models, failing to fully exploit multi-timescale runoff information. Additionally, commonly used algorithms often face challenges such as premature convergence, susceptibility local optima, dimensionality issues. To address...

The effect of transplanted rat mesenchymal stem cells (MSCs) can be reduced by extracellular microenvironment in myocardial infarction (MI). We tested a novel small-molecular hydrogel (SMH) on whether it could provide scaffold for hepatocyte growth factor (HGF)-modified MSCs and alleviate ventricular remodeling while preserving cardiac function after MI. Overexpression HGF increased Bcl-2 Bax caspase-3 levels response to hypoxia vitro. Immunocytochemistry demonstrated that troponin (cTnT),...

Background: The retear rate after revision rotator cuff repair (rRCR) ranges from 50% to 90%. Patients who undergo primary RCR (pRCR) for large massive tear (mRCT) also have unpredictable outcomes. Purpose: To compare the clinical outcomes rRCR a posterosuperior of any size with those pRCR mRCT and identify risk factors poor rRCR. Study Design: Cohort study; Level evidence, 3. Methods: Among patients treated between 2010 2017, 46 underwent were compared 106 mRCT. Between-group differences in...

Abstract Microribonucleic acids (miRNAs) are essential for the regulation of development, proliferation, and functions pancreatic β-cells. The conserved miR-221/222 cluster is an important regulator in multiple cellular processes. Here we investigated functional role β-cell proliferation transgenic mouse models. We generated 2 β-cell-specific–miR-221/222 models on a C57BL/6J background. glucose metabolic phenotypes, mass, were analyzed Adenovirus-mediated overexpression was performed β-cells...

Myocardial necrosis after ST-segment elevation myocardial infarction (STEMI) can cause left ventricular systolic dysfunction, which has been associated with poor outcomes. Some authors have reported that women higher mortality rates primary percutaneous coronary intervention (PCI), but differences between the sexes regard to recovery of ejection fraction (EF) in patients STEMI receiving PCI not evaluated. We aimed assess effect sex on EF anterior wall PCI.A total 202 consecutive (134 men)...

Ischemic stroke is the most common cerebrovascular disease, and vascular obstruction an important cause of this disease. As main method for management carotid artery stenosis, endarterectomy (CEA) effective preventive treatment measure in ischemic This study aims to propose application a new enhanced recovery after surgery (ERAS) nutritional support regimen CEA, which can significantly improve perioperative status patients. A total 74 patients who underwent CEA were included randomly divided...

Quantitative computed tomography-based finite element analysis (QCT/FEA) has been developed to predict vertebral strength. However, QCT/FEA models may be different with scan resolutions and sizes. The aim of this study was explore the effects sizes on outcomes. Nine bovine bodies were scanned using clinical CT scanner reconstructed from datasets two-slice thickness, that is, 0.6 mm (PA resolution) 1 (PB resolution). There significantly linear correlations between predicted measured principal...

Synovial osteochondromatosis (SOC) of the shoulder is a rare condition with unclear characteristics. This study evaluated clinical features and postoperative functional outcomes SOC that are distinct from other joints.The characteristics 28 shoulders underwent arthroscopy were retrospectively assessed. Ten (35.7%) had rotator cuff tears (RCTs) concomitant arthroscopic repair. The mean follow-up period was 83.6 months (range, 24-154 months). Demographic loose bodies localized under compared...
