Abstract:

The seawater temperature is important that affects marine ecosystems and marine life. This paper aimed to analyze the main factors that affect seawater temperature using Bottle Database collected at California Cooperative Oceanic Fisheries Investigations stations. The dataset contained seawater samples collected using bottles. Linear regression was performed using temperature as the dependent variable and depth, salinity, oxygen, and potential density as independent variables. Stepwise methods were used to select variables for regression models. To determine the most influential factor affecti

Abstract:

In this study, we employed various machine learning-based techniques in predicting factor of safety against slope failures. Different regression methods namely, multi-layer perceptron (MLP), Gaussian process regression (GPR), multiple linear regression (MLR), simple linear regression (SLR), support vector regression (SVR) were used. Traditional methods of slope analysis (e.g., first established in the first half of the twentieth century) used widely as engineering design tools. Offering more progressive design tools, such as machine learning-based predictive algorithms, they draw the attention

Abstract:

Objective: Clinical heterogeneity in major depressive disorder likely reflects the range of etiology and contributing factors in the disorder, such as genetic risk. Identification of more refined subgroups based on biomarkers such as white matter integrity and lipid-related metabolites could facilitate precision medicine in major depressive disorder. Methods: A total of 148 participants (15 genetic high-risk participants, 57 patients with first-episode major depressive disorder and 76 healthy controls) underwent diffusion tensor imaging and plasma lipid profiling. Alterations in white matter i

Abstract:

Abstract Background and Aims Stroke is a significant global health issue, representing the second leading cause of death and a major contributor to disability. It can be classified into two main types: ischemic stroke, caused by blockage of a brain blood vessel, and haemorrhagic stroke, resulting from blood vessel rupture. Chronic kidney disease (CKD) is another prevalent health concern, affecting approximately 10% of all populations worldwide. CKD impairs kidney function and has been associated with an increased risk of cerebrovascular events, including stroke. Within the Northern Thai popula

Abstract:

Context: Excessive hip adduction and internal rotation are abnormal movements that may lead to the onset and progression of patellofemoral pain. Previous studies have reported that lower dynamic frontal plane hip joint stiffness in the gait of women is associated with the magnitude of hip adduction and internal rotation angles. However, the factors contributing to the lack of dynamic frontal plane hip joint stiffness in the gait of young women are unclear. This study aims to investigate the factors affecting dynamic frontal plane hip joint stiffness during the weight-acceptance phase of the ga

Abstract:

BACKGROUND: Hypertension is the most potent stroke risk factor and is also related to cerebral small vessel disease. We studied the relation between mid-to-late-life hypertension trends and cerebral white matter injury in community-dwelling individuals from the FHS (Framingham Heart Study). METHODS: FHS Offspring cohort participants with available mid-life and late-life blood pressure measurements and brain magnetic resonance imaging were included. Multiple regression analyses were used to relate hypertension trends (normotension-normotension [reference], normotension-hypertension, and hyperte

Abstract:

Abstract Background Overweight and obesity are related to the risk of new-onset atrial fibrillation (AF). Peak atrial longitudinal strain (PALS) is an advanced echocardiographic parameter of left atrial (LA) function with a recognized diagnostic and prognostic role in both the general population and AF. Purpose To investigate the impact of body mass index (BMI) on LA function by utilizing standard and advanced echocardiography in patients with non-valvular AF. Methods In the NeAfib-Echo registry, 395 consecutive adult patients with non-valvular AF (F/M: 175/220; mean age 70.6 ± 11 years, BMI:
