Estimating the axial strain of circular short columns confined with CFRP under centric compressive static load using ANN and GRA techniques.

This investigation introduces advanced predictive models for estimating axial strains in Carbon Fiber-Reinforced Polymer (CFRP) confined concrete cylinders, addressing critical aspects of structural integrity in seismic environments. By synthesizing insights from a substantial dataset comprising 708 experimental observations, we harness the power of Artificial Neural Networks (ANNs) and General Regression Analysis (GRA) to refine predictive accuracy and reliability. The enhanced models developed through this research demonstrate superior performance, evidenced by an impressive R-squared value of 0.

Diglossia Correlates With Prodromal Symptoms of Psychosis Among First-Generation Migrants.

Background And Hypothesis: We have previously hypothesized that diglossia may be a risk factor for psychosis, drawing from observations on migration, ethnicity, social adversity, and language disturbances among others. However, empirical data on this association and the tools necessary for its measurement are limited.

Study Design: In a cross-sectional online sample of first-generation migrants residing in majority English-speaking countries, a response-based decision tree was introduced to classify the sociolinguistic profiles of 1497 participants as either with or without diglossia.

Knowledge and practice regarding contact lens among Saudi urban contact lens users.

Purpose: To assess the level and determinants of knowledge and practice regarding contact lens (CL) and its accessories among adult Saudi CL users.

Methods: This survey was conducted in 2015 for Saudi contact lens users visiting a Mall in Riyadh, Saudi Arabia. The questions were related to knowledge about contact lenses, correct CL and accessories usage.
