Application of machine learning and neural network models based on experimental evaluation of dissimilar resistance spot-welded joints between grade 2 titanium alloy and AISI 304 stainless steel.

The use of a composite welded joint consisting of titanium and austenitic stainless steel metals is evidently a favourable selection for industrial applications employing the resistance spot welding (RSW) operation. Nevertheless, achieving a high-quality welded joint proved challenging owing to the properties of the diverse range of materials' used. To improve the quality of dissimilar welded joints, the welding parameters should be selected precisely.

Inequalities in geographic barriers and patient representation in lymphoma clinical trials across England.

The distribution of trial site locations may lead to disparities in geographic access and affect patient representativeness in clinical trials. We utilised trial data covering 1993-2022 from the National Institute for Health and Care Research (NIHR) Open Data Platform, 2011 and 2021 English Census and geographic data and English individual-patient cancer registry data for patients diagnosed with lymphoma between 1997 and 2017. To assess representation, we compared patient age and sex between trial participants and the incident population.

Predictors of Unplanned Health Care Utilization Among Children with Inflammatory Bowel Disease in a Rural Region of the Southeastern US.

Background: Pediatric Inflammatory Bowel Disease (IBD) imposes significant healthcare costs and strains emergency services. This study aimed to identify factors associated with unplanned healthcare usage among children with IBD in a rural, medically underserved region in the southeastern United States.

Methods: In this retrospective cohort study, we analyzed children (<18 years) with moderate or severe IBD followed at an academic pediatric gastroenterology clinic between 2016 and 2021.

Single-Atomic Co-N Sites with CrCo Nanoparticles for Metal-Air Battery-Driven Hydrogen Evolution.

Designing highly active and robust earth abundant trifunctional electrocatalysts for energy storage and conversion applications remain an enormous challenge. Herein, we report a trifunctional electrocatalyst (CrCo/CoN@CNT-5), synthesized at low calcination temperature (550 °C), which consists of Co-N single atom and CrCo alloy nanoparticles and exhibits outstanding electrocatalytic performance for the hydrogen evolution reaction, oxygen evolution reaction, and oxygen reduction reaction. The catalyst is able to deliver a current density of 10 mA cm in an alkaline electrolytic cell at a very low cell voltage of ∼1.
