Background: Physical activity interventions positively influence executive functions in both the general population and individuals with ADHD. However, there is limited research focusing on school-aged children, who have the highest ADHD diagnosis rates. This study aims to provide targeted intervention strategies for improving executive function in this population, offering a practical reference for selecting specific exercise types when designing interventions for children with ADHD.

Article Synopsis
  • The paper discusses how the direction-of-arrival (DOA) estimation for sonar on an unmanned underwater vehicle (UUV) can be affected by interference from both nearby and distant sources.
  • It introduces a sparsity-based DOA estimation method that separates weak far-field signals from near-field interferences using sparse reconstruction techniques.
  • The method also incorporates subspace projection to improve the estimation of weak target signals that are masked by strong interferences, showing better performance in simulations and experiments compared to other advanced estimation methods.

Background: Perinatal depression can have profound impacts on both families and society. Exercise therapy is gradually becoming a widely used adjunct treatment for perinatal depression. Some studies have already focused on the relationship between physical activity and perinatal depression (PND).

Attention problems are one of the core symptoms of Attention-deficit/hyperactivity disorder (ADHD) in children. Previous studies have shown that physical activity intervention has a positive impact on executive function in children and adolescents with ADHD, but there is limited research on attention problems in school-aged children with ADHD. There are still uncertainties about the appropriate physical activity interventions to improve attention problems in this population.

The physical and psychological benefits of physical activity are well established. However, there is no consensus regarding the effects of physical activity on children's academic performance in general and in specific subjects. We conducted this systematic review and meta-analysis to identify forms of physical activity that are suitable for improving the physical activity levels and academic performance of children aged 12 years and under.

Background: Previous studies have shown that physical activity interventions positively affect core symptoms and executive functioning in children with attention-deficit/hyperactivity disorder (ADHD). However, comparisons between different physical activity interventions still need to be made. This study is the first to analyze the effects of 10 different types of physical activity on children with ADHD through a network meta-analysis.

Target direction-of-arrival (DOA) estimation is often difficult in the presence of strong interference-especially when the target DOA is very close to the interference DOA-since the strong interference signal can mask the weak target signal and make the DOA estimation hard. To address this problem, an efficient sparse method for DOA estimation is proposed in this paper, in which the effect of strong interference on the target DOA estimation is significantly reduced. An on-grid version of the grid evolution technique is then developed to nonuniformly refine the grid, thereby reducing the computational complexity while retaining reasonable accuracy.
