Article Abstract
Objective: Converging evidence indicates large magnitude deficits in the "working" component of working memory for children with ADHD. However, our understanding of the relation between these central executive deficits and ADHD behavioral symptoms remains limited due to problems with several commonly used working memory tests.
Method: Children with ADHD ( = 25) completed a counterbalanced series of working memory tasks that differed only in memory set predictability.
Results: Results indicated that central executive demands increased when memory set was unpredictable, as evidenced by moderate performance decreases ( = 0.22-0.56) and large changes in performance variability ( = 0.93-3.16) and response times ( = 1.74-4.16). Activity level remained relatively stable when memory set was unpredictable but decreased significantly over time when memory set was predictable.
Conclusion: Results suggest that altering memory set predictability is a feasible method for increasing/maintaining central executive demands over time, and suggest a positive association between working memory demands and gross motor activity for children with ADHD.

Nuclear paxillin functions as a molecular switch for alternative splicing in neurons during a critical period of brain development.

During a critical period of postnatal brain development, neural circuits undergo significant refinement coincident with widespread alternative splicing of hundreds of genes, which undergo altered splice site selection for the generation of isoforms essential for synaptic plasticity. Here, we reveal that neuronal activity-dependent phosphorylation of paxillin at its serine 119 (p-paxillin) acts as a molecular switch in the nucleus for the control of alternative splicing during this period. We show that following NMDA receptor activation, nuclear p-paxillin is recruited to nuclear speckles, where it interacts with splicing factors, such as U2AFs.

Additionally, prior work has found a relatively negligible role of head movements associated with performance costs.

Negative symptoms, depression, and cognitive impairments of the schizophrenia spectrum have been associated with difficulties in daily functioning. Compensatory Cognitive Training (CCT) has shown positive effects on cognition, negative symptoms, and functioning in this population. The main objective of this pilot study was to analyze the effects of CCT on cognition and functioning in a group schizophrenia spectrum outpatients in Mexico.

In recent years, there has been a significant increase in minors with gender dysphoria (GD) seeking transition treatments, including puberty blockers and cross-sex hormones. The developing child's brain exhibits structural and functional differences in children with GD compared to cisgender children, particularly in areas where sex differences exist. Brain development during childhood and adolescence is strongly influenced by sex hormones.

The increasing dependence on cloud computing as a cornerstone of modern technological infrastructures has introduced significant challenges in resource management. Traditional load-balancing techniques often prove inadequate in addressing cloud environments' dynamic and complex nature, resulting in suboptimal resource utilization and heightened operational costs. This paper presents a novel smart load-balancing strategy incorporating advanced techniques to mitigate these limitations.
