Objective: The vast majority of children with an autism spectrum disorder (ASD) attend public preschools at some point in their childhood. Community preschool practices often are not evidence based, and almost none target the prelinguistic core deficits of ASD. This study investigated the effectiveness of public preschool teachers implementing a validated intervention (the Joint Attention and Symbolic Play/Engagement and Regulation intervention; JASP/ER) on a core deficit of autism, initiating joint attention.
Method: Sixteen dyads (preschoolers with ASD and the public school teachers who worked in the child's classroom) were randomly assigned to the 6-week JASP/ER intervention or a control group.
Results: At the end of the intervention, JASP/ER teachers used more JASP/ER strategies than the control teachers, and JASP/ER preschoolers used more joint attention in their classroom than control children. Additionally, JASP/ER children spent more time in supported engagement and less time in object engagement than control preschoolers on a taped play interaction.
Conclusions: Findings suggest that teachers were able to improve a core deficit of children with ASD in a public preschool context.

Flexible tactile sensors have received significant attention for use in wearable applications such as robotics, human-machine interfaces, and health monitoring. However, conventional tactile sensors face challenges in accurately measuring pressure because vertical deformation is induced by Poisson's ratio in situations where lateral strain is applied. This study shows a strain-insensitive flexible tactile sensor array without the crosstalk effect using a highly stretchable mesh.

Background And Objective: The hybrid brain computer interfaces (BCI) combining electroencephalogram (EEG) and functional near-infrared spectroscopy (fNIRS) have attracted extensive attention for overcoming the decoding limitations of the single-modality BCI. With the deepening application of deep learning approaches in BCI systems, its significant performance improvement has become apparent. However, the scarcity of brain signal data limits the performance of deep learning models.

The occurrence and development of tumor is mediated by a wide range of complex mechanisms. Subsequent to nitric oxide and carbon monoxide, hydrogen sulfide (HS) holds the distinction of being the third identified gasotransmitter. Alternation of HS level has been widely demonstrated to induce an array of disturbances in important cancer cell signaling pathways.

The Covid-19 pandemic has sparked renewed attention to the risks of online misinformation, emphasizing its impact on individuals' quality of life through the spread of health-related myths and misconceptions. In this study, we analyze 6 years (2016-2021) of Italian vaccine debate across diverse social media platforms (Facebook, Instagram, Twitter, YouTube), encompassing all major news sources-both questionable and reliable. We first use the symbolic transfer entropy analysis of news production time-series to dynamically determine which category of sources, questionable or reliable, causally drives the agenda on vaccines.

Low tumor enrichment remains a serious and urgent problem for drug delivery in cancer therapy. Accurate targeting of tumor sites is still a critical aim in cancer therapy. Though there have been a variety of delivery strategies to improve the tumor targeting and enrichment, biological barriers still cause most delivered guests to fail or be excreted before they work.
