Traditional 3D reconstruction models have consistently faced the challenge of balancing high recall of object edges with maintaining a high precision. In this paper, we introduce a post-processing method, the Multi-Head Attention Refiner (MA-R), designed to address this issue by integrating a multi-head attention mechanism into the U-Net style refiner module. Our method demonstrates improved capability in capturing intricate image details, leading to significant enhancements in boundary predictions and recall rates.

This study examined racial disparities in Head Start's impact on health outcomes for families with young children in poverty. Research questions were as follows: (a) are there racial disparities in health outcomes among low-income families? (b) Does Head Start participation promote better health outcomes? And (c) does Head Start's impact on health outcomes differ by race and ethnicity? Logistic regression analysis found that African American and Hispanic children experience lower health outcomes than their white peers, including lower rates of dental screening, more frequent injury-related care, lower overall health status, and lower rates of health insurance coverage. In comparison to White parents, African American and Hispanic parents reported lower levels of cigarette smoking.

Based on the Head Start Impact Study, 1706 parents who had mild, moderate, and severe depressive symptoms were selected to examine the following questions: (1) Are there racial disparities in mental health service utilization among low-income parents? (2) Does Head Start have an impact on mental health service utilization across white, African American, and Hispanic parents? The present research found that, compared to white parents, African American and Hispanic parents are significantly less likely to utilize mental health services. Head Start impact was found for white parents but not for African American and Hispanic parents. Furthermore, parents who spoke a language other than English had higher household risk factors, and reside in rural areas are less likely to utilize mental health services.

Crizotinib is an oral selective small-molecular tyrosine kinase inhibitor (TKI) that suppress the activity of anaplastic lymphoma kinase (ALK) and ROS1 kinases, as well as mesenchymal-epithelial transition. The cumulative clinical trials in patients with advanced ALK- or ROS1-rearrangement NSCLC indicate that crizotinib has significant antitumor activity and a tolerable safety profile, with mild or moderate adverse events of visual disorders, diarrhea, nausea, and vomiting. As with other TKIs, however, the occurrence of crizotinib-related interstitial lung disease (crizotinib-ILD) remains a major clinical dilemma that can lead to the permanent discontinuation of TKI during cancer treatment.

This study examined the effects of adverse childhood experiences (ACEs) on parental social services use among Head Start-eligible low-income families. Based on the Head Start Impact Study data (N = 3,562), three questions were addressed: (1) Does the number of ACEs impact parental social services use? (2) Do family characteristics have any association with parental social services use? and (3) Does parental social services use differ between Head Start and non-Head Start parents? Regression indicated that parents with more ACEs tended to use more social services. Compared with parents with one ACE, parents with two ACEs and parents with three or more ACEs used more social services with income assistance, food and nutrition assistance, and housing and utility assistance programs.
