In the process of mineral resource extraction, monitoring surface deformation is crucial for ensuring the safety of engineering and ground infrastructure. Monitoring complete three-dimensional surface deformation is particularly significant. Traditional synthetic aperture radar (InSAR) technology provides deformation components only along the line of sight (LOS) and often lacks sufficient effective data in vegetation-covered mining areas and mining subsidence centers.

Optical Coherence Tomography (OCT) offers high-resolution images of the eye's fundus. This enables thorough analysis of retinal health by doctors, providing a solid basis for diagnosis and treatment. With the development of deep learning, deep learning-based methods are becoming more popular for fundus OCT image segmentation.

Article Synopsis
- Fast radio bursts (FRBs) are brief bursts of radio waves from distant galaxies, and their emission mechanisms are still debated, focusing on processes near a central engine versus shocks at large distances.
- Researchers measured two scintillation scales for FRB 20221022A, one linked to the Milky Way and the other to its host galaxy, which allowed them to determine the FRB's emission region size to be less than 3 x 10 kilometers.
- This size contradicts the large-distance model and suggests that the emission likely occurs close to a central compact object, supported by an observed S-shaped polarization angle, indicating a magnetospheric emission process.
Ozone concentration, physical activity, and emotional and behavioral problems in children and adolescents.

School of Public Health, Sun Yat-sen University, Guangzhou, Guangdong, China. Electronic address:
Background: No prior study has examined the mutual association of long-term outdoor ozone (O) concentration and physical activity (PA) with emotional and behavioral problems (EBPs) in children and adolescents. This study aims to investigate the association between long-term outdoor O concentration and the risk of EBPs in children and adolescents and further explore whether increased PA levels modify this association.
Methods: Data were obtained from the 2020 wave follow-up examination of an ongoing prospective cohort study (COHERENCE project) in Guangzhou, China.
The congruence and interrelationships of family resilience in couples coping with colorectal cancer: A cross-sectional study from a dyadic perspective.

Wuxi School of Medicine, Jiangnan University, Wuxi, Jiangsu Province, China; Affiliated Hospital of Jiangnan University, Wuxi, Jiangsu Province, China. Electronic address:
Purpose: To assess the congruence and interdependent impacts of family resilience in colorectal cancer couples using the Walsh Family Resilience Model, focusing on coping domains of the shared beliefs system, organizational patterns, and communication/problem-solving.
Methods: 220 colorectal cancer couples were recruited from two hospitals in China, assessing family resilience, hope, family sense of coherence, spiritual well-being, social support, and couple communication quality. Congruence was assessed using intraclass correlation coefficients and paired t-tests.
