Article Synopsis
- Wide-Field Small Aperture Telescopes (WFSAT) enhance observation efficiency in space surveillance but are vulnerable to external stray light, negatively affecting data quality and object positioning.
- The Pyramid Deformable Large Kernel Attention (PD-LKA) Model is introduced to combat stray light, using a pyramid structure to capture multi-scale features and improve robustness against interference.
- Testing shows the model significantly enhances image quality, achieving high PSNR and SSIM scores, and maintains positioning accuracy within 5 arcseconds for astronomical objects despite stray light challenges.
Article Synopsis
- The study aimed to assess the effectiveness of measuring PCT, CRP, and FIB levels in distinguishing between severe bacterial and viral pneumonia.
- A cohort of 100 patients with severe pneumonia, consisting of equal groups for viral and bacterial infections, was analyzed alongside a healthy control group, focusing on the differences in biomarker levels.
- Results showed that combined detection of PCT, CRP, and FIB provided higher sensitivity and specificity for diagnosing bacterial versus viral pneumonia compared to single tests, indicating its potential for better clinical diagnosis.
