3D-localization of gamma sources has the potential to improve the outcome of radio-guided surgery. The goal of this paper is to analyze the localization accuracy for point-like sources with a single coded aperture camera.We both simulated and measured a point-like241Am source at 17 positions distributed within the field of view of an experimental gamma camera.

- Hepatocellular carcinoma (HCC) is a major health risk globally, and this study aims to create a scoring system to better predict the survival rates of affected patients.
- Researchers used data from 45,827 HCC patients to identify and analyze prognostic factors, ultimately developing a model that includes 11 key clinical and demographic features.
- The new model proved to be more accurate than the existing AJCC staging system, showing strong predictive capability and alignment with real-world patient outcomes.
Estuaries, vital coastal ecosystems, face growing threats from industrialization. To understand the pace of sedimentary changes and heavy metal pollution at the anthropogenically altered and industrialized Nakdong River Estuary in South Korea, we used sediment coring to reconstruct environmental change. Estuarine dam construction in 1934 shifted the sedimentary system from sand to mud, coinciding with a post-1930s mercury increase due to coal burning.
