Artificial Neural Network Optimization to Estimate Radon in Soil

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 18, Issue 5, October 2025.
ABSTRACT Modeling and estimating radon concentration are of crucial interest to support health protection campaigns. In the literature, many studies concentrated on indoor radon, while few of them investigated the outdoor radon spatial distribution and the factors that influence its formation.

Sassolite Precipitation at the Restless Campi Flegrei Volcano in Italy Points to Hydrothermal Flashing by Deep Boron‐Rich Brines

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Studying the behavior of dormant volcanoes is a major challenge in volcanology. Here, we conducted a 10‐year survey of hydrothermal mineralization at Campi Flegrei, an active volcano near Naples in Italy, which last erupted in 1538. Our survey revealed a significant output of boric acid at the hydrothermal sulfate discharge area of Pisciarelli,

RADON EXHALATION FROM BUILDING MATERIALS USED IN YEMEN

Radiation Protection Dosimetry, 2018
The present article seeks to determine the annual effective doses of 222Rn exposure, effective radium content and radon exhalation rates in some building materials from the local market of Ibb province, Yemen. A total of 33 samples of building materials were collected from the target area. The radon exhalation rate and effective radium content in these

Non‐Invasive Diagnosis of Hypertrophic Cardiomyopathy by Breath

Advanced Sensor Research, Volume 4, Issue 7, July 2025.
The use of sensor technologies for the diagnosis of hypertrophic cardiomyopathy (HCM) by identification of volatile organic compounds (VOCs) in breath samples. By combining gas chromatography‐mass spectrometry (GC‐MS) and electronic nose (eNose) platforms, specific VOC patterns associated with HCM are detected and analyzed.
