Occurrence Probability of Large Solar Energetic Particle Events: Assessment from Data on Cosmogenic Radionuclides in Lunar Rocks [PDF]

Solar Phys., 289, 211-220 (2014), 2013
We revisited assessments of the occurrence probability distribution of large events in solar energetic particles (SEP), based on measurements of cosmogenic radionuclides in lunar rocks. We present a combined cumulative occurrence probability distribution of SEP events based on three time scales: directly measured SEP fluences for the last 60 years ...

Superficial radiation therapy for nonmelanoma skin cancer: A review

Dermatological Reviews, Volume 3, Issue 6, Page 409-417, December 2022., 2022
Abstract Background The high prevalence of nonmelanoma skin cancer (NMSC) has become a global health‐care burden. Various modalities have been established to treat NMSC, with surgery being the mainstay approach. Superficial radiation therapy (SRT) has been in use for over a century to treat various conditions. Recent discussion among the dermatological

A perspective from extinct radionuclides on a Young Stellar Object: The Sun and its accretion disk [PDF]

Annual Review of Earth and Planetary Sciences (2011) 39: 351-386, 2011
Meteorites, which are remnants of solar system formation, provide a direct glimpse into the dynamics and evolution of a young stellar object (YSO), namely our Sun. Much of our knowledge about the astrophysical context of the birth of the Sun, the chronology of planetary growth from micrometer-sized dust to terrestrial planets, and the activity of the ...

Topographic thresholds for gully head formation in badlands

Earth Surface Processes and Landforms, Volume 47, Issue 15, Page 3558-3587, December 2022., 2022
Gully topographic threshold model was extended to badlands, on the basis of data collected in the Mediterranean environment in Italy and Spain, characterized by diversified climatic, lithological, geological and anthropogenic settings. Criteria for the attribution of curve number values has been more objectively defined in order to reduce arbitrariness

Hybrid Single-Photon Emission Computed Tomography/Computed Tomography Imaging Features of Tumoral Calcinosis in Technetium-99m Methylene Diphosphonate Bone Scintigraphy

World Journal of Nuclear Medicine, 2015
Tumoral calcinosis (TC) is an uncommon ectopic calcification syndrome. TC is a benign condition characterized by the presence of large calcific soft tissue deposits occurring predominantly in a periarticular location.

Lutetium 177 PSMA radionuclide therapy for men with prostate cancer: a review of the current literature and discussion of practical aspects of therapy

Journal of Medical Radiation Sciences, 2017
Prostate‐specific membrane antigen (PSMA) is a receptor on the surface of prostate cancer cells that is revolutionising the way we image and treat men with prostate cancer. New small molecule peptides with high‐binding affinity for the PSMA receptor have

Regionalized chemical footprint method to identify aquatic ecotoxicity hotspots of hard disk drive rare‐earth magnets

Integrated Environmental Assessment and Management, Volume 19, Issue 1, Page 272-283, January 2023., 2023
Abstract The chemical footprint (ChF), which combines life cycle assessment (LCA) and quantitative risk assessment principles, shows promise for exploring localized toxicity impacts of manufacturing processes, which is not achievable with LCA alone. An updated ChF method was applied to the global annual production of a hard disk drive (HDD) rare‐earth ...
