Abrupt changes in alpha decay systematics as a manifestation of collective nuclear modes

, 2010
An abrupt change in $\alpha$ decay systematics around the N=126 neutron shell closure is discussed. It is explained as a sudden hindrance of the clustering of the nucleons that eventually form the $\alpha$ particle. This is because the clustering induced

A 400‐Year Sediment Record of Tsunamis in Qi'ao Island, Centered at Guangdong‐Hong Kong‐Macao Greater Bay Area

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Identifying tsunamis and determining inundation extent is critical for coastal hazard assessment. We identify potential tsunami deposits in the Guangdong‐Hong Kong‐Macao Greater Bay Area that occurred in 1555 ± 135 CE using a multidisciplinary approach.

New experimental limits on the alpha decays of lead isotopes

, 2012
For the first time a PbWO4 crystal was grown using ancient Roman lead and it was run as a cryogenic detector. Thanks to the simultaneous and independent read-out of heat and scintillation light, the detector was able to discriminate beta/gamma ...

The Holocene sedimentary record of Mittie Glacier dynamics in Smith Bay, Ellesmere Island (eastern Canadian Arctic Archipelago)

Journal of Quaternary Science, Volume 40, Issue 7, Page 1191-1211, October 2025.
ABSTRACT The physical, sedimentological, mineralogical, and elemental geochemical properties of sediment cores collected in Smith Bay (22BC and 01PC), and near the front of Mittie Glacier (23BC and 01GC), were used to reconstruct glacial sediment discharge and trace the long‐term composition and provenance of detrital sediments for the northeastern ...

Mountainous vegetation succession and land use during the last millennium in the Peloponnese (southern Greece): Environmental change and economic development in an isolated periphery

Journal of Quaternary Science, Volume 40, Issue 7, Page 1269-1284, October 2025.
ABSTRACT Mediterranean mountainous areas and their valuable natural resources have long been attractive to human societies. The Peloponnese (southern Greece), with its complex topographic and climatic variability, has been the scenery for the development of numerous human communities.

Megathrust Earthquake Legacy Linked to Changes in Widespread Potential for Methane and Iron Cycling in Glaciated Wetlands

AGU Advances, Volume 6, Issue 5, October 2025.
Abstract Freshwater wetlands are major sources of global methane emissions through biogenic methanogenesis, a process increasingly influenced by climate change. High latitude wetlands are subject to uniquely altered biogeochemical inputs due to disproportionate warming.

Radiometric dating of sediment records in European mountain lakes

Journal of Limnology, 2000
Sediment cores from seven European mountain lakes collected as part of a study of palaeolimnogical records of climate change (the MOLAR project) were dated radiometrically by 210Pb.

Dating recent sediments from the subaqueous Yangtze Delta and adjacent continental shelf, China

Journal of Palaeogeography, 2014
In this study we analyzed sediment lithology, fallout of 210Pb and 137Cs, and spheroidal carbonaceous particles (SCPs) for two short cores, YZE and CX38, obtained by gravity corer from the Yangtze River mouth offshore and adjacent continental shelf, to ...
