High-precision radiocarbon dating of the construction phase of Oakbank Crannog, Loch Tay, Perthshire [PDF]
, 2010 Many of the Loch Tay crannogs were built in the Early Iron Age and so calibration of the radiocarbon ages produces very broad calendar age ranges due to the well-documented Hallstatt plateau in the calibration curve. However, the large oak timbers that

Long path and cycle decompositions of even hypercubes [PDF]
, 2021 We consider edge decompositions of the $n$-dimensional hypercube $Q_n$ into isomorphic copies of a given graph $H$. While a number of results are known about decomposing $Q_n$ into graphs from various classes, the simplest cases of paths and cycles of a ...

Phase matching strategy for the undulator system in the European X-ray Free Electron Laser
Physical Review Accelerators and Beams, 2017 The undulator system in the European X-ray Free Electron Laser is mainly comprised of 5-m long undulator segments and 1.1 m long intersections in between. The longitudinal component of the electrons’ velocity is reduced when traveling inside an undulator

Chronology and development of the Chalcolithic necropolis of Varna I
Documenta Praehistorica, 2017 In the following paper, we present the main results of our now completed studies of the Varna I cemetery, based on the excavations undertaken by Ivan Ivanov in the years 1972–1991. The richness of the assemblages is singular in Old World prehistory.

Paleomagnetic constraint of the age and duration of the Taupō Eruption, New Zealand
Earth, Planets and Space, 2023 We have carried out paleomagnetic analyses of tephras from the Taupō eruption, one of the most violent eruptions on Earth in the past 5000 years. Pyroclastic deposits were collected with 7 cm3 cubes pushed into each unit of the Taupō eruption sequence ...

Wiggle-Match Dating of Wooden Samples from Iron Age Sites in Northern Italy [PDF]
Radiocarbon, 2010 Archaeological excavations carried out at the sites of Laion/Lajen (Bolzano/Bozen) and Stufles-Oberegger (Bressanone/Brixen) in northern Italy uncovered well-preserved wooden samples in cultural layers archaeologically dated to the Iron Age. From the 2 sites, different wooden samples were recovered that were well preserved enough to allow clear ...

Bayesian 14C-rationality, Heisenberg Uncertainty, and Fourier Transform
Documenta Praehistorica, 2020 Following some 30 years of radiocarbon research during which the mathematical principles of 14C-calibration have been on loan to Bayesian statistics, here they are returned to quantum physics.
