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 ...

Investigating the toll of childhood socioeconomic disadvantage on adolescent mental health in three UK cohorts

JCPP Advances, EarlyView.
Abstract Background Low socioeconomic position (SEP) in childhood is robustly associated with adolescent mental health difficulties, yet this relationship is changing over time due to contextual and conceptual differences in these constructs. Consistent SEP and mental health data from different cohorts are required to understand changes over time ...

Tree-Ring Chronological Investigation on the Oak Poles of the Prehistoric Settlement of “Gran Carro” in Lake Bolsena, Central Italy: Landscape and Human Occupation

Land
Dendrochronological analysis was carried out at the archaeological settlement of Gran Carro, located in Lake Bolsena (Italy). According to the most recent archaeological evidence, the site dates back to the period spanning from the Middle Bronze Age ...

Differences in associations between attention‐deficit hyperactivity disorder symptoms and physical activity across childhood and adolescence and among males and females in a representative UK birth cohort

JCPP Advances, EarlyView.
Abstract Background Children and adolescents with attention‐deficit hyperactivity disorder (ADHD) exhibit higher physical activity (PA) levels than peers without ADHD. It remains unclear how this association evolves across developmental stages and differs between sexes.

¹⁴C wiggle-matching of short tree-ring sequences from post-medieval buildings in England [PDF]

, 2019
This study tests whether accurate dating by AMS radiocarbon wiggle-matching short tree-ring series (c. 30 annual rings) in the period after AD 1510 can be achieved routinely.

Not All Missing Data are Equal: Choosing the Right Imputation Method for Binary Datasets

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Missing binary predictors are common in reliability, quality control, and industrial decision systems, yet imputation methods are often chosen by convenience rather than evidence. We conduct a Monte Carlo study comparing mode substitution, sequential hot‐deck, missForest, MICE, and KNN with three neighbourhood sizes under MCAR, MAR, and MNAR ...

Application Of ¹⁴C Wiggle-Matching To Support Dendrochronological Analysis In Japan

, 2007
¹⁴C wiggle-matching was applied to two wood samples closely related to geological and archaeological events with associated dendrochronological dates, to demonstrate the accuracy of ¹⁴C dating with accelerator mass spectrometry (AMS).

Intergenerational Altruism and Sustainable Development: The Role of Descendants and Age Effects in Promoting Future Well‐Being

Sustainable Development, EarlyView.
ABSTRACT Sustainability challenges can be framed as problems of intergenerational altruism—how the current generation allocates resources to future generations. Institutional reforms such as Demeny voting assume that descendants act as intermediaries who enhance altruism toward the future. We test this “altruism premium” and evaluate two interventions,

Radiocarbon Calibration for Japanese Wood Samples [PDF]

, 2003
The radiocarbon content of Japanese cedars was measured by accelerator mass spectrometry for decadal tree-ring samples from the period of 240 BC to AD 900. Conventional gas counting was also used for part of the samples.

Three‐Dimensional Optical and Computational Reconstruction of Colloidal Electrokinetic Flows via Multiplane Imaging and Multiscale Modeling

Small, EarlyView.
Fast 3D multiplane microscopy is combined with multiscale electrokinetic modeling to reconstruct nanoparticle motion around quadrupolar electrodes. This integrated optical‐computational framework reveals the full three‐dimensional structure of colloidal electrokinetic flows, including localized trapping, depletion layers, and complex vortical motion ...
