Towards Advanced Intelligent and Perceptive Soft Grippers

Advanced Intelligent Systems, EarlyView.
Implementing soft yet strong and intelligent soft grippers request innovative and creative solutions in designing soft bodies and seamlessly integrating actuated systems with hierarchical sensing. This review systematically analyses soft grippers with a deep understanding of core components, from fundamental design principles to actuation and sensing ...

Dating the penultimate great earthquake in south-central Alaska using tree-ring crossdating and radiocarbon wiggle-matching

Quaternary Science Advances
A forest bed of tree stumps currently in the intertidal zone at Girdwood, south-central Alaska, records coseismic submergence during the penultimate great earthquake.

Short-Term Magnetic Field Variations From the Post-depositional Remanence of Lake Sediments

Frontiers in Earth Science, 2018
Paleomagnetic records obtained from lake sediments provide important constraints on geomagnetic field behavior. Secular variation recorded in sediments is used in global geomagnetic field models, particularly over longer timescales when archeomagnetic ...

Design and Characterization of a Dual‐Mode Soft Robotic Flapping Propeller With Pneumatic Stiffness Modulation

Advanced Intelligent Systems, EarlyView.
A novel soft robotic propeller overcomes traditional efficiency‐flexibility tradeoffs via a hybrid pneumatic‐cable actuation strategy. This architecture enables active stiffness modulation with dual‐mode locomotion: tunable biomimetic swimming and earthworm‐inspired wriggling for confined spaces.

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 ...

Monolithic Framework to Simulate Fluid‐Structure Interaction Problems Using Geometric Volume‐of‐Fluid Method

International Journal for Numerical Methods in Fluids, EarlyView.
A three‐dimensional fluid‐structure interaction (FSI) framework is developed using the geometric volume‐of‐fluid (VOF) interface capturing method and applied to assess largescale turbulent FSI interactions. The monolithic FSI framework is extensively validated, and despite the discontinuities across the interface, the FSI framework delivers stable and ...

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 ...

Radiocarbon Wiggle-Matching of Japanese Historical Materials with a Possible Systematic Age Offset [PDF]

Radiocarbon, 2007
Progress in radiocarbon accelerator mass spectrometry (AMS) techniques enables much more access to wiggle-matching techniques for high-precision 14C dating with relatively low costs than before. Recently, we have applied wiggle-matching for a number of wood samples where dendrochronology is difficult because of various limitations imposed for dendro ...

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 ...

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.
