Near constancy of the Pacific Ocean surface to mid-depth radiocarbon-age difference over the last 20 kyr
Aftershock Sequence of the Mw 7.9 Denali Fault, Alaska, Earthquake of 3 November 2002 from Regional Seismic Network Data
The largest inland earthquake in North America in almost 150 years struck Alaska on 3 November 2002. It ruptured three different faults, with a total rupture length of ∼330 km. It started on the…
AMS Radiocarbon Measurements on Foraminifera Shells from Deep-Sea Cores
Radiocarbon ages determined by the AMS method on hand-picked foraminifera shells are reported. The results allow estimates of the ventilation rate of the deep Atlantic and Pacific Oceans during…
All That’s ‘Human’ Is Not Gold: Evaluating Human Evaluation of Generated Text
- Elizabeth Clark, Tal August, Sofia Serrano, Nikita Haduong, Suchin Gururangan, Noah A. Smith
- 30 June 2021
The role untrained human evaluations play in NLG evaluation is examined and three approaches for quickly training evaluators to better identify GPT3-authored text are explored and it is found that while evaluation accuracy improved up to 55%, it did not significantly improve across the three domains.
Evidence for the insignificance of ordinary chondritic material in the asteroid belt
Abstract— We review the meteoritical and astronomical literature to answer the question: What is the evidence for the importance of ordinary chondritic material to the composition of the asteroid…
Dynamic matching of forager size to resources in the continuously polymorphic leaf‐cutter ant, Atta colombica (Hymenoptera, Formicidae)
- Elizabeth Clark
- 1 December 2006
Examination of the colony‐level pattern of forager size allocation to resource sites in a natural setting finds that social insect colonies may increase their dietary breadth by increasing variation in worker morphology.
Dynamic cell culture for vascularized bone engineering
The role of tryptophan residues in an integral membrane protein: diacylglycerol kinase.
Fluent emission spectra for the Trp mutants do not change significantly with changing fatty acyl chain length from C14 to C24, showing efficient hydrophobic matching between DGK and the surrounding lipid bilayer, and it is suggested that Trp-25 plays a role in maintaining the alignment of ATP and DHG at the active site.
Nebuhaler versus wet aerosol for domiciliary bronchodilator therapy: A multi‐centre clinical comparison
To compare the clinical effectiveness and patient acceptance of a large spacer device (Nebuhaler™) for delivery of metered dose aerosol (MDI) terbutaline with nebulised wet aerosol terbutaline.
A dramatic Atlantic dissolution event at the onset of the last glaciation
Measurements of the CaCO3 content of the CaCO3 size index and of foraminifera weights demonstrate that a prominent dissolution event occurred in the western equatorial Atlantic at the onset of the…
