Southern Portugal hydroclimate of the last millennium from near‐annually resolved speleothem records

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Hydroclimate in Portugal is influenced by the North Atlantic subtropical high‐pressure system (the Azores High) and by internal climate modes, most prominently the North Atlantic Oscillation, which may shift in position and/or intensity due to anthropogenic climate change.

Late Quaternary lake filling and drying in northern Australia's largest freshwater lake

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Lake Woods, Jurrkulu, is northern Australia's largest freshwater lake filled today in strong Indo–Australian summer monsoons (IASM) to maximum depths of ~5 m. On the western margins of the lake, two large arcuate ridges occur 20 to 40 m above the lake floor and inset within these are other mid‐elevation lake deposits, such as depositional ...

Characterization of Dental Composite Resin with Additional TiO2 Nanoparticle Filler

open access: yesMacromolecular Symposia, EarlyView.
Silanized SiO2‐based dental composite resins with and without TiO2 nanoparticle addition were fabricated using a Bis‐GMA/TEGDMA resin matrix and photopolymerized under 468‐470 nm UV light. The resulting composites, composite I (55% SiO2) and composite II (50% SiO2 + 5% TiO2), were characterized via scanning electron microscopy (SEM), Fourier transform ...

Recovery from electrode position uncertainties in geophysical electrical resistance tomography – Application to moisture transport imaging

open access: yesNear Surface Geophysics, EarlyView.
Abstract In studies of subsurface hydrology, monitoring and imaging techniques are used to estimate the moisture content, or to track moisture or injected tracer movement. One applied imaging technique is electrical resistance tomography (ERT), in which measurements collected using electrodes placed on the ground surface or in boreholes are used to ...

FLSea: Underwater Visual–Inertial and Stereovision Forward‐Looking Data Sets

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Visibility underwater is challenging and degrades as the distance between the subject and the camera increases. That is why forward‐looking underwater computer vision tasks are difficult. We have collected underwater forward‐looking stereovision and visual–inertial image sets using two underwater imaging platforms, a stereo camera rig, and an ...
