Role of Fetoscopic Airway Evaluation Immediately Preceding EXIT Procedure in Fetuses With Suspected Airway Obstruction

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective This study describes the role of pre‐EXIT (Ex Utero Intrapartum Treatment) fetoscopic airway evaluation in fetuses with suspected airway obstruction. Methods Single center, retrospective, observational study including fetuses with suspected airway obstruction undergoing fetoscopic airway evaluation prior to EXIT between 2013 and 2025.

Median Effective Volume of 0.2% Ropivacaine for Ultrasound‐Guided Axillary Brachial Plexus Block in Children Aged 6–10 Years: A Prospective Dose‐Finding Study Using Up‐and‐Down Sequential Allocation

open access: yesPediatric Discovery, EarlyView.
Purpose: This study aimed to determine the median effective volume (EV50) of 0.2% ropivacaine for ultrasound‐guided axillary brachial plexus block (ABPB) in children aged 6–10 years, using the Dixon up‐and‐down method. The EV50 was 0.350 mL/kg (95% CI: 0.197–0.362 mL/kg), calculated by isotonic regression and bootstrapping.

Spatial observation‐error correlations for AMSU‐A in all‐sky assimilation: An ECMWF and UK Met Office intercomparison

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Assimilation of AMSU‐A all‐sky observations can be increased up to fivefold if spatial observation‐error correlations are accounted for properly. New correlation estimates derived using data from ECMWF and the UK Met Office reveal that correlation length‐scales are between 75 and 150 km for AMSU‐A channels peaking in the troposphere. This is attributed

Characteristics of upper‐level updrafts and downdrafts in the anvils of tropical deep convective clouds

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study investigates the thermodynamic and microphysical characteristics of updrafts and downdrafts of tropical deep convective anvil clouds using in situ measurements. We found that parts of the downdrafts are in ice supersaturation in these clouds.

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 ...

Dumpsite Seabed Characterization of the San Pedro Basin, CA, From Autonomous Vehicle Observations

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT A wide‐area seabed survey was conducted using autonomous underwater vehicles (AUVs) in a known dumpsite off the coast of Southern California that has been found to have widespread sediment contamination from the chemical dichlorodiphenyltrichloroethane (DDT).

Validation of a Particle Image Velocimetry Algorithm Through Comparative Field and Laboratory Analysis

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Flow velocity measurement is fundamental to hydrological and hydraulic studies, providing essential data for streamflow estimation and river dynamics analysis. Traditional in situ methods like propeller gauges and acoustic Doppler current profilers are accurate but intrusive and labour‐intensive, while non‐intrusive image processing methods ...

IVyTools: Space–Time Image Velocimetry for Streamflow

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Accurate streamflow measurements are essential for hydrologic monitoring, flood forecasting, and water resource management. Traditional in situ methods, although reliable, are often impractical or unsafe during flood conditions or at inaccessible locations. Image velocimetry techniques offer a potential non‐contact alternative, yet operational
