Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

Microbially driven organic carbon cycling at the land−sea interface: Advances and an integrated study framework

open access: yesmLife, EarlyView.
Abstract The land−sea interface is a vital component of global biogeochemical cycles, where microorganisms drive the cycling of carbon, nitrogen, and sulfur. This review synthesizes the research progress from representative land−sea interfaces to elucidate how the microbial community structure and metabolic function influence the mobilization ...

VQ‐Wave: A Physics‐Driven Spatiotemporal Deep Learning Approach for Noncontrast‐Enhanced Lung Ventilation and Perfusion MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a robust deep learning framework for noncontrast‐enhanced functional lung MRI, overcoming the limitations of spectral decomposition in the presence of physiological nonstationarity. Methods We introduce VQ‐Wave (Ventilation/Q‐perfusion Waveform‐based Assessment of Variable Evolutions), a physics‐driven spatiotemporal ...

Ventilation Imaging of the Lung at 0.55T With Continuous Slice Cycling

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To propose and evaluate a novel method for pulmonary ventilation imaging, offering considerably improved SNR. Methods A continuous slice cycling (CSC) acquisition scheme is proposed to exclusively capture signal modulations from respiratory motion with increased SNR.

Error Traps in Pediatric Neuromuscular Block

open access: yesPediatric Anesthesia, EarlyView.
ABSTRACT Background Neuromuscular blocking agents are essential for safe pediatric anesthesia but remain a frequent source of preventable morbidity when misused, inadequately monitored, or incompletely reversed. Children, particularly neonates and infants, are especially vulnerable to residual neuromuscular block due to developmental pharmacological ...

Role of Fiber Sizing in Interfacial Relaxation, Water Uptake and Fatigue Properties of Acrylic‐Matrix Composites

open access: yesPolymer Composites, EarlyView.
Characterisation of glass fibre reinforced acrylic with acrylic‐tailored or multi‐compatible sizing agents. ABSTRACT Fiber‐reinforced infusible acrylic monomer resins are of interest as recyclable alternatives to epoxy and other thermoset resin composites, but the novelty of these resins causes published studies on acrylic‐matrix composites to often ...

Respiratory profile of pediatric patients undergoing hematopoietic stem cell transplantation studied by oscillometry – A TRANSPIRE cohort

open access: yesPediatric Investigation, EarlyView.
These are results from a multi‐center collaboration between four large pediatric institutions, investigating baseline respiratory system function in a cohort of children undergoing hematopoietic stem cell transplantation. This manuscript proposes respiratory oscillometry as a novel way to prospectively follow lung function in these children.

The role of the synoptic‐scale conditions in driving fog and mist during the FATIMA July 2022 Sable Island Field program

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
ERA5 hourly 325‐m and 1512‐m (a) convergence and (b) vertical motion (actually pressure change with sign reversed to compare with convergence) over Sable Island around the time of an event. The mist (green) and fog (red) occurrences at the surface station are shown at the bottom of the figures. A 325‐m fitted line convergence was positive for the first

Determinants of Improved Dyspnea and Exercise Tolerance With Nasal High‐Flow O2 Therapy in Fibrotic Interstitial Lung Disease: A Pilot Physiological Study

open access: yesRespirology, EarlyView.
We tested the respective effect of high‐flow and supplemental O2 from nasal high‐flow O2 therapy (NHFO2) on dyspnea and exercise tolerance in fibrotic interstitial lung disease. Supplemental O2 and NHFO2 (but not high‐flow) provided improvements in these outcomes at “iso‐O2 saturation” due to reduced ventilatory requirements.

Scalable low‐cost seabed landers: the missing link for sustained, integrated, long‐term observations in dynamic shallow seas

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Seabed landers, when equipped with a range of biotic and abiotic sensors, offer a non‐invasive and cost‐effective solution for ecosystem‐scale monitoring of Essential Biodiversity Variables (EBVs) and Essential Ocean Variables (EOVs) in dynamic shallow seas.
