Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

Hemolytic Disease of the Fetus and Newborn: Fetal RHD Genotyping, Targeted Prophylaxis, and Prenatal Therapies

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Hemolytic disease of the fetus and newborn (HDFN) remains a significant concern in prenatal care primarily caused by maternal alloimmunization against fetal red blood cell antigens, most commonly the D antigen. Noninvasive fetal RHD genotyping, used as a screening tool, enables targeted antenatal prophylaxis and has been implemented in several

Intrauterine Transfusions in Fetuses Affected by Parvovirus B19: Complications, Challenges and Outcomes

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective This study evaluates the procedural characteristics, complications, and outcomes of intrauterine transfusion (IUT) for fetal anemia caused by parvovirus B19 infection during the 2023–2024 epidemic in Northwestern Europe. Method This multicenter observational study included all fetuses undergoing IUT for proven parvovirus B19‐induced ...

Middle Cerebral Artery Doppler and Cerebroplacental Ratio Predict Adverse Neurological Outcomes in Fetal Growth Restriction

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective To assess the efficacy of middle cerebral artery (MCA) Doppler ultrasonography in predicting neurological and respiratory outcomes in fetuses with fetal growth restriction (FGR) and to establish a correlation between MCA Doppler and head circumference (HC). Method Retrospective cohort study examining singleton pregnancies affected by

Research status of channel estimation and signal detection techniques for orthogonal time frequency space modulation

open access: yesTongxin xuebao
Orthogonal time frequency space (OTFS) modulation is a multiplexing technique designed in the two-dimensional (2D) delay-Doppler domain suited for high Doppler fading channels. OTFS converts a doubly-selective channel into an almost non-fading channel in

Structural Variation Sequencing of 26 Amniotic Fluid Samples With Partial Gene Duplications and Postnatal Follow‐Up of the Fetuses

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objectives Partial gene duplications (PGDups) are a significant contributor to genetic disease. The precise genomic location and structure of PGDups are often unresolved using conventional methods, so prenatal diagnosis for PGDups is challenging, especially without ultrasound abnormalities.

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.

Sono‐Vasomics With Super‐Resolution Contrast‐Enhanced Ultrasound (SR‐CEUS) for Characterization of Focal Liver Lesions: A Case Report

open access: yesPortal Hypertension &Cirrhosis, EarlyView.
ABSTRACT Accurate differentiation between benign and malignant focal liver lesions (FLLs) remains a major diagnostic challenge. Vasomics, an emerging discipline, classifies vascular phenotypes into anatomical, biomechanical, biochemical, pathophysiological, and composite categories. Sono‐Vasomics, the ultrasound‐based subset, leverages super‐resolution

Modulation of wind drag by tidal currents in an embayment

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Tidal currents modulate how wind energy enters the surface wave field by influencing both wave drag and wave generation. In Shark Bay, following currents reduce effective wave steepness and wind drag, and opposing currents enhance wave growth. Wind energy is partitioned between wave drag and the creation of new waves, explaining observed tidal ...
