From Isolated to Complex: Diagnostic Yield of Chromosomal Microarray and Exome Sequencing in Fetal Growth Restriction

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective To characterize the overall diagnostic yield of sequential chromosomal microarray (CMA) and exome sequencing (ES) across the phenotypic spectrum of fetal growth restriction (FGR). Methods A retrospective cohort of 320 consecutive FGR pregnancies presenting at ≥ 20 weeks to a tertiary fetal medicine unit (2020–2025).

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

Graph-enhanced neural operator for missing velocities reconstruction in river surface velocimetry

open access: yesMachine Learning. Earth
Measuring river surface velocity is essential for estimating river discharge. While traditional image-based velocimetry methods are often effective, they struggle to produce complete velocity fields under complex environmental conditions. Factors such as

Dual‐Component Spidroin‐Based Hydrogels: A Mechanically Tunable Platform for 2D and 3D Cell Culture

open access: yesSmall, EarlyView.
A dual‐component recombinant spider silk hydrogel platform was developed by combining NT2RepCT with a bioactive vitronectin‐functionalized spidroin domain. The hydrogels self‐assemble under physiological conditions, exhibit tunable mechanical properties, and support 2D and 3D cell culture, providing a versatile platform for mechanobiological studies ...

Application of digital particle image velocimetry to insect aerodynamics: measurement of the leading-edge vortex and near wake of a Hawkmoth [PDF]

open access: yes, 2007
Some insects use leading-edge vortices to generate high lift forces, as has been inferred from qualitative smoke visualisations of the flow around their wings.

Real-Time Measurement of Flash-Flood in a Wadi Area by LSPIV and STIV

open access: yesHydrology, 2019
Flash floods in wadi systems discharge large volumes of water to either the sea or the desert areas after high-intensity rainfall events. Recently, wadi flash floods have frequently occurred in arid regions and caused damage to roads, houses, and ...

Large‐Scale Applications of Plasma Technologies: Progresses and Challenges

open access: yesHigh Voltage, EarlyView.
ABSTRACT Plasma technologies convert electrical power into energetic electrons, ions, reactive species, radiation and heat, thereby breaking through the bottleneck of purely thermal or chemical routes and bringing impressive changes to our world. This roadmap reviews the progress and challenges of plasma technologies from a large‐scale and application ...

Single camera three component planar velocity measurements using two-frequency planar Doppler velocimetry (2ν-PDV) (2012) [PDF]

open access: yes, 2006
Two-frequency planar Doppler velocimetry (2ν-PDV) is used in conjunction with imaging fibre bundles to make time-averaged three component velocity measurements using a single CCD camera and iodine cell. In this scheme the flow is sequentially illuminated

X-Ray imaging method for in-situ study of particle-laden flows

open access: yese-Journal of Nondestructive Testing
 The accurate measurement of flow parameters often depends on sensor accessibility. Optical flow assessment techniques, such as Particle Image Velocimetry (PIV) and Particle Tracking Velocimetry (PTV), are limited to optically transparent media. However,
