Thermally Drawn Bioelectric Catheters: Enabling Proprioceptive Endovascular Navigation

Advanced Intelligent Systems, EarlyView.
This work introduces a novel bioelectric navigation system eliminates the need for harmful fluoroscopy during endovascular surgeries. A bespoke 16‐electrode catheter is fabricated using rapid thermal drawing and laser micro‐machining. Paired with a real‐time tracking algorithm fusing vascular geometry detection and distance estimation, this technology ...

Cavity Flow Instabilities in a Purged High-Pressure Turbine Stage

International Journal of Turbomachinery, Propulsion and Power
As designers push engine efficiency closer to thermodynamic limits, the analysis of flow instabilities developed in a high-pressure turbine (HPT) is crucial to minimizing aerodynamic losses and optimizing secondary air systems.

Outcomes of Capsular Plication as Part of Hip Arthroscopic Management for Surgically Identified Microinstability Are Comparable to Outcomes in Matched Controls

Arthroscopy, EarlyView.
Purpose To compare 2‐year minimum outcomes of hip arthroscopic management with capsular plication in patients with microinstability with propensity‐matched controls. Methods We searched primary hip arthroscopies undertaken between August 2009 and December 2020 from a single‐surgeon database, excluding those with lateral center‐edge angle <18°, for ...

Investigation of Systematic Discrepancies Between MCC and TGA Measurements Affecting the Determination of Heat of Combustion

Fire and Materials, EarlyView.
ABSTRACT The determination of step‐resolved effective heats of combustion is essential for detailed pyrolysis modelling in fire growth and flame spread predictions, especially in multi‐step processes where the heat of combustion can differ between reaction steps.

Engineering Photonic Pigments From Titania–Block Copolymer Composites

Macromolecular Rapid Communications, EarlyView.
Ligand‐functionalized TiO2 nanoparticles selectively partition into P2VP‐rich lamellae of onion‐like PS‐b‐P2VP microspheres, increasing refractive index contrast while preserving concentric order through controlled self‐assembly. The resulting dry photonic pigments display defined Bragg reflections and angle‐robust structural color.

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

Cladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

Not all rhodoliths need a bed–depositional mechanisms in shallow water Sporolithon nodosum rhodoliths from the Whangaparaoa peninsula (North Island, New Zealand)

Sedimentology, EarlyView.
ABSTRACT Rhodoliths, formed by crustose coralline algae (CCA), are prominent components in carbonate platform deposits, contributing to the characteristic rhodalgal facies. Their formation is influenced by both biological and physical factors, and under specific conditions, they can accumulate, forming extensive rhodolith beds.
