From Negative Duplex to Phlegmasia in Minutes: Bedside POCUS Identifies Rapid Thrombosis Unmasking Underlying May–Thurner Syndrome

open access: yesJournal of Clinical Ultrasound, EarlyView.
Point‐of‐care‐ultrasound revealed an evolving acute noncompressible deep vein thrombosis (asterisks) in the left lower extremity veins (right panel) that was not evident on duplex ultrasound 14 min prior (left panel; asterisks demonstrate compressed veins). The patient was treated emergently and found to have May–Thurner syndrome.

Outcomes of surgical versus conservative treatment in pediatric median arcuate ligament syndrome

open access: yesJournal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Median arcuate ligament syndrome (MALS) involves compression of the celiac artery and presents with gastrointestinal symptoms. We evaluated outcomes after surgical versus conservative management in pediatric MALS. Methods We reviewed charts of symptomatic patients aged 7–21 years diagnosed by ultrasound and/or computed tomography ...

Comparison of 3‐Dimensional Ultrasound and Computed Tomography for Imaging of Abdominal Aortic Aneurysms

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Objectives Three‐dimensional ultrasound (3D US) is emerging as a novel imaging method for abdominal aortic aneurysms (AAAs) as it creates a low‐cost 3D AAA overview without harmful radiation and nephrotoxic contrast agents, as opposed to conventional imaging. 3D US can be used with a non‐nephrotoxic contrast agent (3D‐CEUS) for lumen delineation.

Intrinsically Design‐Rule‐Compliant Nanophotonic Inverse Design via Learned Generative Manifolds

open access: yesLaser &Photonics Reviews, EarlyView.
A generative reparameterization framework for nanophotonic inverse design is introduced, restricting optimization to a learned manifold of design‐rule‐compliant geometries. Unlike conventional penalty‐based approaches, fabrication constraints are encoded intrinsically within the design representation.

Experimental and Comparative Study of the Corrosion Behavior of Lean Duplex Stainless Steel in Seawater

open access: yesMaterials and Corrosion, EarlyView.
The localized corrosion behavior of lean duplex stainless steel EN 1.4062 is systematically compared with austenitic and higher‐alloyed duplex grades in natural seawater. A clear resistance ranking is established, highlighting EN 1.4062 as a cost‐effective alternative for limited marine exposure.

Corrosion Behavior of Commercial FeCrAl and TiAl Alloys in Molten Pb With 2E‐7 wt% Oxygen at 600°C and 700°C

open access: yesMaterials and Corrosion, EarlyView.
Excellent corrosion resistance of commercial Al‐containing materials is shown for exposures to liquid lead (Pb) at 600°C. However, oxide scale failure occurs at 700°C. The formed oxide scales and their failure mechanisms are explored. ABSTRACT Liquid lead (Pb) is an attractive heat transfer fluid for advanced thermal energy storage (TES) systems.

Analysis of Corrosion and Wall Perforation in the Heat Exchanger Made of AISI 316L Stainless Steel

open access: yesMaterials and Corrosion, EarlyView.
Elevated passivation temperature is identified as the dominant factor triggering localized corrosion and subsequent perforation of AISI 316L heat exchanger tubes. Electrochemical and complementary characterization results show that the alloy retains high resistance to general, pitting, and intergranular corrosion, indicating that failure primarily ...

Hydrogen‐Enhanced Stress Corrosion Cracking of Wire Arc Additive Manufactured Inconel 625 Superalloy in NaCl Solution: Mechanism of Synergistic Degradation

open access: yesMaterials and Corrosion, EarlyView.
Hydrogen‐enhanced SCC of WAAM Inconel 625 in 3.5 wt.% NaCl solution. Hydrogen charging reduces passive film stability (lower corrosion potential) and promotes pitting at Laves phase/matrix interfaces. Stress corrosion cracks propagate along Laves‐rich regions, leading to quasi‐cleavage brittle fracture.
