Excessive Ostial Stent Protrusion: Evaluation of Management Strategies and Clinical Outcomes of the Side Flap Technique

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Backgrounds Accurate stent positioning in aorto‐ostial lesions remains challenging due to complex three‐dimensional anatomy, lack of optimal fluoroscopic projections, and high rates of geographic miss. Stent overhang impairs guide catheter re‐engagement and complicates future revascularization.

Numerical analysis of waffle slabs in flexure considering the effects of concrete cracking

Revista IBRACON de Estruturas e Materiais
Waffle slab structures simulated by computational model are generally analyzed by simplified methods, for both the section geometry (converting into solid slabs or grids) and for the material mechanical properties (linear elastic regime).

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes

Chemie Ingenieur Technik, EarlyView.
A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,

Cytomorphology and Molecular Profile of Hyalinizing Clear Cell Carcinoma of the Lung: A Case With Mucinous Differentiation

Diagnostic Cytopathology, EarlyView.
ABSTRACT Hyalinizing clear cell carcinoma (HCCC) of the lung is an exceedingly rare salivary gland‐type neoplasm with limited cytomorphologic description. We report a case highlighting these features. A 3 mm incidental left‐airway lesion enlarged to 7 mm over 5 months, prompting radial endobronchial ultrasound (EBUS)‐guided transbronchial biopsy. Touch

Seismic analysis and design of tunnels within fault ground: A review

Deep Underground Science and Engineering, EarlyView.
The research methods of seismic response of tunnels within fault ground, including field investigations, analytical solutions, physical experiments, and numerical simulations, and seismic countermeasures are discussed. The present study examines the shortcomings and limitations of the current research and design, and puts forward proposals for future ...

Seismic Assessment Procedure for Exterior Reinforced Concrete Beam–Column Joints With Slab and Transverse Beams

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This article presents a capacity‐based assessment procedure for beam–column (b–c) joints of reinforced concrete frames with floor slabs and transverse beams. The procedure extends a previously proposed assessment methodology for determining the hierarchy of strengths and the sequence of events in symmetrically reinforced planar b–c joints.

Limited Sensitivity of Ultrasound‐Guided Fine‐Needle Aspiration Cytology for Occult Nodal Metastases in Early‐Stage Oral Squamous Cell Carcinoma

Head &Neck, EarlyView.
ABSTRACT Background Ultrasound‐guided fine‐needle aspiration cytology (US‐FNAC) is commonly used in the diagnostic work‐up of head and neck cancer, but its ability to detect occult lymph node metastases in early‐stage oral squamous cell carcinoma (OSCC) with a clinically negative neck remains unclear.
