Numerical Insights Into the Resistance Reduction Mechanisms of Forward Tapered Transoms in High‐Speed Catamaran: A Computational Fluid Dynamics‐Based Study

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study investigates the hydrodynamic influence of forward transom tapering on a displacement catamaran hull using computational fluid dynamics (CFD) simulations. Five taper configurations ranging from a vertical transom base design to a fully tapered stern (1.00B) were evaluated over a wide Froude number range (Fr = .3 to 1.0).

An Improved Air Film Model for Studying the Tilt Characteristics of Aerostatic Thrust Bearings

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this study, an improved mass‐spring model that treats the lubricating air film as distributed springs is proposed to calculate the static and dynamic angular stiffness of aerostatic thrust bearings. The proposed model refines the traditional mass‐spring model by introducing the spatially varying mechanical properties of the air film and the

Thermo‐Hydrodynamic Processes of Microparticles in Fractures: A CFD–DEM Approach

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Controlling fracture permeability plays a critical role in subsurface energy applications, particularly in geothermal energy production and enhanced carbon sequestration, where regulating fluid flow is essential. The use of microcapsules has become a promising solution to enhance fracture permeability by providing a controlled sealing ...

Does Total Inferior and Middle Turbinectomy Always Lead to Empty Nose Syndrome?

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Empty Nose Syndrome (ENS) is a rare and paradoxical complication often associated with aggressive turbinate reductions. Previous computational fluid dynamic (CFD) modeling has indicated that distorted nasal airflow patterns could contribute to ENS.

Unraveling the spatial landscape of dystrophinopathies: a transcriptomic approach to Becker and Duchenne muscular dystrophies

The Journal of Pathology, EarlyView.
Abstract Dystrophinopathies are caused by pathogenic variants in the DMD gene, resulting in partial (Becker) or complete loss (Duchenne) of dystrophin. Becker (BMD) and Duchenne muscular dystrophy (DMD) are characterized by progressive muscle wasting, fatty replacement, fibrosis, and loss of function.

Optimization of Microfluidic Geometry for Extracellular Vesicle Capture Using an Automated Parallel Pattern Search

PROTEOMICS, EarlyView.
ABSTRACT Microfluidic affinity‐based capture of extracellular vesicles (EVs) holds great promise for disease diagnostics and monitoring therapeutic EV production. However, optimizing microfluidic channel geometries for efficient EV capture remains understudied due to the effort required to experimentally test numerous designs.

Chinese Registry on Transjugular Intrahepatic Portosystemic Shunts (CN‐TIPS): Protocol for a Registry‐Based, Prospective Prognostic Study

Portal Hypertension &Cirrhosis, EarlyView.
CN‐TIPS is a nationwide, multicenter prospective registry that will enroll 10,000 adults with portal hypertension undergoing transjugular intrahepatic portosystemic shunt in China, integrating perioperative clinical and hemodynamic metrics with standardized imaging (including computational modeling in a dedicated subcohort) and multi‐omics biospecimens,
