Two‐Stage Treatment for Adult Large Patent Ductus Venosus

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This is the first report of a two‐stage treatment for an adult large PDV involving the first stage surgical angioplasty of the large Arantius' duct and second stage embolization of the formed small Arantius' duct. The two‐stage approach could avoid embolic material migration into the systemic circulation or acute portal hypertension associated with the

Convective layered flows of a vertically whirling viscous incompressible fluid. Velocity field investigation

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019
This article discusses the solvability of an overdetermined system of heat convection equations in the Boussinesq approximation. The Oberbeck-Boussinesq system of equations, supplemented by an incompressibility equation, is overdetermined.

Turbulence modeling and surface heat transfer in a stagnation flow region [PDF]

open access: yes
Analysis for the turbulent flow field and the effect of freestream turbulence on the surface heat transfer rate of a stagnation flow is presented. The emphasis is on modeling and its augmentation of surface heat transfer rate.

Multifunctional Framework Nucleic Acid Vehicle for Antibiotic Sensitization and Treatment of Methicillin‐Resistant Staphylococcus aureus

open access: yesAggregate, EarlyView.
A self‐assembling, aggregation‐enhanced tetrahedral DNA nanostructure (tFNA), termed TACs, enables localized accumulation and sustained release of ceftriaxone while co‐delivering antisense oligonucleotides that silence mecA, reduce PBP2a expression, and restore β‐lactam susceptibility in MRSA.

Unsteady stagnation-point heat transfer during passage of a concentrated vortex [PDF]

open access: yes
The unsteady boundary layer due to a single rectilinear vortex filament approaching a 2-D stagnation point is investigated. Assuming the vortex remains far from the surface, incompressible potential flow theory is used to determine the time dependent ...

Sound‐Based Assembly of Magnetically Actuated Soft Robots Toward Enhanced Release of Extracellular Vesicles

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Magnetic soft robots offer promise in biomedicine due to their wireless actuation and rapid response, but current fabrication methods are complex and have limited cellular compatibility. A new, contactless bioassembly strategy using hydrodynamic instabilities is introduced, enabling customizable, centimeter‐scale robots.

Dual Neural Network Framework with SPICE Integration for Fast and Accurate Transistor Modeling

open access: yesAdvanced Intelligent Systems, EarlyView.
Neural network (NN)‐based compact transistor models are often deployed and evaluated standalone due to the lack of compatibility with existing simulation program with integrated circuit emphasis (SPICE) software. Herein, the proposed dual‐NN framework with the best trade‐off between high speed and high accuracy is integrated into commercial SPICE ...
