Pre‐Curved Everting Robots With Embedded Steering Intelligence Fabricated by CO2 Laser Welding

Advanced Intelligent Systems, EarlyView.
Design and experimental demonstration of a laser welded growing robot for anatomically guided navigation. The robot follows an aortic arch phantom entering the branchiocephalic branch through steering by design. The figure shows the physical phantom setup, CAD defined weld geometry and full robot eversion.

Impinging Jet Dynamics

, 2012
In this fluid dynamics video, Ray-tracing data visualization technique was used to obtain realistic and detailed flow motions during impinging of two liquid jets. Different patterns of sheet and rim configurations were presented to shed light into the underlying physics, including liquid chain, closed rim, open rim, unstable rim and flapping sheet.

Excellent Outcomes and High Rates of Return to Duty but a 10% Chance of Tear Progression Are Seen Following Arthroscopic Debridement Alongside Adjunctive Procedures for Articular‐Sided, Partial‐Thickness Supraspinatus Tears (Ellman Grade I) in Active‐Duty Service Members Younger Than 50 Years

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To evaluate clinical outcomes and return‐to‐duty rates in active‐duty service members younger than 50 years after arthroscopic debridement of Ellman grade I, articular‐sided partial‐thickness rotator cuff tears (PT‐RCTs) of the supraspinatus.

Experimental Investigation on Acoustic Wave Generation due to Supersonic Hot Jet Impingement on an Inclined Flat Plate

Journal of Applied Fluid Mechanics, 2019
In the present paper, noise generation due to supersonic hot jet impingement (M=1.4 and Tt=950 K) to an inclined flat plate is experimentally investigated. In general, four types of acoustic waves are defined for jet impingement: acoustic waves generated

Cooling of rocket plume using aqueous jets during launching

Engineering Applications of Computational Fluid Mechanics, 2022
With an increase in rocket motor thrust, the thermal loads on the launch platform by the impingement exhaust jet are significantly increased, this poses serious safety risks to rocket launch.

Ulnar Collateral Ligament Reconstruction Through a Mini‐Invasive Approach and Suture Anchor Fixation

Arthroscopy Techniques, EarlyView.
Abstract Valgus stability of the elbow joint is mostly provided by the ulnar collateral ligament (UCL), which is composed of 3 bundles: anterior, posterior, and transverse. Many surgical techniques for UCL reconstruction have been described since Dr.

Dynamics of round jet impingement [PDF]

, 2019
The impingement of a round jet issued from a convergent nozzle is known to produce intense tonal noise. These tones are generated by a feedback process involving a Kelvin-Helmholtz instability wave and an upstream-travelling guided jet mode.

Viscosity of concentrated mRNA solutions: Implications for downstream processing

Biotechnology Progress, EarlyView.
Abstract Messenger RNA (mRNA) therapeutics can be used to protect against infectious disease and for the treatment of cancers and genetic disorders. In order to obtain the desired therapeutic dosage, it is necessary to concentrate the mRNA to levels where the viscosity of the mRNA solutions can become significant.
