Effect of simulated forward airspeed on small-scale-model externally blown flap noise [PDF]

open access: yes
Noise tests were conducted on a small-scale model of an externally blown flap lift augmentation system. The nozzle/wing model was subjected to external flow that simulated takeoff and landing flight velocities by placing it in a 33-centimeter-diameter ...

Total posterior leg open wound management with free anterolateral thigh flap: case and literature review. [PDF]

open access: yes, 2013
Soft tissue coverage of the exposed Achilles tendon is a unique reconstructive challenge. In this report, we describe the management of a large posterior leg wound with exposed Achilles tendon using a free anterolateral thigh (ALT) flap. A careful review

Interface Wettability Transition‐Driven Drug Release and Dual‐Phase Functionalization in Implant Abutment

open access: yesAdvanced Science, EarlyView.
A temporally controlled drug release coating is developed for abutments using a superhydrophobic coating self‐assembled on mesoporous silica. This surface provides sequential functionality: initial contamination resistance through non‐wetting, followed by controlled drug release via wettability transition.

Deltopectoral and Pectoralis Musculocutaneous Flap Technique for Cervical Esophageal Reconstruction after Free-Jejunal-Flap Necrosis

open access: yesPlastic and Reconstructive Surgery, Global Open, 2017
Background:. Free jejunal transfer has a high success rate, but if vascular thrombosis occurs, the salvage of failing flap with reanastomosis is difficult.

Wind-tunnel free-flight investigation of a 0.15-scale model of the F-106B airplane with vortex flaps [PDF]

open access: yes
An investigation to determine the effects of vortex flaps on the flight dynamic characteristics of the F-106B in the area of low-speed, high-angle-of-attack flight was undertaken on a 0.15-scale model of the airplane in the Langley 30- by 60-Foot Tunnel.

An experimental study of interceptors for drag reduction on high-performance sailing yachts [PDF]

open access: yes, 2011
Interceptors have been widely used in recent years in fast ferries and small high-speed leisure and commercial craft for ride and trim control, and steering.

A Worm‐Inspired Origami Robot with Multimodal Locomotion for Adaptive Mobility in Complex Pipeline Environments

open access: yesAdvanced Science, EarlyView.
An origami worm‐inspired robot achieves multimodal locomotion in confined pipelines through mechatronic integration that embeds actuation, control, and communication within each origami module. Large, reversible configuration and dimensional changes enable 25 gaits synthesized by a unified framework across peristaltic, inchworm, and wheel‐rolling modes

Therapeutic hand-exercising device with cycling pressure value [PDF]

open access: yes, 1974
Device exercises hands of persons whose fingers are generally straight and need to be flexed inward toward palms of hands. Device is extremely simple in design, which reduces costs, and fits all hand sizes.

A Model of Free Tissue Transfer: The Rat Epigastric Free Flap [PDF]

open access: yes, 2017
Free tissue transfer has been increasingly used in clinical practice since the 1970s, allowing reconstruction of complex and otherwise untreatable defects resulting from tumor extirpation, trauma, infections, malformations or burns.

Transposase‐Assisted Donor Tethering Boosts Large‐Fragment HDR in Plants

open access: yesAdvanced Science, EarlyView.
A transposase‐assisted donor tethering strategy is developed to enhance homology‐directed repair in plants. By recruiting donor DNA to double‐strand breaks and synergizing with repair pathway reprogramming and transcription‐coupled donor design, this system markedly improves large‐fragment targeted insertion efficiency, providing a robust platform for ...
