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

Phenotypic Expansion of Knobloch Syndrome Type 2 in an Individual With a De Novo PAK2 Variant
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT P21‐activated kinase 2 (PAK2) is a serine/threonine kinase essential for a variety of cellular processes including signal transduction, cellular survival, proliferation, and migration. A recent report proposed monoallelic PAK2 variants cause Knobloch syndrome type 2 (KNO2)—a developmental disorder primarily characterized by ocular anomalies ...

Heat Transfer, Volume 52, Issue 1, Page 193-215, January 2023., 2023 Abstract A “fountain filling box” flow produced by discharging a weak laminar plane fountain in a confined open channel is studied numerically. Two‐dimensional direct numerical simulations were performed for weak plane fountains. The development of the fountain flow experiences five stages; the initial upflow and the subsequent downflow after the ...

Learning-based Trajectory Tracking for Bird-inspired Flapping-Wing Robots [PDF]
arXivBird-sized flapping-wing robots offer significant potential for agile flight in complex environments, but achieving agile and robust trajectory tracking remains a challenge due to the complex aerodynamics and highly nonlinear dynamics inherent in flapping-wing flight.

Robust Attitude Tracking for Aerobatic Helicopters: A Geometric Approach [PDF]
arXiv, 2017 This paper highlights the significance of the rotor dynamics in control design for small-scale aerobatic helicopters, and proposes two singularity free robust attitude tracking controllers based on the available states for feedback. 1. The first, employs the angular velocity and the flap angle states (a variable that is not easy to measure) and uses a ...

Infrahyoid fascio-myocutaneous flap as an alternative to free radial forearm flap in head and neck reconstruction. [PDF]
, 2007 The use of microvascular free flaps is currently the favored method for the reconstruction of defects after resection of head and neck cancer. The flap most commonly used for head and neck reconstruction is the free radial forearm flap, but the less ...

Animal Models and Experimental Medicine, EarlyView.Donor nerve selection is a crucial factor for the clinical outcomes of facial reanimation surgery. We designed an animal model to verify the feasibility and effectiveness of dual nerve neurotization approaches using cross‐facial nerve graft and the masseteric nerve in Wistar rats.

Cross-leg flap after free flap failure: a case report [PDF]
The cross-leg flap is a technique that has been used for a long time to address defects in the distal third of the leg. Currently, the gold standard for these defects is free flap reconstruction.

The SIEA SHRIMP flap: An ultrathin axial pattern free flap useable in obese patients [PDF]
, 2022 The reconstruction of distal extremity wounds poses a unique surgical challenge. In free tissue transfer, a thin, pliable skin flap is the ideal. Obese patients have a paucity of thin skin donor sites. Herein we report the discovery of a free SHRIMP flap
