The effect of passive deformation of dragonfly wing on aerodynamic characteristics

Nihon Kikai Gakkai ronbunshu, 2016
Dragonflies can perform both of gliding and flapping flight and have high maneuverability in spite of small-size. The aim of this study is to develop Micro Air Vehicle (MAV) based on the flight of dragonfly.

Scaling of soaring seabirds and its implication for the maximum size of flying pterosaurs [PDF]

, 2008
The flight ability of animals is restricted by the scaling effects imposed by physical and physiological factors. In comparisons of the power available from muscle and the mechanical power required to fly, theoretical studies have predicted that the ...

Supersonic transporter (SST) deformity of penile prosthesis: Current management strategies

UroPrecision, EarlyView.
Abstract Supersonic transporter (SST) deformity, also known as floppy glans syndrome, represents a persistent source of post‐operative dissatisfaction among patients undergoing inflatable penile prosthesis (IPP) implantation. Although infection and mechanical failure rates have declined with advances in device design and surgical technique, SST ...

Use of active control systems to improve bending and rotor flapping response of a tilt rotor VTOL airplane [PDF]

The results are summarized of an analytical study of the use of active control systems for the purpose of reducing the root mean square response of wing vertical bending and rotor flapping to atmospheric turbulence for a tilt-rotor VTOL airplane.

Probability forecasts – Part 1: ensembles and probabilistic forecasts

Weather, EarlyView.
Ensemble weather forecasts have been in use for many years to help forecasters understand uncertainty in weather predictions but are now becoming core to some operational Numerical Weather Prediction (NWP) systems. Ensembles offer greater predictive skill and information content than deterministic forecasts but are more complex to interpret and ...

The Mechanism of NLRP3 Inflammasome Activation and Its Roles in Chronic Rhinosinusitis

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT NLRP3 (NLR family pyrin domain containing 3) is one of the crucial receptors in pathogen recognition receptor (PRR) families which can recognize the pathogen‐associated molecular patterns (PAMPs) and the damage‐associated molecular patterns (DAMPs), thus triggering innate immune response. After NLRP3 activation, it recruits the adaptor protein

Effects of shapes and kinematics of hovering flapping wings on aerodynamic forces and vortex structures

Scientific Reports
The present study investigated the effects of wing shapes and flapping motions on the aerodynamic forces and vortex structures of insect flight. Aerodynamic force measurements and flow visualizations were performed in a water tank by cross-applying the ...

Saving Bambi from the mower? Using a drone with thermal camera to evaluate a low‐tech scaring technique to reduce roe deer fawn mortality during grass harvest

Wildlife Biology, EarlyView.
Roe deer is a species that hides their neonates as an anti‐predator strategy. This may prove efficient against mammalian predators, such as the red fox; however, it might be an ecological trap as large numbers of fawns are killed by tractors with harvesters each year during grass harvest.

Potential Correlation Between Bombus lantschouensis Thoracic Morphology and Flight Behavior

Integrative Zoology, EarlyView.
Potential correlation between Bombus lantschouensis thoracic morphology and flight behavior. ABSTRACT Remarkably little modern work has investigated the thoracic structures of insects and their relationship to flight locomotion. Most studies focus exclusively on either morphology or flight kinematics.
