Experimental Investigation of Aerodynamics of Feather-Covered Flapping Wing

Applied Bionics and Biomechanics, 2017
Avian flight has an outstanding performance than the manmade flapping wing MAVs. Considering that the feather is light and strong, a new type of the flapping wing was designed and made, whose skeleton is carbon fiber rods and covered by goose feathers as

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.

Geolocation with a magnetic sensor

Methods in Ecology and Evolution, EarlyView.
Abstract Many migratory animals use spatial variation in the Earth's magnetic field for orientation and navigation. This raises the possibility of exploiting these same cues to geolocate and track migratory animals throughout their annual journeys. Magnetic‐based geolocation could be particularly valuable for small aerial and aquatic species, for which

Short‐Term Surgical Outcomes: Modified Dorsal Inlay Graft Versus Tubularized Incised Plate Urethroplasty in Pediatric Hypospadias With Narrow Urethral Plates

Andrology, EarlyView.
ABSTRACT Background Reconstructing the urethra presents in hypospadias surgery is difficult. Occasionally, the urethral plate (UP) may be quite narrow, necessitating augmentation or replacement to achieve additional tubularization. Objective The objective of this research was to assess the application of modified dorsal inlay graft (mDIG) and ...

Prediction and Measurement of Hovering Flapping Frequency Under Simulated Low-Air-Density and Low-Gravity Conditions

Biomimetics
The ability to predict lift is crucial for enabling flapping flights on planets with varying air densities and gravities. After determining the lift required for a flapping flight on Earth, it can be predicted under different conditions using a scaling ...

Democratising Multi‐Projector Displays

Computer Graphics Forum, EarlyView.
Spatially augmented reality (SAR) transforms large, surround, collaborative experiences out of VR/AR headsets to the real world by merging content from projectors with the physical environment. This detailed state‐of‐the‐art survey reports on the advancements in multi‐projector aggregation and hardware technologies used to achieve SAR and build ...

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

Computer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

Retrospective case series of two‐stage folded paramedian forehead flap nasal reconstruction without cartilage grafts

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background Full‐thickness nasal defects of the tip, soft triangle, and ala are commonly reconstructed using a paramedian forehead flap with cartilage grafts or an epithesis. However, these approaches may be associated with donor‐site morbidity and psychological burden.
