Interaction of multiple vortices over a double delta wing
Interaction of strake and wing vortices over a 70◦/50◦double delta wing were studied experimentally in a wind tunnel using particle image velocimetry (PIV) measurements. The upstream effect of the wing vortex on the formation of...
Distributed Actuation and Control of a Tensegrity Based Morphing Wing
Modern aircraft wings change shape via the deflection of discrete, hinged, control surfaces, which often exhibit areas of adverse pressure gradient along the hinge line, leading to flow separation and poor wing efficiency. To...

Macroevolutionary shifts of WntA function potentiate butterfly wing-pattern diversity.
Anyi Mazo-Vargas, Carolina Concha, Luca Livraghi, Darli Massardo, Richard WR Wallbank, Linlin Zhang, Joseph D Papador, Daniel Martinez-Najera, Chris D Jiggins, Marcus R Kronforst, Casper J Breuker, Robert D Reed, Nipam H Patel, W Owen McMillan, Arnaud Martin
Jan 17, 2018
Butterfly wing patterns provide a rich comparative framework to study how morphological complexity develops and evolves. Here we used CRISPR/Cas9 somatic mutagenesis to test a patterning role for WntA, a signaling ligand gene...
Structure of the Chicken Neuron-Glia Cell Adhesion Molecule, Ng-CAM: Origin of the Polypeptides and Relation to the Ig Superfamily
Mark P Burgoon
Jan 01, 0001
The neuron-glia cell adhesion molecule, Ng-CAM, is a cell-surface glycoprotein expressed on neurons and Schwann cells in the chicken nervous system. It is expressed as a group of related components of -200 kD, 135 kD, and 80 kD...

Mar 21, 2022
Mode-localized sensors have attracted attention because of their high parametric sensitivity and first-order common-mode rejection to temperature drift. The high-fidelity detection of resonator amplitude is critical to...
Notch inhibits Yorkie activity in Drosophila wing discs.
During development, tissues and organs must coordinate growth and patterning so they reach the right size and shape. During larval stages, a dramatic increase in size and cell number of Drosophila wing imaginal discs is...
Wing Musculature Reconstruction in Extinct Flightless Auks (<i>Pinguinus</i> and <i>Mancalla</i>) Reveals Incomplete Convergence with Penguins (Spheniscidae) Due to Differing Ancestral States.
Despite longstanding interest in convergent evolution, factors that result in deviations from fully convergent phenotypes remain poorly understood. In birds, the evolution of flightless wing-propelled diving has emerged as a...
Aerodynamics of a wing in turbulent bluff body wakes
The aerodynamics of a stationary wing in a turbulent wake are investigated. Force and velocity measurements are used to describe the unsteady flow. Various wakes are studied with different dominant frequencies and length...
