A lock exchange experiment is used to investigate the propagation of gravity currents through a random array of rigid, emergent cylinders which represents a canopy of aquatic plants. As canopy drag increases, the propagating front varies from the classic profile of an unobstructed gravity current to a triangular profile. Unlike the unobstructed lock exchange, the gravity current in the canopy d...

Design of the DNA origami structures. Using caDNAno, we designed the following three DNA origami structures: a straight 6by-3 honeycomb-pleated structure (HC), a straight 4-by-4 squarepleated structure (SQ), and a 6-by-3 honeycomb-pleated structure having a 90◦ programmable bend (HC-90◦). Below, we briefly describe our protocols for obtaining the caDNAno designs. Building a DNA origami structur...

background: disorders of sex development (dsds) belong to uncommon pathologies and result from abnormalities during gonadal determination and differentiation. various gene mutations involved in gonadal determination and differentiation have been associated with gonadal dysgenesis. despite advances in exploration of genes and mechanisms involved in sex disorders, most children with severe 46,xy ...

A new analytical theory for multiple scattering of cylindrical acoustic waves by an array of finite impedance semi-cylinders embedded in a smooth acoustically hard surface is derived by extending previous results for plane waves [Linton and Martin, J. Acoust. Soc. Am. 117 (6) 3413 – 3423 (2005)]. Although the computational demands of the new theory increase as the number of the semi-cylinders i...

In this paper, free vibration analysis of orthotropic functionally graded material (FGM) cylinders was carried out by a Mesh-Free method. In this analysis, moving least squares shape functions are used for approximation of displacement field in the weak form of equilibrium equation. Essential boundary conditions are imposed by transformation method. In this simulation, an axisymmetric model is ...
