Although tidal marshes are known for their coastal defense function during storm surges, the impact of extreme wave forcing on marsh development is poorly understood. Seedling survival in first season after germination, which may involve exposure to events, crucial natural establishment and human restoration marshes. We hypothesize that species-specific plant traits plays a significant role see...

Hydrogels have numerous biomedical applications including synthetic matrices for cell culture and tissue engineering. Here we report the development of hydrogel based multifunctional matrices that not only provide three-dimensional structural support to the embedded cells but also can simultaneously provide potentially beneficial dynamic mechanical and electrical cues to the cells. A unique asp...

The cilia and flagella of eukaryotic cells function by active bending that produces cell movements and fluid flows in their environment. They contain a common cytoskeleton, known as the axoneme, that is the locus of all the enzymes and mechanical components that are required for production of useful bending. The bending of many flagella, and some cilia, is planar, or at least nearly planar. In ...

DNA bending plays an important role in many biological processes, but its molecular and energetic details as a function of base sequence remain to be fully understood. Using a recently developed restraint, we have studied the controlled bending of four different B-DNA oligomers using molecular dynamics simulations. Umbrella sampling with the AMBER program and the recent parmbsc0 force field yie...

Softness of human hair plays a big roll on the manageability of it. Therefore, it is important to measure the softness quantitatively. It is well known that the softness of long shaped materials can be obtained from tensile young's modulus and bending modulus. The tensile young's modulus is most generally empolyed as a parameter of softness, but is usually obtained by destructive way. Bending e...

Partial submergence induces rapid internodal elongation in deepwater rice (Oryza sativa L., cv Habiganj Aman II). We measured in vivo extensibility, tissue tension, hydraulic conductance and osmotic potential in the region of cell elongation in the uppermost internode. The in vivo extensibility of the internode, measured by stretching of living tissue with a custom-made constant stress extensio...

In the present study, a method is proposed which generates bending sequences of a sheet metal part handled by a robot. If parts are handled by a robot, the best grasping positions for each bending and the number of repositions must be indicated in advance. Using the proposed method, feasible bending sequences with grasping positions are obtained and the sequences are sorted in order of the numb...

It is shown theoretically that the lateral tension associated with bending

The DI methods for directly solving a system of a general higher order ODEs are discussed. The convergence of the constant stepsize and constant order formulation of the DI methods is proven first before the convergence for the variable order and stepsize case. 1. INTRODUCTION Many problems in engineering and science can be formulated in terms of such a system. The general system of higher orde...

Concrete-timber composite floor is a construction technique combining two materials, concrete and timber, connected together using some form of interlayer shear connectors either positioned discretely or continuously along the span of the floor. The interlayer connections provide the desired composite action, where the degree of this composite action is governed by the types of connection syste...
