Fish larvae, like most adult fish, undulate their bodies to propel themselves. A detailed kinematic study of the larval body wave is a prerequisite to formulate a set of functional requirements that the locomotor system must fulfil to generate the observed swimming kinematics. Lateral displacement and curvature profiles were obtained for zebrafish (Danio rerio) larvae at 2-21 days post-fertilis...

Three-dimensional simulations of oscillatory convection in binary mixtures driven by the Marangoni effect have been performed. The upper surface of the fluid is heated by a constant heat flux while the bottom is maintained at a constant temperature. Surface deflection is ignored. Oscillations are the result of concentration-induced changes in the surface tension due to the presence of an anomal...

A compact standing-wave linac has been designed using S-band microwaves for medical and industrial applications. It uses a bi-periodic structure with constant impedance. It consists of a buncher section with three-cells and on-axis coupled cavities with nine-cells. The total length is 740.0 mm including the electron gun. Using SUPERFISH, HFSS and PARMELA codes, it is capable to deliver 4.5 MeV ...

We consider a nonlinear lattice of the Klein—Gordon type analysing envelope solitons created on a standing carrier wave. In particular, we show that nonlinear wavesofsuch a kind are described by a system of two coupled nonlinear Schrodinger equations and we find a new class of its solutions which describe bound states of two dark-profile solitons. As particular cases, this solution includes non...

Over the past decade, standing-wave photoemission (SW-XPS) has evolved into a powerful and versatile non-destructive technique for probing element-specific electronic, magnetic, and structural properties of buried layers and interfaces with sub-nanometer depth resolution. In this article, I will discuss several promising future directions in this emergent field stemming from experimental and th...

On the basis of observations of arterial pulse forms in anesthetized dogs, a hypothesis is developed to account for the genesis of the aortic standing wave which is responsible for the dicrotic characteristics of pulses recorded from the abdominal-femoral system. A sudden lowering of resistance to pulse wave propagation in the region of the diaphragm and an increase in resistance in the periphe...
