This paper examines the effect of current-induced breaking on the modeling of wave breaking dissipation near rip currents. Simulations using a set of existing wave transformation models are compared to existing laboratory measurements made on a bar/channel topography in the presence of both strong and weak rip currents. The model/data comparisons demonstrate that existing models can effectively...

The novel PQ mechanism replaces the strong CP problem with some challenges in a model building. In particular, arise regarding i) origin of an anomalous global symmetry called symmetry, ii) scale breaking, and iii) quality symmetry. this letter, we provide natural simple UV completed that addresses these challenges. Extra quarks anti-quarks are separated by two branes Randall-Sundrum R4×S1/Z2 s...

An uncontroversial observation of adjoint string breaking is proposed, while measuring the static potential from Wilson loops only. The overlap of the Wilson loop with the broken-string state is small, but non-vanishing, so that the broken-string groundstate can be seen if the Wilson loop is long enough. We demonstrate this in the context of the (2 + 1)d SU(2) adjoint static potential, using an...

Breaking waves have ability to transport large quantities of sediment and significant impact on coastal structures morphology. Hence, modeling of wave breaking is an important subject in coastal and marine engineering. In this research, the periodic wave breaking process on a plane slope is studied experimentally and numerically. Laboratory experiments were conducted to record water surface ele...

Ratchet is a device that produces direct current of particles when driven by an unbiased force. We demonstrate a simple scattering quantum ratchet based on an asymmetrical quantum tunneling effect in two-dimensional electron gas with Rashba spin-orbit interaction (R2DEG). We consider the tunneling of electrons across a square potential barrier sandwiched by interface scattering potentials of un...

⎯ Despite the fact that minimally invasive robotic surgery provides many advantages for patients like reduced trauma and shorter recovery times, the lack of force feedback complicates the application of available surgery systems. We present an evaluation platform which emulates the functionality of such a system. Additionally it is extended by a high fidelity force sensory and feedback. For eva...

To solve the problem of coverage performance assessment, this study proposes an evaluation method based on the trajectory of the target, which is applicable to universal sensor networks, including both heterogeneous and homogeneous sensor networks. Different from the traditional Voronoi algorithm, the proposed Improved Coverage Force Division (ICFD) plans a coverage force division map whichscal...
