As low as 2 W threshold power is obtained in several centimeters long waveguide. In one aspect, a method includes propagating a first wave along an axis of a multimode waveguide in a forward direction, the first optical wave having a first frequency; propagating a second wave along the axis...
The El Niño/Southern Oscillation is characterized by irregular warm (El Niño) and cold (La Niña) events in the tropical Pacific Ocean, which have substantial global environmental and socioeconomic impacts. These events are generally attributed t

shock-waveunsteady flowlaser Doppler velocimetryThe purpose of the present study is to investigate two-dimensional unsteady transonic flows in a channel with a sonic throat and a moderately strong normal shock downstream of the throat. The aim of the present work is to obtain a precise description...
Inertial oscillations, inertial waves and the initial value problem in a rotating annular channel are investigated for an arbitrarily small but fixed Ekman number E. We first derive the inviscid solution of inertial oscillations and inertial waves, as well as an asymptotic expression for the viscous...

The North Atlantic Oscillation and the Arctic Oscillation are modes of climate variability affecting temperature and precipitation in the mid-latitudes. Here we use reanalysis data and climate model simulations of historical and warm climates to show tha
Nowadays, a prime technology in generation IV nuclear reactors, the supercritical water reactor (SCWR), is the main object of focus. The current article aims to develop a thermal hydraulic numerical model for predicting density wave oscillation (DWO) in a supercritical water natural circulation loop...
Although the structure of the device in this study is also a submerged heaving plate structure, there are some key differences. Firstly, the function of the device is different. The device is the energy capture structure of the wave energy converter, and we conduct basic research on wave energ...
