The quasi-biennial oscillation (QBO) is a nearly periodic reversal in the equatorial stratospheric zonal winds, characterised by alternating easterly and westerly regimes over an average period of ...

Figure 1: Graphene-clad silicon photonic crystal nanostructures. Figure 4: Parametric four-wave mixing in graphene-clad silicon nanocavities. We have demonstrated, for the first time, a hybrid ...

The film explores the nature of sound waves, demonstrating how sound travels as a wave through air, which acts as a medium. It illustrates sound generation using a loudspeaker, examines oscillation, ...

Using light pulses, scientists have recently managed to control theta oscillations in mouse brain. They discovered that these brain waves coordinate movement - enabling signaling between distant brain ...

Scientists have recently found that the temperatures in Saturn's equatorial atmosphere oscillate with a period of about 15 Earth years. The temperature swing's signal was detected by analyzing ...

ABSTRACT The North Atlantic Oscillation (NAO) response to the northeast Pacific climate variability is examined using the ERA-40 dataset. The main objective is to validate a mechanism involving ...

KUNMING -- Chinese researchers have recently studied the structure of chromospheric umbral waves in sunspots and discovered the driving source of umbral waves, according to the Yunnan Observatories ...
