Abstract: We present a traveling wave analysis of a general class of semiconductor ... The formalism of the quantum mechanical treatment has a built-in relationship between the relative intensity ...

Rather than addressing the problem as oscillations in a discrete system, we model the swing dynamics as a propagating electro-mechanical wave using a partial differential equation. A ring geometry ...

Sound, one of the most ubiquitous physical forces in nature, is a compressional mechanical wave that transmits oscillating and fluctuating pressure through substances, researchers note.

Covid-19 wave in Asia is making headlines again as cases spike in Hong Kong, Singapore, China, and Thailand, raising new concerns. Despite the summer season, when viruses usually decline, these ...

Still, temperatures that feel like late July for a four-day stretch had them calling it a heat wave. "I think it's in the eye of the beholder," said Ken Blumenfeld, a senior climatologist with the ...

Poundland’s exit from Chiswick comes as part of a wider wave of closures sweeping the UK. Later this month, the Brackla store in Wales will also vanish from the high street, with its final ...

Enigmatic because of their quantum nature—meaning that they behave as both particles and waves—atoms had never ... ability to share the same quantum mechanical wave. Atoms in this type of ...

Since sound is made up of mechanical waves that travel through substances like air, water or tissue, the researchers designed a system to "bathe cultured cells in acoustic waves". "In this study ...
