High-speed train operations confront a range of aerodynamic challenges, particularly when traversing confined tunnel environments. The phenomenon of tunnel pressure waves, which originates from the ...

Background and aims: We have shown, in lavaged rabbits, that High-Amplitude Bubble-Continuous Positive Airway Pressure (HAB-CPAP, see figure) provides greater gas exchange and lower work of breathing ...

The massive eruption from the underwater Tonga volcano in the Pacific earlier this year generated a blast so powerful, it sent massive pressure waves rippling through the atmosphere and around the ...

"Plastronic waves traveled along the water, the superhydrophobic surface and the gas layer 45 times faster than capillary waves normally do," Nieminen says. Setting a wave speed record is only part of ...

Even under the cover of darkness, mosquitoes are surprisingly difficult to swat, and we may be closer to understanding why. They sense and exploit the airflow created by a swatter moving at speed and ...
