A century after Albert Einstein said we would never be able to observe the instantaneous velocity of tiny particles as they randomly shake and shimmy (in so-called Brownian motion), physicist Mark ...

Figure 1: Schematic characteristic timescales of Brownian motion in different regimes. Figure 2: Schematic of the experimental set-up and upconversion luminescence measurements of the NaYF ...

An international team of scientists, which included researchers from Nanjing Tech University, used a simple but powerful technique called luminescence spectroscopy to measure the velocities of tiny ...

Thanks for your great work. I am really into your paper MeanFlow and I have a question regarding it. Based on my understanding, your MeanFlow Identity and your formulation do not seem to depend on the ...

Abstract: Plane-wave and divergent-wave ultrasound imaging can speed up Doppler measurements compared to methods that use a sharp transmit beam. However, conventional pulsed Doppler and color Doppler ...
