Intensity scaling limitations of laser-driven proton acceleration in the TNSA-regime

open access: yesPhysical Review Research, 2022
We report on experimental results on laser-driven proton acceleration using high-intensity laser pulses. We present power law scalings of the maximum proton energy with laser pulse energy and show that the scaling exponent ξ strongly depends on the scale

Vertical evolution of auroral acceleration at substorm onset [PDF]

open access: yes, 2009
This study describes the onset process of auroral substorms in connection with the vertical evolution of auroral particle acceleration, on the basis of auroral kilometric radiation (AKR) dynamics.

The effects of walking speed and mobile phone use on the walking dynamics of young adults

open access: yesScientific Reports, 2021
Walking while using a mobile phone has been shown to affect the walking dynamics of young adults. However, this has only been investigated using treadmill walking at a fixed walking speed.

An Adaptively Accelerated Bayesian Deblurring Method with Entropy Prior

open access: yesEURASIP Journal on Advances in Signal Processing, 2008
The development of an efficient adaptively accelerated iterative deblurring algorithm based on Bayesian statistical concept has been reported. Entropy of an image has been used as a “prior” distribution and instead of additive form, used in ...

Correlation Analysis between Rail Track Geometry and Car-Body Vibration Based on Fractal Theory

open access: yesFractal and Fractional, 2022
The effect of track geometry on vehicle vibration is a major concern in high-speed rail (HSR) operation from the perspectives of ride comfort and safety. However, how to quantitatively characterize the relation between them remains a problem to be solved

Energetic Neutral Atoms from Solar Energetic Particles due to Shocks: Inclusion of Upstream Particles

open access: yesThe Astrophysical Journal, 2023
Many aspects of solar energetic particles are not well understood, including their acceleration mechanism. There has been recent interest in the potential of energetic neutral atoms (ENAs) as remote probes of solar energetic particles (SEPs) and their ...
