Electron Accelerations at High Mach Number Shocks: Two-Dimensional Particle-In-Cell Simulations in Various Parameter Regimes [PDF]
, 2012 Electron accelerations at high Mach number collision-less shocks are investigated by means of two-dimensional electromagnetic Particle-in-Cell simulations with various Alfven Mach numbers, ion-to-electron mass ratios, and the upstream electron beta_e (the ratio of the thermal pressure to the magnetic pressure).

Earth's Future, Volume 10, Issue 12, December 2022., 2022 Abstract Anthropogenic greenhouse gas emissions are causing unprecedented changes to the climate. In 2015, at the United Nations (UN) Conference of the Parties in Paris, France, countries agreed to limit the global mean temperature (GMT) increase to 2°C above preindustrial levels, and to pursue efforts to limit warming to 1.5°C.

Magnetic Field and Faraday Rotation Measure in the Turbulent Warm Ionized Medium [PDF]
, 2014 Wu et al. (2009) suggested an empirical relation between the magnetic field strength along the line of sight (LOS) and the dispersion of Faraday rotation measure (RM) distribution in turbulent media with root-mean-square sonic Mach number $M_s \simeq 1$. In this paper, we extend the work by incorporating the Mach number dependence. Media with $\sim 0.5

Nanosecond Hyperquenching for Electron Cryo‐Microscopy Without Air‐Water Interface Artifacts
Chemistry – A European Journal, EarlyView.A novel method for the ultrafast vitrification of the biological assemblies is assayed by the electron cryotomography. Protein specimens prepared by this method inherently lack the spatial/structural artifacts, which derive from the surface tension at the air‐water interface (AWI).

Needle detection and localisation for robot‐assisted subretinal injection using deep learning
CAAI Transactions on Intelligence Technology, EarlyView., 2023 Abstract Subretinal injection is a complicated task for retinal surgeons to operate manually. In this paper we demonstrate a robust framework for needle detection and localisation in robot‐assisted subretinal injection using microscope‐integrated Optical Coherence Tomography with deep learning.
