Testing cosmic-ray acceleration with radio relics: a high-resolution study using MHD and tracers
, 2016 Weak shocks in the intracluster medium may accelerate cosmic-ray protons and cosmic-ray electrons differently depending on the angle between the upstream magnetic field and the shock normal.

Constraints on cosmic ray loading and PeV neutrino production in blazars
, 2017 IceCube has detected a cumulative flux of PeV neutrinos, which origin is unknown. Blazars, active galactic nuclei with relativistic jets pointing to us, are long and widely expected to be one of the strong candidates of high energy neutrino sources.

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review
Journal of Field Robotics, EarlyView.ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers
River Research and Applications, EarlyView.ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

Science Education, EarlyView.ABSTRACT Over the past decades, science education research has extensively examined the role of metaphors in teaching and learning science. However, much of the existing research has focused on verbal manifestations of metaphors, thereby overlooking aspects of metaphors that may occur in non‐verbal form. This study reconceptualises metaphors as dynamic

Small, EarlyView.Traditional single‐cell analysis lacks the capacity for real‐time monitoring. This study presents Microfluidic dielectrophoretic Arresting System (MiDAS), a microelectrofluidic platform using dielectrophoresis for single‐cell and droplet trapping. MiDAS immobilizes diverse samples (cells, beads, droplets) for optical imaging and Raman spectroscopy. Its
