Nanoscale Graphene‐Based Ballistic Rectifiers for Detection of High Terahertz Frequency Optical Signals

Small Science, Volume 6, Issue 4, April 2026.
Ballistic graphene rectifier capable of operating at frequencies up to 3 THz, engineered through asymmetric nanojunction geometries in high‐mobility monolayer graphene encapsulated in hexagonal boron nitride Graphene exhibits the longest carrier mean free path of any known electronic material, yet only a few device concepts have successfully leveraged ...

ULF Wave Modulation of Energetic Electron Precipitation Caused by the Self‐Limiting of Space Radiation: May 2024 Superstorm Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The May 2024 geomagnetic superstorm provided the opportunity to explore how strong wave‐particle interactions affect energetic electron precipitation under intense driving. Using coordinated measurements from a balloon‐borne Timepix‐based X‐ray detector, ground‐based riometers and magnetometers, and Arase satellite observations, we identified ...

Monitoring Groundwater Pumping Using Time‐Lapse Tomography From Ambient Seismic Noise

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Management of water resources will be of critical importance as the effects of climate change accelerate. This implies the need to monitor water resources with high spatial and temporal resolution. One way to meet this need could be passive seismic methods using ambient seismic noise. In this study, we present a novel approach using time‐lapse

Phase angle, impedance ratio, and athletic performance of young adult Japanese track and field throwers

Physiological Reports, Volume 14, Issue 7, April 2026.
Abstract This study investigated the relationship between World Athletics (WA) points and body size, body composition, phase angle (PhA), and impedance ratio (IR) among young adult Japanese university track and field throwing athletes. Twenty‐five female and 39 male athletes (11 and 14 javelin throwers, 5 and 13 discus throwers, 6 and 7 hammer throwers,

Changes in the mechanical properties of tendon structures in lower limbs during repetitive contractions in male long‐distance runners

Physiological Reports, Volume 14, Issue 7, April 2026.
Abstract The purposes of this study were to compare mechanical properties of tendon structures during single and repetitive contractions between long‐distance runners (LDR) and untrained males (UTM) and to verify the relationship between changes in mechanical properties of tendon structures during repetitive contractions and running performance in LDR.

Monitoring Near‐Surface Changes Using Anthropogenic Seismic Vibrations

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The abundance of anthropogenic seismic noise provides a valuable resource for monitoring dynamic subsurface property changes. We utilize railway and wind turbine‐induced vibrations recorded by a geophone array to estimate surface wave attenuation and velocity in the underlying glacial deposits of Illinois.

Helically Magnetized Plasma: From Photonic Fermi‐Arc Metal to Chirality‐Free Uniaxial Medium

Nanophotonics, Volume 15, Issue 5, 16 March 2026.
A helically modulated magnetic field in magnetized plasma realizes a photonic Fermi‐arc metal, enabling full analytical tracking of Weyl node evolution. As modulation strengthens, opposing‐chirality Fermi arcs hybridize and recombine, yielding a chirality‐free uniaxial optical medium without conventional node annihilation.
