Fiberoptics technology and its application to propulsion control systems [PDF]
Electro-optical systems have many advantages over conventional electrical systems. Among these are optics' insensitivity to electro-magnetic interference, good electrical isolation and the ability to make measurements in highly explosive areas without ...

The United States Magnetotelluric Array and the National Impedance Map
Reviews of Geophysics, Volume 64, Issue 2, June 2026.Abstract The United States Magnetotelluric Array (USMTArray) data set, collected in the years 2006–2024, consists of more than 1,700 long‐period magnetotelluric stations covering the entirety of the contiguous United States on a quasi‐regular 70 km grid.

Acta Physiologica, Volume 242, Issue 6, June 2026.ABSTRACT Aim The alkali cation/proton exchanger NHE6/SLC9A6 regulates luminal pH homeostasis and trafficking of recycling endosomes in most tissues, especially neurons. Loss‐of‐function mutations in NHE6 cause Christianson Syndrome, an X‐linked neurodevelopmental and neurodegenerative disorder; however, the underlying molecular and cellular mechanisms ...

Wilson's Atmospheric Electron Accelerator: A Centennial Perspective
Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract As of the time of writing this letter, we mark the centennial of Wilson's runaway electrons proposed in 1925. Owing to instrumentation limitations, Wilson and his students could not detect the particles anticipated by theory Chilingarian et al. (2025, https://doi.org/10.1029/2024jd042350).

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.Abstract The return stroke in a cloud‐to‐ground (CG) flash is initiated when the downward leader either reaches the ground or connects with an upward leader from a grounded structure. Unlike negative downward leaders, which typically propagate in a highly branched manner, downward positive leaders (DPLs) can propagate either in a branched or unbranched

Lightning Outbreaks at the Mature Stage of Tropical Cyclone: Case Study for Hurricane Dorian (2019)
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.Abstract The relationship between tropical cyclone (TC) lightning activity and intensity change has been examined for nearly 30 years, yet a clear consensus remains elusive, reflecting the complexity of the processes governing TC lightning. This study investigates the physical mechanisms that triggered inner‐core lightning outbreaks during the mature ...
