Energetic Compact Strokes as the Major Source of Downward Terrestrial Gamma‐Ray Flashes in Winter Thunderstorms

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract Terrestrial gamma‐ray flashes (TGFs) are short bursts of intense gamma radiation associated with lightning discharges. Although thousands of TGFs have been observed from space, TGFs detected at ground level, known as downward TGFs, are still very limited, and their relationship with lightning discharge processes remains elusive. Here we report

Testing solar lepton mixing sum rules in neutrino oscillation experiments [PDF]

, 2014
A bstractSmall discrete family symmetries such as S4, A4 or A5 may lead to simple leading-order predictions for the neutrino mixing matrix such as the bimaximal, tribimaximal or golden ratio mixing patterns, which may be brought into agreement with ...

Intermediate Fluence Downward Terrestrial Gamma Ray Flashes as Observed by the Telescope Array Surface Detector

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 24, 28 December 2024.
Abstract On 11 September 2021, two small thunderstorms developed over the Telescope Array Surface Detector (TASD) that produced an unprecedented number of six downward terrestrial gamma ray flashes (TGFs) within one‐hour timeframe. The TGFs occurred during the initial stage of negative cloud‐to‐ground flashes whose return strokes had increasingly large

The evolution and history of Vinca alkaloids: From the Big Bang to the treatment of pediatric acute leukemia

Pediatric Blood &Cancer, Volume 71, Issue 11, November 2024.
Abstract An attractive flower from the island of Madagascar has in part saved the lives of thousands of children with acute lymphoblastic leukemia (ALL). Random mutations and alterations to the genome led to the evolution of genes encoding enzymes, which would provide the periwinkle flower an arsenal of secondary metabolites to survive within the ...

Recent Developments in Halide Perovskite Nanocrystals for Indirect X‐ray Detection

Advanced Materials Technologies, Volume 9, Issue 20, October 21, 2024.
Perovskite nanocrystals act as scintillators under X‐ray illumination with different conversion yield, stability, or decay times and outperform commercial materials, depending on their composition, host matrix, and luminescence process. Besides the lead halide perovskites, there are lead‐free alternatives providing self‐trapped exciton emission ...
