New Phytologist, Volume 248, Issue 4, Page 1639-1654, November 2025.Summary The physiological significance of lithium (Li+) remains largely unexplored in plants despite its consistent presence in at least trace concentrations in plant tissues. While Li+ has traditionally been associated with salinity‐like stress symptoms and presumed to utilise sodium (Na+) transport pathways, accumulating evidence points to multiple ...

A cloud collision model for water maser excitation
The Astrophysical Journal, 1986 High-velocity collisions between small, dense, neutral clouds or between a dense cloud and a dense shell can provide the energy source required to excite H2O maser emission. The radiative precursor from the surface of the collisional shock front rapidly diffuses through the cloud, heating the dust grains but leaving the H2 molecules cool.

Evolution of the outflow traced by water masers in the evolved star IRAS 18043 - 2116
, 2022 We present the spectral and spatial evolution of H2O masers associated with IRAS 18043-2116, a well-known water fountain hosting a high-velocity collimated jet, which has been found in the observations with the 45 m telescope of Nobeyama Radio ...

The Astrophysical JournalHenize 2–10 is a dwarf galaxy experiencing positive black hole (BH) feedback from a radio-detected low-luminosity active galactic nucleus. Previous Green Bank Telescope (GBT) observations detected a H _2 O “kilomaser” in Henize 2–10, but the low angular ...

Risk Analysis, Volume 45, Issue 11, Page 3519-3532, November 2025.ABSTRACT Decisions about how to respond to coastal flood hazards often involve disagreements over resource allocations. In the United States, large intergovernmental fiscal transfers have enabled rebuilding in areas that experience severe repetitive losses. This case study focuses on Ortley Beach, a barrier island neighborhood in Toms River, New Jersey,

Water masers in the Local Group of galaxies
, 2020 . We compare the number of detected 22 GHz H 2 O masers in the Local Group galaxies M31, M33, NGC 6822, IC 10, IC 1613, DDO 187, GR8, NGC 185, and the Magellanic Clouds with the water maser population of the Milky Way.

Water vapor masers in stars departing from the AGB
, 2002 The 22 GHz water vapor masers of four “non-variable” OH/IR stars considered to be young Proto-Planetary Nebulae (PPNs) were monitored for more than 10 years. In two of them, OH 15.7+0.

The Astronomical JournalAccurate astrometric measurements for star-forming regions located on the far side of the Milky Way remain scarce. In this work, we present the astrometric results for a 22 GHz water maser associated with star-forming region G040.96+02.48 located on the ...

Ecology, Volume 106, Issue 10, October 2025.Abstract Spatial resource heterogeneity (SRH; the variable spatial distribution of resources) is a surprisingly understudied component of oscillatory predator–prey dynamics. SRH may be particularly important in large, ecologically realistic networks where different patterns of resource distribution can manifest, which have important implications for ...

SWAG Water Masers in the Galactic Center
, 2018 The Galactic Center contains large amounts of molecular and ionized gas as well as a plethora of energetic objects. Water masers are an extinction-insensitive probe for star formation and thus ideal for studies of star formation stages in this highly ...
