Using multilayer socioecological networks to assess ecosystem service flow in a subsistence farming community in Papua New Guinea

People and Nature, Volume 8, Issue 4, Page 854-870, April 2026.
Abstract Ecosystem services are rapidly degrading under anthropogenic pressure. Therefore, it is increasingly important to understand how ecosystem services flow, particularly at local scales, where people directly rely on nature for their livelihoods and well‐being. Many ecosystem services are underpinned by ecological (e.g.

VLBI study of maser kinematics in high-mass SFRs. I. G16.59-0.05

, 2010
The present paper focuses on the high-mass star-forming region G16.59-0.05. Methods: Using the VLBA and the EVN arrays, we conducted phase-referenced observations of the three most powerful maser species in G16.59-0.05: H2O at 22.2 GHz (4 epochs), CH3OH ...

From the ashes: JVLA observations of water fountain nebula candidates show the rebirth of IRAS 18455+0448 [PDF]

, 2014
[abridged] The class of water fountain nebulae is thought to represent the stage of the earliest onset of collimated bipolar outflows during the post-Asymptotic Giant Branch phase.

Frequency Extensions of Auroral Kilometric Radiation: The Key to Unlocking Earth's Radio Response to Substorms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Auroral kilometric radiation (AKR) provides a sensitive probe of magnetospheric dynamics during substorms. We analyze an extended data set of AKR bursts observed by the WIND spacecraft to investigate how the frequency structure of AKR responds to substorm onset and evolution.

Water masers in the Kronian system [PDF]

Proceedings of the International Astronomical Union, 2009
AbstractThe presence of water has been considered for a long time as a key condition for life in planetary environments. The Cassini mission discovered water vapour in the Kronian system by detecting absorption of UV emission from a background star (Hansen et al. 2006).

Comparing image quality of synchrotron and laboratory nano‐CT scans: a round robin study

Journal of Synchrotron Radiation, Volume 33, Issue 2, Page 489-507, March 2026.
A multi‐facility round‐robin comparison of synchrotron‐ and laboratory‐based nano‐computed tomography using a standardized 3D phantom reveals superior resolution and acquisition speed at synchrotrons, while advanced laboratory systems achieve competitive image quality with extended scan times; phase contrast modalities further enhance structural ...

A renewed search for water maser emission from Mira variables [PDF]

, 1997
There is an approximately 60% detection rate for 1612 MHz masers in association with red, color-selected IRAS sources, though few are detected from the bluer circumstellar shells of Mira variables. On the other hand and complementarily, past, pre-IRAS 22
