GALEX J194419.33+491257.0: An unusually active SU UMa-type dwarf nova with a very short orbital period in the Kepler data [PDF]

, 2014
We studied the background dwarf nova of KIC 11412044 in the Kepler public data and identified it with GALEX J194419.33+491257.0. This object turned out to be a very active SU UMa-type dwarf nova having a mean supercycle of about 150 d and frequent normal

Dose‐Dependent Effects of Biochar on Soil Revealed by Fast Field‐Cycling (FFC) NMR: From Molecular Water Dynamics to Soil Functionality

Magnetic Resonance in Chemistry, Volume 64, Issue 3, Page 349-364, March 2026.
Dose–response of biochar in a clay soil: fifteen mixtures (fBC 0–1) reveal nonlinear thresholds (pH/EC) and sharp WHC gains near fBC ≈ 0.3–0.5. Coupled FT‐IR and FFC‐NMR (0.01–10 MHz; ModelFree τc distributions) link water dynamics to soil functionality.

Accurate pre- and post-eruption orbital periods for the dwarf/classical nova V1017 Sgr [PDF]

, 2016
V1017 Sgr is a classical nova (in 1919) that displayed an earlier dwarf nova eruption (in 1901), and two more dwarf nova events (in 1973 and 1991). Previous work on this bright system in quiescence (V=13.5) has only been a few isolated magnitudes, a few ...

Developing an understanding of American elderberry (Sambucus nigra subsp. canadensis (L.) Bolli) to support breeding efforts

Crop Science, Volume 66, Issue 1, January/February 2026.
Abstract Elderberries (Sambucus spp.) have been valued as food and medicine around the world for millennia. Elderberry products are experiencing an increase in demand as ongoing research substantiates their putative health benefits. European elderberries (Sambucus nigra subsp. nigra) are an established industry in Europe and are often imported into the

Resolving different sources of fast X-ray variability of the dwarf nova RU Peg in quiescence [PDF]

, 2013
We analysed an X-ray light curve of the dwarf nova RU Peg taken by XMM-Newton with a duration of 46300 s. The power density spectrum has a complicated shape with two red noise and two white noise components, indicating the presence of two turbulent ...

Only One Percent of Important Shark and Ray Areas in the Western Indian Ocean Are Fully Protected From Fishing Pressure

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Delineation of Important Shark and Ray Areas (ISRAs) In the Western Indian Ocean was enhanced by the verification and incorporation of unpublished records. Even with this expanded dataset, ~99% of ISRA coverage fell outside of fully protected, no‐take MPAs.
