Selection of Biofortified Sweet Potato (Ipomoea batatas L.) Genotypes in Response to Drought Stress

Journal of Agronomy and Crop Science, Volume 211, Issue 3, May 2025.
ABSTRACT The development of orange‐ and purple‐fleshed sweet potato genotypes with high nutritional quality and drought tolerance is paramount in the face of climate changes and exponential human population growth. Therefore, the objective was to select biofortified sweet potato genotypes tolerant to drought. Eight progenies developed by the NEOSC‐UFSC

Molecular Clouds in Dwarf Irregular Galaxies [PDF]

Highlights of Astronomy, 1989
The study of molecular clouds in dwarf galaxies was, until recently, an arduous task and provided detections in only a handful of sources (see Thronson and Bally 1986; Wiklind et al. 1986; Tacconi and Young 1987; Arnoult et al. 1988). Line strengths observed in CO were small (<100mK) and measurements were confined to one position per source, thus ...

Multi‐Source Forecast of Solar Cycle Flare Activity Using the Novel Informer‐Based Models

Space Weather, Volume 23, Issue 4, April 2025.
Abstract Solar flares, the significant indicators of solar activity, have an impact on Earth's satellites and communication systems. Accurate prediction of solar flare events is crucial for mitigating these effects. In this work, we use multiple data sources, including Geostationary Operational Environmental Satellites soft X‐ray flare flux and the ...

‘The non‐dormant beast’: Antisemitism in communities of Russian nationalists on Vkontakte

Nations and Nationalism, Volume 31, Issue 2, Page 361-377, April 2025.
Abstract The article explores the specifics of Russian antisemitic discourse of recent years using the example of three nationalist communities on Vkontakte, the most popular Russian social networking site, by means of critical discourse analysis. The main strategies they employ to frame the Jews online are stereotyping Jews as ungrateful and greedy ...

Magnetic Fields in the Irregular Galaxy LMC [PDF]

Symposium - International Astronomical Union, 1993
New radio continuum surveys allowed the determination of the magnetic field in the Large Magellanic Cloud. The magnetic field is filamentary, extending to the south of the 30 Doradus nebula. Some possible explanations for this unusual morphology are discussed.

Stochastic Quantum Mechanics in Curved Spaces: Application to Schwarzschild Black Holes

Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.
ABSTRACT In this work, we start from the hypothesis that the universe lives in a Gravitational Wave Background (GWB). From this hypothesis, it follows that space–time is not locally flat because we have to take into account the fluctuations of the GWB in space–time. This implies that sufficiently small particles will feel these oscillations, preventing

Transcriptomic Dysregulation in Animal Models of Attention‐Deficit Hyperactivity Disorder and Nicotine Dependence Suggests Shared Neural Mechanisms

Brain and Behavior, Volume 15, Issue 3, March 2025.
Around 50% of people with attention‐deficit hyperactivity disorder (ADHD) develop nicotine dependence (ND); however, the mechanism for this relationship is unknown, and current treatments for ADHD do not prevent or slow the onset of ND. Transcriptomic analysis of the striatum and whole brains of three rodent models of ADHD and two of ND supports a role

Statistics of HI Extents of Irregular Galaxies [PDF]

Symposium - International Astronomical Union, 1996
Using the 3.′2 Arecibo beam, we have mapped the HI envelopes of a sample of 70 irregular galaxies (Sdm, Sm, Im and BCD), including 45 from the Virgo Cluster Catalog, 14 Field galaxies at similar redshifts, and 11 Nearby dwarfs chosen to give a complete sample out to 6 Mpc, within the Arecibo declination range.

A γ-Ray-emitting Collisional Ring Galaxy System in Our Galactic Neighborhood

The Astrophysical Journal Letters
The astrophysical γ -ray photons carry the signatures of the violent phenomena happening on various astronomical scales in our Universe. This includes supernova remnants, pulsars, and pulsar wind nebulae in the Galactic environment and extragalactic ...
