International Journal of Agronomy, 2020 African farmers are currently grappling with potential control measures for the invasive fall armyworm (FAW) (Spodoptera frugiperda), which has recently emerged as an important economic pest that is ravaging maize fields across the continent.

A Review of Vector-Borne Rice Viruses
Viruses, 2022 Rice (Oryza sativa L.) is one of the major staple foods for global consumption. A major roadblock to global rice production is persistent loss of crops caused by plant diseases, including rice blast, sheath blight, bacterial blight, and particularly ...

Detection of compact objects by means of gravitational lensing in binary systems [PDF]
, 2002 We consider the gravitational magnification of light for binary systems containing two compact objects: white dwarfs, a white dwarf and a neutron star or a white dwarf and a black hole.

Dwarf galaxies and the black hole scaling relations [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2020 ABSTRACT The sample of dwarf galaxies with measured central black hole masses M and velocity dispersions σ has recently doubled, and gives a close fit to the extrapolation of the M - σ relation for more massive galaxies. We argue that this is difficult to reconcile with suggestions that the scaling relations between galaxies and their ...

Infrared signature of active massive black holes in nearby dwarf galaxies [PDF]
, 2017 We investigate the possible presence of active galactic nuclei (AGN) in dwarf galaxies and other nearby galaxies to identify candidates for follow-up confirmation and dynamical mass measurements.

Identification and Characterization of a Large Sample of Distant Active Dwarf Galaxies in XMM-SERVS
The Astrophysical Journal, 2023 Active dwarf galaxies are important because they contribute to the evolution of dwarf galaxies and can reveal their hosted massive black holes. However, the sample size of such sources beyond the local universe is still highly limited.

QPOs in Cataclysmic Variables and in X-ray Binaries [PDF]
, 2005 Recent observations, reported by Warner and Woudt, of Dwarf Nova Oscillations (DNOs) exhibiting frequency drift, period doubling, and 1:2:3 harmonic structure, can be understood as disc oscillations that are excited by perturbations at the spin frequency

Black dwarf supernova in the far future [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT In the far future, long after star formation has ceased, the universe will be populated by sparse degenerate remnants, mostly white dwarfs, though their ultimate fate is an open question. These white dwarfs will cool and freeze solid into black dwarfs while pycnonuclear fusion will slowly process their composition to iron-56 ...

Hunting for massive black holes in dwarf galaxies [PDF]
Nature Astronomy, 2022 Despite traditional thinking, an appreciable population of massive black holes may be lurking in dwarf galaxies. Prior to the last decade, nearly all massive black holes were found in the nuclei of giant galaxies and the existence of massive black holes in dwarf galaxies was highly controversial.

Acta Agrobotanica, 2018 Selected cultivars of Asian brassicacean vegetables were evaluated for their yield potential and susceptibility to bacterial infection. Chinese broccoli, two cultivars of Chinese cabbage (‘Dwarf milk cabbage’ and improved ‘Tahtsai’), and mizuna were ...
