Effect of Intercropping Beans with Maize and Botanical Extract on Fall Armyworm (Spodoptera frugiperda) Infestation

open access: yesInternational 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.

Black hole, neutron star, and white dwarf merger rates in AGN discs [PDF]

open access: yes, 2020
Advanced LIGO \& Advanced Virgo are detecting a large number of binary stellar origin black hole (BH) mergers. A promising channel for accelerated BH merger lies in active galactic nucleus (AGN) disks of gas around super-masssive black holes.

Why Do Black--Hole X-ray Binaries Tend to Be Transient? [PDF]

open access: yes, 1999
Black hole X-ray binaries are transient probably because their discs are subject to the same thermal-viscous instability which is present in dwarf nova binary systems.

A Review of Vector-Borne Rice Viruses

open access: yesViruses, 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 ...

Genomic Regions Related to White/Black Tail Feather Color in Dwarf Chickens Identified Using a Genome-Wide Association Study

open access: yesFrontiers in Genetics, 2021
Although the genetic foundation of chicken body feather color has been extensively explored, that of tail feather color remains poorly understood. In the present study, we used a synthetic chicken dwarf line (DW), derived from hybrids bred between a ...

Overexpression of rice black-streaked dwarf virus p7-1 in Arabidopsis results in male sterility due to non-dehiscent anthers. [PDF]

open access: yesPLoS ONE, 2013
Rice black-streaked dwarf virus (RBSDV), a member of the genus Fijivirus in the family Reoviridae, is propagatively transmitted by the small brown planthopper (Laodelphax striatellus Fallén).

Hierarchical merger of primordial black holes in dwarf galaxies

open access: yesJournal of Cosmology and Astroparticle Physics, 2022
Abstract We study the merger history of primordial black holes (PBHs) in a scenario where they represent the dominant dark matter component of a typical dwarf galaxies' core. We investigate the possibility of a sequence of collisions resulting in a hierarchical merger of black holes, and look at the final mass spectrum in such clusters ...

Identification and Characterization of a Large Sample of Distant Active Dwarf Galaxies in XMM-SERVS

open access: yesThe 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.

Revealing the intermediate-mass black hole at the heart of the dwarf galaxy NGC 404 with sub-parsec resolution ALMA observations [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2020
We estimate the mass of the intermediate-mass black hole at the heart of the dwarf elliptical galaxy NGC 404 using Atacama Large Millimetre/submillimetre Array (ALMA) observations of the molecular interstellar medium at an unprecedented linear ...
