A small and vigorous black hole in the early Universe
(2024-03-07)Several theories have been proposed to describe the formation of black hole seeds in the early Universe and to explain the emergence of very massive black holes observed in the first thousand million years after the Big ... -
The morphological mix of dwarf galaxies in the nearby Universe
(2024-03-01)We use a complete, unbiased sample of 257 dwarf (10 8 M < M < 10 9.5 M) galaxies at z < 0.08, in the COSMOS field, to study the morphological mix of the dwarf population in low-density environments. Visual inspection of ... -
Sustainable bio-based solid phase extraction adsorbent for the determination of various types of organic compounds
(2024-02-21)A sustainable, bio-based, mesoporous material, Starbon A800, was explored for use as an adsorbent in solid phase extraction (SPE). A solution containing seven nitrosamines was first used as a standard to optimise conditions ... -
Stimuli‐Responsive Polymers for Engineered Emulsions
(2024-05)Emulsions are complex. Dispersing two immiscible phases, thus expanding an interface, requires effort to achieve and the resultant dispersion is thermodynamically unstable, driving the system toward coalescence. Furthermore, ... -
How do international student returnees contribute to the development of their home countries? A systematic mapping and thematic synthesis
(2024-03-04)This study investigates the significant yet under-examined role of international student returnees in catalysing societal development in their home countries. Through systematic mapping and thematic synthesis of 53 articles ... -
Pathogen lifestyle determines host genetic signature of quantitative disease resistance loci in oilseed rape ( Brassica napus )
(2024-03-02)Using associative transcriptomics, our study identifies genes conferring resistance to four diverse fungal pathogens in crops, emphasizing key genetic determinants of multi-pathogen resistance. Crops are affected by several ... -

(2024-02-16)In the published article, there was an error in the Ethics statement. The correct Ethics statement appears below. The studies involving human participants were reviewed and approved by the Medical Research Committee, Hamad ... -
Guidance to inform research recruitment processes for studies involving critically ill patients
(2024-02-28)Clinical research in intensive care units (ICUs) is essential for improving treatments for critically ill patients. However, invitations to participate in clinical research in this situation pose numerous challenges. Studies ... -
Investigation of the Effect of Substitutions on the Electronic and Optical Properties of the Sumanene Molecule
(2024-01-01)Sumanene (C21H12) is the smallest bowl-shaped molecule containing a central benzene ring, alternately surrounded by another 3 benzene rings and cyclopentadiene rings. This study investigated the effect of various electron ... -
Inside the bubble: exploring the environments of reionisation-era Lyman-α emitting galaxies with JADES and FRESCO⋆
(2024-02-01)We present a study of the environments of 17 Lyman-α emitting galaxies (LAEs) in the reionisation-era (5.8 < z < 8) identified by JWST/NIRSpec as part of the JWST Advanced Deep Extragalactic Survey (JADES). Unless situated ... -
Examining the nature of the ultraluminous X-ray source Holmberg II X-1
(2024-02-06)We present a comprehensive spectral analysis of the ultraluminous X-ray source Holmberg II X-1 using broadband and high-resolution X-ray spectra taken with the XMM-Newton satellite over a period of 19 yr, taking advantage ... -
Problematic pornography use across countries, genders, and sexual orientations: Insights from the International Sex Survey and comparison of different assessment tools
(2024-02-27)Background and aims: Problematic pornography use (PPU) is a common manifestation of the newly introduced Compulsive Sexual Behavior Disorder diagnosis in the 11th edition of the International Statistical Classification of ... -
Finding AGN remnant candidates based on radio morphology with machine learning
(2023-04-12)Context. Remnant radio galaxies represent the dying phase of radio-loud active galactic nuclei (AGN). Large samples of remnant radio galaxies are important for quantifying the radio-galaxy life cycle. The remnants of ... -
The association between the sense of control and depression during the COVID-19 pandemic: a systematic review and meta-analysis
(2024)Introduction: High levels of depression and low sense of control have been reported during the COVID-19 pandemic. The removal of typical freedoms through public health restrictions may have played an important role. The ... -
