Re‐Ontologizing Leadership Identity for Sustainable Business: Embedding Leaders' Decarbonization Competences in Bahrain's Sunset Industry

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The lag in embedding leaders' decarbonization competences into sunset industry businesses (oil, gas, and petroleum), particularly in Middle Eastern hydrocarbon economies, poses an existential environmental and institutional challenge. In many such contexts, leaders' decarbonization competences remain subordinated to resource utilization and ...

Fading AGN Candidates: AGN Histories and Outflow Signatures∗

open access: yesThe Astrophysical Journal, 2017
Abstract We consider the energy budgets and radiative history of eight fading active galactic nuclei (AGNs), identified from an energy shortfall between the requirements to ionize very extended (radius > 10 kpc) ionized clouds and the luminosity of the nucleus as we view it directly.

Porous Ag/NiO Nanosheet Catalysts With Electronic Metal–Support Interaction for Efficient Soot Oxidation via a NOx‐Assisted Mechanism

open access: yesCarbon and Hydrogen, EarlyView.
Ag nanoparticles dispersed on porous NiO nanosheets via GBMR method deliver superior soot oxidation performance at 359°C, where Ag–NiO interaction promotes interfacial oxygen activation and NOx‐assisted mechanism, offering design principles for advanced emission control technologies.

The Close AGN Reference Survey (CARS): a comparison between sub-mm and optical AGN diagnostic diagrams [PDF]

open access: yes
The LIR − LHCN relation suggests that there is a tight connection between dense gas and star formation. We use data from the Close AGN Reference Survey (CARS) to investigate the dense gas - star formation relation in AGN hosting galaxies, and the use of ...

Identifying Active Galactic Nuclei at z ∼ 3 from the HETDEX Survey Using Machine Learning

open access: yesThe Astronomical Journal, 2023
We used data from the Hobby–Eberly Telescope Dark Energy Experiment (HETDEX) to study the incidence of AGN in continuum-selected galaxies at z ∼ 3.

Efficacy and safety of fenfluramine in Dravet syndrome: The impact of patient clinical characteristics

open access: yesEpilepsia Open, EarlyView.
This graphical abstract provides an overview of the content from this post hoc analysis evaluating the efficacy and safety of fenfluramine in patients with Dravet syndrome stratified by age, number of previously attempted antiseizure medications, and SCN1A pathogenic variant status using data pooled from the three pivotal randomized controlled trials ...

The Close AGN Reference Survey (CARS)

open access: yes, 2017
The role of active galactic nuclei (AGN) in the evolution of galaxies remains a mystery. The energy released by these accreting supermassive black holes can vastly exceed the entire binding energy of their host galaxies, yet it remains unclear how this ...

Circular Polarisation in AGN [PDF]

open access: yesPublications of the Astronomical Society of Australia, 2002
AbstractWe discuss the constraints that recent observations place on circular polarisation in AGN. In many sources the circular polarisation is variable on short timescales, indicating that it originates in compact regions of the sources. The best prospects for gleaning further information about circular polarisation are high resolution VLBI and ...
