Fundamental Hydraulic Geometry Relations as an Accessible Tool for Identifying Channel Instability Over National Scales

River Research and Applications, EarlyView.
ABSTRACT The geometry of alluvial river channels can give insight into their stability, which can inform predictions of morphological change, flood risk and ecological degradation. Fundamental hydraulic geometry relations can be used to estimate the equilibrium dimensions of stable river channels by evaluating the balance between the erodibility of bed

Competition Policy and Achieving Sustainable Development Goal 1 (No Poverty): The Role of Mergers and Acquisitions Adjudications in South Africa

Sustainable Development, EarlyView.
ABSTRACT South Africa faces persistently high poverty and inequality alongside a highly concentrated economic structure, raising questions about whether merger control, especially public‐interest provisions, can contribute to poverty reduction. However, empirical evidence directly linking merger adjudication outcomes to poverty remains limited.

On-axis Polarization Calibration of the FAST L-band 19-beam Receiver

The Astronomical Journal
We present the polarization calibration of the 19-beam receiver at 1420 MHz within the full illumination of the Five-hundred-meter Aperture Spherical radio Telescope from 2018 October to 2023 March.

Urban Housing Markets and Sustainability Risk: Empirical Evidence From South African Cities

Sustainable Development, EarlyView.
ABSTRACT Despite the global shift toward sustainability and rising expectations for socially and environmentally responsible housing, evidence from South Africa's urban markets remains limited and underexplored. This study examines how sustainability‐related vulnerabilities shape downside housing risk across 60 cities between 2002 and 2021.

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Habitat Features, Coyotes, and Humans Drive Diel Activity Variation Among Sympatric Mammals

Integrative Zoology, EarlyView.
We found that multiple mammal species show considerable variation in diel activity in response to several factors, with biotic variables (habitat features and the presence of coyotes Canis latrans) having the strongest overall effects. Our results have important implications for trophic dynamics. Future studies will need to account for these underlying

Tales of Cyberspace and Artificial Intelligence: Diverging Stakeholderships?

Global Policy, EarlyView.
ABSTRACT This article traces the evolution of the Internet from the 1990s to the 2020s and compares it with the development of Artificial Intelligence (AI), particularly following the public launch of ChatGPT in late 2022. It identifies both parallels and divergencies between these two overlapping technological domains, focusing on the growing ...

Aligning Transnational due Diligence: The EU Deforestation Regulation and Brazil's Fragmented Beef Governance

Global Policy, EarlyView.
ABSTRACT Transnational due diligence regulations, such as the European Union Regulation on Deforestation‐Free Products (EUDR), are reshaping sustainability governance by transforming voluntary norms into binding global rules. Yet, their effectiveness depends on how well they align with domestic governance systems and on the power asymmetries that ...

Genomic Assessment of Reintroduced African Wild Dogs Informs Conservation Translocations

Animal Conservation, EarlyView.
Few reintroduction and translocation programs incorporate genomic assessments into management planning, despite ongoing debate over how founder individuals should be selected. Here, we assess the genomic composition of reintroduced African wild dog (Lycaon pictus) populations in private reserves in South Africa, comparing them with a free‐roaming ...

Infection control in the brain and the eye

Acta Ophthalmologica, EarlyView.
Abstract The Central Nervous System (CNS), comprising the brain and the eye, is considered to have a ‘privileged’ mechanism for dealing with immunological challenge (immune privilege, IP). CNS IP has been revealed through experiments using foreign protein antigens and cell and tissue alloantigens (grafts), but evidence for a role for IP in modulating ...
