A Quantised Push‐Sum Distributed Adaptive Momentum Algorithm for Optimisation Over Directed Networks

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT In this paper, we investigate a distributed constrained optimisation problem over directed networks. The agents in the networks conduct local computations and communications, endeavouring to collaboratively minimise the aggregation of all locally known convex cost functions subject to a global constraint set.

Crystal structure of the plant GABA aminotransferase AtGABA‐T from Arabidopsis thaliana

Acta Crystallographica Section F, EarlyView.
The crystal structure of A. thaliana γ‐aminobutyric acid aminotransferase (GABA‐T) reveals that plant GABA‐T belongs to the class III aminotransferase family and employs a C‐terminal arginine residue for γ‐aminobutyric acid recognition, in contrast to the N‐terminal arginine used by class II enzymes.γ‐Aminobutyric acid aminotransferase (GABA‐T) is a ...

From talking tools to metahumans: social interaction, semiotic skill, and the authority of AI chatbots Des outils parlants aux métahumains : interactions sociales, compétences sémiotiques et autorité des robots conversationnels

Journal of the Royal Anthropological Institute, EarlyView.
What does it take to turn a tool into a talking tool and that into an ultimate authority? Generative artificial intelligence (GenAI) in its diverse forms, such as large language models (LLMs), is celebrated as a useful tool. But LLM‐based conversational agents, or chatbots, the software applications through which ordinary users are likely to engage ...

SMART CITY CONTROL ROOMS: The Rewiring of Local Governance Landscapes in India

International Journal of Urban and Regional Research, EarlyView.
Abstract Smart city control rooms are prominent components of the smart city discourse. They embody a long‐standing dream to visualize and manage multiple urban processes in real time through the collation of data flows. Previous research has produced important insights into the design, construction and operation of these facilities.

CONSULTANCY STATE: Government as (a) Service and the Anti‐politics of Technological Expertise in Indian Cities

International Journal of Urban and Regional Research, EarlyView.
Abstract This article analyses ideas of ‘good governance through technology’ in India that first emerged from the software industry, symbolizing state support for the ‘new middle‐class’ values of liberalized private enterprise. We suggest that the contemporary prominence of consulting firms in government represents a second transformation that embeds ...

The Coloniality of Data: Police Databases and the Rationalization of Surveillance from Colonial Vietnam to the Modern Carceral State

The British Journal of Sociology, EarlyView.
ABSTRACT Tracing the early adoption of computer gang databases by the Los Angeles County Sheriff's Department and the Los Angeles Police Department in the 1980s to the deployment of computationally‐assisted surveillance during the Vietnam War, this paper uses a genealogical approach to compare surveillance technologies developed across the arc of ...

Decentralized propaganda in the era of digital media: The massive presence of the Chinese state on Douyin

American Journal of Political Science, EarlyView.
Abstract The rise of social media in the digital era poses unprecedented challenges to authoritarian regimes that aim to influence public attitudes and behaviors. To address these challenges, we argue that authoritarian regimes have adopted a decentralized approach to produce and disseminate propaganda on social media.
