Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

Acoustic Tweezers‐Assisted Biomaterial Molding in Petri Dishes (TAMP) for Engineering Glioma Tissues With Controlled Cellular and Extracellular Matrix Architectures

Small, EarlyView.
This study introduces an acoustics‐assisted tissue engineering approach, termed “Acoustic Tweezers‐Assisted Biomaterial Molding in Petri Dishes (TAMP),” which enables the fabrication of tissues with customizable extracellular matrix (ECM) geometries and various acoustically constructed internal cellular architectures, including parallel elongated ...

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

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.

Introduction: Towards a linguistic anthropology of AI Introduction : vers une anthropologie linguistique de l'IA

Journal of the Royal Anthropological Institute, EarlyView.
This essay introduces the themed cluster of articles, ‘Towards a linguistic anthropology of AI’. The advent of artificial intelligence (AI), especially in large language models capable of producing coherent discourse mimicking conversational interaction, is exerting unprecedented pressure on prevailing concepts of language, personhood, and the human ...

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 ...

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 ...
