La guerre, ascenseur social pour une partie de la population russe
Une étude publiée par l’Institut français des relations internationales décrit l’impact socio-économique du conflit avec l’Ukraine, qu’il s’agisse des emplois générés par le complexe militaro-industriel ou des salaires et primes distribués aux soldats.

Sur trois prises de position éthiques de Bibliosuisse
La récente prise de position de la commission Éthique professionnelle1 de Bibliosuisse concernant la neutralité des bibliothèques m'a rappelé l'existence de précédents documents du même type, et j'ai eu l'envie de les commenter en tant que professionnel et citoyen. Avant de commencer, je précise que la commission fait globalement du très bon travail, mais que certains détails suscitent chez moi des questions…

Distributed Activity Detection for Cell-Free Hybrid Near-Far Field Communications
A great amount of endeavor has recently been devoted to activity detection for massive machine-type communications in cell-free massive MIMO. However, in practice, as the number of antennas at the access points (APs) increases, the Rayleigh distance that separates the near-field and far-field regions also expands, rendering the conventional assumption of far-field propagation alone impractical. To address this challenge, this paper considers a hybrid near-far field activity detection in cell-fr…

An Integrated Sensing and Communication System for Time-Sensitive Targets with Random Arrivals
In 6G networks, integrated sensing and communication (ISAC) is envisioned as a key technology that enables wireless systems to perform joint sensing and communication using shared hardware, antennas and spectrum. ISAC designs facilitate emerging applications such as smart cities and autonomous driving. Such applications also demand ultra-reliable and low-latency communication (URLLC). Thus, an ISAC-enabled URLLC system can prioritize time-sensitive targets and ensure information delivery under …

Waymo’s robotaxis are coming back to New York City
Waymo applied for a permit to test autonomous vehicles with safety drivers in New York City. And it hopes it can change the state law to allow it to operate fully driverless.

After nuclear weapons testing began in 1945, atmospheric radiation contaminated new steel production worldwide.
For decades, scientists needing radiation-free metal for sensitive instruments had to salvage steel from pre-war shipwrecks.
Scientists called this steel
"low-background steel."
Graham-Cumming sees a parallel with today's web, where AI-generated content increasingly mingles with human-created material and contaminates it.
With the advent o…

Scientists once hoarded pre-nuclear steel; now we’re hoarding pre-AI content
Newly announced catalog collects pre-2022 sources untouched by ChatGPT and AI contamination.

Serving Large Language Models on Huawei CloudMatrix384
The rapid evolution of large language models (LLMs), driven by growing parameter scales, adoption of mixture-of-experts (MoE) architectures, and expanding context lengths, imposes unprecedented demands on AI infrastructure. Traditional AI clusters face limitations in compute intensity, memory bandwidth, inter-chip communication, and latency, compounded by variable workloads and strict service-level objectives. Addressing these issues requires fundamentally redesigned hardware-software integrati…

Widely Linear Augmented Extreme Learning Machine Based Impairments Compensation for Satellite Communications
Satellite communications are crucial for the evolution beyond fifth-generation networks. However, the dynamic nature of satellite channels and their inherent impairments present significant challenges. In this paper, a novel post-compensation scheme that combines the complex-valued extreme learning machine with augmented hidden layer (CELMAH) architecture and widely linear processing (WLP) is developed to address these issues by exploiting signal impropriety in satellite communications. Althoug…
