Noncoherent MIMO Communications: Theoretical Foundation, Design Approaches, and Future Challenges
Noncoherent communication is a promising paradigm for future wireless systems where acquiring accurate channel state information (CSI) is challenging or infeasible. It provides methods to bypass the need for explicit channel estimation in practical scenarios such as high-mobility networks, massive distributed antenna arrays, energy-constrained Internet-of-Things devices, and unstructured propagation environments. This survey provides a comprehensive overview of noncoherent communication strateg…

In non-defence sectors, domestic output has slumped: throughout the first half of 2025, production of televisions and washing machines fell by 30 per cent, footwear by 29 per cent and refrigerators by 12 per cent

Russia's reckoning is coming
Beyond the bluster of his meeting with President Trump, Vladimir Putin is in trouble. Isolated, outmanoeuvred, and stalled on the battlefield, Russia is tottering financially and militarily, while Zelensky's Ukraine continues to hold the upper hand.

A Novel Cost-Effective MIMO Architecture with Ray Antenna Array for Enhanced Wireless Communication Performance
This paper proposes a novel multi-antenna architecture, termed ray antenna array (RAA), which practically enables flexible beamforming and also enhances wireless communication performance for high frequency systems in a cost-effective manner. RAA consists of a large number of inexpensive antenna elements and a few radio frequency (RF) chains. These antenna elements are arranged in a novel ray like structure, where each ray corresponds to one simple uniform linear array (sULA) with a carefully d…

"The Fed sees elevated consumer prices and increased inflation ahead as the trade war intensifies. Prior to Trump, the average tariff on stuff coming into America was 2.3%. Now it’s topped 17%, which is the highest since 1934 (a year of intense misery and suffering). Given the ‘deals’ Trump has just made, that rate is set to crest above 19% – the stiffest since 1906. That’s when this guy was president. Nice stash. "

We are barely 6 months into #TheAmericanFascist Presidency and we already find ourselves with fundamental rights in the American Constitution under direct threat and the power of the judiciary to enforce and check the power of the President being pulled back.
And Democratic Party members seem to be all talk and very very little action or leadership to counter this.
Are they waiting for the midterms to take back Congress?
At this pace, surely they see the risk that there may not BE midterms. Or that the results are negated, disputed or invalidated.
I can’t fathom how they are not removing themselves from Congress now in protest and calling for a general protest/strike of all freedom loving Americans to restore the constitution, force the Trump appointed fascist enabling judges to resign, and force Trump and his Administration to go.
July 4th is coming. Independence Day? Or not? Democracy or not?

Conference vignette 👀: #OpenScience is about much more than #OpenData. Presenting unpublished work is also Openness, as social science alumna Dr. Ros Attenborough reminded us. And if you can share that way, then...
In the Presidential symposium, another lab alumnus introduced a mouse protein that massively affected the clock ⏰ . His group found it through an ambitious phosphoproteomic 🧪 candidate selection approach on a cell line 🧫 , looking beyond the canonical idea of the clockwork (TTFL in the jargon). Canonical here means canonised by a Nobel prize.
A good friend from Japan explained in the Q&A that his group had just found the SAME gene in a genetic screen of mice 🐁with altered sleep patterns 🐁💤🛌. We know the clock controls sleep. So, independent evidence across continents.👍
Over dinner they started to coordinate how they would each publish their work. #Science working.

Conversational Alignment with Artificial Intelligence in Context
The development of sophisticated artificial intelligence (AI) conversational agents based on large language models raises important questions about the relationship between human norms, values, and practices and AI design and performance. This article explores what it means for AI agents to be conversationally aligned to human communicative norms and practices for handling context and common ground and proposes a new framework for evaluating developers' design choices. We begin by drawing on th…

Zero-Shot Semantic Communication with Multimodal Foundation Models
Most existing semantic communication (SemCom) systems use deep joint source-channel coding (DeepJSCC) to encode task-specific semantics in a goal-oriented manner. However, their reliance on predefined tasks and datasets significantly limits their flexibility and generalizability in practical deployments. Multi-modal foundation models provide a promising solution by generating universal semantic tokens. Inspired by this, we introduce SemCLIP, a zero-shot SemCom framework leveraging the contrasti…
