Satellite Signal Detection via Rydberg-Atom Receiver
Rydberg-atom receivers aim for ultra-high sensitivity to microwave fields through various techniques, but receiving satellite signals has remained a significant challenge, due to the difficulty of capturing weak microwaves over long distances. In this work, we introduce a high-gain antenna to focus satellite signals, and then apply into an atomic cell via a microwave cavity. Using microwave-enhanced coupling, the minimum detectable power of incident microwave is down to -128 dBm, and the corres…

Neue Studie: Mikroplastik beeinflusst Wirkung von Antibiotika
Mikroplastik bindet Antibiotika und kann so deren Wirkung hemmen. Das haben Forscher in Wien nun gezeigt. Was das für die Therapie und die Entstehung von Resistenzen bedeutet.

While trying out simple #macrophotography gear on my balcony in Bochum, Germany, I caught a tiny (only a millimeter or so) #spider constructing a little web, no more than 5 cm in diameter - and catching a tiny fly almost immediately. Nature's drama at home ... ;-) Panasonic #Lumix DMC-FZ300 with DMW LC-55 close-up lens, either at maximum optical zoom or somewhat into digital. Bright sunlight in the afternoon.

I never thought about this. EVs are outdated as fast as cell phones and depreciate just as fast.

MIMO Systems Aided by Microwave Linear Analog Computers: Capacity-Achieving Architectures with Reduced Circuit Complexity
To meet the demands of future wireless networks, antenna arrays must scale from massive multiple-input multiple-output (MIMO) to gigantic MIMO, involving even larger numbers of antennas. To address the hardware and computational cost of gigantic MIMO, several strategies are available that shift processing from the digital to the analog domain. Among them, microwave linear analog computers (MiLACs) offer a compelling solution by enabling fully analog beamforming through reconfigurable microwave …

Detecting Hardware Trojans in Microprocessors via Hardware Error Correction Code-based Modules
Software-exploitable Hardware Trojans (HTs) enable attackers to execute unauthorized software or gain illicit access to privileged operations. This manuscript introduces a hardware-based methodology for detecting runtime HT activations using Error Correction Codes (ECCs) on a RISC-V microprocessor. Specifically, it focuses on HTs that inject malicious instructions, disrupting the normal execution flow by triggering unauthorized programs. To counter this threat, the manuscript introduces a Hardw…

Effect of Signal Quantization on Performance Measures of a 1st Order One Dimensional Differential Microphone Array
In practical systems, recorded analog signals must be digitized for processing, introducing quantization as a critical aspect of data acquisition. While prior studies have examined quantization effects in various signal processing contexts, its impact on differential microphone arrays (DMAs), particularly in one-dimensional (1D) first-order configurations, remains unexplored. This paper investigates the influence of signal quantization on performance of first-order 1D DMAs across various beampa…

❝I’d mostly discount the idea that this is largely about AI displacing educated workers.❞
YES. THANK YOU.
“AI is here doooom!! doooom!!” is such a common knee-jerk excuse for the miserable college grad job market right now, and…I don’t see it. In terms of real, actual, yes-it-worked, yes-you-can-clearly-replace-whole-highly-skilled-jobs successes inside of real actual businesses…I   just   don’t   see   it.
Whatever’s going on, the AIpocalypse is an •excuse•, not a •cause• here.

Microplastics and melting ice reveal deepening crisis in Antarctica
Glaciers melting rapidly, fields of moss expanding, water streaming off ice shelves once frozen solid: these are just a few of the impacts of climate change observed by a team of 57 researchers during a 70-day voyage around the Antarctic coast on the Russian icebreaker Akademik Tryoshnikov. The expedition also revealed the presence of microplastics […]
