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.

There's another season of "Made in Abyss" on Netflix!
The show was an incredible bait and switch. It had this cutesy look and a very interesting world to explore. But each episode got darker end the end of season 1 was pure body horror.

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 EVs are outdated as fast as cell phones and depreciate just as fast.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…

The first amendment is measurably under attack in ways it has not been since the presidency of Richard Nixon.
A double standard has also emerged:
if you protest, criticize, or publicly object to the president’s agenda, you’re a target.
Katherine Jacobsen, the project coordinator for the Committee to Protect Journalists in the US, Canada and Caribbean region, said:
“The thing with the first amendment and free speech in general is that you have to respect everyone’s rig…

trending hashtag #spacex and my 1st thought is „what did Musk do now?“ but I was positively surprised. It’s a really neat video 💥

I've managed to install the Stirling PDF tools on one of our company's mini PCs using #podman. I've tried doing it with Redhat's cockpit admin GUI but it didn't really work, probably because of SELinux or something (it's always SELinux...). I found some instruction for the commandline that worked.
This is all seems like a good use-case for Docker but the whole contain…
