Leaky Wave Antennas for Next Generation Wireless Applications in sub-THz Frequencies: Current Status and Research Challenges
The ever-growing demand for ultra-high data rates, massive connectivity, and joint communication-sensing capabilities in future wireless networks is driving research into sub-terahertz (sub-THz) communications. While these frequency bands offer abundant spectrum, they also pose severe propagation and hardware design challenges, motivating the search for alternative antenna solutions beyond conventional antenna arrays. Leaky-wave antennas (LWAs) have emerged as a promising candidate for sub-THz …

Was removing some snails from the greenhouse. Opened skylight to fling them over the fence (into an uncultivated garden) and the window collapsed on my head! No injury as I was wearing a cap and the glass didn't break. Mortice joint had rotted through. Greenhouse was quite old when we arrived 40 years ago and I keep replacing bits.
Luckily I'd kept a partially rotten roof spar so was able to cut it down, using the sound part and joint it to fit.
Never throw anything that …

Ultraviolet radiation and neutrinos: two messengers from CCSNe in the CSM scenario
Massive stars (>8 $M_{\odot}$) often undergo intense mass loss through winds or eruptive events in the final stages of their evolution, leading to the formation of a dense circumstellar medium (CSM). This material, expelled months to years before core collapse, shapes the pre-explosion environment and influences the early supernova (SN) emission. In particular, the interaction of the SN ejecta with the dense CSM can power an extended emission into the UV/optical bands, as seen in a growing frac…

Ich habe heute #MdRnH extra einen Schlenker über #Marienbrücke und Antonstraße gemacht und der Stau war nicht schlimmer als sonst auch. 🤷

Advent, Advent, das Bremslicht brennt: Marienbrücke einspurig!
Mit der Eröffnung des Striezelmarktes ist auch die Marienbrücke nur einspurig befahrbar – wie auch schon letztes Jahr. Ein Streit- und Stau-Thema in der Stadt! Baubürgermeister Stephan Kühn wünscht sich das als Dauerlösung, Untersuchungen hätten gezeigt, dass es dadurch nur wenige Sekunden Verzögerung bei der Brückenquerung gäbe. Doch dem widerspricht Stadtrat Holger Zastrow nach einem aktuellen Praxistest vehement: “In der Woche vor der Sperrung der Autospur benötigte man in de…

TAIBOM: Bringing Trustworthiness to AI-Enabled Systems
The growing integration of open-source software and AI-driven technologies has introduced new layers of complexity into the software supply chain, challenging existing methods for dependency management and system assurance. While Software Bills of Materials (SBOMs) have become critical for enhancing transparency and traceability, current frameworks fall short in capturing the unique characteristics of AI systems -- namely, their dynamic, data-driven nature and the loosely coupled dependencies a…

A General Optimization Framework for Movable Antenna Systems via Discrete Sampling
Movable antenna (MA) systems have attracted growing interest in wireless communications due to their ability to reshape wireless channels via local antenna movement within a confined region. However, optimizing antenna positions to enhance communication performance turns out to be challenging due to the highly nonlinear relationship between wireless channels and antenna positions. Existing approaches, such as gradient-based and heuristic algorithms, often suffer from high computational complexi…

Cryogenic growth of aluminum: structural morphology, optical properties, superconductivity and microwave dielectric loss
We explore the molecular beam epitaxy synthesis of superconducting aluminum thin films grown on c-plane sapphire substrates at cryogenic temperatures of 6 K and compare their behavior with films synthesized at room temperature. We demonstrate that cryogenic growth increases structural disorder, producing crystalline grains that modify the optical, electrical, and superconducting properties of aluminum. We observe that cryogenic deposition changes the color of aluminum from fully reflective to y…

The Role of Acoustic Instability in Cosmic-Ray Self-Confinement
Over the past decades, there has been growing observational and theoretical evidence that cosmic-ray-induced instabilities play an important role in both acceleration and transport of cosmic rays (CRs). For instance, the efficient acceleration of charged particles at supernova remnant shocks requires rapidly growing instabilities, so much so that none of the proposed processes seem sufficient to warrant acceleration to PeV energies. In this work, we investigate whether an acoustic instability t…
