Distributed Surface Inspection via Operational Modal Analysis by a Swarm of Miniaturized Vibration-Sensing Robots
Robot swarms offer the potential to serve a variety of distributed sensing applications. An interesting real-world application that stands to benefit significantly from deployment of swarms is structural monitoring, where traditional sensor networks face challenges in structural coverage due to their static nature. This paper investigates the deployment of a swarm of miniaturized vibration sensing robots to inspect and localize structural damages on a surface section within a high-fidelity simu…

Does Movable Antenna Present A Dual-edged Nature? From the Perspective of Physical Layer Security: A Joint Design of Fixed-position Antenna and Movable Antenna
In conventional artificial noise (AN)-aided physical-layer security systems, fixed-position antenna (FPA) arrays exhibit inherent vulnerability to coverage gaps due to their static spatial configuration. Adversarial eavesdroppers can strategically exploit their mobility to infiltrate these spatial nulls of AN radiation patterns, thereby evading interference suppression and successfully intercepting the confidential communication. To overcome this limitation, in this paper, we investigate a hybr…

Ich konnte neulich nicht mehr rein weil die schon in den Umzugsvorbereitungen waren.
tbh hat die Stadt aber auch null Flair. Ist halt eine Bergbaustadt... Die Natur drum herum ist das Erlebnis :)

Schweden versetzt eine 600 Tonnen schwere Kirche in einem Stück – und macht ein Spektakel daraus
Im nordschwedischen Kiruna steht ein historisches Ereignis bevor: Die mehr als 100 Jahre alte Kirche wird an einen neuen Standort versetzt. Und Zuschauer aus aller Welt können dabei zusehen.

Unpopular Opinion: Ich persönlich mag #TheLänd. Ich finde, Jung von Matt hat mit der Idee einen echten Coup gelandet. Werbeexperten sehen das ähnlich.
Andere denken bei The Länd eher - hä?
Nur den #NettHier-Sticker, den lieben ca. alle.

"The Länd" - wie erfolgreich die Werbung ist, weiß keiner, aber jeder kennt sie
Seit 2021 wirbt Baden-Württemberg mit der "The-Länd"-Kampagne um ausländische Fachkräfte. Weil unklar ist, ob das geklappt hat, gibt es neben positiven Stimmen aber auch Kritik.

Neither Valid nor Reliable? Investigating the Use of LLMs as Judges
Evaluating natural language generation (NLG) systems remains a core challenge of natural language processing (NLP), further complicated by the rise of large language models (LLMs) that aims to be general-purpose. Recently, large language models as judges (LLJs) have emerged as a promising alternative to traditional metrics, but their validity remains underexplored. This position paper argues that the current enthusiasm around LLJs may be premature, as their adoption has outpaced rigorous scruti…

On the nature and charge state of the X-Defect, a radiation-induced Silicon defect with field-enhanced charge carrier emission
The elusive X-Defect, a defect found in low-resistivity $p$-type Silicon after irradiation, observed as a low-temperature shoulder of the $\mathrm{B}_\mathrm{i}\mathrm{O}_\mathrm{i}$ defect (Boron-interstitial-Oxygen-interstitial complex) in Thermally Stimulated Current (TSC) measurements, was investigated to determine its properties, matching them with those of a previously identified defect. Through a combination of TSC, Deep-Level Transient Spectroscopy (DLTS), Difference-DLTS (DDLTS), numer…

Learning from nature: insights into GraphDOP's representations of the Earth System
Through a series of experiments, we provide evidence that the GraphDOP model - trained solely on meteorological observations, using no prior knowledge - develops internal representations of the Earth System state, structure and dynamics as well as the characteristics of different observing systems. Firstly, we demonstrate that the network constructs a unified latent representation of the Earth System state which is common across different observation types. For example, cloud structures maintai…

Kreml: Brauchen Zeit, um Trumps Aussagen zu prüfen
Der Kreml hat die jüngsten Äußerungen von US-Präsident Donald Trump zum Krieg in der Ukraine als "sehr ernst" bezeichnet und eine Analyse angekündigt. "Die Äußerungen des US-Präsidenten sind sehr ernst. Einige von ihnen sind persönlich an Präsident Putin gerichtet", sagte Kreml-Sprecher Dmitri Peskow. Man benötige Zeit, um die Aussagen zu prüfen. Präsident Wladimir Putin werd…

Dwarf galaxies in non-local gravity
The nature of dark matter remains one of the most pressing open questions in modern cosmology. Despite extensive experimental efforts, no direct or indirect detection of dark matter particles has been confirmed. This has motivated alternative approaches, including modifications to the underlying theory of gravity. In this work, we investigate the implications of a specific non-local gravity (NLG) theory, which modifies General Relativity by introducing non-local effects that manifest as an effe…

Soliton-like Rogue Wave Dynamics in Dissipative Higher-Order NLS Models: A Floquet Spectral Perspective
We investigate rogue wave formation and spectral downshifting in the higher-order nonlinear Schrödinger (HONLS) equation and its dissipative extensions: the nonlinear mean-flow damping model (NLD-HONLS) and the viscous damping model (V-HONLS). By applying Floquet spectral analysis, we characterize i) the structural organization of the dynamical background and ii) the nature of the rogue waves that appear, distinguishing sharply localized, soliton-like structures from more diffuse, spatially ex…
