Trump kündigt Waffenlieferungen an Ukraine über NATO an
Die USA werden der Ukraine künftig Waffen über die NATO liefern. Das Bündnis bezahle die Waffen vollständig, sagte US-Präsident Donald Trump dem Sender NBC News. "Wir schicken Waffen an die NATO, und die NATO wird die vollen Kosten für diese Waffen erstatten."
Erstmals seit seiner Rückkehr ins Amt will Trump Waffen in die Ukraine schicken. Dafür soll eine besondere Voll…

Solving excited states for long-range interacting trapped ions with neural networks
The computation of excited states in strongly interacting quantum many-body systems is of fundamental importance. Yet, it is notoriously challenging due to the exponential scaling of the Hilbert space dimension with the system size. Here, we introduce a neural network-based algorithm that can simultaneously output multiple low-lying excited states of a quantum many-body spin system in an accurate and efficient fashion. This algorithm, dubbed the neural quantum excited-state (NQES) algorithm, re…

Assessing the Alignment of Audio Representations with Timbre Similarity Ratings
Psychoacoustical so-called "timbre spaces" map perceptual similarity ratings of instrument sounds onto low-dimensional embeddings via multidimensional scaling, but suffer from scalability issues and are incapable of generalization. Recent results from audio (music and speech) quality assessment as well as image similarity have shown that deep learning is able to produce embeddings that align well with human perception while being largely free from these constraints. Although the existing human-…

Bar-driven dispersal of Galactic substructure
Galactic archaeologists often assume that integrals of motion (IoMs) such as $L_z$ and $E$ are conserved, so substructure remains frozen in IoM space over many Gyr. However, this is not true in the Milky Way due in part to its rotating bar. In this study we quantify the effects of the bar on the dynamics of substructure. We employ three different theoretical models: an analytical toy model; a set of test particle simulations with steady and slowing bars; and a cosmological zoom-in simulation of…

Normalized Radon Cumulative Distribution Transforms for Invariance and Robustness in Optimal Transport Based Image Classification
The Radon cumulative distribution transform (R-CDT), is an easy-to-compute feature extractor that facilitates image classification tasks especially in the small data regime. It is closely related to the sliced Wasserstein distance and provably guaranties the linear separability of image classes that emerge from translations or scalings. In many real-world applications, like the recognition of watermarks in filigranology, however, the data is subject to general affine transformations originating…

UNHCR: Fast zehn Millionen Ukrainer geflüchtet
Die russische Invasion in die Ukraine hat laut dem UN-Flüchtlingshilfswerk (UNHCR) bislang fast zehn Millionen Menschen zur Flucht aus ihren Häusern gezwungen. Rund 3,8 Millionen der Betroffenen seien Binnenvertriebene, 5,6 Millionen ins Ausland geflohen, teilte die UNHCR-Repräsentantin für das Land, Karolina Lindholm Billing, der Nachrichtenagentur AP mit. "Aktuell bleiben die m…

LoRAShield: Data-Free Editing Alignment for Secure Personalized LoRA Sharing
The proliferation of Low-Rank Adaptation (LoRA) models has democratized personalized text-to-image generation, enabling users to share lightweight models (e.g., personal portraits) on platforms like Civitai and Liblib. However, this "share-and-play" ecosystem introduces critical risks: benign LoRAs can be weaponized by adversaries to generate harmful content (e.g., political, defamatory imagery), undermining creator rights and platform safety. Existing defenses like concept-erasure methods focu…

Stark Tuning and Charge State Control in Individual Telecom C-Band Quantum Dots
Telecom-wavelength quantum dots (QDs) are emerging as a promising solution for generating deterministic single-photons compatible with existing fiber-optic infrastructure. Emission in the low-loss C-band minimizes transmission losses, making them ideal for long-distance quantum communication. In this work, we present the first demonstration of both Stark tuning and charge state control of individual InAs/InP QDs operating within the telecom C-band. These QDs are grown by droplet epitaxy and emb…
