Geheimdienst in Südkorea: Nordkorea sendet zusätzliche Truppen nach Russland
Nordkorea könnte nach Angaben aus Südkorea schon bald zusätzliche Truppen nach Russland als Unterstützung für eine neue Offensive im Krieg gegen die Ukraine entsenden. Die zusätzlichen Truppen könnten bereits im Juli oder August nach Russland verlegt werden, teilten südkoreanische Abgeordnete nach einer nichtöffentlichen Geheimdienst-Anhörung im Parl…

Measurement-based quantum computation with variable-range interacting systems
We demonstrate that weighted graph states (WGS) generated via variable-range interacting Ising spin systems where the interaction strength decays with distance as a power law, characterized by the fall-off rate, can successfully implement single- and two-qubit gates with fidelity exceeding classical limits by performing suitable measurements. In the regime of truly long-range interactions (small fall-off rate), optimizing over local unitary operations, while retaining the local measurement sche…

Transient Dynamics in Lattices of Differentiating Ring Oscillators
Recurrent neural networks (RNNs) are machine learning models widely used for learning temporal relationships. Current state-of-the-art RNNs use integrating or spiking neurons -- two classes of computing units whose outputs depend directly on their internal states -- and accordingly there is a wealth of literature characterizing the behavior of large networks built from these neurons. On the other hand, past research on differentiating neurons, whose outputs are computed from the derivatives of …

The JWST/AURORA Survey: Multiple Balmer and Paschen Emission Lines for Individual Star-forming Galaxies at z=1.5-4.4. I. A Diversity of Nebular Attenuation Curves and Evidence for Non-Unity Dust Covering Fractions
We present the nebular attenuation curves and dust covering fractions for 24 redshift z=1.5-4.4 star-forming galaxies using multiple Balmer and Paschen lines from the JWST/AURORA survey. Nebular reddening derived from Paschen lines exceeds that from Balmer lines for at least half the galaxies in the sample when assuming the commonly-adopted Galactic extinction curve, implying the presence of optically-thick star formation. The nebular attenuation curves exhibit a broad range of normalizations (…
