A grand-design spiral galaxy with an ordered magnetic field at redshift 2.6 as resolved with ALMA and gravitational lensing

Autor: de Roo, W., Vegetti, S., Powell, D. M., Ndiritu, S. W., Pakmor, R., McKean, J. P.

Magnetic fields play an important role in the evolution of galaxies and in shaping the dynamics of their inter-stellar medium. However, the formation history of magnetic fields from initial seed-fields to well-ordered systems is not clear. Favoured s

Online Knowledge Integration for 3D Semantic Mapping: A Survey

Autor: Igelbrink, Felix, Renz, Marian, Günther, Martin, Powell, Piper, Niecksch, Lennart, Lima, Oscar, Atzmueller, Martin, Hertzberg, Joachim

Semantic mapping is a key component of robots operating in and interacting with objects in structured environments. Traditionally, geometric and knowledge representations within a semantic map have only been loosely integrated. However, recent advanc

We show that there exists an algorithm that takes as input two closed, simply connected, topological 4-manifolds and decides whether or not these 4-manifolds are homeomorphic. In particular, we explain in detail how closed, simply connected, topologi

Reconfigurable Acoustic Metalens with Tailored Structural Equilibria

Autor: Le, Dinh Hai, Kronowetter, Felix, Chiang, Yan Kei, Maeder, Marcus, Marburg, Steffen, Powell, David A.

The ability to concentrate sound energy with a tunable focal point is essential for a wide range of acoustic applications, offering precise control over the location and intensity of sound pressure maxima. However, conventional acoustic metalenses ar
