As the LHC beams cannot be polarized, introducing a dense polarized gas target at the LHCb experiment at CERN, to be operated concurrently with beam-beam collisions, will facilitate fixed-target interactions to explore a new energy regime of spin physics measurements. Unfortunately, typical surface coatings used to avoid polarization losses, such as water, Teflon, or aluminum, are prohibited due to restrictions imposed by vacuum and beam policies. [...]

Understanding information propagation and computational capabilities in large-scale brain models is crucial for advancing both neuroscience and neuro-inspired computing. It remains unknown how complexity affects the performance of simulated biological networks in predicting non-linear dynamics. [...]

The rapid development of new imaging technologies across scientific domains–especially high-throughput technologies–results in a growing volume of image datasets in the Tera- to Petabyte scale. Efficient visualization and analysis of such massive image resources is critical but remains challenging due to the sheer size of the data, its continuous growth, and the limitations of conventional software tools to address these problems.

Proton exchange membrane (PEM) electrolysis is a promising process for sustainable hydrogen production, but its commercialization is delayed by high costs and elusive degradation of membrane electrode assemblies (MEAs) [1]. In operando Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI) offer the potential to investigate degradation mechanisms during electrolysis, and thus, provide highly relevant insights for enhanced performance [2,3].In a first part of this contribution, a custom-designed miniature PEM electrolysis cell is presented, fitting the spatial constraints of a 1H coil of a commercially available imaging probe.

Over the past 15 years, GPR full-waveform inversion (FWI) has shown high potential in a wide range of applications. Since most of these studies have been applied in the computationally attractive 2D environment, limitations emerge with respect to antenna modeling and wave propagation effects, consequently leading to errors in the reconstructed parameters. [...]

The Debye-Hückel (DH) theory, a cornerstone in modeling ionic activities in electrolytes for over a century, remains widely applied like in equations of state and Onsager’s conductivity theory1. In the DH theory, the distribution of ions around a central ion is calculated assuming electrostatic interactions of point charges that are dispersed in a dielectric continuum2 [...]

Crystalline materials, such as metals and semiconductors, nearly always contain a special defect type called dislocation. This defect decisively determines many important material properties, e.g., strength, fracture toughness, or ductility. [...]
