Investigation of Stray‐Light Patterns in the eROSITA X‐Ray Cameras

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT eROSITA (extended ROentgen Survey with an Imaging Telescope Array) is the soft X‐ray instrument aboard the Spectrum‐Roentgen‐Gamma (SRG) mission, developed under the responsibility of the Max Planck Institute for Extraterrestrial Physics (MPE).

Diffusion Coefficient and Viscosity of Methyl Viologen Electrolyte Estimation Based on a Kinetic Monte Carlo Computational Approach Coupled with the Mean Square Displacement Method

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
A novel and comprehensive 3D‐resolved kinetic Monte Carlo model coupled with mean square displacement analysis is introduced. This computational approach allows to explore, for the first time, the concentration and the state of charge effects on ionic diffusion coefficient and viscosity in methyl viologen‐based electrolytes used in organic redox flow ...

Construction of an A-manifold on a principal torus bundle

open access: yesAnnales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2013
We construct a new example of an A-manifold, i.e. a Riemannian manifold with cyclic-parallel Ricci tensor. This condition can be viewed as a generalization of the Einstein condition.

Optimization of 3D‐Printed Structured Packings—Current State and Future Developments

open access: yesChemie Ingenieur Technik, EarlyView.
This paper gives an overview about structured packing development for distillation, surveying heuristic development cycles, computational fluid dynamics simulations, and additive manufacturing techniques. The emerging application of shape optimization to improve packings is emphasized, and its benefits, impact, and limitations are discussed.

High atmospheric pressure rescues plant growth under humidity stress: A model for climate‐resilient deep underground agriculture

open access: yesDeep Underground Science and Engineering, EarlyView.
High atmospheric pressure (120 kPa) in deep underground counteracts humidity‐induced physiological stress in plants, stabilizing water balance and enhancing antioxidative defenses. This synergy boosts biomass despite elevated humidity, demonstrating sustainable deep underground agriculture potential under climate uncertainty.

The Impact of Quasi-Conformal Curvature Tensor on Warped Product Manifolds

open access: yesAxioms
This work investigates the effects on the factor manifolds of a singly warped product manifold resulting from the presence of a quasi-conformally flat, quasi-conformally symmetric, or divergence-free quasi-conformal curvature tensor.

EEG CONNECT: A proposed reporting checklist for EEG‐based connectivity studies in clinical epilepsy research

open access: yesEpilepsia Open, EarlyView.
Abstract EEG‐based connectivity analysis has emerged as a promising approach for investigating brain network dynamics in clinical epilepsy research. However, the diversity of analytical approaches, preprocessing pipelines, and reporting practices poses challenges to reproducibility and clinical translation.

Characterization on N(k)-Mixed Quasi-Einstein Manifold

open access: yes, 2019
[[abstract]]In the present paper we study characterizations of odd and even dimensional N(k)-mixed quasi-Einstein manifold and finally prove that a N(k)-mixed quasi-Einstein manifold is a semi mixed quasi- Einstein manifold under a certain condi ...
