The η-Einstein condition on indefinite S-manifolds
Mathematica Slovaca, 2014 Abstract An η-Einstein condition is introduced in the context of indefinite globally framed f-manifolds, and several Schur-type results for indefinite S-manifolds are proved.

Magnetic Resonance in Medicine, Volume 93, Issue 5, Page 2020-2028, May 2025.Abstract Purpose To characterize the diffusion time (Δeff) dependence of apparent diffusion coefficient (ADC) and intravoxel incoherent motion–related parameters in the human kidney at 3 T. Methods Sixteen healthy volunteers underwent an MRI examination at 3 T including diffusion‐weighted imaging at different Δeff ranging from 24.1 to 104.1 ms.

Lessons Learned on Obtaining Reliable Dynamic Properties for Ionic Liquids
ChemPhysChem, Volume 26, Issue 8, April 14, 2025.The performance of different force fields in the calculation of transport properties of ionic liquids is studied at the example of [C2C1Im][NTf2]. Qualitatively, all investigated force field formulations yield accurate results, but to achieve quantitative agreement to reference data, either explicit polarization or a refinement of the classical Lennard‐

Three-dimensional Riemannian manifolds associated with locally conformal Riemannian product manifolds [PDF]
arXivA 3-dimensional Riemannian manifold equipped with a tensor structure of type $(1,1)$, whose fourth power is the identity, is considered. This structure acts as an isometry with respect to the metric. A Riemannian almost product manifold associated with such a manifold is also studied.

Acoustic Rayleigh Wave Turbulence in Soft Viscoelastic Matter
Advanced Science, Volume 12, Issue 15, April 17, 2025.Discrete acoustic Rayleigh wave turbulence (DARWT) is observed on the free surface of viscoelastic materials under monochromatic excitation. Governed by bulk shear rigidity supporting inertial modes against surface tension, the nonlinear Rayleigh waves exhibit distinct power‐law scaling and turbulence features in their Kolmogorov–Zakharov spectra. This

Variable‐Range Hopping Conduction in Amorphous, Non‐Stoichiometric Gallium Oxide
Advanced Electronic Materials, Volume 11, Issue 4, April 2025.The combination of experimental evidence, ab‐initio DOS calculations and quantitative modeling by kinetic Monte Carlo simulations reveals: Variable‐range hopping (VRH) is the dominant electron conduction mechanism in a‐GaOx (x = 0.8 to 1.0), even at room temperature, which leads to a new, fundamental understanding of a‐GaOx‐based electronic devices ...
