Remarks on the Myers-Perry and Einstein Gauss-Bonnet Rotating Solutions
The Kerr-type solutions of the five-dimensional Einstein and Einstein-Gauss-Bonnet equations look pretty similar when written in Kerr-Schild form. However the Myers-Perry spacetime is circular whereas the rotating solution of the Einstein-Gauss-Bonnet ...

Holonomy of Einstein Lorentzian manifolds [PDF]
The classification of all possible holonomy algebras of Einstein and vacuum Einstein Lorentzian manifolds is obtained. It is shown that each such algebra appears as the holonomy algebra of an Einstein (resp., vacuum Einstein) Lorentzian manifold, the direct constructions are given.

Quantum chemistry has been used to investigate the key factors that determine the (reverse) intersystem crossing processes in boron‐based organic light‐emitting diode emitters. The ortho‐linked through‐space charge‐transfer compounds exhibit smaller singlet–triplet splittings than their para‐linked through‐bond charge‐transfer regioisomers.

Rigidity of Weak Einstein-Randers Spaces [PDF]
The Randers metrics are popular metrics similar to the Riemannian metrics, frequently used in physical and geometric studies. The weak Einstein-Finsler metrics are a natural generalization of the Einstein-Finsler metrics.

Physics‐based inverse modeling of battery degradation with Bayesian methods
To further improve Lithium‐ion batteries (LiBs), a profound understanding of complex battery processes is crucial. Physical models offer understanding but are difficult to validate and parameterize. Therefore, automated machine‐learning methods (ML) are necessary to evaluate models with experimental data. Bayesian methods, e.g., Expectation Propagation

Excited State Branching Processes in a Ru(II)-Based Donor-Acceptor-Donor System. [PDF]
The photoinduced electron transfer processes in a Ru(II)‐based push–pull–push architecture which combines an inorganic and organic chromophore are elucidated in a joint spectroscopic‐theoretical approach. The applied design concept allows the excited state to be localized away from the metal onto the organic chromophore.

ABSTRACT The first patent to describe dielectrophoresis (DEP) as a means and process to separate particles from a mixture was granted by the US Patent Office to Henry Stafford Hatfield in 1924. The novel methods of sample preparation and designs of electrode geometry covered by the patent's disclosures and claims describe the basis for most present‐day

Einstein like -para Sasakian manifolds
Einstein like -para Sasakian manifolds are introduced. For an -para Sasakian manifold to be Einstein like, a necessary and sufficient condition in terms of its curvature tensor is obtained.

On Submanifolds of $N(k)$-Quasi Einstein Manifolds with a Type of Semi-Symmetric Metric Connection
In this study, we consider the $ N(k)- $quasi Einstein manifolds with respect to a type of semi-symmetric metric connection. We suppose that the generator of $ N(k)- $quasi-Einstein manifolds is parallel with respect to semi-symmetric metric connection
