Eigenvalue Problem Describing Magnetorotational Instability in Outer Regions of Galaxies

open access: yesMathematics
The existence of magnetic fields in spiral galaxies is beyond doubt and is confirmed by both observational data and theoretical models. Their generation occurs due to the dynamo mechanism action associated with the properties of turbulence.

Structural and Optical Characterization of Pure and Lanthanum Substituted Nd1–xLaxAlO3 Prepared by Sol–Gel Method

open access: yesChemistryOpen, EarlyView.
The variations in crystal‐field splitting parameter Δ for the pure and elongated polyhedra. The present studies offer the new methodology to tune crystal‐field energy by means of lattice distortion. The present results are useful for fine tuning of laser energy.

Modeling General Asymptotic Calabi–Yau Periods

open access: yesFortschritte der Physik, EarlyView.
Abstract In the quest to uncovering the fundamental structures that underlie some of the asymptotic Swampland conjectures the authors initiate the general study of asymptotic period vectors of Calabi–Yau manifolds. The strategy is to exploit the constraints imposed by completeness, symmetry, and positivity, which are formalized in asymptotic Hodge ...

Unification of Conformal and Fuzzy Gravities With Internal Interactions Resulting in SO(10) and a Possible Probe Through Stochastic Gravitational Wave Background

open access: yesFortschritte der Physik, EarlyView.
Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.

Finite and continuous perturbations of matrix eigenvalues

open access: yesApplied Mathematics Letters, 1998
AbstractAn elementary proof is given that some well-known formulae for derivatives of eigenvalues of matrix-valued functions hold under weaker hypotheses than are required by the usual proofs. The relationship between continuous and finite perturbations is also discussed.

Continuous‐Time Markov Population PK/PD Modeling of Longitudinal EASI Categorical Score in Atopic Dermatitis Treated With Rocatinlimab, an Anti‐OX40 Monoclonal Antibody

open access: yesCPT: Pharmacometrics &Systems Pharmacology, EarlyView.
ABSTRACT Rocatinlimab (AMG 451/KHK4083) is a potential T‐cell rebalancing therapy that inhibits and reduces the number of pathogenic T cells by targeting the OX40 receptor; it is associated with a progressive and sustained response for patients with moderate‐to‐severe atopic dermatitis (AD).

Corrections of Electron–Phonon Coupling for Second‐Order Structural Phase Transitions

open access: yesphysica status solidi (b), EarlyView.
The left image illustrates a weak electron–phonon coupling, while the right image depicts a strong electron–phonon coupling. The weak electron–phonon coupling interaction between the lattice and electrons is susceptible to destabilization by an increase in temperature.
