ABSTRACT This paper develops a mathematical framework for interpreting observations of solar inertial waves in an idealized setting. Under the assumption of purely toroidal linear waves on the sphere, the stream function of the flow satisfies a fourth‐order scalar equation.

LowCOST‐HSQC Variants for Fast‐Pulsing High ω1$$ {\omega}_1 $$‐Resolved 2D Experiments
The LowCOST‐HSQC is a sensitivity‐enhanced HSQC version that retains unused proton polarization for subsequent scans in correlations to low natural abundance nuclei like 13$$ {}^{13} $$C or 15$$ {}^{15} $$N. Together with fast polarization distribution via isotropic mixing, it allows the acquisition of fast‐pulsing 2D experiments.

Vibration Attenuation of Cantilever Beam Using Electromagnetic Delayed Feedback
ABSTRACT This study presents a combined analytical and numerical investigation of a single‐input single‐output delayed feedback controller designed to suppress vibrations in a cantilever beam actuated by an electromagnet positioned beneath its free end. An analytical model was developed using the linearized equation of motion for a transversely excited

ABSTRACT Numerical simulation of hydraulic fracturing remains challenging due to the strong coupling between geomechanics and fluid flow when modelling multiple physical mechanisms of rock deformation, fracture evolution and fluid leak‐off. This study develops a coupled hydraulic fracture propagation framework that combines the extended finite element ...

Bilinear Differential Forms and the Loewner Framework for Rational Interpolation [PDF]
The Loewner approach, based on the factorization of a special-structure matrix derived from data generated by a dynamical system, has been applied successfully to realization theory, generalized interpolation, and model reduction. We examine some connections between such approach and that based on bilinear- and quadratic differential forms arising in ...

Greater future range expansions in alien than native ant species
There is growing concern that many species may not be able to track suitable conditions under climate change and suffer range contractions as a result. At the same time, alien species introduced to novel geographic ranges are often assumed to benefit from climate change.

Interpolation of bilinear operators between Banach function spaces
We study bilinear operators between couples of Banach function spaces with the second coordinate $L_\infty$-space. We show an estimate in terms of the $K$-functional.

Wilting wildflowers and bummed‐out bees: Climate change threatens US state symbols
Abstract Species designated as state symbols in the United States carry cultural importance, embody historical heritage and maintain long‐standing linkages to Indigenous traditions. However, they are threatened by climate change and even face the risk of local or global extinction.
