A combinatorial proof that Schubert vs. Schur coefficients are nonnegative [PDF]

, 2014
We give a combinatorial proof that the product of a Schubert polynomial by a Schur polynomial is a nonnegative sum of Schubert polynomials. Our proof uses Assaf's theory of dual equivalence to show that a quasisymmetric function of Bergeron and Sottile ...

Effect of Horizontal Resolution on a Meso‐β‐Scale Vortex Simulation in an Extreme Rainstorm on 22 May 2020 Over South China: A Contrastive Study Based on Different‐Resolution Ensembles

Earth and Space Science, Volume 11, Issue 1, January 2024.
Abstract A transient extreme rainstorm that occurred over Guangzhou city, China, on 22 May 2020, has been investigated based on two ensemble prediction systems (EPSs), one with 9‐km (TRAMS9km‐EPS) and the other with 3‐km (TRAMS3km‐EPS) grid spacings, respectively.

An Unsupervised Deep Learning Framework for Retrospective Gating of Catheter‐Based Cardiac Imaging

IET Signal Processing, Volume 2024, Issue 1, 2024.
Motion artifacts are a major challenge in the in vivo application of catheter‐based cardiac imaging modalities. Gating is a critical tool for suppressing motion artifacts. Electrocardiogram (ECG) gating requires a trigger device or synchronous ECG recordings for retrospective analysis.

Polygonal Quasiconformality and Grunsky’s Operator

Axioms
This paper concerns the old problem of the connection between the dilatations of a given quasisymmetric homeomorphism h of a circle and the associated polygonal quasiconformal maps with a fixed finite number of boundary points, namely whether k(h)=supkn,
