The Uniform Isochronous Centers with Homogeneous Nonlinearities of Degree 6

Journal of Dynamical and Control Systems
In this paper we study the topological phase portraits of polynomial differential systems with a uniform isochronous center, whose nonlinear parts are homogeneous polynomials of degree 6. We obtain all the distinct topological phase portraits in the Poincaré disc. For each phase portrait, we give a precise system to realize it.

A Perspective of Multi‐Reflecting TOF MS

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Time‐of‐flight mass spectrometry (TOF MS) excels in rapid and high‐sensitivity analysis, making it a cornerstone of analytical chemistry. But as sample complexity explodes in omics studies, so does the need for higher resolving power to ensure accurate results.

Left Atrial Posterior Wall Functional Remodeling in Paroxysmal and Persistent Atrial Fibrillation. A Pilot Study

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background The left atrial posterior wall (LAPW) is often targeted in atrial fibrillation (AF) ablation due to its shared properties with pulmonary veins. However, substrate‐guided approaches using structural markers have shown inconsistent results.

Global phase portraits of quintic reversible uniform isochronous centers

Electronic Journal of Qualitative Theory of Differential Equations
This paper studies the global phase portraits of uniform isochronous quintic centers at the origin with time reversibility such that their nonlinear part is not homogeneous. By using Poincaré compactification, we obtain all possible phase portraits of this quintic polynomial differential system.

Words and Meters: Neural Evidence for a Connection Between Individual Differences in Statistical Learning and Rhythmic Ability in Infancy

Developmental Science, Volume 29, Issue 2, March 2026.
ABSTRACT Music and language are both hierarchically structured: syllables combine into words, and meters are groupings of musical beats. Statistical learning (SL) supports speech segmentation through computation of transitional probabilities between syllables, and individual differences in SL ability were found predictive of further language ...
