The Journal of Physiology, EarlyView.Abstract figure legend Schematic overview of the experimental and computational framework for investigating hiPSC‐CM electrophysiology with MEA systems. The MEA‐based model integrates experimental data with phenotype‐specific ionic models and tissue‐level heterogeneity.

Critical Periods of Perturbations of Reversible Rigidly Isochronous Centers [PDF]
Abstract and Applied Analysis, 2013 We study the problem of bifurcation of critical periods of a time-reversible polynomial system of degreen. We first present a new method to find the number of zeros of the period function. Then applying our results, we study the number of critical periods for some polynomial systems and obtain new results.

Medical Physics, Volume 53, Issue 8, August 2026.Abstract Background The clinical translation of Minibeam RT (MBRT) has recently started thanks to the first human treatments recently performed. However, despite experimental evidence, the impact of the dose distribution parameters involved on the magnitude of the effect itself and the underlying radiobiological mechanisms are still only partially ...

Lighting up FLASH and beyond: TLD response across four orders of magnitude in proton dose rate
Medical Physics, Volume 53, Issue 8, August 2026.ABSTRACT Background Thermoluminescent dosimeters (TLDs) are widely used for proton therapy dosimetry and remote audits. Yet their response under pulsed delivery and the ultrahigh dose rates relevant to proton FLASH remains incompletely characterized.

Differentiation of Plant and Animal‐Derived Cholesterol Using irm‐13C NMR and IRMS
Magnetic Resonance in Chemistry, Volume 64, Issue 8, Page 701-708, August 2026.Determining and certifying the origin of ingredients, starting materials, and excipients used in manufactured goods like cosmetics and medicines can be difficult. In this report, we describe a robust approach for identifying the origin of cholesterol, a component of myriad consumer products using irm‐13C NMR and IRMS to differentiate plant versus ...

Rhythmic Structure Shapes Dyadic Self−Other Representations Through Interpersonal Action Coupling
Annals of the New York Academy of Sciences, Volume 1562, Issue 1, August 2026.Musical rhythms can imply multiple interpretations of the beat, allowing various ways of moving together. Dyads drummed to songs, producing rhythmic ratios varying the relative temporal complexity of their movements. Stable coordination increased social bonding, which decreased with complexity.

Bifurcation of limit cycles from quartic isochronous systems
Electronic Journal of Differential Equations, 2014 This article concerns the bifurcation of limit cycles for a quartic system with an isochronous center. By using the averaging theory, it shows that under any small quartic homogeneous perturbations, at most two limit cycles bifurcate from the period ...

Annals of the New York Academy of Sciences, Volume 1562, Issue 1, August 2026.We adapted the FREQ‐NESS pipeline to event‐related MEG data from 140 adults during a melody‐recognition task, revealing an age‐related reorganization of frequency‐specific brain networks. Younger adults showed task‐related reduction in the prominence of alpha networks, whereas older adults maintained prominent slower alpha networks (8.6–10.0 Hz) across

Isochronous centers of Lienard type equations and applications
Journal of Mathematical Analysis and Applications, 2007 In this work we study the equation $(E) \ddot x + f(x) \dot x^2 + g(x) = 0$ with a center at 0 and investigate conditions of its isochronicity. When $f$ and $g$ are analytic (not necessary odd) a necessary and sufficient condition for the isochronicity of 0 is given. This approach allows us to present an algorithm for obtained conditions for a point of
