Manifolds in the Medial Premotor Cortex During Switching From Attending to Tapping to a Metronome
Annals of the New York Academy of Sciences, Volume 1558, Issue 1, April 2026.Low‐dimensional manifolds emerged in neural populations of the medial premotor cortex of macaque monkeys while they performed an attend‐then‐synchronize tapping task with periodic visual stimuli. The neural dynamics followed an increasingly oscillatory trajectory from attending to tapping stages of the trial (left panel).

Microvascular Health as a Key Determinant of Organismal Aging
Advanced Science, Volume 12, Issue 47, December 18, 2025.Abstract Aging is a complex, multifaceted process affecting all organ systems, with vascular aging playing a central role in organismal health decline. Beyond its role in circulation, the vascular system acts as a dynamic interface between tissues, influencing countless physiological functions such as tissue regeneration and repair, immune responses ...

From isochronous potentials to isochronous systems
Journal of Differential Equations, 2015 This paper studies Hamiltonian systems of the type \[ \left\{ \begin{align*}{ \dot{y}&= - V'(x) \cr \dot{x}&= T'(y) ,}\end{align*} \right. \] where \(T\) and \(V\) are \(C^2\)-functions, with associated Hamiltonian function \[ E(x,y) = T(y) + V(x). \] The system is assumed to have a center at a certain point \((x_0,y_0)\), and \(V(x_0) = T(y_0) = 0 ...

Aging Cell, Volume 24, Issue 10, October 2025.Although the ribs are the only human bones capable of regenerating large‐scale defects, this remarkable ability declines with skeletal maturity and age. Here, we reproduce skeletal maturity and age‐related phenotypic changes in a mouse model of rib resection.

Bifurcation of critical periods of a quintic system
Electronic Journal of Differential Equations, 2018 We investigate the critical period bifurcations of the system $$ \dot x = ix + x \bar x ( a x^3 + b x^2 \bar x + \bar x \bar x^2+d \bar x^3) $$ studied in [6].

Journal of Quaternary Science, Volume 40, Issue 5, Page 831-846, July 2025.ABSTRACT The high mountains of Taiwan provide a unique location for Quaternary palaeoclimate research in East Asia and the north‐western Pacific. This study applies geomorphological field mapping and rock surface exposure dating with paired (10Be/26Al) in situ‐produced terrestrial cosmogenic nuclides to identify and date glacial landforms and boulders ...
