A two-dimensional non-equilibrium dynamic model [PDF]
, 2007 This paper develops a non-equilibrium dynamic model (NEDyM) with Keynesian features (it allows for a disequilibrium between output and demand and it considers a constant marginal propensity to consume), but where production is undertaken under plain ...

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2814-2827, May 2026.ABSTRACT Purpose 3D free‐breathing, proton, contrast‐agent‐free MR methods are increasingly used for pulmonary ventilation‐weighted measurements. The methods are split between: (1) signal‐based, which rely on lung parenchyma signal changes during respiration, and (2) volume‐based that utilize the Jacobian determinant of deformation fields from the ...

Accelerating PREFUL MRI: Comparison of Registration Methods and Impact of Time Series Reduction
NMR in Biomedicine, Volume 39, Issue 5, May 2026.Retrospective shortening of the PREFUL MRI acquisition showed that most parameters remained strongly correlated (≥ 77%) and regionally concordant (overlap ≥ 79%) with the 55‐s ground truth down to 30 s in healthy volunteers and COPD, except for perfusion, which was more sensitive to truncation.

Bifurcation phenomena in magnetically confined toroidal plasmas
Advances in Physics: X, 2020 Bifurcation phenomena observed in turbulence and transport, in topology of magnetic field and MHD, and the interplay between turbulence and MHD bifurcation in magnetically confined toroidal plasmas are reviewed.

Ligand‐driven modulation of chaperone–cochaperone networks shapes proteostasis outcomes
Protein Science, Volume 35, Issue 5, May 2026.Abstract Protein homeostasis depends on a delicate interplay between folding and degradation, orchestrated by molecular chaperones. Among them, Hsp90 is a central hub, regulating nearly 10% of the proteome through ATP‐driven conformational cycles and selective interactions with cochaperones.

Bifurcation of a heterodimensional cycle with weak inclination flip
Discrete & Continuous Dynamical Systems - B, 2012 Local moving frame is constructed to analyze the bifurcation of a heterodimensional cycle with weak inclination flip in $\mathbb{R}^4$. Under some generic hypotheses, the existence conditions for the heteroclinic orbit, $1$-homoclinic orbit, $1$-periodic orbit and two-fold or three-fold $1$-periodic orbit are given, respectively.

Discrete Dynamics in Nature and Society, 2016 The Allee effect is incorporated into a predator-prey model with linear functional response. Compared with the predator-prey which only takes the crowding effect and predator partially dependent on prey into consideration, it is found that the Allee ...

Complex Dynamics in Generalized Hénon Map
Discrete Dynamics in Nature and Society, 2015 The complex dynamics of generalized Hénon map with nonconstant Jacobian determinant are investigated. The conditions of existence for fold bifurcation, flip bifurcation, and Hopf bifurcation are derived by using center manifold theorem and bifurcation ...
