From Folding Mechanics to Robotic Function: A Unified Modeling Framework for Compliant Origami. [PDF]
Adv Sci (Weinh)A geometry‐consistent DDG framework captures compliant origami deformation from rigid‐like folding to soft panel bending. By tuning crease and panel stiffness, bistable snap‐through responses transform into smooth monostable deformation, enabling programmable stability and robot‐scale locomotion.

Bifurcated Hydrogen Bonds and the Fold Switching of Lymphotactin [PDF]
The Journal of Physical Chemistry B, 2020 Abstract Lymphotactin (Ltn) exists under physiological conditions in an equilibrium between two interconverting structures with distinct biological functions. Using Replica-Exchange-with-Tunneling we study the conversion between the two folds.

On the Double-Zero Bifurcation of Jerk Systems
Mathematics, 2023 In this paper, we construct approximate normal forms of the double-zero bifurcation for a two-parameter jerk system exhibiting a non-degenerate fold bifurcation.

Fold bifurcation of T-singularities and invariant manifolds in 3D piecewise-smooth dynamical systems
, 2020 One of the most interesting typical singularity observed in 3D piecewise-smooth dynamical systems is the so called T-singularity (Teixeira Singularity).

Control-based continuation of unstable periodic orbits [PDF]
, 2009 Copyright © 2010 American Society of Mechanical Engineers (ASME)We present an experimental procedure to track periodic orbits through a fold (saddle-node) bifurcation and demonstrate it with a parametrically excited pendulum experiment where the tracking

Arnol′d tongues arising from a grazing-sliding bifurcation [PDF]
, 2009 The Neımark–Sacker bifurcation, or Hopf bifurcation for maps, is a well-known bifurcation for smooth dynamical systems. At this bifurcation a periodic orbit loses stability, and, except at certain “strong” resonances, an invariant torus is born.

Fast-Slow Coupling Dynamics Behavior of the van der Pol-Rayleigh System
Mathematics, 2021 In this paper, the dynamic behavior of the van der Pol-Rayleigh system is studied by using the fast–slow analysis method and the transformation phase portrait method.

Analysis of the Neuron Dynamics in Thalamic Reticular Nucleus by a Reduced Model
Frontiers in Computational Neuroscience, 2021 Strategically located between the thalamus and the cortex, the inhibitory thalamic reticular nucleus (TRN) is a hub to regulate selective attention during wakefulness and control the thalamic and cortical oscillations during sleep.

The two-fold singularity of nonsmooth flows:Leading order dynamics in n-dimensions [PDF]
, 2013 A discontinuity in a system of ordinary differential equations can create allow that slides along the discontinuity locus. Prior to sliding, the flow may have collapsed onto the discontinuity, making the reverse flow non-unique, as happens when dry ...
