The generic unfolding of a codimension-two connection to a two-fold singularity of planar Filippov systems

open access: yes, 2017
Generic bifurcation theory was classically well developed for smooth differential systems, establishing results for $k$-parameter families of planar vector fields.

Nonequilibrium Period with Emergence of Marangoni Circulations in Meniscus Splitting

open access: yesAdvanced Materials Interfaces, EarlyView.
The emergence and evolution of Marangoni convection in the meniscus splitting phenomenon are investigated. During the mass circulation of viscous fluids, the confluence and bifurcation of polymer dispersions beneath the evaporative interface lead to the inhomogeneous densification of the skin layer.

Clustering, Chaos and Crisis in a Bailout Embedding Map

open access: yes, 2007
We study the dynamics of inertial particles in two dimensional incompressible flows. The particle dynamics is modelled by four dimensional dissipative bailout embedding maps of the base flow which is represented by 2-d area preserving maps.

A Sleeve Alters the Pressure‐Stretch Curve of a Hyperelastic Balloon to Enable Pre‐Programmed Sequencing

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...

Streamline topology and dilute particle dynamics in a Karman vortex street flow

open access: yes, 2003
Three types of streamline topology in a Karman vortex street flow are shown under the variation of spatial parameters. For the motion of dilute particles in the K\'arm\'an vortex street flow, there exist a route of bifurcation to a chaotic orbit and more

Fabrication Technologies for Soft, Multimaterial Optical Fibers for In Vivo Diagnostics and Phototherapy, With a Focus on Extrusion Printing

open access: yesAdvanced Materials Technologies, EarlyView.
Soft multimaterial optical fibers integrate multiple functionalities—such as waveguiding, side emission, sensing, drug delivery or actuation—into a single filament for wearable, implantable, and tissue‐integrated devices for diagnostics and phototherapy.

Some results on the dynamics generated by the Bazykin model

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2006
A predator-prey model formerly proposed by A. Bazykin et al. [Bifurcation diagrams of planar dynamical systems (1985)] is analyzed in the case when two of the four parameters are kept fixed.

Dynamic bifurcation for the granulation convection in the solar photosphere

open access: yesBoundary Value Problems, 2017
The main objective of this paper is to investigate the dynamic bifurcation for the granulation convection in the solar photosphere. Based on the dynamic bifurcation theory, which is established by Ma and Wang (Phase transition dynamics, pp. 380-459, 2014)

Directed Navigation of Magnetotactic Bacteria via Magnetotaxis in a 3D Vasculature‐On‐A‐Chip

open access: yesAdvanced Materials Technologies, EarlyView.
A perfusable vascular network is developed to investigate MTB at the single‐microorganism level. MTB is demonstrated to successfully align and navigate along the magnetic field inside the microvessels. Abstract Magnetotactic bacteria (MTB), inherently motile and self‐powered, are promising biorobotic candidates for targeted anti‐cancer drug delivery ...
