Complex Characteristics and Control of Output Game in Cross-Border Supply Chains: A Perspective of Inter-Chain Competition

Mathematics
In this paper, an output dynamic game model of intertwined supply chains operating in two different countries is established. The Nash equilibrium point of the model and its stable region are obtained using nonlinear dynamic principles.

Deterministic chaos in an ytterbium-doped mode-locked fiber laser. [PDF]

Optics Express, 2018
We experimentally study the nonlinear dynamics of a femtosecond ytterbium doped mode-locked fiber laser. With the laser operating in the pulsed regime a route to chaos is presented, starting from stable mode-locking, period two, period four, chaos and ...

Neuroimmune Microenvironment Reprogramming via Immuno‐piezoelectric Transducers for Synergistic Stem Cell Therapy in Traumatic Brain Injury

Advanced Materials, EarlyView.
A novel immuno‐piezoelectric transducer is innovatively developed. This device promotes neural stem cell (NSC) differentiation and maturation via ultrasound‐induced electrical stimulation and it amplifies the therapeutic efficacy of NSC in traumatic brain injury (TBI) by modulating the immune microenvironment. This piezoelectric transducer with “immune‐

Chaotic dynamics in a discrete-time predator-prey food chain [PDF]

Computational Ecology and Software, 2015
In this paper, we consider a classical discrete-time food chain model describing predators-prey interaction. The Holling type I functional response is used as the uptake for both predators.

Transparent, Sprayable Plastic Films for Luminescent Down‐Shifted‐Assisted Plant Growth

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
Spreading the light: A modular approach to down‐shifting europium‐containing polyoxotitanium luminescent cages is developed, allowing their incorporation into sprayable plastic coatings on agricultural greenhouses for accelerated plant growth. Abstract The world's steadily growing population and global heating due to climate change are a threat to food

Printability Metrics in Direct Ink Writing: Critical Review of the Literature and Novel Perspective Based on Dimensional Analysis

Advanced Materials Technologies, EarlyView.
The impossibility of defining universal printability criteria for Direct Ink Writing (DIW) requires “unpacking” the process into printing subfunctions. Each of these is rationalized by identifying dimensionless groups, allowing effective comparison between the various material‐ and process‐related parameters for printability purposes.

Covert Binary Communications through the Application of Chaos Theory: Three Novel Approaches [PDF]

Journal of Systemics, Cybernetics and Informatics, 2008
Today, most covert communications systems use a spreadspectrum approach to ensure that transmissions remain clandestine. This paper expands beyond traditional spreadspectrum schemes and into chaos theory in communications by presenting a novel design for
