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

open access: yesAdvanced 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‐

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

open access: yesMathematics
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.

Global stability, limit cycles and chaotic behaviors of second order interpolative sigma delta modulators [PDF]

open access: yes, 2011
It is well known that second order lowpass interpolative sigma delta modulators (SDMs) may suffer from instability and limit cycle problems when the magnitudes of the input signals are at large and at intermediate levels, respectively.

Entropy, chaos and excited-state quantum phase transitions in the Dicke model [PDF]

open access: yes, 2016
We study non-equilibrium processes in an isolated quantum system ---the Dicke model--- focusing on the role played by the transition from integrability to chaos and the presence of excited-state quantum phase transitions.

A Review on Microreactor Design for Effective Fischer–Tropsch Process Intensification

open access: yesAdvanced Materials Technologies, EarlyView.
Design strategies for effective Fischer–Tropsch process intensification are summarized based on experimental and simulation experiences. Recommendations for catalyst loading of packed‐bed and wash‐coated microchannel, microtube, micromonolith, and microstructured reactors are discussed.

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

open access: yesComputational 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.

Chaos and hidden chaos in a 4D dynamical system using the fractal-fractional operators

open access: yesAIMS Mathematics
Although fractional calculus is about three centuries old, it has become the key to understanding many complex real-world phenomena. During the past few decades, many fractional derivatives have appeared. Among these, the fractal-fractional derivatives have shown acceptance in describing some real-world problems.
