Ionization via Chaos Assisted Tunneling

, 1997
A simple example of quantum transport in a classically chaotic system is studied. It consists in a single state lying on a regular island (a stable primary resonance island) which may tunnel into a chaotic sea and further escape to infinity via chaotic ...

Spatiotemporal Reservoir Computing with a Reconfigurable Multifunctional Memristor Array

Advanced Materials, EarlyView.
This study presents a hardware physical reservoir computing system using a tri‐modal memristive crossbar array. Stochastic masking, bistable nonlinear activation, and analog readout enable fully in‐memory spatiotemporal processing. Demonstrations on cellular automata, Lorenz prediction, ADHD EEG classification, and chaotic KS modeling highlight its ...

Stickiness in mushroom billiards

, 2005
We investigate dynamical properties of chaotic trajectories in mushroom billiards. These billiards present a well-defined simple border between a single regular region and a single chaotic component.

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 Orbits in Thermal-Equilibrium Beams: Existence and Dynamical Implications

, 2003
Phase mixing of chaotic orbits exponentially distributes these orbits through their accessible phase space. This phenomenon, commonly called ``chaotic mixing'', stands in marked contrast to phase mixing of regular orbits which proceeds as a power law in ...

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

Image encryption based on s-box and 3D-chaotic maps and secure image transmission through ofdm in rayleigh fading channel [PDF]

Engineering and Technology Journal
Data security is vital if transferred over a wireless network or stored on a personal computer. The essential properties of chaos, such as initial state sensitivity and unpredictability, make it a crucial candidate for encryption applications. This paper
