Semiquantum chaos

open access: yesPhysical Review Letters, 1994
We consider a system in which a classical oscillator is interacting with a purely quantum mechanical oscillator, described by the Lagrangian $ L = \frac{1}{2} \dot{x}^2 + \frac{1}{2} \dot{A}^2 - \frac{1}{2} ( m^2 + e^2 A^2) x^2 \>, $ where $A$ is a classical variable and $x$ is a quantum operator.

Conditions for order and chaos in the dynamics of a trapped Bose-Einstein condensate in coordinate and energy space

open access: yes, 2016
We investigate numerically conditions for order and chaos in the dynamics of an interacting Bose- Einstein condensate (BEC) confined by an external trap cut off by a hard-wall box potential. The BEC is stirred by a laser to induce excitations manifesting

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‐

The dynamics of living and thinking systems, biological networks, and the laws of physics

open access: yesDiscrete Dynamics in Nature and Society, 2004
Discrete chaotic dynamics (DCD) of living and thinking systems are presented in a form of networks of interacting agents with the abilities of energy and information exchange.

Quantum Chaos and Quantum Randomness - Paradigms of Entropy Production on the Smallest Scales

open access: yes, 2019
Quantum chaos is presented as a paradigm of information processing by dynamical systems at the bottom of the range of phase-space scales. Starting with a brief review of classical chaos as entropy flow from micro- to macro-scales, I argue that quantum ...

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

open access: yesAdvanced 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

Relativity and irreversibility

open access: yesDiscrete Dynamics in Nature and Society, 2004
The Lorentz transformation is extended to the decaying states in a relativistic model of interacting fields. The nonlocal action is defined beyond the Hilbert space.

Chaos and language

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2004
Human language is a complex communication system with unlimited expressibility. Children spontaneously develop a native language by exposure to linguistic data from their speech community. Over historical time, languages change dramatically and unpredictably by accumulation of small changes and by interaction with other languages.

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.
