Poisson convergence on the free Poisson algebra

open access: yes, 2015
Based on recent findings by Bourguin and Peccati, we give a fourth moment type condition for an element of a free Poisson chaos of arbitrary order to converge to a free (centered) Poisson distribution.

A Promising Point‐of‐Care Testing Strategy: Ultrasmooth Gold Nanogroove Arrays Biosensor Combined with Initial Rate Analysis

open access: yesAdvanced Science, EarlyView.
This work reports a nanoplasmonic biosensing platform with exceptional surface sensitivity (0.618 nm nm−1, Δn = 0.117 nmol) and narrow linewidth (≈20 nm) under normal incidence. By integrating a miscellaneous‐protein strategy with initial rate analysis (IRA), this sensor can detect 1 ng mL−1 of AFP in serum with a broad linear range (1–104 ng mL−1 ...

Chaos in Sandpile Models

open access: yes, 2010
We have investigated the "weak chaos" exponent to see if it can be considered as a classification parameter of different sandpile models. Simulation results show that "weak chaos" exponent may be one of the characteristic exponents of the attractor of ...

PCSK9 Loss‐of‐Function Disrupts Cellular Microfilament Network via LIN28A/HES5/JMY Axis in Neural Tube Defects

open access: yesAdvanced Science, EarlyView.
PCSK9 acts as a molecular chaperone promoting LIN28A lysosomal degradation. LIN28A elevates transcription factor HES5, increasing JMY expression. PCSK9 loss causes neural tube defects (NTDs) by disrupting the LIN28A/HES5/JMY axis, and high JMY disorganizes the neural progenitor cell microfilament network, leading to incomplete neural tube structure in ...

Chaos and Synchronized Chaos in an Earthquake Model

open access: yes, 1998
We show that chaos is present in the symmetric two-block Burridge-Knopoff model for earthquakes. This is in contrast with previous numerical studies, but in agreement with experimental results. In this system, we have found a rich dynamical behavior with

Movement Mechanisms Harness Lévy Flight for Energy‐Efficient Wastewater Treatment in Microalgae–Bacteria Systems

open access: yesAdvanced Science, EarlyView.
Here, our novel model that integrates metabolism with motility dynamics reveals that microalgae shift bacterial movement toward Lévy flight patterns, enhancing encounter rates and self‐aggregation. This microecological manipulation reduces energy costs, strengthens functions such as pollutant removal and system stability.

A simple method for detecting chaos in nature

open access: yes, 2020
Chaos, or exponential sensitivity to small perturbations, appears everywhere in nature. Moreover, chaos is predicted to play diverse functional roles in living systems.

Localization and the effects of symmetries in the thermalization properties of one-dimensional quantum systems

open access: yes, 2013
We study how the proximity to an integrable point or to localization as one approaches the atomic limit, as well as the mixing of symmetries in the chaotic domain, may affect the onset of thermalization in finite one-dimensional systems.

Nonlinear Dynamic Characteristics and Optimal Control of SMA Composite Wings Subjected to Stochastic Excitation

open access: yesShock and Vibration, 2015
A kind of high-aspect-ratio shape memory alloy (SMA) composite wing is proposed to reduce the wing’s fluttering. The nonlinear dynamic characteristics and optimal control of the SMA composite wings subjected to in-plane stochastic excitation are ...
