Low-Intensity Pulsed Ultrasound Stimulation Modulates the Nonlinear Dynamics of Local Field Potentials in Temporal Lobe Epilepsy

open access: yesFrontiers in Neuroscience, 2019
Low-intensity pulsed ultrasound stimulation (LIPUS) can inhibit seizures associated with temporal lobe epilepsy (TLE), which is the most common epileptic syndrome in adults and accounts for more than half of the cases of intractable epilepsy ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Time-shift multiscale entropy analysis of physiological signals

open access: yes, 2017
Measures of predictability in physiological signals using entropy measures have been widely applied in many areas of research. Multiscale entropy expresses different levels of either approximate entropy or sample entropy by means of multiple factors for ...

Fault Diagnosis of the Bearing based on the Wavelet Transform and Approximate Entropy

open access: yesJixie chuandong, 2015
Combining the wavelet transform and approximate entropy theory,according to the characteristic that the approximate entropy will become larger with the increase of signal complexity,it is applied to the analysis of acoustic emission signals of the ...

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

近似熵在欠驱动五杆机构混沌边缘分析中的应用

open access: yesJixie chuandong, 2014
Entropy is an approach to measure the irregularity of a set of data and one of rare quantitative analysis indicators for chaos.By using the method of entropy the edge of chaos for a mechanism is found and the threshold for the calculation of approximate ...

Quaternion Entropy for Analysis of Gait Data

open access: yesEntropy, 2019
Nonlinear dynamical analysis is a powerful approach to understanding biological systems. One of the most used metrics of system complexities is the Kolmogorov entropy. Long input signals without noise are required for the calculation, which are very hard

Fractional Cumulative Residual Mean Relative Entropy and Its Application in an Aeroengine Gas Path System

open access: yesFractal and Fractional, 2023
Mean relative entropy has a wide range of applications in measuring information differences. However, relative entropy is difficult to approximate from empirical distribution entropy.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
