Profiling Co‐Occurrent Morphological Phenotypes and Their Degree of Expression Severity in Vacuolated Cells by Holo‐Tomographic Flow Cytometry and Fractal Analysis

Advanced Intelligent Systems, EarlyView.
HTFC gets 3D refractive index tomograms of flowing cells. Label‐free monocytes are engineered to express patterns of cytoplasmic vacuoles. From the tomogram, an efficient dimensionality reduction is operated. Interpretable features are extracted to classify the expression severity of phenotypes coexisting in each cell, visually represented by a seven ...

Speckle Skin‐Based Multimodal Tactile Perception for Fine Robotic Manipulation

Advanced Intelligent Systems, EarlyView.
SpeckleTac, a miniature vision‐based tactile sensor, utilizes a speckle‐pattern skin and optical flow‐based scalable virtual marker tracking. Combined with advanced algorithms, it achieves high‐resolution 3D surface reconstruction, precise contact perception, and stable grasping capabilities.

Refined Composite Multiscale Permutation Entropy to Overcome Multiscale Permutation Entropy Length Dependence

IEEE Signal Processing Letters, 2015
Multiscale permutation entropy (MPE) has recently been proposed to evaluate complexity of time series. MPE has numerous advantages over other multiscale complexity measures, such as its simplicity, robustness to noise and its low computational cost.

MULTISCALE COMPLEXITY/ENTROPY [PDF]

Advances in Complex Systems, 2004
We discuss the role of scale dependence of entropy/complexity and its relationship to component interdependence. The complexity as a function of scale of observation is expressed in terms of subsystem entropies for a system having a description in terms of variables that have the same a priori scale.

Topological entropy bounds multiscale entropy

Topology and its Applications, 2023
In this paper, the concept of topological entropy is defined for a discrete dynamical system over a compact metric space \(X\). Section 1 is introductory. Section 2 is devoted to the concept of topological entropy with respect to an observable function: \[ h(f,\varphi)=\sup\{h(f,\varphi,\mathcal{A}); \mathcal{A}\in \mathcal{R}\}, \] where \(f:X\to X ...

Multiscale Entropy for Physical Activity Recognition

Proceedings of the 2020 2nd Asia Pacific Information Technology Conference, 2020
This paper presents the evaluation of multiscale entropy (MSE) as a feature in physical activity recognition compared to the mostly used traditional features. Walking, jogging, and running were chosen as the physical activities for the comparison considering their similarities.

System Design for Data Analysis with Multiscale Entropy

2020 IEEE International Conference on E-health Networking, Application & Services (HEALTHCOM), 2021
An engineered lightweight architecture has been used on the server side for different purposes. One of them was to provide an environment for data collection and analysis. Since most of the data analysis is static- and post-process, there is a challenge to apply existing data analysis to data collected in real time.
