If Physics Is an Information Science, What Is an Observer?

open access: yesInformation, 2012
Interpretations of quantum theory have traditionally assumed a “Galilean” observer, a bare “point of view” implemented physically by a quantum system.

How we are misinterpreting physical activity intention – behavior relations and what to do about it

open access: yesInternational Journal of Behavioral Nutrition and Physical Activity, 2019
Background Studies of the physical activity intention-behavior gap, and factors that may moderate the gap (e.g., habit, perceived behavioral control), can inform physical activity promotion efforts.

Social Cognitive Theory and Physical Activity: Examining Gender-Based Prediction Patterns and Theoretical Validity

open access: yesSports
This study explored gender-specific nuances in the applicability of Social Cognitive Theory (SCT) to predict physical activity behavior. This study aimed to determine whether similar or different prediction patterns emerge for men and women, particularly

Novel cyber fault prognosis and resilience control for cyber–physical systems

open access: yesIET Cyber-Physical Systems, 2019
Cyber–physical systems (CPSs) consists of a network, computation, and physical process. Embedded networks, which deliver control and sensing signal, can potentially affect CPSs performance.

Rediscovering orbital mechanics with machine learning

open access: yesMachine Learning: Science and Technology, 2023
We present an approach for using machine learning to automatically discover the governing equations and unknown properties (in this case, masses) of real physical systems from observations.

Monolayer stress microscopy: limitations, artifacts, and accuracy of recovered intercellular stresses. [PDF]

open access: yesPLoS ONE, 2013
In wound healing, tissue growth, and certain cancers, the epithelial or the endothelial monolayer sheet expands. Within the expanding monolayer sheet, migration of the individual cell is strongly guided by physical forces imposed by adjacent cells.

Contributions to nonstationary community theory

open access: yesJournal of Biological Dynamics, 2019
The study of the role of environmental variation in community dynamics has traditionally assumed that the environment is a stationary stochastic process or a periodic deterministic process.

Modelling count, bounded and skewed continuous outcomes in physical activity research: beyond linear regression models

open access: yesInternational Journal of Behavioral Nutrition and Physical Activity, 2023
Background Inference using standard linear regression models (LMs) relies on assumptions that are rarely satisfied in practice. Substantial departures, if not addressed, have serious impacts on any inference and conclusions; potentially rendering them ...

The Effect and Mechanism of Cultural Capital on Chinese Residents’ Participation in Physical Activities

open access: yesFrontiers in Psychology, 2022
BackgroundUsing Bourdieu’s cultural capital theory, this paper discusses the inequality of Chinese urban residents’ participation in physical activities caused by cultural capital and explores the relationship and role of residents’ income and self-rated

Bounds on the Per-Sample Capacity of Zero-Dispersion Simplified Fiber-Optical Channel Models [PDF]

open access: yes, 2018
A number of simplified models, based on perturbation theory, have been proposed for the fiber-optical channel and have been extensively used in the literature. Although these models are mainly developed for the low-power regime, they are used at moderate
