Identifying the Digital Camera from Natural Images Using Residual Noise and the Jensen–Shannon Divergence

Journal of Electrical and Computer Engineering, 2022
Regarding the problem of digital camera identification, many methods have been proposed, and for several of them, their effectiveness has been verified on the basis of disputed flat images.

Empowering teachers and fostering pupil climate action in Welsh primary schools

The Curriculum Journal, EarlyView.
Abstract The Curriculum for Wales intends to help students understand and address climate change, but relies on teachers' knowledge and implementation thereof. This article focuses on “The Lifecycle of My Clothes”, a unit of work (UoW) developed by academics and practitioners. The UoW aimed to increase students' awareness of the environmental impact of

Jensen-Shannon divergence as a measure of distinguishability between mixed quantum states

, 2005
We discuss an alternative to relative entropy as a measure of distance between mixed quantum states. The proposed quantity is an extension to the realm of quantum theory of the Jensen-Shannon divergence (JSD) between probability distributions.

Motion‐Compensated Diffusion Imaging With Phase‐Contrast for Robust Quantification of Regional Cerebral Blood Flow

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and evaluate a motion‐compensated diffusion imaging with phase‐contrast (MC‐DIP) technique for mitigating errors in regional cerebral blood flow (rCBF) quantification caused by physiological brain motion. Methods Diffusion‐weighted images were acquired in 11 healthy volunteers on a 3.0 T MRI system using three gradient ...

Quantum-Information Theoretic Properties of Nuclei and Trapped Bose Gases

, 2005
Fermionic (atomic nuclei) and bosonic (correlated atoms in a trap) systems are studied from an information-theoretic point of view. Shannon and Onicescu information measures are calculated for the above systems comparing correlated and uncorrelated cases

Hyperlink prediction via local random walks and Jensen–Shannon divergence

Journal of Statistical Mechanics: Theory and Experiment, 2023
Abstract Many real-world systems involving higher-order interactions can be modeled by hypergraphs, where vertices represent the systemic units and hyperedges describe the interactions among them. In this paper, we focus on the problem of hyperlink prediction which aims at inferring missing hyperlinks based on observed hyperlinks.

Contrasting effects of temperature across trophic levels in geothermally warmed soil food webs

Oikos, EarlyView.
Global warming is altering the structure and dynamics of ecological communities, with significant consequences for soil food webs. Rising temperatures are expected to accelerate metabolic rates in organisms, potentially altering species interactions, and the structure and energetics of food webs.

Pass‐Through of Cocoa Prices Along the Supply Chain: What's Left for Farmers in Côte d'Ivoire?

Journal of Agricultural Economics, EarlyView.
ABSTRACT Most cocoa farmers in Côte d'Ivoire are trapped in a cycle of poverty and farming practices that degrade the environment. This paper aims to provide an in‐depth understanding of the price formation process for cocoa at each stage of the supply chain in the world's largest cocoa‐producing country.

Whose decision is it anyway? Defendants’ prior experience shapes prosecutorial case dismissal

Criminology, EarlyView.
Abstract Studies of early case processing outcomes in the United States typically assume that decisions are made unilaterally by the prosecutor, such that prior contact with the legal system is universally associated with harsher outcomes for defendants.

Relationships of Linear and Non-linear Measurements of Post-stroke Walking Activity and Their Relationship to Weather

Frontiers in Sports and Active Living, 2020
Background: Stroke survivors are more sedentary than the general public. Previous research on stroke activity focuses on linear quantities. Non-linear measures, such as Jensen-Shannon Divergence and Lempel-Ziv Complexity, may help explain when and how ...
