Dual Nature of Electromagnetic (EM) Radiation

Dual Nature of Electromagnetic (EM) Radiation

Electromagnetic (EM) radiation consists of electric and magnetic field components oscillating in planes perpendicular to each other and mutually perpendicular to radiation propagation through space. EM radiation can be classified as a wave, characterized by the properties of waves such as wavelength (denoted as λ) and frequency (represented by ν).
Wavelength is the distance between two consecutive peaks (the highest point) or troughs (the lowest point) in the wave. Frequency is the...

Summary

Duplicate publications in radiology journals are uncommon, occurring at a rate of 1.92 per 1000 citations. While the iThenticate software shows potential for detecting duplicate content, refinements are needed for optimal effectiveness.

Area of Science:

Medical Informatics
Scientific Publishing Ethics

Background:

Duplicate publication, the reuse of a scientific work by its authors without proper citation, poses ethical challenges in academic publishing.
Assessing the prevalence of duplicate publications is crucial for maintaining the integrity of scientific literature.

Purpose of the Study:

To determine the rate of duplicate publication in radiology journals.
To evaluate the sensitivity and effectiveness of the iThenticate software in identifying duplicate publications.

Main Methods:

A comprehensive search of 53 radiology journals from 1993 to 2013 was conducted using the Déjà Vu database and PubMed.
Citations were independently screened by three reviewers using predefined criteria to confirm true duplicate publications.
The sensitivity of iThenticate was assessed by analyzing its performance in detecting identified duplicate publications.

Main Results:

Out of 128,818 citations, 248 were confirmed as true duplicate publications, resulting in an overall rate of 1.92 per 1000 citations.
The rate of duplicate publications varied significantly across journals but showed no correlation with journal impact factor or publication year.
iThenticate identified 61.9% of duplicate publications as "possible duplicates" and correctly paired the duplicate citations in 56.7% of cases.

Conclusions:

Duplicate publications are infrequent in radiology journals, with rates varying widely among publications.
Journal impact factor and publication year were not associated with the rate of duplicate publications.
The iThenticate software demonstrates potential for detecting duplicate publications, though further improvements are recommended to enhance its accuracy.
