Is it time for a paper mill blacklist?

Naunyn Schmiedebergs Arch Pharmacol

January 2025

Independent researcher, Ikenobe 3011-2, Miki-cho, Kagawa-ken, 761-0799, Japan.

Paper mills represent one of science's greatest threats to the integrity of the entire scientific enterprise because they have become entrenched in a culture of the commercialization and corruption of science's assets, whether these be authorships, data sets, entire papers, editorial positions, or influence during editorial processes to favor a culture of unfair publication practices. This journal, which has taken proactive and exemplary steps to deal with this plague of fakery, is no stranger to the workings of such academic criminality, as exemplified by a string of retractions resulting from paper mill interference and association. This letter posits that a public database, and blacklist, of known paper mills is needed, as well as of authors who have a track record of using paper mills, but recognizes that the establishment of such a blacklist may pose practical, legal, and ethical challenges to its implementation and maintenance.

In this Letter, we present a novel, to the best of our knowledge, approach for recovering objects directly from the Fraunhofer diffraction integral, where the diffraction field of an object is approximated by the Fourier transform of this object augmented by an additional phase factor. This phase factor at the observation plane is universal for the diffraction fields generated by objects located at the same plane and illuminated by the same monochromatic plane wave. It can be first extracted from dividing the Fraunhofer diffraction field by the Fourier transform of an object reference.

This Letter introduces a method for identifying the fast axis and phase retardation of wave plates by means of polarization common-path vortex interferometry. The technique utilizes a composite polarized vortex beam interacting with the wave plate under test. By analyzing the azimuth angle of the dark fringe in the interference pattern, the wave plate's characteristics are accurately extracted.

Recent advancements in fluorescence-based biosensor technologies have enabled more precise and accurate Förster Resonance Energy Transfer (FRET) imaging within Agrobacterium-mediated plant transformation systems. However, the application of FRET imaging in plant tissues remains hindered by significant challenges, particularly the time-intensive process of generating transgenic lines and the complications arising from tissue autofluorescence. In contrast, protoplast-based FRET imaging offers a rapid and efficient platform for functional screening and analysis, making it an essential tool for plant research.
