Math has publication fraud, too

Scholarly publishing in mathematics is unlike many other fields, marked by fewer papers, fewer coauthors per paper and fewer citations. But that doesn’t mean the field is immune to fraud and cheating.

A pair of papers posted to the arXiv addresses the issue of fraudulent publishing in math, particularly metrics gaming, and offers a list of recommendations to help detect and deal with that problem and other fraudulent activities. (The former was also published in the October AMS Notices; the latter will appear in the November issue.) “Fraudulent publishing undermines trust in science and scientific results and therefore fuels antiscience movements,” mathematician Ilka Agricola, lead author of both papers, told Retraction Watch.

A professor of mathematics at Marburg University in Germany, Agricola was president of the German Mathematical Society in 2021-2022 and is chair of the Committee on Publishing of the International Mathematical Union. The new articles are the products of a working group of the IMU and the International Council of Industrial and Applied Mathematics.

University vice chancellor’s work crawling with ‘tortured phrases’

The chief executive of a university in Eastern India whose research is full of tortured phrases – possible signs of plagiarism – had two papers pulled in December after investigations found evidence of “compromised” peer review and other red flags in the publications.

A third article by the executive, Amiya Kumar Rath, has also come under scrutiny, a publisher told us.

Rath became vice chancellor of Biju Patnaik University of Technology in Rourkela in 2023. A computer scientist with more than 100 publications, he is listed as the second author of one of the now-withdrawn works, a 2020 review article on inspecting and grading fruits using machine learning.

High school student who volunteered at NASA-sponsored lab gets retraction

An astronomical society journal has issued its first retraction in its 10-year history — for work done by a NASA researcher and a high school student. The duo set out to confirm an astrophysics law using calculations that assumed the law was true.

The journal, Research Notes of the AAS, is published by the American Astronomical Society. It is not peer-reviewed, nor is it indexed in Clarivate’s Web of Science. The retraction has prompted the journal to revise its policies on reviewing work before publication.

One of the two authors on the retracted 2024 article is Jadon Lam, who at the time was a student at Pleasant Grove High School in Elk Grove, California. Lam is now at the California Institute of Technology in Pasadena studying astrophysics, according to his LinkedIn profile.

‘The fraud was not subtle’: Chemist blames students after ten papers retracted

While reviewing a manuscript for the Journal of Organic Chemistry, Caroline Kervarc-Genre and her colleague, Thibault Cantat, researchers at the French Alternative Energies and Atomic Energy Commission, noticed something unusual.

The nuclear magnetic resonance (NMR) spectra buried in the supplementary information had striking irregularities: The baseline was interrupted in some parts, and the noise was the same from one spectrum to the next. “Noise being inherently random, repeating noise is only possible if the spectra are altered [or] fake,” Kervarc-Genre told Retraction Watch.

Starting to suspect something was wrong, she and Cantat, examined other papers by the lead author. They discovered data appeared to have been edited in several of the author’s latest publications. “The fraud was not subtle,” Kervarc-Genre said.

She had never come across such blatant fraud, she said, and was unsure about what to do, so turned to PubPeer to report the findings. Others soon joined, uncovering more troubling patterns in the work.

Superconductor researcher loses fifth paper

Ranga Dias, the physics researcher whose work on room-temperature superconductors has been retracted after coauthors raised concerns about the data, has lost another paper for the same reason.

This retraction brings Dias’ total to five, by our count.

The University of Rochester in New York, where Dias is an assistant professor, is investigating his work, Science has reported. Washington State University, where Dias obtained his PhD, is also investigating allegations of plagiarism in his thesis.

Dias has not responded to our request for comment about his latest retraction, of a 2021 paper in Physical Review Letters titled “Synthesis of Yttrium Superhydride Superconductor with a Transition Temperature up to 262 K by Catalytic Hydrogenation at High Pressures.” The article has been cited 178 times, according to information presented on its abstract page.

In December, the journal published an expression of concern for the paper, stating it was investigating concerns “regarding the origins and integrity of the transport data” in several of the paper’s figures “with the cooperation of the authors.”

On June 13, the journal retracted the paper. The notice states:

Two papers retracted for plagiarizing a 50-year-old thesis

A math professor in Poland has lost two papers because she plagiarized a doctoral thesis written before the United States had put a man on the moon.

The articles by Daria Michalik, “The decomposition uniqueness for infinite Cartesian products” and “Some remarks on the uniqueness of decomposition into Cartesian product,” published in 2017 and 2016, respectively, were retracted this year from Topology and its Applications over concerns they closely resembled an unpublished 1968 dissertation from Polish topologist Zbigniew Furdzik: “On the properties of certain decompositions of topological spaces into Cartesian products.”

Michalik has associations with the Institute of Mathematics, the same institution with which Furdzik, now deceased, earned his PhD. As of August of 2023, she was a researcher at Jan Kochanowski University in Kielce, Poland.

The retraction statements for both papers read:

One small error for a physicist, one giant blunder for planetary science

For a decade, scientists have been scratching their heads when trying to put a date on primeval events like the crystallization of the magma ocean on the moon or the early formation of Earth’s continental crust.

Their problem? A revised estimate of the half-life of a radioactive isotope called samarium-146 that is used to gauge the age of ancient rocks.

The updated value, published in 2012 in Science, shortened samarium-146’s half-life by a whopping 35 million years, down to 68 million years from the standard estimate of 103. This reset the clock on the solar system’s early history and suggested the oldest rocks on Earth could have formed tens of millions of years earlier than previously thought.

Exclusive: Australia space scientist made up data, probe finds

A space scientist formerly based at the University of Sydney made up data in an unpublished manuscript, an investigation by the institution has found.

The researcher, Joachim Schmidt, “utilised Adobe Photoshop to make up results,” according to a letter dated Feb. 15, 2023, from Emma Johnston, deputy vice-chancellor of research at the University of Sydney, to scientists at the University of Michigan who reported complaints in late 2019 about work by Schmidt and his former professor Iver Cairns to the Australian institution.

“Given the above, the Panel found there had been breaches of the Research Code on the part of Dr Schmidt. The breaches were viewed as serious, and the Panel considered them to be sufficiently serious to warrant a finding of research misconduct as defined in the Australian Code for the Responsible Conduct of Research,” the letter, obtained by Retraction Watch, stated.

Mathematician withdraws preprint – 24 years after initial submission

Twenty-four years after submitting a manuscript on quantum algebra to the preprint server arXiv, a mathematician has now withdrawn it.

Boris Shoikhet, then of the Independent University of Moscow, posted “Lifting formulas, Moyal product, and Feigin spectral sequence,” to arXiv on Oct. 28, 1998, proposing new conjectures in the field of quantum algebra.

Last month, he withdrew the article, with the comment, “The paper has been withdrawn due to a crucial mistake in the arguments.”

Mathematician requests two retractions for “subtle inaccuracies”

A mathematician has requested the retraction of two recently published articles “claiming proofs of big results in number theory,” as one observer put it.

After publication, the author said he “found some subtle inaccuracies” in the work.

The editor-in-chief of the mathematics journal Studia Logica, where the papers were published, posted a notice to the publication’s website weeks ago stating that it had retracted the two articles.

But the online versions of the papers still show no signs of having been retracted, as the editors wait on their publisher, Springer Nature, to process the retractions.
