Findings of “greatly enhanced” optics turn out to be, well, greatly enhanced

nature photonicsThe authors of a paper in Nature Photonics have been forced to walk back their article after learning from another group of researchers that their conclusions likely were an, ahem, optical illusion.

The paper, “Greatly enhanced continuous-wave terahertz emission by nano-electrodes in a photoconductive photomixer,” appeared in January 2012 and came from a team led by that included Aaron Danner, an optics expert at the National University of Singapore. As the abstract of the paper explains (to physicists, anyway):

“Way out there” paper claiming to merge physics and biology retracted

dna cell biologyA German professor who claims to have developed “a self-consistent field theory which is used to derive at all known interactions of the potential vortex” will have at least two papers retracted, thanks to the scrutiny of a concerned economist.

The first retraction has already appeared, in DNA and Cell Biology, for a paper by Konstantin Meyl called “DNA and Cell Resonance: Magnetic Waves Enable Cell Communication.” The notice says nothing: Continue reading “Way out there” paper claiming to merge physics and biology retracted

Duplication leads to collapse in Nondestructive Testing

Call it uncreative non-destruction. ntecover

A team from China and, it appears, Mississippi, has lost a paper in Nondestructive Testing and Evaluation for duplicate publication.

Here’s the notice (a PDF): Continue reading Duplication leads to collapse in Nondestructive Testing

“False data” forces retraction of Carbon paper co-authored by postdoc who led to PI’s suspension

carboncoverThere’s a new retraction in the journal Carbon.

The case didn’t involve a Carbon copy — say, plagiarism or duplication — but rather an instance of fraud in a Japanese university, part of a larger case we covered last August.

Here’s the retraction notice for the paper, “The role of Fe species in the pyrolysis of Fe phthalocyanine and phenolic resin for preparation of carbon-based cathode catalysts,” which appeared in August 2010: Continue reading “False data” forces retraction of Carbon paper co-authored by postdoc who led to PI’s suspension

Note to authors: Please don’t use the word “novel” when you plagiarize

compbiomedcoverRetraction Watch Rule 5.1, which governs ironic article titles (and does not actually exist), clearly states that researchers who plagiarize should avoid the use of words like “new” or “novel” when describing their research (or lack thereof). Failure to adhere to Rule 5.1 can lead to embarrassment — as in the case below.

A pair of electrical engineers from Islamic Azad University, in Isfahan, Iran, has lost their 2012 article in Computers in Biology and Medicine, titled “A novel real-time patient-specific seizure diagnosis algorithm based on analysis of EEG and ECG signals using spectral and spatial features and improved particle swarm optimization classifier,” because, well, it wasn’t. Turns out, the researchers lifted data from an Irish group who, several years earlier, had proposed their own “novel algorithm for neonatal seizure detection.”

As the admirably detailed retraction notice explains: Continue reading Note to authors: Please don’t use the word “novel” when you plagiarize

Chemical engineer apologizes for “deliberate lapse,” retracts two papers from Croatian journal

Chemical and Biochemical Engineering QuarterlyA professor of chemical engineering in India has retracted two papers after what he called a “deliberate lapse” of submitting the work without the knowledge of his co-author.

The two papers by Kailas L. Wasewar, then an associate professor in the Chemical Engineering department of Visvesvaraya National Institute of Technology in Nagpur, India — he appears to be at the Indian Institute of Technology, Roorkee now — appeared in 2006 in consecutive issues of Chemical and Biochemical Engineering Quarterly, the official journal of the Croatian Society of Chemical Engineers, Slovenian Chemical Society and Austrian Association of Bioprocess Technology.

The retraction notice appeared in the December issue, following a 27 November letter to the editor: Continue reading Chemical engineer apologizes for “deliberate lapse,” retracts two papers from Croatian journal

Eight papers by anti-terrorism professor retracted for plagiarism

An anti-terrorism researcher at the University of Southern Denmark has had a number of papers in conference proceedings retracted for plagiarism.

Debora Weber-Wulff, who has researched plagiarism for a decade, reports on her blog Copy, Shake, and Paste that eight papers by Nasrullah Memon have been retracted after the Vroniplag website revealed similarities between his work and that of other authors.

According to a university website, Memon is Continue reading Eight papers by anti-terrorism professor retracted for plagiarism

Magnets paper fails to stick as plagiarism leads to retraction

jmmmcoverA group engineers from Iran and Singapore have been forced to retract a paper in the Journal of Magnetism and Magnetic Materials after the article was found to contain incidents of plagiarism.

The article, “Magnetic properties of iron-based soft magnetic composites with MgO coating obtained by sol–gel method,” appeared in April 2010. Sometime later (we’re getting near the three-year mark from the date of publication) it seems, the journal learned that something was amiss with the paper.

As the notice explains: Continue reading Magnets paper fails to stick as plagiarism leads to retraction

Seeing double in Pattern Recognition Letters leads to retraction

patterrecletcoverYou’d think this sort of thing would be, well, obvious to the editors of a journal called Pattern Recognition Letters — could a fox get away with publishing in Henhouse News? — but a group of Lithuanian researchers managed to get a duplicate article into the pages of PRL.

The paper, titled “Application of Bayes linear discriminant functions in image classification,” appeared in the February 2011 issue of PRL. But a very similar version already had been published in a special meeting issue of another journal, Procedia Environmental Sciences. Both are Elsevier titles.

According to the retraction notice: Continue reading Seeing double in Pattern Recognition Letters leads to retraction

University of La Laguna ethics committee finds evidence of misconduct in chemists’ papers

jacsat_v134i049.inddA committee at the University of La Laguna (ULL), in Spain’s Canary Islands, has found evidence of misconduct by two chemists in at least two papers. One of those authors had already been forced to retract a paper in the Journal of the American Chemical Society (JACS).

The story is complicated. Here’s a try at telling it: Continue reading University of La Laguna ethics committee finds evidence of misconduct in chemists’ papers
