The 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):
A 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: Read the rest of this entry »
You’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.
As Werner Heisenberg famously conjectured, you can’t measure an atomic particle’s momentum and position at the same time. But perhaps the principle named for the German physicist and godfather of quantum mechanics should be applied to another important scientific truth: you can’t publish the same article in two different but competing journals.
Just ask a group led by Ted Sargent, a prominent physicist at the University of Toronto. He and his colleagues recently lost a paper in Thin Solid Films — which sounds like it ought to be the name of an indie movie company, dibs! — on quantum dot solar cells. (If those sound familiar to readers of this blog, there’s a good reason. We wrote about the retraction of another quantum dot paper, this one in Nature Photonics, in October of this year.)
Sargent’s article, “Advances in colloidal quantum dot solar cells: The depleted-heterojunction device,” which he wrote with colleagues in Spain and Switzerland, appeared in August 2011. According to the notice: Read the rest of this entry »
For several months now, we’ve been reporting on variations on a theme: Authors submitting fake email addresses for potential peer reviewers, to ensure positive reviews. In August, for example, we broke the story of a Hyung-In Moon, who has now retracted 24 papers published by Informa because he managed to do his own peer review.
Now, Retraction Watch has learned that the Elsevier Editorial System (EES) was hacked sometime last month, leading to faked peer reviews and retractions — although the submitting authors don’t seem to have been at fault. As of now, eleven papers by authors in China, India, Iran, and Turkey have been retracted from three journals.
In August of last year, Mladen Pavičić, chair of physics at the University of Zagreb’s Faculty of Civil Engineering, published a paper in Physical Review Letters on quantum teleportation, “Near-Deterministic Discrimination of All Bell States with Linear Optics.”
Just six days later, after hearing from a physicist in China, Pavičić — who is also affiliated with Harvard’s physics department — submitted a correction, which ran on the journal’s site in November. The correction begins: Read the rest of this entry »
Giving thanks for plagiarism detection software: Catching up on retractions for the sincerest form of flattery
Today, on Thanksgiving in the U.S., Retraction Watch is taking a bit of a holiday as we dig into some turkey — not to be confused with retractions from Turkey. We’d like to give thanks for the thousands of Retraction Watch readers all over the world who’ve helped us shine a spotlight on the scientific process, warts and all.
And we imagine that journal editors around the globe are giving thanks to plagiarism detection software such as iThenticate, so today’s post is a roundup of some recent retractions for plagiarism: Read the rest of this entry »
That certainly sounds bad — if inconclusive — but the authors maintain the whole thing was a simple misunderstanding.
The article, “Plasma Acid: Water Treated by Dielectric Barrier Discharge,” came from the lab of Gary Friedman, a physicist at Drexel University in Philadelphia. The first, and corresponding, author was Natalie Shainsky, an award-winning graduate student at the school.
Maybe it’s an occupational hazard of dealing with quantum physics — uncertainty and all that — but a group of Swiss researchers has retracted their paper on quantum dots after discovering “major errors” that undermined their conclusions.
The article, published in 2010 as a research letter in Nature Photonics, was titled “Polarization-entangled photons produced with high-symmetry site-controlled quantum dots,” by Eli Kapon and colleagues.
