Plaigiarise an American? The French would never do that!
May 21, 2008 at 11:07 am | david | literature, science community, scientific integrityI was recently doing a bit of reading and happened to have two papers on the same subject, short pulse amplification, on my desk at the same time. As I was reading the more recent paper I kept having the feeling that I had just read something very similar. Upon comparison I found that almost the entirety of the more recent paper was plaigiarised from the earlier paper. The French authors even stole a figure from the earlier paper, all without referencing. Ironically the figure that they stole happened to be figure 6 in the original and in their paper, so the text that I copied from the two manuscripts even has the same figure numbers in it! Check out the papers yourself to see just how low people can go in science.

[UPDATE: I wanted to put in the copied figures. See my addition to David’s post below.

Coincidence, I’m sure.

yikes. good eye for catching that!
would papers this old get retracted because of this? they’re both reviews- how does that change things?

Crazy kids and their conspiracy theories.
“making the recompression more difficult for very short pulses”
“making it more difficult to recompress very short pulses”
These are very different sentences of course!

good eye, david. that’s pretty disgusting.

Despicable!

holy shit, figure 6 is copied exactly. like right-click copy, CTRL-P copied. that’s really bad.

i think you should contact the authors of the first paper, or the editors of RSI.
Comment by sam — May 21, 2008 #
the second paper has formated their paper such that the figure is also 6(b). comedy gold.

At least they bothered to change the citation numbers.

Unbelievable. What are they thinking?

UNIX thinks they are different enough lol……
Same program used by the editor?

materials due to the Pockels cells and polarizers can add high-order dispersion to an amplifier system, making the recompression more difficult for very short pulses. Nevertheless, regenerative amplifiers have also been used to
> generate pulses of 30 fs and shorter duration [36, 37].

A multipass preamplifier configuration (figure 6(b)) differs from the regenerative amplifier in that, as its name suggests, the beam passes through the gain medium multiple times without the use of a cavity. The particular geometry

You absolutely should contact the editors of the two journals. This is really, really bad. We both know that this would get you thrown out of Stanford, to say the least.

Ugh. Do we now need to treat paper authors like undergraduates and check their submissions against Turnitin.com?

Impressive. I am not sure the nationality of the authors is relevant, though.

This kind of plagiarism is (unfortunately) quite frequent, at least for introductory-type sentences. What do you think of this one?
“The discovery of superconductivity in H2O-intercalated Na0.33Co2 has reopened investigations of the physical properties of NaxCoO2 compounds, which remained largely unexplored so far. In the simplest picture, the Co planes contain x nonmagnetic (S=0) Co3+ ions and 1-x (S=1/2) spins (Co4+ low-spin state). One of the surprises in the emerging phase diagram is thus the presence of magnetic order at rather low Co4+ concentrations x>0.75. The origin of this order and how it evolves with x are presently unknown or controversial. These questions are directly related to the electronic state of Co and to the microscopic organization within CoO2 layers.”

Nice catch. Kinda funny if you ask me!
