uncorrected proofにはないエラーがcorrected proofに出現!?

というわけで以下のメールを送ったところ

I am Tetsuya Akita, corresponding author of the accepted paper in the Journal of Theoretical Biology (YJTBI5852; http://dx.doi.org/10.1016/j.jtbi.2010.01.030), and note that a critical error is generated in corrected proof. The error was not shown in the uncorrected proof:

P7, eqn. 23b
This is what is currently written: [Rc (1-r) P(t)]
This is what it should be: [Rc (1-r) (+1) P(t)]
(note: is a Greek alphabet)

Just in case, I attached the snapshot of the uncorrected proof.
I would appreciate your attention to this matter.

「なんとかねじ込みます」という返事が10分後に来た。こちらの過失ではないにせよ、reprintを購入していなくて申し訳ない気分になってしまった。
