Dear Dr. Sugiura:
Thank you for the careful comments and revision of your manuscript following receipt of expert comments from two Reviewers. I believe your revisions improved the manuscript but before final acceptance I ask one of the reviewers for further comments if any. After an evaluation of your response to the Reviewers' comments, I have two additional questions:
1) With respect to Comment #2 from Rev. 1, you mention in your written response that you agree with a point raised by Rev 1 here but then do not point out if and how you may have revised the manuscript in response? Can you please clarify? This information may also help the second round of review.
2) As to Comment #1 from Rev. 2, thank you for making the Abstract more informative and explicit. Yet I feel there is more you could do in the Abstract, see for example the 2nd sentence, to clarify "if you are referring to things covered in the paper or in the literature".

If you wish to respond to these comments, I believe you can either upload a revised manuscript now (to make it available for the 2nd round of review), or wait till we hear back from one of the Reviewers whom I asked for a second review to introduce any possible changes associated with my comments above.
With regards
Zoltan Toth
