A cover letter is required to be submitted accompanying each manuscript. It should be concise and explain why the study is significant, why it fits the scope of the journal, and why it would be attractive to readers, etc.
Here is a guideline of a cover letter for authors' consideration:

In the second paragraph: concisely explain what was done, the main findings and why they are significant;
In the third paragraph: indicate why the manuscript fits the Aims and Scope of the journal, and why it would be attractive to readers;
In the fourth paragraph: confirm that the manuscript has not been published elsewhere and is not under consideration by any other journal. All authors have approved the manuscript and agreed on its submission to the journal. Journal's specific requirements have been met if any.
If the manuscript is contributed to a Special Issue, please also mention it in the cover letter.
If the manuscript was presented partly or entirely in a conference, the author should clearly state the background information of the event, including the conference name, time and place in the cover letter.

2.2 Types of Publications

The journal publishes Original Research Article, Review, Perspective Article, Case Report, Letter, Editorial, etc. There is no restriction on the number of figures, tables and references, provided that the manuscript is concise and comprehensive. For more details about paper type, please refer to the following table.

Manuscript Type	Definition	Word Limit	Abstract	Keywords	Main Text Structure	References
Original Research Article	An Original Research Article describes detailed results from novel research. All findings are extensively discussed.	No less than 5000	Unstructured abstract. No more than 250 words.	3-8 keywords	The main text should include four sections: Introduction, Methods, Results and Discussion.	Approximately 40 references
Review	A Review Article summarizes the literature on previous studies. It usually does not present any new information on a subject.	No less than 5000	Unstructured abstract. No more than 250 words.	3-8 keywords	The main text may consist of several sections with unfixed section titles. We suggest that the author include an "Introduction" section at the beginning, several sections with unfixed titles in the middle part, and a "Conclusion" section in the end.	Approximately 70 references
Case Report	A Case Report details symptoms, signs, diagnosis, treatment, and follows up an individual patient. The goal of a Case Report is to make other researchers aware of the possibility that a specific phenomenon might occur.	1000-1500 (excluding references)	Unstructured abstract. No more than 150 words.	3-8 keywords	The main text should contain four main sections: Introduction, Case presentation, Discussion, and Conclusion.	Approximately 15 references
Editorial	An Editorial is a short article describing news about the journal or opinions of senior Editors or the publisher.	1200 max	None required.	None required	/	Approximately 5 references
Letter to Editor	A Letter to Editor is usually an open post-publication review of a paper from its readers, often critical of some aspect of a published paper. Controversial papers often attract numerous Letters to Editor.	1500 max	Unstructured abstract. No more than 250 words.	3-8 keywords (optional)	/	No more than 20 references
Perspective	A Perspective provides personal points of view on the state-of-the-art of a specific area of knowledge and its future prospects. Links to areas of intense current research focus can also be made. The emphasis should be on a personal assessment rather than a comprehensive, critical review. However, comments should be put into the context of existing literature. Perspectives are usually invited by the Editors.	2000 max	Unstructured abstract. No more than 150 words.	3-8 keywords	/	Approximately 10 references

2.5 Submission Link

Submit an article via https://accscience.com/user/manuscripts/submission?journal_name=IJPS.

3. Research and Publication Ethics

Please refer to ASP Research and Publication Ethics.

4. Authorship

Authorship credit of IJPS should be solely based on substantial contributions to a published study, as specified in the following four criteria:

Substantial contributions to the conception or design of the work, or the acquisition, analysis, or interpretation of data for the work;
Drafting the work or revising it critically for important intellectual content;
Final approval of the version to be published;
Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

All those who meet these criteria should be identified as authors. Authors must specify their contributions in the section Authors' Contributions of their manuscripts. Contributors who do not meet all the four criteria (like only involved in acquisition of funding, general supervision of a research group, general administrative support, writing assistance, technical editing, language editing, proofreading, etc.) should be acknowledged in the section of Acknowledgement in the manuscript rather than being listed as authors.

If a large multiple-author group has conducted the work, the group ideally should decide who will be authors before the work starts and confirm authors before submission. All authors of the group named as authors must meet all the four criteria for authorship.
AI and AI-assisted technologies should not be listed as an author or co-author.

5. Reviewers Suggestions and Exclusions

During the submission process, please suggest three potential reviewers with the appropriate expertise to review the manuscript. The editors will not necessarily approach these referees. Please provide detailed contact information (address, homepage, phone, e-mail address). The proposed referees should neither be current collaborators of the co-authors nor have published with any of the co-authors of the manuscript within the last three years. Proposed reviewers should be from different institutions to the authors. You may identify appropriate Editorial Board members of the journal as potential reviewers. You may suggest reviewers from among the authors that you frequently cite in your paper.

You are welcome to exclude a limited number of researchers as potential Editors or reviewers of your manuscript. To ensure a fair and rigorous peer review process, we ask that you keep your exclusions to a maximum of three people. If you wish to exclude additional referees, please explain or justify your concerns—this information will be helpful for Editors when deciding whether to honor your request.

6. Editors and Journal Staff as Authors

Editorial independence is extremely important and Editorial Office staff do not interfere with editorial decisions.
Editorial staff or Editors shall not be involved in the processing their own academic work. Submissions authored by editorial staff/Editors will be assigned to at least two independent outside reviewers. Decisions will be made by other Editorial Board members who do not have conflicts of interest with the author. Journal staff are not involved in the processing of their own work submitted to any ASP journals.

7. Policy of the Use of AI and AI-assisted Technologies in Scientific Writing

Generative AI and AI-assisted technologies (e.g., large language models) are expected to be increasingly used to create content. In the writing process of manuscripts, using AI and AI-assisted technologies to complete key researcher work, such as producing scientific insights, analyzing and interpreting data or drawing scientific conclusions, is not allowed, and they should only be used to improve the readability and language of manuscripts.

AI and AI-assisted technologies should be used under human control and supervision as they may generate incorrect or prejudiced output, and they should not be listed as an author or co-author, nor cited as an author.

The use of AI and AI-assisted technologies should be disclosed by authors in their manuscripts, and a statement will be required in the final publication.

ASP will keep monitoring the development and adjust the policy when necessary.

8. Conflict of Interests

IJPS requires authors to declare any possible financial and/or non-financial conflicts of interest in the cover letter and back matter, as well as confirm this point when submitting their manuscript in the submission system. If no conflicts of interest exist, authors need to state "The authors declare no conflicts of interest". We also recognize that some authors may be bound by confidentiality agreements, in which cases authors need to state "The authors declare that they are bound by confidentiality agreements that prevent them from disclosing their competing interests in this work".
