Physics and Engineering

Physics and Engineering is an academic journal which provides a communication platform for university physics teachers and students. It is supervised by Ministry of Education of China, sponsored by Tsinghua University, published by Tsinghua University Press, under the guidance of University Physics Teaching Steering Committee.

Tsinghua University Press is a member of the Committee on Publication Ethics (COPE), Physics and Engineering, uphold a rigorous peer-review, and we are dedicated to investigating and taking actions to maintain the integrity of the papers based on principles and guidelines of COPE for the potential ethical issues. adhering to its principles and guidelines for addressing misconduct to safeguard the integrity of research.

In cases where there is suspicion of misconduct or alleged fraud, the journal will conduct an investigation in accordance with the principles and flowcharts provided by COPE. If valid concerns arise, the author(s) will be contacted to discuss the matter. The journal and/or publisher may then implement the following measures, among others:

1) If the manuscript is still under review, it may be rejected and returned to the author.

2) If the paper has been published online, the response will vary based on the nature and severity of the violation:

• A correction may be appended to the paper,
• An expression of concern may be issued alongside the paper,
• Or, in extreme cases, a retraction of the paper may be warranted.

Physics and Engineering  acknowledges its responsibility to correct any scientifically relevant errors in published papers that may impact their scientific interpretation. Once approved by the editorial office and Editor-in-Chief (EIC), the paper will be revised accompanied by the publication of a correction. A correction is a distinct publication that is linked to the updated paper. It serves to inform all readers that a significant change has been made, and the updated version is available on the website. Notification will be sent to all relevant indexing databases to ensure that they update their records as well.

Corrections can be submitted if:

• change the authorship OR,
• there are scientifically relevant errors, e.g. missing sections/tables/figures, raw data errors, replacing images, table, and figure errors OR,
• add or remove an entire reference.

Papers that threaten the integrity of the scientific record should be retracted. Physics and Engineering adheres to the following guidelines and procedures for handling retractions.

Please be aware that retraction entails retaining the original publication on the platform with a “Retracted” watermark, and the explanation for the retraction is provided in a note linked to the watermarked paper. A paper will only be fully removed from SciOpen's website and corresponding indexing databases under rare and exceptional circumstances, such as when retaining the article online would be unlawful or pose a risk of substantial harm.

When an investigation is ongoing or the evidence is inconclusive, an Expression of Concern may be issued. Editors believe that it is essential to inform readers about potential issues within the paper to uphold journal’s transparency:

There is a suspicion of academic misconduct within the paper, yet the evidence is insufficient to determine it as such OR

The results of the study are suspected to be unreliable, but the author’s institution is unwilling to initiate an investigation OR

Conflicting interpretations exist among the authors OR

An investigation is in progress, and final conclusions may require an extended period.

Physics and Engineering  adhere to the COPE principles regarding appeals and complaints concerning the peer-review process and editorial decisions. Authors have the right to appeal if they believe their manuscript was unfairly treated during peer review or if they consider the rejection decision to be incorrect. However, to lodge an appeal, authors must present substantial evidence or new information/data that counters the reviewers’ comments and the editors’ decisions.

Authors should submit their appeal letter to the journal’s Editorial Office, directing it to the editors, and include specific responses, evidentiary materials, or any new information/data they wish the journal to consider.

Authors must not submit their manuscript for publication elsewhere until they receive a final decision or decide to withdraw their manuscript from consideration and have informed the journal accordingly. Each appeal is assessed on its individual merits. Editors will consider only one appeal per manuscript, and the EIC’s decision on the appeal is final.

To ensure the research that we published is conducted in an ethical manner, especially the research that involving human subject or animal participants, we require that all submissions should conform to the high ethical standards. We reserve the rights to reject any manuscript which could not meet these requirements of ethical standards, even if authors have obtained ethical approval or if ethical approval is not required.

1) Research involving human subjects

Ethical Approval

For published research based on human subjects (human participants, human tissue, human material or human data), authors must obtain the approval from institutional ethics committee(s) prior to the commencement of the research. The research also need to conform to international ethical and legal standards for research.

Authors should provide evidence that they obtained ethical and/or legal approval prior to conducting the research at submission. Manuscripts should include the name of the local ethics committee that approved the research (or confirmation that such approval is not needed) and the approval number. Authors also need to state how the study conforms to recognized standards (e.g. declaration of Helsinki or the Ethical Review Methods for Biomedical Research involving Humans) in the manuscript.

• Example of the statement: “The research was conducted in accordance with the Declaration of Helsinki, and the protocol was approved by the Ethics Committee of XXX (the approval number).”

2) Participant/patient privacy and informed consent

Published research involving human subjects should ensure that patients’ privacy has not been infringed without prior consent:

Consent to participate

For all published research involving human participants, authors should obtain written consent from the participants prior to the commencement of the research. If the research participants are not adults, or unable to provide informed consent, the written consent must be given from their parents/guardians.

Where consent for participation was not obtained or only verbal informed consent obtained, the journal/editor might ask for the evidence of consent or consent procedures, or even the need for consent was waived by an ethics committee.

Consent to publish

For submissions that include any information which might identify an individual, authors should obtain written informed consent to publish from individual participants (or their parents/guardians if the participant is not an adult or unable to give informed consent). Identifying information includes (but is not limited to) photographs, videos, individual clinical data, written description and any other details that might identify the participant. A statement to confirm that consent to publish has been obtained must be included within the manuscript.

3) Research involving animals, specimens and heritage sites

Research involving animals

For published research involving animal research, authors must obtain the approval from the relevant institutional ethics committee prior to the commencement of the research. The research procedures must comply with relevant local and international animal welfare guidelines.

Authors should provide evidence that they obtained ethical and/or legal approval prior to conducting the research at submission. Manuscripts should include the name of the ethics committee and the approval number.

Research involving specimens

For published research involving the collection of biological specimens (cultivated or wild), samples or fossils, authors should carry out it follow the authors’ institution(s) guideline and national/international regulations. Authors should also comply with the local laws. All such samples must be collected in an ethical and equitable way, and in accordance with relevant applicable laws comply with local legislation, and the manuscript should include a statement of appropriate permissions granted and/or licenses.

The manuscript should include the Ethical Statement of appropriate permissions granted. Voucher specimens must be deposited in an accessible herbarium or other public collection providing access to deposited material. Information on the voucher specimen and who identified it must be included in the manuscript. Editors reserve the rights to reject any manuscript which could not meet these requirements.

4) Clinical trials registration

All clinical trials should make prospective registration in publicly accessible databases (e.g., ClinicalTrials.gov) before participants are enrolled. The clinical trials also need to follow the CONSORT (CONsolidated Standards of Reporting Trials) guideline. Manuscripts should include clinical registration name, registration identification number, the name of the register, and the URL for the registry in accordance with journal instructions.

Authors are encouraged to value the opportunity for publication and uphold the esteemed reputation of Physics and Engineering. Before submitting their work, authors should carefully read and adhere to the following responsibilities:

1) Authorship Conflicts of interest.

Authors should be limited to those who have made a significant intellectual contribution to the theoretical development, system or experimental design, prototype development, execution, and/or the analysis and interpretation of data associated with the work contained in the paper, and contributed to drafting the paper or reviewing and/or revising it for intellectual content. The others who have participated in certain substantive aspects of the research project, should be acknowledged or listed as contributors. AI or AI-assisted technology should not be listed as an author.

Please indicate one author as the corresponding author in the case of papers with multiple authors. The corresponding author should ensure that all authors have seen and approved the final version of the manuscript and have agreed to its submission for publication. Besides, the corresponding author has responsibility for communication with the editorial office, overseeing the publication process and ensuring the integrity of the final document.

Any change to the author list during the editorial process should be approved by all authors, including any who have been removed. The corresponding author should put forward a written application including the consent of all authors before the Editor-in-Chief (EIC) makes final decision for the paper. It can be modified after EIC approval. Requests for a change in authorship will be evaluated and require the publication of a Correction for published papers.

2) Duplication, plagiarism and, originality

Physics and Engineering only publishes original content and authors should ensure the originality of their works. Reuse of text work should be appropriately cited or quoted and permission should be obtained.

Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable in Physics and Engineering All submissions would be checked for plagiarism by the CNKI similarity detection （https://cx.cnki.net/#/userAgreeAllPage?isToHome=&isExterLink=true）. The paper will be regarded as plagiarism and will be rejected once the paper is found more than 20% similar to the previous published article. If plagiarism is detected after publication, an investigation or action would be taken based on the COPE principles on plagiarism.

3) Multiple, redundant publication

Publication of very similar papers based on the same experiment or study constitutes unethical behavior and is unacceptable. Authors should avoid undue fragmentation of their work, that is, unnecessarily splitting a body of work into several shorter papers.

Previous publication on a preprint server such as arXiv, bioRxiv and ChemRxiv could be considered as a subsequent publication in Physics and Engineering, but authors should fully disclose the fact at the time of submission and cite the preprint in the reference. When the paper is published, authors are encouraged to link from the preprint server to the Physics and Engineering publication to enable readers to find, access, and cite the final peer-reviewed version.

The content could be published which first appeared in an author’s thesis or dissertation so long as this is the only form in which it has appeared. It should be noted in the Acknowledgements section of the manuscript and cited accordingly in the Reference section.

The conference paper or abstract should expand the content in order to be considered as original work. Authors should get the permission for reuse if they do not hold its copyright, and it should be cited in the Reference section before submission.

4) The use of AI or AI-assisted technologies

Physics and Engineering follows the COPE position statement when it comes to the use of Artificial Intelligence (AI) and AI-assisted technology in manuscript preparation. TUP is a member of STM, Physics and Engineering also follow the Ethical and Practical Guidelines released by STM Generative AI in Scholarly Communications.

Authors should not list AI and AI-assisted technologies as an author or co-author, nor cite AI as an author. Physics and Engineering will monitor this development and will adjust or refine this policy when appropriate.

Authors should disclose the use of AI and AI-assisted technologies with sufficient details at submission via the cover letter. Authors should carefully review and edit the AI generative materials, and be responsible for any submitted materials containing AI technologies. Furthermore, authors should declare the use of these tools or technology and disclose details of how the AI tool was used within Method, Acknowledgement or other related sections.

Editors are in-house editors and Editorial Board Members (EBMs) who take on an editorial role on behalf of the Publisher. The EIC is ultimately accountable for accepting or rejecting a paper. Editors should exercise their responsibilities based on the EIC or Editorial Board Members’ suggestion of whether the paper needs to be modified or can be published. Editors should obey the responsibilities below:

1) Confidentiality and anonymity

Manuscripts should be handled in a confidential manner. No details should be disclosed to anyone without permission from the author (except the reviewers, potential reviewers, EIC, publisher or the occasion where a formal investigation into the allegations of unethical behavior is being conducted). Editors should respect the independence of the author's ideas.

Physics and Engineering perform Double-blind Peer Review. Editors should keep the reviewer anonymity policy which can protect the review results from the interference of authors.

2) Declaration of competing interests

Editors are required to declare any conflict of interests and they should exclude themselves from handling manuscripts and the peer review process if a competing interest exists.

The manuscript submitted by editors themselves should be handled by other editors who have no conflict of interest. The manuscript submitted by the EIC or an EBM shall be handled and reviewed by another EIC or EBM.

Editors may not use the content in the manuscripts for their own work, and if the topic is too close, the manuscript must be handled by other editors.

3) Fair play and timely evaluation

Editors should treat all manuscripts fairly and timely. Editors should evaluate manuscripts for their intellectual content without regarding to ethnic, religion, nationality, gender, age, or affiliation of the authors. However, the editor may consider the history record of the previous manuscripts submitted by the same authors. Editors can directly reject the manuscript if it is not in accordance with the requirement of a specific journal in the theme, breadth, depth, and English expression.

Editors should follow up on any indications or allegations of questionable research practice timely and consider the appeals which are against editorial decisions fairly and seriously.

4) The use of AI or AI-assisted technologies

The manuscript before publication is a confidential document. Reviewers and editors should not upload the manuscript or any part of it to a public generative AI platform. This confidentiality requirement extends to all communication about the manuscript including any notification or decision letters as they may contain confidential information about the manuscript and/or the authors.

Manuscript review is an essential stage in the process of publishing, and peer review is an essential component of formal scholarly communication. Reviewers have the following responsibilities.

1) Alertness to ethical issues

Reviewers should inform the editor of any similarity between the submitted manuscript and work that is already published or under consideration at other journals.

Reviewers should alert the editor if there is any indication of potential ethical problems including but not limited to ethical concerns regarding animal experiments or studies involving human subjects, scientific misconduct.

2) Confidentiality and anonymity

Reviewers should treat the manuscript and the review process as confidential. The content in the manuscript shall not be shared with others, nor shall reviewers use non-public information contained in a paper to advance their own research or financial interests.

Reviewers should be careful not to reveal their identity to the authors, either in their comments or in metadata for reports submitted in Microsoft Word or PDF format.

3) Declaration of competing interests

Reviewers should report to the editorial office and remove themselves from the peer-review process immediately for any personal or business relationship with the authors or partner of the paper may result in impartial evaluation.

4) Fair play and timely evaluation

Reviewers should focus on the content of the manuscript, avoid personal criticism and evaluate the quality of the manuscript, the level of the experiments and the theory objectively.

• Reviewers should explain and support their judgements.
• Reviewers should identify whether the relevant and important literature has been properly cited or not by the authors. It is absolutely forbidden guiding the authors to cite the reviewer’s own paper.

Any reviewer who feels unqualified to review the manuscript or prompt review will be impossible should notify the editor immediately.

Authors will have chance to double check symbols, formulas, and figure legends before final publication, for these may accidentally have been changed during typesetting. After final publication, substantial changes in content such as new results and corrected values are not allowed without the approval of the Editor-in-Chief. Erratum might be needed for further corrections.

The publisher is committed to the permanent availability and preservation of the published content in Physics and Engineering.

author fees

For manuscripts accepted for publication, a publication charge （RMB 4800）will be charged to the corresponding author. Details regarding payment procedures and the exact amount will be provided upon acceptance.
