Corrections (Erratum and Corrigendum)

If a published article contains an error that does not invalidate its overall findings but requires clarification or correction, Journal of EngineX: Advanced Engineering and Technology may issue a formal correction notice.

• Erratum: Refers to errors introduced by the journal during the editorial or production process.
• Corrigendum: Refers to errors identified by the authors after publication.

A formal correction notice will be published and electronically linked to the original article to ensure transparency, accuracy, and traceability of the scientific record.

Withdrawal of Unpublished Articles (Under Review)

Manuscripts that have not yet been officially published may be withdrawn by the authors. To request withdrawal:

• All authors must submit a signed withdrawal request clearly stating the reasons for withdrawal.
• The request must be submitted to the Editorial Office through the journal's official communication channels.
• The Editorial Office evaluates the request and responds to the authors within 15 days at the latest.

Withdrawal requests are evaluated in accordance with the journal's publication ethics principles and relevant guidelines.

Expression of Concern

Journal of EngineX: Advanced Engineering and Technology may publish an Expression of Concern when serious concerns arise regarding the reliability, validity, or ethical integrity of a published article, but the available evidence is insufficient to justify an immediate retraction.

An Expression of Concern may be issued in the following circumstances:

• An investigation into suspected research or publication misconduct is ongoing and is expected to take a considerable amount of time.
• Serious concerns have been raised regarding the accuracy, reliability, or integrity of the published research.
• The available evidence is inconclusive, or a definitive investigation cannot be completed in a timely manner.

The Expression of Concern will be published and linked to the original article to inform readers about the issues under investigation. Once the investigation is completed, the journal will take appropriate action, which may include publishing a correction, retracting the article, or issuing a further statement if the concerns are not substantiated.

Retraction of Published Articles

Journal of EngineX: Advanced Engineering and Technology may retract a published article when there is clear evidence that its findings or conclusions are unreliable or that serious ethical or publication misconduct has occurred.

Retraction may be considered in the following circumstances:

• Clear evidence that the research findings are unreliable due to data fabrication, falsification, manipulation, or significant errors.
• Plagiarism or substantial overlap with previously published work without appropriate acknowledgment.
• Duplicate or redundant publication without proper disclosure or justification.
• Research conducted in violation of applicable ethical standards or without required ethical approval.
• Unauthorized use of copyrighted material, data, or other intellectual property.
• Compromised or manipulated peer-review or publication processes.
• Undisclosed conflicts of interest that may have significantly influenced the research findings or their interpretation.

The decision to retract an article is made by the Editor-in-Chief following an appropriate investigation and consideration of the available evidence. Retraction may be initiated by the journal or requested by the authors.

The purpose of retraction is to correct the scientific record and protect the integrity of scholarly literature, rather than to punish authors.
