Journal Science Innovation and Technology (SINTECH) recognizes that authors may need to withdraw a submitted manuscript for valid academic, ethical, administrative, or technical reasons. However, manuscript withdrawal must be conducted responsibly and transparently to avoid disruption of the editorial and peer-review process. Authors are expected to carefully prepare and check their manuscript before submission. By submitting a manuscript to the journal, authors confirm that the manuscript is original, has not been published previously, is not under consideration elsewhere, and has been approved by all authors.
