Please notice that preprints can be shared wherever at any time, in line with Elsevier’s sharing coverage. Sharing your preprints e.g. on a preprint server is not going to depend as prior publication (see ‘Multiple, redundant or concurrent publication’ for extra information). To confirm originality, your article may be checked by the originality detection service Crossref Similarity Check. The strategies of extraction and processing in addition to any high quality assurance exams undertaken have to be reported. If a proprietary or licensed product is used, the manufacturer and batch number of the product must be reported at the least. Further particulars on sourcing and quality assurance should also be provided where available from the producer.
