What are Withdrawn Articles in Press?

Withdrawn Articles in Press are proofs of articles which have been peer reviewed and initially accepted, but have since been withdrawn before being published in this publication. Reasons for withdrawal may be a decision by the author and/or editor, accidental duplication of an article elsewhere, or because the content violates the Elsevier publishing policy in some way. Withdrawn Articles in Press are only visible to users when following an external link, e.g., a PubMed or DOI link. Such Withdrawn Articles in Press are not searchable or otherwise available in ScienceDirect.
