Recently, codes over some special finite rings especially chain rings have been studied. More recently, codes over finite non-chain rings have been also considered. Study on codes over such rings or rings in general is motivated by the existence of some special maps called Gray maps whose images give codes over fields. Quantum error-correcting (QEC) codes play a crucial role in protecting quantum ...

Abstract The current study examined why people take and delete photos with smartphone cameras, participants' recollective experiences saved deleted photos. Two mixed‐methods surveys asked undergraduates (Study 1) an international online sample 2) to review both recently taken from their smartphones' photo album or trash bin.
