Abstract: This paper investigates the bounded filtering problem for two-dimensional (2-D) discrete systems with encryption-decryption mechanism (EDM) and dynamic event-triggered mechanism (ETM).

The Voynich manuscript—a mysterious medieval book that has defied translation for centuries—may have been created using a special code developed with the help of cards and dice, a new study suggests.
