DNA-based data storage platforms traditionally encode information only in the nucleotide sequence of the molecule. Here we report on a two-dimensional molecular data storage system that records information in both the sequence and the backbone structure of DNA and performs nontrivial joint data encodin...
parity-checker circuits using a WSe2neuristor and a MoS2neuristor in a two-transistor two-resistor configuration, offering an area saving of 78% compared to circuits based on MoS2gates in a traditional design. We also propose a binary neural network that is based on a three-dimensional XNOR ...
The invention provides an error detection and correction method, system and device based on two-way parity check, wherein a check digit d is added when parity check codes are added to blocked data, the check digit d ensures that a row check digit is associated with a column check digit, ...
