TL;DR: In this paper, a recombinant DNA technology based information encrypting and hiding method and an application is presented, where a plain text is coded into a DNA sequence, preprocessing is carried out on the DNA sequence by adopting the encryption algorithm, and a pseudo-DNA segment is generated; and then the pseudo- DNA segment and a marker gene segment are connected to a DNA plasmid vector by using the restriction enzyme and the ligase, and an obtained recombinant plasmids is further hided into a germ body; finally, a cell which contains confidential information is h

TL;DR: In this article, a double-rail logic-based XOR gate and a complementing circuit are constructed for a single-stranded DNA input, a fuel hairpin and a DNA hairpin fixed to a fold paper substrate.

TL;DR: In this article, a finite-time synchronization sliding-mode control method of a complex chaotic system with unknown parameters was proposed, aiming at a synchronous model of the complex driving system and the complex responding system in synchronization.

TL;DR: In this article, a matrix vector multiplication double-track logic circuit based on DNA composite strand displacements and a method thereof was revealed, and the method comprises the following steps: firstly building a threerow-three-column matrix and three-row-one-column vector multiplication system according to a composite strand displacement combination mechanism; building a third-order matrixvector multiplication operated digit logic circuit; using a double-tracking idea to convert the digit logic circuits into a thirdorder matrix vector multiplications operated dual-track circuit; converting the dual track logic circuit into a seesaw

TL;DR: In this paper, a finite time combination synchronization sliding mode control method for composite chaotic systems with uncertain parameters is proposed, in which two driving systems serve as driving systems and the other one serves as a response system, and a combination error system is obtained.
