NIST Inventors
Gopi Katwala and David Ferraiolo
m-NGAC brings a global solution for RDBMSs by enabling automatic installation of Next Generation Access Control (NGAC) directly into the database, offering out-of-the-box fine-grained database access control. NGAC facilitates building and storing Access control policies, which will be then accessed
(a) Without an aptamer’s protein ligand, dARTs are transcribed to produce RNA outputs (left), while protein binding represses transcription (middle). The input and output domains are decoupled (right), enabling modular design of dARTs by swapping out the aptamer domain or customizing the output sequences. (b) dARTs serve as the protein sensing layer (left) whose outputs can be coupled with downstream circuits (middle). RNA outputs are measured via fluorescence (right).
