A DNA based five-state switch with programmed reversibility.
نویسندگان
چکیده
A programmable switch based on a DNA hairpin loop is functionalised with a rigid or flexible porphyrin or FAM and TAMRA FRET pair, which provides insight into the restructuring of the hairpin as well as porphyrin-porphyrin coupling. The switch contains five discrete states which can be accessed independently and followed by real-time spectroscopy, opening the way to a quinary computing code.

Lithium iron orthosilicate (Li2FeSiO4) with Pmn21 space group is theoritically investigated as a chathode material of Li-ion batteries using density functional theory (DFT) calculations. PBE-GGA (+USIC), WC-GGA, L(S)DA (+USIC) and mBJ+LDA(GGA) methods under spin-polarization ferromagnetic (FM) and anti-ferromagnetic (AFM) procedure are used to investigate the material properties, includin...
متن کاملSelf-healing in payment switches with a focus on failure detection using State Ma- chine-based approaches
Composition, change and complexity have attracted ev- eryone’s attention towards Self-Adaptive systems. These systems, inspired by the human body, are capable of adapting to changes in the inner and outer environment. The main objective of this study is to achieve a more con- venient availability for e-banking services in the payment switch, using self-healing systems and focusing on the failur...

متن کاملTemporal control of i-motif switch lifetimes for autonomous operation of transient DNA nanostructures.
Functional DNA nanotechnology creates increasingly complex behaviors useful for sensing, actuation or computation, as enabled via the integration of dynamic and responsive structural DNA motifs. However, temporally controlled and dynamic DNA structures with programmable lifetimes, that are able to operate autonomously and self-revert to the starting state are challenging to achieve due to tedio...
