AI Article Synopsis
Article Abstract
The Sagnac all-optical fiber logic gate functions as a two-input AND gate, a two-input AND gate with one inverting input, or both. The fiber logic gate is pipelined and has a fixed latency. This latency has no effect on feed-forward combinatoric circuits. The latency can be used to time multiplex circuits or to time multiplex gates to emulate a circuit. Possible applications such as a bit-jitter-tolerant communications system, an asynchronous communications system, a bit-interleaved self-routing switching system, an exchange/bypass permutation unit, and a folded universal state machine are discussed.

Diabetic kidney disease (DKD) progression is often marked by early glomerular endothelial cell (GEC) dysfunction, including alterations in the fenestration size and number linked to impaired glomerular filtration. However, the cellular mechanisms regulating GEC fenestrations remain poorly understood due to limitations in existing models, challenges in imaging small fenestrations , and inconsistencies between and findings. This study used a logic-based protein-protein interaction network model with normalized Hill functions for dynamics to explore how glucose-mediated signaling dysregulation impacts fenestration dynamics in GECs.

Smart control of energy interactions plays a key role in manipulating upconversion dynamics and tuning emission colors for lanthanide-doped materials. However, quantifying the energy flux in particular energy migration in the representative sensitizer-activator coupled upconversion system has remained a challenge. Here we report a conceptual model to examine the energy flux in a single nanoparticle by designing an interfacial energy transfer mediated nanostructure.
