A low power and soft error resilience guard‐gated Quartro‐based flip‐flop in 45 nm CMOS technology

IET Circuits, Devices and Systems, 2021
Conventional flip‐flops are more vulnerable to particle strikes in a radiation environment. To overcome this disadvantage, in the literature, many radiation‐hardened flip‐flops (FFs) based on techniques like triple modular redundancy, dual interlocked ...

Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation

Advanced Functional Materials, EarlyView.
This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...

Optimizing Scrubbing by Netlist Analysis for FPGA Configuration Bit Classification and Floorplanning

, 2017
Existing scrubbing techniques for SEU mitigation on FPGAs do not guarantee an error-free operation after SEU recovering if the affected configuration bits do belong to feedback loops of the implemented circuits.
