Cu2+ binding to Alzheimer's β (Aβ) peptides in amyloid fibrils has attracted broad attention, as it was shown that Cu ion concentration elevates senile plaque and such association of Aβ with triggers the production neurotoxic reactive oxygen species (ROS) H2O2. However, detailed sites structures are still largely unknown for or other aggregates Aβ.

Remote calibration is an advanced methodology that leverages electricity meters, intelligent detection, and computing technologies to enhance efficiency precision significantly. However, current research predominantly focuses on isolated architectures tailored single-laboratory environments. In contrast, distributed remote systems integrate multiple nodes remain in their early developmental stages, despite considerable potential for improving scalability operational efficiency. The purpose...
