Analog Isolated Multilevel Quantizer for Voltage Sensing while Maintaining Galvanic Isolation

CoRR
A low-power, compact device for performing measurements in electrical systems with isolated voltage domains is proposed. Isolated measurements are required in numerous applications. For instance, a measurement of the bus voltage for a system with a high supply voltage and lower isolated local voltage level may be needed for system health monitoring and

Secreted Nonstructural Protein 3 is a Pathogenic Determinant of Orbivirus

Advanced Science, EarlyView.
This study uncovers a conserved PIP2‐dependent secretory pathway of orbivirus NS3 that induces vascular leakage. Pharmacological disruption of PIP2‐NS3 interaction significantly reduces viral pathogenicity and provides protective efficacy in murine models, establishing PIP2‐mediated NS3 secretion as both a key virulence determinant and a promising ...

Triple‐Mode Ferroelectric Thin‐Film Transistor for Hybrid Electrical–Optical Reservoir Computing

Advanced Science, EarlyView.
A triple‐mode ferroelectric thin‐film transistor is developed by integrating Si3N4/HZO/IGZO layers to realize three independent memory modes: electric long‐term, electric short‐term, and optical short‐term. This single‐device architecture functions as both a reservoir and readout layer, achieving 92.43% MNIST accuracy. It offers a fully hardware‐based,

ELECTROTHERAPY IN THE TREATMENT OF PATIENTS AFFECTED BY RABIES: EXPERIMENTS CONDUCTED AT THE “MAGGIORE” HOSPITAL OF MILAN IN 1865 [PDF]

, 2016
During the nineteenth century, the scientific context of rabies treatment was weak due to the lack of the literature on specific nosology of the rabies disease, and unspecific and ineffective therapy approaches.
