Pacemaker: evolution and future perspectives

, 2023
reservedL’elettrogenesi nel cuore inizia nel nodo senoatriale e procede a diffondersi tramite il sistema di conduzione dando origine al battito. Disturbi nel sistema di conduzione cardiaco causano aritmie che possono compromettere la qualità della vita ...

Comparative outcomes of high-frequency pacing via a guidewire versus an endocardial electrode during transcatheter aortic valve implantation

Consilium Medicum
Background. Rapid ventricular pacing is routinely used during balloon aortic valvuloplasty and transcatheter aortic valve implantation (TAVI). Temporary right ventricular (RV) pacing via a temporary transvenous pacing lead is the standard approach ...

Comparison of DeePMD, MTP, GAP, ACE and MACE Machine‐Learned Potentials for Radiation‐Damage Simulations: A User Perspective

Advanced Intelligent Discovery, EarlyView.
The authors evaluated six machine‐learned interatomic potentials for simulating threshold displacement energies and tritium diffusion in LiAlO2 essential for tritium production. Trained on the same density functional theory data and benchmarked against traditional models for accuracy, stability, displacement energies, and cost, Moment Tensor Potential ...

Parametric Analysis of Spiking Neurons in 16 nm Fin Field‐Effect Transistor Technology

Advanced Intelligent Discovery, EarlyView.
Energy efficient computing has driven a shift toward brain‐inspired neuromorphic hardware. This study explores the design of three distinct silicon neuron topologies implemented in 16 nm fin field‐Effect transistor technology. While the Axon‐Hillock design achieves gigahertz throughput, its functional fragility persists. The Morris–Lecar model captures

Proto‐Panic Modulation by Caffeine‐Proteinoid Complexes

Journal of Applied Polymer Science, EarlyView.
Caffeine–proteinoid microspheres synthesized by thermal polymerization exhibit compartmentalized drug loading with encapsulation efficiencies of 61%–82% and triphasic release kinetics. Electrochemical monitoring reveals multi‐scale oscillatory dynamics consistent with chaotic and damped harmonic behavior, while Boolean logic operations demonstrate ...
