New paradigms of computation, which potentially differ from digital computation, together with novel hardware architecture and devices, are anticipated to reduce the exorbitant energy demand for data-processing tasks.

They are suggested to provide the hardware substrate to scale up computational capabilities while improving their energy expenditure and speed. This work provides an orientation map for those interested in the vast topic of memristive systems with application to neuromorphic computing. We address the description of the most notable emerging devices and we illustrate models that capture the complex dynamical behavior of these systems under the dynamical-systems framework developed by Chua. We then review the memristive behavior under the perspective of statistical physics and percolation theory suited to describe fluctuations and disorder which are otherwise precluded in the dynamical-system approach. Percolation theory allows the investigation of these systems at the mesoscopic level, enabling material-independent modeling of non-linear conductance networks.

Diabetes, a complex metabolic disorder affecting millions worldwide, necessitates innovative approaches to enhance monitoring, diagnosis, and therapeutic interventions. Nanotechnology, a burgeoning field that manipulates materials at the nanoscale, offers unprecedented opportunities to address the challenges posed by diabetes. This abstract explores the multifaceted interface between diabetology and nanotechnology, highlighting key areas of integration. Nanotechnology has paved the way for the development of advanced glucose monitoring systems with enhanced accuracy, sensitivity, and patient convenience. Miniaturized biosensors and implantable devices equipped with nanoscale materials enable continuous and real-time glucose monitoring, empowering individuals with diabetes to make timely and informed decisions about their dietary and insulin management. Furthermore, nanotechnology has facilitated breakthroughs in targeted drug delivery, addressing the limitations of conventional therapies in diabetes treatment. Nano-sized drug carriers can improve bioavailability, enable controlled release, and enhance the selectivity of therapeutic agents, minimizing side effects and optimizing treatment outcomes. Moreover, nanoengineered materials have opened avenues for tissue engineering and regenerative medicine, offering the potential to restore damaged pancreatic islets and insulin-producing cells. The amalgamation of diabetology and nanotechnology also holds promise for early disease detection and prevention. Nanoscale diagnostic tools, such as biomarker-based nanoprobes and lab-onchip devices, offer rapid and accurate detection of diabetes-related biomolecules, enabling timely interventions and reducing the risk of complications.
