Changes in the helicopter medical service system of L'Aquila (Italy), after the fatal helicopter crash on Monte Cefalone (January 24, 2017). A retrospective study.

Introduction: The use of helicopter emergency medical services is useful for rescuing or transporting highly time-dependent disease patients, from urban remote areas or harsh environments in the hospital, providing advanced pre-hospital life support in an emergency setting.

Study Objective: This study aims to identify changes in mission characteristics, crew composition, and operational procedures within the helicopter emergency medical service (HEMS) system of L'Aquila, Italy, to identify operational patterns, mission characteristics, crew composition and patient outcomes over time, with specific attention to changes implemented after the Monte Cefalone incident.

Methods: Changes in the characteristics of the rescued patients, the helicopter missions, the crew members and the type of interventions were analysed.

A ring resonators optical sensor for multiple biomarkers detection.

In the recent years, the number of Point-Of-Care-Tests (POCTs) available for clinical diagnostic has steadily increased. POCTs provide a near-patient testing with the potential to generate a result quickly so that appropriate treatment can be implemented, leading to improved clinical outcomes compared to traditional laboratory testing. Technological advances, such as miniaturization of sensors and improved instrumentation, have revolutionized POCTs, enabling the development of smaller and more accurate devices.

Red mud treated with KOH: synthesis of sustainable materials from waste for water treatment.

Solid waste resulting from bauxite ore (red mud) was converted into useful products consisting in hydrogarnet together with zeolite. Red mud (RM) transformation from disposal material into new source was carried out using potassium hydroxide as an activator and hydrothermal process (HY) or vapor phase crystallization (VPC) approach. HY process was performed at 60, 90, and 130 °C whereas during the VPC method, red mud was contacted only with vapor from the distilled water heated at 60 and 90 °C.

Time delay reservoir computing with a silicon microring resonator and a fiber-based optical feedback loop.

Silicon microring resonators serve as critical components in integrated photonic neural network implementations, owing to their compact footprint, compatibility with CMOS technology, and passive nonlinear dynamics. Recent advancements have leveraged their filtering properties as weighting functions, and their nonlinear dynamics as activation functions with spiking capabilities. In this work, we investigate experimentally the linear and nonlinear dynamics of microring resonators for time delay reservoir computing, by introducing an external optical feedback loop.
