In this paper, we propose an ensemble of protocol, sensors, data analysis and methodology to represent results for a better understanding and representation of the musculoskeletal status in the specific case of bedridden patients. In the following paragraph, we will discuss the main results achieved and the different aspects related with this topic.

In this work, we propose an electronic Lévy glass built from graphene nanoribbons in the presence of regions with enhanced spin-orbit coupling. Although electrons in graphene nanoribbons present a low spin-orbit coupling strength, it can be increased by a proximity effect with an appropriate substrate. We consider graphene nanoribbons with different edge types, which contain circular regions with a tunable Rashba spin-orbit coupling, whose diameter follows a power-law distribution.

The formation of small droplets and bubbles in turbulent flows is a crucial process in geophysics and engineering, whose underlying physical mechanism remains a puzzle. In this Letter, we address this problem by means of high-resolution numerical simulations, comparing a realistic multiphase configuration with a numerical experiment in which we attenuate the presence of strong velocity gradients either across the whole mixture or in the disperse phase only.

In the galaxy, it is estimated that more than 40–50 per cent of stars are part of a binary system (Duquennoy & Mayor 1991; Raghavan et al. 2010; Tokovinin 2014a, b). Young binary star systems are commonly surrounded by a circumbinary disc of gas and dust, which are the sites for planet formation. Observations naturally reveal that circumbinary discs are commonly misaligned to the binary orbital plane (e.g. Czekala et al. 2019).

Quasi-periodic oscillation (QPOs) analysis is important for understanding the dynamical behavior of many astrophysical objects during transient events such as gamma-ray bursts, solar flares, magnetar flares, and fast radio bursts. In this paper, we analyze QPO data in low-mass X-ray binary (LMXB) systems, using the Lense-Thirring, Kerr, and approximate Zipoy-Voorhees metrics.
