In the second work by [PERSON] et al. [2], the authors develop an efficient theoretical approach to investigate the nonlocal and size-dependent (NLSD) effects on the dielectric response of plasmonic nanostructures that incorporate the spatially local, nonlocal, size and even analogous quantum-size responses of the material. On the other hand, unlike traditional engineering structural problems, the design of micro-electromechanical systems (MEMS) usually involves microstructures, novel materials, and extreme operating conditions, where multi-source uncertainties usually exist. In such a context, the work by [PERSON] et al. [3] develops an evidence-theory-based robustness optimization method for a robust design of MEMS, including a micro-force sensor, an image sensor, and a capacitive accelerometer of practical interest. Another application is represented by microfluidic devices, for which an analytical and practical method is efficiently proposed in the work by [PERSON] [4] to study the Brownian motion in nanoparticle suspensions, as used in a variety of applications involving the transport of reagents and products to and from structured material surfaces. Among geotechnical engineering applications, the work authored by [PERSON] and [PERSON] [5] provides a useful finite element study for an effective measurement of safety and serviceability of existing metro tunnels during adjacent excavation, in lieu of centrifuge model tests, analytical or semi-analytical methods, or a more expensive in-situ monitoring. In the further work by [PERSON] et al. [6], a quantitative evaluation of the solid displacement induced by a ground loss and shield machine mechanical effect is provided in metro tunnel constructions, based on an elastic half-space Mindlin model. The proportion of stratum displacement caused by each factor was quantitatively analyzed in this work, as a valid guidance for the stratum displacement calculation of shield tunneling in the future. A novel method is also proposed by [PERSON], [PERSON] et al. [7] to define the three-dimensional Greenfield stratum movements caused by a shield tunnel construction, where an elastic half-space model of mirror-sink method is combined with a modified analytical approach to give a useful design tool for underground engineering constructions. An efficient numerical model is, instead, established by [PERSON] et al. [8] to compute the tunnel deformation caused by a circular excavation, while adopting a hypoplasticity nonlinear constitutive model, able to account for path-and strain-dependent soil stiffnesses even at small strains. This method is useful for practical engineering soil-structure problems. The extensive use of composite materials and structures in many engineering applications with complex microstructure and manufacturing processes, requires a thorough attention to their mechanical performances, such as the structural deflection damage and load capacity [9; 10; 11; 12], as well as the buckling and dynamic behavior [13; 14; 15; 16; 17; 18], along with possible related uncertainties and stochastic variations. In this setting, the work authored by [PERSON] and [PERSON] [19] provides a stochastic natural frequency analysis of typical composite structures with micro-scale (constituent-scale) and meso-scale (ply-scale) uncertainties, based on Monte-Carlo simulations and the response surface method. Another numerical model is proposed by [PERSON] et al. [20] to analyze the non-linear time-history of different structural members under the simultaneous effects of far- and near-field earthquakes, as useful for design computational tools. The last work, authored by [PERSON], et al. [21] finally proposes a finite element study of the mechanical behavior of palletized products and polyethylene terephthalate bottles, partially filled with liquid under compressive stress conditions, as commonly occurs during a transportation process.
