“…Meanwhile, studies with nonbiological materials, such as silica, [44] clay mineral, [45] and metal-organic frameworks, [46] were also performed to mimic the cellular functions, demonstrating the interactions between the inner and the outer environments, as mimicries of cellular physical or biochemical activities. [44][45][46] In addition, a number of polymersomes (self-assembly of amphiphilic co-polymer [47] or polymerbased liposomes [48] ) or proteinosomes [49] have been also studied with certain advantages over liposomes. [50] Nevertheless, we will focus here more on the size-controlled liposomes or proteoliposomes (which are protein-embedded lipid vesicles) in which phospholipids are still the main components because similarities in size, biocompatibility, and physical properties (e.g., fluidity or permeability) are still the important features of an artificial cell, toward mimicking a living cell.…”

The demand to discover every single cellular component has been continuously increasing along with the development of biological techniques. The bottom‐up approach to construct a cell‐mimicking system from well‐defined and tunable compositions is accelerating, with the ultimate goal of comprehending a biological cell. From among the available techniques, the artificial cell has been increasingly recognized as one of the most powerful tools for building a cell‐like system from scratch. This review summarizes the development of artificial cells, from a pure giant unilamellar vesicle (GUV) to a controllable, self‐fueled proteoliposome, both of which are highly compartmentalized. The basic components of an artificial cell, as well as the optimal conditions required for successful, reproducible GUV formation and protein reconstitution, are discussed. Most importantly, progress in studying the metabolic reactions in and the motility of a reconstituted artificial cell are the main focus of the review. The ability to perform a complicated reaction cascade in a controllable manner is highlighted as a promising perspective to obtaining an autonomous and movable GUV.

“…They consist of nine layers, which are The soil layers and parameters were obtained in our related research (Huang et al, 2019), and the borehole diagram is shown in Figure 5. Here, the p-y curve method (Zhang & Andersen, 2017) is used for simulating pile-soil interactions. The segmentation is taken 1 m, and a spring is set at each node.…”

To investigate the seismic performance of a wind turbine that is influenced by both the ice load and the seismic load, the research proposes a numerical approach for simulating the seismic behavior of a wind turbine on a monopile foundation. First, the fluid-solid coupled equation for the water-ice-wind turbine is simplified by assigning reasonable boundary conditions and solving the motion equation, and the seismic motion equation of the wind turbine is developed. Then, on this basis, we propose a simplified 3D numerical model that can simulate the interactions among the wind turbine, water and sea ice. By conducting shaking table tests, the results demonstrate that the established numerical model is effective. Finally, we investigate the effect of the boundary range and ice thickness on the seismic performance of a turbine under near-field and far-field seismic actions. Research results illustrate that ice changes the distribution form of the hydrodynamic pressure. Moreover, the thickness of the ice greatly influences the seismic behavior, while the influence of the ice boundary range is only within a certain range. Additionally, the ice load decreases the energy-dissipating capacity of the wind turbine, so the earthquake resilience of the wind turbine is significantly decreased.

“…For geotechnical work the ε50 (strain to half the undrained shear strength) was recognised by Matlock (1970) as a useful normalising parameter for soil strains and proposed a power-law model although the non-linearity exponent was assigned a fixed value (Zhang & Anderson, 2017). The use of the ε50 (axial strain to 50% strength mobilisation) was also discussed in the review of Wroth et al (1984).…”

Geotechnical Aspects of Underground Construction in Soft Ground

The Mobilisable Strength Design (MSD) philosophy has been used in various applications related to underground construction, e.g. for analysis of deep foundation and retaining wall performance. MSD requires simple models for the stress-strain behaviour of soils. The use of a mobilisation factor on undrained strength to limit soil mobilisation was introduced in BS8002 in 1994. To assist with MSD calculations, the mobilisation strain framework (MSF) has been developed to allow geotechnical engineers to account for the non-linear behaviour of fine-grained soils in routine geotechnical design. In this paper, triaxial and pressuremeter test data from the London Clay deposit are analysed, using the MSF, to study the effects of anisotropy on both the mobilisation strains and non-linearity exponent. The implications for design of underground constructions are also discussed.
