The present study conducted a numerical comparison of these two types of tunnels. The results indicated that the presence of an interior column help to increase the stability of the lining structure. The internal forces within the quasi-rectangular tunnel with an interior column are smaller than those of the sub-rectangular tunnel and quasi-rectangular tunnel without an interior column.

The paper presents a case study on the use of in-situ reinforcement technique, namely soil nail, to stabilize a shallow foundation of an existing building constructed on weathered siltstone. The two-dimensional limit equilibrium method was employed to evaluate the stability of the existing foundation with/without incorporating soil nail elements.

Despite numerous studies on racial/ethnic disparities among patients with breast cancer, there is a paucity of literature evaluating racial/ethnic differences in 21-gene recurrence score (RS) and survival diferences stratifed by RS risk categories. We thus performed an observational cohort study to examine racial/ethnic disparities in the context of RS.

Despite the existence of numerous studies investigating the diagnostic potential of blood microRNAs for colorectal cancer, the microRNAs under consideration vary widely, and comparative analysis of their diagnostic value is lacking. Consequently, this systematic review aims to identify the most effective microRNA blood tumor markers to enhance clinical decision-making in colorectal cancer screening.

In this study, we propose to build an equivalent 2D model to replace the 3D model of corrugated composite sheets, by the method of homogenization, to study the nonlinear mechanical behavior of corrugated core composite sheets. This model helps to significantly reduce the calculation time as well as the model building time. The model homogeneity is confirmed by comparing the numerical simulation results of the 2D model and the 3D model.

The objective of the present study is to enhance the hovering efficiency of a UAV helicopter with a spherical fuselage under the effects of the fuselage size (Rf/R) and the distance between the fuselage and rotor (Hm/R), where R is the rotor radius. The RANS method combined with the k-ε turbulent model is used to model the airflow through the helicopter. The numerical model mentioned was well validated by comparing it with the results obtained in the literature.

This paper describes an investigation of fluid flow through two tandem circular cylinders using Lattice-Boltzmann Method in direct numerical simulation. The diameter ratio of two circular cylinders, D1/D2 varies from 0.5 to 1.5, and spacing ratio (L/D2) varies from 1.5 to 10, whereas the Reynolds number of 100 is considered. The numerical model is well validated by comparing the results with those obtained in the literature.

The paper "Dynamic response analysis of nanobeams resting on elastic foundations" uses the finite element method to study the dynamic response of nanobeams resting on an elastic foundation, taking into account the flexoelectricity effect. Timoshenko's first-order shear deformation theory is used to derive the formulations of the beam's forced vibration equation. The proposed theory and mechanical model are verified by comparing the numerical results of this work with those of the published data.
