The variation of multiple circular cylinders' drag coefficient was investigated using numerical methods. Moreover, the particle tracking simulation was also performed to show the flow structure and how particles move inside the cylinder array. It was found that the density and location of cylinders have a significant influence on the fluid forces, flow structure, and particle movement inside them.

The streaming potential that originates from water flow in porous media plays an important role in geophysical applications since it is sensitive to groundwater flow. In this work, we develop a physically-based model for the streaming potential in porous media using a bundle of capillary tubes model.

Optimization of the flow cytometric method for analyzing NK cell cytotoxic activity in breast cancer
To establish a protocol for analyzing NK cell cytotoxic activity (NKAc) in breast cancer patients using the flow cytometric technique. Methods: We first optimized the protocol based on the previously published studies, focusing on choosing fluorescent dye concentration, incubation time length, and Effector:Target cell ratio (E:T ratio). Subsequently, we preliminarily applied the established protocol to characterize NKAc in some breast cancer patients and healthy controls.

The heating, ventilation, and air conditioning (HVAC) system consumes a lot of electricity in the building to meet the demand for thermal comfort. The energy recovery ventilator (ERV) has been used in commercial, industrial, and residential buildings to save energy consumption for HVAC systems. In this study, we investigated the efficiency of ERV systems in different construction climate zones in Vietnam and the energy consumption of the sample primary school.

This study investigates how different test parameters—such as flow rate, soil type, moisture content, and confining conditions—affect the erosion behavior of soils. Through controlled hydraulic erosion tests, the research identifies key factors influencing critical shear stress and erosion rates. The findings aim to enhance understanding of soil stability in engineering applications and inform the design of erosion-resistant structures.

In this study, Partial Least Square – Structural Equation Modeling (PLS-SEM) was used to analyze data from the questionnaire survey of 363 customers who are familiar with live streaming platforms in Vietnam. By using SmartPLS for data empirical evaluation and hypotheses testing, research shows that the social presence of a live streaming platform and scarcity have a positive impact on consumer’s flow states, hence inducing consumers’ impulsive buying behaviors.

Predicting the macroscopic permeability of porous media is critical in various scientific and engineering applications. This study proposes a novel model that combines Random Forest (RF) and rime-ice (RIME) optimization algorithm, denoted RIME-RF-RIME, to predict permeability based on six key features covering fluid phase dimensions, geometric characteristics, surrounding phase permeability, and media porosity.

This paper improves the breadth-¯rst search strategy in directed automated random testing (DART) to generate a fewer number of test data while gaining higher branch coverage, namely Static DART or SDART for short. In addition, the paper extends the test data compilation mechanism in DART, which currently only supports the projects written in C, to generate test data for C++ projects.

The formation and development of large-scale structures are primary research subjects in the study of turbulent mixing layers. Visualizing these structures based on published experimental data enhances the understanding of complex flow behaviors, which is the main objective of this article. The authors employed a two-point statistical correlation method to evaluate the size of large vortex structures along the interaction region.

This article focuses on the aerodynamic and acoustic characteristics of both an isolated propeller model and a propeller - boundary surface model. The study uses the Reynoldsaveraged Navier-Stokes (RANS) method combined with Computational Fluid Dynamics techniques to analyze the flow field and wake flow behind the propeller and to determine its basic aerodynamic coefficients.
