Numerical Modelling Approaches for Assessing Improvements to the Flow Circulation in a Small Lake by Cheng He, Quintin Rochfort

“…Towards this end, a preliminary screening suggested that the flow circulation could be increased around a central island (Mask Island) in the northern part of the lake by opening up an existing causeway connecting the mainland and central island. Three-dimensional (3D) hydraulic and transport models were adopted in this paper to investigate the hydraulic conditions under various wind forces and causeway structures. …”

Study on the Durability of Concrete under an Underwater Coupling Environment by Chunhua You, Gen He

“…It is suggested that the water-cement ratio of 0.34 and the cementitious material of 480 kg/m3 be selected for the preparation of the pile foundation concrete; when the content of fly ash is 15%, the antisulfuric acid corrosion ability of the concrete cementitious system can be enhanced and the concrete with 40% mineral powder has strong antichloride ion corrosion ability; the results show that the chloride diffusion coefficient of concrete samples with seven mix proportions is less than 6∗10–12 m2/s, which can meet the durability design requirements and reduce the damage of concrete. …”

Statistical production of Bc mesons in heavy-ion collisions at the LHC energy by Shouxing Zhao, Min He

“…We study the production of Bc mesons via c and bottom (b) quark recombination in a statistical fashion by placing Bc in the position of a member of the family of open b hadrons, which allows us to make quantitative predictions for the modifications of the production fraction (fc) of Bc mesons and its relative production to B mesons in sNN=5.02TeV Pb-Pb collisions with respect to proton-proton (pp) collisions at the same energy. …”

Topsoil Compaction Risk Based on the Different Responses of Soil Structure to Compaction Stress by Huiqing Zhang, Tingfeng He

“…Under 180 kPa of surface contact stress, the soil cone index, aeration porosity, aggregate mean weight diameters, and structure coefficient of the 0–5 cm and 5–10 cm soil layers gradually moved closer to the soil parameter levels of the subsoil layer before compaction. We suggest that the response of the soil structure to compaction stress proceeds along three stages, elastic deformation, plastic deformation without structure failure, and soil structure failure, within which soil structure failure stress and precompression stress are the two key threshold stresses. …”
