Comparative Study on Triaxial Test of Undisturbed and Remolded Loess

Mathematical Problems in Engineering, 2022
The difference of sample preparation methods will directly lead to the difference of the structure of the sample, and the mechanical response characteristics under external load will be different. Based on the conventional tests such as particle analysis, specific gravity, critical moisture content, and consolidation test of undisturbed loess from Xi ...

Tumor immune microenvironment predicts the pathologic response of neoadjuvant chemoimmunotherapy in non–small‐cell lung cancer

Cancer Science, Volume 114, Issue 6, Page 2569-2583, June 2023., 2023
Neoadjuvant chemoimmunotherapy for non–small‐cell lung cancer (NSCLC) has achieved an excellent pathological response. The dynamic changes in the tumor immune microenvironment are closely related to the efficacy of neoadjuvant immunotherapy in NSCLC patients.

Study on Energy Dissipation Characteristic of Ice‐Rich Frozen Soil in SHPB Compression Tests

Geofluids, Volume 2022, Issue 1, 2022., 2022
Frozen soil will inevitably bear dynamic loads (impact and blasting) in the construction process in cold regions; the investigation of dynamic energy dissipation characteristic of ice‐rich frozen soil is beneficial to optimize blasting parameters and the design of underground explosion‐proof structure. In this study, the dynamic impact laboratory tests

Effect of Dry‐Wet Cycles on Strength Properties and Microstructure of Lime‐Metakaolin‐Modified Soil

Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
To explore the feasibility of replacing natural hydraulic lime (NHL) with lime‐metakaolin (L‐MK) in the restoration of soil sites, the samples of L‐MK‐modified silty sand (hereinafter L‐MK‐modified soil) underwent 0, 5, 10, and 15 dry‐wet cycles and were then tested for mass loss, unconfined compressive strength, and splitting tensile strength.
