Applicability of additive mass method in density tests on soil-mixture materials

Yantu gongcheng xuebao, 2023
The additive mass method (AMM) has been applied in the density tests on different materials of many earth-rockfill dams. With the development of hydropower projects in recent years, the soil-rock mixtures (S-RM) with wide gradation and high fines content

Germline TP53 Mutations Causing Diamond–Blackfan Anemia: A French Report

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Diamond–Blackfan anemia is a rare congenital erythroblastopenia typically caused by mutations in ribosomal protein genes. Recently, gain‐of‐function mutations in TP53 have been identified as a novel cause of Diamond–Blackfan anemia. We report two French patients who both harbored a heterozygous TP53 deletion (NM_000546.5: c.1077delA; p ...

The Role of Invasive Procedures in the Treatment of Complicated Gastrointestinal Graft‐Versus‐Host Disease in Pediatric Patients

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Gastrointestinal graft‐versus‐host disease (GI GVHD) following hematopoietic stem cell transplant is typically managed with medical therapy, but surgery and angioembolization may be warranted in selected cases with life‐threatening complications.

Modified generalized plasticity model for rockfill materials

Yantu gongcheng xuebao, 2017
Within the framework of generalized plasticity theory, the plastic modulus is modified by adding two correction factors to enhance the adaptability of model under high confining stress, thus the generalized plasticity model for sand is successfully ...

Influences of height of leakage point on uncoordinated deformation of heightening canals in cold areas

Yantu gongcheng xuebao, 2020
Due to the periodic changes of water supply and temperature in canals in high cold regions, the canal soils will undergo the "wetting-drying and freeze-thaw" cycles, which will aggravate the uncoordinated deformation of the heightening canals.

Two Faces of NOTCH1 in Childhood Lymphoblastic T‐Cell Neoplasia: Prognostic Divergence of Mutational and Structural Aberrations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT In pediatric patients, T‐cell lymphoblastic lymphoma (T‐LBL) survival exceeds 80%. Relapse remains associated with limited curative options. Frontline treatment is largely extrapolated from T‐cell acute lymphoblastic leukemia (T‐ALL) treatment, reflecting the ongoing debate, whether both entities represent distinct diseases or variants within ...

Generalized plasticity model for rockfill materials

Yantu gongcheng xuebao, 2017
Based on the experimental results and previous studies, the stress ratio at the failure (Mf) under different confining pressures is modified, and the pressure dependency of plastic modulus is discussed.

Fracture failure mechanism and fracture criterion of compacted clay under compression and shear action

Yantu gongcheng xuebao, 2021
Soil cracks are often considered to be caused by tensile-shear stress. In actual engineering, the compacted clay is mostly under compressive-shear stress state.
