Heterogeneity in the Global Practice of Central Nervous System Staging in Pediatric Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) is assessed by cell counting and cytomorphology from cerebrospinal fluid (CSF) and is used for treatment stratification worldwide. The ratio of “CNS2” patients in clinical trials ranges from 3% to 40%, with unclear prognostic significance ...

Formability Effects of Variable Blank Holder Force on Deep Drawing of Stainless Steel

open access: yesMATEC Web of Conferences, 2016
This paper investigates the formability effects of variable blank holder force on deep drawing of AISI 304 rectangular cup. Various sets of blank holder forces were set to observe the formability, which was indicated by the percentage of sheet thinning ...

Effect of FDT on microstructure and crystallographic texture of 600 MPa grade high-titanium high-formability ferrite-pearlite pickling steel

open access: yes工程科学学报, 2019
Obtaining a near-γ texture that parallels that of a rolling plane enhances the r value of steel, thereby improving its formability. A high-angle grain boundary with a misorientation greater than 45 degrees is another crucial factor contributing to the ...

Increased Risk of Sarcomas in Children With Congenital Anomalies: Findings From the Genetic Overlap Between Anomalies and Cancer in Kids (GOBACK) Registry Linkage Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric sarcomas are a heterogeneous group of tumors that contribute disproportionately to cancer mortality in children. Although congenital anomalies are among the strongest known risk factors for childhood cancer, the risk of specific sarcoma subtypes among affected individuals has not yet been thoroughly evaluated. Procedure We

Potential of ultrafine grained materials as high performance penetrator materials

open access: yesEPJ Web of Conferences, 2012
The shear formability and the metal jet formability are important for the kinetic energy penetrator and the chemical energy penetrator, respectively. The shear formability of ultrafine grained (UFG) steel was examined, mainly focusing on the effects of ...
