Failure criteria for C/SiC composites under plane stress state
Theoretical and Applied Mechanics Letters, 2014 The applicability and limitation of several quadratic strength theories were investigated with respect to 2D-C/SiC and 2.5D-C/SiC composites. A kind of damage-based failure criterion, referred to as D-criterion, is proposed for nonlinear ceramic ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Adult survivors of childhood acute lymphoblastic leukemia (ALL) are at risk of reduced exercise capacity, decreased physical activity levels, persistent fatigue, and neurocognitive deficits. The aim was to investigate exercise capacity and physical activity levels of adult survivors of childhood ALL and their associations with ...

A Macroscopic Strength Criterion for Isotropic Metals Based on the Concept of Fracture Plane
Metals, 2019 Although the linear Mohr−Coulomb criterion is frequently applied to predict the failure of brittle materials such as cast iron, it can be used for ductile metals too.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric refractory immune thrombocytopenia (rITP) is generally characterized by persistent thrombocytopenia and failure to achieve a sustained response to multiple standard therapies. We report a 4‐year‐old female with congenital tufting enteropathy, post‐intestinal transplant patient on immunosuppressants, who developed severe rITP ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Graft‐versus‐host disease (GvHD) remains one of the most significant complications of hematopoietic stem cell transplantation (HSCT). Abatacept, a selective T‐cell costimulation modulator, is a relatively novel prophylactic agent, though pediatric data remain limited.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Outcomes in relapsed or refractory pediatric and AYA bone sarcomas remain poor, and the impact of early referral to specialized sarcoma centers on survival is unclear. Early centralization of care may improve local and systemic treatment quality, but evidence in this population is limited.
