Early Impact of Childhood Opportunity on Neurocognitive Outcomes in Sickle Cell Disease
Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Neurocognitive impairment is a well‐recognized complication of sickle cell disease (SCD) that begins early in childhood and persists across development. While cerebrovascular injury contributes substantially to risk, neurocognitive deficits are also observed in children without overt or silent cerebral infarctions, suggesting ...

Dispersion management in highly nonlinear, carbon disulfide filled holey fibres [PDF]
We investigate dispersion control in holey fibres incorporating a highly nonlinear liquid. A liquid-core microstructured fibre with extremely high nonlinearity and flat dispersion at telecoms wavelengths is ...

Theoretical and numerical investigations of parametric transfer via difference frequency generation for indirect mid-infrared pulse shaping [PDF]
, 2007 We theoretically and numerically investigate indirect mid-infrared pulse shaping via parametric transfer, specifically difference-frequency generation. We define a quantitative measure for the fidelity of parametric transfer, and investigate the effect ...

Well-posedness of the mixed-fractional nonlinear Schrödinger equation on R2
Partial Differential Equations in Applied Mathematics, 2022 We investigate the well-posedness theory of the 2-D fractional nonlinear Schrödinger equation (NLSE) with a mixed degree of derivatives. Motivated by models in optics and photonics where the light propagation is governed by non-quadratic, fractional, and

Determining Parental Factors for Clinical Trial Attrition in Pediatric Acute Lymphoblastic Leukemia
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background/Objectives Despite high enrollment rates on Children's Oncology Group (COG) protocols, attrition after initial consent is challenging, introducing bias and prolonging trial completion. While adult oncology literature has identified predictors of withdrawal, little is known about caregiver decision‐making for child participation in ...
