Results of the Childhood Cancer and Leukaemia Group's United Kingdom Relapsed Wilms Tumour Trial

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background The United Kingdom relapsed Wilms tumour (UKW‐R) trial aimed to improve the historically low survival rates after relapse of Wilms tumour (WT) through a prospective national risk‐stratified protocol. The trial also evaluated efficacy and toxicity of high‐dose melphalan.

First-principles calculation of intrinsic defect formation volumes in silicon

open access: yes, 2005
We present an extensive first-principles study of the pressure dependence of the formation enthalpies of all the know vacancy and self-interstitial configurations in silicon, in each charge state from -2 through +2. The neutral vacancy is found to have a

First principles semiclassical calculations of vibrational eigenfunctions [PDF]

open access: yesThe Journal of Chemical Physics, 2011
Vibrational eigenfunctions are calculated on-the-fly using semiclassical methods in conjunction with ab initio density functional theory classical trajectories. Various semiclassical approximations based on the time-dependent representation of the eigenfunctions are tested on an analytical potential describing the chemisorption of CO on Cu(100).

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Theoretical Consideration of Side Reactions between the VS4 Electrode and Carbonate Solvents in Lithium–metal Polysulfide Batteries

open access: yesElectrochemistry, 2022
The lithium/vanadium tetra sulfide (Li|VS4) battery can be considered a promising next-generation battery because of its high theoretical energy density, and it is expected to overcome the problems inherent in Li-S batteries.

First principles calculation of the shift current photovoltaic effect in ferroelectrics. [PDF]

open access: yesPhysical Review Letters, 2012
We calculate the bulk photovoltaic response of the ferroelectrics BaTiO(3) and PbTiO(3) from first principles by applying the "shift current" theory to the electronic structure from density functional theory.

Molecular Methods for Rare Hemoglobinopathy Cases: First Brazilian Report of Pediatric Siblings with Hb O‐Arab and Alpha‐Thalassemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Hemoglobinopathies are prevalent globally; diagnosis is complex in high genetic admixture populations like Brazil. We report, in two pediatric siblings, the first documented cases in Brazil of heterozygosity for hemoglobin (Hb) O‐Arab with coinheritance of α‐thalassemia (αα/−α4.2; −α3.7/−α4.2), resulting in microcytic and hypochromic anemia ...

Photovoltaic properties of metal-free semiconductor DMEDA·I6: A first-principles investigation

open access: yesMaterials Research Express, 2021
Metal-free halide materials have garnered significant attention. However, because of their large band gap, current metal-free materials are not suitable as solar cell absorbers.
