Quantum Computation and Arrows of Time

open access: yesEntropy, 2020
Quantum physics is surprising in many ways. One surprise is the threat to locality implied by Bell’s Theorem. Another surprise is the capacity of quantum computation, which poses a threat to the complexity-theoretic Church-Turing thesis.

Acute Neurological Events in Children With Hemoglobin SC Disease: A Multicenter Retrospective Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neurological manifestations in children with hemoglobin SC (HbSC) disease remain insufficiently characterized, particularly regarding acute events. The aim of this study was to describe the spectrum and frequency of acute neurological events in a multicenter cohort of children with HbSC disease.

The arrow of time

open access: yesThe Astrophysical Journal, 1975
A model of the universe which resolves the apparent contradiction between the historical and the thermodynamic arrows of time is presented. Both arrows are reconciled with the almost time-symmetric character of physical laws at the microscopic level. The theory implies that the universe is unfolding in time but not unraveling. (BJG)

Infant Embryonal CNS Tumors: Molecular Insights and Treatment Considerations for Contemporary Pediatric Neuro‐Oncology

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...
