When Does a Spin Flip? Arrival Time Distributions and Information Propagation in Discrete Quantum Systems

Entropy
We analyze three distinct approaches to time of arrival (TOA) distributions for discrete quantum systems using a spin-12 particle in a constant magnetic field as a paradigmatic example.

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

Research of underground positioning algorithm based on DOA and TDOA

Gong-kuang zidonghua, 2013
In view of problems that current underground positioning system is sensitive to environmental change and has low positioning accuracy, the paper introduced an underground positioning algorithm based on DOA and TDOA. The algorithm takes advantages of high

Nonnegative deconvolution for time of arrival estimation

2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004
The interaural time difference (ITD) of arrival is a primary cue for acoustic sound source localization. Traditional estimation techniques for ITD based upon cross-correlation are related to maximum-likelihood estimation of a simple generative model.

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.
