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.

Comparisons of climate change characteristics in typical arid regions of the Northern Hemisphere

Frontiers in Environmental Science, 2022
In recent years, with the frequent occurrence of severe drought events, climate change in arid regions has become one of the research hotspots. However, previous studies mainly focused on a specific arid region, and the correlations and differences of ...

Cell water dynamics on multiple time scales [PDF]

Proceedings of the National Academy of Sciences, 2008
Water–biomolecule interactions have been extensively studied in dilute solutions, crystals, and rehydrated powders, but none of these model systems may capture the behavior of water in the highly organized intracellular milieu. Because of the experimental difficulty of selectively probing the structure and dynamics of water in ...

An IRT Analysis of Motive Questionnaires: The Unified Motive Scales [PDF]

, 2012
Multiple inventories claiming to assess the same explicit motive (achievement, power, or affiliation) show only mediocre convergent validity. In three studies (N = 1685) the structure, nomological net, and content coverage of multiple existing motive ...

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.

Multiple Positive Solutions for m-Point Boundary Value Problem on Time Scales

Boundary Value Problems, 2011
The purpose of this article is to establish the existence of multiple positive solutions of the dynamic equation on time scales (ϕ(uΔ(t)))∇+h(t)f(t,u(t),uΔ(t))=0,  t∈(0,T)T, subject to the multi-point ...

WZ Cas – variability on multiple time-scales [PDF]

Astronomy & Astrophysics, 2005
We present results on our long-term velocity monitoring of the C-rich semi-regular variable WZ Cas with a Coravel instrument. Our findings are compared with light changes of the star. We suggest that the two main periods, 366 and 186 d, are due to radial pulsation.

Efficient Approximation of Flow Problems With Multiple Scales in Time [PDF]

Multiscale Modeling & Simulation, 2020
In this article we address flow problems that carry a multiscale character in time. In particular we consider the Navier--Stokes flow in a channel on a fast scale that influences the movement of the boundary which undergoes a deformation on a slow scale in time.

Referral Patterns and Diagnostic Timeliness in Pediatric Cancer: A Hospital‐Based Study in Indonesia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Timely diagnosis and treatment are critical for improving survival among children with cancer. In low‐ and middle‐income countries (LMICs), delays are common and may be influenced by fragmented referral pathways and diagnostic limitations.
