Phase-response analysis of synchronization for periodic flows

open access: yes, 2018
We apply the phase-reduction analysis to examine synchronization properties of periodic fluid flows. The dynamics of unsteady flows are described in terms of the phase dynamics reducing the high-dimensional fluid flow to its single scalar phase variable.

A priori error analysis for transient problems using Enhanced Velocity approach in the discrete-time setting [PDF]

open access: yes, 2018
Time discretization along with space discretization is important in the numerical simulation of subsurface flow applications for long run. In this paper, we derive theoretical convergence error estimates in discrete-time setting for transient problems ...

A comparative numerical simulation study of single-phase flow and water-gas two-phase flow infiltration process in the vadose zone with the layered heterogeneous structure

open access: yesShuiwen dizhi gongcheng dizhi, 2022
The infiltration process in the vadose zone is affected by many factors. A quantitative study of the influence of the layered heterogeneous lithological structure and infiltration rate on the process of water infiltration in the vadose zone is helpful in

Unheard and Under‐Supported: Health‐Related Quality of Life in Children, Adolescents, and Young Adults With Sickle Cell Disease

open access: yesPediatric Blood &Cancer, EarlyView.
Abstract Background Sickle cell disease (SCD) is an autosomal recessive hemoglobinopathy affecting millions of individuals worldwide. The clinical expression and psychosocial burden of SCD vary widely across geographical, cultural, and healthcare system contexts, underscoring the need for setting‐specific approaches to assessment.

On the multispacecraft determination of periodic surface wave phase speeds and wavelengths [PDF]

open access: yes, 2010
Observations of surface waves on the magnetopause indicate a wide range of phase velocities and wavelengths. Their multispacecraft analysis allows a more precise determination of wave characteristics than ever before and reveal shortcomings of ...

Imaging of High‐Risk Neuroblastoma: Recommendations From SIOPEN Radiology and Nuclear Medicine Specialty Committees

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Neuroblastoma is the most common extracranial solid tumor in early childhood. Its clinical behavior is highly variable, ranging from spontaneous regression to fatal outcome despite intensive treatment. The International Society of Pediatric Oncology Europe Neuroblastoma Group (SIOPEN) Radiology and Nuclear Medicine Specialty Committees ...
