Prolonged Corrected QT Interval as an Early Electrocardiographic Marker of Cyclophosphamide‐Induced Cardiotoxicity in Pediatric Hematology and Oncology Patients

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cyclophosphamide (CY) is associated with potentially fatal cardiotoxicity, yet no electrocardiographic indices have been established for early detection of CY‐induced cardiomyopathy. This study aimed to determine whether corrected QT interval (QTc) prolongation can predict early onset of CY‐related cardiac dysfunction in pediatric ...

Developmental Disorders in Children Recently Diagnosed With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Neurocognitive deficits in adult survivors of childhood cancer are well established, but less is known about developmental disorders (DD) arising shortly after cancer diagnosis. Using 2016–2019 linked Ohio cancer registry and Medicaid data, we compared DD among 324 children with cancer and 606,913 cancer‐free controls.

Scalings for unsteady natural convection boundary layer under time-varying heating flux in a small Prandtl number fluid

Case Studies in Thermal Engineering, 2021
The unsteady natural convection boundary layer (NCBL) on a vertical wall heated by time-varying flux in initially quiescent homogeneous fluid with a small Prandtl number (Pr) was studied.

Quantum radiation in external background fields

, 1998
A canonical formalism is presented which allows for investigations of quantum radiation induced by localized, smooth disturbances of classical background fields by means of a perturbation theory approach.

Control to flocking of the kinetic Cucker-Smale model [PDF]

, 2014
The well-known Cucker-Smale model is a macroscopic system reflecting flocking, i.e. the alignment of velocities in a group of autonomous agents having mutual interactions.

Time-Varying Delayed Bilateral Teleoperation Without Force/Velocity Measurements

IEEE Transactions on Control Systems Technology
A bilateral teleoperation control scheme is proposed for the case of time-varying delays in the communication channel. The proposed scheme relies only on joint position measurements to estimate both velocities and external forces by using an extended-state high-gain observer. The estimated signals are in turn employed in a decentralized controller in a

Exercise Interventions in Children, Adolescents and Young Adults With Paediatric Bone Tumours—A Systematic Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Bone tumours present significant challenges for affected patients, as multimodal therapy often leads to prolonged physical limitations. This is particularly critical during childhood and adolescence, as it can negatively impact physiological development and psychosocial resilience.

SAR Image Generation of Ocean Surface Using Time-Divided Velocity Bunching Model [PDF]

Journal of the Korean Institute of Electromagnetic Engineering and Science, 2019
An efficient synthetic aperture radar (SAR) image formulation based on the velocity-bunching model is proposed for a large SAR image integration time. A time-varying ocean surface is generated based on the semi-empirical spectrum proposed by Fung and Lee.
