Clinical Characteristics and Prognostic Risk Factors for Pediatric B‐Cell Lymphoblastic Lymphoma: A Multicenter Retrospective Cohort Study for China Net Childhood Lymphoma

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background B‐cell lymphoblastic lymphoma (B‐LBL) represents a rare variety of non‐Hodgkin lymphoma, with limited research on its biology, progression, and management. Methods A retrospective analysis was performed on the clinical characteristics of 256 patients aged ≤18 years who received treatment under the China Net Childhood Lymphoma (CNCL)‐

On‐line identification of power transformer short‐circuit parameters based on instantaneous phasor

IET Electric Power Applications, 2023
Among the various faults of power transformers, winding faults are particularly common. It is known that short‐circuit parameters can reflect the winding condition, so the on‐line identification of short‐circuit parameters is of great significance for ...

Glass Transition and Lack of Equipartition in a Statistical Mechanics model for Random Lasers

, 2019
Recent experiments suggest that the onset of lasing in optically active disordered media is related to an ergodicity-breaking transition for the degrees of freedom of the electromagnetic field.

Phasor-Based Assessment for Harmonic Sources in Distribution Networks [PDF]

, 2020
Phasor-based interdependencies of multiple harmonic sources, especially Distributed Energy Resources, on distribution networks are analyzed in this paper. A new index, Phasor Harmonic Index (IPH), is proposed by the authors.

Dynamic phasor and frequency estimator for phasor measurement units

IET Generation, Transmission & Distribution, 2010
Synchrophasors and frequency estimations play an increasingly important role in power systems. Discrete Fourier transform (DFT) may introduce errors into phasor and frequency estimations under dynamic conditions, such as power oscillation. A dynamic phasor and frequency estimator for phasor measurement units (PMUs) is proposed to improve accuracy by ...

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.

A Contribution to the Application of the Phasor Transform for Solving Electric Circuits

IEEE Access
This paper presents an alternative analysis of the fundamental concepts underlying the use of the phasor transform in electric circuit analysis. Traditionally, the phasor transform is employed to determine the steady-state response of circuits composed ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
