Pediatric Blood &Cancer, EarlyView.ABSTRACT Juvenile xanthogranuloma (JXG) of the central nervous system (CNS) is a rare non‐Langerhans cell histiocytosis. CSF1R mutations have been reported for peripheral JXG, but not in CNS JXG. A 3‐month‐old male presented with fever, lymphadenopathy, and macrocephaly with bulging fontanelles.

Cable Interlayer Slip Damage Identification Based on the Derivatives of Eigenparameters
Sensors, 2018 Cables are the main load-bearing structural components of long-span bridges, such as suspension bridges and cable-stayed bridges. When relative slip occurs among the wires in a cable, the local bending stiffness of the cable will significantly decrease ...

Determining Parental Factors for Clinical Trial Attrition in Pediatric Acute Lymphoblastic Leukemia
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background/Objectives Despite high enrollment rates on Children's Oncology Group (COG) protocols, attrition after initial consent is challenging, introducing bias and prolonging trial completion. While adult oncology literature has identified predictors of withdrawal, little is known about caregiver decision‐making for child participation in ...

Complex dynamics of a nonlinear discrete predator-prey system with Allee effect
Open MathematicsThe transition between strong and weak Allee effects in prey provides a simple regime shift in ecology. In this article, we study a discrete predator-prey system with Holling type II functional response and Allee effect. First, the number of fixed points

On Discrete Time Wilson Systems [PDF]
Journal of Mathematics, 2020 In this paper, we define the discrete time Wilson frame (DTW frame) forl2ℤand discuss some properties of discrete time Wilson frames. Also, we give an interplay between DTW frames and discrete time Gabor frames. Furthermore, a necessary and a sufficient condition for the DTW frame in terms of Zak transform are given.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

The existence of discrete solitons for the discrete coupled nonlinear Schrödinger system
Boundary Value Problems, 2023 In this paper, we investigate the nonlinear coupled discrete Schrödinger equations with unbounded potentials. We find simple sufficient conditions for the existence of discrete soliton solution by using the Nehari manifold approach and the compact ...
