Pediatric Blood &Cancer, EarlyView.ABSTRACT The medical burdens of sickle cell disease (SCD) and transfusion‐dependent β‐thalassemia (TDT) are chronic and cumulative, even in children. Yet the effects expand beyond medications and healthcare visits due to their impacts on school attendance, academic performance, and peer engagement.

State Functional Estimator Design for Linear Delayed Faulty Discrete Systems
IEEE AccessThis paper introduces an innovative and efficient method for estimating the state functional of linear discrete-time systems with delays that are subject to actuator and sensor faults, which are represented by unknown inputs.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Transitioning from pediatric to adult care is a high‐risk period for individuals with sickle cell disease (SCD). An initial observation at one academic medical center suggested a sex‐based disparity in clinic populations, prompting a national investigation.

DNN identification and fault-tolerant control for non-linear systems with unknown faults
The Journal of Engineering, 2019 In this study, dynamical neural networks (DNNs) are used as an online identifier for a class of non-linear systems with unknown actuator faults. By integrating the designed non-linear FD observer with adaptive regulation algorithm, the parameter coupling

Extremal Properties of Linear Dynamic Systems Controlled by Dirac’s Impulse
International Journal of Applied Mathematics and Computer Science, 2020 The paper concerns the properties of linear dynamical systems described by linear differential equations, excited by the Dirac delta function. A differential equation of the form anx(n)(t)+···+a1x′ (t)+a0x(t)= bmu(m)(t)+···+b1u′ (t)+b0u(t) is considered ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Central nervous system (CNS) relapse of neuroblastoma carries a poor prognosis, and craniospinal irradiation (CSI) poses substantial long‐term toxicity in young children. We report a toddler with MYCN‐amplified neuroblastoma harboring somatic ALK R1275Q who developed extensive leptomeningeal relapse with paraplegia.

Event–Based Feedforward Control of Linear Systems with input Time–Delay
International Journal of Applied Mathematics and Computer Science, 2019 This paper proposes a new method for the analysis of continuous and periodic event-based state-feedback plus static feed-forward controllers that regulate linear time invariant systems with time delays.

Adaptive PID controller based on Q-learning algorithm
CAAI Transactions on Intelligence Technology, 2018 An adaptive proportional–integral–derivative (PID) controller based on Q-learning algorithm is proposed to balance the cart–pole system in simulation environment. This controller was trained using Q-learning algorithm and implemented the learned Q-tables

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Heavy menstrual bleeding (HMB) is a common condition among adolescents and young adults (AYAs) and is the leading cause of iron deficiency anemia (IDA) in this population. Growing evidence suggests that social determinants of health (SDOH) influence menstrual bleeding patterns, access to care, and treatment. However, no studies have
