Unique-Solution Single-Sample Complex Dielectric Characterization Through Linear Phase Approximation

IEEE Open Journal of Antennas and Propagation, 2022
This paper presents a transmission-only (TO) approach that solves the long-standing problem of transmission phase ambiguity. The approach considers a linear frequency-dependent phase approximation to derive the phase mode value analytically and uniquely ...

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Ulam-Type Stability Results for Fractional Integro-Delay Differential and Integral Equations via the ψ-Hilfer Operator

Fractal and Fractional
In this article, we investigate a nonlinear ψ-Hilfer fractional order Volterra integro-delay differential equation (ψ-Hilfer FRVIDDE) and a nonlinear ψ-Hilfer fractional Volterra delay integral equation (ψ-Hilfer FRVDIE), both of which incorporate ...

The Unique Periodic Solution of Abel’s Differential Equation

Journal of Mathematics, 2020
In this paper, the existence of a periodic solution for Abel’s differential equation is obtained first by using the fixed-point theorem. Then, by constructing the Lyapunov function, the uniqueness and stability of the periodic solution of the equation ...

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

Uniqueness of solutions and Ulam–Hyers–Mittag-Leffler stability for Hammerstein-type Hilfer delay differential equations of fractional order

Nonlinear Engineering
In this paper, we discuss the existence of a unique solution and Ulam–Hyers–Mittag-Leffler (UHML) stability for a nonlinear Hammerstein-type ψ-Hilfer delay differential equation of fractional order (ψ-HFDDE) in the configuration of several variable time ...

Impact of Radiation Therapy on Physical and Psychosocial Health of Adolescents and Young Adults: A Joint Report From the Children's Oncology Group AYA and Radiation Oncology Committees

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.
