Journal of the Korean Mathematical Society, 2005 The authors consider the quartic moment problem suggested by \textit{R. E. Curto} and \textit{L. A. Fialkow} in [Mem. Am. Math. Soc. 568, 52 p. (1996; Zbl 0876.30033)]. Given complex numbers \(\gamma\equiv\gamma^{(4)}:\gamma_{00}, \gamma_{01}, \gamma_{10}, \gamma_{02}, \gamma_{11}, \gamma_{20}, \gamma_{03}, \gamma_{12}, \gamma_{21}, \gamma_{30 ...

On the completely indeterminate case for block Jacobi matrices
Concrete Operators, 2017 We consider the infinite Jacobi block matrices in the completely indeterminate case, i. e. such that the deficiency indices of the corresponding Jacobi operators are maximal.

On a Nonlinear Moments Problem
Journal of Mathematical Analysis and Applications, 1993 The author investigates the problem to determine a function \(u\in C[a,b]\) if the value of the integral \[ I(g;u):=\int^ b_ ag(u(x))dx \] is known for all \(g\in C(\mathbb{R})\) or only those \(g\) belonging to some countable subset of \(C(\mathbb{R})\). Actually, the existence of a bounded-variation function \(\mu(x;u)\) with \[ I(g;u)={1\over 2\sqrt\

The Role of “Adult‐Onset” Cancer Predisposition Genes in Pediatric Cancer: A Comprehensive Review
Pediatric Blood &Cancer, EarlyView.ABSTRACT Current literature estimates that 10% of pediatric cancers are caused by pathogenic or likely pathogenic (P/LP) germline variants in cancer predisposition genes (CPGs). Variants in CPGs thought to increase cancer risk exclusively during adulthood are referred to as “adult‐onset” CPGs (aoCPGs).

PROBLEM OF PLATE BENDING IN THE MOMENT ASYMMETRIC THEORY OF ELASTICITY
International Journal for Computational Civil and Structural Engineering, 2023 For a number of materials used in modern practice, calculations according to the classical theory of elasticity give incorrect results. To ensure the reliable operation of structures, there is a need for new theories.

Health Literacy, Self‐Efficacy and Knowledge of Sickle Cell Disease Among Caregivers
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Sickle cell disease (SCD) is a hereditary blood disorder in which abnormal haemoglobin leads to severe anaemia, painful crises and organ failure. Caregivers’ health literacy (HL) – their ability to assess, understand and apply information, and interact with healthcare professionals – is crucial for managing children with SCD, yet ...

Exact Controllability of the Heat Equation with Boundary Control and Boundary Noise
MathematicsWe study an exact controllability problem for a system governed by the heat equation with Neumann boundary control and boundary noise. We reduce the control problem to a moment problem for which we establish sufficient conditions for its resolution.
