Inverse Nodal Problem for a Conformable Fractional Diffusion Operator [PDF]

Inverse Problems in Science and Engineering, 2020
In this paper, a diffusion operator including conformable fractional derivatives of order {\alpha} ({\alpha} in (0,1)) is considered. The asymptotics of the eigenvalues, eigenfunctions and nodal points of the operator are obtained.

Shared white matter connectome-based correlates of self-reproach, response failure, spatial planning, and resilience in patients with subthreshold depression: a graph theory approach [PDF]

Scientific Reports
Self-reproach affects decision-making, mediates the impact of social distress on mental health, and is predictive of more severe depressive symptoms in patients with major depressive disorder (MDD) and subthreshold depression (SthD).

The Partial Inverse Spectral and Nodal Problems for Sturm–Liouville Operators on a Star-Shaped Graph

Mathematics, 2022
We firstly prove the Horváth-type theorem for Sturm–Liouville operators on a star-shaped graph and then solve a new partial inverse nodal problem for this operator.

PARALLEL SOLUTION OF THERMOMECHANICAL INVERSE PROBLEMS FOR LASER DIELESS DRAWING OF ULTRA-THIN WIRE [PDF]

Applied Computer Science, 2022
The paper discusses the solving of inverse thermomechanical problems requiring a large number of FEM tasks with various boundary conditions. The study examined the case when all tasks have the same number of nodes, finite elements, and nodal connections.

Inverse Dirichlet-to-Neumann problem for nodal curves [PDF]

Russian Mathematical Surveys, 2012
This paper proposes direct and inverse results for the Dirichlet and Dirichlet to Neumann problems for complex curves with nodal type singularities. As an application, we give a method to reconstruct the conformal structure of a compact surface of the standard three dimensional euclidean space with constant scalar conductivity from electrical current ...
