NON-INVASIVE INVERSE PROBLEM IN CIVIL ENGINEERING
Acta Polytechnica CTU Proceedings, 2017 In this contribution we focus on recovery of spatial distribution of material parameters utilizing only non-invasive boundary measurements. Such methods has gained its importance as imaging techniques in medicine, geophysics or archaeology.

Minimal Geometric Deformation: the inverse problem
European Physical Journal C: Particles and Fields, 2018 In this paper we show that any static and spherically symmetric anisotropic solution of the Einstein field equations can be thought as a system sourced by certain deformed isotropic system in the context of Minimal Geometric Deformation-decoupling ...

An inverse nodal problem for integro-differential operators
, 2011 The inverse nodal problem of recovering integral-differential operators with the Sturm–Liouville differential part and the integral part of Volterra type is studied. We reconstruct the potential and the boundary conditions provided the kernel of integral

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Isolated rapid eye movement sleep behavior disorder (iRBD) is a prodromal state for Lewy body disorders and exhibits biological heterogeneity that may influence clinical expression and progression. We examined clinical features in individuals with iRBD and biomarker‐defined synucleinopathy.

INVERSE PROBLEM FOR EINSTEIN-SCALAR FIELD EQUATIONS
, 2022 The paper introduces a method to solve inverse problems for hyperbolic systems where the leading-order terms are nonlinear. We apply the method to the coupled Einstein-scalar field equations and study the question of whether the structure of space-time ...

INVERSE PARTITION PROBLEMS [PDF]
Bulletin of informatics and cybernetics, 1999 Summary: We analyze a partition problem and its inverse problem both in discrete variables and in two continuous ones through dynamic programming. We show that an inverse relation and an enveloping relation hold in each case. It is shown that an optimal solution for the discrete partition can be expressed through either an upper-semi-inverse function ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective We aim to comprehensively analyze how regional tumor and edema characteristics are associated with clinical presentations and survival outcomes in a large cohort of glioblastoma patients. Methods Patients with IDH‐wildtype glioblastoma who received brain MRI from 2010 to 2023 were included.
