Emotion dysregulation and integration of emotion-related brain networks affect intraindividual change in ADHD severity throughout late adolescence

open access: yesNeuroImage, 2021
The course of attention deficit hyperactivity disorder (ADHD) from adolescence into adulthood shows large variations between individuals; nonetheless determinants of interindividual differences in the course are not well understood. A frequent problem in

Computation of forces from deformed visco-elastic biological tissues [PDF]

open access: yes, 2018
We present a least-squares based inverse analysis of visco-elastic biological tissues. The proposed method computes the set of contractile forces (dipoles) at the cell boundaries that induce the observed and quantified deformations.

Inverse nodal problem for a class of nonlocal sturm‐liouville operator

open access: yesMathematical Modelling and Analysis, 2010
Inverse nodal problem consists in constructing operators from the given nodes (zeros) of their eigenfunctions. In this work, the Sturm‐Liouville problem with one classical boundary condition and another nonlocal integral boundary condition is considered.

Optical coherence elastography of 3D bilayer soft solids using full-field and partial displacement measurements

open access: yesMedicine in Novel Technology and Devices, 2022
Characterizing nonhomogeneous elastic property distribution of soft tissues plays a crucial role in disease diagnosis and treatment. In this paper, we will apply the optical coherence elastography to reconstruct the shear modulus elastic property ...

Inverse nodal problems for perturbed spherical Schrödinger operators

open access: yesAnalysis and Mathematical Physics, 2023
The authors examine the inverse nodal problem of identifying \(q\in L^{2}(0,1)\), associated with the singular Sturm-Liouville problem \[ L(\ell,q):=\left(-\dfrac{d^2}{dx^{2}}+\dfrac{\ell(\ell+1)}{x^{2}}+q(x)\right) \text{ for ...

On Inverse Nodal Problem and Multiplicities of Eigenvalues of a Vectorial Sturm-Liouville Problem

open access: yesJournal of Function Spaces, 2020
An m-dimensional vectorial inverse nodal Sturm-Liouville problem with eigenparameter-dependent boundary conditions is studied. We show that if there exists an infinite sequence ynj,rx,λnj,r2j=1∞ of eigenfunctions which are all vectorial functions of type

Remarks on a New Inverse Nodal Problem

open access: yesJournal of Mathematical Analysis and Applications, 2000
The authors weaken the conditions and simplify the proof of a theorem of \textit{X. F. Yang} [A new inverse nodal problem, J. Differ. Equations (to appear)]. It is known that the usual nodal inverse problem developed by \textit{J. R. McLaughlin} [J. Differ. Equations, 73, No. 2, 354-362 (1988; Zbl 0652.34029)] is overdetermined.

The Inverse Nodal problem for the fractional diffusion equation

open access: yesActa Scientiarum: Technology, 2015
In this paper, on a general finite interval, the inverse problem of recovering the potential function for a fractional diffusion equation with new spectral parameter, called the nodal point, is given.
