Uniqueness result for a fractional diffusion coefficient identification problem
Boundary Value Problems, 2019 In this paper, we establish an identifiability result for the coefficient identification problem in a fractional diffusion equation in a bounded domain from the observation of the Cauchy data on particular subsets of the boundary.

Robust Prediction of Single and Multiple Point Protein Mutations Stability Changes
Biomolecules, 2019 Accurate prediction of protein stability changes resulting from amino acid substitutions is of utmost importance in medicine to better understand which mutations are deleterious, leading to diseases, and which are neutral.

Solving Inverse Problems Interestingly
International Journal of Applied Sciences and Smart Technologies, 2020 Inverse problems deal with recovering the causes for a desired or given effect. Their presence across sciences and their theoretical study can be traced to a classic example.

Imaging and Calibration of Electromagnetic Inversion Data With a Single Data Set
IEEE Open Journal of Antennas and Propagation, 2022 Electromagnetic Imaging (EMI) systems use a large number of co-resident antennas usually connected to a Vector Network Analyzer via a switch. A numerical model is used to model the physical electromagnetic problem and an inversion algorithm is used to ...

Inverse Problems Have Inverse Complexity [PDF]
, 2008 In this paper we show that inverting problems of higher complexity is easier than inverting problems of lower complexity. While inverting Σp i3CNFSAT is known to be coNP-complete sideri for i=1 we prove that it remains coNP-complete for i=2 and is in P for all i⩾ 3. Relatedly, we show that inverting Σp i3DNFSAT is in P for all i⩾ 1.

Neural networks for quantum inverse problems
New Journal of Physics, 2022 Quantum inverse problem (QIP) is the problem of estimating an unknown quantum system from a set of measurements, whereas the classical counterpart is the inverse problem of estimating a distribution from a set of observations. In this paper, we present a

Some inverse problems of Fourier optics
Современная математика: Фундаментальные направления, 2023 We consider a general formulation of the problem of signal reconstruction from incomplete a priori information about it and measurements of the intensity of its Fourier transform.

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 ...
