Identifying the space source term problem for time-space-fractional diffusion equation

Advances in Difference Equations, 2020
In this paper, we consider an inverse source problem for the time-space-fractional diffusion equation. Here, in the sense of Hadamard, we prove that the problem is severely ill-posed.

A Self-Error-Correction-Based Reversible Watermarking Scheme for Vector Maps

ISPRS International Journal of Geo-Information, 2023
The existing digital watermarking schemes for vector maps focus mainly on the process of watermark embedding, while few works have been conducted on the topic of the self-optimization of watermark data in the process of watermark detection. There is thus

Flow and Heat Transfer in a Co-Rotating Cavity with Tubes: A Coupled Prediction Model [PDF]

Journal of Applied Fluid Mechanics, 2022
In previous studies, researchers established mathematical models for predicting the pressure coefficient in simple cavities and tubed vortex reducers based on the assumptions of incompressibility and adiabatic reversibility.

Reverse Checking of Quantum Algorithm Execution

IEEE Access, 2020
Verification of quantum computation is critical because undesirable interference and noise are major technical hurdles in quantum computing. We propose an approach for reverse checking of computation results that takes advantage of quantum teleportation ...

Nucleation status of Day 2 pre-implantation embryos, acquired by time-lapse imaging during IVF, is associated with live birth.

PLoS ONE, 2022
The primary purpose of this time-lapse data analysis was to identify the association between the nucleation status of a Day 2 preimplantation embryo and live births following in vitro fertilization (IVF). The retrospective data analysis was based on 2769

A Regularization of the Backward Problem for Nonlinear Parabolic Equation with Time-Dependent Coefficient

International Journal of Mathematics and Mathematical Sciences, 2012
We study the backward problem with time-dependent coefficient which is a severely ill-posed problem. We regularize this problem by combining quasi-boundary value method and quasi-reversibility method and then obtain sharp error estimate between the exact

Reversibility of the duet procedure: Bilateral exchange of a supplementary trifocal sulcus-fixated intraocular lens for correction of a postoperative refractive error

American Journal of Ophthalmology Case Reports, 2020
Purpose: We present the case of a 49-year old female who underwent bilateral exchange of a supplementary trifocal sulcus-fixated intraocular lens (IOL) to correct a residual refractive error.

Label-free immunosensor based on a one-step CTAB intercalated graphene nanocomposite for hepatitis C virus detection

Sensing and Bio-Sensing Research, 2023
A new label-free immunosensor containing cetyltrimethylammonium bromide (CTAB) intercalated-graphene oxide (GO) on a polythiophene (PTh) film one-step electrosynthetized is described for detection of hepatitis C antibodies (Anti-HCV).
