Degenerate-elliptic operators in mathematical finance and higher-order regularity for solutions to variational equations [PDF]

Advances in Differential Equations, 2012
We establish higher-order weighted Sobolev and Holder regularity for solutions to variational equations defined by the elliptic Heston operator, a linear second-order degenerate-elliptic operator arising in mathematical finance.

Re-examining the moderating role of ICT in the nexus between financial development and banking efficiency: evidence from Africa

Cogent Economics & Finance
Studies on the tripartite nexuses among information and communication technology (ICT), financial development (FD), and banking sector efficiency have largely produced mixed findings. More importantly, how countries’ levels of ICT advancement moderate FD-

Improving the adversarial transferability with relational graphs ensemble adversarial attack

Frontiers in Neuroscience, 2023
In transferable black-box attacks, adversarial samples remain adversarial across multiple models and are more likely to attack unknown models. From this view, acquiring and exploiting multiple models is the key to improving transferability.

Phenotypic and genotypic characterization of single circulating tumor cells in the follow‐up of high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Single circulating tumor cells (sCTCs) from high‐grade serous ovarian cancer patients were enriched, imaged, and genomically profiled using WGA and NGS at different time points during treatment. sCTCs revealed enrichment of alterations in Chromosomes 2, 7, and 12 as well as persistent or emerging oncogenic CNAs, supporting sCTC identity.

Global existence of classical solutions for two-dimensional isentropic compressible Navier–Stokes equations with small initial mass

Advances in Difference Equations, 2020
In this paper, we consider the initial-boundary value problem of two-dimensional isentropic compressible Navier–Stokes equations with vacuum on the square domain.
