Energy stable numerical methods for porous media flow type problems
Many problems arising in the context of multiphase porous media flows that take the form of degenerate parabolic equations have a dissipative structure, so that the energy of an isolated system is decreasing along time.

Background PD-L1 staining using long-stored paraffin sections may not be consistent with the true PD-L1 expression of patients. Therefore, it is necessary to explore the expression of PD-L1(SP142) in paraffin sections of invasive breast cancer with ...

Entanglement of formation dynamics of a two-mode system in a common Gaussian noisy channel [PDF]
Entanglement of formation is a measure that has a clear physically motivated definition, namely, it provides a lower bound over all pure-state entanglement decompositions required to create a given state.

Arbitrary order positivity preserving finite-volume schemes for 2D elliptic problems
International audienceThe positivity preservation is very important in most applications solving elliptic problems. Many schemes preserving positivity has been proposed but are at most second-order convergent.

K-Polar Neutrosophic Assessment of Ideological and Political Classroom Teaching in Higher Vocational Colleges Under the Blended Teaching Model [PDF]
We propose a context-coupled extension of k-polar neutrosophic sets in which an interaction matrix 𝐾 explicitly models dependencies among poles. Within this framework, we introduce the 𝐾-fusion operator and a context-aware necessity-possibility pair ...
