Physically consistent simulation of transport of inertial particles in porous media [PDF]

open access: yes, 2011
A new numerical approach is presented for simulating the movement of test particles suspended in an incompressible fluid flowing through a porous matrix.

ShcD adaptor protein drives invasion of triple negative breast cancer cells by aberrant activation of EGFR signaling

open access: yesMolecular Oncology, EarlyView.
We identified adaptor protein ShcD as upregulated in triple‐negative breast cancer and found its expression to be correlated with reduced patient survival and increased invasion in cell models. Using a proteomic screen, we identified novel ShcD binding partners involved in EGFR signaling pathways.

Anomalous diffusion mediated by atom deposition into a porous substrate

open access: yes, 2009
Constant flux atom deposition into a porous medium is shown to generate a dense overlayer and a diffusion profile. Scaling analysis shows that the overlayer acts as a dynamic control for atomic diffusion in the porous substrate.

p-Adic Analogue of the Porous Medium Equation [PDF]

open access: yes, 2016
We consider a nonlinear evolution equation for complex-valued functions of a real positive time variable and a p-adic spatial variable. This equation is a non-Archimedean counterpart of the fractional porous medium equation. Developing, as a tool, an $$L^

Targeting the AKT/mTOR pathway attenuates the metastatic potential of colorectal carcinoma circulating tumor cells in a murine xenotransplantation model

open access: yesMolecular Oncology, EarlyView.
Dual targeting of AKT and mTOR using MK2206 and RAD001 reduces tumor burden in an intracardiac colon cancer circulating tumor cell xenotransplantation model. Analysis of AKT isoform‐specific knockdowns in CTC‐MCC‐41 reveals differentially regulated proteins and phospho‐proteins by liquid chromatography coupled mass spectrometry. Circulating tumor cells

The Toda Flow as a Porous Medium Equation

open access: yesCommunications in Mathematical Physics, 2023
We describe the geometry of the incompressible porous medium (IPM) equation: we prove that it is a gradient dynamical system on the group of area-preserving diffeomorphisms and has a special double-bracket form. Furthermore, we show its similarities and differences with the dispersionless Toda system.

Calculation of the filtration at the porous medium outlet

open access: yesMATEC Web of Conferences, 2018
The study of fluid filtration with solid impurities in a porous medium is necessary for the construction of tunnels, hydraulic structures and underground storage of radioactive waste.

Aberrant expression of nuclear prothymosin α contributes to epithelial‐mesenchymal transition in lung cancer

open access: yesMolecular Oncology, EarlyView.
Nuclear prothymosin α inhibits epithelial‐mesenchymal transition (EMT) in lung cancer by increasing Smad7 acetylation and competing with Smad2 for binding to SNAI1, TWIST1, and ZEB1 promoters. In early‐stage cancer, ProT suppresses TGF‐β‐induced EMT, while its loss in the nucleus in late‐stage cancer leads to enhanced EMT and poor prognosis.

Study of Counting Characteristics of Porous Radiation Detectors [PDF]

open access: yes, 2002
This paper presents the development of a new technology of registration of ionizing radiation and a new type of detectors - single-cathode multiwire porous detector with neither a gaseous nor semiconductor, but a porous dielectric substance, e.g., CsI, being used as working medium.

Derivation of the nonlocal pressure form of the fractional porous medium equation in the hydrological setting [PDF]

open access: yesCommunications in Nonlinear Science and Numerical Simulation 76C (2019), 66-70, 2018
In this short note we consider a nonlinear and spatially nonlocal PDE modelling moisture evolution in a porous medium. We then show that it naturally arises as a description of superdiffusive jump phenomenon occurring in the medium. We provide a deterministic derivation which allows us to naturally incorporate the nonlinear effects.
