Application of Artificial Neural Networks for Predicting Relative Permeability in Talang Akar Formation [PDF]

E3S Web of Conferences
Relative permeability is a substantial parameter for estimating multi-phase fluid flow in porous rocks. It is a complex physical property that is influenced by the behavior and interactions between the fluid and rock phases.

Evaluation of Core Samples from Low-Porosity and Low-Permeability Carbonate Reservoir with NMR Experiments

Chinese Journal of Magnetic Resonance, 2020
Well logging evaluation of the low-porosity and low-permeability carbonate reservoir is difficult because of its complex mineral composition, difficult to determine rock skeleton parameters, diverse types of reservoir space, complex pore structure and ...

The permeability transition pore complex in cancer cell death [PDF]

Oncogene, 2006
The permeability transition pore (PTP) is a multi-protein complex at contact sites of the inner with the outer mitochondrial membrane. Research over the past years has led to the concept that the PTP occupies a central role in cell death induction.

Simulation Study of the Small-Signal Characteristics of Single-Phase Common-Mode Inductors with Capacitance Cancellation

Applied Sciences
This article proposes a simulation model of single-phase common-mode inductors to evaluate the small-signal characteristic of common-mode inductors when the stray capacitance cancellation method is applied.

Permeability evolution during progressive development of deformation bands in porous sandstones [PDF]

, 2003
[1] Triaxial deformation experiments were carried out on large (0.1 m) diameter cores of a porous sandstone in order to investigate the evolution of bulk sample permeability as a function of axial strain and effective confining pressure.

The Percolation Properties of Electrical Conductivity and Permeability for Fractal Porous Media

Energies, 2019
Many cases have indicated that the conductivity and permeability of porous media may decrease to zero at a nonzero percolation porosity instead of zero porosity.

The negative index of refraction demystified

, 2002
We study electromagnetic wave propagation in mediums in which the effective relative permittivity and the effective relative permeability are allowed to take any value in the upper half of the complex plane.

The selective permeability barrier in the nuclear pore complex [PDF]

Nucleus, 2016
The nuclear pore complex (NPC) mediates the shuttle transport of macromolecules between the nucleus and cytoplasm in eukaryotic cells. The permeability barrier formed by intrinsically disordered phenylalanine-glycine-rich nucleoporins (FG-Nups) in the NPC functions as the critical selective control for nucleocytoplasmic transport.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
