Magnetization transfer imaging using steady-state free precession MR sequences [PDF]

open access: yes, 2010
Magnetic resonance imaging (MRI) benefits from an exceptional soft tissue contrast and is therefore an important tool for medical diagnosis. While contrast in conventional MRI is generated by protons with free mobility, magnetization transfer (MT ...

Metabolic Flux Analysis—Linking Isotope Labeling and Metabolic Fluxes

open access: yesMetabolites, 2020
Metabolic flux analysis (MFA) is an increasingly important tool to study metabolism quantitatively. Unlike the concentrations of metabolites, the fluxes, which are the rates at which intracellular metabolites interconvert, are not directly measurable ...

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Steady State Tokamak Sustained by Bootstrap Current Without Seed Current [PDF]

open access: yes, 1992
Steady state tokamak solution is studied by taking into account the current diffusivity. The seed current for generating the Bootstrap current is supplied through the radial diffusion of the Bootstrap current.

Steady-state sensitivity analysis for antibiotic concentration.

open access: yes, 2019
The number of bound bacteria, BB, is a monotone decreasing function of the antibiotic concentration, A, in all cases, as are the number of free bacteria, BF, and the total number of bacteria, BT, in Case A.

Variational Matrix Product Operators for the Steady State of Dissipative Quantum Systems. [PDF]

open access: yesPhysical Review Letters, 2015
We present a new variational method based on the matrix product operator (MPO) ansatz, for finding the steady state of dissipative quantum chains governed by master equations of the Lindblad form.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Steady-State Creep of Asphalt Concrete

open access: yesApplied Sciences, 2017
This paper reports the experimental investigation of the steady-state creep process for fine-grained asphalt concrete at a temperature of 20 ± 2 °С and under stress from 0.055 to 0.311 MPa under direct tension and was found to occur at a constant rate ...

The steady-states of splitter networks

open access: yesCoRR
We introduce splitter networks, which abstract the behavior of conveyor belts found in the video game Factorio. Based on this definition, we show how to compute the steady-state of a splitter network. Then, leveraging insights from the players community, we provide multiple designs of splitter networks capable of load-balancing among several conveyor ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.
