Rapid magnetic resonance tissue relaxometry in the steady state [PDF]

open access: yes, 2015
Longitudinal (T1) and transverse (T2) relaxation are the most fundamental physical processes governing the signal intensity and the soft tissue contrast in magnetic resonance imaging (MRI).

SSCAR-Steady State Cycle AnalyseR

open access: yes, 2017
This report describes the Steady-State Cycle AnalyseR (SCCAR), a solution engine that enables the steady state evaluation of thermodynamical cycles. SCCAR can be used to parametrically define thermodynamic cycles using a library of predefined building ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Steady-state solutions.

open access: yes, 2019
Four stacked bars are plotted for each case: the first bar shows the number of free and bound susceptible bacteria, and , at steady-state in the untreated scenario; the second bar shows the number of free and bound resistant bacteria, and , at steady ...

Bidirectional marx DC–DC converter for offshore wind farm application

open access: yesThe Journal of Engineering, 2019
The bidirectional DC–DC converter explained here is based on the Marx principle and is capable of achieving step-up and step-down voltage transformations at kV level and is able to handle MW-level power transfers in both directions.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Steady-state sensitivity analysis for inhibitor doses.

open access: yes, 2019
Note that inhibitor treatments are plotted as multiples of the standard dose (6.12×107 inhib. cm−3). In Cases A and B the number of bound bacteria, BB, is a monotone decreasing function of the inhibitor dose, , while the number of free bacteria, BF ...

Steady-state simulation scenarios, and computation methods for ASA.

open access: yes, 2023
(a) Different scenarios requiring computation of the model steady state. Top: The pre-equilibration case, where the system is at steady state at the beginning of the experiment. This means that by t = t0 the system has reached its steady state (x*) under

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.

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 ...
