Proton Gradients and Proton-Dependent Transport Processes in the Chloroplast [PDF]

open access: yesFrontiers in Plant Science, 2016
Proton gradients are fundamental to chloroplast function. Across thylakoid membranes, the light induced -proton gradient is essential for ATP synthesis. As a result of proton pumping into the thylakoid lumen, an alkaline stromal pH develops, which is required for full activation of pH-dependent Calvin Benson cycle enzymes.

Temperature dependence of the electric-field gradient in hcp-Cd from first principles

open access: yes, 2006
We determine the temperature dependence of the electric-field gradient in hcp-Cd from first principles. The calculations are based on the ab initio determination of the phonon density of states spectrum of the solid.

Boundedness, existence and uniqueness results for coupled gradient dependent elliptic systems with nonlinear boundary condition

open access: yesAdvances in Nonlinear Analysis
In this paper, we study coupled elliptic systems with gradient dependent right-hand sides and nonlinear boundary conditions, where the left-hand sides are driven by so-called double phase operators.

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Dynamical Systems Approach of Internal Length in Fractional Calculus

open access: yesEngineering Transactions, 2017
Conventionally, non-local properties are included in the constitutive equations in the form of strain gradient-dependent terms. In case of the second gradient dependence an internal material length can be obtained from the critical eigenmodes in ...

PRESSURE DEPENDENCE OF THE ELECTRIC FIELD GRADIENT AT THE Al NUCLEUS IN GdAl2

open access: yes, 1988
High pressure NMR measurements have been used to show that the temperature dependence of the electric field gradient at the Al sites of GdAl2 cannot be due lattice expansion.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

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.

VELOCITY GRADIENT OF THE FLOOR EXERCISE [PDF]

open access: yesJournal of Applied Sports Sciences, 2019
The methodological classification of the volume of the exercises is in the basis of the multiannual preparation in gymnastics. A number of authors (Dimitrova, 2015; Borisenko, 2000; Fisenko, 2005; Gaverdovskiy, Smolevskiy, 2014) note that for the ...
