Modélisation et caractérisation de la conduction électrique et du bruit basse fréquence de structures MOS à multi-grilles

open access: yes, 2011
Avec la diminution constante des dimensions des dispositifs électroniques, les structures MOS font face à de nombreux effets physiques liés à la miniaturisation.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Dielectric properties in Au/SnO2/n-Si (MOS) structures irradiated under Co-60-gamma rays

open access: yes, 2004
The metal-oxide-semiconductor (MOS) structures with insulator layer thickness range of 55-430 Angstrom were stressed with a bias of 0 V during Co-60-gamma ray source irradiation with the dose rate of 2.12 kGy/h and the total dose range was 0-5 x 10(5) Gy.

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Tailored Synthesis of Heterogenous 2D TMDs and Their Spectroscopic Characterization

open access: yesNanomaterials
Two-dimensional (2D) vertical van der Waals heterostructures (vdWHs) show great potential across various applications. However, synthesizing large-scale structures poses challenges owing to the intricate growth parameters, forming unexpected hybrid film ...

Threshold voltage of nonuniformly doped MOS structures

open access: yes, 1973
The minimum of the HF capacitance and the threshold voltage, for nonuniformly doped MOS structures, are calculated by means of an analytical model containing an adequate definition of the condition of strong surface inversion.

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Migrant Organisations on the Rise after 2015/2016? Between “Projectitis” and the Formation of New Structures and Types

open access: yesSocial Sciences
The paper departs from the observation that the role of migrant organisations (MOs) in Germany has changed significantly since the strong influx of refugees in 2015/16.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
