Large-basin hydrological response to climate model outputs: uncertainty caused by internal atmospheric variability [PDF]
Hydrology and Earth System Sciences, 2015 An approach is proposed to assess hydrological simulation uncertainty originating from internal atmospheric variability. The latter is one of three major factors contributing to uncertainty of simulated climate change projections (along with so-called ...

Sensitivity analysis of atmospheric low‐frequency variability
Quarterly Journal of the Royal Meteorological Society, 1997 AbstractThe sensitivity of the Pacific‐North‐American (PNA) pattern and the North‐Atlantic Oscillation (NAO) pattern to small perturbations is investigated using adjoint techniques. Analysis is perfomed on integrations of a quasi‐geostrophic (QG) model whose internal low‐frequency variability is realistic.

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications
FEBS Open Bio, EarlyView.This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Variability of the global atmospheric circulation during the past 100 years
Meteorologische Zeitschrift, 2009 In order to better understand climate variability, it is essential to address the underlying variability in the atmospheric circulation. How does the circulation interact with the ocean or land surface? How is it affected by external forcings?

HIV‐1 establishes immediate latency in T cells expressing the viral Nef protein
FEBS Open Bio, EarlyView.Nef is a viral protein often omitted from HIV‐1 reporter viruses. Consequently, its role in viral latency is unclear. We developed three novel dual reporter HIV‐1 derivatives that express Nef and allow for detection of latent and productive infection. Using these reporters, we show that Nef does not affect the establishment of immediate viral latency ...

Traveling Planetary-scale Waves Cause Cloud Variability on Tidally Locked Aquaplanets
The Planetary Science Journal, 2023 Cloud cover at the planetary limb of water-rich Earth-like planets is likely to weaken chemical signatures in transmission spectra, impeding attempts to characterize these atmospheres.

SST-Forced Atmospheric Variability in an Atmospheric General Circulation Model
Journal of Climate, 2005 Abstract From ensembles of 80 AGCM simulations for every December–January–February (DJF) seasonal mean in the 1980–2000 period, interannual variability in atmospheric response to interannual variations in observed sea surface temperature (SST) is analyzed.

FEBS Open Bio, EarlyView.We first identified functional murine mitochondrial N‐formyl peptides (MT‐FPs) and investigated their effects on the in vitro myeloid‐derived suppressor cell (MDSC) generation from bone marrow cells. We demonstrated that MT‐FPs acted directly on bone marrow cells to promote MDSC generation and modulated the polymorphonuclear (PMN)‐MDSC/monocyte (M ...

Radiative Transfer For Variable 3D Atmospheres
, 2022 Pour étudier la température dans un gaz soumis à des rayonnements électromagnétiques, on peut utiliser les équations du transfert radiatif couplées aux équations de Navier-Stokes. Le problème a 7 dimensions ; cependant, avec des simplifications minimales,on peut le réduire à un petit nombre d'équations intégro-différentielles en 3 dimensions.

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations
Advanced Biology, Volume 9, Issue 3, March 2025.Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...
