Centrality-dependent forward J/ψ production in high energy proton-nucleus collisions

2016

Forward $J/\psi$ production and suppression in high energy proton-nucleus collisions can be an important probe of gluon saturation. In an earlier work we studied this process in the Color Glass Condensate framework and showed that using the Glauber approach to extrapolate the dipole cross section of a proton to a nucleus leads to results closer to experimental data than previous calculations in this framework. Here we investigate the centrality dependence of the nuclear suppression in this model and show a comparison of our results with recent LHC data.

Convective hydration in the tropical tropopause layer during the StratoClim aircraft campaign: pathway of an observed hydration patch

2018

The source and pathway of the hydration patch in the TTL (tropical tropopause layer) that was measured during the Stratospheric and upper tropospheric processes for better climate predictions (StratoClim) field campaign during the Asian summer monsoon in 2017 and its connection to convective overshoots are investigated. During flight no. 7, two remarkable layers are measured in the TTL, namely (1) the moist layer (ML) with a water vapour content of 4.8–5.7 ppmv in altitudes of 18–19 km in the lower stratosphere and (2) the ice layer (IL) with ice content up to 1.9 eq. ppmv (equivalent parts per million by volume) in altitudes of 17–18 km in the upper tropo…

Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei

2008

Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival directions of the cosmic rays with the ighest-energies, which are correlated with the positions of relatively nearby active galactic nuclei (AGN) [Pierre Auger Collaboration, Science 318 (2007) 938]. The correlation has maximum significance for cosmic rays with energy greater than ~6 x 1019 eV and AGN at a distance less than ~75 Mpc. We have confirmed the anisotropy at a confidence level of more than 99% through a test with parameters specified a priori, using an independent data set. The observed correlation is compatible with the hypothesis that cosmic rays with the highest-energies originate fro…

Hypothalamus-specific deletion of socs3 in adult mice enhances hindbrain sensitivity to endogenous satiety signals via oxytocin signaling

2011

Communication sans actes n° 469 (1 page) ; http://www.neurosciences.asso.fr/V2/colloques/SN11/; Leptin is a major contributor to long-term energy homeostasis, through an intracellular transduction pathway involving activation of Stat3 and its feedback inhibitor Socs3, which limits Stat3 activation. Previous studies have shown that Socs3 haploinsufficiency or socs3 deletion in the whole brain or in selective neuronal populations triggers an increased sensitivity to exogenous leptin, through increased Stat3 activation, and protects against diet-induced obesity in mice fed a high fat diet. Intriguingly however, no phenotype was detected when Socs3 mutant mice were maintained under standard die…

Post-translational Modifications in Plant Nuclear Signaling: Novel Insights Into Responses to Environmental Changes

2019

Just imagine a Plant Science professor in front of a classroom full of interested and attentive students. Imagine what their answers to this intriguing question would be: “What are, according to you, the functions ensured by the plant cell nucleus?” It would be very surprising if some of them would answer cell signaling in response to biotic and abiotic stresses or developmental processes. Most of them would probably answer according to a classical point of view: DNA replication or gene expression. Hence it is still admitted in recent publications (see for instance Fedorenko et al., 2010) that molecules smaller than 40 kDa can diffuse freely across the nuclear envelope pores. However, Pauly…
