Influence of Magnetic Field on Effective Electron-Electron Interactions in a Copper Wire [PDF]

open access: yesarXiv, 2001
We have measured in a copper wire the energy exchange rate between quasiparticles as a function of the applied magnetic field. We find that the effective electron-electron interaction is strongly modified by the magnetic field, suggesting that magnetic impurities play a role on the interaction processes.

High genetic carrier frequency of Wilson’s disease in France: discrepancies with clinical prevalence

open access: yesBMC Medical Genetics, 2018
BackgroundWilson’s disease (WD) is a rare autosomal recessive metabolic disease caused by ATP7B gene mutations tat cause excessively high copper levels, particularly in the liver and brain.

Integrative systems‐level analysis reveals a contextual crosstalk between hypoxia and global metabolism in human breast tumors

open access: yesMolecular Oncology, EarlyView.
Breast tumor samples scored for metabolic deregulation (M1 to M3) were given a hypoxia score (HS). The highest HS occurred in patients with strongest metabolic deregulation (M3), supporting tumor aggressiveness. HS correlated with the highest number of metabolic pathways in M1. This suggests hypoxia to be an early event in metabolic deregulation.

Molecular Hydrogen in Orion as Observed by the Far Ultraviolet Spectroscopic Explorer

open access: yes, 2005
Diffuse far-ultraviolet stellar emission scattered by dust grains has been observed in a region near the Orion Nebula. In addition to the scattered stellar continuum, emission and absorption features produced by molecular hydrogen have been identified ...

Combinatorial Variations on Cantor's Diagonal [PDF]

open access: yes, 2011
We discuss counting problems linked to finite versions of Cantor's diagonal of infinite tableaux. We extend previous results of [2] by refining an equivalence relation that reduces significantly the exhaustive generation.

Is the Sykes – Picot Agreement of 1916 was the basis for the political division of the Middle East?

open access: yesJournal of Geography, Politics and Society, 2016
In 1916, Britain and France signed an agreement deals with the future division of the Ottoman Empire. This agreement, known as the Sykes – Picot Agreement, after its two designers, the British Sir Mark Sykes and the French François George Picot, is seen ...

Microwave probes Dipole Blockade and van der Waals Forces in a Cold Rydberg Gas [PDF]

open access: yesarXiv, 2015
We show that microwave spectroscopy of a dense Rydberg gas trapped on a superconducting atom chip in the dipole blockade regime reveals directly the dipole-dipole many-body interaction energy spectrum. We use this method to investigate the expansion of the Rydberg cloud under the effect of repulsive van der Waals forces and the breakdown of the frozen ...

MET variants with activating N‐lobe mutations identified in hereditary papillary renal cell carcinomas still require ligand stimulation

open access: yesMolecular Oncology, EarlyView.
MET variants in the N‐lobe of the kinase domain, found in hereditary papillary renal cell carcinoma, require ligand stimulation to promote cell transformation, in contrast to other RTK variants. This suggests that HGF expression in the microenvironment is important for tumor growth in such patients. Their sensitivity to MET inhibitors opens the way for
