PROTEKER: a near-shore submarine observatory in the Kerguelen Islands for the long-term monitoring of benthic habitats

Thomas Saucède
PROTEKER is a pilot program that aims at establishing a baseline for assessing the impact of climate change on near-shore marine ecosystems of the Kerguelen Islands by implementing an ecological and genetic monitoring at reference sites. The high diversity of coastal marine ecosystems is usually strongly impacted by environmental changes over the planet. In the Kerguelen Islands, such environments have been little investigated compared to open sea areas, and are still poorly known. The present...

Wetland functionning and functional traits of Nuphar lutea

Gudrun Bornette & Charles Henriot
Eleven populations of Nuphar lutea were sampled in eleven wetlands differing in physicochemical characteristics and spread along three rivers (the Ain, the Doubs and the Loue Rivers). Fifteen traits, grouped into four sets (growth, reproduction, storage and defence), were measured during the growing season. Most N. lutea traits were related to the environmental characteristics of wetlands.

Wikipedia Ranking of World Universities 2017

José Lages, Dima Shepelyansky & Célestin Coquidé
We present Wikipedia Ranking of World Universities (WRWU) based on analysis of networks of 24 Wikipedia editions collected in May 2017. With PageRank and CheiRank algorithms we determine ranking of universities averaged over cultural views of these editions. The comparison with the Shanghai ranking gives overlap of 60% for top 100 universities showing that WRWU gives more significance to their historical development. We show that the new reduced Google matrix algorithm allows to determine interactions...

Massive evaluation and analysis of Poincaré recurrences

Ivan Shevchenko, Guillaume Rollin, Alexander Melnikov & José Lages
We present a novel numerical method aimed to characterize global behaviour, in particular chaotic diffusion, in dynamical systems. It is based on an analysis of the Poincaré recurrence statistics on massive grids of initial data or values of parameters. We concentrate on Hamiltonian systems, featuring the method separately for the cases of bounded and non-bounded phase spaces. The embodiments of the method in each of the cases are specific. We compare the performances of the...

Wolfgang Ludwig, Philippe Amiotte Suchet & Jean-Luc Probst
Estimates for the riverine export of carbon and of sediments: dissolved organic carbon (DOC) export, particulate organic carbon (POC) export, bicarbonate export, export of bicarbonate being of atmospheric origin (atmospheric CO2 consumption by rock weathering), and sediment export. Estimates are based on empirical models for the overall continental area in a spatial resolution of 0.5 x 0.5 degree longitude/ latitude. .

Crystal structure of tricarbon­yl([mu]-di­phenyl­phosphido-[kappa]2P:P)(methyl­diphenyl­silyl-[kappa]Si)bis(tri­phenyl­phosphane-[kappa]P)iron(II)platinum(0)(Fe-Pt)

Michael Knorr, Isabelle Jourdain, Marek M. Kubicki, Ahmed Said Mohamed & Yoann Rousselin
The title compound, [FePt(C12H10P)(C13H13Si)(C18H15P)2(CO)3]·0.5CH2Cl2, represents an example of a phosphido-bridged heterobimetallic silyl complex; these are inter­esting precursors for the coordination and activation of small unsaturated organic mol­ecules. The [mu]2-PPh2 ligand spans the iron and platinum atoms, which are connected via a metal-metal bond of 2.7738 (4) Å. In contrast to most other complexes of the [(OC)3Fe(SiR3)([mu]-PR2)PtL2] family, where the iron-bound SiR3 group is trans-arranged with respect to the [mu]2-PPh2 ligand, the SiPh2Me ligand is roughly...

Reactivity of CuI and CuBr toward Dialkyl Sulfides RSR: From Discrete Molecular Cu4I4S4 and Cu8I8S6 Clusters to Luminescent Copper(I) Coordination Polymers

Michael Knorr, Carsten Strohmann, Abderrahim Khatyr, Marek M. Kubicki, Antony Lapprand, Yoann Rousselin, Antoine Bonnot & Pierre D. Harvey
The CuX salts (X = I, Br) react with SR2 to form molecular clusters of the types [(R2S)4(Cu4I4)] and [(R2S)6(Cu8I8)] or to give 1D polymers and 2D metal−organic frameworks. The cluster nuclearity and connectivity as well as the dimensionality of these compounds depend on the steric demand of SR2, the solvent polarity, and the nature of the halide. These materials have been characterized by X-ray and thermogravimetric analysis and steady-state and time-resolved absorption and emission...

Abderrahim Khatyr, Marek M. Kubicki, Michael Knorr, Yoann Rousselin, Marwa Chaabene & Mohedinne Askri
The novel 1D coordination polymer (CP) [{Cu(μ2-Br)2Cu}(μ-L2)2] CP2 has been obtained by reaction of the tetrakisthioether p-MeSC6H4SCH2SC6H4SMe-p (L2) with CuBr in a 1:2 metal-to ligand ratio. In contrast to the previously described CP [{Cu(μ2-Br)2Cu}(μ-L1)2] CP1 obtained by reaction of the tetrakisthioether p-MeOC6H4SCH2SC6H4OMe-p (L1) with CuBr, the two independent extended 1D ribbons contain bent Cu(μ2-Br)2Cu units of the butterfly-type with short Cu…Cu separations of 2.679(1) and 2.613(1) Å. In contrast to the common planar rhomboid Cu(μ2-Br)2Cu...

Googlomics: Inferring hidden causal relations between pathway members using reduced Google matrix of directed biological networks

José Lages, Dima Shepelyansky & Andrei Zinovyev
Signaling pathways represent parts of the global biological network which connects them into a seamless whole through complex direct and indirect (hidden) crosstalk whose structure can change during normal development or in a pathological conditions such as cancer. Advanced methods for characterizing the structure of the global directed causal network can shed light on the mechanisms of global cell reprogramming changing the distribution of possible signaling flows. We suggest a methodology, called Googlomics, for the...

4,4-Bis(4-methyl­phenyl­sulfan­yl)-1,1-diphenyl-2-aza­buta-1,3-diene

Michael Knorr, Hamid Boudiba, Rodolphe Kinghat, Abderrahim Khatyr & Marek M. Kubicki
In the title compound, C29H25NS2, both the Cl atoms of the aza­diene precursor 4,4-dichloro-1,1-diphenyl-2-aza­buta-1,3-diene are replaced by two vicinal S-p-tolyl substituents attached to the terminal C atom of a [pi]-conjugated 2-aza­butadiene array. The aza­diene chain is planar to within 0.01 Å. One of the phenyl rings seems to be slightly [pi]-conjugated with the aza­diene core [dihedral angle 5.1 (2)°].

Crystal structure of 4,4-di­bromo-1-(3,4-di­meth­­oxy­phen­yl)-2-aza­buta-1,3-diene-1-carbo­nitrile

Michael Knorr, Marwa Chaabene, Marek M. Kubicki, Abderrahim Khatyr, Mohedinne Askri & Yoann Rousselin
The title compound, C12H10Br2N2O2, represents an example of a planar π-con­jugated 2-aza­butadiene mol­ecule, which is both an inter­esting starting material for further organic transformations and a potential ligand in organometallic coordination chemistry. Its metric mol­ecular parameters are typical for the family of 2-aza­buta-1,3-dienes not substituted at the (CH) 3-position. In the crystal, the almost planar (r.m.s. deviation = 0.0658 Å) aza­diene mol­ecules form one-dimensional double-wide ribbons through inter­molecular halogen bonds (C—Br⋯O and C—Br⋯Br—C), which then stack...
