Gaia Data Release 1

Gaia Data Processing & Céline Reylé
Gaia is a cornerstone mission in the science programme of the European Space Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was changed to a direct-imaging approach. Both the spacecraft and the payload were built by European industry. The involvement of the scientific community focusses on data processing for which the international Gaia Data Processing and Analysis Consortium (DPAC) was selected in 2007. Gaia was...

In the title compound, C20H16Br4, both vinylic substituents were introduced by a Corey-Fuchs reaction using 4,12-diform­yl[2.2]paracyclo­phane as starting material. The title compound may be used as a valuable precursor for the synthesis of diethyn­yl[2.2]paracyclo­phane. The title mol­ecule is centrosymmetric with a crystallographic center of inversion between the centers of the two phenyl rings. A strong tilting is observed with an inter­planar angle between the best aromatic plane and the vinyl plane of 49.4 (5)°. No...

Crystal structure of di-[mu]-iodido-bis­[bis(aceto­nitrile-[kappa]N)copper(I)]

Michael Knorr, Eva Rebecca Barth, Christopher Golz & Carsten Strohmann
The title compound, [Cu2I2(CH3CN)4], exhibits a centrosymmetric Cu2I2 core [Cu...Cu distance = 2.7482 (11) Å], the CuI atoms of which are further coordinated by four mol­ecules of aceto­nitrile. The CuI atom has an overall distorted tetra­hedral coordination environment evidenced by L-Cu-L angles (L = N or I) ranging from 100.47 (10) to 117.06 (2)°. The coordination geometries of the aceto­nitrile ligands deviate slightly from linearity as shown by Cu-N-C angles of 167.0 (2) and 172.7...

Bis{(4-methylthio)phenylthio}methane as assembling ligand for the construction of Cu(I) and Hg(II) coordination polymers. Crystal structures and topological (AIM) analysis of the bonding

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...

EWET : EmsB Website for Echinococcus Typing

Jenny Knapp
The EWET database (EWET-DB) contains genotyping data on the parasite Echinococcus multilocularis, obtained after the analysis of the microsatellite EmsB. A set of information is also avaible on the sampled parasite isolates (host, geographical position, sampling conditions, laboratory of reference, etc.). A web interface provides access to all or part of the data set, perform distance calculation, obtain maps and give new genotyping.

Diethyl 2,2'-(1,4-phenyl­enedi­oxy)­diacetate

Michael Knorr, Jérôme Husson, Yoann Rousselin & Marek M. Kubicki
In the title compound, C14H18O6, a crystallographic center at the centroid of the aromatic ring generates the complete mol­ecule which is planar within 0.085 (1) Å for the non-H atoms. In the crystal, weak C—H⋯O and C—H⋯π inter­actions link the molecules.

Wikipedia network analysis of cancer interactions and world influence

José Lages, Dima Shepelyansky & Guillaume Rollin
We apply the Google matrix algorithms for analysis of interactions and influence of 37 cancer types, 203 cancer drugs and 195 world countries using the network of 5 416 537 English Wikipedia articles with all their directed hyperlinks. The PageRank algorithm provides the importance order of cancers which has 60% and 70% overlaps with the top 10 cancers extracted from World Health Organization GLOBOCAN 2018 and Global Burden of Diseases Study 2017, respectively. The recently...

BIOTROPH - Molecular Ecology

Shinji Ozaki, Francis Raoul, Renaud Scheifler, Clémentine Fritsch, Benoit Valot, Frédéric Mora & Thierry Cornier
A data set for the project ‘BIOTROPH’. The aim of this study was to estimate functional role of the taxonomic diversity of available resources in the field on trophic exposure of small mammals (wood mice ‘Apodemus sylvaticus’) to trace metals (TM; principally cadmium, lead and zinc). The data was composed of (i) TM concentration in soils around the traps for capturing rodents (data from another project ‘STARTT’); (ii) captured wood mice; (iii) diet of wood...

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.

Crystal structure of di-[mu]-iodido-bis­[(dimethyl sulfoxide-[kappa]O)(tri­phenyl­phosphane-[kappa]P)copper(I)]

Michael Knorr, Rodolphe Kinghat, Marek M. Kubicki & Yoann Rousselin
The centrosymmetric dinuclear title compound, [Cu2I2(C2H6OS)2(C18H15P)2], represents the first example of a CuI complex ligated by an O-bound dimethyl sulfoxide ligand. In the crystal, the two tetrahedrally coordinated CuI atoms are bridged by two [mu]2-iodido ligands in an almost symmetrical rhomboid geometry. The loose Cu...Cu contact of 2.9874 (8) Å is longer than the sum of the van der Waals radii of two Cu atoms (2.8 Å), excluding a significant cupriophilic inter­action in the actual...

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...

Water sanctuaries in Eastern Gaul : origin, organization and evolution from first century B.C to fourth century A.D

Damien Vurpillot
Les sanctuaires des eaux forment une catégorie originale de lieux de culte antiques, en particulier en Gaule où une place privilégiée leur est traditionnellement accordée dans le paysage religieux. Une spécificité largement surexploitée et surinterprétée par une abondante littérature qui a contribué à véhiculer une vision faussée du phénomène. La reprise récente de données sur une série de sites considérés comme caractéristiques, et s’appuyant sur plusieurs projets de recherches, rend opportune la mise en œuvre...

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...

Calculated spectroscopic line lists for methane, resulting from the most recent high-resolution experimental spectrum assignments and fits.


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)°].
