On Global Warming (Softening Global Constraints)
We describe soft versions of the global cardinality constraint and the
regular constraint, with efficient filtering algorithms maintaining domain
consistency. For both constraints, the softening is achieved by augmenting the
underlying graph. The softened constraints can be used to extend the
meta-constraint framework for over-constrained problems proposed by Petit,
Regin and Bessiere.Comment: 15 pages, 7 figures. Accepted at the 6th International Workshop on

Françoise Mengin, Fragments dâune guerre inachevĂ©e. Les entrepreneurs taiwanais et la partition de la Chine (Fragments of an unfinished war: Taiwanese entrepreneurs and Chinaâs partition)
Based on a highly detailed study of Taiwanese entrepreneurship from its origins to the present, this book seeks to examine Sino-Taiwanese discord, taking a political economy approach. In her introduction, Françoise Mengin rightly stresses that this dispute cannot be understood without âcombining social logics with that of conflict of sovereignty,â (p. 20) and without situating the inner workings of the movement in their historicity. One of the strength of this book is to have succeeded in thi..
DFT+U study of magnetic order in doped LaCuO crystals
This article presents the results of several magnetic phases of doped
LaSrCuO using density-functional theory with an added Hubbard
term (DFT+U). Doping factors from to 0.25 were examined. We found that a
bond centered stripe is the magnetic ground state for and . No
stable stripe order was found for . Analysis of the electron density
revealed that apical oxygen atoms, those located above and below the copper
atoms in the CuO planes, hold a non negligible part of the holes at large
doping and present a small spin polarization. Finally, the charge
reorganization caused by the magnetic stripe modulation was studied for bond
centered and atom centered stripes.Comment: 7 pages, 6 figures (submitted to PRB
Prefix-Projection Global Constraint for Sequential Pattern Mining
Sequential pattern mining under constraints is a challenging data mining
task. Many efficient ad hoc methods have been developed for mining sequential
patterns, but they are all suffering from a lack of genericity. Recent works
have investigated Constraint Programming (CP) methods, but they are not still
effective because of their encoding. In this paper, we propose a global
constraint based on the projected databases principle which remedies to this
drawback. Experiments show that our approach clearly outperforms CP approaches
and competes well with ad hoc methods on large datasets
Open science resources for the discovery and analysis of Tara Oceans data
Pesant, StĂ©phane ... et. al.-- 16 pages, 5 figures, 2 tables.-- This article is contribution number 26 of the Tara Oceans ConsortiumThe Tara Oceans expedition (2009â2013) sampled contrasting ecosystems of the world oceans, collecting environmental data and plankton, from viruses to metazoans, for later analysis using modern sequencing and state-of-the-art imaging technologies. It surveyed 210 ecosystems in 20 biogeographic provinces, collecting over 35,000 samples of seawater and plankton. The interpretation of such an extensive collection of samples in their ecological context requires means to explore, assess and access raw and validated data sets. To address this challenge, the Tara Oceans Consortium offers open science resources, including the use of open access archives for nucleotides (ENA) and for environmental, biogeochemical, taxonomic and morphological data (PANGAEA), and the development of on line discovery tools and collaborative annotation tools for sequences and images. Here, we present an overview of Tara Oceans Data, and we provide detailed registries (data sets) of all campaigns (from port-to-port), stations and sampling eventsWe thank the commitment of the following people and sponsors who made this singular expedition possible: CNRS (in particular the Groupement de Recherche GDR3280), European Molecular Biology Laboratory (EMBL), Genoscope/CEA, Fund for Scientific ResearchâFlanders, VIB, Stazione Zoologica Anton Dohrn, UNIMIB, ANR (projects POSEIDON/ANR-09-BLAN-0348, BIOMARKS/ANR-08-BDVA- 003, PROMETHEUS/ANR-09-GENM-031, PROMETHEUS/ANR-09-PCS-GENM-217, TARAGIRUS/ANR-09-PCS-GENM-218, OCEANOMICS/ANR-11-BTBR-0008, FRANCE GENOMIQUE/ANR-10-INBS-09-08), EU FP7 (MicroB3/No.287589, IHMS/HEALTH-F4-2010-261376, MetaCardis/HEALTH-F4-2012-305312), ERC Advanced Grant Awards to CB (Diatomite: 294823) and PB (CancerBiome: 268985), Spanish Ministry of Science and Innovation grant CGL2011-26848/BOS MicroOcean PANGENOMICS to SGA, JSPS KAKENHI Grant Number 26430184 to HO, FWO, BIO5, Biosphere 2, agne`s b., the Veolia Environment Foundation, Region Bretagne, World Courier, Illumina, Cap LâOrient, the EDF Foundation EDF Diversiterre, FRB, the Prince Albert II de Monaco Foundation, Etienne Bourgois, the Tara schooner and its captain and crew.
