Nantes â Ăglise Saint-Jacques
Lâobservation archĂ©ologique dâune tranchĂ©e de rĂ©seau au chevet de lâĂ©glise Saint-Jacques de Pirmil, sur la rive sud de la Loire, a permis lâĂ©tude de deux sĂ©pultures mĂ©diĂ©vales liĂ©es au prieurĂ© bĂ©nĂ©dictin fondĂ© au xiie s. Lâanalyse de la stratigraphie montre que le cimetiĂšre situĂ© contre lâabside a subi un important terrassement entraĂźnant la destruction des derniers niveaux dâinhumation. Le mobilier mis au jour (cĂ©ramiques funĂ©raires) atteste de la vocation funĂ©raire de cet espace dĂšs le xiie..
Nantes â AllĂ©e Flesselles, allĂ©e de la Tremperie, rue de la Paix, place du Bouffay
Le suivi archĂ©ologique de la rĂ©novation des rĂ©seaux dâassainissement consĂ©cutive au rĂ©amĂ©nagement de lâespace public dans le secteur de la place du Bouffay et le long de lâancien quai de Loire a permis au cours de lâannĂ©e 2010 plusieurs observations ponctuelles sur le front sud de lâenceinte urbaine mĂ©diĂ©vale (xiiie-xve s.). Lieu privilĂ©giĂ© des relations entre la ville et le fleuve, espace-clef au dĂ©bouchĂ© de la ligne de pont situĂ© entre le chĂąteau comtal Ă lâouest (fin du xe s.) et le chĂątea..
Nantes â Place du Bouffay, allĂ©e Port-Maillard
Le prĂ©sent diagnostic ne forme quâune Ă©tape dâune Ă©tude archĂ©ologique plus vaste qui a concernĂ© en 2010-2012 la place du Bouffay, lâĂźlot Neptune et les anciens quais de Loire. Câest ainsi 3 opĂ©rations qui ont Ă©tĂ© menĂ©e par la ville de Nantes et lâInrap dans ce secteur au cĆur du centre ancien, jouxtant le front sud de lâenceinte de rĂ©union xiiie-xve s., et lieu privilĂ©giĂ© des relations entre la ville et le fleuve. SituĂ© au dĂ©bouchĂ© de la ligne de pont (porte de la Poissonnerie) et accueillant..
Nantes â 2 rue Portail
Lâanalyse archĂ©ologique dâune façade dâimmeuble au 2 rue Portail et situĂ©e sur lâemprise de lâancienne collĂ©giale Notre-Dame constitue une opportunitĂ© unique dâobservation directe de cet Ă©difice majeur de la citĂ© nantaise, aujourdâhui totalement disparu du paysage urbain. Ătabli Ă moins de cent mĂštres Ă lâouest de la cathĂ©drale, sur un terrain jouxtant intra-muros le front nord du castrum du Bas-Empire puis situĂ© Ă lâangle nord-ouest du castrum Ă©piscopal carolingien, le site de la future coll..
Nantes â Place Sainte-Croix
Le diagnostic rĂ©alisĂ© sur lâemprise du projet dâamĂ©nagement paysager du passage Sainte-Croix a surtout permis de vĂ©rifier que celui-ci ne menaçait pas les vestiges archĂ©ologiques rencontrĂ©s, particuliĂšrement les sĂ©pultures du cimetiĂšre mĂ©diĂ©val et/ou moderne. Le jardin objet du projet, jouxtant lâĂ©glise Sainte-Croix Ă lâouest, est situĂ© au cĆur du centre historique de Nantes (quartier du Bouffay). Ce jardin correspond au cloĂźtre prieural visible sur les plans du xviie s. Une Ă©tude documentair..
Nantes â ThĂ©Ăątre Grand T, 84 rue du GĂ©nĂ©ral-Buat
Ce diagnostic, rĂ©alisĂ© le long dâun axe viaire antique majeur (voie Nantes-Angers), aux marges orientales de la ville antique et mĂ©diĂ©vale, a permis, malgrĂ© des conditions hydrologiques difficiles, lâidentification de deux occupations chronologiquement et spatialement bien distinctes (fig. 1). Au nord de lâemprise, câest le parcellaire et les espaces de jardins en lien avec le bĂąti civil, qui sâimplante et se dĂ©veloppe en front de rue dans le cours des xixe s. et xxe s., qui a pu ĂȘtre mis en ..
Liouville field theory coupled to a critical Ising model: Non-perturbative analysis, duality and applications
Two different kinds of interactions between a -parafermionic and a
Liouville field theory are considered. For generic values of , the effective
central charges describing the UV behavior of both models are calculated in the
Neveu-Schwarz sector. For exact vacuum expectation values of primary
fields of the Liouville field theory, as well as the first descendent fields
are proposed. For , known results for Sinh-Gordon and Bullough-Dodd models
are recovered whereas for , exact results for these two integrable coupled
Ising-Liouville models are shown to exchange under a weak-strong coupling
duality relation. In particular, exact relations between the parameters in the
actions and the mass of the particles are obtained. At specific imaginary
values of the coupling and , we use previous results to obtain exact
information about: (a) Integrable coupled models like Ising-,
homogeneous sine-Gordon model or the Ising-XY model; (b)
Neveu-Schwarz sector of the integrable perturbation of N=1
supersymmetric minimal models. Several non-perturbative checks are done, which
support the exact results.Comment: 29 pages, 1 fig., LaTeX file with epsfig, amssymb, 3 references

Prioritization of candidate causal genes for asthma in susceptibility loci derived from UK Biobank
Kim Valette et al. perform a genomic study on asthma integrating genome-wide association study, functional mapping using lung and blood transcriptome-wide profiles, as well as Mendelian randomization. They show candidate causal genes expressed in lung and blood tissues that are putative therapeutic targets for asthma
Gammapy: A Python package for gamma-ray astronomy
In this article, we present Gammapy, an open-source Python package for the
analysis of astronomical -ray data, and illustrate the functionalities
of its first long-term-support release, version 1.0. Built on the modern Python
scientific ecosystem, Gammapy provides a uniform platform for reducing and
modeling data from different -ray instruments for many analysis
scenarios. Gammapy complies with several well-established data conventions in
high-energy astrophysics, providing serialized data products that are
interoperable with other software packages. Starting from event lists and
instrument response functions, Gammapy provides functionalities to reduce these
data by binning them in energy and sky coordinates. Several techniques for
background estimation are implemented in the package to handle the residual
hadronic background affecting -ray instruments. After the data are
binned, the flux and morphology of one or more -ray sources can be
estimated using Poisson maximum likelihood fitting and assuming a variety of
spectral, temporal, and spatial models. Estimation of flux points, likelihood
profiles, and light curves is also supported. After describing the structure of
the package, we show, using publicly available -ray data, the
capabilities of Gammapy in multiple traditional and novel -ray analysis
scenarios, such as spectral and spectro-morphological modeling and estimations
of a spectral energy distribution and a light curve. Its flexibility and power
are displayed in a final multi-instrument example, where datasets from
different instruments, at different stages of data reduction, are
simultaneously fitted with an astrophysical flux model.Comment: 26 pages, 16 figure
