PHIBSS: Searching for Molecular Gas Outflows in Star-forming Galaxies at z = 0.5–2.6

We present an analysis of millimeter CO observations to search for and quantify signatures of molecular gas outflows. We exploit the large sample of 0.5 1.5 and available properties (stellar mass, star formation rate or SFR, size) from ancillary data. None of the individual spectra exhibit a compelling signature of CO outflow emission, even at high SNR > 7. To search for fainter outflow signatures, we carry out an analysis of stacked spectra, including the full sample, as well as subsets, split in terms of stellar mass, redshift, inclination, offset in SFR from the main sequence, and active galactic nuclei activity. None of the physically motivated subsamples shows any outflow signature. We report a tentative detection in a subset statistically designed to maximize outflow signatures. We derive upper limits on molecular gas outflow rate and mass loading factors eta based on our results and find eta <= 2.2-35.4, depending on the subsample. Much deeper CO data and observations of alternative tracers are needed to decisively constrain the importance of the cold molecular gas component of outflows relative to other gas phases

Contrasting styles of (U)HP rock exhumation along the Cenozoic Adria-Europe plate boundary (Western Alps, Calabria, Corsica)

Since the first discovery of ultrahigh pressure (UHP) rocks 30 years ago in the Western Alps, the mechanisms for exhumation of (U)HP terranes worldwide are still debated. In the western Mediterranean, the presently accepted model of synconvergent exhumation (e.g., the channel-flow model) is in conflict with parts of the geologic record. We synthesize regional geologic data and present alternative exhumation mechanisms that consider the role of divergence within subduction zones. These mechanisms, i.e., (i) the motion of the upper plate away from the trench and (ii) the rollback of the lower plate, are discussed in detail with particular reference to the Cenozoic Adria-Europe plate boundary, and along three different transects (Western Alps, Calabria-Sardinia, and Corsica-Northern Apennines). In the Western Alps, (U)HP rocks were exhumed from the greatest depth at the rear of the accretionary wedge during motion of the upper plate away from the trench. Exhumation was extremely fast, and associated with very low geothermal gradients. In Calabria, HP rocks were exhumed from shallower depths and at lower rates during rollback of the Adriatic plate, with repeated exhumation pulses progressively younging toward the foreland. Both mechanisms were active to create boundary divergence along the Corsica-Northern Apennines transect, where European southeastward subduction was progressively replaced along strike by Adriatic northwestward subduction. The tectonic scenario depicted for the Western Alps trench during Eocene exhumation of (U)HP rocks correlates well with present-day eastern Papua New Guinea, which is presented as a modern analog of the Paleogene Adria-Europe plate boundary

La question du diagnostic psychologique en clinique de la douleur

International audienceDuring his clinical activity in chronic pain department, the psychologist performs the functions of evaluation psychological and psychopathological diagnosis, that nobody else assumes. This process of tracking the places and functions of pain in the history and psychic organization of the patient in pain is essential for the care of the suffering body in a necessary somato-psychic round trip. However, the nosographical reorganization led to a renaming through which it may be hard to find one’s way. This confusion is also maintained by the medical care of the psychic symptomatology, when provided by “somatic” medicine. To make a diagnosis questions the place and purpose of the approach: how it settles inside the therapeutic relationship, which goal is adapted to what care, who is sharing this goal, who discusses it… a big amount of questions that maintain humility and make room for what can happen. Hence the diagnosis opens and does not closes, it helps to give meaning to what does not make sense, or not anymore. But the diagnosis also can sterilize thoughts and care if given with no preoccupation of its purpose and address. Thus, it would probably be more accurate to speak about a process of diagnosis, as it takes time to reach the registered painful trace, taking space in the internal space, and to get out of the “organicity” in which the patient settled down

Le Jurassique dauphinois entre Durance et Rhône : étude stratigraphique et géodynamique ; évolution d'une portion de la marge nord téthysienne (Alpes occidentales françaises)

La couverture des Massifs cristallins externes dauphinois et savoyards est minutieusement analysée à l'aide de toutes les données stratigraphiques, paléontologiques et paléotectoniques accumulées lors du lever des cartes géologiques au 50.000è. La complexité de la région est démontrée sur trois thèmes essentiels: - l'existence d'une tectonique au Lias (prouvée par de nombreux exemples de mise en plase d'olistolites) se traduit par le jeu de failles normales avec basculement saccadé de blocs de socle et cette phase distensive se poursuit jusque dans le Malm; la direction ou l'orientation des paléopentes est soit méridienne, soit transverse - les lignes paléogéographiques au Lias sont très obliques aux limites actuelles des massifs de socle et le nord de la zone dauphinoise a tendance à se raccorder à l'Est lyonnais et au Jura, tandis que le Sud appartient au bassin du Sud-Est avec des zones de haut-fonds mobiles; dès le Toarcien supérieur (après une phase de paroxysme tectonique) la paléogéographie acquiert une polarité est-ouest - l'importance de la tectonique alpine se vérifie par des écaillages de socle jalonnés de sutures sédimentaires avec déversements ou chevauchements vers l'Ouest mais aussi vers le Nord et par un resserrement très important des ensembles sédimentaires où les surfaces de dislocations tectoniques sont très difficiles à suivre.
