The wide-field imager for IXO: status and future activities
2010
The Wide Field Imager (WFI) of the International X-ray Observatory (IXO) is an X-ray imaging spectrometer based on a large monolithic DePFET (Depleted P-channel Field Effect Transistor) Active Pixel Sensor. Filling an area of 10 x 10 cm2 with a format of 1024 x 1024 pixels it will cover a field of view of 18 arcmin. The pixel size of 100 x 100 μm2 corresponds to a fivefold oversampling of the telescope's expected 5 arcsec point spread function. The WFI's basic DePFET structure combines the functionalities of sensor and integrated amplifier with nearly Fano-limited energy resolution and high efficiency from 100 eV to 15 keV. The development of dedicated control and amplifier ASICs allows for…

Systematic reproduction and distribution, duplication of any material in this paper for a fee or for commercial purposes, or modification of the content of the paper are prohibited. The Wide Field Imager (WFI) is one of the two instruments of the ATHENA astrophysics space mission approved by ESA as the second large mission in the Cosmic Vision 2015-2025 Science Programme. The WFI, based on a large array of depleted field effect transistors (DEPFET), will provide imaging in the 0.2-15 keV band over a 40'x40' field of view, simultaneously with spectrally an…
The LOFT mission concept: a status update
2016
The Large Observatory For x-ray Timing (LOFT) is a mission concept which was proposed to ESA as M3 and M4 candidate in the framework of the Cosmic Vision 2015-2025 program. Thanks to the unprecedented combination of effective area and spectral resolution of its main instrument and the uniquely large field of view of its wide field monitor, LOFT will be able to study the behaviour of matter in extreme conditions such as the strong gravitational field in the innermost regions close to black holes and neutron stars and the supra-nuclear densities in the interiors of neutron stars. The science payload is based on a Large Area Detector (LAD, >8m2 effective area, 2-30 keV, 240 eV spectral resolut…
Amerikāņu un meksikāņu viedoklis par „amerikāņu sapni”
2017
Bakalaura darba tēma ir uzzināt Amerikāņu un Meksikāņu viedokļus par "Amerikāņu sapni", kuri atspoguļojas filmās, kā arī, to kā Amerikāņu sapnis ir uztverts filmās "Ziemeļi" (1984) un "Tiekšanās pēc laimes" (2006). Galvenais uzdevums bija analizēt filmas, lai redzētu kā Amerikāņu sapnis tiek panākts abām nācijām. Papildus, šim uzdevumam tika arī uzsvērti Amerikāņu sapņa elementi, kas raksturo šo fenomenu. Pētījumā viens no uzdevumiem bija atrast Amerikāņu sapnim pašu piemērotāko definīciju un elementus kas to veido. Tas tika paveikts lasot dažādu autoru grāmatas un rakstus, kuri diskutē par šo tēmu. Bakalaura darbā tika izmantotas pētīšanas metodes, tādas kā, bibliotēkas pētījumi un filmu, …
Evolutionary-based 3D reconstruction using an uncalibrated stereovision system: application of building a panoramic object view
2010
In this paper, we propose an original evolutionary-based method for 3D panoramic reconstruction from an uncalibrated stereovision system (USS). The USS is composed of five cameras located on an arc of a circle around the object to be analyzed. The main originality of this work concerns the process of the calculation of the 3D information. Actually, with our method, 3D coordinates are directly obtained without any prior estimation of the fundamental matrix. The method operates in two steps. Firstly, points of interest are detected in pairs of images acquired by two consecutive cameras of the USS are matched. And secondly, using evolutionary algorithms, we jointly compute the transformed matr…
Dacarbazine mediate antimelanoma effects via NK cells.
2013
International audience; Melanoma is a highly chemoresistant and metastatic tumor that, in the absence of BRAF mutations, is generally treated with the alkylating agent dacarbazine (DTIC). We discovered that DTIC upregulates the expression of NKG2D ligands on tumor cells, leading to the activation of natural killer (NK) and CD8(+) T cells. These observations underscore the immunogenic properties of DTIC and provide a rationale to combine DTIC with immunotherapeutic agents.
Du cadre littéraire de A Room with a View (E.M. Forster) à son décentrement cinématographique (James Ivory) : éléments de réflexion pour une esthétiq…
2010
International audience; Dans A Room with a View (1908), E. M. Forster multiplie les cadres topographiques afin d'opérer un « cadrage » de son intrigue et de son héroïne immédiatement signifiant. Par le motif de la fenêtre, les titres de chapitres, les commentaires du narrateur ou par la réification consécutive à la comparaison avec la peinture de Léonard de Vinci, le personnage de Lucy Honeychurch est à ce point encadré qu'il lui faut sortir de ces espaces textuels étouffants et revendiquer qu'il est surtout un corps vivant dans un espace mouvant. Une première dialectique entre ces trois termes souligne ainsi les ancrages principaux et les limites de l'écriture forstérienne, puisque la récu…
An overview of the concepts of change and development - from the premodern to modern era
2012
This chapter focuses on the concepts of change and progress: on one hand, it approaches this topic from the point of view of the history of science; on the other hand, from the point of view of modern developmental psychology. The section on the history of science focuses on the historical period of the pre-modern Hellenistic era to the Enlightenment. This period is long, and it therefore includes several, different world views and cultural trends. In this chapter culturally significant trends of thought within the PtolemaicAristotelic tradition are described.The section on the modern developmental psychology approach analyses the following questions: (1) which characteristics must changes …
Henkilön psykiatria : psykiatrian dialektinen filosofia
2017
The Finnish word ’henkilö’ is difficult to translate in English as a ‘Person’, but in international plan-language, Esperanto, we can quite exactly translate it as ‘spiritulo’. The word henkilö, spiritulo, is developed in the 19th century from the ancient Finnish word ‘henki’ by the medical doctor in Jyväskylä region Wolmar Schildt-Kilpinen. He was not satisfied with the simple translation from Latin word ‘persona’ to Finnish ‘persoona’, and so via the ancient word he conceptually combined the spiritulo to the dialectical process of negation of negation of the ethnic culture – elite culture – national culture. So the spiritulo could express the community (Gemeinschaft) and common (gemein) at…
