Consensus standards for acquisition, measurement, and reporting of intravascular optical coherence tomography studies

Objectives: The purpose of this document is to make the output of the International Working Group for Intravascular Optical Coherence Tomography (IWG-IVOCT) Standardization and Validation available to medical and scientific communities, through a peer-reviewed publication, in the interest of improving the diagnosis and treatment of patients with atherosclerosis, including coronary artery disease. Background: Intravascular optical coherence tomography (IVOCT) is a catheter-based modality that acquires images at a resolution of ∼10 μm, enabling visualization of blood vessel wall microstructure in vivo at an unprecedented level of detail. IVOCT devices are now commercially available worldwide, there is an active user base, and the interest in using this technology is growing. Incorporation of IVOCT in research and daily clinical practice can be facilitated by the development of uniform terminology and consensus-based standards on use of the technology, interpretation of the images, and reporting of IVOCT results. Methods: The IWG-IVOCT, comprising more than 260 academic and industry members from Asia, Europe, and the United States, formed in 2008 and convened on the topic of IVOCT standardization through a series of 9 national and international meetings. Results: Knowledge and recommendations from this group on key areas within the IVOCT field were assembled to generate this consensus document, authored by the Writing Committee, composed of academicians who have participated in meetings and/or writing of the text. Conclusions: This document may be broadly used as a standard reference regarding the current state of the IVOCT imaging modality, intended for researchers and clinicians who use IVOCT and analyze IVOCT data

SOUFFLERIES À JETS DE PLASMAS RAREFIÉS

Plasmas jets are studied at low pressure (10-1 - 10 torr) and high temperature (2000 K - 8000 K) to simulate a lot of parameters of re-entry plasma. The experimental apparatus is described and the used diagnostic techniques as electrostatic probes, mass spectrometer, MHD and optical spectrometer are presented. The obtained plasmas are modelized with a two-temperature model (electron temperature and heavy particule temperature).Des jets de plasma sont étudiés à basse pression (10-1 - 10 torr) et à haute température (2000-8000 K) pour simuler certains paramètres caractérisant le plasma de ré-entrée d'un engin dans la zone atmosphérique. L'ensemble expérimental est décrit et les méthodes de diagnostic telles que les sondes électrostatiques, le spectromètre de masse, la MHD et la spectroscopie optique d'émission sont présentées. Les plasmas obtenus expérimentalement sont modélisés en utilisant une approche à deux températures (température électronique et température des espèces lourdes)

Assessing job candidates’ creativity: Propositions and future research directions

Identifying and selecting creative employees is of key importance in today's high-pace business environment. Yet, little is known about how assessors in organizational settings evaluate the creative potential of job candidates. In this paper we review the extant literature on individual and team creativity in order to identify criteria (cues) against which job candidates' creativity could be assessed. We argue that the creative potential of job candidates could be evaluated against four key dimensions (the creative individual, the creative product, the creative process and the creative environment) and call for empirical research to further explore and test our propositions in practice
