Extraire des patterns pour améliorer l'idiomaticité de résumés semiautomatiques en finances : le cas du lexique support
2020
International audience; Cet article présente des travaux visant à développer un système de rédaction automatique de résumés de textes économiques et financiers en attachant une attention particulière à l’idiomaticité et à la fluidité de la langue d’arrivée. Pour ce faire, l’étude part d’un corpus de rapports périodiques de la Banque de France relevant des discours de conjoncture. Le travail linguistique permet de montrer qu’une rédaction des résumés ne s’attachant qu’à l’extraction terminologique et collocationnelle stricte ignore tout un pan de vocabulaire, saisi ici comme « lexique support », jouant un rôle important dans l’organisation cognitive du domaine. Sur cette base, le travail pré…
A molecular study of Neophyllaphis varicolor (Hemiptera, Aphididae) in Costa Rica
2019
The genus Neophyllaphis (Takahashi) (Aphididae: Neophyllaphidinae) is composed of 18 species; however, in the Americas only nine species have been reported previously. A new species, Neophyllaphis varicolor Miller & Halbert, was described in 2014 in USA. Colonies resembling those of this new species have been observed in Costa Rica on Podocarpus spp. In order to determine if N. varicolor is also present in Costa Rica, we sampled Neophyllaphis colonies from Podocarpus falcatus and P. chinensis. Additionally, we sampled individuals from Podocarpus sp. in Spain and Vietnam. DNA of each sample was extracted and used to amplify and sequence the cytochrome c oxidase subunit I (COI) and elongation…
Revisiting the Nordic long-term care model for older people - still equal?
2022
With the extensive long-term care services for older people, the Nordic countries have been labelled ‘caring states’ as reported (Leira, Welfare state and working mothers: the Scandinavian experience, Cambridge University Press, Cambridge, 1992). The emphasis on services and not cash benefits ensures the Nordics a central place in the public service model (Anttonen and Sipilä, J Eur Soc Policy 6:87–100, 1996). The main feature of this ideal model is public social care services, such as home care and residential care services, which can cover the need for personal and medical care, as well as assistance with household chores. These services are provided within a formally and professionally b…
Polimorfismo del gene ACE:gene della longevità o fattore di rischio nella patologia ipertensiva
2012
Negli ultimi decenni l’allungamento della vita media ha stimolato un particolare interesse nello studio dei processi dell’invecchiamento e nella ricerca di possibili geni coinvolti nella longevità. In particolare i centenari dimostrano di avere una prevalenza minore di malattie cardiovascolari e dei fattori di rischio ad essa correlati. L’enzima di conversione dell’angiotensina (ACE), presente in tutte le cellule endoteliali, gioca un ruolo essenziale nel mantenimento dell’omeostasi del flusso vascolare, regolando sia la produzione del vasocostrittore angiotensina II sia inattivando la bradichinina. In particolare alcuni studi hanno riportato una possibile correlazione tra il polimorfismo I…

Characteristics of current roadside pollution using test-monitoring plots
2014
Abstract The aim of the study was the qualitative recognition of the existing roadside pollutants deposited in topsoils located close to roads with high traffic volume. So far, the studies have helped to determine the content of pollutants that accumulated over a long period of time. Traditionally, it has been difficult to distinguish between roadside pollution and pollution from other industrial sources. In order to avoid such problems and to accurately recognize present threats originating from road traffic, test-monitoring plots were installed in Poland (Gliwice and Opole), Germany (Tubingen, Ulm and Boblingen), Finland (Helsinki), Tajikistan (Dushanbe) and China (Lanzhou). To install th…
Finely tuned nickel complexes as highly active catalysts affording branched polyethylene of high molecular weight: 1-(2,6-Dibenzhydryl-4- methoxyphen…
2018
Abstract A series of unsymmetrical 1,2-bis(imino)acenaphthenenickel(II) halides containing N-2,6-dibenzhydryl-4-methoxyphenyl – a single bulky group with adjusted electron donating properties – has been synthesized and characterized. These compounds adopt distorted tetrahedral geometry and their 1H NMR spectra show the paramagnetically shifted peaks. On activation with a low amount of Et2AlCl or ethylaluminum sesquichloride (EASC), these nickel complexes display high activity in ethylene polymerization, yielding the polyethylene of high molecular weight. They are also stable at elevated temperature; superb activity of 2.51 × 106 g of PE (mol of Ni)−1 h−1 can be attained at 90 °C. The result…
A Study on the Propagation of Plane Stress Waves across the Thickness of a Plate by the Method of Analytic Continuation in Time
2004
The interaction of plane tension/compression waves propagating within a plate perpendicularly to its surface is considered. The analytic solution is obtained by a modified method of characteristics for the one-dimensional wave equation used in problems on an impact of a rigid body on the surface of a plate. The displacements, velocities, and stresses in the plate are determined by the edge disturbance caused by the initial velocity and the stationary force field of masses of the striker and the plate. The method of analytic continuation in time put forward allows a stress analysis for an arbitrary time interval by using finite expressions. Contrary to a stress analysis in the frequency doma…
Symbolic Worst Case Execution Times
2011
In immediate or hard real-time systems the correctness of an operation depends not only upon its logical correctness, but also on the time in which it is computed. In such systems, it is imperative that operations are performed within a given deadline because missing this deadline constitutes the failure of the complete system. Such systems include medical systems, flight control systems and other systems whose failure in responding punctually results in a high economical loss or even in the loss of human lives. These systems are usually analyzed in a sequence of steps in which first, a socalled control flow graph (CFG) is constructed that represents possible program flows. Furthermore, bou…
Processing-property relationships of polypropylene/ciprofloxacin fibers
2015
In this work we prepared polypropylene (PP) fibers incorporating an antibiotic, i.e. ciprofloxacin (CFX), by melt spinning. In particular, PP has been compounded with CFX at different concentrations by using a counter-rotating twin screw compounder. The PP/CFX fibers have been spun by using a capillary rheometer operating under a constant extrusion speed. The effect of “online” hot drawing during the melt spinning or of an “offline” cold drawing on the properties of PP/CFX fibers were evaluated. In particular, the influence of the drawing conditions on the mechanical properties and the release kinetics were studied. Moreover, the rheological behavior in non-isothermal elongation flow has be…
