Seizure detection algorithm for neonates based on wave-sequence analysis

Objective: The description and evaluation of the performance of a new real-time seizure detection algorithm in the newborn infant. Methods: The algorithm includes parallel fragmentation of EEG signal into waves; wave-feature extraction and averaging; elementary, preliminary and final detection. The algorithm detects EEG waves with heightened regularity, using wave intervals, amplitudes and shapes. The performance of the algorithm was assessed with the use of event-based and liberal and conservative time-based approaches and compared with the performance of Gotman's and Liu's algorithms. Results: The algorithm was assessed on multi-channel EEG records of 55 neonates including 17 with seizures. The algorithm showed sensitivities ranging 83-95% with positive predictive values (PPV) 48-77%. There were 2.0 false positive detections per hour. In comparison, Gotman's algorithm (with 30 s gap-closing procedure) displayed sensitivities of 45-88% and PPV 29-56%; with 7.4 false positives per hour and Liu's algorithm displayed sensitivities of 96-99%, and PPV 10-25%; with 15.7 false positives per hour. Conclusions: The wave-sequence analysis based algorithm displayed higher sensitivity, higher PPV and a substantially lower level of false positives than two previously published algorithms. Significance: The proposed algorithm provides a basis for major improvements in neonatal seizure detection and monitoring.

Une façon d’indiquer la «non-coïncidence entre les mots et les choses», on va dire…

Nous souhaitons nous pencher ici sur un emploi particulier de la périphrase en aller + infinitif qui n’a fait l’objet – à notre connaissance – que d’un article (Lansari 2010). Cet emploi « modalisant » que Lansari limite à la formule 'on va dire' mériterait d’être approfondi pour plusieurs raisons. D’une part, l’emploi n’est décrit que sur base de « vingt exemples tirés d’internet, de blogs ou de forums » (Lansari 2010: 120) alors que, de l’aveu de Lansari elle-même, l’emploi relève de l’oral. Il serait donc utile d’enrichir – quantitativement et qualitativement - le corpus et d’y intégrer des occurrences d’oral authentique. D’autre part, Lansari restreint l’emploi modalisant à la séquence 'on va dire' ; on pourrait s’interroger sur la capacité de séquences comme 'je vais dire' à remplir les mêmes fonctions discursives. Dans cet article, nous commencerons par un – forcément bref – état de la question. Après avoir présenté le corpus, nous testerons les hypothèses précédemment défendues à la lueur du corpus rassemblé: (a) Le corpus CFPP2000 issu du projet Discours sur la ville. Corpus de Français Parlé Parisien des années 2000 (disponible en ligne à http://cfpp2000.univ-paris3.fr/Corpus.html). CFPP2000 donne la parole à 41 informateurs en 28 interviews (2198 min) et a généré 96 occurrences de on va dire modalisant. (b) Le corpus CLAPI comprenant 45 heures d’interactions interrogeables en ligne à http://clapi.univ-lyon2.fr/analyse_requete_aide.php?menu=outils. On y a relevé 12 exemples de on va dire modalisant. (c) Un corpus personnel d’interviews (163min) réalisées pendant l’année académique 2009-10 auprès de cinq étudiants Erasmus français grâce au soutien d’une bourse de la Délégation Générale à la Langue Française et aux Langues de France (DGLFLF). Les entretiens avec une assistante de recherche, basés sur les thèmes suivants, étaient supposés générer l’emploi d’une variété de temps verbaux : - Récits de rêve (imparfait) - Récits biographiques (personnage historique vs autobiographie) (PC vs PS) - Narration de film vs d’épisode historique (PC/ PRES vs PS) - Présentation de projets d’avenir vs conjectures (Futur périphrastique ou simple) Le corpus contient dix-sept occurrences de on va dire générés par deux des cinq informateurs : 15 par A. et 2 par J. Notre réflexion se basera donc sur 125 occurrences orales de 'on va dire'.

(Table 1, page 400) Metal content of different manganese nodules from cruise VA-04 (R/V Valdivia) in the Pacific Ocean

Deep sea manganese nodules are considered as important natural resources for the future because of their Ni, Cu and Co contents. Their different shapes cannot be correlated clearly with their chemical composition. Surface constitution, however, can be associated with the metal contents. A classification of the nodules is suggested on the basis of these results. The iron content of the nodules strikingly shows relations to the physical properties (e.g. density and porosity). The method of density-measurement is the reason for this covariance. The investigation of freeze-dried nodular substance does not give this result. The Fe-rich nodules lose more hydration water than the Fe-poor ones during heat drying. The reason for this effect is the different crystallinity, respectively the particle size. The mean particle size is calculated on the basis of geometrical models. The X-ray-diffraction analysis proves the variation of crystallinity in connection with the Fe-content, too. The internal nodular textures also show characteristic distinctions.

Chemical composition of manganese micronodules from expedition VA-05/1 in the Pacific Ocean

A radioisotope energy-dispersive X-ray (EDX) system has been used on board the German research vessel "Valdivia" during an exploration expedition in the northern equatorial Pacific in 1973. The instrumentation used consisted of an X-ray detection system incorporating a 30 mm2 effective-area Si (Li) detector with a measured energy resolution of 195 eV for Mn K alpha X-rays, standard nuclear electronics, a 1024-channel analyser and a data read-out unit. The X-ray spectra in the manganese-nodule samples were excited by a 30-mCi 238Pu source. The six elements Mn, Fe, Co, Ni, Cu and Zn were analysed on board. Precision values for the analyses were less than 3% for Mn, Fe, Ni, Cu and Zn and about 5% for Co. A total amount of 350 analyses was carried out during a one-month cruise. Average contents of 190 analysed whole manganese-nodule samples from all the sampling sites of the covered area were 23.3% Mn, 6.7% Fe, 0.23% Co, 1.16% Ni, 0.94% Cu and 0.10% Zn. The average content of the base metals expressed as the sum of the Co, Ni, Cu and Zn contents was 2.48%. A linear relationship between Mn and Ni in all analysed samples, including whole manganese-nodule samples, zones of manganese nodules and manganese crusts, was observed. The Mn/Ni ratio calculated by regression analysis was 23.0. Zonal variations of the chemical contents of the six elements in the manganese nodules were found. A size classification of the manganese nodules has been suggested. Geochemical correlations of Cu and Ni versus Mn/Fe in the investigated samples are given.

Annotated record and chemical analyses of a polygenetic manganese nodule (slab) from the Scott Plateau, Indian Ocean (core VA-16-13KD)

A large manganese nodule (manganese slab) was dredged from 2100 m on the Scott Plateau by R.V. Valdivia in 1977. It is an irregular ellipsoid, with a maximum dimension of 28 cm, parallel to the sea floor. Chemical analyses show that Mn and Fe proportions are comparable, and total Ni + Cu + Co content averages 0.7%. The nodule has a complex growth history which started with radial upward growth leading to coalescing into a continuous crust. The crust was coated with horizontal layers. After fracturing and infilling of cracks with calcareous sediment, further layers encased the nodule.

Contesting postliberalism: governmentality or emancipation?

This article takes the form of a debate between two theorists who work with the concept of postliberalism. Following an introduction reflecting upon what is at stake in this debate, each contribution is organised in three sections. Firstly, as an opening gambit, both authors outline their basic understanding of the concept of postliberalism. Secondly, the authors stake out their very different claims as to whether or not postliberal approaches challenge neoliberal understandings sufficiently to create new conditions for emancipa- tion or merely maintain governmentality. In the respective final sections of their con- tributions, the authors clarify the workings of postliberal approaches in policy practice.

Revisiting the Late Jurassic-Early Cretaceous of the NW South Iberian Basin: new ages and sedimentary environments

The study of the Upper Jurassic-Lower Cretaceous deposits (Higueruelas, Villar del Arzobispo and Aldea de Cortés Formations) of the South Iberian Basin (NW Valencia, Spain) reveals new stratigraphic and sedimentological data, which have significant implications on the stratigraphic framework, depositional environments and age of these units. The Higueruelas Fm was deposited in a mid-inner carbonate platform where oncolitic bars migrated by the action of storms and where oncoid production progressively decreased towards the uppermost part of the unit. The overlying Villar del Arzobispo Fm has been traditionally interpreted as an inner platform-lagoon evolving into a tidal-flat. Here it is interpreted as an inner-carbonate platform affected by storms, where oolitic shoals protected a lagoon, which had siliciclastic inputs from the continent. The Aldea de Cortés Fm has been previously interpreted as a lagoon surrounded by tidal-flats and fluvial-deltaic plains. Here it is reinterpreted as a coastal wetland where siliciclastic muddy deposits interacted with shallow fresh to marine water bodies, aeolian dunes and continental siliciclastic inputs. The contact between the Higueruelas and Villar del Arzobispo Fms, classically defined as gradual, is also interpreted here as rapid. More importantly, the contact between the Villar del Arzobispo and Aldea de Cortés Fms, previously considered as unconformable, is here interpreted as gradual. The presence of Alveosepta in the Villar del Arzobispo Fm suggests that at least part of this unit is Kimmeridgian, unlike the previously assigned Late Tithonian-Middle Berriasian age. Consequently, the underlying Higueruelas Fm, previously considered Tithonian, should not be younger than Kimmeridgian. Accordingly, sedimentation of the Aldea de Cortés Fm, previously considered Valangian-Hauterivian, probably started during the Tithonian and it may be considered part of the regressive trend of the Late Jurassic-Early Cretaceous cycle. This is consistent with the dinosaur faunas, typically Jurassic, described in the Villar del Arzobispo and Aldea de Cortés Fms.

La voz del otro: rompiendo con la tradición del museo

Existe una actitud predominante en el mundo de los museos según la cual las diversas culturas se presentan y se respetan de manera adecuada, dándose un diálogo efectivo entre los museos y las comunidades culturales a las que sirven. Sin embargo, el presente trabajo disiente de dicha creencia, expone sus motivos, y sugiere una trayectoria por la que los museos pueden acercarse con éxito a tales objetivos. Lo que está en juego aquí es el ethos contemporáneo e histórico de los museos y su concepto de la identidad propia, lo que interfiere con su capacidad para incluir a “los otros”, excepto en sus propios términos. El propósito del museo en este sentido es mantener su voz preeminente y su prerrogativa intelectual en sus comunicaciones con el público al que sirve. La idea de que hay múltiples voces que necesitan ser escuchadas no es un concepto fácil de contemplar para los museos, y un paso positivo en aquella dirección representaría un cambio importante con consecuencias de largo alcance.
