Abstract

Individuals with minor ischaemic stroke and intracranial occlusion are at increased risk of poor outcomes. Intravenous thrombolysis with tenecteplase might improve outcomes in this population. We aimed to test the superiority of intravenous tenecteplase over non-thrombolytic standard of care in patients with minor ischaemic stroke and intracranial occlusion or focal perfusion abnormality.

Due to non-homogeneous mass distribution and non-uniform velocity rate inside the Sun, the solar outer shape is distorted in latitude. In this paper, we analyze the consequences of a temporal change in this figure on the luminosity. To do so, we use the Total Solar Irradiance (TSI) as an indicator of luminosity. Considering that most of the authors have explained the largest part of the TSI modulation with magnetic network (spots and faculae) but not the whole, we could set constraints on radius and effective temperature variations (dR, dT). However computations show that the amplitude of solar irradiance modulation is very sensitive to photospheric temperature variations. In order to understand discrepancies between our best fit and recent observations of Livingston et al. (2005), showing no effective surface temperature variation during the solar cycle, we investigated small effective temperature variation in irradiance modeling. We emphasized a phase-shift (correlated or anticorrelated radius and irradiance variations) in the (dR, dT)-parameter plane. We further obtained an upper limit on the amplitude of cyclic solar radius variations, deduced from the gravitational energy variations. Our estimate is consistent with both observations of the helioseismic radius through the analysis of f-mode frequencies and observations of the basal photospheric temperature at Kitt Peak. Finally, we suggest a mechanism to explain faint changes in the solar shape due to variation of magnetic pressure which modifies the granules size. This mechanism is supported by our estimate of the asphericity-luminosity parameter, which implies an effectiveness of convective heat transfer only in very outer layers of the Sun., Comment: 17 pages, 2 figure, 1 table, published in New Astronomy

Abstract

Below 1 mHz, the power spectrum of helioseismic velocity measurements is dominated by the spectrum of convective motions (granulation and supergranulation) making it difficult to detect the low-order acoustic modes and the gravity modes. We want to better understand the behavior of solar granulation as a function of the observing height in the solar atmosphere and with magnetic activity during solar cycle 23. We analyze the Power Spectral Density (PSD) of eleven years of GOLF/SOHO velocity-time series using a Harvey-type model to characterize the properties of the convective motions in the solar oscillation power spectrum. We study then the evolution of the granulation with the altitude in the solar atmosphere and with the solar activity. First, we show that the traditional use of a lorentzian profile to fit the envelope of the p modes is not well suitable for GOLF data. Indeed, to properly model the solar spectrum, we need a second lorentzian profile. Second, we show that the granulation clearly evolves with the height in the photosphere but does not present any significant variation with the activity cycle., Comment: Paper accepted in A&A. 7 pages, 4 figures, 2 tables

Abstract

Recent models of variations of the Sun's structure with the 11-year activity cycle by Sofia et al (2005) predict strong non-homologous changes of the radius of subsurface layers, due to subsurface magnetic fields and field-modulated turbulence. According to their best model the changes of the surface radius may be 1000 times larger than those at the depth of 5 Mm. We use f-mode oscillation frequency data from the MDI instrument of Solar and Heliospheric Observatory (SOHO) and measurements of the solar surface radius variations from SOHO and ground-based observatories during solar cycle 23 (1996-2005) to put constraints on the radius changes. The results show that the above model overestimates the change of the radius at the surface relative to the change at 5Mm., Comment: 9 pages, 2 figures, ApJ Lett in press

21. Are non-magnetic mechanisms such as temporal solar diameter variations conceivable for an irradiance variability?

Abstract

Irradiance variability has been monitored from space for more than two decades. Even if data are coming from different sources, it is well established that a temporal variability exists which can be set to as approximately 0.1%, in phase with the solar cycle. Today, one of the best explanation for such an irradiance variability is provided by the evolution of the solar surface magnetic fields. But if some 90 to 95% can be reproduced, what would be the origin of the 10 to 5% left? Non magnetic effects are conceivable. In this paper we will consider temporal variations of the diameter of the Sun as a possible contributor for the remaining part. Such an approach imposes strong constraints on the solar radius variability. We will show that over a solar cycle, variations of no more than 20 mas of amplitude can be considered. Such a variability (far from what is reported by observers conducting measurements by means of ground-based solar astrolabes) may explain a little part of the irradiance changes not explained by magnetic features. Further requirements are needed that may help to reach a conclusion. Dedicated space missions are necessary (for example PICARD, GOLF-NG or SDO, scheduled for a launch around 2008); it is also proposed to reactivate SDS flights for such a purpose., Comment: 8 pages, 2 eps figures, published in Solar Physics

Abstract

We study the role played by the magnetic frustration in the antiferromagnetic phase of the organic salt \kappa-(BEDT-TTF)_ 2 Cu [N(CN)_2] Cl. Using the spatially anisotropic triangular Heisenberg model we analyze previous and new performed NMR experiments. We compute the 1/T_1 relaxation time by means of the modified spin wave theory. The strong suppression of the nuclear relaxation time observed experimentally under varying pressure and magnetic field is qualitatively well reproduced by the model. Our results suggest the existence of a close relation between the effects of pressure and magnetic frustration., Comment: 10 pages, 9 figures, to appear in Journal of Phys.: Condens Matter

27. The Sun Asphericities: Astrophysical Relevance

Abstract

Of all the fundamental parameters of the Sun (diameter, mass, temperature...), the gravitational multipole moments (of degree l and order m) that determine the solar moments of inertia, are still poorly known. However, at the first order (l=2), the quadrupole moment is relevant to many astrophysical applications. It indeed contributes to the relativistic perihelion advance of planets, together with the post-Newtonian (PN) parameters; or to the precession of the orbital plane about the Sun polar axis, the latter being unaffected by the purely relativistic PN contribution. Hence, a precise knowledge of the quadrupole moment is necessary for accurate orbit determination, and alternatively, to obtain constraints on the PN parameters. Moreover, the successive gravitational multipole moments have a physical meaning: they describe deviations from a purely spherical mass distribution. Thus, their precise determination gives indications on the solar internal structure. Here, we explain why it is difficult to compute these parameters, how to derive the best values, and how they will be determined in a near future by means of space experiments., Comment: 14 pages, 9 figures (see published version for a better resolution), submited to Proceedings of the Royal Society: Mathematical, Physical and Engineering Sciences

Abstract

The phase diagram of the layered organic superconductor $\kappa$-(ET)$_{2}$Cu[N(CN)$_{2}$]Cl has been accurately measured from a combination of $^{1}$H NMR and AC susceptibility techniques under helium gas pressure. The domains of stability of antiferromagnetic and superconducting long-range orders in the pressure {\it vs} temperature plane have been determined. Both phases overlap through a first-order boundary that separates two regions of inhomogeneous phase coexistence. The boundary curve is found to merge with another first order line related to the metal-insulator transition in the paramagnetic region. This transition is found to evolve into a crossover regime above a critical point at higher temperature. The whole phase diagram features a point-like region where metallic, insulating, antiferromagnetic and non s-wave superconducting phases all meet., Comment: 4 pages, 6 figures, Revtex

Abstract

Studies of the behaviour of diving animals usually focus on either individual dives or surface group activities, but these complementary observations are seldom combined in the same study. We here study the summer (June-October) behaviour of St. Lawrence Estuary belugas (Delphinapterus leucas (Pallas, 1776)) by combining fine-scale individual diving data from 27 time--depth--speed recorder deployments (conducted in 2002-2005) with surface activity data from 1413 focal herd follows (conducted in 1991-2012). We classified 6312 dives into seven dive types based on shape and swim speed. Dives were then combined into five bout types, including three pelagic, one benthic, and one near-surface. We classified surface activities of herds into six clusters, differentiated primarily by their associated movement patterns (milling or directional) and additionally by herd structure and dispersion and occurrence of acrobatic surface events. Finally, we used herd focal follows conducted while tracking an individual beluga to relate dive and bout types to surface activities. Results indicate that milling at the surface was more frequently related to benthic dives, potentially, associated with behaviours such as benthic foraging, resting, socializing, and care of young. Directional surface movements were more frequently associated with pelagic dives likely used during pelagic foraging, exploration, and travelling. Key words: behaviour, St. Lawrence beluga, dive classification, surface activities, Delphinapterus leucas. Les etudes du comportement des animaux plongeurs se concentrent habituellement sur les plongees individuelsoules activites de groupes en surface, mais ces observations complementaires sont rarement combinees dans une meme etude. Nous etudions le comportement estival (de juin a octobre) de belugas (Delphinapterus leucas (Pallas, 1776)) de l'estuaire du fleuve Saint-Laurent en combinant des donnees a fine echelle sur des plongees individuels obtenues de 27 deploiements d'enregistreurs de temps--profondeur--vitesse (de 2002 a 2005) a des donnees sur l'activite en surface de 1413 suivis de troupeaux (realises de 1991 a 2012). Nous avons classe 6312 plongees en sept types de plongees en fonction de la forme et de la vitesse de nage. Les plongees ont ensuite ete combines en cinq types d'episodes, dont trois pelagiques, un benthique et un pres de la surface. Nous avons classe les activites en surface des troupeaux en six groupes se distinguant principalement par leurs motifs de deplacements associes (erratiques ou directionnels), puis selon la structure et la dispersion du troupeau et la presence d'evenements acrobatiques a la surface. Enfin, nous avons utilise des suivis de troupeaux realises durant le suivi d'un individu en particulier pour relier les types de plongees et d'episodes aux activites en surface. Les resultats indiquent que les deplacements erratiques a la surface etaient plus frequemment associes a des plongees benthiques, potentiellement, a des comportements comme l'approvisionnement benthique, le repos, la socialisation et le soin des jeunes. Les mouvements directionnels en surface etaient plus frequemment associes a des plongees pelagiques vraisemblablement utilises durant l'approvisionnement pelagique, l'exploration et le deplacement sur de longues distances.

32. Identifying the critical habitat of Canadian vertebrate species at risk

Abstract

Identification of critical habitat is central to major conservation laws protecting endangered species in North America and around the world. Yet the actual ecological research that is required to identify which habitats are critical to the survival or recovery of species is rarely discussed and poorly documented. Here we quantitatively assess the information and methods used to identify critical habitat in the recovery strategies of 53 vertebrates at risk in Canada. Of the critical habitat identifications assessed, 17% were based on habitat occupancy information, 28% on habitat characteristics and (or) functions, and 40% assessed habitat suitability by linking functional use and biophysical characteristics. However, only 15% of the recovery strategies we evaluated examined relationships between habitat and population viability, abundance, individual fitness, or survival. Furthermore, the breadth of evidence used to assess critical habitats was weaker among long-lived taxa and did not improve over time. Hence, although any approach used to identify critical habitat is likely to be a step in the right direction in minimally protecting and maintaining habitats supporting critical life-cycle processes, there is a persistent gap between the widely recognized importance of critical habitat and our ability to quantitatively link habitats to population trends and individual fitness. Key words: critical habitat, species at risk, Species at Risk Act, behaviour, habitat use, habitat selection, functional habitat, individual fitness, population survival, recovery target. L'identification des habitats essentiels est au centre d'importantes lois sur la conservation visant a proteger les especes menacees en Amerique du Nord et dans le monde entier. Pourtant, la recherche en ecologie necessaire pour cerner les habitats essentiels a la survie ou au retablissement d'especes est rarement abordee et mal documentee. Nous evaluons de maniere quantitative l'information et les methodes utilisees pour cerner les habitats essentiels dans les strategies de retablissement de 53 especes de vertebres en peril au Canada. Des identifications d'habitats essentiels evaluees, 17 % reposaient sur des renseignements sur l'occupation de l'habitat, 28 % sur les caracteristiques ou fonctions de l'habitat et 40 % evaluaient la convenabilite de l'habitat en reliant l'utilisation fonctionnelle a des caracteristiques biophysiques. Cependant, seuls 15 % des strategies de retablissement evaluees examinaient les liens entre l'habitat et la viabilite de la population, l'abondance, l'aptitude individuelle ou la survie. En outre, l'etendue des donnees probantes utilisees pour evaluer les habitats essentiels est plus faible pour les taxons longevifs et ne s'ameliore pas avec le temps. Donc, si toute approche employee pour cerner les habitats essentiels devrait etre un pas dans la bonne direction parce que, minimalement, elle permet de proteger et maintenant les habitats qui supportent des processus essentiels du cycle biologique, un ecart persiste entre l'importance generalement reconnue des habitats essentiels et la capacite de relier quantitativement les habitats a des tendances demographiques et a l'aptitude individuelle.
