Space plasmas are often observed to contain more particles in the high-energy tail than the usual Maxwellian distributions, and are well modeled by kappa distributions. The hybrid kappa-Maxwellian distribution and associated generalized plasma dispersion function Z(kappa M) were recently introduced to model magnetized space plasmas. The susceptibility tensor for a kappa-Maxwellian plasma component is derived, making use of Z(kappa M). This enables one to make general studies of obliquely propagating electromagnetic waves in a magnetoplasma. The susceptibility and dielectric tensors reduce to the Maxwellian expressions in the limit kappa ->infinity. As an illustration, the formalism is applied to the lower branch of the R mode and its off-parallel variant. For low kappa values, low-wavenumber, low-frequency parallel whistler waves are shown to be stable, unlike the Maxwellian case, which is unstable if the perpendicular temperature exceeds the parallel temperature. A numerical study is made of the effects of the value of kappa, the propagation angle, and the temperature anisotropy ratio on dispersion and damping. The kappa-Maxwellian distribution with very low kappa is found to be unstable in an overdense plasma near the electron-cyclotron frequency even when the parallel and perpendicular temperatures are equal, because of the anisotropy of the contours in velocity space.

Waves in pair plasmas have a fundamentally different dispersion due to the equal charge-to-mass ratios between negative and positive charges, which mix different time scales. In view of possible applications, e. g., to electron-positron and fullerene pair plasmas, stationary nonlinear structures are investigated for oblique or perpendicular propagation with respect to the static magnetic field. A generalized large amplitude extraordinary mode is found, having a linearly polarized electric field that is orthogonal to both the directions of wave propagation and of the static magnetic field. When the Alfvenic Mach number is in a suitably defined range, the pseudoenergy integral admits solutions with a negative wave electric field, in a cone around parallel propagation, and solutions with a positive wave electric field, at all angles of propagation. The exact analytical solution describing these solitary waves has also been obtained. At weakly nonlinear amplitudes, the solutions reduce to familiar solutions of the Korteweg-de Vries or modified Korteweg- de Vries equations. (C) 2005 American Institute of Physics. [less ▲]

Neurogenesis is a dynamic process that produces a diverse number of glial and neural cell types from a limited number of neural stem cells throughout development and into adulthood. After an initial period of amplification through symmetric division, neural stem cells rely on asymmetric modes of division to self-renew while producing more committed progeny. Understanding the molecular mechanisms regulating the choice between symmetric and asymmetric modes of division is essential to understand human brain development and pathologies, and to explain the increasing cortical complexity observed in evolution. A popular model states the existence of a causal relationship between the orientation of the axis of division of stem cells and the fate of their progeny in many different tissues, but the validity of the model in neural stem cells is not clear. In this review, we briefly present the diversity of neural stem cells and intermediate progenitors in the developing central nervous system. We then draw a historic overview of the assumed causal relationship between spindle orientation and fate determination. We show how this prompted a search for regulators of spindle orientation, and present the current state of knowledge on the mechanism. Finally, we review data on the effect of defective spindle orientation and try to integrate conflicting observations by presenting alternative mechanisms that may regulate the choice between symmetric and asymmetric outcomes.

Aims. Our goal is to probe the populations of obscured and unobscured AGN investigating their optical-IR and X-ray properties as a function of X-ray flux, luminosity and redshift within a hard X-ray selected sample with wide multiwavelength coverage. Methods. We selected a sample of 136 X-ray sources detected at a significance of >= 3 sigma in the 2-10 keV band (F2-10 greater than or similar to 10(-1)4 erg cm(-2) s(-1)) in a similar to 1 deg(2) area in the XMM Medium Deep Survey (XMDS). The XMDS area is covered with optical photometry from the VVDS and CFHTLS surveys and infrared Spitzer data from the SWIRE survey. Based on the X-ray luminosity and X-ray to optical ratio, 132 sources are likely AGN, of which 122 have unambiguous optical - IR identification. The observed optical and IR spectral energy distributions of all identified sources are fitted with AGN/galaxy templates in order to classify them and compute photometric redshifts. X-ray spectral analysis is performed individually for sources with a sufficient number of counts and using a stacking technique for subsamples of sources at different flux levels. Hardness ratios are used to estimate X-ray absorption in individual weak sources. Results. 70% of the AGN are fitted by a type 2 AGN or a star forming galaxy template. We group them together in a single class of "optically obscured" AGN. These have "red" optical colors and in about 60% of cases show significant X-ray absorption (N-H > 10(22) cm(-2)). Sources with SEDs typical of type 1 AGN have "blue" optical colors and exhibit X-ray absorption in about 30% of cases. The stacked X-ray spectrum of obscured AGN is flatter than that of type 1 AGN and has an average spectral slope of Gamma = 1.6. The subsample of objects fitted by a star forming galaxy template has an even harder stacked spectrum, with Gamma similar to 1.2-1.3. The obscured fraction is larger at lower fluxes, lower redshifts and lower luminosities. X-ray absorption is less common than "optical" obscuration and its incidence is nearly constant with redshift and luminosity. This implies that at high luminosities X-ray absorption is not necessarily related to optical obscuration. The estimated surface densities of obscured, unobscured AGN and type 2 QSOs are respectively 138, 59 and 35 deg(-2) at F > 10-14 erg cm(-2) s(-1). [less ▲]

Epilepsy is a chronic disease, requiring a medical treatment which is essentially preventive (avoiding further seizure). Because of these characteristics, one third to one half of the epileptic patients does not always comply with their treatment. In this article, we review the different factors of poor compliance. Some are specific to this medical condition while others are more general, like treatment complexity. We list here some suggestions to improve the compliance of the epileptic patient in routine medical practice. [less ▲]

Low adherence to therapies has been repeatedly described as a major determinant of poor clinical outcomes in chronic disorders. Bisphosphonates, the most widely prescribed drugs in this field, have been linked to a 12-month persistence lower than 40%. The situation is improved when using the weekly formulation compared to the daily intake of the drug. Low compliance results in lesser increase in bone mineral density and decreased anti-fracture efficacy. New medications, currently developed for the management of osteoporosis, will be user-friendly, allowing to an improvement of compliance and persistence. [less ▲]

L’observance thérapeutique peut être définie comme le degré de concordance entre le comportement d’un individu (en termes de prise médicamenteuse, suivi de régime et changement de style de vie) et les prescriptions ou recommandations médicales, soit plus simplement la capacité d’une personne à prendre un traitement selon une prescription donnée. La mauvaise observance est fréquente en gériatrie et est liée à la fois au comportement du patient, mais aussi des prescripteurs et des distributeurs de médicaments. Son impact est à la fois médical, fonctionnel et économique; ce suivi thérapeutique mal adapté est un des responsables de la pathologie iatrogène si souvent constatée chez la personne âgée. Afin de faire face de la manière la plus efficace possible à cette problématique, une démarche standardisée d’éducation thérapeutique doit être développée en définissant clairement les objectifs, les moyens et le suivi, en impliquant le patient quand cela est possible et en mettant en place des aides humaines et matérielles [less ▲]
