Observations from space with CoRoT and Kepler have revealed the rich pulsation spectra that characterize the long period hot B subdwarf (sdB) pulsators of the V1093 Her type. These evolved and compact helium core burning stars can develop low amplitude oscillations with periods in the range ∼ 1 − 4 hours that correspond to low degree, mid to high order g-modes. These modes have the property to penetrate deep inside the star, down to the boundary of the central convective core. They are consequently particularly interesting as asteroseismic probes. Here we briefly review how the g-modes behave in sdB stars, focusing in particular on the seismic signatures coming from the core itself. We also briefly summarize the first seismic results obtained from space data in pioneering efforts to exploit the potential of long period sdB pulsators as deep probes of the core structure.

In this paper, we give an updated overview of the observed characteristics of g-mode pulsations in slowly pulsating B stars. These characteristics are based on the combined results of linear nonadiabatic analysis of the oscillations and a photometric and spectroscopic mode identification for a sample of 13 members. For 4 stars, at least one mode is stable in all the considered theoretical models. [less ▲]

Hot B subdwarfs (sdB) are hot and compact helium core burning stars of nearly half a solar mass that can develop pulsational instabilities driving acoustic and/or gravity modes. These evolved stars are expected to be chemically stratified with an almost pure hydrogen envelope surrounding a helium mantle on top of a carbon/oxygen enriched core. However, the sdB stars pulsating in g-modes show regularities in their observed period distributions that, surprisingly (at first sight), are typical of the behavior of high order g-modes in chemically homogeneous (i.e., non-stratified) stars. This led to a claim that hot B subdwarfs could be much less chemically stratified than previously thought. Here, we reinvestigate trapping effects affecting g-modes in sdB stars. We show that standard stratified models of such stars can also produce nearly constant period spacings in the low frequency range similar to those found in g-mode spectra of sdB stars monitored with Kepler.

G-rich DNA sequences are able to fold into structures called G-quadruplexes. To obtain general trends in the influence of loop length on the structure and stability of G-quadruplex structures, we studied oligodeoxynucleotides with random bases in the loops. Sequences studied are dGGGWiGGGWjGGGWkGGG, with W = thymine or adenine with equal probability, and i, j, and k comprised between 1 and 4. All were studied by circular dichroism, native gel electrophoresis, UV-monitored thermal denaturation, and electrospray mass spectrometry, in the presence of 150 mM potassium, sodium, or ammonium cations. Parallel conformations are favored by sequences with short loops, but we also found that sequences with short loops form very stable multimeric quadruplexes, even at low strand concentration. Mass spectrometry reveals the formation of dimers and trimers. When the loop length increases, preferred quadruplex conformations tend to be more intramolecular and antiparallel. The nature of the cation also has an influence on the adopted structures, with K+ inducing more parallel multimers than NH4+ and Na+. Structural possibilities are discussed for the new quadruplex higher-order assemblies. [less ▲]

The structural properties of G-quadruplex forming sequences. such as the human telomeric repeat d(T(2)AG(3))(n), are of great interest due to their role in cancer and cellular aging. To determine if G-quadruplexes are present in a solvent-free environment. different lengths of the telomeric repeat d(T(2)AG(3))(n) (where n = 1, 2, 4 and 6) and dTG(4)T were investigated with mass specteometry, ion mobility and molecular dynamics calculations. Nano-ESI-MS illustrated quadruples stoichiometries compatible with G-quadruplex Structure.; for each sequence, with dT(2)AG(3) and dTG(4)T forming 4-strand complexes with two and three NH4+ adducts. d(T(2)AG(3))(2) a 2-strand complex. and d(T(2)AG(3))(4) and d(T(2)AG(3))(6) remaining single-stranded. Experimental cross sections were obtained for all species using ion mobility method.,. In all case.,. these could be quantitatively matched to model cross sections with specific strand orientations (parallel/antiparallel) and structures. For each species, the solvent-free structures agreed with the solution CD measurements, but the ion mobility/modeling procedure often gave Much more detailed structural information.

In response to DNA damage, p53 activates a G1 cell cycle checkpoint, in part through induction of the cyclin-dependent kinase inhibitor p21(Waf1/Cip1). Here we report the identification of a new direct p53 target, Ptprv (or ESP), encoding a transmembrane tyrosine phosphatase. Ptprv transcription is dramatically and preferentially increased in cultured cells undergoing p53-dependent cell cycle arrest, but not in cells undergoing p53-mediated apoptosis. This observation was further confirmed in vivo using a Ptprv null-reporter mouse line. A p53-responsive element is present in the Ptprv promoter and p53 is recruited to this site in vivo. Importantly, while p53-dependent apoptosis is intact in mice lacking Ptprv, Ptprv-null fibroblasts and epithelial cells of the small intestine are defective in G1 checkpoint control. Thus, Ptprv is a new direct p53 target and a key mediator of p53-induced cell cycle arrest. Finally, Ptprv loss enhances the formation of epidermal papillomas after exposure to chemical carcinogens, suggesting that Ptprv acts to suppress tumor formation in vivo. [less ▲]

Le G1000 est une initiative citoyenne dont l’ambition est d’être un nouvel outil démocratique, complémentaire aux élections et plus généralement à la démocratie représentative. Concrètement, le projet est conçu comme une fusée à trois étages. D’abord, et elle a été lancée début juillet, une consultation en ligne de grande envergure pour connaître les sujets de préoccupation des habitants de ce pays qui pourront alors être discutés lors de l’étape suivante. Ensuite, une journée de délibération le 11 novembre 2011 rassemblera 1000 personnes, sélectionnées de manière indépendante et aléatoire afin de refléter – le plus possible – la diversité de notre pays, à Tour & Taxis à Bruxelles. Rassemblés autour de 100 tables de 10 personnes, les citoyens choisis au hasard et préalablement armés des connaissances techniques nécessaires à la discussion tenteront d’élaborer quelques propositions relatives aux thèmes jugés prioritaires. Enfin, un plus petit groupe de citoyens (un G24), dans les mois qui suivent, affinera ces propositions pour formuler des suggestions concrètes à l’issue de trois week-ends de délibération. Mais le G1000, par son caractère inédit, ne manque pas de soulever des interrogations qui ne peuvent être négligées. Des choix importants ont été faits par les initiateurs et ceux-ci méritent d’être expliqués. Ils concernent le financement de l’initiative, la sélection des thèmes et des participants et enfin le but même du G1000. [less ▲]

The initiative we are going to discuss in this lead piece is the G1000 in Belgium. Contrary to most other initiatives by researchers or government agencies (Reuchamps, Forthcoming 2013), the G1000 project is a more hybrid type of deliberative event. There are certain characteristics that set it apart from other initiatives, such as the way in which the agenda of the event was set, the scale of the event, and the fact that is was a grass-root initiative by and for citizens. Because of its hybrid form, the G1000 deserves special attention. In this chapter, we first sketch the general background against which deliberative democracy in general – and the G1000 in particular – came about, after which we show that there is an ever-growing experience with deliberative events, and we highlight some of the main characteristics of these events. Next, we go into detail on the ideas and the methodological choices behind the G1000 project. And finally, we offer an overall evaluation of the project. [less ▲]
