Modelling hippocampal neurogenesis across the lifespan in seven species [PDF]
, 2011 The aim of this study was to estimate the number of new cells and neurons added to the dentate gyrus across the lifespan, and to compare the rate of age-associated decline in neurogenesis across species. Data from mice (Mus musculus), rats (Rattus norvegicus), lesser hedgehog tenrecs (Echinops telfairi), macaques (Macaca mulatta), marmosets (Callithrix

Is happiness u-shaped in age everywhere? A methodological reconsideration for Europe [PDF]
arXiv, 2021 A recent contribution to research on age and well-being (Blanchflower 2021) found that the impact of age on happiness is "u-shaped" virtually everywhere: happiness declines towards middle age and subsequently rises, in almost all countries. This paper evaluates that finding for European countries, considering whether it is robust to alternative ...

Modeling statistical properties of the X-ray emission from aged Pulsar Wind Nebulae [PDF]
, 2013 The number of known PWNe has recently increased considerably, and the majority of them are now middle-age objects. Recent studies have shown a clear correlation of both X-ray luminosity and size with the PWN age, but fail in providing a thorough explanation of the observed trends.

Rodin, Vigeland and the Middle Ages
Kunst og Kultur, 2020 In his search for an effective form for his famous Burghers of Calais (1884–1895), Auguste Rodin seems to have looked at medieval models. The emotional expressiveness of medieval sculpture also inspired Gustav Vigeland who refers in his early works to ...

XMM observations of three middle-aged pulsars [PDF]
arXiv, 2003 X-ray observations of middle-aged pulsars allow one to study nonthermal radiation from pulsar magnetospheres and thermal radiation from neutron star (NS) surfaces. In particular, from the analysis of thermal radiation one can infer the surface temperatures and radii of NSs, which is important for investigating evolution of these objects and ...

X-ray Emission from Middle-Aged Gamma-Ray Pulsars [PDF]
arXiv, 2015 Electrons/positrons produced in a pulsar magnetosphere emit synchrotron radiation, which is widely believed as the origin of the non-thermal X-ray emission detected from pulsars. Particles are produced by curvature photons emitted from accelerated particles in the magnetosphere. These curvature photons are detected as pulsed $\gamma$-ray emissions from
