Effect of tree logging on reproductive performance in Blue Tits (Cyanistes caeruleus)

Journal of Ornithology, Sep 22, Seyed Mehdi Amininasab, Charles C. Y. Xu, Sjouke A. Kingma, et al.

For birds, habitat quality is largely determined by local vegetation, and reproductive performance can therefore be negatively influenced by anthropogenic activities. A tree logging event enabled us to examine the effect of removing trees of different maturities and types on the reproductive performance of Blue Tits (Cyanistes caeruleus). Against expectations, only the logging of ...

Unification of gauge couplings in radiative neutrino mass models

Journal of High Energy Physics, Sep 01, Claudia Hagedorn, Tommy Ohlsson, Stella Riad, et al.

We investigate the possibility of gauge coupling unification in various radiative neutrino mass models, which generate neutrino masses at one- and/or two-loop level. Renormalization group running of gauge couplings is performed analytically and numerically at one- and two-loop order, respectively. We study three representative classes of radiative neutrino mass models: (I) minimal ...

Reserve and Reserve-building activities research: key challenges and future directions

BMC Neuroscience, Sep 15, Carolyn Schwartz, Bruce Rapkin, Brian Healy

Background The concept of Cognitive Reserve has great appeal and has led to an interesting and important body of research. We believe, however, that it is unnecessarily limited by ‘habits’ of measurement, nomenclature, and intra-disciplinary thinking. Main body A broader, more comprehensive way of conceptualizing Reserve is proposed that invokes a broader measurement approach, ...

Leptogenesis parametrized by lepton mass matrices

The European Physical Journal C, Sep 01, Pei-Hong Gu, Xiao-Gang He

The conventional seesaw-leptogenesis can simultaneously explain the suppression of neutrino masses and the generation of cosmic baryon asymmetry, but usually it cannot predict an unambiguous relation between these two sectors. In this work we shall demonstrate a novel left–right symmetric scenario, motivated to solve the strong CP problem by parity symmetry, where the present ...

A folk theorem with codes of conduct and communication

Economic Theory Bulletin, Sep 16, Juan I. Block, David K. Levine

We study self-referential games in which players have the ability to commit to a code of conduct—a complete description of how they play and their opponents should play. Each player receives a private signal about each others’ code of conduct and their codes of conduct specify how to react to these signals. When only some players receive informative signals, players are allowed to ...
