We calculate the axion emission rate from reactions involving thermal pions in matter encountered supernovae and neutron star mergers, identify unique spectral features, explore their implications for astrophysics particle physics. find that it is about 2--5 times larger than nucleon-nucleon bremsstrahlung, which past studies was considered to be dominant process. The spectrum also found much h...

Demanding that charged Nariai black holes in (quasi-)de Sitter space decay without becoming super-extremal implies a lower bound on the masses of particles, known as Festina Lente (FL) bound. In this paper we fix $\mathcal{O}(1)$ constant and elucidate various aspects it, well extensions to $d>4$ situations with scalar potentials dilatonic couplings. We also discuss phenomenological implication...

A general formulation of the basic conflict information problem is given, encapsulated in a "black hole theorem." This framed more context than usual one quantum field theory on background, and based describing black as subsystem larger system, including its environment. sharpens limited set possible consistent options; with Coleman-Mandula theorem, most important point probably loophole "theor...

ABSTRACT This paper holds that the standard economic accounts of corruption based on expected costs and benefits are insufficient to understand tackle dishonesty in real world. It embarks a survey literature discuss major roles automatic judgments decisions, as well cognitive biases social preferences might play deviations from honest behavior. The further discusses implications behavioral econ...

The oxygen carrier hemocyanin occurs in the blood of Scutigera coleoptrata, a uniramous arthropod, as well as the crustaceans and chelicerates. The native polymer appears to be composed of substructures having the same size and electron-dense image as those of other arthropod hemocyanins but assembled into a unique multiple and arranged in a unique configuration. The simplest explanation of the...
