ALT: Another Likelihood Tool

Although there are many phylogenetic reconstruc-tion tools available [1][4], their purpose is in generalto solve specific problems or to apply a limited num-ber of evolution models.We present a new program, ALT — AnotherLikelihood Tool, which implements Felsenstein’smaximum likelihood algorithm [2][3] two importantcharacteristics: it is written in a highly modular<lb...

The Einstein-dirac Equation on Riemannian Spin

We construct exact solutions of the Einstein-Dirac equation, which couples the gravitational field with an eigenspinor of the Dirac operator via the energymomentum tensor. For this purpose we introduce a new field equation generalizing the notion of Killing spinors. The solutions of this spinor field equation are called weak Killing spinors (WK-spinors). They are special solutions of the Einste...

ALT text and basic accessibility

Recent surveys have shown that the majority of websites are not accessible. Despite legal obligations and the importance of the internet for disabled people, most websites fail to reach a basic level of accessibility, yet web developers are not short of accessibility guidelines and recommendations. This preliminary study consists of a meta-review of web accessibility studies in order to identif...
