A circle graph is the intersection graph of a family of chords on a circle. There is no known characterization of circle graphs by forbidden induced subgraphs that do not involve the notions of local equivalence or pivoting operations. We characterize circle graphs by a list of minimal forbidden induced subgraphs when the graph belongs to one of the following classes: linear domino graphs, P4-t...

This article presents findings from the Changing Youth Labour Markets and Schools to Work Transitions in Modern Britain projects undertaken between 2009 and 2010. The projects examined young people’s experiences and perceptions about study, work, and the future while going through transitions. The target group was young people on vocational courses at further education colleges in London aged b...

We derive the gravitational Hamiltonian starting from the Gauss-Bonnet action, keeping track of all surface terms. This is done using the language of orthonormal frames and forms to keep things as tidy as possible. The surface terms in the Hamiltonian give a remarkably simple expression for the total energy of a spacetime. This expression is consistent with energy expressions found in hep-th/02...

We carry them in our skin pores through entire life, from birth to death. offer shelter and return, they tidy-up pores. go on with busy day life sleep. They wake up when we sleep while are deeply dreaming, move around, visit other mates, reproduce. Despite being ‘very own’ companions, until recently, knew very little about their struggle.

A rich set of statistical techniques has been developed over the last several decades to estimate spatial extent animal home ranges from telemetry data, and new methods continue be developed. Here we investigate home-range estimation a computational point view aim provide general framework for computing ranges, independent specific estimators. We show how such workflow can help make easier more...
